Cold pad-batch dyeing device for open-width knitted fabrics

Abstract

The invention discloses a cold pad-batch dyeing device for open-width knitted fabrics, which comprises a frame, a cloth feeding device and a dyeing padding liquid device, and further comprises a wet supported cloth conveying device, a rollup device and a control circuit. The cloth feeding device, the dyeing padding liquid device and the wet supported cloth conveying device are arranged on the frame one after another; the cloth feeding device, the dyeing padding liquid device and the wet supported cloth conveying device are all provided with mechanical open-width components, and the open-widthknitted fabrics are subject to open-width flattening before entering the units described above; the control circuit controls the rotating speed of electric motors in an active manner so that the cloth feeding device, the dyeing padding liquid device, the wet supported cloth conveying device and the rollup device realize the conveyance of the open-width knitted fabrics under bearable tension in a manner of synchronous operation, the open-width knitted fabrics are free from crumpling and curling in the entire treatment process, and eventually, the open-width knitted fabrics are flatly rolled onto a cloth roller in the form of big batch which can be rotatably piled up like woven fabrics, and the dyeing is completed during the rotatable pile-up, which not only reduces various consumptions andsaves cost remarkably, but also improves the quality of the knitted fabrics.

Description

technical field [0001] The invention relates to a fabric dyeing device, in particular to a dyeing device for open-width flat knitted fabrics. Background technique [0002] The dyeing of cotton knitted fabrics, because the warp direction of the fabric cannot bear too much tension, has been carried out by rope dyeing equipment and methods, and most of them are dyed by rope liquid flow dyeing machines. Compared with pad dyeing and roll dyeing of woven fabrics Dyeing and dyeing equipment and methods obviously have problems such as high consumption, small production batches, many product quality problems, and low production efficiency. In recent years, with the maturity of the cold pile dyeing process of reactive dyes for woven fabrics, the consumption gap between the two has widened. Chinese patent document CN1505715A discloses a method for continuous dyeing of wide-format knitted fabrics. This method is to pretreat knitted fabrics with an auxiliary agent, so that the fabrics ...

AI Technical Summary

Problems solved by technology

To use this method, the auxiliary agent should be pretreated first, and the auxiliary agent should be removed after dyeing, which not only increases the process and complicates the operation, but also increases the consumption of water, electricity, and steam, resulting in an increase in cost. The dyeing of the pretreated part is not consistent with the color of other parts, resulting in defective cloth
