Description

Technical Field

[0001] This invention belongs to the field of glove manufacturing technology, and in particular relates to a method for manufacturing imitation mink fur gloves. Background Technology

[0002] Faux mink gloves are highly sought after for their soft, delicate touch, excellent warmth, and attractive appearance, making them popular for everyday wear, fashion styling, and light protection, leading to a continuously growing market demand. Their core competitiveness lies in replicating the fluffiness, softness, and visual texture of natural mink fur, while also ensuring durability and comfort, thus meeting consumers' dual needs for "quality and practicality."

[0003] Currently, the production of imitation mink fur gloves is mostly based on improvements to the manufacturing processes of traditional protective gloves (nitrile, latex, and polyurethane gloves). The core processes still revolve around yarn weaving, impregnation with coagulant, dipping in adhesive, drying, and demolding. In existing technologies, achieving the imitation mink fur effect mainly relies on the selection of reverse-fur yarn or the addition of a small amount of softener to conventional adhesives, lacking targeted process and formulation optimization design.

[0004] However, existing technologies have several shortcomings in the production of imitation mink gloves: First, the adhesive and the suede yarn have poor compatibility. Traditional glove adhesives primarily focus on increasing strength and abrasion resistance, without adding specific softening modifiers, resulting in gloves that feel stiff after impregnation and fail to replicate the delicate and soft texture of mink fur. Second, the impregnation and setting processes lack specificity. Existing processes use excessively thick adhesive layers (usually over 0.2mm) and high drying temperatures (above 60℃), which easily compacts the fluffy structure of the suede yarn, damaging the appearance of the imitation mink fur and resulting in insufficient simulation. Third, it is difficult to balance warmth and durability; relying solely on the fluffiness of the suede yarn for warmth is insufficient. The adhesive layer and yarn are not firmly bonded, which can easily lead to hair loss and adhesive layer peeling after long-term wear. At the same time, a thick adhesive layer will reduce the heat retention effect. Fourth, the process lacks versatility. Different base adhesives (nitrile rubber, natural latex, polyurethane) have different softness characteristics. The existing process has not optimized the adhesive formula and process parameters for the needs of imitation mink fur, resulting in large differences in the texture of imitation mink fur gloves made of different materials, making it difficult to form a stable product quality. Fifth, there is a lack of dedicated shaping treatment. The existing process often omits combing and hot air shaping steps, resulting in messy fiber direction of the reverse yarn, which cannot form a uniform and fluffy imitation mink fur appearance, further reducing the visual and tactile simulation of the product.

[0005] Therefore, in response to the problems existing in the production of imitation mink gloves, such as stiff feel, low simulation, insufficient warmth and durability, and poor process compatibility, there is an urgent need to develop a method for producing imitation mink gloves that accurately reproduces the texture of mink fur through a collaborative design of "targeted rubber modification + suitable process parameters + special shaping treatment," while taking into account warmth, durability, and process compatibility, in order to meet the market demand for high-quality imitation mink gloves. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned technical problems by providing a method for manufacturing imitation mink gloves.

[0007] In view of this, the present invention provides a method for manufacturing imitation mink fur gloves, comprising the following steps: S1, Glove core preparation and mold making: The glove core is woven from reverse yarn and stretched and fitted onto the hand mold to ensure that the glove core fits the surface of the hand mold without wrinkles. S2, Coagulant Immersion Treatment: Immerse the molded glove core into the coagulant solution, remove it and drain off excess solution from the surface; S3, preparation of imitation mink fur adapted rubber compound: mix the base rubber, additives and softening modifier in proportion, stir evenly to form a uniformly dispersed rubber compound system; when the rubber compound system needs to improve performance through cross-linking, a vulcanizing agent also needs to be added; S4, Uniform Impregnation: The glove core treated with coagulant is immersed in the adhesive material, and the impregnation parameters are controlled to make the adhesive layer uniformly cover the surface of the glove core. S5, Faux Mink Fur Texture Shaping: The surface of the glued gloves is combed to comb the direction of the reverse fur yarn fibers, and then preliminary shaping is performed; S6, Segmented Drying: The yarn is dried in stages, first at low temperature to remove volatile components, then at high temperature to allow the adhesive layer to initially cure. Temperature is controlled during the drying process to prevent deformation of the fuzzy yarn. S7, vulcanization treatment: When the performance of the rubber system needs to be improved through cross-linking, the gloves after preliminary curing are vulcanized to make the rubber macromolecules cross-link to form a three-dimensional network structure. S8, Soaking and Secondary Drying: Soak the gloves in a washing tank to remove residual impurities, and then dry them at a low temperature to the preset moisture content to keep the suede yarn soft and fluffy; S9, Demolding and Inspection: Demold the gloves after they have cooled, and then inspect and screen the qualified products.

