Abstract
The invention discloses color stripping liquor for dyed chinlon fabrics and a color stripping method. The color stripping method is characterized by including the steps of (1) preparation of the color stripping liquor by preparing 0.5-5g/L of ammonia water, 1-10 g/L of ethylene diamine tetraacetic acid, 2-10g/L of acid leveling agents and water into the color stripping liquor; and (2) color stripping by impregnating the colored chinlon fabrics into the color stripping liquor at the room temperature, then increasing the temperature to 80-100 DEG C with the temperature increase rate of 0.5-2 DEG C per minute, impregnating for 30-60 minutes at the temperature of 80-100 DEG C, taking the fabrics subjected to color stripping out, washing the fabrics for 20 minutes at the temperature of 80-100 DEG C, and finally, washing and drying at the room temperature. By the aid of the color stripping method, more than 90% of dye of the dyed chinlon can be stripped, and the strength of the colored chinlon fabrics is almost undamaged.
Description
Technical field:
The present invention relates to stripping of a kind of nylon dyeing fabric, be specifically related to a kind of strip liquid and stripping method of nylon dyeing fabric.
Background technology:
Nylon fabric is widely used in the garment materials such as down jackets, swimming suit, is well received by consumers owing to have the characteristics such as wear-resisting, that feel is soft.Nylon fabric is generally used ACID DYES, reactive dyeing, it dyes polyamide fibre lovely luster, every fastness excellence with ACID DYES, but in actual production, dye the difficult control of dyeing of nylon fabric with ACID DYES, the temperature of dyeing, pH, heating rate affect larger on dying nylon fabric on the ACID DYES, thereby may cause that aberration, cylinder are poor, not return something for repairs and to cause very large economic loss to enterprise if problematic fabric is not stripped.The patent No. is the Chinese invention patent " stripping finishing method of woolen dyed fabric " of CN 101851870 A, the method that a kind of woolen dyed fabric is stripped is disclosed, although nylon dyeing fabric and woolen dyed fabric all are to use acid dyeing, but nylon fabric is different with the mechanism of acid dyeing with mechanism and the wool fabric of acid dyeing, in addition, because nylon fabric has color fixing process one after dyeing, thereby ACID DYES is more firmly combined with nylon fabric.The nylon dyeing fabric runs into the problem of returning something for repairs in actual production, factory generally all adopts sodium hydrosulfite to strip, and the effect of stripping of its method is relatively poor, and generally the rate of stripping can only reach about 30%.
Have based on this, make the present invention.
Summary of the invention:
A first aspect of the present invention purpose provides a kind of liquid of stripping of nylon dyeing fabric, returns something for repairs and strips in order to solve the fabric that it is poor etc. that the uneven dyeing, the form and aspect that occur behind the acid dyeing nylon fabric have deviation, cylinder.
The technical solution used in the present invention is:
A kind of liquid of stripping of nylon dyeing fabric, it is characterized in that: the described liquid of stripping adopts ammoniacal liquor, ethylenediamine tetra-acetic acid, acid levelling agent and water configuration to form, wherein: the consumption of ammoniacal liquor is 0.5-5g/L, the consumption of ethylenediamine tetra-acetic acid is 1-10 g/L, acid levelling agent is any one of acid levelling agent 741-100%, acid levelling agent FK-450B, acid levelling agent TBW-95, and the consumption of acid levelling agent is 2-10 g/L.
In the liquid of stripping of the present invention:
Ammoniacal liquor: claim that again ammonium hydroxide is the aqueous solution of ammonia, water white transparency and have penetrating odor is water white transparency or little band yellow liquid, and solution is certain alkalescent.Ammoniacal liquor mainly plays the pH value of regulating the liquid of stripping in this strips formula of liquid, making the whole solution of stripping is the alkalescent state, is conducive to destroy the chemical bond between ACID DYES and the nylon fibre.
Ethylenediamine tetra-acetic acid, English name EDTA, white powder, can be dissolved in NaOH, sodium carbonate and the ammonia solution, in this stripping method ethylenediamine tetra-acetic acid can be at a certain temperature in the alkalescent ammonia spirit can with the ACID DYES of nylon fibre reaction in Na+, D-SO3-the complex compound that complex reaction generates ethylenediamine tetra-acetic acid occurs, and reaches the purpose of stripping thereby make ACID DYES break away from nylon fabric fully.
Described acid levelling agent is that 741-100%(Suzhou connection wins chemical Co., Ltd and produces), spin Chemical Manufacture among the FK-450B(), TBW-95(dolantin Chemical Manufacture) any one.This analog assistant is pale yellow to the transparent thick liquid of yellowish-brown, is the non-ionic surface active agent compound, and ACID DYES is had good dispersive property.Can guarantee the uniformity of the process of stripping and again being combined with nylon fibre of ACID DYES.
A second aspect of the present invention purpose provides a kind of stripping method of nylon dyeing fabric, it is characterized in that, may further comprise the steps:
(1) disposes the liquid of stripping: ammoniacal liquor, ethylenediamine tetra-acetic acid, acid levelling agent and water are configured to the liquid of stripping, wherein: the consumption of ammoniacal liquor is 0.5-5g/L, the consumption of ethylenediamine tetra-acetic acid is 1-10 g/L, acid levelling agent is any one of acid levelling agent 741-100%, acid levelling agent FK-450B, acid levelling agent TBW-95, and the consumption of acid levelling agent is 2-10 g/L;
(2) technique of stripping: the colored nylon fabric is at room temperature flooded the liquid of stripping, then be warming up to 80-100 ℃ with per minute 0.5-2 ℃ heating rate, dipping is 30-60 minute under this temperature, then take out fabric after stripping with 80-100 ℃ hot water wash 20 minutes, washing under the last room temperature, oven dry.
