Description

Technical Field

[0001] This invention relates to the field of textile technology, and in particular to a dyed garment and a dyeing method thereof. Background Technology

[0002] As living standards improve, people's demands for clothing are becoming increasingly personalized and diversified. A more pronounced bone structure look, as a relatively new clothing style, is gaining popularity.

[0003] In traditional dyeing and finishing processes, to achieve a clear contrast between the seam and the garment body, heavy washing and acid washing methods are often used. Heavy washing requires a large amount of abrasives and bleaching agents such as alkalis and oxidants. In the washing machine, friction and the bleaching agents work together to achieve a worn-out appearance with whitish seams. However, during heavy washing, the mechanical friction of the washing machine causes significant loss of fabric strength and can easily lead to quality problems such as abrasion at the seams. Furthermore, heavy washing requires the use of large amounts of white stones and clay as bleaching agents, generating a large amount of solid waste and increasing the pressure and cost of solid waste disposal. Acid washing often uses strong oxidants such as potassium permanganate and bleach, combined with carriers such as sand and stones, to achieve a specific effect by dry-frying the colored garment in a vat. However, the strong oxidizing and stripping agents used in acid washing methods, such as potassium permanganate and bleach, require a large amount of reducing agents for reduction and debleaching, which greatly damages the strength of the fabric. Moreover, the solid wastes from reducing agents commonly used in the industry, such as oxalic acid and sodium bisulfite, cause significant pollution to the natural environment and are not conducive to sustainable development. Summary of the Invention

[0004] Therefore, it is necessary to provide a garment dyeing method and dyed garments that can be industrially promoted, is easy to operate, is environmentally friendly, and can achieve the effect of highlighting bone structure.

[0005] In a first aspect, the present invention provides a garment dyeing method, comprising the following steps:

[0006] The garment is completely soaked in a dye-resisting solution, and then dried and cured to obtain a cured garment; the dye-resisting solution contains a thermophoretic migration dye-resisting resin, and the concentration of the thermophoretic migration dye-resisting resin in the dye-resisting solution is 5 g / L-200 g / L; and

[0007] The cured garment is then dyed.

[0008] This application uses thermophoretic migration dyeing-resistant resin as the dyeing-resistant agent component in the dyeing-resistant solution. The garment is then soaked in the dyeing-resistant solution and dried and cured. During the drying process, the resin migrates to areas of higher temperature on the garment and continues to cure at high temperature, achieving the dyeing-resistant effect. This results in a lighter color on the garment body due to the dyeing resistance. However, the garment at the seam seams is thick and difficult to dry, and the temperature is lower than that of the garment body. The thermophoretic migration dyeing-resistant resin at the seam seams migrates to the garment body. By controlling the concentration of thermophoretic migration dyeing-resistant resin in the dyeing-resistant solution, all the thermophoretic migration dyeing-resistant resin at the seam seams can migrate to the garment body, effectively dyeing the seam seams and making the seam seams more prominent, thus achieving a dyeing effect that highlights the seam seams.

[0009] The dyed garments obtained by the above method have obvious dyeing effects with prominent bone structure and little loss of strength. The process is simple and easy to operate, does not generate excessive solid waste, is green and environmentally friendly, and is conducive to industrial promotion.

[0010] In some embodiments, the thermophoretic staining barrier resin is selected from thermosetting resins.

[0011] In some embodiments, the thermophoretic staining barrier resin is selected from at least one of Albenol NR-12 and Linex-ab28.

[0012] In some embodiments, the concentration of the thermophoretic migration resisting resin in the resisting solution is 50 g / L-200 g / L.

[0013] In some embodiments, the liquid content of the wetted garment is 50%-160%.

[0014] In some embodiments, the liquid content of the wetted garment is 80%-130%.

[0015] In some embodiments, the step of wetting the garment includes: spraying the dye-resistant liquid onto the surface of the garment using a spray gun; or immersing the garment in the dye-resistant liquid.

[0016] In some embodiments, the drying and curing process includes drying the wetted garment at 100°C-105°C for 70-100 minutes to obtain a cured garment.

[0017] In some embodiments, the dyeing process is followed by a sequential washing and drying process.

