Description

TECHNICAL FIELD

[0001] The present application relates to a wool knitted garment manufacturing process. BACKGROUND

[0002] Wool fibers are widely used in the production of high-end textiles due to their excellent warmth retention, excellent elasticity, and good moisture absorption. 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 goods.

[0003] In traditional wool setting processes, various chemical reagents are often used to fix the shape and structure of wool fibers. Although these chemical reagents can achieve the desired setting effect to some extent, their use often accompanies damage to the wool fibers themselves. Chemical reagents can weaken the mechanical properties of wool fibers, leading to a decrease in strength and a decrease in elasticity, thereby affecting the durability and service life of the final product. In addition, the use of chemical reagents can also bring problems of environmental pollution and health risks. In the processing of wool, residual chemicals can cause irritation or allergic reactions to human skin, and these chemicals emitted into the environment during production can also have a negative impact on the ecosystem.

[0033] Embodiment 1:

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

[0035] S1, knitting, using 60% superfine wool fiber, 25% natural environment-friendly fiber and 15% polyester fiber to blend and weave the gray cloth;

[0036] S2, biological enzyme treatment, selecting an environmentally friendly biological enzyme to treat the gray cloth;

[0037] S3, ultrasonic wave assisted dyeing treatment, water washing and dyeing treatment of the gray fabric are performed;

[0038] S4, low-temperature drying and setting, drying and setting of the dyed gray fabric are performed;

[0039] S5, pre-shrinking treatment, pre-shrinking treatment of the dried gray fabric is performed;

[0040] S6, finishing, finishing of the pre-shrunk gray fabric is performed;

[0041] S7, garment making, garment making using the pre-shrunk gray fabric is performed.

[0042] In the knitting weaving of S1, a three-dimensional weaving machine is used to knit weave the gray fabric. The natural environment-friendly fiber is introduced, and the natural environment-friendly fiber includes one or more of bamboo fiber and regenerated cellulose fiber. These fibers not only have excellent moisture absorption and air permeability and comfort, but also can improve the environmental properties of the fabric. The microcapsule technology is added to wrap the tiny particles with functions such as warmth, antibacterial, and odor resistance in the fiber. Through friction, the effective components are released to give the fabric more functionality.

[0043] The three-dimensional weaving machine uses a 3D Weaving Machine 8000 type three-dimensional weaving machine produced by Stäubli Textile Machinery Company, which can realize complex three-dimensional structure weaving and is suitable for the production of various blended fabrics.

[0044] By introducing the three-dimensional weaving technology in the knitting weaving of S1, the gray fabric forms more layers of air layer in structure, further improves the warmth retention performance, and maintains the lightness and softness of the gray fabric. The longitudinal density of the three-dimensional weaving machine is 105 stitches / inch, and the transverse density is 84 stitches / inch. On the basis of the original, the longitudinal and transverse densities are each increased by 5% to enhance the tightness and warmth retention of the gray fabric. The knitting tension of the three-dimensional weaving machine is 50-60 cN, and the tension is moderately adjusted to ensure uniformity of the loop structure, thereby reducing the risk of shedding.

[0045] In the biological enzyme treatment of S2, a continuous enzyme treatment machine is used to treat the gray fabric with environmentally friendly biological enzymes.

[0046] The continuous enzyme treatment machine uses a LH-1000 type continuous enzyme treatment machine produced by Shanghai Leading Navigation Biotechnology Co., Ltd.

[0047] When the biological enzyme is used, the 30-120 m of the grey cloth is put into the continuous enzyme treatment machine, and the weight bath ratio of the grey cloth and water is controlled to be 1:5-15, then the 30 g / L of the environment-friendly biological enzyme preparation is added into the water, the speed of the grey cloth is controlled to be 100-350 m / min, the biological enzyme treatment temperature is 50℃, the biological enzyme treatment time is 20 min, the treatment time is adjusted according to the activity of the environment-friendly biological enzyme preparation and the thickness of the grey cloth, the thick grey cloth has a long time, the thin grey cloth has a short time, and after the treatment, the water is drained, washed and dehydrated, and the pH value of the environment-friendly biological enzyme preparation is in the optimum range of 7-8, so as to ensure the activity of the environment-friendly biological enzyme preparation and the treatment effect.

[0048] The environment-friendly biological enzyme includes the following components in the mass proportion: 30%-40% of cellulase, 20%-30% of protease, 10%-20% of auxiliary enzymes and 10%-20% of auxiliary additives. According to the characteristics of the superfine wool fiber, such as small fiber fineness, large surface area and easy damage, through the synergistic effect of the cellulase and the protease, the impurities and residues on the fiber surface are effectively removed, and the integrity and softness of the fiber are maintained. The other auxiliary enzymes and auxiliary additives are used to enhance the stability and treatment effect of the enzyme preparation, so as to ensure that the wool fiber is not damaged unnecessarily during the treatment process.

