Description
Technical Field
The invention relates to the technical field of textile processing, in particular to a melt direct spinning medium-control curling HOY production process and polyester filament yarns.
Background
With the improvement of living standard and living quality, people have higher and higher requirements on the aspect of wearing clothes, cotton, hemp and common synthetic fiber fabrics cannot meet the increasing requirements of people due to the characteristics and inherent limitations of the fabrics, and especially in the aspects of overcoat clothes and toy plush, people put forward higher requirements, such as soft hand feeling, good drapability, elasticity, dryness, fineness and the like of fabrics.
HOY is a nylon high-orientation yarn, wherein the most representative product of the nylon 6 high-orientation yarn is a new product in recent years, the performance of the nylon 6 high-orientation yarn is similar to that of nylon 6 filament yarn, the fabric has good hand feeling, and the warping efficiency is high. Compared with the pre-oriented yarn, the high-oriented yarn has higher stretching degree, better disorientation degree and good stability. Chinlon 6 is one of common textile fibers, has a series of excellent performances, and is widely applied to various fields of clothing, home textiles, decoration, agriculture, fishery and the like.
The hollow crimp HOY is short for a nylon high-orientation yarn with a cavity in the cross section along the axial direction, and is an important profiled fiber. The voids of the oriented yarns provide still air to increase the warmth retention of the fibers and increase the surface area per unit volume, thereby increasing their bulkiness. The adsorption capacity of the hollow curled HOY to media such as water, gas, blood and the like and the binding capacity of the hollow curled HOY and a matrix material when the hollow curled HOY is used as a composite material are improved to a certain extent, so that the rigidity and the stiffness of the hollow curled HOY are improved, and the bending resistance and the wear resistance of the hollow curled HOY are also improved. Therefore, the hollow crimp HOY becomes a star product in the functional fiber market at the present stage, and has very large market potential and application value.
Currently, the main production method of hollow crimp HOY is the melt spinning method, which is the most common and least costly method. For melt spinning, there are generally two types, a melt direct spinning method and a chip spinning method. The melt direct spinning technology is a method for directly spinning by utilizing polymer melt, and because the melt direct spinning technology has short process flow and low production energy consumption and operation cost, the melt direct spinning is already a main production mode of the current civil silk. However, the method has high requirements on polymerization and spinning stability, the existing process for producing the hollow curled HOY by melt direct spinning is complex, the spinning cost is high, the labor intensity is high, and the comprehensive performance of the prepared product needs to be further improved.
Therefore, the development of a stable and efficient melt direct spinning hollow crimp HOY production process has substantial industrial significance and plays a very important role in promoting the development of the functional textile industry.