[0021] To facilitate understanding of the present invention, a more comprehensive description is provided below, along with preferred embodiments. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. It should be understood that these embodiments are provided to provide a thorough and complete understanding of the disclosure of the present invention.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] The weights of the relevant components mentioned in the embodiments of this invention can refer not only to the specific content of each component, but also to the proportional relationship between the weights of the components. Therefore, any scaling up or down of the content of the relevant components according to the embodiments of this invention is within the scope disclosed in the embodiments of this invention. Specifically, the weights mentioned in the embodiments of this invention can be well-known units of mass in the chemical industry, such as μg, mg, g, and kg.

[0024] Thermophoretic migration inhibitory resins are resins that exhibit migration and dye-blocking properties depending on temperature differences. Uneven distribution of thermophoretic migration inhibitory resins on garments can create localized dye-blocking effects.

[0025] Liquid carry-over rate refers to the amount of liquid carried by the fabric after wetting. The calculation formula is: Liquid carry-over rate = (Weight of fabric after wetting - Weight of fabric before wetting) / Weight of fabric before wetting × 100%.

[0026] One embodiment of the present invention provides a garment dyeing method and a dyed garment obtained by the method. The garment dyeing method of one embodiment includes the following steps S10-S20:

[0027] S10. Wet the garment completely with the dyeing inhibition solution; the dyeing inhibition solution contains thermophoretic migration dyeing inhibition resin, and the concentration of the thermophoretic migration dyeing inhibition resin in the dyeing inhibition solution is 5g / L-200g / L.

[0028] S20. The wetted garment is dried and cured to obtain a cured garment.

[0029] S30. The cured garment is then dyed.

[0030] This application uses thermophoretic migration dyeing-resistant resin as the dyeing-resistant agent component in the dyeing-resistant solution. The garment is then soaked in the dyeing-resistant solution and dried and cured. During the drying process, the resin migrates to areas of higher temperature on the garment and continues to cure at high temperature, achieving the dyeing-resistant effect. This results in a lighter color on the garment body due to the dyeing resistance. However, the garment at the seam seams is thick and difficult to dry, and the temperature is lower than that of the garment body. The thermophoretic migration dyeing-resistant resin at the seam seams migrates to the garment body. By controlling the concentration of thermophoretic migration dyeing-resistant resin in the dyeing-resistant solution, all the thermophoretic migration dyeing-resistant resin at the seam seams can migrate to the garment body, effectively dyeing the seam seams and making the seam seams more prominent, thus achieving a dyeing effect that highlights the seam seams.

[0031] The dyed garments obtained by the above method have obvious dyeing effects with prominent bone structure and little loss of strength. The process is simple and easy to operate, does not generate excessive solid waste, is green and environmentally friendly, and is conducive to industrial promotion.

[0032] The aforementioned "5g / L-200g / L" can be 5g / L, 40g / L, 60g / L, 70g / L, 80g / L, 100g / L, 120g / L, 150g / L, 160g / L, 180g / L, or 200g / L. Further, the concentration of the thermophoretic migration inhibitory resin in the inhibitory solution can be any of the above-mentioned values ​​within a range. Preferably, the concentration of the thermophoretic migration inhibitory resin in the inhibitory solution is 50g / L-200g / L.

[0033] Furthermore, the concentration of the thermophoretic migration inhibitory resin in the inhibitory solution is 50 g / L-100 g / L.

[0034] In some embodiments, the thermophoretic staining barrier resin is selected from thermosetting resins.

[0035] In some embodiments, the thermophoretic migration inhibitor resin may be selected from at least one of anionic aromatic sulfonic acid condensation products and aromatic sulfonate polymers. Further, the thermophoretic migration inhibitor resin may be selected from at least one of sodium m-nitrobenzenesulfonate and ammonium phenylhydrazine sulfonate.

[0036] In some embodiments, the thermophoretic staining barrier resin is selected from at least one of Albenol NR-12 and Linex-ab28.

[0037] In some embodiments, the method for preparing the resist solution includes: completely dissolving the thermophoretic resist resin in room temperature soft water to obtain the resist solution.

[0038] In some embodiments, the method of wetting the garment can be achieved by spraying the dye-resistant liquid onto the surface of the garment using a spray gun.

