Bags And Fabrics And Their Usage Knowledge

　　 1. luggage fabric --- polyester polyester fiber (polyester, nylon Oxford fabric)

Also known as POLYESTER, is characterized by good ventilation and humidity. It also has strong anti acid, alkaline and anti ultraviolet ability.

　　 2. luggage fabric - spandex - stretch nylon (polyester, nylon Oxford fabric)

Also known as SPANDEX, the advantages are high elasticity, high flexibility and good recovery. General use of 2% can improve the fabric sense of movement, draping and maintenance. The weak point is that it is resistant to alkalinity, and it can be yellow and brittle after exposure to chlorine or ultraviolet radiation. Poor heat resistance. Often used as auxiliary materials blended with other materials. The more famous materials are the LYCRA of American DUPON, the "Dorlastan" of German Bayer (Bayer), and the Roica of Japanese A.k (Xu Huacheng).

　　 3. luggage fabric - Nylon - nylon (polyester, nylon Oxford fabric)

Also known as Nylon, polyamide fiber. The advantages are high strength, high wear resistance, high chemical resistance, good resistance to deformation and aging resistance. The disadvantage is that the handle is hard. The more famous ones are PERTEX, CORDURA3. luggage fabric --- nylon nylon (polyester, nylon Oxford fabric), also known as Nylon, polyamide fiber.

　　 Fiber materials related indicators:

D: Daniel, a measure for measurement. Spin The unit of fiber density is a gram showing the weight of each 9000 meter fiber (that is, the lower the Neal, the thinner the fiber). Formula D=G/L*9000. That is fiber weight / fiber length *9000. It is commonly used in fabric strength index of knapsack fabric. Commonly used 450D, 500D. Materials above 500D are generally used for easy wearing parts. Like the bottom of the backpack.

T: tex, referred to as "special", a unit for measuring the density of textile fibers. It refers to the weight grams of 1000 meter long fibers or yarns at a constant moisture regain. Formula T=G/L*1000. That is fiber weight / fiber length *1000.

TX = shrink treatment RS = anti tear N = nylon P = polyester fiber

TXN 1000 polyester, nylon Oxford fabric: very tough and wear-resistant. cloth And fabrics, which are easier to produce friction parts in climbing special backpacks and large backpacks.

TXN 500 polyester, nylon Oxford fabric: fabric and fabric made of compact nylon fabric, used in hiking and light weight backpack.

RSN 500 GRID polyester, nylon Oxford fabric: add TXN 500 cloth to black anti split fiber, mix woven fabric and fabric.

RSN 500 polyester, nylon Oxford fabric: nylon fabric is used as braiding material to make fabrics and fabrics similar to anti split structures.

TXP 900 polyester, nylon Oxford fabric: fabric and fabric made of 900 polyester polyester fabric used for easy wear and tear in hiking backpacks and small backpacks.

TXP 600 polyester, nylon Oxford fabric: polyester fabric and fabric that has been used for many years has excellent touch and quality.

RSP 600 polyester, nylon Oxford fabric: improved from TXP 600, with anti tear fiber structure.

SRN 420 polyester, nylon Oxford fabric: a small area of nylon fabric and fabric, which has the function of anti tearing. It is used on top of the technology backpack to increase the strength of the fabric and reduce the weight of the backpack.

SRN 210 polyester, nylon Oxford fabric: small area of nylon fabric and fabric, it has the function of anti split, used in the large backpack to achieve the effect of reducing the weight of the backpack.

MNP420 polyester, nylon Oxford fabric: this fabric and fabric look metallic.

1680 NYLON polyester, nylon Oxford fabric: this tough fabric is often used in travelling bags.

The raw materials used for cloth and fabric used in bags are two kinds of Nylon and Poly, and occasionally mix with two kinds of materials. Nylon is nylon, Poly is polyethylene, these two materials are extracted from petroleum, Nylon is better than Poly quality. From the fabric, Nylon feels softer. For example, N.1000D CORDURA, that is, nylon CORDURA of 1000D, is material + fiber + textile method.