[0049] The auxiliary enzymes include one or more of lipase and catalase, and the auxiliary additives include metal ion chelating agent, sorbitol, surfactant, antioxidant and bovine serum albumin. The metal ion chelating agent, such as EDTA (ethylenediaminetetraacetic acid) or citrate, is used to stabilize the activity of the enzyme and prevent the adverse effect of metal ions on the enzyme; the sorbitol can protect the enzyme from the influence of temperature and pH change during the treatment process; the surfactant, such as the Tween series or the Span series, can protect the enzyme from the damage of the interfacial active agent; the antioxidant, such as vitamin C or sodium thiosulfate, is used to protect the enzyme from the damage of oxidation; and the bovine serum albumin (BSA) can prevent the enzyme from inactivation or aggregation during the treatment process.

[0050] The production manufacturers, component ingredients and specific properties of the cellulase, protease, auxiliary enzymes and auxiliary additives used in the embodiment are described as follows:

[0051] The cellulase: the XWSM type low-temperature washing cellulase produced by Shandong Dongchen Biotechnology Co., Ltd. can effectively decompose cellulose under low-temperature conditions, reduce the damage to the wool fiber, and improve the treatment efficiency;

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

[0053] Auxiliary enzymes: lipase is selected from Lipolase® produced by Novozymes Denmark, catalase is selected from CAT1000 produced by Merck Group Germany, which can respectively decompose oil and peroxide, further improving the cleanliness and durability of the fabric;

[0054] Auxiliary additives: metal ion chelating agent is selected from Dowfax™ 2A1 produced by Dow Chemical Company USA, sorbitol is selected from Sorbitol 70% produced by BASF Germany, surfactant is selected from Tween® 20 produced by Union Carbide USA, antioxidant is selected from vitamin C produced by Procter &Gamble USA, and bovine serum albumin is selected from BSA produced by Sigma-Aldrich USA;

[0055] The environmentally friendly bio-enzyme is used to treat the wool fiber mildly, remove impurities, improve the hand feeling and enhance the mechanical properties of the fiber. Although the environmentally friendly bio-enzyme treatment may not completely achieve the significant effect of density improvement as the alkali shrinking treatment, it has the advantages of being more environmentally friendly and more mild, and can preserve the natural excellent properties of the wool fiber, such as softness and gloss, so that the shape and structural properties of the superfine wool fiber can achieve the expected setting effect.

[0056] In the ultrasonic assisted dyeing process of S3, the ultrasonic dyeing machine is used to wash and dye the gray fabric.

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

[0058] When the ultrasonic dyeing machine is used to wash the gray fabric, the washing temperature is 30-40℃ and the ultrasonic power is 900w, so as to reduce the energy consumption and damage to the fiber. When the ultrasonic dyeing machine is used to dye the gray fabric, the dyeing temperature is 40-60℃, which is lower than the traditional dyeing temperature. The ultrasonic technology is used to accelerate the dyeing process, and the ultrasonic power is 480-900w, which is adjusted according to the thickness of the fabric and the depth of the color, so as to enhance the penetration of the dye. The ultrasonic dyeing machine is used for washing and dyeing, which can clean the gray fabric without adding dye and can dye the gray fabric with dye. It is a machine with multiple functions, which can save the cost of gray fabric dyeing and shorten the dyeing time to 60%-70% of the traditional method, so as to improve the dyeing efficiency.

[0059] In the low-temperature drying and setting of S4, a low-temperature drying and setting machine is used to dry and set the dyed gray fabric.

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

[0061] During the drying process, the humidity sensor and intelligent control system built into the TD-1000 series dryer continuously monitor and adjust the machine environment to ensure proper humidity and avoid excessive drying that may cause fiber brittleness or static electricity. In addition, the machine is also equipped with a high-efficiency 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°C, and the specific temperature is adjusted according to the fiber type and dyeing depth of the wool, aiming to preserve the natural softness and luster of the wool while ensuring the durability and stability of the color. The dyed wool gray fabric is dried on the dryer with a needle board at a speed of 8-15 m / min, with a feed of 10-30% and a tentering of 3-10% to maintain the softness and elasticity of the wool fibers. The drying time is 10-15 min, which is adjusted according to the thickness of the fabric to maintain a moderate drying time and ensure uniform drying of the fabric, avoiding over-drying.

