Description
Technical Field
The invention belongs to the technical field of jean dyeing and finishing and clothing manufacturing, and particularly relates to a method for manufacturing colored jean yarns, and fabric and clothing manufactured by using the yarns.
Background
Beautiful jeans wear is deeply loved by the consumers and has large market sales. The relevant data shows that the global market volume for cowboy wear has increased 8.9% from 2013 to 2018, from $ 526 billion to $ 573 billion, and is expected to reach $ 600 billion annual market volume by 2023.
The conventional jeans wear mainly uses indigo and sulfur black dyed fabric, most of the current jeans wear adopts raw cotton yarn to be sent to a clothing factory after being sent to a sizing and dyeing combination machine or a ball warp dyeing machine, weaving is removed, the grey cloth is sent to the clothing factory after desizing, singeing and preshrinking treatment, and the clothing is washed by various methods after clothing manufacturing, so that the effects of washing and fading are achieved. The raw cotton yarn is dyed on a sizing and dyeing combination machine or a ball warp dyeing machine to prepare indigo blue and sulfur black, and the clothes dyed by the indigo blue and the sulfur black have serious fading, extremely poor wet rubbing fastness, only the lowest level of 1 grade and poor multi-fiber staining fastness due to equipment and process, so that the clothes cannot be worn together with light-colored clothes, cannot be matched with white clothes, and is more seriously stained during washing.
In the market of jeans, the layered feeling of jeans is imitated by using pigment dyeing, and due to the pigment adhesive and the cross-linking agent, the pigment has single decolorization degree and cannot achieve the washing effect of the jeans with clear layers; the laser etching is also used for imitating the layering sense of jeans, but the laser etching treatment cost is too high, a large amount of harmful gas can be generated in the treatment process, and a large amount of high-chroma sewage can be generated for removing the woven slurry after the laser etching.
Disclosure of Invention
In order to solve the above problems, an object of the present invention is to provide a method for manufacturing a colored denim yarn, such that the denim yarn manufactured by the method has good color fastness and is not easy to fade.
In order to achieve the purpose, the invention provides a method for manufacturing colored jean yarns, which comprises the following steps:
dyeing pretreatment of cotton loose fibers: loading undyed cotton loose fibers into a dyeing tank, treating for 40-45min at 90 ℃ by adopting a pretreatment auxiliary agent, and then washing with water. Wherein the water washing comprises the specific steps of firstly washing with water at 85-90 ℃ for 20 minutes, and then washing with water at 80-85 ℃ for 15-20 minutes. The pretreatment auxiliary agent is any combination of one or more of refining agent, scouring agent and penetrating agent for cotton and caustic soda. The cotton refining agent is preferably a cotton refining enzyme. The scouring agent is preferably scouring enzyme.
The dyeing pretreatment of the cotton loose fibers aims to remove impurities such as grease, wax and the like on the cotton loose fibers and enhance the permeability of the cotton loose fibers so as to improve the dye uptake of dyes during dyeing.
Dyeing loose cotton fibers, namely, when the loose cotton fibers are placed in a vat, controlling the amount of the loose cotton fibers subjected to dyeing pretreatment and the working solution for dyeing the leuco dye according to a certain bath ratio, heating at the heating rate of 0.5-1 ℃/min, preserving heat for 10-70min when the temperature reaches 50-85 ℃, finishing dyeing, adding 15-35 g/L of an accelerating agent during heat preservation, preserving heat at one temperature value, or preserving heat at a plurality of temperature values in stages, and adding the accelerating agent once or for a plurality of times.
The vat dye is also called vat dye, because the vat dye has large particles, the vat dye is pre-reduced to form leuco sodium salt, the particle size of the dye in the dye solution is reduced, meanwhile, the leuco sodium salt is in a negative charge state, the leuco sodium salt is favorably combined with cotton loose fibers with positive charges, and the dye is oxidized to form water-insoluble dye lake, so that the dyeing fastness is improved, and the color is not easy to fade. Vat dye leuco dyeing working solution is prepared from Vat dye, the advantages that the molecular kinetic energy of the dye is increased under the high-temperature condition and the dye is easy to diffuse into cotton loose fibers are utilized, and the dyeing rate and the core penetrating effect of cotton loose fiber dyeing are adjusted by adjusting the temperature during dyeing. The dyeing conditions of the cotton loose fibers are preferably as follows: adding a vat dye leuco dyeing working solution into the cotton loose fibers subjected to dyeing pretreatment, heating at a heating rate of 0.5-1 ℃/min, keeping the temperature for 30-70min when the temperature reaches 60-85 ℃, and adding an accelerating agent when keeping the temperature. Under the optimal condition, the dye uptake and the core penetration effect of the cotton loose fibers are most suitable for realizing the effects of colorful and multi-level jeans garments in the subsequent manufacture of colorful jeans garments.
Wherein, on the basis of ensuring the process reliability, the temperature rise rate is determined to be 0.5-1 ℃/min by considering the operation convenience and the cost. If the temperature rise rate is higher than 1 ℃/min, the temperature rise is too fast, so that the dyeing is too fast, and uneven color is generated; and the heating rate is lower than 0.5 ℃/min, the heating time is too long, the time consumption is long, and the dyeing cost is high.
