Description

Technical Field

[0001] This invention belongs to the field of textile fabric technology, specifically relating to a mink-fur-like fabric, its preparation method, and its application. Background Technology

[0002] Faux mink is a type of artificial fur that can be made from various synthetic materials or leathers and is designed to mimic the natural fur of animals, especially mink.

[0003] CN203937266U discloses a faux mink flocked fabric, comprising polyester fabric, water-soluble adhesive, and a flock layer. The polyester fabric and the flock layer are bonded together with water-soluble adhesive. The flock layer comprises nylon fibers and polyester fibers, which are interspersed. The nylon fibers have a fineness of 2.5–6D and a height of 1.5–6 mm. The thickness of the water-soluble adhesive is 0.18–0.35 mm. This faux mink flocked fabric possesses a soft and supple texture, resembling the feel and softness of genuine mink fabric. However, this method of flocking using adhesives is not environmentally friendly.

[0004] CN201292474U discloses a flocked fabric for imitation mink fur. This flocked fabric includes a base fabric at the bottom, an adhesive coating on the surface of the base fabric, short pile bonded to localized areas of the adhesive, and further adhesive applied to localized areas of the short pile and base fabric according to a pattern, with long pile bonded to the adhesive. The flocked fabric produced by this technology has the natural feel and appearance of mink fur, but this technology uses adhesives for flocking, which is not environmentally friendly.

[0005] CN209813321U discloses a faux mink fabric, comprising a base fabric and a fleece. A mounting layer is provided on one side of the base fabric and is fixedly connected to it. The base fabric has an internally perforated structure. Mounting holes are provided along the thickness direction of the mounting layer. One end of the fleece passes through two adjacent mounting holes sequentially, with both ends positioned outside the mounting layer. This technical solution enhances the three-dimensionality of the faux mink fabric by varying the length of the fleece extending beyond the mounting holes, thereby significantly improving its simulation performance and feel, and enhancing its premium quality.

[0006] Currently, the preparation of imitation mink fur fabric still faces the following problems: the production process is too long or complex, resulting in high production costs; the production process is not environmentally friendly and generates a large amount of harmful substances; the use of adhesives for flocking is not environmentally friendly and easily leads to shedding; the flocking effect is poor, and the fabric is prone to shedding during wear due to low adhesion, failing to meet the requirements for friction fastness.

[0007] Therefore, there is a need to develop a faux mink fabric that is not prone to shedding, has a comfortable feel, is harmless to health, and is environmentally friendly in its production process. Summary of the Invention

[0008] To address the shortcomings of existing technologies, the present invention aims to provide a faux mink fur fabric, its preparation method, and its application. The preparation method of the faux mink fur fabric is characterized by its simple process, safety, environmental friendliness, and low cost. The resulting faux mink fur fabric is not prone to fiber shedding, has no neat mechanical feel, and has a fluffy and natural feel.

[0009] To achieve this objective, the present invention adopts the following technical solution:

[0010] In a first aspect, the present invention provides a method for preparing imitation mink fur fabric, the method comprising the following steps:

[0011] (1) Cotton yarn, nylon fiber A and nylon fiber B are woven into a composite fabric with a top layer and a bottom layer.

[0012] (2) Soften the composite fabric obtained in step (1), and scrape, comb and shear the bottom layer of the composite fabric to obtain sheared fabric.

[0013] (3) The sheared fabric obtained in step (1) is dried and shaped to obtain imitation mink fabric.

[0014] Preferably, the weaving is performed on a double-sided circular knitting machine.

[0015] Preferably, the surface layer comprises cotton yarn.

[0016] Preferably, the bottom layer comprises nylon fiber B.

