Description

Technical Field

[0001] The invention belongs to the technical field of textile fabrics, and in particular relates to an imitation mink fabric and a preparation method and application thereof. Background Art

[0002] Faux mink is a type of artificial fur that can be made from different synthetic materials or leathers and is designed to mimic the characteristics of an animal's natural fur, especially mink.

[0003] CN203937266U discloses a mink-like flocking fabric, which includes polyester cloth, water-soluble glue and a fluff layer, the polyester cloth and the fluff layer are bonded with water-soluble glue, the fluff layer includes nylon wool and polyester wool, the nylon wool and the polyester wool are interlaced and distributed, the nylon capillary fineness is 2.5-6D, the nylon wool height is 1.5-6mm, and the thickness of the water-soluble glue is 0.18-0.35mm. The mink-like flocking fabric provided by the technical solution has the characteristics of softness and richness, and has the feel and softness of real mink fabric, but the technical solution is flocked by adhesive, which is not environmentally friendly.

[0004] CN201292474U discloses a mink-like flocking fabric, which includes a base fabric at the bottom layer, an adhesive is applied on the surface of the base fabric, short hairs are bonded to a local position on the adhesive, and then an adhesive is applied to a local position on the short hairs and the base fabric according to pattern requirements, and long hairs are bonded to the adhesive. The mink-like flocking fabric prepared by this technical solution has the natural feel and appearance of mink hair, but this technical solution uses adhesive flocking and is not environmentally friendly.

[0005] CN209813321U discloses a mink-like fabric, which includes a base fabric and fluff, a placement layer is provided on one side of the base fabric, the placement layer is fixedly connected to the base fabric, the base fabric is set to have a structure with a reserved gap inside, the placement layer is provided with placement holes penetrating the placement layer along its thickness direction, one end of the fluff passes through two adjacent placement holes in sequence and both ends are placed outside the placement layer. This technical solution enhances the three-dimensional sense of the mink-like fabric by making the fluff extend out of the placement holes at different lengths, thereby greatly improving the simulation performance and feel of the mink-like fabric, and improving the high-grade nature of the mink-like fabric.

[0006] At present, the preparation of imitation mink fabrics still has the following problems: the production process is too long or the process is complicated, the production cost is high, the production process is not environmentally friendly, and a large amount of harmful substances are produced; the use of adhesive flocking is not environmentally friendly and prone to hair loss; the flocking effect is not good, and it is easy to shed hair during wearing due to low adhesion, which does not meet the requirements of friction fastness.

[0007] Therefore, it is necessary to develop a mink-like fabric which has fluff that is not easy to fall off, feels comfortable, is harmless to human health, and has an environmentally friendly production process. Summary of the invention

[0008] In view of the deficiencies in the prior art, the object of the present invention is to provide an imitation mink fur fabric and a preparation method and application thereof. The preparation method of the imitation mink fur fabric has the characteristics of simple process, safety, environmental protection and low cost. The prepared imitation mink fur fabric is not easy to lose fiber, has no neat mechanical feel, and the fluff feels fluffy and natural.

[0009] In order to achieve the purpose of the invention, the present invention adopts the following technical solutions:

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

[0011] (1) weaving cotton yarn, nylon fiber A and nylon fiber B to prepare a composite fabric having a surface layer and a bottom layer;

[0012] (2) softening the composite fabric obtained in step (1), and performing hair grabbing, combing, and shearing on the bottom layer of the composite fabric to obtain a sheared fabric;

[0013] (3) Drying and shaping the shearling fabric obtained in step (1) to obtain a mink-like fabric.

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

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

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

[0017] In the present invention, the bottom layer of the composite fabric includes nylon fiber B, which is used for hair grabbing to form the fluff in the imitation mink fabric; the surface layer includes cotton yarn, which has a hygroscopic effect and helps to eliminate static electricity. The surface layer and the bottom layer are connected by the cotton yarn and the nylon fiber A. The softening step makes the composite fabric soft and smooth to facilitate hair grabbing, the combing step makes most of the fluff that falls on the composite fabric after hair grabbing stand in order on the surface of the composite fabric, and the shearing makes the fluff form a fixed length to obtain a sheared fabric. By drying, the neat fluff on the sheared fabric is transformed into slightly scattered and fluffy fluff without a neat mechanical feel, more natural, and more fluffy to the touch, forming an imitation mink effect, with natural lodging, soft hand feel and light granulation effect like animal fur. The imitation mink fabric prepared by the preparation method is not easy to lose fiber and has a better lasting effect.