[0039] In some embodiments, when using a spray gun to spray the dye-resistant liquid onto the surface of the garment, the spray gun can use 2-6 nozzles for spraying.

[0040] Furthermore, when using a spray gun to spray the dye-resisting solution onto the garment surface, the spray gun can use 3-4 nozzles for spraying. Controlling the number of nozzles on the spray gun helps to control the spraying speed of the dye-resisting solution and the spraying amount between garments in the same machine, avoiding poor results caused by localized spraying and improving the uniformity of spraying the entire garment.

[0041] In some embodiments, when the dye-resisting liquid is sprayed onto the garment surface using a spray gun, each nozzle can be equipped with 2-6 feed rings. Further, each nozzle can be equipped with 3-5 feed rings. By setting the feed rings on the nozzles, the droplet size of the dye-resisting solution during spraying can be controlled, thereby better controlling the uniformity of the dye-resisting liquid wetting the garment, further improving the dye-resisting effect on the garment body, and thus enhancing the seam protrusion effect.

[0042] In some embodiments, the method of wetting the garment may be by immersing the garment in a dye-resisting solution.

[0043] In some embodiments, the soaking time can be 10 min to 30 min.

[0044] In some embodiments, the liquid retention rate of the wetted garment can be 50%-160%. By controlling the liquid retention rate of the wetted garment, the uniformity of the dye-resistant solution's wetting of the garment and the dye-resistant area can be controlled in a positive correlation.

[0045] The aforementioned "50%-160%" can be 50%, 80%, 100%, 120%, or 160%. Further, the liquid retention rate of the wetted garment can be any of the above-mentioned values ​​within a range. Preferably, the liquid retention rate of the wetted garment is 80%-130%. Further, the liquid retention rate of the wetted garment is 100%-110%. In some embodiments, during the process of completely wetting the garment with the dye-resistant solution, the ratio of the volume of the dye-resistant solution to the mass of the garment can be (0.5-1.6) L:1 kg. By controlling the ratio of the volume of the dye-resistant solution to the mass of the garment, not only can the amount of chemicals used in the preparation of the dye-resistant solution be better controlled, but the liquid retention rate of the wetted garment can also be controlled more accurately.

[0046] The aforementioned "(0.5-1.6) L:1Kg" can be 0.5L:1Kg, 0.8L:1Kg, 1L:1Kg, 1.2L:1Kg, or 1.4L:1Kg. Further, the ratio of the volume of the dye-resistant solution to the weight of the garment can be any of the aforementioned values ​​within a range. Preferably, the ratio of the volume of the dye-resistant solution to the weight of the garment is (1-1.1) L:1Kg.

[0047] In some embodiments, the step of drying and curing the wetted garment includes: drying the wetted garment at 100°C-105°C for 70-100 minutes to obtain a cured garment.

[0048] In some embodiments, the step of drying and curing the wetted garment includes: drying the wetted garment at 100°C-105°C for 30-60 minutes to ensure that the garment is dried, and then continuing to dry for another 40-60 minutes to cure the thermophoretic transfer resin to obtain a cured garment.

[0049] In some embodiments, the dyeing process includes placing the garment and dye solution in a dyeing machine for dyeing.

[0050] In some embodiments, the ratio of the volume of the dye solution to the weight of the garment is (0.5-1.6) L:1 Kg.

[0051] In some embodiments, the dye solution contains dye, sodium sulfate, and a fixing agent.

[0052] In some embodiments, the concentration of sodium sulfate in the dye solution is 30 g / L-90 g / L. Controlling the amount of sodium sulfate can further promote dyeing.

[0053] In some embodiments, the fixing agent in the dye solution is 10 g / L-20 g / L.

[0054] In some embodiments, the fixing agent may be selected from at least one of soda ash, polyurethane copolymer or cationic quaternary ammonium salt.

[0055] In some embodiments, the dyeing treatment temperature is 60°C-70°C.

[0056] In some embodiments, the staining treatment time is 85 min-115 min.

[0057] In some embodiments, the dyeing process is followed by a sequential washing and drying process.

[0058] In some embodiments, the liquor ratio for the washing process is 1:20-30. Controlling the liquor ratio for the washing process helps to ensure sufficient water volume, allowing the garment to be more thoroughly soaked, thus better controlling the washing effect, while also minimizing waste of washing solution.

