Polyester dyeing method

Abstract

The invention discloses a polyester dyeing method. The method comprises the following steps of step one, utilizing a double twisting machine to perform double twisting and spooling processing to formyarn bobbins; step two, utilizing a yarn pressing machine to perform yarn pressing on the yarn bobbins, and pressing and fixing a plurality of yarn bobbins on a yarn loading column; step three, mounting the yarn loading column to which the yarn bobbins in a yarn loading frame, and placing the yarn loading frame into a dyeing cylinder for dyeing by using a lifting device; step four, after the dyeing is completed, taking out the yarn loading frame from the dyeing cylinder by using the lifting device, and dehydrating the yarn bobbins. The polyester dyeing method fixes a plurality of yarn bobbinson the yarn loading column through pressing, the yarn loading column is installed in the yarn load frame for centralized dyeing, the yarn bobbins are evenly distributed, more yarns are stored per volume, thereby saving the amount of dyeing water and saving energy, and the yarn pressing machine is used for improving the degree of automation and mechanization of the dyeing, thereby greatly improvingthe production efficiency.

Description

technical field [0001] The invention belongs to the technical field of dyeing and finishing, in particular to a polyester dyeing method. Background technique [0002] Dyeing and finishing refers to the process of chemically treating textile materials (fibers, yarns and fabrics). It is also commonly known as printing and dyeing in modern times. Dyeing and finishing, together with spinning, weaving or knitting, form the whole process of textile production. Dyeing and finishing includes pretreatment, dyeing, printing and finishing. The quality of dyeing and finishing has an important impact on the use value of textiles. [0003] In the existing dyeing and finishing process, the high-elastic polyester dyeing process is to use bread yarn skein dyeing, and skein dyeing is to fold the fiber yarn in a skein shape and put it in a sarong. In the dyeing machine, pumps or mechanical devices are used. A method of circulating or agitating the dye liquor to obtain an even dyeing. [0004...

AI Technical Summary

Problems solved by technology

[0004] However, the existing dyeing and finishing process mainly uses the hank yarn dyeing machine, the hank yarn dyeing process takes a long time, and for the selected dyeing vat, the single dyeing amount is small and the efficiency is low

In addition, the existing high-elastic yarn dyeing process is automated and has a low degree of mechanization, requiring more labor, and the dyeing and finishing energy consumption is high, and the water consumption and steam consumption are high.
