Description

Technical Field

[0001] The present invention relates to the technical field of garment finishing, and specifically to a finishing process for a moisture-absorbing and quick-drying ready-to-wear non-iron shirt. Background Art

[0002] Pure cotton shirts are deeply loved by consumers for their comfortable wearing, excellent air permeability, strong moisture absorption, soft hand feeling, environmental friendliness, etc.

[0003] After people do strenuous exercise, a large amount of sweat will be produced. Whether it is the liquid sweat staying on the skin surface or the gaseous sweat between the skin and the clothing, it will make people feel uncomfortable. At this time, the timely and rapid absorption and discharge of liquid sweat or gaseous sweat by the fabric (moisture-absorbing and quick-drying property) is very important.

[0004] However, there are still some drawbacks in the wearing process of traditional pure cotton shirts, mainly including the following three points: 1. It is easy to wrinkle during wearing and washing, and its non-creased and unbeautiful characteristics after washing bring a lot of inconvenience to consumers. 2. The warmth retention of pure cotton shirts is relatively good, which will give people a feeling of stuffiness when the temperature is high. 3. Shirts are not convenient to carry and are easy to wrinkle, which troubles business travelers. Therefore, the production of ready-to-wear non-iron shirts that are convenient to wash, wear, and maintain is very much in line with modern people's various requirements for clothing, such as environmental protection, health, comfortable wearing, and convenient carrying.

[0005] The present invention makes technological innovations in production. While making the ready-to-wear non-iron, it endows the shirt with moisture-absorbing and quick-drying performance, produces high-value-added products with multiple functions with the labor cost of one functional finishing, and the product has a relatively high cost performance, which also very much meets the market demand. Summary of the Invention

[0006] Aiming at the deficiencies of the prior art, the present invention provides a finishing process for a moisture-absorbing and quick-drying ready-to-wear non-iron shirt, which solves the problems that traditional pure cotton shirts are easy to wrinkle after washing and have poor moisture-absorbing and quick-drying performance.

[0007] To achieve the above objectives, the present invention is realized through the following technical solutions: A finishing process for a moisture-absorbing and quick-drying ready-to-wear non-iron shirt, including the following steps: S1. Garment making Select polyester thread with a low shrinkage rate, use a two-needle five-thread overlock process for the side seams to make the garment, and add anti-wrinkle linings at the armholes, side seams, shoulder seams, back yokes, and large sleeve slits of the shirt. Finally, press and iron at a temperature of 165°C and a pressure of 3.0 kg / cm 2 for 15 s; S2. Functional finishing First, apply the chemical finishing agent evenly through atomized spraying, and then pre-dry to adjust the liquor pickup rate to 35% - 50%; then pre-iron to control the humidity of the stitches and the body, and then press in a specific order to make the auxiliaries penetrate into the fibers and be preliminarily shaped; then cure to promote the full reaction of the resin and the fibers, and finally quickly cool and moisturize in a freezing room at 0 - 5°C to achieve the performance of wrinkle-free, moisture absorption and sweat discharge, etc. and lasting flatness of the shirt; S3. Shirt washing Put the shirt into an industrial washing machine for washing. The washing temperature is 25 - 35°C, add a pH buffer solution to adjust the pH to 5 - 6, and add a softener. Wash for 12 minutes to further remove the residual substances on the shirt and improve the hand feeling.