[0017] In this invention, the bottom layer of the composite fabric includes nylon fiber B, which is used for brushing to form the pile of the faux mink fabric. The top layer includes cotton yarn, which absorbs moisture and helps eliminate static electricity. The top and bottom layers are connected by needles connecting the cotton yarn and nylon fiber A. The softening step makes the composite fabric soft and pliable for brushing, the combing step makes most of the pile that was lying flat on the composite fabric after brushing stand up in an orderly manner on the surface of the composite fabric, and the shearing step makes the pile form a fixed length, resulting in a sheared fabric. By tumble drying, the neat pile on the sheared fabric is transformed into a slightly messy, fluffy pile, without the neat mechanical feel, more natural, and with a fluffier touch, forming a faux mink effect, with the natural lying, soft hand feel, and light granulation effect of animal fur. The faux mink fabric prepared by this method is less prone to fiber shedding and has a better durability.

[0018] Preferably, the fineness of the cotton yarn is 10 to 100S, such as 20S, 30S, 40S, 50S, 60S, 70S, 80S or 90S.

[0019] Preferably, the nylon fiber A comprises recycled nylon fiber.

[0020] Preferably, the fineness of the nylon fiber A is 6 to 125D, such as 20D, 40D, 60D, 80D, 100D or 120D.

[0021] Preferably, the nylon fiber A comprises 50D34F recycled nylon 6 semi-dull textured yarn with Z-twist.

[0022] Preferably, the nylon fiber B comprises recycled nylon fiber.

[0023] In this invention, the recycled nylon fiber is a commercially available product or is prepared by sorting, crushing and then melting and spinning waste nylon raw materials (such as waste clothes, socks or ropes).

[0024] Preferably, the fineness of the nylon fiber B is 12-250D, such as 40D, 80D, 120D, 160D, 200D or 240D.

[0025] Preferably, the nylon fiber B comprises 2 x 125D96F / 2 recycled nylon 6 semi-glossy textured Z-twist.

[0026] In this invention, the 125D96F / 2 recycled nylon 6 semi-dull textured Z-twist yarn means that two strands of yarn are combined into one strand to form a 125D96F recycled nylon 6 semi-dull textured Z-twist yarn, and then the two strands of this yarn are fed into a yarn feeder to form 125D96F / 2 recycled nylon 6 semi-dull textured Z-twist yarn.

[0027] Preferably, the composite fabric comprises the following components by weight percentage: 25%–35% cotton yarn (e.g., 26%, 27%, 28%, 29%, 30%, 31%, 32%, 33%, or 34%), 5%–15% nylon fiber A (e.g., 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, or 14%), and 60%–75% nylon fiber B (e.g., 62%, 64%, 66%, 68%, 70%, 72%, or 74%).

[0028] Preferably, the process before softening further includes steps of hair feeding, dyeing, color fixing, and anti-yellowing treatment.

[0029] It should be noted that the preparation methods for wool feeding, dyeing, color fixing, and anti-yellowing treatments described in this invention are all known in the art and are not specifically limited here. The raw materials involved are all conventional commercially available products. The choice of preparation methods for wool feeding, dyeing, color fixing, and anti-yellowing treatments will not affect the effect of this invention. Treating the surface of the composite fabric with wool feeding to improve surface smoothness and reduce lint is more effective than singeing. The wool feeding step can be carried out in a dyeing vat, for example.

[0030] Preferably, the softening process includes spraying a silicone softening oil emulsion onto the unfolded composite fabric at the setting head, and after being pressed evenly, entering the drying oven of the setting machine for drying.

[0031] In this invention, the softening process involves spraying a silicone softening oil emulsion onto the composite fabric, followed by pressing and drying in the oven of a setting machine, rather than performing the process in a dyeing vat. This is because commonly used silicone softeners are generally cationic, which could potentially cause precipitation with the anionic components in anti-yellowing agents. The softening step softens the stiff composite fabric, making it easier to gather and lift the fibers later. Without softening, it is difficult to gather and lift the fibers from the composite fabric. This invention does not impose any special limitations on the type of silicone softener in the silicone softening oil emulsion; commonly used silicone softeners in the art are applicable, including but not limited to cationic silicone softeners.

