Polyester is a fabric commonly used in the field of clothing fabrics. It can be roughly It is divided into two categories: polyester filament and polyester staple fiber. Maybe not many people know the concept of polyester staple fiber or polyester filament. Next, I will introduce to you the concepts of polyester staple fiber and polyester filament, and the differences between them. What’s the difference between them?
What is polyester staple fiber?
Generally speaking, polyester staple fiber can be divided into three categories: large/medium/small chemical fiber;
Large chemical fiber: This is a kind of direct spinning or Polyester staple fiber spun from PET slices is characterized by bright color and strong stability, with relatively few fabric defects.
Medium chemical fiber: What distinguishes it from large chemical fiber The melt direct spinning process is not used, but PET chips or PET recycled materials are used. The price and quality of medium-sized chemical fibers are between large chemical fibers and small chemical fibers. Some factories produce such fibers in large quantities in order to ensure fabric quality and save costs.
Small fiber: it only uses PET regrind The spinning process, the price and quality are relatively low, and it is often used to produce fabrics or accessories (filling) that do not have high quality requirements.
As mentioned above, PET chip spinning is mentioned. The short fibers made by this process are generally defect-free. , and the fiber thickness is relatively uniform, the fabric feels smooth and soft, and its strength is also very good. The small chemical fibers of polyester short yarn are not produced in this way, so its various physical indicators are not only medium chemical fibers and large chemical fibers.
What is the difference between polyester staple fiber and polyester filament?
1. The long polyester staple fiber heel is the first The difference is the length. The length of short fiber is generally within 10 centimeters, while the length of filament starts at one thousand meters.
2. Then there are differences in their characteristics. , short fiber is usually blended with natural fibers such as cotton and linen. It will have the characteristics of cotton and linen, while the surface of the fabric made of filament will be brighter and smoother.
3. There are also differences in classification, polyester staple fiber There are two main types: wool and cotton, while filament can be divided into three categories (POY, FDY, DTY).
4. Polyester filament is usually continuous and short Fiber is made by cutting filaments.
