Synchronous setting circular knitting machine and method for producing knitted fabric containing thermoplastic fibers through same

Abstract

The invention provides a synchronous setting circular knitting machine and a method for producing knitted fabric containing thermoplastic fibers through the synchronous setting circular knitting machine. The synchronous setting circular knitting machine comprises a rack, a creel support, a needle cylinder, a dragging coiling device, a control cabinet and a synchronous setting device and is characterized in that the synchronous setting device comprises a heat setting roller which is arranged on the creel support and additionally provided with a lifting device, the heat setting roller is connected with a heat setting roller control cabinet, the heat setting roller is located above a dragging fabric coiling roller in the dragging coiling device and driven by the lifting device to ascend and descend, the axis of the heat setting roller coincides with the axis of the needle cylinder, and the outer diameter of the heat setting roller is smaller than the inner diameter of the needle cylinder. According to the circular knitting machine, fabric knitting and heat setting can be performed at the same time, the synchronous setting device is designed reasonably, the knitted fabric can be evenly and continuously heated, and heat setting efficiency is high; pre-setting of the dyeing and finishing working procedure in the production technology is omitted, the technological process is simplified, production cost of the fabric can be reduced substantially, meanwhile consumption is reduced, and the sales-output ratio of ready-to-wear clothes and the utilization rate of the fabric are improved.

Description

technical field [0001] The invention belongs to the technical field of production technology of knitting machines and knitted fabrics, and in particular relates to a synchronously shaped circular knitting machine and a method for producing knitted fabrics containing thermoplastic fibers. Background technique [0002] During the process of parking, storage and transportation of knitted fabrics containing thermoplastic fibers, the surface of the knitted fabrics is irregular and wrinkled due to various stress extrusions, so most knitted fabrics containing thermoplastic fibers need to be dyed before dyeing. Preformed for good dimensional stability and flat appearance. At present, there are two conventional technological processes for knitted fabrics containing thermoplastic fibers: 1. Weaving→cutting→open width presetting→seaming→dyeing→cutting→open width post-setting, and finally obtain the finished open width knitted fabric; 2. Weaving → cylinder high temperature pre-setting ...

AI Technical Summary

Problems solved by technology

The current technological process has the following defects: Since the pre-setting process is completed on the stenter setting machine or the cylinder high-temperature setting machine in the dyeing and finishing workshop, the equipment investment is large, the process flow is long, the energy consumption is high, and the production cost is high.

Due to the limited expansion of knitted fabrics and the limitation of the internal space of the needle cylinder of the equipment, the rollers continue to heat the fabric when the knitting equipment is shut down, resulting in local over-setting of the knitted fabric (the knitting equipment is frequently shut down due to yarn breakage or other reasons, which One defect seriously affects the quality of the fabric)

The synchronous shaping device disclosed in this invention patent application has no heat insulation device. On the one hand, heat loss reduces the utilization rate of heat energy and increases energy consumption; It has a great influence on the service life of the knitting machine and the quality of the fabric

In addition, the invention patent application does not specifically disclose the production process and shaping process of knitted fabrics containing thermoplastic fibers