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

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

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

[0021] Preferably, the nylon fiber A comprises 50D34F regenerated nylon 6 semi-bright and stretched Z-twisted yarn.

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

[0023] In the present invention, the regenerated nylon fiber is a commercially available product or is prepared by sorting and crushing waste nylon raw materials (such as waste clothes, socks or ropes, etc.) and then melt-spinning them.

[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 125D96F / 2 regenerated nylon 6 semi-bright elastic Z twist × 2.

[0026] In the present invention, the 125D96F / 2 regenerated nylon 6 semi-bright elastic Z-twist × 2 means that two strands of spun yarn are assembled into one strand to form a 125D96F regenerated nylon 6 semi-bright elastic Z-twist spun yarn, and then two strands of the spun yarn are fed into a yarn nozzle to form a 125D96F / 2 regenerated nylon 6 semi-bright elastic Z-twist × 2.

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

[0028] Preferably, the method further comprises the steps of hair feeding, dyeing, color fixing and yellowing prevention before softening.

[0029] It should be noted that the wool eating, dyeing, color fixing and yellowing prevention treatments described in the present invention all adopt preparation methods known in the art, and are not specifically limited here. The raw materials involved are all conventional commercially available products. The selection of the preparation methods for wool eating, dyeing, color fixing and yellowing prevention treatments will not affect the effects of the present invention. The surface of the composite fabric is treated by wool eating to achieve the effect of improving the surface smoothness and reducing the hair ends, which is better than the effect of singeing; illustratively, the wool eating step can be carried out in a dye vat.

[0030] Preferably, the softening process specifically includes spraying silicone soft oil emulsion on the unfolded composite fabric at the shaping machine head, and after uniform pressing, the fabric enters the shaping machine oven for drying.

[0031] In the present invention, the softening method is to spray a silicone soft oil emulsion on the composite fabric, and after the pressing machine, the fabric is put into the oven of the setting machine for drying, instead of being carried out in the dyeing vat. The reason is that the commonly used silicone soft oil is generally cationic, which will produce precipitation risks with the anionic components in the anti-yellowing agent. The softening step makes the stiff composite fabric soft, which is convenient for subsequent hair grabbing. If the softening is not carried out, it is difficult to grab hair on the composite fabric. The present invention does not have any special restrictions on the type of silicone soft oil in the silicone soft oil emulsion. All commonly used silicone soft oils in the field are applicable, including but not limited to cationic silicone soft oils.

[0032] Preferably, the pressure of the press is 4-6 bar (for example, 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 125-135°C (for example, 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 15-20 m / min (for example, 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 the silicone soft oil in the silicone soft oil emulsion is 50-80 g / L, for example, 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.

[0041] Preferably, the setting value of the covering needle roller of the plucking machine in the hard needle plucking is 1.5-2.5 (for example, 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 needle roller is 5.0-6.0 (for example, 5.1, 5.2, 5.3, 5.4, 5.5, 5.6, 5.7, 5.8 or 5.9, etc.), and the running speed is set to 11-13 m / min (for example, 11.2 m / min, 11.4 m / min, 11.6 m / min, 11.8 m / min, 12 m / min, 12.2m / min, 12.4m / min, 12.6m / min or 12.8m / min, etc.), the drum speed is set to 90-110rpm (for example, 92rpm, 94rpm, 96rpm, 98rpm, 100rpm, 102rpm, 104rpm, 106rpm or 108rpm, etc.), and the tension is set to 1-2N (for example, 1.1N, 1.2N, 1.3N, 1.4N, 1.5N, 1.6N, 1.7N, 1.8N, 1.9N, etc.).

