Technique for producing chromonema, yarn

Abstract

A technology for preparing the dyed fibres (including natural fibre, protein fibre, chemical fibre, or artificial fibre), or yarn includes fusing the polyester chips, drawing-spinning to become filaments, preheating, boarding, winding on steel bobbin with dense through holes, and dyeing by putting the bobbin in dyeing machine. Its advantage is high dyeing quality.

Description

technical field [0001] The invention relates to a manufacturing process of dyed silk and yarn. Background technique [0002] Dyed silk and yarn are necessary raw materials for all kinds of yarn-dyed fabrics dyed first and then woven in the textile industry. With the continuous improvement of human clothing level, it is increasingly required that dyed silk and yarn products can be continuously innovated to produce better quality New products with lower cost and faster production speed, but now the delivery cycle for dyed silk and yarn is longer. The production process includes: melting polyester chips made of petrochemical products and spinning them into filaments and yarns The thread is wound on the paper tube after elastic treatment, and then the silk and yarn wound on the paper tube are winded to the conical bobbin by a winding machine to become a loose bobbin. The type bobbin is placed in the dyeing machine for dyeing and dehydration. Even in ...

Problems solved by technology

The winding quality is difficult to control. Although the unwinding machine technology has become more and more sophisticated, the imported machine is expensive and cannot fundamentally solve the winding density and quality problems. Often the inner and outer layers of each bobbin, the two ends of the bobbin , the density of the package is inconsistent with the package, which leads to quality accidents such as color difference between the inside and outside of the dyeing package, color flower, and poor particle quality.

Especially for silk products, too many technological processes will cause wool phenomenon, which directly affects the quality of yarn-dyed high-grade fabrics

Moreover, the loose bobbin is wound into a loose bobbin by a winder, and the weight of a single yarn is limited, resulting in an increase in the dyeing bath ratio and an increase in cost.
