Description

Technical Field

[0001] The invention relates to a process for producing wool knitted clothing. Background Art

[0002] Wool fiber is widely used in the production of high-end textiles due to its excellent warmth retention, excellent elasticity and good moisture absorption capacity. These characteristics of this natural fiber make it a favorite in the textile industry, especially in the production of winter clothing and high-end home furnishings.

[0003] In the traditional wool shaping process, various chemical reagents are often needed to fix the shape and structure of wool fibers. Although these chemical reagents can achieve the desired shaping effect to a certain extent, their use is often accompanied by damage to the wool fibers themselves. Chemical reagents may weaken the mechanical properties of wool fibers, resulting in a decrease in their strength and elasticity, thereby affecting the durability and service life of the final product. In addition, the use of chemical reagents may also bring about environmental pollution and health risks. During the processing of wool, residual chemicals may cause irritation or allergic reactions to human skin. At the same time, these chemicals are discharged into the environment during the production process, which will also have a negative impact on the ecosystem. For this reason, we propose a wool knitted garment production process. Summary of the invention

[0033] Embodiment 1:

[0034] Please refer to Figure 1 The present invention provides a wool knitted garment manufacturing process, comprising the following steps:

[0035] S1, knitting and weaving, using 60% ultra-fine wool fiber, 25% natural environmentally friendly fiber and 15% polyester fiber blended to make grey fabric;

[0036] S2, bio-enzyme treatment, using environmentally friendly bio-enzymes to treat the grey fabric;

[0037] S3, ultrasonic assisted dyeing treatment, washing and dyeing the grey cloth;

[0038] S4, low temperature drying and shaping, drying and shaping the dyed grey cloth;

[0039] S5, pre-shrinking treatment, pre-shrinking the dried grey cloth;

[0040] S6, post-finishing, post-finishing the pre-shrunk grey cloth;

[0041] S7, garment making, using pre-shrunk grey fabric for garment making.

[0042] In the knitting weaving of S1, three-dimensional weaving machines are used to blend and manufacture grey fabrics. This step introduces natural environmentally friendly fibers, which include one or more of bamboo fibers and regenerated cellulose fibers. These fibers not only have excellent moisture absorption, breathability and comfort, but also can improve the environmental properties of the fabric. Microcapsule technology is added to wrap tiny particles with functions such as warmth retention, antibacterial and deodorization in the fibers, and the effective ingredients are released through friction, giving the fabric more functionality.

[0043] Use of 3D knitting machine The 3DWeavingMachine 8000 produced by Textile Machinery can realize complex three-dimensional structure weaving and is suitable for the production of a variety of blended fabrics.

[0044] By introducing three-dimensional weaving technology during the knitting and weaving of S1, more air layers are formed in the structure of the grey fabric, further improving the thermal insulation performance while keeping the grey fabric light and soft. The longitudinal density of the three-dimensional weaving machine is 105 needles / inch and the transverse density is 84 needles / inch during knitting. On the original basis, the longitudinal and transverse densities are increased by 5% respectively to enhance the compactness and warmth of the grey fabric. The knitting tension of the three-dimensional weaving machine is 50-60cN. The tension is fine-tuned appropriately to ensure that the coil structure is uniform and consistent, thereby reducing the risk of unraveling.

[0045] In the biological enzyme treatment of S2, a continuous enzyme treatment machine is used, and environmentally friendly biological enzymes are selected to treat the grey cloth.

[0046] The continuous enzyme treatment machine used was the LH-1000 continuous enzyme treatment machine produced by Shanghai Linghang Biotechnology Co., Ltd.

[0047] During the bio-enzyme treatment, 30 to 120 m of grey cloth is put into the continuous enzyme treatment machine, and the weight bath ratio of the grey cloth to water is controlled to be 1:5 to 15, and then 30 g / L of environmentally friendly bio-enzyme preparation is added to the water, the speed of the grey cloth is controlled to be 100 to 350 m / min, the bio-enzyme treatment temperature is 50°C, and the bio-enzyme treatment time is 20 min. The treatment time is adjusted according to the activity of the environmentally friendly bio-enzyme preparation and the thickness of the grey cloth. The time is long for thick grey cloth and short for thin grey cloth. After completion, drain, wash and dehydrate. The optimum pH value range of the environmentally friendly bio-enzyme preparation is 7 to 8 to ensure the activity of the environmentally friendly bio-enzyme preparation and the treatment effect.