[0008] Furthermore, in step S1, the reverse yarn is a blended yarn consisting of 43-63 parts wool fiber, 22-33 parts acrylic fiber, 10-22 parts polyester fiber, and 1-5 parts conductive fiber; the knitting is performed using a 7-needle, 8-needle, 10-needle, 13-needle, 17-needle, or 18-needle computerized knitting machine.

[0009] Furthermore, in step S2, the coagulant solution comprises the following parts by weight: 93-96 parts methanol, 3-5 parts calcium nitrate, and 0.6-1.8 parts glacial acetic acid, or 93-96 parts methanol and 3-5 parts calcium chloride; the immersion time in the coagulant is 8-22 seconds.

[0010] Furthermore, in step S3, the softening modifier is a complex of silicone softener and lanolin, comprising 63-85 parts by weight of silicone softener and 22-43 parts by weight of lanolin; the amount of softening modifier added to the adhesive is 3-5 parts.

[0011] Furthermore, in step S3, the viscosity of the rubber compound is controlled to be 330-850 mPa·s; the base rubber is one of nitrile rubber, natural latex or polyurethane base rubber; the vulcanizing agent is sulfur; and the additives include zinc oxide, antioxidants and dispersants.

[0012] Furthermore, in step S4, the hand mold rotation speed is 22-43 r / min during the impregnation process, the impregnation environment is a closed space, the temperature of the glue tank is controlled at 22-33℃, and the thickness of the glue layer is controlled at 0.05-0.17mm to avoid covering the surface fluff of the suede yarn.

[0013] Furthermore, in step S5, a combing machine is used for surface combing, with a combing distance of 0.6-1.0 mm and a combing speed of 5-10 m / min; the initial shaping is done with hot air shaping at a temperature of 43-63℃ for 5-10 minutes.

[0014] Furthermore, in step S6, the low-temperature drying temperature is 45-55℃ and the drying time is 28-37 minutes; during high-temperature drying, the drying temperature for nitrile gloves and latex gloves is 85-90℃ and the drying time is 22-33 minutes, while the drying temperature for polyurethane gloves is 90-100℃ and the drying time is 43-63 minutes.

[0015] Furthermore, in step S7, the vulcanization treatment adopts steam vulcanization, with a vulcanization temperature of 100-122℃, a vulcanization time of 17-33 minutes, and humidity controlled at 65-75% during the vulcanization process.

[0016] Furthermore, in step S8, the soaking water temperature is 28-37℃ and the soaking time is 8-17 minutes; the secondary drying temperature is 43-50℃, and the final moisture content of the gloves is controlled at 3-5% to ensure the soft and fluffy texture of the suede yarn.

[0017] The beneficial effects of this invention are: This invention, through the design of soft modified rubber and targeted combing and shaping, retains the fluffy structure of the reverse wool yarn while optimizing the touch through a softening modifier. It solves the problems of stiff feel and low simulation of traditional gloves, making the gloves highly similar to natural mink fur in terms of visual fluffiness and tactile delicacy. Detailed Implementation

[0018] The technical solutions in the embodiments of this application will be clearly described below. Obviously, the described embodiments are only some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application are within the scope of protection of this application.

