Knowledge of luggage fabrics

1. Polyester

Polyester refers to polyester fiber, also known as POLYESTER. Features: good air permeability and moisture discharge, as well as strong acid and alkali resistance and UV resistance.

2. Spandex

Spandex refers to stretch nylon, also known as SPANDEX. Advantages: high elasticity and high stretchability as well as good recovery. Generally, using 2% can improve the fabric's sense of movement, drape, and shape retention. Weaknesses: weak alkali resistance; easy to turn yellow and brittle after exposure to chlorine or ultraviolet rays, poor heat resistance. Spandex is often used as an auxiliary material and blended with other materials. The more famous materials are LYCRA from DUPON in the United States, "Dorlastan" from Bayer in Germany, and "Roica" from A.k. (Asahi Kasei) in Japan.

3. Nylon

Nylon refers to nylon, also known as Nylon, polyamide fiber. Advantages: high strength, high wear resistance, high chemical resistance, good deformation resistance, and aging resistance. Disadvantages: Hard feel. Famous ones include PERTEX and CORDURA

Related indicators of fiber materials

D: Denier, a unit used to measure the density of textile fibers, showing the weight of every 9,000 meters of fiber in grams (that is, the lower the denier, the finer the fiber). Formula D=G/L*9000. That is, fiber weight/fiber length*9000. Commonly used material strength indicators for backpack fabrics. Generally, 450D and 500D are commonly used. Materials above 500D are generally used in easily worn parts. Such as the bottom of a backpack.

T: Tex, referred to as "T", a unit used to measure the density of textile fibers. It refers to the weight of 1000 meters of fiber or yarn at the standard regain. Formula T=G/L*1000. That is, fiber weight/fiber length*1000.

TX = Shrink treated RS = Tear resistant N = Nylon P = Polyester

TXN 500: Fabric made of nylon fiber with a shrinkage structure, used in alpine hiking and lightweight backpacks.

TXN 1000: Very strong and wear-resistant fabric, used in climbing backpacks and large backpacks where friction is more likely to occur.

RSN 500GRID: Fabric made by adding black tear resistant fiber to TXN 500 fabric and weaving it together. RSN 500: Fabric similar to tear resistant fabric is made by using nylon fiber as the weaving material.

TXP 900: Fabric made of 900 denier polyester fiber, used in hiking backpacks and small and medium backpacks where wear is more likely. TXP 600: Polyester fabric that has been used for many years, with excellent touch and quality.

RSP 600: Improved from TXP 600, with tear resistant fiber structure.

SRN 420: A small area of nylon fiber fabric that is tear-resistant and is used on technical backpacks to increase the strength of the fabric and reduce the weight of the backpack.

SRN 210: A small area of nylon fiber fabric that is tear-resistant and is used on medium and large backpacks to reduce the weight of the backpack.

MNP420: This fiber fabric looks like a metallic texture.

1680NYLON: This tough fabric is often used on travel bags.