[0063] After drying, the gray fabric enters the setting stage. The low-temperature drying and setting machine uses slight stretching and tension combined with appropriate temperature to make the wool fibers maintain their original softness while gaining certain form stability, reducing the risk of deformation in subsequent processing. The setting time is 10-20 min to ensure that the wool gray fabric can maintain the ideal form and size during subsequent cutting, sewing, and other processes.

[0064] The entire low-temperature drying and setting process not only improves the quality of the wool gray fabric, but also reduces energy consumption and the use of chemicals by optimizing process parameters, meeting the modern textile industry's pursuit of environmental friendliness, efficiency, and sustainable development. At the same time, this also lays a good foundation for the subsequent processing of wool products, helping to improve the market competitiveness of the final product.

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

[0066] The fabric preshrinking and setting machine uses YB-1800 fabric preshrinking and setting machine produced by Yongsheng Machinery Co., Ltd. This machine integrates advanced preshrinking and setting technology, is specially designed for high-end wool fabric, can effectively control the shrinkage of the fabric, and at the same time maintain the original texture and shape of the fabric. During the preshrinking process, the YB-1800 fabric preshrinking and setting machine controls the steam temperature, humidity and pressure accurately to ensure that the wool fiber reaches the best preshrinking effect under mild conditions.

[0067] The fabric preshrinking and setting machine uses a steam box for preshrinking treatment, with a steam temperature of 105°C, a humidity of 70%, and a pressure of 0.7Mpa. This temperature can effectively promote the shrinkage of the fiber and avoid fiber damage caused by overheating. At the same time, the humidity control system inside the machine will maintain a suitable environment humidity to help the fiber shrink and set better. During the preshrinking process, the fabric passes through the humid and hot area of the preshrinking machine at a stable speed. During this process, the built-in tension control system of the machine will automatically adjust the tension according to the characteristics of the fabric to ensure that the fabric maintains uniform and moderate stretching during the preshrinking process, thereby achieving the ideal preshrinking effect. After preshrinking, the fabric immediately enters the setting area, and through cooling and fixing treatment, the shape after shrinkage is stabilized, further reducing the shrinkage rate in the subsequent wearing or washing process.

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

[0069] Among them, the finishing uses Soft'n'Care™ finishing machine produced by Krupp Company of Germany. The softening treatment uses silicone softener, and the antistatic treatment uses antistatic agent.

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

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

[0072] In the finishing process, first mix the silicone softener and antistatic agent in a certain proportion, then evenly spray it on the dyed fabric. Then, put the fabric into the Soft'n'Care™ finishing machine for heat treatment, the temperature is controlled at 120-150℃, and the time is about 5-10min. Through heat treatment, the silicone softener and antistatic agent can fully penetrate into the fiber, forming a stable protective layer, thus giving the fabric a lasting soft feel and antistatic performance.

[0073] In the garment making of S7, the fabric treated by finishing is used for garment making.

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

[0075] A1, fabric cutting, using automatic cutting machine to cut fabric according to design drawing;

[0076] A2, splicing sewing, using automatic sewing machine to distribute garment sewing;

[0077] A3, ironing and shaping, using ironing machine to iron and shape the garment;

[0078] A4, quality inspection and packaging, the garment is subjected to comprehensive quality inspection, including size, appearance and sewing quality, and then packaged with packaging line.

[0079] In the fabric cutting of A1, the automatic cutting machine is AccuMark series cutting machine produced by Gerber Technology. Using high-precision automatic cutting machine for cutting, to ensure the accuracy and consistency of the cutting piece, mark the key information such as sewing order, alignment point, pocket position, etc. on the cutting piece, to facilitate subsequent sewing.

[0080] In the splicing sewing of A2, the automatic sewing machine is JUKI DDL-8700-2 type automatic sewing machine produced by JUKI Corporation. Before splicing sewing, the cutting piece can be subjected to pleating, embroidery and printing according to the design of the garment, to increase the level and uniqueness of the garment.

[0081] In the ironing and shaping of A3, ironing and packaging use 3D Garment Steamer™ ironing machine produced by Japan Shima Seiki Company. The ironing machine controls the temperature at 130-140℃ during ironing, to ensure the flatness and crispness of the garment. Quality inspection includes comprehensive inspection of size, appearance and sewing quality, to ensure that each garment meets the quality standard. Finally, use automatic packaging line for bagging, to ensure the hygiene and neatness of the garment.

[0082] When the ironing machine is used for ironing, a three-dimensional mannequin is used to simulate the wearing state of the human body to iron the garment in three dimensions, so that the garment can better fit the curved shape of the human body, ensure the flatness and crispness of the garment when worn, and improve the shape retention and wash resistance of the garment.

