Fabrics, whether synthetic or natural, have certain characteristics. One of them, perhaps one of the most important, is the linear density of the threads from which the fabric is made. To measure this parameter, a unit is adopted, which is called denier, or den. Actually, one den means that a thread nine thousand meters long weighs one gram.

From here it is easy to determine that 600d polyester is a fiber (or a fabric made from this fiber, it is designated in the same way), nine kilometers of which weighs six hundred grams. It should be noted that this is a rather sick density. On average, for fibers from which fabrics are produced, the linear density can range from 100 to 900 den. There are also much denser fibers.

What does this 600d mean for polyester? First of all, it is an opportunity for comparison. For example, 600d fiber is much stronger at tear and thicker than 450d fiber. But only identical fibers can be compared with each other. For example, 600d nylon is stronger than 600d polyester due to the initial difference in physical characteristics these fibers.

Fabric based on 600d polyester fibers has a wide range of applications due to its strength, density, low electrical conductivity, resistance to aggressive atmospheric factors and water repellency. 600d polyester fabric made using Rip Stop technology is used to sew, for example, camping equipment, including backpacks, tents, jackets, various covers and the like. Sometimes such a fabric is impregnated with a special polyvinyl chloride composition in order to enhance its water-repellent properties.

600d polyester fabric is also popular with enterprises light industry who use it for sewing clothes or its elements.

Increasingly, when buying clothes, curtains, bedding, you can see polyester in the composition of the fabric.

This material today is gaining well-deserved popularity due to its properties and ease of care.

The second name of this material is polyester, it is made synthetically from polyester fibers obtained from polystyrene - products of oil and hydrocarbon processing.

Today, among all synthetic fabrics, it occupies the first place. World textile production in 50% relies on the properties of this particular fabric.

Products made from 100% polyester in their own way appearance can be thin, like a veil or chiffon, or strong, like a raincoat fabric. Sometimes they feel like wool or cotton to the touch. This diversity is explained by the structure of the fiber, the peculiarities of its processing, and the weaving of the fabric.

Both men's and women's products are made of polyester, less often - for children. They also sew covers and capes for furniture, curtains, carpets and much more.

History and production

The first experience of polyester production abroad dates back to the 30s of the last century. It appeared in Russia in 1949, and became widespread in the 60s in the production of packaging materials and adhesive tapes.

There are several main stages in the production of polyester:

1. preparation of the main raw materials - hydrocarbons and oil;
2. processing of raw materials with subsequent isolation of polystyrene;
3. production of liquid polyester from polystyrene;
4. chemical purification of the resulting mass;
5. formation of polyester fibers;
6. giving the fibers the required qualities;
7. canvas production.

To improve the properties of polyester or to produce high quality new material during the production process, polyester is combined with other fibers of both natural and artificial origin.

With strict observance of GOSTs in the technological process, the resulting material should not have a chemical smell or leave stains and traces of paint on the body.

The composition and characteristics of fabrics with polyester

• In combination with polyamide, a light, elastic material resembling silk is obtained. Differs in elasticity, wear resistance, well holds a form and color. The disadvantages include the low heat resistance of the fabric and its low hygroscopicity.
• The combination of polyester and elastane gives a material that stretches well and, at a low density, has good strength and breathability. However, things made from such fabric are sensitive to direct sunlight and may fade. Most often, socks, stockings, gloves and other tight-fitting things are made.
• When cotton is added to polyester, the ideal fabric for bedding and knitwear is obtained. The material is hygroscopic, sun-resistant, dries quickly and does not wrinkle.
• Polyester significantly improves the quality of viscose, making it more durable and resistant to color fading. In a ratio of 30% viscose and 70% polyester, it is ideal for sewing home and work clothes.

Polyester Density Unit

Den is an indicator of the linear density of threads in a fabric, the ratio between mass and length. 1d is 1 gram of thread per 9 kilometers. The higher the number, the greater the density.

• 300d- a fairly dense fabric, which is widely used in the manufacture of sports and tourist equipment, clothing and accessories, threads, yarn.
• 500d- a dense material from which equipment is made for various kinds sports. It is also used to make awnings for trucks, tents, backpacks and bags.
• 600d- characterized by resistance to external aggressive environment. It has low electrical conductivity and repels water well. The scope of the fabric is the same, but the products are obtained a class higher.
• 900d- such a density of the fabric does not pass not only water, but also ultra-violet rays. High quality equipment and workwear suitable for extreme conditions are sewn from it. By combining polyester with nylon, incredible strength and elasticity are achieved.