[0019] A method for manufacturing imitation mink fur gloves includes the following steps: S1, Glove core preparation and mold making: The glove core is woven from reverse yarn and stretched and fitted onto the hand mold to ensure that the glove core fits the surface of the hand mold without wrinkles. S2, Coagulant Immersion Treatment: Immerse the molded glove core into the coagulant solution, remove it and drain off excess solution from the surface; S3, preparation of imitation mink fur adapted rubber compound: mix the base rubber, additives and softening modifier in proportion, stir evenly to form a uniformly dispersed rubber compound system; when the rubber compound system needs to improve performance through cross-linking, a vulcanizing agent also needs to be added; S4, Uniform Impregnation: The glove core treated with coagulant is immersed in the adhesive material, and the impregnation parameters are controlled to make the adhesive layer uniformly cover the surface of the glove core. S5, Faux Mink Fur Texture Shaping: The surface of the glued gloves is combed to comb the direction of the reverse fur yarn fibers, and then preliminary shaping is performed; S6, Segmented Drying: The yarn is dried in stages, first at low temperature to remove volatile components, then at high temperature to allow the adhesive layer to initially cure. Temperature is controlled during the drying process to prevent deformation of the fuzzy yarn. S7, vulcanization treatment: When the performance of the rubber system needs to be improved through cross-linking, the gloves after preliminary curing are vulcanized to make the rubber macromolecules cross-link to form a three-dimensional network structure. S8, Soaking and Secondary Drying: Soak the gloves in a washing tank to remove residual impurities, and then dry them at a low temperature to the preset moisture content to keep the suede yarn soft and fluffy; S9, Demolding and Inspection: Demold the gloves after they have cooled, and then inspect and screen the qualified products.

[0020] This invention, through the design of a soft modified adhesive and targeted combing and shaping, retains the fluffy structure of the suede yarn while optimizing the feel through a softening modifier. This solves the problems of stiffness and low simulation in traditional gloves, making the gloves highly similar to natural mink fur in terms of visual fluffiness and tactile delicacy. In addition, the uniform impregnation process ensures that the adhesive layer is thin and firm, avoiding problems such as shedding and adhesive layer peeling. The segmented drying and secondary low-temperature drying process ensures that the adhesive layer is cured without damaging the fluffiness of the suede yarn, balancing warmth and durability, and resolving the contradiction of "difficulty in balancing warmth and durability" in traditional processes.

[0021] In the example of this application, in step S1, the reverse yarn is a blended yarn of 43-63 parts wool fiber, 22-33 parts acrylic fiber, 10-22 parts polyester fiber, and 1-5 parts conductive fiber; the knitting is done using a 7-needle, 8-needle, 10-needle, 13-needle, 17-needle, or 18-needle computerized knitting machine.

[0022] Wool fibers (43-63 parts) provide a natural soft texture and warmth, acrylic fibers (22-33 parts) enhance fluffiness and abrasion resistance, polyester fibers (10-22 parts) improve structural stability, and conductive fibers (1-5 parts) eliminate the problem of static electricity attracting dust. The blend of these four fibers solves the defects of single fiber materials that are "soft but not durable, fluffy but prone to static electricity". At the same time, the addition of conductive fibers prevents the gloves from attracting hair and dust due to static electricity when worn, thus improving the user experience.

[0023] In the example of this application, in step S2, the coagulant solution comprises the following parts by weight: 93-96 parts methanol, 3-5 parts calcium nitrate, and 0.6-1.8 parts glacial acetic acid, or 93-96 parts methanol and 3-5 parts calcium chloride; the immersion time in the coagulant is 0.1-22 seconds.

[0024] The formula, which is based on methanol and supplemented with calcium nitrate / calcium chloride and glacial acetic acid, ensures impermeability (prevents the rubber from seeping through the glove core) while reducing the damage of the coagulant to the reverse yarn fibers, thus solving the problem that traditional coagulant formulas can easily cause the yarn to harden.

[0025] In the example of this application, in step S3, the softening modifier is a complex of silicone softener and lanolin, comprising 63-85 parts of silicone softener and 22-43 parts of lanolin by weight; the amount of softening modifier added to the adhesive is 3-5 parts.

[0026] Silicone softener (63-85 parts) has excellent lubricity and can significantly reduce the coefficient of friction of the adhesive layer. Lanolin (22-43 parts) has good compatibility with suede yarn (containing wool fibers) and can enhance the soft touch of the yarn and the adhesive layer. The combination of the two solves the problem of "soft but easy to fall off" of a single softener.

[0027] In the example of this application, in step S3, the viscosity of the rubber compound is controlled to be 330-850 mPa·s; the base rubber is one of nitrile rubber, natural latex or polyurethane base rubber; the vulcanizing agent is sulfur; and the additives include zinc oxide, antioxidants and dispersants.