[0048] Environmentally friendly bio-enzymes include the following components by weight: 30% to 40% cellulase, 20% to 30% protease, 10% to 20% auxiliary enzymes and 10% to 20% auxiliary additives. Aiming at the characteristics of ultra-fine wool fibers, such as small fiber fineness, large surface area and easy damage, the synergistic effect of cellulase and protease can effectively remove impurities and residues on the fiber surface while maintaining the integrity and softness of the fiber. Other auxiliary enzymes and auxiliary additives are used to enhance the stability and treatment effect of enzyme preparations to ensure that no unnecessary damage is caused to wool fibers during the treatment process.

[0049] Auxiliary enzymes include one or more of lipase and catalase, and auxiliary additives include metal ion chelators, sorbitol, surfactants, antioxidants and bovine serum albumin, wherein metal ion chelators, such as EDTA (ethylenediaminetetraacetic acid) or citrate, are used to stabilize the activity of the enzyme and prevent the adverse effects of metal ions on the enzyme; sorbitol can protect the enzyme from temperature and pH changes during the treatment process; surfactants, such as Tween series or Span series, can protect the enzyme from damage by surfactants; antioxidants, such as vitamin C or sodium thiosulfate, are used to protect the enzyme from oxidation damage; bovine serum albumin (BSA) can prevent the enzyme from inactivation or aggregation during the treatment process.

[0050] The manufacturers, components, and specific properties of the cellulase, protease, auxiliary enzymes, and auxiliary additives used in this example are described in detail as follows:

[0051] Cellulase: XWSM low-temperature washing cellulase produced by Shandong Dongchen Biotechnology Co., Ltd. is used, which can effectively decompose cellulose under low temperature conditions, reduce damage to wool fibers, and improve processing efficiency;

[0052] Protease: We use HSP type high-efficiency protease produced by Zhejiang Lvyuan Enzyme Preparation Co., Ltd. This enzyme preparation has high activity and stability, can effectively remove protein impurities on the surface of wool, and maintain the natural luster and softness of the fiber;

[0053] Auxiliary enzymes: Lipase is produced by Novozymes of Denmark. The catalase used is CAT1000 from Merck KGaA, Germany, which can decompose grease and peroxides respectively, further improving the cleanliness and durability of fabrics.

[0054] Auxiliary additives: Metal ion chelating agent is selected from Dowfax of Dow Chemical Company of the United States TM 2A1, sorbitol is selected from Sorbitol 70% from BASF of Germany, and surfactant is selected from Union Carbide of the United States 20. Vitamin C from Procter & Gamble, USA, was used as antioxidant, and BSA from Sigma-Aldrich, USA, was used as bovine serum albumin;

[0055] Environmentally friendly bio-enzymes are used to gently treat wool fibers to remove impurities, improve the feel and enhance the mechanical properties of the fibers. Although environmentally friendly bio-enzyme treatment may not fully achieve the significant effect of alkali shrinkage treatment in increasing density, it has the advantages of being more environmentally friendly and gentler, while being able to retain the natural excellent properties of wool fibers, such as softness and gloss, so that the shape and structural properties of ultra-fine wool fibers can achieve the expected shaping effect.

[0056] In the ultrasonic assisted dyeing process of S3, the grey fabric is washed and dyed using an ultrasonic dyeing machine.

[0057] The ultrasonic dyeing machine used is the Ultrasonic Dyeing Machine produced by Brückner Maschinenbau GmbH & Co. KG. Ultrasonic dyeing technology uses the powerful energy generated by the tiny bubbles generated by ultrasound when they burst in water to accelerate the diffusion and penetration of dye molecules, thereby improving dyeing efficiency. During the dyeing process, the ultrasonic frequency is controlled to be 20-40kHz, the dyeing temperature is 40-60℃, and the dyeing time is 10-30min, which are appropriately adjusted according to the type of dye and color depth.

