In the production of non-woven fabrics, what is the difference between large chemical fiber, medium chemical fiber and small chemical fiber? How do you distinguish it?

Large chemical fiber: CHEMICAL FIBER
Short fiber with PET slicing or melt direct spinning, features good color, large batch number, strong stability, less defects and good spinnability.

Small chemical fiber: SMALL CHEMICAL FIBER
With PET reclaimed spinning, the price and quality are uneven, suitable for national conditions, and exported to some markets and fields where the quality requirements are not too high (such as fillers, etc.)

Same point:

“Big chemical fiber”, “Chinese chemical fiber” and “small chemical fiber”

First of all, this is a popular saying in the market, not necessarily an accurate definition.

All three are for polyester staple fiber (polyester staple fiber), and other chemical fiber products are not included yet.

The difference is:

simply put:

“Large chemical fiber” Generally, large-scale chemical fiber enterprises use the better quality slice to directly produce the fiber. The process is relatively advanced, and the equipment is mostly imported. The product quality index is ideal, stable, and the spinnability is relatively high.

On the contrary, many small chemical fibers in the market are mixed with Coke bottles and other recycled raw materials in the production. At the same time, the process is relatively backward, the equipment is mostly made in China, and the fiber quality is obviously affected, but the cost is much lower than that of the large chemical fiber, and some quality requirements. Non-high yarns can be mixed with some small chemical fibers.

1. "Dahua Fiber" product refers to polyester staple fiber spun by relatively straight-line imported and domestic production equipment, using polyester melt direct spinning method or polyester chip indirect spinning method. Since the raw materials used in the “Da Chemical Fiber” products are basically qualified grades, the quality indicators of their regular products are superior. “Dahua Fiber” polyester staple fiber is the leading raw material in the cotton textile industry. The “big chemical fiber” production equipment is a device that eats “fine grain”.

2. The vast majority of the production equipment of “Zhonghua Fiber” products and “small chemical fiber” products are produced by domestic small chemical fiber machinery factory. This kind of production equipment has a large distance from the production equipment used by “Da Chemical Fiber” in terms of scale and quality. Therefore, the products produced by using such equipment and the products produced by “Da Chemical Fiber” are also obvious. Quality difference.

Because of this, the “Zhonghua Fiber” and “Small Chemical Fiber” equipment generally use the outer polyester chip and the treated polyester bottle flakes and bubble materials as raw materials for the polyester staple fiber. “China Chemical Fiber” and “Small Chemical Fiber” production equipment are equipment for eating “coarse grains”.

3. The equipment used in "Chinese Chemical Fiber" and "Small Chemical Fiber" is basically the same.

The main difference between them is that “China Chemical Fiber” generally uses external products produced by regular polyester chip production plants and well-processed foreign imported polyester recycled bottles.

The raw materials used in "small chemical fiber" are basically recycled polyester bottle flakes, polyester recycled waste silk and waste materials, and polyester foam materials.

Due to the difference in investment in production equipment, the difference in raw material prices and the difference in product quality, from the current price, under normal circumstances, the difference between “Dahua Fiber” polyester staple fiber products and “Zhonghua Fiber” polyester staple fiber products is 2,000 yuan/ About ton, "Zhonghua Fiber" polyester staple fiber products and "small chemical fiber" polyester staple fiber products differ by 1,000 yuan / ton.

Product Usage

The "large chemical fiber" product has a wide application range.

The “Zhonghua Fiber” product can replace the “large chemical fiber” product in some applications, thus providing a larger profit margin for downstream products.

"Small chemical fiber" products are generally used in areas where the quality of short fibers is not high, and products with lower grades (thicker yarns, sprayed cotton and filler materials than 30s).

“Zhonghua Fiber” and “Small Chemical Fiber” polyester staple fiber products have relatively low investment in raw materials, relatively low raw material prices, and can replace “large chemical fiber” products in some application fields, thus having a large profit margin and being deeply downstream.
