When I first came into contact with the textile industry, I was often told “big chemical fiber”, “medium chemical fiber” and “small chemical fiber” by master craftsmen. In the end, I only remembered the word “chemical fiber”. But what are the differences between them?
Today we will take a look at large chemical fiber, medium chemical fiber and small chemical fiber. I believe you will understand after reading this article.
The first thing to make clear is that “large chemical fiber”, “medium chemical fiber” and “small chemical fiber” are all for polyester short fiber (polyester short fiber) fiber), other types of chemical fiber products are not included yet.
“Big chemical fiber” products refer to relatively sophisticated imported and domestic production equipment, using polyester melt direct spinning method or polyester chips Polyester staple fiber spun by indirect spinning method.
Since the raw materials used in “Da Chemical Fiber” products are basically qualified grade products, the quality indicators of its regular products are all superior, and Da Chemical Fiber Chemical fiber polyester staple fiber is the leading raw material in the cotton textile industry.
“Big chemical fiber” production equipment is equipment that eats “fine grains”. “Medium chemical fiber” products and “small chemical fiber” The vast majority of equipment used in the production of chemical fiber products is produced by small domestic chemical fiber machinery factories.
This type of production equipment is comparable to that of “chemical fiber” products in terms of scale and quality. The production equipment used by “Big Chemical Fiber” is far away from each other, so there is an obvious quality difference between the products produced by this type of equipment and the products produced by “Big Chemical Fiber”.
Because of this, “medium chemical fiber” and “small chemical fiber” equipment generally use out-of-class polyester chips and recycled and processed polyester bottle flakes and foam materials as raw materials for polyester short fiber.
The production equipment of “medium chemical fiber” and “small chemical fiber” are “coarse grain” equipment, which means that the equipment used is basically the same.
The main difference between them is that “Chinese chemical fiber” generally uses foreign products produced by regular polyester chip manufacturers and well-processed foreign imports. Polyester recycled bottle flakes.
The raw materials used by “Small Chemical Fiber” are basically general recycled polyester bottle flakes, polyester recycled waste silk and scrap, and polyester foam materials Etc.
In terms of product uses, “Big Chemical Fiber” products have a wider range of applications; “Zhong Chemical Fiber” products can replace “Big Chemical Fiber” in some applications “product use, thereby providing larger profit margins for downstream products; “small chemical fiber” products are generally used in fields that do not require high quality of short fibers, and produce relatively low-grade products (those thicker than 30s, spray-coated cotton and filling materials, etc.).