[0028] The viscosity range of 330-850 mPa·s is suitable for the fluffy characteristics of suede yarn, ensuring that the adhesive has sufficient fluidity to adhere evenly to the surface of the glove core, while avoiding the adhesive layer being too thin due to excessively low viscosity or the yarn fluffiness being compacted due to excessively high viscosity, ensuring that the adhesive layer thickness is uniform and does not damage the imitation mink fur shape. In the example of this application, in step S4, the hand mold rotation speed is 22-43 r / min during the impregnation process, the impregnation environment is a closed space, the temperature of the glue tank is controlled at 22-33℃, and the thickness of the glue layer is controlled at 0.05-0.17mm to avoid covering the surface fluff of the suede yarn.

[0029] The hand mold speed of 22-43r / min and the glue tank temperature of 22-33℃ reduce the impact of the glue on the suede yarn and prevent the yarn fibers from being compacted; the thin glue layer design of 0.05-0.17mm only covers the surface of the yarn without wrapping the fluff, solving the problem of loss of fluffiness caused by traditional thick glue layers.

[0030] In the example of this application, in step S5, a combing machine is used for surface combing, with a combing machine needle pitch of 0.6-1.0 mm and a combing speed of 5-10 m / min; the initial shaping is done with hot air shaping at a temperature of 43-63℃ for 5-10 minutes.

[0031] A combing machine with a needle spacing of 0.6-1.0mm and a combing speed of 5-10m / min can gently comb the suede yarn fibers, making the messy fibers tend to be uniform in direction, forming a uniform and fluffy appearance, solving the problem of insufficient simulation caused by messy fibers in traditional processes; the combing process can remove excess fuzz from the yarn surface, making the glove surface both fluffy and neat; hot air setting further improves the bonding stability between the yarn and the adhesive layer, preventing fuzz from falling off after combing, balancing appearance neatness and durability; hot air setting temperature of 43-63℃ and setting time of 5-10 minutes fix the fiber shape after combing without damaging the yarn fibers, preventing the fibers from scattering during wear, and ensuring the long-lasting appearance of faux mink fur.

[0032] In the example of this application, in step S6, the low-temperature drying temperature is 45-55℃ and the drying time is 28-37 minutes; during high-temperature drying, the drying temperature for nitrile gloves and latex gloves is 85-90℃ and the drying time is 22-33 minutes, while the drying temperature for polyurethane gloves is 90-100℃ and the drying time is 43-63 minutes.

[0033] Low-temperature drying at 5-55℃ can slowly remove volatile components, avoiding yarn fiber shrinkage and adhesive layer cracking caused by high-temperature rapid drying; differentiated high-temperature drying parameters are designed for different base adhesives (nitrile / latex 85-90℃ / 22-33 minutes, polyurethane 90-100℃ / 43-63 minutes) to ensure that the adhesive layer is fully cured without damaging the fluffiness of the suede yarn; the gentle drying process avoids yellowing and hardening of the suede yarn, maintains the natural softness and color of the yarn, and ensures that the visual and tactile texture of the gloves is close to that of natural mink fur.

[0034] In the example of this application, in step S7, the vulcanization treatment adopts steam vulcanization, the vulcanization temperature is 100-122℃, the vulcanization time is 17-33 minutes, and the humidity is controlled at 65-75% during the vulcanization process.

[0035] A vulcanization temperature of 100-122℃ and a vulcanization time of 17-33 minutes allow for full cross-linking of the macromolecules in nitrile / latex rubber compounds, improving the wear resistance and tensile strength of the rubber layer and solving the problem of stiff rubber layer caused by excessively high vulcanization parameters in traditional methods.

[0036] In the example of this application, in step S8, the soaking water temperature is 28-37℃ and the soaking time is 8-17 minutes; the secondary drying temperature is 43-50℃, and the final moisture content of the gloves is controlled at 3-5% to ensure the soft and fluffy texture of the suede yarn.

