Abstract
The invention discloses a technological process for polyster fibre dyeing, comprising the following concrete steps: melting dyes in 30-40 DEG C warm water to form stable and even dye suspensoids; slowly adding the suspensoids into a dye vat, and then adding glacial acetic acid, carriers, a dispersing agent and water in sequence; controlling the heating rate to be in the range of 0.5-1 DEG C per minute, and rising the temperature to 95-108 DEG C; controlling the working pressure to be in the range of 0.08-0.10MPa, preserving heat for 45-60 minutes, and cooling to below 80 DEG C; and after raffinate is discharged, carrying out reduction clearing. In the technological process, fully-injected micropressure cabinet-type dyeing equipment is used to control the working pressure to be in the range of 0.08-0.10 MPa, thus the polyster dyeing temperature is reduced to 95-108 DEG C from 130-135 DEG C in traditional high-temperature high-pressure dyeing, thereby reducing dyeing bath ratio, decreasing energy consumption of chemicals, water, steam and the like, obviously improving production efficiency, ensuring dyeing quality and lowering pollutant discharge.
Description
Technical field
The present invention relates to a kind of textile printing and dyeing industry field, particularly relate to a kind of process of polyster fibre dyeing.
Background technology
At present, polyster fibre is the output maximum in closing fibre, purposes is the widest, but because terylene is a hydrophobic fibre, the interior molecules structure is quite tight, big molecule lacks polar group, dyestuff be difficult to by fiber directly absorption and on dye, under normal temperature condition, be difficult to carry out dyeing and finishing processing, use the polyester fibre at high temp and pressure decoration method of comparative maturity to be suitable for small lot at present, the production of many kinds, because of its dyeing is spared saturating, color development is bright-coloured pure and obtain domestic and international dyeing extensive use, but in high-temperature pressure dyeing, the high temperature resistant dispersion stabilization of some DISPERSE DYES is poor, and the uneven problem that causes dyeing often occurs, simultaneously because the restriction of device security under high-temperature and high-pressure conditions, dyeing is in batches little; bath raio is big; the labour intensity height; the problem that every consumption is big is very obvious, and this just seriously deviates from the development trend of ecological dyeing.In addition, use at present more terylene disperse dye normal pressure dyeing mainly be by the adding carrier quicken to the expansion of polyster fibre and on dye, thereby reduction dyeing temperature, improve dye uptake, but carrier easily remains on fabric or the fiber, influence the light fastness of azo dispersion dyes, pollute the environment when using simultaneously and poison human body.
Summary of the invention
The objective of the invention is to: the process that a kind of polyster fibre dyeing is provided.
A kind of process of polyster fibre dyeing comprises the steps:
Dyestuff in being 30 ℃～40 ℃ warm water, temperature is changed material, after forming the stabilized uniform dye suspension, slowly add in the dye vat, add glacial acetic acid, carrier, dispersant and water more successively, the control heating rate is in 0.5～1 ℃/min scope, make temperature rise to 95～108 ℃, control operating pressure 0.08～0.10Mpa scope, insulation dyeing 45～60min is cooled to below 80 ℃, behind the residual liquid discharge, carry out reduction cleaning.
Described glacial acetic acid consumption is 0.5～1g/l.
According to dying thing weight meter, described carrier consumption is 1.5～3%o.w.f, and described dispersant dosage is 0.1%o.w.f.
Described carrier is the o-phenyl phenol sodium salt.
Described dispersant is the condensation product of fatty alcohol and oxirane.
Beneficial effect of the present invention is: the present invention is by dropping to 95～108 ℃ to the dyeing terylene temperature from 130～135 ℃ of conventional high-temperature high pressure dyeing, and control operating pressure based on this in 0.08～0.10Mpa scope, thereby reduced bath raio, chemicals, water, the consumption of steam homenergic have been reduced, can significantly improve production efficiency, guarantee dyeing quality, reduce pollutant emission.
