The main original materials made into suitcases are Nylon and Poly, occasionally two materials mix together. Both Nylon and Poly are refined from petroleum, and quality of Nylon is better than Poly’s. In terms of fabric, Nylon is softer than Poly.

1. Dacron-polyester fibre

It can also be called polyester with the features of good air permeability and moisture removal. Apart from these features, dacron is anti alkali and acid, ultravioresistant.

2. Spandex-polyester

The advantages of spandex is in strong elasticity and good resilience. Usually, 2% added into the fabric will make the textile kinesthesia, overhanging. The weakness is weak in alkali resistance; and spandex is easy to turn yellow and embrittlement after ultraviolet irradiation and chlorine. Heat resistance is bad. Spandex is widely used as auxiliary materials that are mixed with other materials. The famous materials include LYCRA of DUPON in U.S, Dorlastan of Bayer in German and Roica of A.k in Japan.

3. Chinlon-nylon

It is also called perlon with the advantages of high strength, high abrasion resistance, high chemical and good resistance to deformation and aging resistance. The weakness is that it is tough. The famous material made of chinlon is PERTEX and CORDURA.

Corresponding Index for Fiber Material

D: Denir, refers to a unit to measure the density of fiber, which shows the grams in every 9,000 meters’ fiber (the lower the denier is, the thinner the fiber is.)Formula is D=G/L*9000, which means fiber weight/fiber length*9000. The commly material strength index used for backpacks are 450D and 500D. The material higher than 500D is used for the easily abrading parts like the bottom of backpacks.

T: Tex is short for “T”, a unit to measure the density of fiber, which shows the weight in the  convention moisture regain of 1000 meter’ fiber or yarn. Formula is T=G/L*1000, which is fiberi weight/fiber length*1000.

TX=shrink processing   RS=tearing resistance    N=Nylon   P=Polyester Fiber

TXN1000: a strong wearable material, used for the easily abraded parts of hiking bags

TXN500: a material made of shrinkage tissue of nylon fiber, used for light hiking backpack.

RSN500 GRID: a fabric which is pleated by TXN500 and black tearing resistance fiber.

RSN 500: nylon fiber as its pleating material, made into a RS fabric.

TXP900: made of 900D fabric, used for the easily abraded parts of small and medium sized hiking backpacks.

TXP600: polyester fiber fabric, with an excellent touch and quality.

RSP600: Reformed from TXP600, with tearing resistance fiber tissue.

SRN420: small area of nylon fiber fabric, possessing tearing resistance function, used for the surface of technical backpacks to strengthen the fabric and lighten the weight of backpacks.

MNP420: This kind fabric has the texture like metal look.

1680 NYLON: This tough fabric is commonly used in travelling bags.