[0058] When the ultrasonic dyeing machine is used to wash the grey cloth, the washing temperature is 30-40℃ and the ultrasonic power is 900w to reduce energy consumption and reduce damage to the fiber. The ultrasonic dyeing machine is used to dye the grey cloth at a temperature of 40-60℃, which is lower than the traditional dyeing temperature. Ultrasonic technology is used to accelerate the dyeing process. The ultrasonic power is 480-900w. The ultrasonic power is adjusted according to the thickness of the fabric and the depth of the color to enhance the penetration of the dye. The ultrasonic dyeing machine is used for washing and dyeing. The grey cloth can be washed without adding dye and can be dyed when adding dye. One machine has multiple uses, saving the cost of grey cloth dyeing and can shorten the dyeing time to 60%-70% of the traditional method to improve dyeing efficiency.

[0059] In the low-temperature drying and shaping of S4, a low-temperature drying and shaping machine is used to dry and shape the dyed grey cloth.

[0060] The low-temperature drying and shaping machine is the TD-1000 series dryer from Thermo Dynamics. This series of dryers is specially designed for sensitive fibers such as wool. It can provide precise temperature control and gentle air circulation to ensure that the dyed wool fabric is dried evenly and stably in a low-temperature environment, avoiding fiber shrinkage, deformation or color change that may be caused by high temperature.

[0061] During the drying process, the built-in humidity sensor and intelligent control system of the TD-1000 series dryer continuously monitors and adjusts the environment inside the machine to ensure appropriate humidity and avoid excessive drying that causes fiber embrittlement or static electricity. In addition, the machine is also equipped with an efficient heat recovery system that can effectively utilize heat energy, reduce energy consumption, and improve the environmental friendliness of the production process.

[0062] The drying temperature of the low-temperature dryer is 60-80℃. The specific temperature is adjusted according to the fiber type and dyeing depth of the wool, aiming to retain the natural softness and luster of the wool, while ensuring the durability and stability of the color. The dehydrated wool fabric is dried in a dryer with a needle plate. The speed of the fabric is 8-15m / min, the overfeed is 10-30%, and the stretching is 3-10% to maintain the softness and elasticity of the wool fiber. The drying time is 10-15min. The drying time is adjusted according to the thickness of the fabric and kept moderate to ensure that the fabric is evenly dried and avoid overdrying.

[0063] After drying, the grey cloth enters the shaping stage. The low-temperature drying shaping machine uses slight stretching and tension, combined with appropriate temperature, to make the wool fiber maintain its original softness while obtaining a certain shape stability, reducing the risk of deformation in subsequent processing. The shaping time is 10 to 20 minutes, ensuring that the wool grey cloth can maintain the ideal shape and size in subsequent cutting, sewing and other links.

[0064] The entire low-temperature drying and shaping process not only improves the quality of wool fabrics, but also reduces energy consumption and the use of chemicals by optimizing process parameters, which is in line with the modern textile industry's pursuit of environmental protection, high efficiency and sustainable development. At the same time, it also lays a good foundation for the subsequent processing of wool products and helps to improve the market competitiveness of the final products.

[0065] In the pre-shrinking process of S5, a fabric pre-shrinking and setting machine is used to pre-shrink the dried grey fabric.

[0066] The fabric pre-shrinking and shaping machine used is the YB-1800 fabric pre-shrinking and shaping machine produced by Yongsheng Machinery Co., Ltd. This model integrates advanced pre-shrinking and shaping technology, and is tailored for high-end wool fabrics. It can effectively control the shrinkage rate of the fabric while maintaining its original texture and shape. During the pre-shrinking process, the YB-1800 fabric pre-shrinking and shaping machine accurately controls the steam temperature, humidity and pressure to ensure that the wool fiber achieves the best pre-shrinking effect under mild conditions.

[0067] The fabric pre-shrinking and shaping machine uses a steam box for pre-shrinking treatment. The steam temperature is 105℃, the humidity is 70%, and the pressure is 0.7Mpa. This temperature can not only effectively promote the shrinkage of the fiber, but also avoid fiber damage caused by overheating. At the same time, the humidity control system inside the machine will maintain a suitable environmental humidity to help the fiber shrink and shape better. During the pre-shrinking treatment, the fabric passes through the hot and humid area of ​​the pre-shrinking machine at a steady speed. During this process, the machine's built-in tension control system will automatically adjust the tension according to the characteristics of the fabric to ensure that the fabric maintains uniform and moderate stretching during the pre-shrinking process, thereby achieving the ideal pre-shrinking effect. After the pre-shrinking is completed, the fabric immediately enters the shaping area, and through cooling and fixing treatment, the shrunken shape is stabilized, further reducing the shrinkage rate during subsequent wearing or washing.