[0032] Preferably, the pressure of the press is 4 to 6 bar (e.g., 4.2 bar, 4.4 bar, 4.6 bar, 4.8 bar, 5.0 bar, 5.2 bar, 5.4 bar, 5.6 bar, or 5.8 bar, etc.), the temperature of the oven is 125 to 135°C (e.g., 126°C, 127°C, 128°C, 129°C, 130°C, 131°C, 132°C, 133°C, or 134°C, etc.), and the speed of the setting machine is 15 to 20 m / min (e.g., 15.5 m / min, 16 m / min, 16.5 m / min, 17 m / min, 17.5 m / min, 18 m / min, 18.5 m / min, 19 m / min, or 19.5 m / min, etc.).

[0033] Preferably, the concentration of silicone oil in the silicone oil emulsion is 50-80 g / L, such as 53 g / L, 56 g / L, 59 g / L, 62 g / L, 65 g / L, 68 g / L, 71 g / L, 73 g / L, 76 g / L or 79 g / L, and more preferably 50-60 g / L.

[0035] Preferably, the hair-removing machine is an Italian Lafer hair-removing machine.

[0036] Preferably, the hair-grabbing specifically includes sequential soft-needle hair-grabbing and hard-needle hair-grabbing.

[0037] In this invention, "hard needle brushing" refers to brushing hair using the hard needle roller of a lafer brushing machine, and "soft needle brushing" refers to brushing hair using the soft needle roller of a lafer brushing machine.

[0038] Preferably, the soft needle performs the hair-grabbing action twice.

[0039] Preferably, the number of times the hard needle scratches the hair is 3.

[0040] Preferably, in the soft needle hair-grabbing machine, the setting value of the covering roller is 4.5-5.5 (e.g., 4.6, 4.7, 4.8, 4.9, 5.0, 5.1, 5.2, 5.3, or 5.4, etc.), the setting value of the starting roller is 4.0-5.0 (e.g., 4.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.7, 4.8, or 4.9, etc.), and the machine speed is set to 14-16 m / min (e.g., 14.2 m / min, 14.4 m / min, 14.6 m / min, 14.8 m / min, 15 m / min). The speeds are 0 m / min, 15.2 m / min, 15.4 m / min, 15.6 m / min, or 15.8 m / min, etc., and the drum speed is set to 90-110 rpm (e.g., 92 rpm, 94 rpm, 96 rpm, 98 rpm, 100 rpm, 102 rpm, 104 rpm, 106 rpm, or 108 rpm, etc.). The tension is set to 5-6 N (e.g., 5.1 N, 5.2 N, 5.3 N, 5.4 N, 5.5 N, 5.6 N, 5.7 N, 5.8 N, or 5.9 N, etc.).

[0041] Preferably, in the hard needle hair-grabbing machine, the setting value of the covering roller is 1.5–2.5 (e.g., 1.6, 1.7, 1.8, 1.9, 2.0, 2.1, 2.2, 2.3, or 2.4, etc.), the setting value of the starting roller is 5.0–6.0 (e.g., 5.1, 5.2, 5.3, 5.4, 5.5, 5.6, 5.7, 5.8, or 5.9, etc.), and the machine speed is set to 11–13 m / min (e.g., 11.2 m / min, 11.4 m / min, 11.6 m / min, 11.8 m / min, 12 m / min, etc.). The drum speed is set to 90-110 rpm (e.g., 92 rpm, 94 rpm, 96 rpm, 98 rpm, 100 rpm, 102 rpm, 104 rpm, 106 rpm, or 108 rpm), and the tension is set to 1-2 N (e.g., 1.1 N, 1.2 N, 1.3 N, 1.4 N, 1.5 N, 1.6 N, 1.7 N, 1.8 N, 1.9 N).

[0042] Preferably, the combing is performed on a combing machine.

[0043] Preferably, the combing is performed 1 to 2 times.

[0044] Preferably, the combing machine is a combing machine manufactured by Keywheel Machinery Co., Ltd. in Taiwan, China.

