Abstract

The invention relates to a colored profiled polyester multifilament fiber with stable dimension and a preparation method thereof. The preparation method comprises the following steps: adjusting contents of polyester, pigment masterbatch and an additive in a fusant according to a certain proportion, drying and dehydrating, forming after melting, extrusion, spinning and cooling, and obtaining finished filament after oiling, coiling, heating, tensioning, heat setting, inspection and grading. The fiber can be prepared with conventional spinning equipment, has even multifilament bundle yarn and even color distribution, can be widely applied to fields of clothing, decoration and industry. Fabric is smooth, is characterized by soft luster, high breaking strength and low breaking elongation, can ensure stable geometric dimension of the fabric without easy deformation; and the fiber has the advantages of good fabric elastic resilience, less creep and relaxation and low boiling water shrinkage,and can improve the stability due to hard deformation at high temperature.

Description

【Technical field】

[0001] The invention relates to the field of fiber technology, in particular to a non-colored and dimensionally stable polyester multifilament fiber applied to civilian textiles and a preparation method thereof. 【Background technique】

[0002] Since the advent of polyester in the 1950s, great progress has been made in the development of industrial applications. Due to its low heat shrinkage, polyester industrial yarn is widely used in the field of narrow-width fabrics such as filter cloth, sunshade cloth, tarpaulin, etc. The dry heat shrinkage of traditional low-shrinkage polyester industrial yarn is about 2 % or so, the polyester industrial yarn with this level of dry heat shrinkage is woven into cloth. After the coating heat treatment, the cloth surface shrinkage rate is large, the shrinkage is uneven, and the cloth surface is easy to cause unevenness, so it can only be used for narrow fabrics. Weaving. In recent years, due to the rapid development of m...
