Abstract
The invention provides a stripping agent for cationic dye dyed acrylic fabric. The stripping agent comprises components in percentage by weight as follows: 40%-50% of high fatty acid salt, 5%-10% of a permeating agent, 10%-15% of a dispersing agent and the balance of water, wherein the high fatty acid salt adopts sodium salt of C16-C18 fatty acid; the permeating agent adopts an anionic surfactant; the dispersing agent adopts one of a polyether nonionic surfactant and polyvinyl alcohol. A stripping method adopting the stripping agent comprises steps as follows: a stripping liquid containing 4-8 g/L of the stripping agent is prepared, and a bath ratio is 1: (20-30); the temperature is increased to 100 DEG C at a speed of 2-3 DEG C/min, and stripping treatment is performed for 20-30 min; the fabric is rinsed completely. With the adoption of the method, the stripping rate can be up to 40%-60%, the fabric after stripping is redyed, the K/S value of the dyed fabric is increased by 5%-10% compared with that of the fabric before stripping, the use quantity of the dye can be reduced, and the economic benefit is increased.
Description
Technical field
The present invention relates to acrylic fibers look loom figured to strip technical field, be specifically related to a kind of stripping agent using the acrylic fibers look loom figured of cationic dyeing, and the stripping method of this stripping agent.
Background technology
During cationic dyeing acrylic fabric, owing to being carry out combining with the form of ionic bond between cation dyes and acrylic fiber, the affinity of dyestuff to fiber is larger, and first dye rate is high, migration property is poor, and the defect such as uneven dyeing, repeatability difference easily appears in its product.Therefore, need often strip to acrylic fibers look flower defective product and redye process.The research of stripping to cation dyes is both at home and abroad less, and on market, special stripping agent also very lacks.The general stripping treatment to cationic dyeing acrylic fabric, all adopts the cationic quaternary ammonium salt compounds of close fibrous type, its shortcoming be strip clean, the problem such as easily cause the dark or repeatability of dyeing poor when redying.For this reason, exploitation is applicable to the stripping agent of cationic dyeing acrylic fabric, strips in time and redyes, retrieve the economic loss of enterprise to substandard products, significant.
Summary of the invention
Technical problem to be solved by this invention is for above prior art, provides a kind of stripping agent using the acrylic fibers look loom figured of cationic dyeing, and the stripping method of this stripping agent.
The technical solution adopted in the present invention is:
A stripping agent for cationic dyeing acrylic fabric, this stripping agent comprises each component of following significant percentage: higher fatty acid salt 40-50%, bleeding agent 5-10%, dispersant 10-15%, surplus are water, and described higher fatty acid salt is C
16-c
18the sodium salt of aliphatic acid, bleeding agent is anion surfactant, and described dispersant is the one in polyether nonionic surfactant, polyvinyl alcohol.
The present invention further provides the stripping method of the stripping agent of above-mentioned cationic dyeing acrylic fabric, specifically comprise the following steps:
(1) after taking each component according to above percentage by weight, preparation stripping agent;
(2) in stripping agent, add water, preparation stripping agent content is the liquid of stripping of 4-8g/L, bath raio 1:(20-30);
(3) put into the acrylic fibers dyeing flower fabric of cationic dyeing, with the ramp to 100 DEG C of 2-3 DEG C/min, stripping treatment 20-30min, then discharges liquid;
(4) use 60-70 DEG C of hot water rinsed clean, then carry out cold rinse, complete and strip.
When the acrylic fibers dyeing flower fabric of described cationic dyeing is light look loom figured, described in strip the content 4-6g/L of stripping agent in liquid, the stripping treatment time is 20-25min; When the acrylic fibers dyeing flower fabric of described cationic dyeing is dark look loom figured, described in strip the content 6-8g/L of stripping agent in liquid, the stripping treatment time is 25-30min.
Operation principle of the present invention is: adopt anion and non-ionic compound to contaminate the stripping agent of acrylic fabric as cation dyes, under the condition of stripping, dissociating of sat linkage between dyestuff and fiber can be accelerated, by the anion of higher fatty acid salt, the cation dyes on acrylic fabric are moved in solution, thus make dyestuff depart from fabric.
Compared with prior art, the present invention has following remarkable advantage and excellent effect: facts have proved, no matter be light look loom figured or dark look loom figured, the rate of stripping can reach 40-60%, and the fabric after stripping is redyed again, and the K/S value of DYED FABRICS improves about 5-10% before stripping, the consumption of dyestuff can be reduced, increase economic efficiency, solve fabric simultaneously after cationic stripping agent is stripped, when redying, cannot again contaminate a dark difficult problem; And there is the extraordinary feature of environmental protection, be suitable for large-scale industrialization and apply.
