Background
The four-side elastic fabric is a fabric which is woven by twisting elastic spandex and yarn together and has excellent elasticity up and down and left and right, has good serviceability, is bred to endow fabric with more excellent wear resistance, and is blended by nylon and spandex.
In order to endow the fabric with different colors, the woven fabric is generally subjected to dye treatment before the fabric is processed into a garment, and nylon and spandex can be dyed by disperse dyes, acid dyes, 1:2 metal complex dyes and other dyes at the temperature of below 100 ℃.
The nylon and the disperse dye are dyed by intermolecular force, but only by the combination of the intermolecular force, so that the dyed fabric has good level-dyeing property and poor deepening property; the nylon and the acid dye are combined through ionic bonds, so that the fabric dyed by the fabric has better brightness, but has the problem of poorer color fastness.
In view of the above-mentioned related art, the inventors consider that nylon four-sided spandex has problems of poor color fastness and poor leveling property during deep color dyeing.
Disclosure of Invention
The application provides a nylon four-way stretch dyeing process in order to improve the degree of dye-uptake of nylon and spandex and improve the color fastness and the level-dyeing property of fabric in the deep color dyeing process.
The nylon four-side elastic dyeing process provided by the application adopts the following technical scheme:
a nylon tetrahedral elastic dyeing process comprises the following steps: s1, pretreating the grey cloth;
s2, presetting: heat setting the pretreated gray fabric for 35-45s at the speed of 25-35m/min at the temperature of 195-210 ℃;
s3, staining: carrying out overflow dyeing on the pre-shaped grey cloth in a dye liquor by a one-bath one-step method under the condition that the pH value is 3-6, wherein the dye liquor comprises 2-2.5% (omf) of 1:2 metal complex dye, 0.5-1.0% (omf) of 1:1 metal complex dye and 0.6-0.8% (omf) of spandex coloring agent;
s4, soaping;
s5, dewatering and scutching;
s6, shaping the finished product;
and S7, rolling the finished product.
By adopting the technical scheme, the situation of uneven tension generated by the chinlon and the spandex in spinning drafting and weaving processing can be eliminated or reduced through presetting, excessive relaxation of the elastic yarn in subsequent processes is improved, and the weft density is increased; in addition, because the chinlon has more terminal amino groups, the 1:1 metal complex dye is easy to combine with the chinlon, and the amino group quantity of the chinlon can be reduced by performing pre-setting at the temperature of 195 plus 210 ℃, so that the isochromatic property of the dye on the chinlon and the spandex is improved, in addition, the 1:2 metal complex dye and the 1:1 metal complex dye have excellent deep dyeing property on the chinlon and the spandex, the dyeing processes of the two dyes are similar, the two dyes have good one-bath adaptability after being compounded, the subsequent one-step one-bath dyeing is facilitated, the active group in a dye solution can be increased by compounding the two dyes, and the brilliance and the color fastness of the dyed fiber are comprehensively improved; the possibility of gathering of the two dyes can be improved by adding the anionic leveling agent, so that the dyes are dispersed more uniformly, the dyeing uniformity of the dye liquor is favorably improved, and when the pH value is 4-6, the dyeing effect of the 1:2 metal complex dye and the 1:1 metal complex dye on the fabric containing the chinlon and the spandex is optimal.
Preferably, the dye solution in S3 is specifically prepared by: adding a chelating dispersant into water, mixing and stirring uniformly to obtain a mixed solution, wherein the mass concentration of the chelating dispersant in the mixed solution is 1.0-1.5g/L, adding 2-2.5% (omf) of 1:2 metal complex dye, 0.5-1.0% (omf) of 1:1 metal complex dye, 1.0-2.0(omf) of anion leveling agent and 1.0-2.0% (omf) of anion leveling agent into the mixed solution, and performing ultrasonic dispersion uniformly to obtain the dye solution.
By adopting the technical scheme, by adding the chelating dispersant, water is dyed, the possibility of combining calcium and magnesium ions with dye negative charge complex ions in common water is reduced, the dye and fibers are fully dyed, the color fastness and the vividness of dyed fabric are improved, and when the mass concentration of chelating dispersion is 1.0-1.5g/L, the complex effect of the chelating dispersion and the two dyes is optimal.
Preferably, the pretreatment of the grey fabric in S1 specifically includes the following steps:
s11, rolling the gray cloth without tension;
s12, pre-shrinking: under the conditions that the temperature is 95-105 ℃ and the water bath ratio is 1 (30-40), the tension-free rolled gray fabric is subjected to heat preservation treatment in a pretreatment liquid for 60-80min at the speed of 40-50 m/min; wherein the pretreatment liquid contains sodium hydroxide and a refining agent;
and S13, multi-stage water washing.
By adopting the technical scheme, as the fabric is treated by adopting the sodium hydroxide, on one hand, dirt and oily substances of the chinlon and the spandex in the spinning process can be removed, and the chinlon and the spandex can not be damaged by the sodium hydroxide, so that on the other hand, the chinlon can be pre-shrunk, and the fabric becomes compact and elastic; because a large amount of organic silicon-containing lubricants are generally used in the weaving process of spandex, the surface of the spandex can be further improved by adding a refining agent, so that the subsequent dyeing is facilitated; and the pre-treatment liquid after the compounding of the sodium hydroxide and the refining agent can comprehensively improve the pre-shrinking effect, so that the dyeing uniformity of the fabric with the dyeing liquid is further improved.
