Abstract

The invention discloses an ultra-low bath ratio terylene cheese fiber dyeing method. The method comprises pre-treatment, dyeing and post-treatment, wherein the bath ratio is 1: 2.5-3, the pre-treatment comprises the following steps: a)changing and screening, adding an auxiliary agent, wherein the auxiliary agent comprises an osmotic agent, a soft water dispersant and glacial acetic acid, directly adding or completely adding the material through one-tine circulation; b) controlling the winding density of polyester fiber cheese between 0.30-0.53 g / dm<3> which can satisfy the high sealing requirement during a circulating dyeing process, wherein the dyeing differential pressure is not lower than 1.0 bar; c) heating the material to the temperature of 80-100 DEG C with rate of 0, operating for 10-30 min and discharging water; and d) after the water is discharged, adding a high temperature levelling agent, a healant and glacial acetic acid, and controlling the pH value at 3.5-5.5. The dyeing method solves the problems of large bath ratio, high cost, and large pollution dissipating energy of the current yarn beam dyeing.

Description

technical field [0001] The invention belongs to the field of textiles, in particular to a method for dyeing polyester cheese cheese fibers with an ultra-low bath ratio. Background technique [0002] Bath ratio is a term used in textile dyeing and finishing, which refers to the ratio of exhaust dyed fabric to dye liquor. Liquor ratio is one of the three elements of the dyeing process. The size of the liquor ratio affects the amount of water used and the amount of fuel and additives. With the increase of the liquor ratio, the consumption of water, steam, electricity, dyes, and additives per ton of yarn How to reasonably control the bath ratio and reduce the bath ratio is one of the main ways to save energy and reduce emissions; the best key to realize energy saving is to reduce the bath ratio is the most direct. [0003] The current application of yarn dyeing technology is divided into two advanced dyeing technologies: cheese dyeing and warp beam dyeing, but the current tradi...