The bath ratio does not affect the effect of the color fastness, but is lower than 1:10, uneven dyeing is easy to occur, and the bath ratio is too large and the cost is too high, so that the bath ratio of 1:10-20 is preferred.
The accelerating agent is used for breaking the resistance of dye adsorption and diffusion by utilizing the concentration difference of electrolyte, accelerating the dye molecules to diffuse into the cotton loose fibers, and further improving the dye uptake of the vat dye leuco dye solution to the cotton loose fibers. The accelerating agent is added in several times, so that the dye-uptake rate can be slowed down, and the phenomenon of uneven dyeing caused by too fast dye-uptake can be reduced. The accelerant used in the invention is anhydrous sodium sulphate, sodium chloride or a mixture of anhydrous sodium sulphate and sodium chloride.
Dyeing and post-treating cotton loose fibers: after the dye liquor in the dyeing vat is drained, washing the cotton loose fibers for 2-3 times by using normal-temperature water, namely, washing and oxidizing by using oxygen in the normal-temperature water; then adopting water added with an oxidant to wash, namely performing forced oxidation, wherein the forced oxidation process needs to be fully oxidized; then, a single soaping agent or a mixed solution of the soaping agent and a dispersing agent is adopted for high-temperature soaping, so that dye molecules are rearranged, and the soaping fastness is improved; then washing with water of 80-85 deg.C and normal temperature water, removing residual floating color, dewatering, and oven drying.
Wherein the dosage of the soaping assistant is generally 1-3 g/L.
Blending the blended yarns: and (4) carrying out mixed spinning on the cotton loose fibers subjected to the post-dyeing treatment and the undyed cotton loose fibers.
Wherein the percentage of the cotton loose fibers after dyeing is 10-95%. Since the dyeing is very pale visually when the cotton loose fiber content after dyeing is less than 10%, and the color depth is close to the fully dyed color visually when it is more than 95%, the cotton loose fiber content after dyeing is preferably 10% to 95%.
In the dyeing of cotton loose fibers, the vat dye leuco dye working solution is prepared by diluting a pre-prepared high-concentration vat dye leuco dye mother solution.
The preparation method of the high-concentration vat dye leuco dye mother liquor comprises the following steps:
adding 50-60% of normal temperature water into a container, heating to 40-45 ℃, adding 50-80 g/L of alkaline agent while stirring, heating while stirring, pouring 300 g/L of Shilin dye when the temperature reaches 80-85 ℃, fully stirring for 20-30 min, adding 40-80 g/L of reducing agent when the temperature is reduced to 40-45 ℃, stirring for 3-5 min, standing for 40-45min, and adding normal temperature water until the total liquid amount reaches 100% to obtain the high-concentration vat dye leuco dye solution.
Wherein the Vaseline dye is one or a mixture of several Vaseline dyes such as Vaseline blue VB dye, Vaseline yellow G dye, Vaseline olive T dye, Vaseline green FFB dye, Vaseline red F3B dye or Vaseline black RB dye. The alkaline agent is one or more of caustic soda, soda ash or alkaline substances of strong base and weak acid salts. The reducing agent is a composite reducing agent RSW or a composite reducing agent RSD.
The preparation process of the leuco dyeing working solution of the vat dye comprises the following steps: preparing high-concentration vat dye leuco dye mother liquor in advance according to the method, and storing for later use; before dyeing, diluting the high-concentration vat dye leuco dye mother liquor by 20-50 times with normal-temperature water, and measuring and adjusting a reduction potential value and/or a pH value to obtain the vat dye leuco dyeing working solution. When different Vaseline dyes are adopted to dye cotton loose fibers, the requirements on the reduction potential value and the pH value range of the working solution for dyeing the leuco dye of the vat dye are different, so after the mother solution of the leuco dye of the high-concentration vat dye is diluted by normal-temperature water, a reducing agent is adopted to adjust the reduction potential value, and the reduction potential value is controlled within the range required by dyeing of the Vaseline dyes; caustic soda is used to adjust the pH to within the desired range for dyeing the threne dye.
The invention also aims to provide the denim fabric manufactured by using the denim yarn, and the denim fabric has good dyeing fastness and is not easy to fade after washing.
The invention also aims to provide a garment made of the jean fabric. Because the grains of the vaseline dye are large and the dyed core is not easy to penetrate, the jeans garment made of the jeans fabric can obtain rich and colorful jeans garment effects with multiple layers by controlling different washing methods.
The invention has the following advantages:
(1) in the manufacturing method of the colorful jean yarn, the vat dye leuco dye liquor is adopted to dye the cotton loose fibers, so that the manufactured jean yarn has good dyeing fastness, is not easy to fade, and particularly has excellent light fastness and excellent soaping fastness;
(2) in the patent, the defects of large particles and difficult core penetration of dyeing of the vaseline dye are utilized to convert the defects into advantages, and the local decolorization is realized under different washing methods such as common washing water, enzyme washing water, manual hand wiping or oxidant washing of the garment ready-made clothes, so that the layered jeans garment effect is formed on the garment.
(3) Compared with the traditional denim dyeing process, the method has the advantages that in the process of producing the clothes, sewage and polluted gas are less, and the sewage generated in the dyeing and water washing processes is easy to collect and is convenient for environment-friendly treatment.
