Description

Technical Field

[0001] This invention relates to the field of textile technology, and in particular to a method for preparing a high- and low-hair rabbit fur fabric. Background Technology

[0002] Back printing is a process or technique that involves printing on the back of a fabric. Utilizing a unique visual effect, patterns or textures may appear subtly visible when viewed from the front, adding depth and design to the fabric. Compared to front-printed or solid-color fabrics, it offers a distinctive visual contrast. It's not as flamboyant as front-printed patterns; back-printed designs are relatively understated. However, in certain situations, back printing can be used to add functional markings or information.

[0003] In terms of fabric technology, there are some problems with back-printed fabrics that cannot be ignored.

[0004] 1. During the back printing process, whether through dyeing, heat transfer printing or other methods, the fiber structure of the fabric may be damaged to some extent. This will reduce the strength of the fabric, making it more prone to tearing and damage during use.

[0005] 2. If the dyes used for back printing are of poor quality or the printing process is substandard, color bleeding, fading, and color loss, as well as uneven color between the left, center, and right sides, are likely to occur after washing, rubbing, or prolonged exposure to sunlight.

[0006] 3. Compared to ordinary fabric printing and dyeing, back printing is usually a more complex production process. This requires higher technical skills and more precise equipment. Since printing is more expensive than dyeing, it increases production costs. Moreover, due to the complexity of the process, the scrap rate may be relatively high, and vertical stripes may also occur.

[0007] 4. Because complex processes often mean lower production efficiency, back printing requires more time and effort to complete each step, which may lead to a longer production cycle and make it impossible to meet the needs of large-scale production.

[0008] In the frigid Arctic, there exists a long-standing craft called "Chiengora," which involves collecting dog hair and weaving it into warm clothing. "Chien" means dog in French, and "Gora" is derived from angora wool. This craft relies on collecting shed dog hair from pets, which inherently increases the difficulty of obtaining it, as dog hair is not as readily available on a large scale as traditional animal fibers like wool. Shaving dogs to obtain their hair could cause discomfort or even harm, conflicting with the traditional concept of pet care. Furthermore, in some cultures and cultures, using dog hair in fabric production may raise ethical and moral concerns, with some considering it inappropriate or disrespectful to animals. Finally, the significant differences in texture, length, thickness, and curliness between different dog breeds make it difficult to standardize and maintain consistent quality in dog hair fabrics. Furthermore, dog hair is prone to tangling and knotting. If not handled properly during fabric processing, these knots can affect the fabric's appearance and quality, even creating weak points and compromising its durability. Dog hair collected from dogs requires rigorous washing and disinfection to remove dust, bacteria, grease, and odors. This process is relatively complex and costly; incomplete washing and disinfection can affect the fabric's safety and comfort. Even after processing, dog hair fabrics may still experience some shedding.

[0009] Therefore, by imitating the combination of "Chiengora" and back printing on commercially available fabrics, the purpose of this application is to provide a method for preparing a new type of "high and low hair rabbit fur fabric" that combines the effects of "Chiengora" and back printing. Summary of the Invention

[0010] The purpose of this invention is to provide a method for preparing high- and low-hair rabbit fur fabric, which solves the shortcomings of the two existing fabrics, such as high scrap rate, uneven dyeing, complex processing procedures, long cycle, difficulty in obtaining the fleece, cultural conflicts, and issues related to comfort and environmental protection.