[0068] In the finishing of S6, the pre-shrunk wool fabric is finished, including softening treatment and antistatic treatment.

[0069] Among them, the finishing method uses Soft'n'Care produced by Krupp of Germany. TM Finishing machine. Silicone softener is used for softening treatment and antistatic agent is used for antistatic treatment.

[0070] Silicone oil softener: KSG-150 silicone oil softener produced by Shin-Etsu Chemical Co., Ltd. of Japan is used. This product has excellent softness and durability, and can form a uniform protective film on the fiber surface, giving the garment a lasting soft feel.

[0071] Antistatic agent: DC-5700 antistatic agent produced by Dow Corning of the United States is used. This product can effectively reduce the resistance of the fiber surface, reduce the generation and accumulation of static electricity, and enable the garment to maintain good antistatic properties during wearing and washing.

[0072] In the finishing process, silicone softener and antistatic agent are first mixed in a certain proportion and then sprayed evenly on the dyed garments. Then, the garments are placed in Soft'n'Care TM Heat treatment is carried out in the finishing machine, with the temperature controlled at 120-150°C for about 5-10 minutes. Through heat treatment, silicone softener and antistatic agent can fully penetrate into the fiber to form a stable protective layer, thus giving the finished garment a lasting soft feel and antistatic properties.

[0073] In S7's garment production, pre-shrunk grey fabric is used for garment production.

[0074] Please refer to Figure 2 , garment making includes the following steps:

[0075] A1. Cutting of grey fabric: using automatic cutting machine to cut the grey fabric according to the design drawing;

[0076] A2, splicing and sewing, using automatic sewing machines to sew garments;

[0077] A3. Ironing and shaping: use the ironing machine to iron and shape the garments;

[0078] A4. Quality inspection and packaging: Carry out a comprehensive quality inspection on the garments, including size, appearance and sewing quality, and then use the packaging line to bag them.

[0079] In A1's grey fabric cutting, the automatic cutting machine is the AccuMark series cutting machine produced by Gerber Technology. Using a high-precision automatic cutting machine for cutting ensures the accuracy and consistency of the cut pieces, and marks the key information such as the stitching sequence, alignment point, pocket position, etc. on the cut pieces for subsequent sewing.

[0080] In the stitching and sewing of A2, the automatic sewing machine is the JUKIDDL-8700-2 automatic sewing machine produced by JUKI Corporation. Before stitching and sewing, the cut pieces can be pleated, embroidered and printed according to the design of the garment, which increases the layering and uniqueness of the garment.

[0081] In the A3 ironing and shaping process, the ironing and packaging process uses the 3D Garment Steamer produced by Shima Seiki of Japan. TMIroning machine. During the ironing process, the temperature of the ironing machine is controlled at 130-140℃ to ensure the flatness and crispness of the finished garment. The quality inspection includes a comprehensive inspection of the size, appearance and sewing quality to ensure that each piece of garment meets the quality standards. Finally, the automatic packaging line is used for bagging to ensure the hygiene and neatness of the finished garment.

[0082] When the ironing machine performs ironing, a three-dimensional human body model is used to simulate the human body's wearing state to perform three-dimensional ironing on the garment, so that the garment can better fit the curve of the human body, ensure that the garment is flat and crisp when worn, and improve the shape retention and wash resistance of the garment.

[0083] The ironing temperature of the ironing machine is 130-140℃. For normal ironing, choose 135℃ as the ironing temperature. This temperature can ensure that the wool fibers are properly heated without causing the fibers to shrink or deform due to excessive temperature. For particularly delicate wool fabrics, the temperature can be slightly lowered to 130℃; for coarse wool fabrics, it can be moderately increased to 140℃. The ironing machine turns on the steam function and adjusts to a medium steam volume. The right amount of steam can help the wool fibers restore their elasticity and reduce wrinkles. When ironing, spray the steam evenly on the clothes and gently slide the iron to ensure that the steam can fully penetrate the clothing fibers.

[0084] In A4's quality inspection and packaging, the packaging line model is PakMax 3000 produced by Packaging Solutions Inc. This line integrates automatic folding, sorting, packaging and packing functions, which can significantly improve the efficiency and quality of garment packaging.

