Special dyeing tube for chemical fiber silk

Abstract

The invention discloses a special dyeing tube for a chemical fiber silk, comprising: a tube, a tension central spindle, a tension sleeve and a locking tension sleeve, wherein the tube is formed by combining more than three split tubes; the tension sleeve is mutually matched with one end of the tension central spindle; and the locking tension sleeve is mutually matched with the other end of the tension central spindle. The invention has the advantages that: the special dyeing tube has a simple structure and a very high economic benefit when applied to the practical production, and is convenient to assemble and operate, and available for small scale production and large scale production; a tightly wound silk can be directly and conveniently loosened from the inside to meet the loosening requirement before dyeing by taking the special dyeing tube for the chemical fiber silk as a rolling central spindle; besides, any ordinary loose rewinding and other procedures are not needed; and the produced color silk has better silk strength and color uniformity when compared with the foreign like product.

Description

technical field [0001] The invention relates to a dyeing bobbin, in particular to a special dyeing bobbin for chemical fiber. Background technique [0002] Although my country is the largest chemical fiber producer in the world, due to the single variety (the proportion of differential chemical fiber is less than 20%), it lacks competitiveness in the domestic and foreign markets, and it is difficult to meet the development needs of the textile industry. my country imports a large number of various chemical fibers and products every year, and 60% of the chemical fiber fabrics used in export clothing are settled by imports. High-quality chemical fiber dyed yarn has always been dependent on imports, and the high price has seriously restricted the development of the next process and the development of new varieties of fabrics. [0003] The existing domestic colored silk dyeing process still mainly adopts the traditional process method, which is poured onto the dyeing bobbin thr...
