Recently, Zhejiang Shengyuan Chemical Fiber Co., Ltd. has undergone repeated trials and optimization of process conditions, and another ultra-fine denier POY specification of 78dtex/144f (corresponding to DTY specification 50D/144f) has been successfully mass-produced.
This is another ultra-fine new specification after mass production of 107dtex/192f ultra-fine denier POY specifications.
Ultrafine denier is a type of fiber interposed between fine denier and very fine denier;
It is generally considered that a filament having a monofilament fineness ranging from 0.33 dtex ≤ dpf ≤ 0.55 dtex (0.3 D ≤ dpf ≤ 0.5 D) is considered to meet the requirements for ultrafine denier.
This kind of product is mainly suitable for weaving high-density waterproof and breathable fabrics, raising and velvet fabrics, Chun Yafang fabrics, etc. Although the added value of the products is very high, due to the fineness of the monofilaments, there are problems such as excessive breakage and easy hairiness. There is still a certain difficulty in production.
In view of the characteristics of ultra-fine denier, the relevant departments of the 78dtex/144f product development stage adopt the method of controlling variables, and carry out related comparison tests of different process conditions and different types of porcelain parts, and finally combine the spinning conditions and product properties. The aspect factor reference comparison optimizes the optimum production process conditions.