[0008] Preferably, the specific steps of step S2 are as follows: S21. Spraying medicine After preparing the auxiliary raw materials into a stable chemical finishing agent according to the proportion, atomize and spray the shirt according to the weight of the clothing, and control the liquor pickup rate at 85% - 95%; S22. Pre-drying Pre-dry the sprayed shirt, control the liquor pickup rate between 35% - 50%, and the drying temperature is below 45°C; S23. Pre-ironing Slightly spray the shirt wet with a watering can filled with clear water and let it stand for 2 - 3 minutes, then iron with an iron, control the liquor pickup rate of the stitch part at 15% - 20%, and the liquor pickup rate of the body part at 10% - 15%; S24. Pressing For the pre-ironed shirt, press it in the order of collar, cuff, side seam, sleeve, yoke, front piece, and back piece. On the one hand, make the finished shirt more flat, and on the other hand, make the wrinkle-free resin and the moisture absorption and sweat discharge finishing agent penetrate into the fibers as much as possible and combine with the fibers. The pressing temperature is 115°C - 135°C, and the pressure is 3 - 5 kg / cm 2 , press for 8 - 15 s to preliminarily shape the shirt; S25. Curing Cure the pressed shirt. The curing temperature is 100°C - 130°C, and the time is 3 - 6 minutes, so that the finishing agent and the fibers completely react; S26. Cooling and moisturizing Put the cured shirt into the freezing room and cool and moisturize it in a space of 0 - 5°C. The cooling treatment time is 10 - 15 s.

[0009] Preferably, the raw materials of the chemical finishing agent include wrinkle-free resin, hydrophilic softener, catalyst, hydrophilic quick-drying agent, protective agent and penetrant.

[0010] Preferably, the weight ratio of each raw material of the chemical finishing agent is 150:30:30:130:30:0.5.

[0011] Preferably, the anti-wrinkle resin is butanetetracarboxylic acid or aqueous polyurethane dispersion, and the hydrophilic softener includes but is not limited to any one or a combination of polydimethylsiloxane, amino-modified silicone oil, polyether-modified silicone oil, etc., and the catalyst is triethanolamine or ammonium dihydrogen phosphate.

[0012] Preferably, the hydrophilic quick-drying agent includes but is not limited to any one or a combination of sodium polyacrylate, poly (2-hydroxyethyl methacrylate), polyethylene terephthalate-polyethylene glycol copolymer, etc., and the protective agent includes but is not limited to any one or a combination of glycerol, acrylate polymer, chitosan, polyethylene wax emulsion, etc. The penetrant includes but is not limited to any one or a combination of fatty alcohol polyoxyethylene ether, alkyl sulfonate, sodium dioctyl sulfosuccinate, etc.

[0013] The present invention provides a finishing process for moisture-absorbing and quick-drying ready-to-wear non-iron shirts. It has the following beneficial effects: In the present invention, anti-wrinkle linings are added to the shirt armholes, side seams, shoulder seams, back yokes, and large sleeve slits during sewing, and ironed at a temperature of 165 °C and a pressure of 3.0 kg for 15 s to improve the flatness of the seams after the ready-to-wear is washed.

[0014] After making the ready-to-wear, the present invention selects a moisture-absorbing and sweat-wicking finishing agent with reaction conditions close to those of the anti-wrinkle resin, and uses a ready-to-wear non-ironing device to perform non-ironing finishing and moisture-absorbing and quick-drying finishing on the ready-to-wear at the same time, avoiding damage to the fabric caused by multiple finishing and affecting the wearing performance.

[0015] In the present invention, the ready-to-wear after high-temperature baking is immediately placed in a space of 0-5 °C and frozen for 15 s to improve the flatness of the fabric. Under the physical action of alternating hot and cold, it gives the shirt a plump handfeel, reduces the stiffness caused by making ready-to-wear non-ironing, and at the same time volatilizes the residual chemical substances on the clothes. After freezing, it is washed with water at 25-35 °C for 12 min, a pH buffer solution is added to adjust the pH to 5-6, and a softener is added at the same time to further remove the residual substances on the shirt and improve the handfeel, giving the pure cotton shirt a soft and comfortable handfeel and green and environmentally friendly wearing performance.