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

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

If the combing conditions are too strong, hair loss or even baldness will occur. If the combing conditions are too weak, the hair is not combed open and the fluffiness is not enough, which will reduce the shearing effect. When the number of combing times is 2 times, the second combing can further comb the hair combed out of the first combing, making it more fluffy and easier to shear, so as to achieve a uniform hair length.

[0047] It should be noted that the setting parameters of the front tension and rear tension of the carding machine are parameters controlled by oil pressure, not the actual tension values.

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

[0049] Preferably, the shearing is performed once.

[0050] Preferably, the shearing machine is a Taiwan Yuantu shearing machine.

[0051] In the present invention, the Taiwan Yuantu wool shearing machine has three main components, a support knife, a flat knife, and a circular wool shearing roller. The Taiwan Yuantu wool shearing machine needs to be zero-calibrated before use.

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

[0053] Preferably, the drying in step (3) is carried out on a drying machine.

[0054] Preferably, the drying 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 (for example, 77°C, 79°C, 81°C, 83°C, 85°C, 87°C or 89°C, etc.), and the time is 8-12 minutes (for example, 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 treatment is 75-85°C (for example, 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 (for example, 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°C (21°C, 22°C, 23°C, 24°C, 25°C, 26°C, 27°C, 28°C or 29°C, etc.), and the time is 8-12 minutes (for example, 8.5 minutes, 9 minutes, 9.5 minutes, 10 minutes, 10.5 minutes, 11 minutes or 11.5 minutes, etc.).

[0058] In the present invention, in the drying step, steam heating causes the nylon fibers in the sheared fabric to expand due to heat; hot air drying allows the sheared fabric to continue to be fluffy after the moisture is completely dried; 20-30°C cold air causes the formed fluff to curl up and slightly granulate, producing a slight shaking effect, breaking the uniform, neat, and mechanical feeling after "grabbing, combing, and shearing", forming a sense of disorder, making the fluff and the granulation effect of the fluff look more natural, and producing a natural feeling similar to mink hair. If the steam temperature processed in the drying machine is too high or the drying speed is too high, the granulation of the fluff will be more obvious, and shearing and degranulation will be required.

[0059] In the present invention, the steam heating treatment can be carried out by unidirectional rotation, and the hot air drying treatment can be carried out by unidirectional rotation or bidirectional rotation. The bidirectional rotation means that the rotating drum in the drying machine rotates forward and reversely, first rotating forward for a period of time, pausing for a few seconds, and then reversing for a period of time, and repeating this process. In the hot air drying treatment, the fluff obtained by unidirectional drying has a directional property, similar to the ironing effect. The positive and negative rotations have a more obvious shaking effect. Those skilled in the art can choose according to actual needs.

[0060] Preferably, the shaping comprises water shaping.

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

[0062] It should be noted that the imitation mink fabric includes a surface layer, a bottom layer and an imitation mink layer disposed on the bottom layer. The thickness of the imitation mink fabric and the length of the fluff in the imitation mink layer are not particularly limited, and those skilled in the art can adjust them according to actual needs. For example, the thickness of the imitation mink fabric is 2 to 3 mm (for example, 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 fluff of the imitation mink fabric is 3 to 6 mm (for example, 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] In a third aspect, the present invention provides a use of the imitation mink 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 the present invention, a composite fabric with a surface layer and a bottom layer is prepared by using cotton yarn, nylon fiber A and nylon fiber B, and the imitation mink fur fabric is prepared through the steps of softening, grabbing the bottom layer of the composite fabric, combing the hair, shearing the hair, throwing it to dry, and shaping it. The imitation mink fur fabric has the advantages of not easy to lose fiber, slightly scattered and fluffy hair, no neat mechanical feeling, fluffy and soft touch, and a natural feeling similar to mink hair, and no need to use adhesive. The preparation method of the imitation mink fur fabric has the advantages of simple process, safety, environmental protection and low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0103] Example 8

[0104] This embodiment provides a mink-like fabric and a preparation method thereof. The difference between this embodiment and embodiment 1 is that the time for cold air cooling at 25° C. in step (3) is adjusted to 5 minutes, and the rest is the same as embodiment 1.