[0083] The ironing temperature of the ironing machine is 130-140℃, and 135℃ is selected as the ironing temperature during normal ironing. This temperature can ensure that the wool fibers are properly heated, and the fibers will not shrink or deform due to excessive temperature. For particularly delicate wool fabrics, the temperature can be slightly reduced to 130℃; while for thicker wool fabrics, the temperature can be increased to 140℃. The steam function of the ironing machine is turned on and adjusted to medium steam. The appropriate amount of steam can help the wool fibers regain elasticity and reduce wrinkles. When ironing, the steam should be evenly sprayed on the clothes, and the iron should be gently slid to ensure that the steam can fully penetrate the fibers of the clothes.

[0084] In the quality inspection and packaging of A4, the packaging assembly line model is PakMax 3000 produced by Packaging Solutions Inc. The assembly line integrates automatic folding, sorting, packaging and packaging 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 other manufacturers' products of the same kind.

[0086] Example 2:

[0087] The wool knitwear manufacturing process of this embodiment is basically the same as that of Example 1, except that 70% super fine wool fiber, 20% natural environmentally friendly fiber and 10% polyester fiber are used, a three-dimensional knitting machine is used to mix and weave the gray cloth, 30-120m of the gray cloth is put into a continuous enzyme treatment machine during enzyme treatment, and the weight bath ratio of the gray cloth to water is controlled to be 1:5-15, then 40g / L of environmentally friendly bio-enzyme preparation is added to the water, the speed of the gray cloth is controlled to be 100-350m / min, the bio-enzyme treatment temperature is 45℃, the bio-enzyme treatment time is 40min, the steam temperature during preshrinking and setting is 100℃, the humidity is 70%, and the pressure is 0.6MPa.

[0088] Example 3:

[0089] The wool knitted garment manufacturing process of the embodiment is basically the same as that of Example 1, the difference is that 80% super fine wool fiber, 15% natural environment-friendly fiber and 5% polyester fiber are used, three-dimensional weaving machine is used for blending and weaving the gray cloth, when the biological enzyme treatment is carried out, 30-120m of the gray cloth is taken into the continuous enzyme treatment machine, and the weight bath ratio of the gray cloth and water is controlled to be 1:5-15, then 50g / L of environment-friendly biological enzyme preparation is added into the water, the speed of the gray cloth is controlled to be 100-350m / min, the biological enzyme treatment temperature is 45°C, the biological enzyme treatment time is 70min, the steam temperature of the preshrinking and setting treatment is 95°C, the humidity is 70%, and the pressure is 0.4MPa.

[0090] From the above, the main change parameters in Examples 1-3 are the proportion of super fine wool fiber, the parameter changes of biological enzyme treatment and the steam temperature, humidity and pressure of preshrinking and setting treatment, the change of the proportion of super fine wool fiber will affect the softness, warmth and environmental protection property of the garment, higher proportion of super fine wool fiber will increase the softness and warmth of the garment, but reduce the modeling ability of the garment fabric. The parameter changes of biological enzyme treatment, such as enzyme preparation concentration, treatment temperature and time, affect the cleanliness, softness and luster of the fiber. The milder treatment conditions are helpful to maintain the natural properties of wool fiber, and the dosage needs to be adjusted according to the proportion of super fine wool fiber. The changes of steam temperature, humidity and pressure of preshrinking and setting treatment will affect the dimensional stability and shrinkage of the garment. Lower steam temperature helps to reduce fiber damage, maintain the dimensional stability and luster of the garment, but will reduce the processing efficiency, and the lower the proportion of super fine wool fiber, the higher the steam temperature can improve the preshrinking and setting treatment efficiency.

[0091] In order to test the influence of the change of the proportion of super fine wool fiber on the characteristics of the garment, the related experiment is carried out, and the experimental results are shown in the following table:

[0092]

[0093] In order to test the influence of the change of the parameter of biological enzyme treatment on the characteristics of the garment, the related experiment is carried out, and the experimental results are shown in the following table:

[0094]

[0095] In order to test the influence of the change of the parameter of preshrinking and setting treatment on the characteristics of the garment, the related experiment is carried out, and the experimental results are shown in the following table:

[0096]

[0097] From the above three tables, it can be concluded that:

[0098] In the process of knitting, with the increase of the proportion of superfine wool fiber, the softness and warmth of the garment are improved, but the environmental property score is slightly decreased; in the biological enzyme treatment, with the increase of enzyme concentration and time, the cleanliness, softness and luster of the garment are improved, so that the shape and structure of the superfine wool fiber are better shaped; in the preshrunk and shaped treatment, the reduction of steam temperature and pressure helps to improve the size stability of the garment and reduce the shrinkage.

[0099] The above merely describes some embodiments of the present application. For those skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which are within the protection scope of the present application.