[0045] Preferably, the front tension setting parameter of the combing machine is 90-105 (e.g., 92, 94, 96, 98, 100, 102 or 104, etc.), the rear tension setting parameter is 90-105 (e.g., 92, 94, 96, 98, 100, 102 or 104, etc.), the starting roller setting parameter is 25-35 (e.g., 26, 27, 28, 29, 30, 31, 32, 33 or 34, etc.), the covering roller setting parameter is 5-15 (e.g., 6, 7, 8, 9, 10, 11, 12, 13 or 14, etc.), and the machine speed is 10-20 m / min (e.g., 11 m / min, 12 m / min, 13 m / min, 14 m / min, 15 m / min, 16 m / min, 17 m / min, 18 m / min or 19 m / min, etc.).

[0046] The preferred parameters for the front tension and rear tension of the combing machine described in this invention are 90-105, 25-35 for the starting roller, 5-15 for the covering roller, and 10-20 m / min for the machine speed. If the combing conditions are too strong, hair loss or even bald patches may occur; if the combing conditions are too weak, the hair will not be properly combed and will lack fluffiness, thus compromising the shearing effect. When the combing is performed twice, the second combing further opens up the hair from the first combing, making it fluffier and easier to shear, achieving a uniform hair length and a neat finish.

[0047] It should be noted that the front and back tension settings of the combing machine are hydraulic control parameters, not actual tension values.

[0048] Preferably, the shearing is performed on a shearing machine.

[0049] Preferably, the hair is sheared once.

[0050] Preferably, the shearing machine is a Yuan Tu shearing machine from Taiwan, China.

[0051] In this invention, the Taiwan Yuantu shearing machine has three main components: a support blade, a flat blade, and a circular shearing roller. The Taiwan Yuantu shearing machine must be zero-position calibrated before use.

[0052] Preferably, the shearing blade of the shearing machine rotates at a speed of 900–1100 r / min (e.g., 920 r / min, 940 r / min, 960 r / min, 980 r / min, 1000 r / min, 1020 r / min, 1040 r / min, 1060 r / min, or 1080 r / min, etc.), the blade spacing is set to 450–470 (e.g., 452, 454, 456, 458, 460, 462, 464, 466, or 468, etc.), and the blade holder is set to 190–210 (e.g., 192, 19...). 4. 196, 198, 200, 202, 204, 206 or 208, etc.), with a machine speed of 15-25 m / min (e.g. 16 m / min, 17 m / min, 18 m / min, 19 m / min, 20 m / min, 21 m / min, 22 m / min, 23 m / min or 24 m / min, etc.), and a tension setting of 0.4-0.6 N (e.g. 0.42 N, 0.44 N, 0.46 N, 0.48 N, 0.50 N, 0.52 N, 0.54 N, 0.56 N or 0.58 N, etc.).

[0053] Preferably, the scorching in step (3) is performed on a scorching machine.

[0054] Preferably, the drying process in step (3) specifically includes steam heating treatment, hot air drying treatment, and cold air cooling.

[0055] Preferably, the temperature of the steam heating treatment is 75-90°C (e.g., 77°C, 79°C, 81°C, 83°C, 85°C, 87°C, or 89°C, etc.), and the time is 8-12 minutes (e.g., 8.5 minutes, 9 minutes, 9.5 minutes, 10 minutes, 10.5 minutes, 11 minutes, or 11.5 minutes, etc.).

[0056] Preferably, the temperature of the hot air drying process is 75-85°C (e.g., 76°C, 77°C, 78°C, 79°C, 80°C, 81°C, 82°C, 83°C, or 84°C, etc.), and the time is 50-70 minutes (e.g., 45 minutes, 50 minutes, 55 minutes, 60 minutes, 65 minutes, 70 minutes, or 75 minutes, etc.).

[0057] Preferably, the temperature of the cold air cooling is 20-30℃ (21℃, 22℃, 23℃, 24℃, 25℃, 26℃, 27℃, 28℃ or 29℃, etc.), and the time is 8-12 minutes (e.g. 8.5 minutes, 9 minutes, 9.5 minutes, 10 minutes, 10.5 minutes, 11 minutes or 11.5 minutes, etc.).

