Method for producing PBT (Polythylene Terephthalate) color point core spun yarns

Abstract

The invention discloses a method for producing PBT (Polythylene Terephthalate) color point core spun yarns. The method comprises the following steps: selecting yarn materials; performing process procedures of the PBT color point core spun yarns; implementing the specific production process. According to the method disclosed by the invention, acrylic fibers serve as raw materials of the points, the color point has rich colors, the color is bright, the stereoscopic impression is excellent, and the price can be saved by 20000 Yuan per tonnage compared with that of common chinlon points. A waterproof agent is diluted according to a ratio and uniformly sprayed onto the points, and the points are dried and roasted at a high temperature, so that the colored point achieves a water-repellent effect, the colored points are prevented from being loosened in the subsequent processing procedure, staining of dyes on the color points is reduced in the dyeing process, the shape and brightness of the color points can be guaranteed, and the quality of the yarns is improved. The PBT serves as the core yarn, viscose cotton serves as an outer packaging material, and the problems that the spandex core-spun yarns are poor in acid resistance and chlorine resistance and have non-ideal dyeing effect are solved. The color point core spun yarns produced by the method disclosed by the invention are excellent in fluffiness and crimpiness and high in elasticity and shape stability and have hand feel of cashmere.

Description

technical field [0001] The invention belongs to the field of yarn production, and in particular relates to a production method of PBT colored dot core-spun yarn. Background technique [0002] With the development and progress of the times, people's pursuit of clothing is becoming more and more fashionable and personalized. Color-dot core-spun yarn came into being under such demand. In the past, the core-spun yarn with colored dots mostly used polyester as the colored dot, spandex filament as the core yarn, and outsourced cotton, hemp and other fibers. Not ideal. Contents of the invention [0003] Purpose of the invention: In order to make the clothing fabric more colorful and have a three-dimensional effect, the invention provides a production method of PBT color dot core-spun yarn. It uses PBT as the core yarn, adding acrylic fibers of different colors to some brocade materials, and then through special spinning treatment to make the colorful color ideas attached to th...
