Recently, friends often ask me what is the difference between polyester staple fiber and polyester filament. The editor specially sorted out the following information and shared it with you in this section, hoping to help everyone.
The fabric woven from filaments is shiny, smooth to the touch, and similar to nylon; staple fiber is used to blend with other fibers such as cotton.
Polyester filament is a yarn with a length of more than one kilometer, and the filament is wound into a group. Polyester staple fiber is a short fiber of several centimeters to ten centimeters.
Polyester staple fiber is divided into cotton type staple fiber and wool type, such as wool, weaving, etc.; polyester filament yarn can generally be divided into three categories: POY (pre-oriented yarn), FDY (full draft yarn), DTY (low stretch yarn), etc. .
Filament refers to continuous fibers, such as continuous tows ejected from silk and chemical fibers. Usually a dozen or dozens of single filaments are combined and woven together. The fabric has a smooth surface and strong luster. It is often used as a summer fabric. Short fibers refer to fibers with a length of a few millimeters to several tens of millimeters, such as natural fibers such as cotton, wool, and hemp. They can also be made by cutting filaments. Short fibers must undergo a spinning process to twist and cohere between fibers to form a continuous yarn for weaving. Short fiber fabrics have hairiness on the surface, plump and fluffy, and are often used in autumn and winter fabrics.
Characteristics and uses of polyester fiber:
Strength: The strength of polyester fiber is nearly 1 times higher than that of cotton and 3 times higher than that of wool, so the polyester fabric is strong and durable.
Heat resistance: It can be used at 70～1700C, and it has good heat resistance and thermal stability among synthetic fibers.
Elasticity: The elasticity of polyester is close to that of wool, and its wrinkle resistance is better than other fibers. The fabric is not wrinkled and has good line retention.
Abrasion resistance: The abrasion resistance of polyester is second only to nylon and ranks second among synthetic fibers.
Water absorption: Polyester has a low moisture regain rate and good insulation performance, but due to low water absorption, high static electricity generated by friction and poor dyeing performance.
Polyester staple fiber is used as clothing fiber, and its fabric can achieve the effect of no wrinkle and ironing after washing. Polyester is often blended or interwoven with various fibers, such as cotton polyester, wool polyester, etc., and is widely used in various clothing and decorative materials.