[0058] In this invention, during the tumble drying step, steam heating causes the nylon fibers in the sheared fabric to expand; hot air drying allows the fabric to remain fluffy after the moisture has evaporated; and cold air at 20-30°C causes the formed pile to curl and slightly clump, creating a slight clumping effect. This breaks the uniformity, neatness, and mechanical feel of the "grabbing, combing, and shearing" process, creating a disordered feel and making the pile and its clumping effect look more natural, producing a natural feel similar to mink fur. If the steam temperature in the tumble dryer is too high or the tumble drying speed is too high, the pile clumping will be more obvious, requiring further shearing and de-clumping.

[0059] In this invention, unidirectional rotation can be used in the steam heating treatment, and unidirectional or bidirectional rotation can be used in the hot air drying treatment. Bidirectional rotation refers to the forward and reverse rotation of the rotating drum in the blast dryer; it rotates forward for a period of time, pauses for a few seconds, then reverses for a period of time, and repeats this process. In the hot air drying treatment, the fluff produced by unidirectional blast drying has a directional quality, similar to a styling effect. Using both forward and reverse rotation results in a more pronounced granulation effect. Those skilled in the art can choose the appropriate method based on actual needs.

[0060] Preferably, the shaping process includes water-based shaping.

[0061] In a second aspect, the present invention provides a faux mink fur fabric, which is prepared by the preparation method described in the first aspect.

[0062] It should be noted that the faux mink fabric includes a top layer, a bottom layer, and a faux mink fur layer disposed on the bottom layer. The thickness of the faux mink fabric and the length of the down in the faux mink fur layer are not specifically limited, and those skilled in the art can adjust them according to actual needs. For example, the thickness of the faux mink fabric is 2–3 mm (e.g., 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, or 2.9 mm); the length of the down in the faux mink fabric is 3–6 mm (e.g., 3.3 mm, 3.6 mm, 3.9 mm, 4.2 mm, 4.5 mm, 4.8 mm, 5.1 mm, 5.4 mm, or 5.7 mm, etc.).

[0063] Thirdly, the present invention provides an application of the faux mink fur fabric as described in the second aspect in clothing.

[0064] Compared with the prior art, the present invention has the following beneficial effects:

[0065] In this invention, a composite fabric with a top layer and a bottom layer is made using cotton yarn, nylon fiber A, and nylon fiber B. The composite fabric is then softened, and the bottom layer is brushed, combed, sheared, and dried before being shaped to obtain a faux mink fabric. This faux mink fabric is characterized by its resistance to fiber shedding, a slightly messy and fluffy texture, lack of a neat, mechanical feel, a soft and fluffy touch, and a natural feel similar to mink fur. It also eliminates the need for adhesives. The preparation method of this faux mink fabric is simple, safe, environmentally friendly, and low-cost. Attached Figure Description

[0071] The technical solution of the present invention will be further illustrated below through specific embodiments. Those skilled in the art should understand that the embodiments described are merely illustrative of the invention and should not be considered as specific limitations thereof. The processes for hair feeding, dyeing, color fixing, and anti-yellowing treatment in the following embodiments and comparative examples are the same; the cationic silicone oil used in the softening step is a commercially available product, and the same commercially available product was used in parallel experiments.

[0072] Example 1

[0073] This embodiment provides a faux mink fur fabric and its preparation method, such as... Figure 1 As shown, the faux mink fabric includes a top layer 1, a bottom layer 2, and a faux mink fur layer 3 disposed on the bottom layer.

[0074] The preparation method of the faux mink fur fabric is as follows:

[0075] (1) A composite fabric with a top layer and a bottom layer is made by knitting cotton yarn, nylon fiber A and nylon fiber B on a double-sided circular knitting machine; the top layer includes cotton yarn, the bottom layer includes nylon fiber A and nylon fiber B, and the top layer and the bottom layer are connected by needles of cotton yarn and nylon fiber A.

[0076] The composite fabric comprises the following components by weight percentage: 27% cotton yarn, 7% nylon fiber A, and 66% nylon fiber B.