[0011] To achieve the above objectives, the technical solution adopted by the present invention is as follows: This invention provides a method for preparing a high-low wool rabbit fur fabric. The high-low wool rabbit fur fabric includes a base fabric and a pile yarn. The base fabric includes a medium yarn structure and a bottom yarn structure. The bottom yarn structure uses 75D / 144F polyester low elastic yarn (DTY) as the bottom yarn material. The medium yarn structure uses 75D / 36F semi-dull flat polyester filament (FDY) as the medium yarn material. The pile yarn uses two materials: 75D / 72F fully dull flat polyester low elastic yarn (DTY) and 75D / 36F imitation engraving filament (FD) as the pile yarn. Its preparation method includes the following steps: For S1 raw material selection, 75D / 144F polyester low elastic yarn (DTY) is selected as the base yarn material, 75D / 36F semi-dull flat polyester filament (FDY) is selected as the middle yarn material, and 75D / 72F fully dull flat polyester low elastic yarn (DTY) and 75D / 36F imitation engraving filament (FD) are selected as the fleece yarn. S2 warping involves processing the raw materials from S1 using a warping machine. S3 weaving involves feeding the warped raw materials from S2 to the warp knitting machine in a specific ratio. During weaving, the fabric is woven into a raw fabric according to the set needlework process and then split into widths. The needle-feeding process is as follows: GB1: 4330 0114 GB2: 0110 GB3: (0111 0111 0001 0001)*2 GB4: (0001 0001 8999 8999)*2 GB5: :1001 GB6: 1443 3001; S4. Post-processing: The fabric that has been made and split will be processed in sequence as follows: turning, combing, ironing, pre-setting, dyeing (printing), softening, dehydration, drying, napping, combing and shearing, ironing, shaking, and final shaping.

[0012] Furthermore, the insole fabric accounts for 10% to 30% of the mass percentage of the fabric; the plush yarn accounts for 70% to 90% of the mass percentage of the fabric, wherein the ratio of the two raw materials, 75D / 72F fully dull flat polyester low elastic yarn (DTY) and 75D / 36F imitation engraving filament (FD), is 9:7.

[0013] Furthermore, GB1 and GB6 form a base yarn structure, GB2 and GB5 form a middle yarn structure, and GB3 and GB4 form a plush yarn.

[0014] Furthermore, the double needle bed warp knitting machine in S3 is a GE-288-6 type double needle bed warp knitting machine with a machine size of E22 needles / 25.4mm.

[0015] Furthermore, the on-site temperature for warping in S2 is 26±2℃, and the humidity is 60rh~70rh.

[0016] Furthermore, the finishing temperature in the post-processing is 120℃~180℃, and the weaving speed is 53m / min~58m / min.

[0017] Due to the application of the above-mentioned technical solution, the present invention has the following advantages compared with the prior art: The method for preparing high- and low-hair rabbit fur fabric of the present invention achieves the effect of back printing and imitation animal fur by selecting raw materials and processes. The fabric has a non-shedding surface, good standing feel, and a dense and thick bottom. It also makes up for a series of problems caused by back printing and some special techniques of the two fabrics. Attached Figure Description

[0029] This invention provides a method for preparing a high-low wool rabbit fur fabric. The high-low wool rabbit fur fabric includes a base fabric and a pile yarn. The base fabric includes a medium yarn structure and a bottom yarn structure. The bottom yarn structure uses 75D / 144F polyester low-elasticity yarn (DTY) as the bottom yarn material. The medium yarn structure uses 75D / 36F semi-dull flat polyester filament (FDY) as the medium yarn material. The pile yarn uses two materials: 75D / 72F fully dull flat polyester low-elasticity yarn (DTY) and 75D / 36F imitation engraved filament (FD). The base fabric accounts for 20% of the mass percentage of the fabric. The pile yarn accounts for 80% of the mass percentage of the fabric, of which 45% is 75D / 72F fully dull flat polyester low-elasticity yarn (DTY) and 35% is 75D / 36F imitation engraved filament (FD).