D is the abbreviation of denier. Denier is a measure of fiber. The calculation method is: the weight of every 9000 meters long line is 1 grams, called Denier. (the lower the Neal, the thinner the fiber). Formula D=G/L * 9000. So the smaller the number in front of D, the smaller the line, the smaller the density. For example, the material of 210D is very thin. It is usually used as the lining of a bag or the interlayer. And 900D or 1000D material rough, thick lines, very wearable, generally used as the bottom of the bag.

　　 Some fabrics and fabrics that often appear in backpacks include:

　　 DuPont nylon fabric and fabric (CORDURA)

It is a kind of cloth and fabric invented by DuPont Co. It has the functions of light, fast drying, soft and durable, and it is not easy to discoloration for a long time. It is said that two different colors will appear in this kind of fabric at different angles. Apart from DuPont's company, others do not know how to produce this material. Generally woven with Nylon, with fiber strength (Denier) as the strength standard, with 160D, 210D, 330D, 420D, 600D, 900D, 1000D, etc., the higher the number is, the stronger the grain is. General 160D to 210D used in clothes On or used as a general outdoor bag. This material has a coating on the reverse side, and the moderate rain will not soak the material.

　　 Nylon fabric and fabric in Oxford (OXFORD)

The warp of Oxford spinning fabric and fabric is made of two strands, and the weft line is relatively thick. Its textile method is one up and down, it is a very common textile method. Generally 210D, 420D material. The reverse is coated. Used as a lining or compartment for a package.

　　 Imitation DuPont nylon fabric and fabric (KODRA)

KODRA is a fabric and fabric produced in Korea. To a certain extent, it can take the place of CORDURA. It is said that the inventor of this fabric originally wanted to find out how CORDURA was spun, but finally did not study it, but invented new fabrics and fabrics, which is KODRA. The fabric is also made of Nylon, and also fiber strength, such as 600D and 1000D. The reverse is coated, almost the same as CORDURA.

　　 High density nylon fabric and fabric (HD)

HD is the abbreviation of High Density, which means high density. Look, the fabric is almost the same as OXFORD. Usually 210D and 420D, usually used as the lining or compartment of a package. The reverse is coated.

　　 Nylon / nylon fabric and fabric (R/S)

R/S is the abbreviation of Rip stop. The fabric and fabric are nylon with small squares. Its toughness is stronger than that of ordinary nylon, and the rough side of the block outside the fabric is used. The grid is made of fine threads in the middle. Generally, there are 300D, 330D, 450D and so on, which can be used as the main material of backpack, such as big face, outer pocket and so on. The reverse is coated.

　　 Teague nylon fabric and fabric (Dobby)

The fabric of Dobby seems to consist of many very small lattices. But if you look closely, you will find that it is made of two threads, one thick and one thin, and the other is different from the reverse. Generally few coatings. The strength is much worse than CORDURA, usually only in casual bags or short trips bags. No need for climbing bags.

　　 Super strong nylon fabric and fabric (VELOCITY)

VELOCITY is also a nylon fabric and fabric. The intensity is very high. It is also commonly used in mountaineering bags. There are coated fabrics and fabrics on the reverse side. 420D or higher strength. The fabric and fabric front look very much like Dobby.

　　 Waterproof nylon fabric and fabric (TAFFETA)

TAFFETA is a very thin cloth and fabric with coating, and some coating is more than one time, so it has better waterproof performance. Generally do not make the main cloth and fabric of the backpack, only make a raincoat, or a rainproof cover for the backpack.

　　 Polyethylene fabric and fabric (Poly PU)

Poly is usually used instead. The density of Poly is generally 64t (low), 74t (medium) and 82t (high). The strength of fabric from 150D to 1800D is stronger and stronger. The general strength of 600D can be used as the bottom of a mountaineering bag, but its textile method is not as strong as that of CORDURA.

　　 AIR MESH

The general Chinese language is called the space network, which is different from the general network. Its net surface has a gap with the following material, generally 3mm or larger. It is this kind of gap that makes it have good ventilation performance, so it is usually used as a strap or back or other places close to the body. Generally, there are many specifications for the net. Nylon nets are usually used on bags only on both sides of the bags as sundries or water pockets.