Preferably, the multistage cleaning in S13 specifically includes the following steps:
s131: carrying out primary cleaning on the pre-shrunk grey cloth in S12 at the temperature of 88-95 ℃ by using clear water;
s132: carrying out secondary cleaning on the gray fabric subjected to primary cleaning in the S131 at the temperature of between 75 and 85 ℃ by using clear water;
s133: and (3) carrying out three-stage cleaning on the gray fabric subjected to the second-stage cleaning in the step (S132) at the temperature of 55-65 ℃ by using clean water.
By adopting the technical scheme, the residual pretreatment liquid carried by the pre-shrunk grey cloth can be removed by multi-stage water washing, and the residual pretreatment liquid is prevented from influencing the connection between dye molecules and fibers, so that the color fastness of the fabric is improved; in addition, the fabric is beneficial to further pre-shrinking by washing at different temperatures, so that the flexibility and the hand feeling of the fabric are improved.
Preferably, the dyeing of S3 specifically includes the following steps:
s31, ingrain: at 35-40 ℃ and pH 3-6 with a water bath ratio of 1: (8-12) transferring the grey cloth into the dye liquor;
s32, heating: heating to 55-60 deg.C at 0.3-1.5 deg.C/min, maintaining for 10-15min, heating to 105 deg.C and 110 deg.C at 0.3-1.5 deg.C/min, and maintaining for 65-80 min;
s33, fixation: and adding a color fixing agent for color fixing treatment.
By adopting the technical scheme, the dye dyeing comprises two steps, wherein in the first step, the dye firstly enters the fiber, and the dye entering amount in the fiber can influence the dyeing degree; secondly, dye molecules are subjected to transfer dyeing on the fiber, and the transfer dyeing degree can influence the dyeing depth effect of the fabric; the glass transition temperature of nylon is 47-50 ℃, so if the dyeing temperature is higher than the temperature, the dye quickly enters the nylon fiber, the nylon dyeing is easy to be uneven, and the dyeing temperature is limited, so that the leveling property of nylon and spandex is improved; in addition, the temperature is kept at 55-60 ℃ to be beneficial to uniform dyeing and penetrating dyeing of nylon, and the temperature is kept at 110 ℃ for 65-80min to be beneficial to dye on nylon and spandex.
Preferably, the step of raising the temperature in S32 specifically includes the following steps:
s321, first-step temperature rising: heating to 55-60 deg.C at a rate of 0.3-1.5 deg.C/min, and maintaining for 10-15 min;
s322, second-step temperature rising: heating to 75-85 deg.C at a speed of 0.3-1.5 deg.C/min, and maintaining for 15-25 min;
s323, third temperature rise: heating to 95-105 deg.C at a speed of 0.3-1.5 deg.C/min, adjusting pH to 4-5, and maintaining for 50-60 min.
By adopting the technical scheme, the dyeing speed of the two dyes is in direct proportion to the dyeing temperature, the dyes are dyed by heating to 55-60 ℃, the dyes can be promoted to diffuse into the fiber, and the dye penetration is facilitated by heating to 75-85 ℃, so that the color fastness is improved; the temperature is raised to 95-105 ℃, so that the dye combined with the dye is promoted to be transferred and dyed on the fiber, and the depth of the dye is improved; in addition, the dye has different dye-uptake degrees to different fibers under different pH value environments, the nylon is easier to dye when the pH value is higher, the spandex is easier to dye when the pH value is lower, and the dye-uptake degree on the spandex is enhanced by controlling the heat preservation time after the pH value is 4-5, so that the overall level-dyeing property of the fabric is improved.
Preferably, the heating rate of the first step of heating in the S321 is 1.2-1.5 ℃/min; the temperature rise rate of the second temperature rise in the S322 is 0.8-1.0 ℃/min; the temperature rise rate of the third temperature rise in the S323 is 0.3-0.7 ℃/min.
By adopting the technical scheme, the dyeing speeds of the two dyes are in direct proportion to the heating speed, the higher the heating speed is, the higher the dye-uptake rate of the dyes is, but the color fastness is not high at the moment; the slower the temperature rise, the lower the dye uptake, but the color fastness is improved, so by limiting the temperature rise rate at different temperatures, the competitive dyeing and the dyeing flower phenomena can be reduced.
Preferably, the color fixing step in S33 specifically is: cooling to 65-75 deg.C at a speed of 1.0-1.5 deg.C/min, adjusting pH to 4.0-4.5, adding 1.5-2% (omf) anionic color fixing agent, and keeping the temperature for 15-20 min; continuously adding 1-1.5% (omf) of anionic color fixing agent, and keeping the temperature for 20-30 min.
Through adopting above-mentioned technical scheme, through anionic fixing agent, can further improve the colour fastness of dyestuff on the fibre, and at 65-75 ℃, pH 4-5, add fixing agent in batches and can improve the fixation effect of this curing agent to the surface fabric to improve the colour fastness of surface fabric.