Types of 100% polyester fabrics

• Jordan- fabric with the addition of polyurethane. It has a smooth iridescent surface of high wear resistance. It is waterproof and windproof.
• Duspo– dense fabric with polyurethane impregnation. Able to repel water and dirt, protects from wind.
• Prince- matte silky fabric with waterproof impregnation and windproof properties.
• Bonding– dense, breathable fabric that protects against cold. It gives comfort and warmth in winter, so children's outerwear is sewn from it.
• Trilobal- has a beautiful mother-of-pearl sheen, and therefore clothes are sewn from it mainly for children and women.
• File- a fairly dense material with a good aesthetic appearance. The fabric is waterproof and windproof, dries quickly, keeps its shape and looks.
• Taffet- Resistant to moisture and impact chemical substances. The material is in demand in the production of equipment for tourists and rescuers.
• memory- the fabric remembers the previous impact on it - wrinkling or smoothing.

Advantages of polyester

The percentage of polyester in the canvas in relation to other materials may be different. However, even with a small content of its properties, it gives products a special value:

• the material does not wrinkle and does not require enhanced ironing;
• easy to wash and dries quickly;
• does not stretch and does not fade;
• products are light, strong and elastic;
• wear-resistant and durable;
• do not attract moths and other insects;
• have a low cost;
• do not absorb odors
• pleasing to the eye and touch.

Disadvantages of polyester

• due to the high density of things from this material, it is inconvenient to wear in the hot season;
• since polyester is synthetic, it accumulates static electricity that attracts dust and small debris; it is recommended to treat with antistatic;
• things are harsh, which can cause discomfort when worn;
• in case of violation technological process fabric produced can cause allergies.

Areas of use

Polyester, a synthetic fiber, has found wide application in the textile industry. Everything is sewn from it, from underwear to outerwear, overalls and uniforms, lining fabrics, bedding and covers for furniture and cars, school bags, backpacks, umbrellas, soft toys.

It can also act as a heater (synthetic winterizer, holofiber).

As before, 100% polyester is used to produce packaging materials, strapping tapes, towing ropes, which are able to withstand enormous loads, only slightly inferior to their metal counterparts. At the same time, the cost of such products is much lower.

Product Care Rules

• it is necessary to follow the manufacturer's recommendations for the care of the product indicated on the product label;
• the recommended temperature for washing is not higher than 40 ° C so that the product does not lose its shape;
• when machine washing, only a delicate mode with low spin speeds is selected;
• it is strictly forbidden to use bleach, as it can ruin the structure of the fabric;
• to reduce the electrification of things, you can add fabric softener when washing, or use a special antistatic agent;
• if necessary, the product is ironed from the wrong side through the iron, setting the temperature of the iron to a minimum.

Reviews

According to general assessment, products containing polyester are lightweight and comfortable. Such things are beautiful and much more practical than with a 100% natural composition.

It is noticed that after many washes the item retains its color and shape. Easy to remove stubborn stains and dries quickly.

There are many questions regarding the correct ironing of polyester products, which are solved by studying the basic rules for caring for things, as well as by purchasing a ceramic nozzle on the sole of an iron or gauze (according to the grandmother's method).

Another hello to all! Today I will “review” a “tactical” nylon (600D) black sling bag on one shoulder. detailed photos, detailed measurements of how it looks after ~ 5 months of operation, and also how this bag looks on the body - under the cut.

background
This is not my first bag. I passed the previous bag a la “vintage, made of leather” (see one of my previous reviews) to my brother (it fit him well). Before that, there were a couple more bags made of leatherette (a la "postman"). The bags were not bad, cheap, with a bunch of compartments, but the material of manufacture made itself felt after about ~ 1 year of wear - in some places the elements of the bag cracked, in some places it was completely wiped to a hole: D. I wore a leather bag for about six months, after which I decided to try something else (a good bag, but I don’t like the style a bit, and I don’t really like the brown color, I wanted black) already made of nylon. And most importantly - try a bag a la Sling, on one shoulder. What I didn’t really like about my past bags is that I usually throw the bag on my back (or so), which is why it hurries to be on its side with any movements. There is no such thing in this bag, plus, if desired, you can quickly throw it forward for quick access to the contents (and in general, you can safely carry it in front - I often use this opportunity).

After climbing and seeing what Ali offers, I settled on this bag. The material is 600D nylon (1000D, of course, is completely absurd and unkillable, but such bags are much more expensive, and I had the experience of touching a friend’s 1000D bag - it’s oaky, I’d rather be a little softer). In the stash, as usual, there was a coupon, which I hastened to apply.

I look again, the seller raised the price tag - something their fashion went to fake "sales" :D, in any case - the price tag for this bag fluctuates around ~ $ 30-35, I think you will find similar lots without problems (if the price of this seller is not arrange).