[0037] A soaking water temperature of 28-37℃ and a soaking time of 8-17 minutes thoroughly remove residual methanol, coagulant components, and excess adhesive from the glove surface without damaging the suede yarn and adhesive layer. This avoids problems such as stiffness and odor caused by residual impurities, thus improving safety. A secondary low-temperature drying at 43-50℃ slowly removes the moisture after soaking, preventing yarn compaction and adhesive layer shrinkage caused by high-temperature drying. A final moisture content of 3-5% keeps the suede yarn moderately soft and fluffy, solving the problems of dry yarn and stiffness caused by over-drying in traditional methods. To verify the softness, warmth, faux mink fur simulation, and durability of the imitation mink fur gloves described in this invention, the following experiments were conducted. By comparing the performance differences between the minimum, intermediate, and maximum values ​​of the formula of this invention and those of imitation mink fur gloves made using traditional processes, it was demonstrated that the overall performance of the gloves of this invention is superior to that of the prior art.

[0038] Experimental sample preparation: Three key parameters that significantly influence the texture of faux mink fur were selected for this invention. Three groups of experimental samples (denoted as F1, F2, and F3) were set up according to the minimum, median, and maximum values. At the same time, a control group sample (denoted as CK) was prepared using traditional methods. All samples used polyurethane as the base adhesive (suitable for the softness requirements of faux mink fur and highly representative). Other non-critical process parameters (such as coagulant formulation and combing parameters) remained consistent to ensure the uniqueness of variables.

[0039] Core parameter settings: F1: The addition amount of softening modifier is 1 part by weight, the thickness of the adhesive layer is 0.05 mm, and the secondary drying temperature is 43°C, which is the minimum value combination of the formulation of this invention.

[0040] F2: 2 parts by weight of softening modifier, 0.11 mm adhesive layer thickness, and 46°C secondary drying temperature, which is the intermediate combination of the formulation of this invention.

[0041] F3: The amount of softening modifier added is 3 parts by weight, the thickness of the adhesive layer is 0.17 mm, and the secondary drying temperature is 50°C, which is the maximum combination of the formulations of this invention.

[0042] CK: No softening modifier added, adhesive layer thickness 0.2mm, secondary drying temperature 60℃, prepared according to traditional impregnation process.

[0043] Sample preparation process: 1. All samples were made from a blended reverse wool yarn consisting of 50 parts wool fiber, 28 parts acrylic fiber, 22 parts polyester fiber, and 5 parts conductive fiber. The glove core was knitted using a 10-needle computer knitting machine. After molding, the glove was immersed in a coagulant (97 parts methanol, 2 parts calcium nitrate, and 1 part glacial acetic acid) for 17 seconds.

[0044] 2. The samples (F1 / F2 / F3) of this invention are prepared according to the corresponding parameters to form a sable fur-compatible adhesive compound (93 parts polyurethane base adhesive + 1.8 parts zinc oxide + 1 part antioxidant + 0.6 parts dispersant + softening modifier, with the viscosity controlled at 550 mPa·s); the traditional process sample (CK) adhesive compound does not contain a softening modifier and has the same viscosity of 550 mPa·s.

[0045] 3. After impregnation with resin, the samples of this invention are combed with a combing machine (needle spacing 0.8mm, speed 8m / min) and set with hot air (50℃ / 8 minutes); CK has no combing step and is directly air-dried and set.

[0046] 4. Segmented drying (low temperature 50℃ / 33 minutes, high temperature 93℃ / 50 minutes), polyurethane-based adhesive does not require vulcanization treatment, soaking and washing (33℃ / 12 minutes), secondary drying (corresponding set temperature / 28 minutes), after demolding, select defect-free samples for use.

[0053] Experimental methods: Softness test: 1. Test principle: The bending resistance of the palm area of ​​the glove is measured by a softness tester. The lower the bending resistance, the better the softness.

[0054] 2. Test conditions: room temperature 25℃, humidity 50%±5%, samples were equilibrated under these conditions for 24 hours in advance.

[0055] 3. Testing procedure: Fix the glove flat on the test table, select 3 different points on the palm, press the probe of the tester vertically down to a depth of 5mm at a speed of 10mm / s, record the maximum bending resistance at each point, test each sample 5 times, and take the average value (remove outliers).

[0056] Warmth retention test: 1. Test principle: The thermal resistance of the gloves is measured by a flat plate thermal insulation instrument. The higher the thermal resistance, the better the heat retention performance.

[0059] Simulation test of faux mink fur: Test principle: The evaluation is based on three dimensions: appearance and color, hair fluffiness, and touch, combined with colorimeter data and sensory scores.

