example 1

[0056] Example 1 Dyeing cotton knit fabric with ultra-short fast dyeing and fixation technology with reactive dyes

[0057] In an old-fashioned Taiwan Heyi four-window U-shaped cylinder, there are 305Kg pre-treated small circular knitting machines 32 S Knitted cotton jersey ready to be dyed a bright red. The number of pieces is: gray cloth / auxiliary material: 24 / 7; a certain dye 150% SF-3B red 33.15g / kg, 150% SF-3R yellow 17.96g / kg, yuanming powder 600g / kg, (180Kg in total) ), Accelerator: 37.5g / kg (11.5Kg in total). Now with reference to claim 2.1 method and description attached figure 1 The technical process, the specific operation is:

[0058] Add cold water to the vat, the bath ratio is about 10; turn on the main pump and other normal operations; the dye is melted in a small bucket in advance and then poured into the chemical vat, the return water is appropriate, and the steam is heated to an appropriate temperature until the dye is completely dissolved. Add it to the ...

example 2

[0059] Example 2 Dyeing cotton jersey with reactive dye pretreatment / dyeing one-bath method ultra-short fast dyeing fixation process technology

[0060] Completely follow the materials, feeding and operation steps and procedures of Example 1, but the dyed object is replaced by the same specification rough cloth without any pretreatment; the amount of red and yellow dyes is properly adjusted, and the amount is reduced; Self-made one-bath auxiliaries containing appropriate amount of pectinase, protease, amylase, other related enzymes, related coenzymes, surface or additives, stabilizers, functional additives, etc.; when adding softener in post-treatment, reduce the amount appropriately. The obtained result is the same as Example 1, but the hand feeling is softer and fuller; there is no obvious cottonseed hull trace. The saving situation is more than 30 tons of water than example 1, more than 1.5 tons of steam, more than 150 degrees of electricity, and time saving of 2 to 3 hours...

example 3

[0061] Example 3 Dye cotton knit rib jersey with reactive dye pretreatment / dyeing / enzyme polishing one-bath method ultra-short fast dyeing and fixation process technology

[0062] Completely follow the materials, feeding and operation steps and procedures of Example 1, but the dyed object is replaced by a certain specification rib blank cloth without any pretreatment; the amount of red and yellow dyes is properly adjusted, and the amount is reduced; Self-made one-bath additives containing appropriate amount of pectinase, protease, amylase, certain type of cellulase, other related enzymes, coenzymes, surface or property agents, stabilizers, functional additives, etc.; , reduce the amount appropriately. The obtained result is the same as Example 1; the cloth surface has better luster and softer hand feeling; there is no obvious cottonseed husk trace. It takes less than 5 and a half hours; the energy saving and emission reduction is greater than that of Example 2.

Abstract

The invention relates to a reactive dye ultra-short rapid dyeing and fixation technology method. The method is realized by effectively minimizing auxiliary time such as feeding, shortening and optimizing post-processing processes, especially carrying soap boiling (one bath color mending) only once in advance to the greatest extend, merging washing, using less hot water and controlling the use of water aiming at various substances to be dyed according to dyeing requirements and the conditions of normal or abnormal and with the help of various accessory ingredients, thereby the reactive dye normal or abnormal dyeing conditions (especially mediate high color with a dye usage higher than 1percent of o. W. f) by the single one bath process, the multifunction composite one bath process, or the like, comprising pre-processing, dyeing, polishing with enzyme, and color mending, and even the pre-processing and the whole dyeing procedure in conventional equipment in an ultra-low bath ratio limit state can be completed well within 2.5-8h. The effects of thorough energy saving and emission reduction, efficiency increasing and consumption reduction, cleaner production and environmental protection are achieved.

Description

technical field [0001] The invention relates to a technical method for ultra-short rapid dyeing and fixation of reactive dyes in the dyeing and finishing industry. After understanding the chemical environment provided by a reasonable dyeing process and the matching of corresponding auxiliaries, the dyeing of reactive dyes (especially medium-dark colors, that is, the industry-recognized dye dosage is above 1% o.w.f, or when the liquor ratio is 1:10 When the amount of dye is more than g / L), the auxiliary time is shortened by adopting low-temperature direct feeding and direct heating method, especially in conjunction with the most critical various ultra-short post-dyeing treatment processes of the present invention, especially soaping in advance ( Soaping, or same-bath color repair, stripping, and pulling) technology, under the premise of fully guaranteeing the quality, the dyeing process except pretreatment or the pretreatment / dyeing one-bath process can be completed within 2.5 ...