The main characteristics of the bag:

Material: nylon (600D)
Height (to the handle, taking into account the handle itself) - 31 cm (unfortunately, an A4 sheet does not fit).
Width - ~ 31 cm.
Thickness (when filled with nishtyaks) - 11 cm.
Other measurements (my personal, any pockets, etc.) - see already in the review itself further (they will be under the spoiler).

Details:
Bought on April 3, the seller sent the usual ChinaPost, picked up the parcel at the end of April:

Track info

The bag itself was in an ordinary bag with handles (slightly larger than the size of the bag itself), on top was a black bag with props. Considering that there is nothing to fight here, nothing happened to the bag. Inside the bag, as usual, the Chinese stuffed all sorts of waste paper for volume.
And inside, the seller threw a gift - a Velcro patch with an emblem from Transformers. The patch is small in size, ideal for a pocket on the strap.

Also, another strap like this came separately to the bag:


But I couldn’t find it - I dug up the whole house: D, but it was there. For me personally, a sock with such a strap is unacceptable (often you need to get quick access to the bag, it becomes almost impossible to do it with it), so I immediately put it off somewhere (you need to look at your leisure).

The photos will be up-to-date - for today (I remind you that I have been carrying a bag since 05.2015), i.e. You can judge for yourself how the bag has worn out over these ~ 4 months (I wore it almost every day).

Bag front (empty inside):

Back bag:

Let's move on to the branches. Let's start with the pocket under the lid. I’ll immediately show a photo of the plastic latch - it was rubbed a little during operation (scratches are visible, but they don’t catch your eye in life):

Open the lid and see the pocket:

And this is what it looks like from the inside:


At the very top you can see something of a film - this, as I understand it, is protection against water. I read that often after a couple of months of operation it begins to crumble and collapse, but for me, it seems, everything is ok with this. There are such inserts with this film in many compartments, most of all in the back.

Bottom pocket:

Additional small compartment on the bottom pocket, with Velcro:

Pen. Nice, strong, well made. She has a fixed position - i.e. when walking, it does not dangle back and forth (in my last bag, this “back and forth” dangling was pretty annoying):

Webbing pocket with velcro ( general form). On top of the lid we see a mount for all sorts of Velcro patches - this is where the “gift” with Transformers becomes ideal:

Webbing pocket (inside). From the inside, almost completely covered with a water-repellent “film”:

Lightning and caps close-up. When walking, they do not rattle and do not strain, which is a plus:


By the way, about lightning. In all compartments and pockets (except for the back compartment) - they are on both sides, which is also very convenient.

Bag on the side. We see molle mounts for various additional pouches / pockets:

bag on the other side. Everything is the same, the same molle mounts, and we also see a zipper - this is the entrance to the back compartment (you can climb into the back compartment in two ways - both from the front and from the back):

Bottom bag (stuffed with goodies):

Back compartment. The right wall is completely covered with a “film”. The largest compartment - comes right up to the strap:

Webbing (upper part). There are a couple of pockets on it (for reference, I inserted a marker and a pen into them):

The latch on the top of the strap (close-up):

The bottom of the strap. It keeps perfectly, I carried rather heavy objects in the bag - nothing was torn:

The lower part of the strap (on the other side). We see such a grid:

On the back of the bag, everything is also trimmed with such a grid:

And finally, let's open the head office and see what's there:


As you can see, there is also a small compartment on the back side (an 8.9-inch tablet fits perfectly into it, 10.1 did not fit).

In this bag, I usually carry such nishtyaks (+ phone (I took a photo on it - I didn’t get into the frame) + 8.9-inch tablet). Periodically, something else is added or replaced (for example, glasses are changed to an umbrella, etc.). The bag perfectly accepts the whole thing, in the “clogged” state it looks great - as in the photo from the seller.

More detailed measurements of individual elements - under the spoiler.

Operating Instructions
As I already wrote, I have been carrying a bag since May of this year in “city mode” (up to about 3 hours every day). I didn’t notice any particular fatigue (when the bag was full to the stop), if it did appear, I threw the bag back to front in order to transfer the load, I don’t feel discomfort with such a sock (and the armrest appears: D). For the entire period of operation, only plastic elements (latches) have poked around, in everything else - everything is fine, the water-repellent “film” is also in place. A couple of times I got into the rain (strong) the bag got wet, but inside everything was dry.
In general, a good, suitable bag, I liked it.

And as usual - a photo on the body

Oxford refers to synthetic fabrics, for the production of which they take either nylon threads of different thicknesses. It is distinguished by a special type of weaving called “matting” or “basket weaving”, which gives the fabric a uniform structure and shine.

The combination of weaving and synthetic thread provides high reliability of the finished product. To increase the strength of matter, designed for power loads, with manufacturing process the weft thread is made thicker than the warp.

