Abstract

The invention discloses a terylene/cotton/chinlon/spandex polycomponent seamless underwear dyeing process, which belongs to the technical field of pretreatment, dyeing and afterfinish processes of knitgoods. The process comprises the following steps: performing oxygen bleaching refining on cotton and refining oil removal on terylene/cotton/chinlon/spandex according to the prior oxygen bleaching refining and oil removing technological requirements; respectively adding various dyes and auxiliary agents to perform one-bath dyeing on the terylene/the cotton/the chinlon/the spandex; and finally performing softening treatment according to the prior softening treatment technological requirements, wherein the dyes and the auxiliary agents consist of a dispersing dye, a high-temperature neutral fixing reactive dye, a weak acidic or neutral dye, a chelating dispersant, sodium sulfate, a disperse leveling agent, a pH regulator P-7 and the like. The process reasonably selects the low-temperature dispersing dye and the high-temperature neutral fixing reactive dye, adopts one-bath process for dyeing, shortens the process flow and the dyeing time, reduces the using amount of steam and water, reduces pollution discharge, improves the production efficiency, and reduces the dyeing cost.

Description

Terylene/cotton/chinlon/spandex polycomponent seamless underwear dyeing
Technical field
The present invention relates to a kind of terylene/cotton/chinlon/spandex polycomponent seamless underwear dyeing, belong to pre-treatment, dyeing, the postfinishing process technical field of knitwear.
Background technology
The dyeing of existing terylene/cotton/chinlon/spandex polycomponent seamless underwear is mainly the dyeing of three bath methods, promptly dye terylene, dye cotton, dye polyamide fibre three baths, the technological process of its dyeing is: cotton oxygen floats refining oil removing → hot water wash → wash → dye terylene → hot water wash → reduction cleaning → hot water wash → wash → dye cotton → hot water wash → soap → wash → dye chinlon/spandex → hot water wash → washing → soft treatment etc.Existing technology mainly exist technology and dyeing time long, damage problems such as product, color instability, water consumption, power consumption, blowdown flow rate are big easily.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can effectively shorten dyeing, enhance productivity, reduce the terylene/cotton/chinlon/spandex polycomponent seamless underwear dyeing of blowdown.
The present invention is terylene/cotton/chinlon/spandex polycomponent seamless underwear dyeing, it is characterized in that being undertaken by following processing step:
A, oxygen float the refining oil removing: with existing technology, terylene/cotton/chinlon/spandex polycomponent seamless underwear is put into dye vat, carry out the refining oil removing that cotton oxygen floats refining, terylene/cotton/chinlon/spandex by the technological requirement that existing oxygen floats the refining oil removing, then through hot water wash, washing;
B, dye terylene/cotton/chinlon/spandex: add various dying material and auxiliary agent respectively and carry out dying terylene/cotton/chinlon/spandex,, soap, wash then through hot water wash with bathing with bathing;
C, soft treatment: carry out soft treatment by existing soft treatment technological requirement;
Dying material among the described step B and auxiliary agent be by DISPERSE DYES, the neutral fixation REACTIVE DYES of high temperature, and faintly acid or neutral dye, chelated dispersants, Kayaku Buffer P-7) glauber salt disperses levelling agent, pH value conditioning agent P-7 (English name: composition such as.
The addition of dying material and auxiliary agent can be respectively among the described step B: chelated dispersants 0.3~0.8g/L, pH value conditioning agent P-70.5~1g/L disperses levelling agent 0.25~1g/L, glauber salt 5~20g/L.
The neutral fixation REACTIVE DYES of described high temperature can be CN type REACTIVE DYES or NF type REACTIVE DYES or L type REACTIVE DYES.
Described DISPERSE DYES can be the low form DISPERSE DYES.
Described bath is together dyed terylene/cotton/chinlon/spandex and can be carried out according to the following steps: adding assistant in the time of 30 ± 5 ℃, the order of adding assistant is chelated dispersants, disperses levelling agent, pH value conditioning agent P-7, glauber salt, adds to add another kind of auxiliary agent again after changeing 2-3min behind a kind of auxiliary agent; Add weak acid dye or neutral dye after all auxiliary agents all add and change 3~8min, add again and disperse dyestuff to change 3~8min, be warmed up to 50 ± 5 ℃ with 1~1.5 ℃/min and add the neutral fixation REACTIVE DYES commentaries on classics of high temperature 3~8min, be warmed up to 113 ± 3 ℃ of insulation 60 ± 5min with 1~1.5 ℃/min, cool to 80 ℃ again to sample, cool to 60 ℃ of drainings at last.
The present invention compared with prior art has following outstanding advantage and good effect:
1, dyeing with three bath methods originally, dyes, shortened technological process, shortened dyeing time, reduced the consumption of steam and water, reduced blowdown, improved production efficiency, reduced the dyeing cost by process modification and innovation back single bath process.
2, according to dying terylene, dye cotton, dye the dyeing requirement of chinlon/spandex single bath process, in the required DISPERSE DYES of prior art, REACTIVE DYES, faintly acid or neutral dye, chelated dispersants, disperse levelling agent, on the basis of dying such as glauber salt material and auxiliary agent, through repeatedly repetition test comparison, rationally select the low form DISPERSE DYES for use, the neutral fixation REACTIVE DYES of high temperature and part faintly acid or neutral dye, saved acid levelling agent, glacial acetic acid, sodium acetate, auxiliary agents such as soda ash, added pH value conditioning agent P-7, make dye bath remain on neutrallty condition, thereby make one-bath dyeing processing technology energy smooth implementation.
3, according to the requirement of terylene/cotton/chinlon/spandex co-bathing dyeing and dying material and auxiliary agent to technology, through repeatedly repetition test comparison, rationally determine the interpolation order of dying material and auxiliary agent and temperature, time, prevent between each dyestuff, the auxiliary agent, interaction between dyestuff and the auxiliary agent, help stablizing dyeing, improve the once successful probability of dyeing.
