Large chemical fiber: CHEMICAL FIBER
Short fibers spun with PET slices or direct melt spinning , features: good color, large batch number, stable strength, few defects, and good spinnability.
Small CHEMICAL FIBER: SMALL CHEMICAL FIBER
Spun from PET recycled material, the price and quality vary, suitable for national conditions, and Export to some markets and areas where quality requirements are not too high (such as fillers, etc.).
Same points:
“Big Chemical Fiber”, “Mid Chemical Fiber” ” and “small chemical fiber”
First of all, this is a popular term in the market and does not necessarily have an accurate definition.
The three are all for polyester staple fiber (polyester staple fiber), and other chemical fiber product types are not included yet.
The difference is:
Simply put:
“Big Chemical Fiber” Generally, large-scale chemical fiber companies directly produce fibers from better-quality chips, with relatively advanced technology and mostly imported equipment. The product quality indicators are relatively ideal and stable, and the spinnability is relatively high.
On the contrary, many small chemical fibers currently on the market are mixed with slices made from recycled raw materials such as Coke bottles during production. At the same time, the technology is relatively backward, and the equipment is mostly domestically produced, and the fiber quality is obviously affected. , but the cost is much lower than that of large chemical fibers. Some yarns with low quality requirements can be mixed with some small chemical fibers.
Product Usage:
“Big Chemical Fiber” products have a wide range of applications.
In some applications, “medium chemical fiber” products can replace “large chemical fiber” products, thereby providing larger profit margins for downstream products.
“Small chemical fiber” products are generally used in areas where the quality of short fibers is not high, and the production of lower-grade products (thicker yarn than 30s, spray-coated cotton and filling materials, etc.).
“Medium chemical fiber” and “small chemical fiber” polyester staple fiber products have relatively small investment in equipment and relatively low raw material prices, and they can replace “large chemical fiber” products in some application fields. Therefore, it has a large profit margin and is very popular among downstream product manufacturers. </p