The material is produced in different densities, which explains broad scope its applications: from ordinary clothes to shoes and special equipment. The color scheme of Oxford fabric depends on the purpose of the finished product, but blue is considered a classic color.

Rogozhka- a type of weaving linen (twill) weaving, in which the warp and weft threads are intertwined not one by one, but in groups, as a result of which a characteristic checkerboard texture is formed on the surface of the matter.

According to one version, it is believed that matting was invented in the old days by Russian craftsmen, weaving coarse fabric for household needs from the fibers of a plant called cattail (hence the name), which was later replaced by bast.

According to the official theory, the birthplace of Oxford fabric is Scotland at the end of the 19th century. Why the material was named after the ancient city of Great Britain is still a mystery. But it is known that shirts made of this fabric have become very popular among Oxford University students, and today they are a symbol of the prestige of US universities and an integral part of the dress code of financial corporations.

By the end of the 20th century, oxford began to be made from synthetic threads, thanks to which the fabric acquired new characteristics and began to be used in other areas of human activity.

Basic properties

Depending on the threads used, Oxford is divided into two types, each of which has its own distinctive properties.

• Nylon oxford- very strong elastic chemical-resistant material, sensitive to light and high temperatures. Capable of accumulating static electricity.
• Polyester Oxford in comparison with nylon, it is not so strong and flexible, but it surpasses it in light and heat resistance.

Despite their differences, both species have common properties:

• Wear resistance. Due to the strong weaving, synthetic fabric is resistant to external mechanical stress and can last for many years.
• Strength. The material is less susceptible to damage and abrasion of the fibers.
• Waterproof. It is carried out by applying PVC or polyurethane impregnation to the fabric, which repel not only water, but also dirt and dust, and also create wind protection.
• Durability due to the general properties of matter.

Varieties of Oxford

Marking

The types of fabric are determined by the thickness of the fibers used, as well as the water-repellent coating applied to the surface. As a rule, the thickness of the fibers is from 150 to 1600 den.

Den is a characteristic of the density of the fabric, denoted as "D". The numerical indicator in the marking provides information about the thickness of the thread and the density of the fabric. Depending on the impregnation of the fabric, next to the density indicator, there may be a corresponding letter designation: PU - polyurethane, PVC - polyvinyl chloride.

Types of fabric

• 150D- the thinnest material from which windbreakers, light jackets and raincoats, raincoats, covers, curtains are sewn.
• 210D- used in the production of clothing and accessories for tourism, hunting and fishing. They also sew uniforms for representatives of security and law enforcement agencies.
• 240D- backpacks, tents, covers and related equipment for tourism are sewn from it. Typically, a fabric of this density is impregnated with a polyurethane coating.
• 300D- quite hard and dense material. It is used in the shoe industry, in the production of bags, suitcases and other haberdashery, special equipment. Both types of water-repellent coating are applied to the fabric.
• 420D- used in tailoring outerwear and overalls, equipment for tourists and hunters, shoes and haberdashery, covers for sofas and armchairs. Impregnated with polyvinyl chloride and polyurethane.
• 600D- a fairly common water-repellent fabric, from which awnings, curtains, tents, folding tables and chairs, special equipment and overalls for extreme activities, covers for auto-, moto-, hydraulic engineering are sewn. Used in the production of frameless furniture.
• From 1500D- These are heavy and rigid products, usually made to order.

Application

• footwear industry;
• production of haberdashery;
• special equipment for fishing, hunting, tourism;
• uniforms for law enforcement agencies;
• production of carriages and sledges for children;
• furniture industry.

Advantages

• long service life;
• resistance to mechanical damage;
• wear resistance;
• lightness of products;
• low cost;
• ease of maintenance.

disadvantages

The disadvantages are primarily due to the source material for the fabric. If the oxford is made of polyester, its main disadvantage is the lack of density and flexibility in comparison with the nylon counterpart.

Nylon oxford is sensitive to high temperatures - if it is burned by fire, the edges of the material melt and do not crumble. Also, when exposed to light, it loses its color.

Common disadvantages include:

• lack of air exchange;
• the rustling of matter;
• a small range of possible colors.

Proper care of oxford

• hand or machine wash;
• water temperature - about 40 ° C;
• standard spin speed;
• ironing at temperatures up to 110°C;
• drying in a tumble dryer is acceptable;
• dry cleaning is allowed.

Be sure to read the care information provided by the manufacturer, as the fabric may be made with the addition of some fibers that require special care.

In case of contamination, it is enough to wipe the product with a damp cloth, erasing the dirt. If a tear has formed on the fabric, it can be sewn up and sealed.
