Abstract

The invention discloses a post mercerization alkali resisting pure cotton black yarn dyeing recipe and a preparation method thereof. A moderate-temperature type reactive dye replaces a high-temperature type reactive dye, a reactive black G dye with a vinyl sulfone and monochloro s-triazine MCTVS structure is adopted, the alkali resistance of the reactive black G dye is improved by compared with that of a common moderate-temperature type reactive dye, the reactive black G dye is used as a main dye during dyeing, through the shading of three matched dyes of reactive red S-3B, the reactive yellow TS-3R and reactive dark blue S-G which are good in alkali resistance, a dyeing solution is prepared, dyeing is performed under the condition of a moderate temperature of 60 DEG C, black which is pure and normal in coloured light, fuliginous and bright and has various coloured light can be obtained, and the requirements of customers to color of black yarns can be met. The dyeing solution not only has the effect of resisting high-concentration alkali in post mercerization when being used for dyeing pure cotton yarns, can ensure that dyed yarn after dyeing meets the national standard requirements to alkaline-resisting fastness indexes, but also has the advantages that the dyeing temperature is low, energy consumption is low, and the dyeing cost is lowered greatly.

Description

Textile black yarn dyeing prescription of a kind of post-mercerizing resistant highly basic and preparation method thereof

Technical field

The present invention relates to a kind of dyeing prescription for mercerising colo(u)r streak and preparation method thereof, relate in particular to textile black yarn dyeing prescription of a kind of post-mercerizing resistant highly basic and preparation method thereof.

Background technology

Purified cotton high grade yarn through singing, the manufacturing procedure such as mercerising, dyeing, make soyeux beautiful gloss, the crease-resistant high-quality Mercerization dyeing yarn of softness, the knit fabric being made into this yarn, singe, after the operation such as post-mercerizing, softness processes, become high-grade textile mercerising fabric through secondary again.This " mariages is two to be burnt " textile mercerising fabric, has not only retained the good natural characteristic of raw cotton fiber completely, and has had soyeux gloss, soft feel, good sucting wet air permeability, plentiful elasticity and drapability; Add that pattern is abundant, wear comfortable and random, fully demonstrated wearer's makings and grade.Along with improving constantly of people's living standard, people will be more fastidious to wearing cultural pursuit, and so the market prospects of mercerized cotton fabric are very optimistic.Because the fabric being made into through this dyed yarn will be through post-mercerizing processing, so the dyestuff on dyed yarn must be able to tolerate the effect of post-mercerizing highly basic.

So-called " post-mercerizing resistant highly basic pure cotton dyeing yarn " refers to that the purified cotton yarns after dyeing becomes after fabric through weaving, the highly basic effect of the dyestuff energy post-mercerizing resistant processing on fabric, and mercerising concentration of lye is 280g/L.Yarn dyeing factory, in the time that post-mercerizing resistant highly basic purified cotton yarns is dyeed, is all to select High Temperature Type Reactive Dyes both at home and abroad, and as domestic KE type, Taiwan is light H-E type and external De Sida Procion H-EXL type dye forever.Because the design feature of such dyestuff is most active groups for two chloro-s-triazine structures, determined that it is alkaline-resisting, but promote rate variance, dye-uptake is low.And current all dyestuff manufacturer is all without the black dyes of the type, dyeing enterprise adopts high temperature modification Huang, dark blue, red colorant match, dye dosage is large, more than dyestuff weighs 10% owf to fabric, add because its dye-uptake is low, dyestuff content and COD value is high, wastewater treatment difficulty is large in waste liquid after dyeing; Dyeing temperature is higher is 80 DEG C, and energy resource consumption is large, so dyeing cost is high.And although general traditional middle warm type reactive black dye enhancing rate is good, dye-uptake is high, dyeing temperature lower is 60 DEG C, but because it is to be formed by C.I. 5 black of two vinyl sulfone(RemzaolHuo Xingranliaohuoxingjituan) active group structures and the orange blending of C.I. 82 that contains dichloro s-triazine active group structure mostly, it is not alkaline-resisting, so the fabric being made into by the textile black yarn of the type reactive dyeing can not the processing of post-mercerizing resistant highly basic.

Summary of the invention

Technical problem to be solved by this invention is just to provide textile black yarn dyeing prescription of a kind of post-mercerizing resistant highly basic and preparation method thereof, when this dyeing prescription dyes for purified cotton yarns, high concentration highly basic effect that not only can post-mercerizing resistant processing, the alkali fastness index of the dyed yarn requirement that is up to state standards after dyeing; And dyeing temperature is low, energy resource consumption is little, greatly reduces dyeing cost.

In order to solve the problems of the technologies described above, the technical solution that textile black yarn dyeing prescription of a kind of post-mercerizing resistant highly basic of the present invention and preparation method thereof adopts is such:

A textile black yarn dyeing prescription for post-mercerizing resistant highly basic, comprises the active black G dye of 3 ~ 8% owf; Any 0 ~ 2 kind of dyestuff in 0 ~ 1% owf active red S-3B dyestuff, 0 ~ 1% owf active yellow TS-3R dyestuff, 0 ~ 1% owf reactive navy blue S-G dyestuff.

The preparation method of described dyeing prescription is as follows: using active 3 ~ 8% owf black G dye as main dyestuff, evenly mix and be made into staining solution with any 0 ~ 2 kind of dyestuff in 0 ~ 1% owf active red S-3B dyestuff, 0 ~ 1% owf active yellow TS-3R dyestuff, 0 ~ 1% owf reactive navy blue S-G dyestuff, dye bath ratio is 1:8 ~ 1:30.

Above-mentioned active black G dye, active red S-3B dyestuff, active yellow TS-3R dyestuff, reactive navy blue S-G dyestuff are all produced by Huntsman Corporation.

Adopt after technique scheme, due to textile black yarn dyeing prescription of a kind of post-mercerizing resistant highly basic of the present invention and preparation method thereof, by middle Resist Reactive Dyes replacement High Temperature Type Reactive Dyes, what adopt is the active black G dye with vinyl sulfone(RemzaolHuo Xingranliaohuoxingjituan) and a chloro-s-triazine isodigeranyl active group structure, during alkaline resistance properties is general, Resist Reactive Dyes increases, main dyestuff while setting it as dyeing, through the active red S-3B good with supporting alkaline resistance properties, tri-kinds of dyestuffs of active yellow TS-3R and reactive navy blue S-G are adjusted coloured light, be made into staining solution, under 60 DEG C of conditions of middle temperature, dye, can obtain the black of the pure pitch-black beautiful various coloured light of coloured light, can meet the color requirement of client to black yarn.

This dye liquor is for purified cotton yarns when dyeing, high concentration highly basic effect that not only can post-mercerizing resistant processing, the alkali fastness index of the dyed yarn requirement that is up to state standards after dyeing; And dyeing temperature is low, energy resource consumption is little, greatly reduces dyeing cost.
