Abstract

The invention discloses a porous ultrafine X-shaped polyester fiber and a preparation method of the porous ultrafine X-shaped polyester fiber. According to the porous ultrafine X-shaped polyester fiber, a spinning micropore structure of a spinning jet is in a shape of symmetric X blades; an obtuse angle ranges from100 to 110 degrees, and the length-width ratio of the blade is 5 to 8: 1; a cooling formation technology is the combination of annealing and cross air blow cooling; a first hot roll temperature under a thermal forming technology is at 88 to 92 DEG C, and a second hot roll temperature is at 125 to 130 DEG C, and the coiling is carried out at a speed of 3800 to 4200m / min. The fiber prepared by the preparation method provided by the invention is high in profile degree, and different fine groove capillary shapes are formed on the section; high porosity among the fibers is ensured, and the fibers are light in weight; the humidity conductivity and humidity absorbing performance of the fibers are effectively improved, and the water retaining performance and air permeability are effectively improved as well; and meanwhile, the fiber and fabric manufactured by the fiber have good effect of dyeing, and are easily dyed, and have the characteristics of being full in color and bright in gloss; and the fabric touches fluffy and elastic.

Description

Technical field [0001] The present invention involves an alien polyester fiber and its preparation method, especially for a porous polyiter polyester fiber and its manufacturing method with different fine grooves. Background technique [0002] Synthetic fiber is usually a round -pore -shaped fiber. Its internal structure is solid structure, with tight arrangement, poor hygroscopic, and infection, and the light is easy to form a long reflection when the light is illuminated on the surface. Therefore, the comfort of the fabric is not goodIt is difficult to meet people's needs.At present, there are many cross -section of alien fibers that have been industrialized. The main manufacturing methods are: mucous polymer melts transform into fine flows with a certain cross -section through the spray holes of a specific shape.The alien section fiber of the fixed section has a larger part of the alien cross -section fiber than the surface area. Its fabric is fluffy and warm, and has some spe...
