What is polyester staple fiber?
Polyester staple fiber is a fiber obtained by cutting polyester spun tow. Polyester staple fiber has the characteristics of high strength, strong heat resistance, good elasticity, strong wear resistance and low water absorption.
Polyester is widely used to make clothing fabrics and industrial products. It has excellent setting performance and is an important variety of synthetic fiber. It is a fiber polymer made by the exchange and reaction between specific chemical elements, and it is a fiber made by spinning. Polyester is a cheap, durable and non-deformable fabric.
Types of polyester staple fibers
1, "big chemical fiber". This product refers to polyester staple fiber spun by direct spinning of polyester melt or indirect spinning of polyester chips with relatively mature imported and domestic production equipment. Because the raw materials used in "big chemical fiber" products are basically qualified,
Therefore, all the quality indexes of its regular products are excellent. "Big chemical fiber" polyester staple fiber is the leading raw material in cotton textile industry. 2. Most of the production equipment used for "China Chemical Fiber" products and "Small Chemical Fiber" products are produced by domestic small chemical fiber machinery factories. This kind of production equipment is far from the production equipment used by Dahua Fiber in terms of scale and quality.
Therefore, there are obvious quality differences between the products produced by this kind of equipment and those produced by "Big Chemical Fiber". The equipment used by "China Chemical Fiber" and "Small Chemical Fiber" is basically the same. The main difference between them is that "China Chemical Fiber" generally adopts the products produced by foreign regular polyester chip manufacturers and imported polyester recycling bottles after good treatment. The raw materials used in "small chemical fiber" are basically recycled polyester bottles, polyester recycled waste silk and waste, polyester foam and so on.
Polyester staple fiber price
Polyester fabric has many characteristics, the main characteristics are: high strength and elastic recovery, good fastness and durability, poor hygroscopicity, good heat resistance and light resistance, not afraid of mold and moth, and not easy to deform.
Different regions, different manufacturers and different brands have different prices of polyester staple fiber. The general price is about RMB 0/0000 per ton/kloc.
Use of polyester staple fiber
Polyester short sewing thread. Made of 100% polyurethane polyester staple fiber, it has high strength, good elasticity, wear resistance, low shrinkage and good chemical stability. The surface is hairy, resistant to 130 degrees, and dyed at high temperature. Polyester raw material is the most resistant to friction, dry cleaning, stone grinding, bleaching and other detergents among all materials.
Its low elongation and shrinkage are characterized by flexibility, suppleness, full color and good color fastness, which ensures excellent seamability and can prevent wrinkles and needle jumping. Mainly used for industrial sewing of jeans, sportswear, leather products, wool and military uniforms, it is the most widely used and popular sewing thread at present. This is what polyester staple fiber means to you.
I hope it can help consumers.