[0085] The above processing equipment and treatment additives can also be replaced by similar products from other manufacturers on the market.

[0086] Embodiment 2:

[0087] The wool knitted garment manufacturing process of this embodiment is basically the same as the wool knitted garment manufacturing process of Example 1, except that: 70% ultrafine wool fiber, 20% natural environmentally friendly fiber and 10% polyester fiber are used, and a three-dimensional stereoscopic knitting machine is used to blend and manufacture the grey cloth. During the biological enzyme treatment, 30 to 120 m of the grey cloth is taken and put into a continuous enzyme treatment machine, and the weight bath ratio of the grey cloth to water is controlled to be 1:5 to 15, and then 40 g / L of an environmentally friendly biological enzyme preparation is added to the water, the speed of the grey cloth is controlled to be 100 to 350 m / min, the biological enzyme treatment temperature is 45°C, the biological enzyme treatment time is 40 min, and the steam temperature is 100°C, the humidity is 70%, and the pressure is 0.6 MPa during the pre-shrinking and shaping treatment.

[0088] Embodiment 3:

[0089] The wool knitted garment manufacturing process of this embodiment is basically the same as the wool knitted garment manufacturing process of Example 1, except that: 80% ultrafine wool fiber, 15% natural environmentally friendly fiber and 5% polyester fiber are used, and a three-dimensional stereoscopic knitting machine is used to blend and manufacture the grey cloth. During the biological enzyme treatment, 30 to 120 m of the grey cloth is taken and put into a continuous enzyme treatment machine, and the weight bath ratio of the grey cloth to water is controlled to be 1:5 to 15, and then 50 g / L of an environmentally friendly biological enzyme preparation is added to the water, the speed of the grey cloth is controlled to be 100 to 350 m / min, the biological enzyme treatment temperature is 45°C, the biological enzyme treatment time is 70 min, and the steam temperature is 95°C, the humidity is 70%, and the pressure is 0.4 MPa during the pre-shrinking and shaping treatment.

[0090] From the above, the main parameters changed in Examples 1 to 3 are the proportion of ultrafine wool fibers, the parameter changes of the bioenzyme treatment, and the steam temperature, humidity and pressure of the pre-shrinkage setting treatment. The change in the proportion of ultrafine wool fibers will affect the softness, warmth retention and environmental protection properties of the garment. A higher proportion of ultrafine wool fibers will increase the softness and warmth retention of the garment, but reduce the shaping ability of the garment fabric. The parameter changes of the bioenzyme treatment, such as the concentration of the enzyme preparation, the treatment temperature and time, affect the cleanliness, softness and glossiness of the fiber. Milder treatment conditions help to maintain the natural properties of the wool fiber, and its dosage needs to be adjusted according to the proportion of ultrafine wool fibers. Changes in the steam temperature, humidity and pressure of the pre-shrinkage setting treatment will affect the dimensional stability and shrinkage rate of the garment. Lower steam temperatures help to reduce fiber damage and maintain the dimensional stability and glossiness of the garment, but will reduce processing efficiency. The lower the proportion of ultrafine wool fibers, the higher the steam temperature can be to improve the efficiency of the pre-shrinkage setting treatment.

[0091] In order to test the effect of the change of ultrafine wool fiber proportion on the characteristics of finished garments, relevant experiments were conducted. Please refer to the table below for the experimental results:

[0092]

[0093] In order to test the effect of changes in enzyme treatment parameters on the properties of finished garments, relevant experiments were conducted. Please refer to the table below for the experimental results:

[0094]

[0095] In order to test the effect of changes in pre-shrinking and shaping processing parameters on the characteristics of finished garments, relevant experiments were conducted. Please refer to the table below for the experimental results:

[0096]

[0097] Combining the experimental results in the above three tables, we can conclude that:

[0098] During the knitting and weaving process, with the increase in the proportion of ultrafine wool fibers, the softness and warmth scores of the finished garments increased, but the environmental attribute score decreased slightly; in the bio-enzyme treatment, with the increase in enzyme concentration and time, the cleanliness, softness and glossiness scores of the finished garments all increased, so that the shape and structural properties of the ultrafine wool fibers achieved better shaping effects; in the pre-shrinking and shaping treatment, the reduction in steam temperature and pressure helps to improve the dimensional stability of the finished garments and reduce shrinkage.

[0099] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
