Problems solved by technology

However, the preparation of special-shaped fibers not only involves the design of the spinneret, but also the special flow form of the melt in the special-shaped cross-section will also affect the mechanical properties of the fibers. It will cause the friction force to increase when the tow and the wire guide plate are in contact, and it is easy to produce cobwebs, concave-convex yarns and uneven finished yarns

Abstract

The invention relates to a black polyester fiber. The components of the black polyester fiber include a semi-dull polyester slice and a black polyester masterbatch, wherein the weight ratio of the semi-dull polyester slice to the black polyester masterbatch is (80-75):(20-25); the components of the black polyester masterbatch include the semi-dull polyester slice, a black masterbatch and a lustre-enhancing agent, wherein the black masterbatch accounts for 1%-10% of the weight of the black polyester fiber, and the lustre-enhancing agent accounts for 1%-3% of the weight of the black polyester fiber. The preparation method comprises the following steps: (1) blending the semi-dull polyester slice, the black masterbatch and the lustre-enhancing agent, and preparing to obtain the black polyester masterbatch; (2) blending the black polyester masterbatch and the semi-dull polyester slice, and finally spinning to obtain the black polyester fiber. The preparation method disclosed by the invention has the advantages of simple process and low cost; the obtained black polyester fiber has the advantages of good lustrousness, high color saturation and brighter appearance of a made fabric and higher application value in a clothing industry.

Description

technical field [0001] The invention belongs to the field of colored polyester, in particular to a black polyester fiber and a preparation method thereof. Background technique [0002] Due to the inherent structure of polyester, the production and development of colored polyester yarn has always been a thorny issue. In order to meet the national sustainable development strategy and environmental protection requirements, it is urgent to develop technical research on pre-spun dyeing and spinning colored fibers. In recent years, the development of colored polyester yarns has become more and more extensive. The survey shows that black is the most popular color requirement for formal clothing, and the requirements for black are jet black, bright and deep. The glossy polyester fibers currently produced are poor in comfort and softness. The outer surface of the filaments has poor refraction and reflection effects on light, the luster is dim, and there are many hairs, which are eas...