[0030] Specifically, the preparation method of high- and low-hair rabbit fur fabric includes the following steps: For S1 raw material selection, 75D / 144F polyester low elastic yarn (DTY) is selected as the base yarn material, 75D / 36F semi-dull flat polyester filament (FDY) is selected as the middle yarn material, and 75D / 72F fully dull flat polyester low elastic yarn (DTY) and 75D / 36F imitation engraving filament (FD) are selected as the fleece yarn. S2 warping involves warping the raw materials from S1 using a warping machine; the on-site temperature for warping is 26±2℃, and the humidity is 60rh~70rh. In S3 weaving, the raw materials after warping in S2 are fed to a double needle bed warp knitting machine according to the proportion. The double needle bed warp knitting machine is a GE-288-6 type double needle bed warp knitting machine with a gauge of E22 needles / 25.4mm. During weaving, the fabric is woven into a greige fabric by manually inputting the warp knitting needle process into the computer control system according to the CRD knitting process and then splitting the fabric. The needlework process is as follows: GB1: 4330 0114 GB2: 0110 GB3: (0111 0111 0001 0001)*2 GB4: (0001 0001 8999 8999)*2 GB5: :1001 GB6: 1443 3001; During weaving, GB1 and GB6 form the base yarn structure, GB2 and GB5 form the middle yarn structure, and GB3 and GB4 form the plush yarn. S4. Post-processing: The fabric, after being made and split, undergoes the following processes in sequence: turning, combing, calendering, pre-setting, dyeing (printing), softening, dehydration, drying, napping, combing and shearing, calendering, pelletizing, and final setting. The final setting temperature is 120℃~180℃, and the fabric speed is 53m / min~58m / min.

[0031] Comparative Example 1 Comparative Example 1 provides a method for preparing high and low hair rabbit fur fabric, which is basically the same as Example 1, except that the GB3 face yarn raw material is 150D / 288F fully matte flat DTY.

[0032] Comparative Example 2 Comparative Example 2 provides a method for preparing high and low hair rabbit fur fabric, which is basically the same as that of Example 1, except that the GB4 face yarn raw material is 150D / 288F glossy flat DTY.

[0033] Comparative Example 3 Comparative Example 3 provides a method for preparing high and low hair rabbit fur fabric, which is basically the same as that of Example 1, except that the GB1 yarn thread stitching process is: 4444 0000 3333 0000.

[0034] Comparative Example 4 Comparative Example 4 provides a method for preparing high and low hair rabbit fur fabric, which is basically the same as Example 1, except that the GB4 yarn process is: 1 thread 1 hole; 0111 011314 13131314.

[0035] To further illustrate the beneficial technical effects of each embodiment, the adhesion, abrasion resistance and shedding (hair adhesion) of the high and low rabbit fur fabrics in Examples 1-5 and Comparative Examples 1-4 were tested. The results of the adhesion, abrasion resistance and shedding tests are listed in Table 1.

[0036]

[0037] As can be seen from Table 1, the high and low wool rabbit fur fabrics processed using the raw materials and processing techniques selected in Example 1, according to the 100-grip test standard, have a best grade of 0. The smaller the color difference value (≤1.5 is difficult to distinguish with the naked eye) and the higher the number of abrasion resistance cycles, the better the back printing effect. In Example 1, referring to... Figure 1 In this example, by selecting the best raw materials for the fleece and coordinating them with the preparation method, the resulting back printing effect is optimal, exhibiting a good imitation of animal fur and providing excellent upright posture; (Reference) Figure 2 According to the shedding test (feather adhesion) test (Japanese standard adhesive method), the high and low hair rabbit fur fabric processed in this example is not easy to shed. In Comparative Example 1, by changing the GB3 yarn material, the fabric produced has a different denier (D) and a different warp feed rate compared to Example 1. This results in a fabric that is prone to yarn breakage and is difficult to work with during weaving. In Comparative Example 2, by changing the raw material of GB4 yarn, the fabric produced at this time, compared with Example 1, does not have the support of special raw material yarn, the fabric produced does not have the back printing effect, and the post-processing shrinkage rate is not high, and it does not have the high and low pile effect. In Comparative Example 3, by changing the stitching process of GB3, the fabric produced at this time has the defect of being prone to shedding at the bottom compared to Example 1. In Comparative Example 4, by changing the stitching process of GB4, the fabric produced at this time has defects such as poor standing feel, insufficient softness, and relatively loose fabric compared to Example 1.

[0038] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