[0016] Due to its small particle size, the carrier of the moisture-absorbing and sweat-evaporating chemical finishing agent of the present invention is easy to penetrate into the fiber. After entering the fiber, the carrier crosslinks with the fiber, enabling the fabric to obtain quick-drying property. The non-iron resin utilizes its functional groups to also covalently crosslink with the active groups of the cellulose macromolecules, forming a network structure that restricts the relative sliding between the macromolecules, improves the dimensional stability of the fiber, and enables the shirt to achieve the effect of being wearable after washing. Moreover, since the reaction conditions of the selected non-iron resin and the moisture-absorbing and sweat-evaporating finishing agent are close and the performance is stable, they are mixed with a catalyst and a softener to be compounded into a finishing agent for simultaneous non-iron finishing and quick-drying finishing. The fiber protectant in the raw materials has certain water-repellent properties and can be selected for high-quality compatibility, considering both the fiber protection effect and the ability to exert the rapid moisture absorption and drying performance without being affected. Detailed implementation mode

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention. Embodiment 1

[0018] The embodiment of the present invention provides a finishing process for a moisture-absorbing, quick-drying, and non-iron shirt, including the following steps: S1. Garment making Select polyester thread with a low shrinkage rate, and use a two-needle and five-thread overlock process for hemming the side seams to make the garment. Add anti-wrinkle linings at the armholes, side seams, shoulder seams, back yokes, and large sleeve slits of the shirt. Finally, press for 15 s at a temperature of 165 °C and a pressure of 3.0 kg / cm 2 ; S2. Functional finishing S21. Spraying the agent After preparing the auxiliary raw materials into a stable chemical finishing agent according to the ratio, atomize and spray the agent on the shirt according to the weight of the clothing, and control the liquor pickup rate at 85%. Since the finishing agent is atomized into small particles by the spraying machine, it is easy to penetrate into the cotton fiber, making the reaction more complete; S22. Pre-drying Controlling the liquor pickup rate at 85% during spraying is to make the clothing completely wet and prevent quality problems caused by incomplete wetting of multi-layer fabric parts such as yokes, collars, and cuffs. However, if the liquor pickup rate is too high, it is not conducive to the processing operations in the subsequent processes. Therefore, pre-dry the sprayed shirt to control the liquor pickup rate between 35%, and the drying temperature is below 45 °C; S23. Pre-pressing Gently spray the shirt with a spray bottle filled with clean water and let it stand for 2 minutes. Then use an iron to iron it, controlling the liquid content rate at 15% for the seam part and 10% for the main body part. The front and back pieces of the finished shirt have a relatively large area. After the pre-drying, the clothes are quite wrinkled and cannot be completely flattened by pressing alone. Pre-ironing can pre-flatten the larger pieces of the finished garment, fix the position of the non-ironing and moisture-absorbing and sweat-wicking finishing agents in the finishing agent, and make the distribution of the finishing agent in the larger pieces of the garment more uniform; S24. Pressing For the pre-ironed shirt, press it in the order of collar, cuff, side seam, sleeve, yoke, front piece, and back piece. On the one hand, make the finished shirt more flat. On the other hand, make the non-ironing resin and moisture-absorbing and sweat-wicking finishing agent penetrate into the fiber interior as much as possible and combine with the fiber. The pressing temperature is 115°C and the pressure is 3 kg / cm 2 , press for 8 s to preliminarily shape the shirt; S25. Baking Bake the pressed shirt. The baking temperature is 100°C and the time is 3 min to make the finishing agent react completely with the fiber; S26. Cooling and Moisture Absorption Put the baked shirt into the freezing room and cool and absorb moisture in a space of 0°C. The cooling treatment duration is 10 s. Under the physical action of alternating heat and cold, increase the moisture regain rate of the shirt, enhance the quick-drying property of the finished garment, and at the same time endow the shirt with a more plump handfeel; S3. Shirt Washing Put the shirt into an industrial washing machine for washing. The washing temperature is 25°C. Add a pH buffer solution to adjust the pH to 5 and add a softener. Wash for 12 min to further remove the residual substances on the shirt and improve the handfeel.

[0019] The raw materials of the chemical finishing agent include non-ironing resin, hydrophilic softener, catalyst, hydrophilic quick-drying agent, protective agent, and penetrant. The weight ratio of each raw material is 150:30:30:130:30:0.5.