[0077] The cotton yarn is 40S1 COMPACT COTTON dark-colored yarn.

[0078] The nylon fiber A is 50D34F recycled nylon 6 semi-dull textured yarn with Z-twist.

[0079] The nylon fiber B is 125D96F / 2 recycled nylon 6 semi-dull textured yarn with Z twist × 2.

[0080] (2) The composite fabric obtained in step (1) is subjected to hair feeding, dyeing, color fixing and anti-yellowing treatment, then softening, and then the bottom layer of the composite fabric is scraped, combed and sheared to obtain sheared fabric.

[0081] The aforementioned softening process specifically includes spraying a silicone softening oil emulsion (composed of cationic silicone softening oil and water, with a cationic silicone softening oil concentration of 50 g / L) onto the composite fabric using an automatic spraying machine at the stenter head. This process thoroughly saturates the composite fabric in a short time. After being pressed, the fabric enters the oven of the stenter for drying. The reference pressure of the press is 5 bar, the reference temperature of the oven is 130°C, and the reference speed of the stenter is 17 m / min. The goal is to ensure that the fabric surface is completely dry upon exiting the machine.

[0082] The above-mentioned hair removal specifically includes two soft-needle hair removals using one Italian Lafer hair removal machine and three hard-needle hair removals using one Italian Lafer hair removal machine. The parameter settings for the five hair removals are shown in Table 1 below.

[0083] Table 1

[0084]

[0085] The combing process specifically involves two combing operations using a combing machine manufactured by Keywheel Machinery Co., Ltd. in Taiwan, China. During the first and second combing operations, the front tension of the combing machine is set to 98, the rear tension is set to 95, the starting roller parameter is set to 30, the covering roller parameter is set to 11, and the machine speed is 15m / min.

[0086] The shearing specifically includes one shearing using a Taiwan Yuantu shearing machine. The shearing machine has a blade rotation speed of 1000 r / min, a blade distance of 460, a blade holder of 200, a machine speed of 20 m / min, and a tension of 0.5 N.

[0087] (3) The sheared wool fabric obtained in step (2) is placed in a blast dryer for blast drying. Blanching includes three steps: steam heating, hot air drying, and cold air cooling. Steam heating is specifically performed by rotating in one direction for 10 minutes under steam heating treatment at 80°C, with the rotation speed set at 20 r / min. Hot air drying is specifically performed by rotating in both directions for 60 minutes under hot air drying treatment at 80°C. The bidirectional rotation is performed according to the factory default settings of the blast dryer, with a rotation speed of 30 r / min. In each forward and reverse rotation cycle, the forward rotation time is 25 s, the forward and reverse rotation transition time is 3 s, the stop time is 5 s, and the reverse rotation time is 25 s. Cold air cooling is specifically performed by rotating in one direction for 10 minutes under cold air cooling at 25°C, with the rotation speed set at 20 r / min. After blast drying, the fabric is passed through a setting machine. The head slurry tank is rinsed with clean water, and after being uniformly pressed, it enters the oven of the setting machine for drying and setting to obtain the imitation mink fur fabric.

[0106] This comparative example provides a sheared fabric and its preparation method. The only difference between this example and Example 1 is that it does not include the drying process in step (3). Otherwise, it is the same as Example 1.

[0107] The following performance tests were conducted on the imitation mink fabrics provided in Examples 1-8 and the sheared fabric provided in Comparative Example 1.

[0108] (1) Appearance: Observe the appearance of the down on the bottom layer of the imitation mink fabric provided in the embodiment and the sheared fabric provided in the comparative example.

[0109] (2) Fluffiness: The fluffiness of the faux mink and sheared fabrics provided in the examples and comparative examples was tested by touching them.

[0110] (3) Bursting force test: The test shall be conducted in accordance with GB / T 19976-2005 "Determination of bursting strength of textiles by steel ball method".

[0111] (4) Bottom layer fiber shedding test: According to JIS BQE B 014 lint adhesion test, the test results are divided into 1 to 5 levels, with level 5 being the best. The state between the two integer levels is represented by a decimal.

