Problems solved by technology

Polyester fine denier pre-oriented fiber is one of them, also known as POY fiber. The color and luster of polyester fine denier pre-oriented fiber in the prior art is better than that of ordinary fiber. The natural touch and cool feeling improve the waxy feeling of synthetic fiber and increase the The bulkiness and air permeability of the fiber, but there are still the disadvantages of small package density, small capacity, inconsistent hardness, and the occurrence of stacked yarns and uneven quality of the inner and outer layers. Therefore, the present invention is based on the existing technology. A Polyester Fine Denier Porous Flat Fiber

Abstract

The invention relates to the technical field of chemical fiber products, in particular to a dacron fine denier multi-hole flat fiber and a method for producing the dacron fine denier multi-hole flat fiber. The dacron fine denier multi-hole flat fiber comprises a fiber body. The fiber body is provided with 192 strips of monofilament, the cross section of each strip of monofilament is in the shape of a waist, the linear density of the fiber body is 207-253dtex, and the monofilament is evenly and irregularly distributed. The produced dacron fine denier multi-hole flat fiber is beautiful in appearance, good in inherent quality, small in inner-layer and outer-layer fluctuation, stable in tension, soft, long and straight in style, fine and smooth in hand feeling, even in dye absorption, bright-colored in dye, large in package density, high in capacity, consistent in whole package width, uniform in hardness, free of overlapped yarn and even in inner-layer and outer-layer quality, and is a high and new-tech product with high quality and high additional value.

Description

Technical field: [0001] The invention relates to the technical field of chemical fiber products, in particular to a polyester fine-denier porous flat fiber and a production method thereof. Background technique: [0002] With the further development of the chemical fiber industry, the technical and quality requirements of chemical fiber products are getting higher and higher. At the same time, with the continuous improvement of living standards, people's requirements for clothing are no longer satisfied with the basic needs of warmth and comfort. Functionality is imperative. Polyester fine denier pre-oriented fiber is one of them, also known as POY fiber. The color and luster of polyester fine denier pre-oriented fiber in the prior art is better than that of ordinary fiber. The natural touch and cool feeling improve the waxy feeling of synthetic fiber and increase the The bulkiness and air permeability of the fiber, but still have the disadvantages of small package density, ...