[0020] The non-ironing resin is butanetetracarboxylic acid or aqueous polyurethane dispersion. The hydrophilic softener includes, but is not limited to, any one or a combination of polydimethylsiloxane, amino-modified silicone oil, and polyether-modified silicone oil. The catalyst is triethanolamine or ammonium dihydrogen phosphate.

[0021] The hydrophilic quick-drying agent includes, but is not limited to, any one or a combination of sodium polyacrylate, poly(2-hydroxyethyl methacrylate), and polyethylene terephthalate-polyethylene glycol copolymer. The protective agent includes, but is not limited to, any one or a combination of glycerol, acrylate polymer, chitosan, and polyethylene wax emulsion. The penetrant includes, but is not limited to, any one or a combination of fatty alcohol polyoxyethylene ether, alkyl sulfonate, and sodium dioctyl sulfosuccinate. Example 2

[0022] The embodiment of the present invention provides a finishing process for a moisture-absorbing, quick-drying and ready-to-wear non-iron shirt, which includes the following steps: S1. Garment making Select polyester thread with a low shrinkage rate, use the two-needle and five-thread overlock process for side seams during garment making, and add anti-wrinkle linings at the armholes, side seams, shoulder seams, back yokes, and large sleeve slits of the shirt. Finally, press and iron at a temperature of 165°C and a pressure of 3.0 kg / cm 2 for 15 s; S2. Functional finishing S21. Spraying medicine After preparing the auxiliary raw materials into a stable chemical finishing agent in proportion, atomize and spray the shirt according to the weight of the clothing, and control the liquor pickup rate at 95%. Since the finishing agent is atomized into small particles by the spraying machine, it is easy to penetrate into the cotton fibers, making the reaction more complete; S22. Pre-drying Controlling the liquor pickup rate at 95% during spraying is to make the clothing completely wet and prevent quality problems caused by incomplete wetting of multi-layer fabric parts such as yokes, collars, and cuffs. However, if the liquor pickup rate is too high, it is not conducive to the processing operations in the subsequent processes. Therefore, pre-dry the sprayed shirt to control the liquor pickup rate between 50%, and the drying temperature is below 45°C; S23. Pre-ironing Slightly spray the shirt with a watering can filled with clean water and let it stand for 3 minutes, then iron it with an iron. Control the liquor pickup rate of the seam part at 20% and the liquor pickup rate of the main body part at 15%. The front and back panels of the shirt are larger in area. After pre-drying, the clothes are relatively wrinkled and cannot be completely flattened by pressing and ironing alone. Pre-ironing can pre-flatten the larger panels in the finished garment, fix the positions of the non-iron and moisture-absorbing and sweat-wicking finishing agents in the finishing agent, and make the distribution of the finishing agent in the larger panels more uniform; S24. Pressing and ironing For the pre-ironed shirt, press and iron it in the order of collar, cuff, side seam, sleeve, yoke, front panel, and back panel. On the one hand, make the finished shirt more flat, and on the other hand, make the non-iron resin and moisture-absorbing and sweat-wicking finishing agents penetrate into the fiber interior as much as possible and combine with the fibers. The temperature for pressing and ironing is 135°C, the pressure is 5 kg / cm 2 , press and iron for 8 - 15 s to make the shirt preliminarily shaped; S25. Baking Bake the pressed and ironed shirt. The baking temperature is 130°C and the time is 6 min to make the finishing agent react completely with the fibers; S26. Cooling and moisture regain Put the baked shirt into a freezer and cool it to regain moisture in a space at 5°C for 15 seconds. Under the physical action of alternating hot and cold, the moisture regain rate of the shirt is increased, the quick-drying property of the finished garment is enhanced, and at the same time, the shirt is given a more plump handfeel. S3. Shirt washing Put the shirt into an industrial washing machine for washing. The washing temperature is 35°C, add a pH buffer to adjust the pH to 6, and add a softener. Wash for 12 minutes to further remove the residual substances on the shirt and improve the handfeel.