[0060] Test steps: Color comparison: Use a colorimeter to measure the L*, a*, and b* values ​​of the sample and the standard mink hair, and calculate the color difference ΔE (the smaller the ΔE, the closer the colors are).

[0062] Sensory evaluation: Ten professional evaluators (with experience in identifying mink fur products) were invited to score the products on a scale of 1 to 10 (10 points is for complete consistency with standard mink fur). The scoring dimensions included color (3 points), fluffiness (3 points), and touch (4 points). The average score was calculated.

[0063] Durability test: 1. Test principle: The Martindale tester simulates the friction of daily wear of gloves to test the appearance integrity and softness retention rate after wear.

[0064] 2. Test procedure: Fix the sample on the wear-resistant machine fixture, put it in contact with the friction medium (cotton cloth), apply a pressure of 4.9N, and rub for 500 times. Observe whether the sample has any shedding or peeling of the adhesive layer. At the same time, test the softness after wear and calculate the softness retention rate (softness after wear / initial softness × 100%).

[0065] All experimental data were analyzed using Excel to calculate the mean ($\bar{x}$) and standard deviation (S).

[0078] Durability test results: F1: After 500 rubs, there is no hair loss or peeling of the adhesive layer, and the appearance is intact.

[0079] F2: After 500 rubs, there is no hair loss or peeling of the adhesive layer, and the appearance is intact.

[0080] F3: After 500 rubs, there is no hair loss or peeling of the adhesive layer, and the appearance is intact.

[0081] CK: Localized hair loss occurred (3 locations) after 500 rubs, with slight peeling at the edges of the adhesive layer, resulting in poor appearance integrity.

[0082] The above experimental results demonstrate that the present invention has the following effects: 1. Significant Softness Advantage: The initial softness of gloves F1, F2, and F3 of this invention is 27.4%, 38.7%, and 46.0% higher than that of the traditional process (CK), respectively. The softness retention rate after wear is over 92%, far exceeding the 76.7% of CK. The core reason is the synergistic effect of the softening modifier (organosilicon softener + lanolin) and the reverse yarn, which improves the material's flexibility. Furthermore, the thin adhesive layer design avoids the stiffness problem caused by the traditional thick adhesive layer.

[0083] 2. Superior warmth retention: The thermal resistance of the gloves of this invention is higher than that of traditional processes, with the maximum formula thermal resistance increased by 65.7%. Due to the fluffy structure of the reverse yarn forming an air insulation layer, combined with the optimized sealing of the adhesive layer by the softening modifier, heat conduction is reduced, and the warmth retention effect is significantly enhanced.

[0084] 3. Extremely high simulation of mink fur: The gloves of this invention have a smaller color difference ΔE and higher loft, with sensory scores exceeding 8 points. The maximum value formula is close to the texture of standard mink fur. The core reason is that the targeted combing and shaping process straightens the direction of the reverse-hair yarn fibers, the low-temperature drying and secondary drying processes preserve the yarn loft, and the softening modifier improves the delicate touch.

[0085] 4. Stable Durability: The gloves of this invention showed no shedding or peeling of the adhesive layer after 500 cycles of friction, while gloves made with traditional processes showed obvious damage. This is because the compatibility between the adhesive and the suede yarn is optimized, the adhesive layer is thin and evenly adhered, and it does not damage the yarn structure. At the same time, the vulcanization (for some materials) and setting processes enhance the bonding force between the adhesive layer and the yarn.

[0086] 5. Good formula stability: The gloves of this invention are significantly better than traditional processes under the minimum formula value. The performance of the intermediate and maximum formula values ​​is continuously optimized, indicating that the technical effect of "excellent imitation mink fur texture" can be achieved within the parameter range defined by this invention, and the process compatibility is strong.

[0087] In summary, the faux mink gloves of this invention, through a synergistic design of "selection of reverse-hair yarn + softening modified rubber + targeted combing and shaping + gentle process parameters," significantly outperform traditional gloves in terms of softness, warmth, faux mink fur simulation, and durability. Whether considering the minimum, intermediate, or maximum values ​​of the formula parameters, their overall performance surpasses that of traditional products. The maximum value formula achieves a sensory score of 9.3, with warmth improved by over 65% and durability by over 30%, fully demonstrating the technical advantages and practicality of this invention.
