Technique for producing polyester filament yarn using false twisting distortion elasticizer

Abstract

The invention relates to a process for manufacturing polyester fiber filament by using a false twisting deformation elastic-adding machine, which is characterized in that raw material strand silk which is from a roller (1) passes through an inlet silk guide (2), then directly passes through a hot box(3) and is heated by the mode of non-contact heating, then moves to a turning silk guide (5), (or passes through a twisting machine 6), then passes through a two-roller (7) and reaches to a network jet nozzle (8) and is manufactured to obtain fully drawn yarn FDY (or shape preserving performances with high requirements such as profile degree, degree of hollowness and the like) polyester fiber filament, The process has the advantages of without altering the device, simple process adjustment and the like, and the switching of the two product processes is flexible and convenient, and the process efficiently extends the using range of the false twisting deformation elastic-adding machine and has obvious economic benefits.

Description

technical field

[0001] The invention relates to a method for producing polyester filaments, in particular to a process for producing polyester filaments using a false-twist texturing machine. Background technique

[0002] Polyester chemical fiber filament is a kind of clothing fabric raw material used in daily life. The biggest advantage of its fabric is that it has good wrinkle resistance and shape retention, and is suitable for outerwear. However, compared with natural fiber fabrics such as cotton, polyester fabrics have poor hygroscopicity, moisture retention and air permeability, and are easy to wear and feel stuffy. With the development of society, chemical fiber technology and people's living standards are improving day by day. The improvement and the improvement of its visual aesthetics are particularly important. Various functional and differentiated products are constantly emerging. The embodiment of the differentiated functionality of most of the products requires...