[0059] In some embodiments, the washing temperature can be 30°C-50°C. Optionally, the washing temperature can be 30°C, 35°C, 40°C, 45°C, or 50°C. Controlling the washing temperature helps to achieve the required temperature parameters for the washing process, thereby better controlling the washing effect.

[0060] In some embodiments, the washing time is 15-60 minutes. Optionally, the washing time is 15 minutes, 20 minutes, 25 minutes, 30 minutes, 40 minutes, 50 minutes, or 60 minutes. Further, the washing time can be a range formed by any two of the above values. Further, the washing time is 20-40 minutes. By controlling the washing time, the intensity of the washing and the softness of the hand feel can be adjusted.

[0061] In some embodiments, the aqueous solution used for the washing process includes a softener. The concentration of the softener is 1 g / L to 3 g / L.

[0062] In some embodiments, the pH value of the aqueous solution used in the washing process is 5-5.5. Controlling the pH value of the aqueous solution in the washing process can achieve the required acidity or alkalinity for washing, thereby better controlling the washing effect.

[0063] In some embodiments, the drying temperature can be 60°C-80°C.

[0064] In some embodiments, the drying time can be 20-30 minutes.

[0180] Comparative Example 3

[0181] (1) Preparation of bleach: Weigh 0.09 kg of sodium hypochlorite solution (concentration of 11%), pour it into a dissolving tank, and dissolve the bleach with room temperature soft water. The amount of soft water used is 4.91 L, and a bleach mixture is obtained.

[0182] (2) Preparation of the spraying machine: Turn on the three nozzles 1 / 3 / 5 of the spraying machine (product model: GreenMachine spraying machine of Guangdong Yida Textile Co., Ltd.). Each nozzle is equipped with two discharge rings. Then, use room temperature water to clean the inside of the machine and the spraying hose.

[0187] The raw materials and concentrations of the dyeing inhibitor solutions used in each embodiment and comparative example, the amount of fabric used, and the dyeing effect are shown in Table 1.

[0188] Table 1:

[0189]

[0190] Performance testing

[0191] Color fastness test: Water fastness: tested according to GB / T 5713-2013; Rubbing fastness: tested according to GB / T3920-2008; Light fastness: tested according to GB / T 8427-2008.

[0192] Strength test: The test shall be conducted in accordance with GB / T 19976-2005.

[0193] The color fastness, fabric strength, spray strength, dyeing strength, and washing strength of the dyed garments of Examples 1-18 and Comparative Examples 1-3 were tested, and the test results are shown in Table 2.

[0194] Table 2:

[0195]

[0196] Wherein, original fabric strength refers to the strength of the garment to be treated; post-spray strength refers to the strength of the garment after drying and curing; post-dyeing strength refers to the strength of the garment after dyeing and drying; and post-washing strength refers to the strength after washing and drying. Change in post-washing strength = (Original fabric strength - Post-washing strength) / Original fabric strength * %.

[0197] As can be seen from the data in Tables 1 and 2, the concentration of the dyeing inhibitor used in Comparative Example 1 reached 250 g / L, and its dyeing inhibition effect on the dyed garments was obvious. However, due to the excessively high concentration of thermophoretic migration dyeing inhibitor resin in the dyeing inhibitor, the thermophoretic migration resin remained at the seam during the drying process of the wetted garments, causing the garments to turn white overall and lacking the effect of prominent seam. Comparative Example 2 used a heavy water washing method to obtain a dyeing effect with prominent seam and overall whitening and aging, but its strength after washing was only 383, which was 32.21% lower than the original strength of the fabric. Comparative Example 3 used an acid washing method to obtain a fabric with obvious gradient color difference and fading and whitening effect, which was not as good as the overall dyeing inhibition effect of Examples 1-18, and its strength after washing was only 384, which was 32.03% lower than the original strength of the fabric. In contrast, the dyed garments prepared by the technical solution of this application in Examples 1-18 had a dyeing effect with prominent seam, and the strength of the fabric after washing could be maintained above 385 N, with relatively little damage to the strength of the fabric. Its color fastness to washing, color fastness to rubbing, and color fastness to drying all meet the standards.

[0198] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