[0112] The test results are shown in Table 3 below.

[0113] Table 3

[0114]

[0115]

[0116] In Table 3, " / " indicates that the test was not performed.

[0117] The faux mink fabric provided in Example 1 has a width of 140 cm and a weight of 550 g / m². 2 , Figure 2 A surface morphology diagram of the faux mink fur fabric provided in Example 1; Figure 3 This is a morphological diagram of the imitation mink fur layer of the imitation mink fur fabric provided in Example 1; Figure 4 This is an optical microscope image of the faux mink fur layer of the faux mink fabric provided in Example 1. Figure 3 , Figure 4 It is known that faux mink fabric has slightly messy, fluffy fur, which has a natural feel similar to mink fur.

[0118] As shown in Table 3, the faux mink fabric provided in Example 1 has a fluffy and soft feel, with no neat mechanical feel in the pile, but a natural feel similar to mink fur, and a dry and non-greasy feel.

[0119] Compared to Example 1, if the concentration of silicone oil in the silicone oil emulsion is higher (Example 2), the resulting faux mink fabric has a fluffy and soft feel, similar to the natural texture of mink fur, but it also feels oilier. Increasing the concentration of silicone oil within a certain range will improve the softness of the faux mink fabric, but at the same time, it will loosen the cohesion between yarns and fibers, leading to poorer pilling resistance and anti-snagging performance of the faux mink fabric.

[0120] Compared with Example 1, if the number of hard scratches is increased (Example 3), the resulting imitation mink fabric has better pile, a fluffy and soft feel, a natural feel similar to mink fur, and a dry and non-greasy hand feel. However, its bursting force test performance is not as good as that of Example 1. This is because the mechanical external force strengthens the damage to the yarn, and because of the strengthened damage to the yarn, there is a certain degree of fiber shedding.

[0121] Compared with Example 1, if the speed of the machine for the two soft needle hair-grabbing processes is too fast (Example 4), the amount of hair picked up by the prepared imitation mink fur fabric will be relatively reduced, the density of the down will be reduced, and it will have a natural feel similar to mink fur. It will feel dry and non-greasy to the touch, but the fluffiness when touched will be reduced to a certain extent.

[0122] Compared with Example 1, the imitation mink fabric prepared in Example 5 had a less than ideal surface finish because the hot air drying time was reduced from 60 minutes to 30 minutes. This resulted in some areas of the fabric not drying completely and clumping together. After further processing with cold air and water finishing, the fabric surface finish was not as good as that of the imitation mink fabric prepared in Example 1. Some of the downy fibers on the bottom layer did not stand up well, which reduced the fluffiness to a certain extent.

[0123] Compared with Example 1, the faux mink fabric prepared in Example 6 has a similar feel to the faux mink fabric prepared in Example 1, but the preparation process consumes more energy. Further strengthening the steam heating conditions in the drying process will not significantly improve the fluffiness.

[0124] Compared with Example 1, if the steam heating treatment time is too short (Example 7), the resulting imitation mink fur fabric has a poorer natural feel similar to mink fur, the yarn does not expand sufficiently, and the hand feel is not fluffy enough.

[0125] Compared with Example 1, if the cooling time of 25°C cold air is too short (Example 8), the resulting imitation mink fur fabric has a poorer granulation effect, lacks the natural feel of slight granulation, and has a poorer natural feel similar to mink fur.

[0126] Compared with Example 1, if the drying process in step (3) (Comparative Example 1) is not included, the prepared sheared fabric has uniform and neat pile, strong mechanical feel, and the bottom layer is not fluffy and soft enough, and does not have a natural feel similar to mink fur.

[0127] The applicant declares that the present invention is illustrated by the above embodiments, but the present invention is not limited to the above process steps, that is, it does not mean that the present invention must rely on the above process steps to be implemented. Those skilled in the art should understand that any improvements to the present invention, equivalent substitutions of the raw materials used in the present invention, addition of auxiliary components, selection of specific methods, etc., all fall within the protection scope and disclosure scope of the present invention.
