Polyester fabric: a kind of chemical fiber clothing fabric widely used in daily life. Its biggest advantage is good wrinkle resistance and shape retention, and it is suitable for making outerwear clothing. Polyester fabric has high strength and elastic recovery. So durable, wrinkle-resistant, non-ironing.

Polypropylene fabric: It has the lightest specific gravity among all clothing fibers and can float on the water (specific gravity is about 0.9 1g/cm3), but its strength is very good, so it has been widely used in clothing. It has the characteristics of firmness and durability, crisp appearance and good dimensional stability. Mostly used as military raincoats and mosquito nets.

Two: the price of polypropylene and polyester

Elasticity of polyester: Elasticity is close to wool, and it can be almost completely recovered after 5% ~ 6% elongation. The crease resistance is better than other fibers, that is, the fabric does not wrinkle and has good dimensional stability. The elastic modulus is 22 ~ 14 1cn/dtex, which is 2 ~ 3 times higher than that of nylon.

Strength and elongation of polypropylene fiber: polypropylene fiber has high strength, large elongation, high initial modulus and excellent elasticity. Therefore, polypropylene fiber has good wear resistance. In addition, the wet strength and dry strength of polypropylene fiber are basically the same, which is an ideal material for making fishing nets and cables.

Three: polypropylene and polyester waterproof

Polyester: Good water absorption and wear resistance. Wear resistance is second only to nylon, and nylon has the best wear resistance, which is superior to other natural fibers and synthetic fibers.

Polypropylene: hygroscopicity and dyeability Polypropylene has little hygroscopicity and almost no hygroscopicity, and its moisture regain is close to zero under general atmospheric conditions.

Extended data:

The biggest advantage of density polypropylene fiber is its light weight, and its density is only 0.9 1g/cm3, which is the lightest variety in common chemical fiber, so the polypropylene fiber with the same weight can get a higher coverage area than other fibers. High strength polypropylene fiber has high strength, high elongation, high initial modulus and excellent elasticity. Therefore, polypropylene fiber has good wear resistance. In addition, the wet strength and dry strength of polypropylene fiber are basically the same, which is an ideal material for making fishing nets and cables.

Polyester has good wear resistance. Wear resistance is second only to nylon with the best wear resistance, and superior to other natural fibers and synthetic fibers. Good light resistance. Light resistance is second only to acrylic fiber. The light fastness of polyester fabric is better than acrylic fiber, and its light fastness is better than natural fiber fabric. Especially behind the glass, the sun resistance is very good, almost equal to acrylic fiber.