[0105] Comparative Example 1

[0106] This comparative example provides a sheared fabric and a preparation method thereof, which is different from Example 1 only in that step (3) of drying is not included, and the rest is the same as Example 1.

[0107] The imitation mink fabrics provided in Examples 1 to 8 and the shearling fabric provided in Comparative Example 1 were subjected to the following performance tests.

[0108] (1) Appearance: The appearance of the fluff on the bottom layer of the mink-like fabric provided in the example and the shearling fabric provided in the comparative example was observed.

[0109] (2) Fluffy feel: The imitation mink fabrics and shearling fabrics provided in the embodiments and comparative examples were touched to test the fluffiness of the hand feel.

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

[0111] (4) Bottom layer fiber loss resistance test: According to the JIS BQE B 014 hairiness test, the test results are divided into 1 to 5 levels, with 5 being the best. The state between 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, “ / ” means that the test was not conducted.

[0117] The imitation mink fabric provided in Example 1 has a sealing thickness of 140 cm and a gram weight of 550 g / m 2 , Figure 2 This is a surface morphology image of the imitation mink fabric provided in Example 1; Figure 3 A morphology diagram of the imitation mink fur layer of the imitation mink fur fabric provided in Example 1; Figure 4 This is an optical microscope morphology of the imitation mink layer of the imitation mink fabric provided in Example 1. Figure 3 , Figure 4 It can be seen that the imitation mink fabric has slightly scattered and fluffy hair, and has a natural feel similar to mink hair.

[0118] It can be seen from the contents of Table 3 that the imitation mink fur fabric provided in Example 1 is fluffy and soft to the touch, the fluff has no neat mechanical feel, has a natural feel similar to mink fur, and feels dry and non-greasy.

[0119] Compared with Example 1, if the concentration of silicone soft oil in the silicone soft oil emulsion is higher (Example 2), the mink-like fabric prepared is fluffy and soft to the touch, with a natural feel similar to mink hair, but feels greasy. Increasing the silicone soft oil concentration within a certain range will increase the softness of the mink-like fabric, but at the same time, the cohesion between the yarn and the fiber will become loose, which will lead to the deterioration of the anti-pilling test results and anti-snagging performance of the surface layer of the mink-like fabric.

[0120] Compared with Example 1, if the number of hard plucking times is increased (Example 3), the prepared imitation mink fur fabric has better velvet, is fluffy and soft to the touch, has a natural feel similar to mink fur, feels dry and non-greasy, but the explosive force test performance is not as good as Example 1. This is because the mechanical external force strengthens the damage to the yarn, and because of the strengthened damage to the yarn, a certain degree of fiber loss occurs.

[0121] Compared with Example 1, if the machine speed of the second soft needle plucking is too fast (Example 4), the amount of hair picked up by the prepared imitation mink fur fabric is relatively reduced, the density of the fluff is reduced, and it has a natural feel similar to mink fur, feels dry and non-greasy, but the fluffiness when touched is reduced to a certain extent.

[0122] Compared with Example 1, the mink-like fabric prepared in Example 5 has a shorter hot air drying time, from 60 minutes to 30 minutes. A few local parts of the mink-like fabric are not completely dried and then clump together. After the cold air blowing and the subsequent clear water setting process, the fabric effect is not as good as the mink-like fabric prepared in Example 1. A few hairs on the bottom layer do not stand up well, which reduces the fluffiness to a certain extent.

[0123] Compared with Example 1, the feel of the imitation mink fabric prepared in Example 6 is basically the same as that of the imitation mink fabric prepared in Example 1, but the energy consumption in the preparation process is higher, and further enhancing the steam heating conditions in the drying process will not significantly improve the fluffy effect.

[0124] Compared with Example 1, if the steam heating treatment time is too short (Example 7), the prepared imitation mink fur fabric has a poor natural feel similar to mink fur, the yarn is not fully expanded, and the feel is not fluffy enough.

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

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

[0127] The applicant declares that the present invention illustrates the process method of the present invention through the above-mentioned embodiments, but the present invention is not limited to the above-mentioned process steps, that is, it does not mean that the present invention must rely on the above-mentioned process steps to be implemented.
