Description

Technical Field

[0001] The utility model belongs to the technical field of fabric design, and relates to a mink hair fabric, in particular to a warp-knitted imitation color-discharged water-repellent mink hair fabric. Background Art

[0002] As a common textile material, polyester flannelette is widely popular in the market due to its good warmth retention property and relatively high cost performance. From the initial single-color plain fabric to today's color-woven jacquard products with rich colors and complex patterns, the evolution history of polyester flannelette also reflects the changes in consumer demands and the progress of technology. In recent years, with the improvement of the public's awareness of animal welfare and environmental protection, the requirements for the simulation effect of plush products are also constantly increasing. In order to meet this market demand, the plush industry is actively exploring new chemical fiber filament tip dyeing and printing technologies.

[0003] Although the traditional printing process can achieve a certain decorative effect, due to its complex procedures, it is often accompanied by high color fastness problems and environmental pollution risks. These deficiencies make it increasingly difficult for traditional printing methods to meet the requirements of modern industrial production, especially today when the sustainable development and environmental protection standards are becoming increasingly strict. For example, patent CN100547154C discloses a special discharging process for polyester printed plush fabric, which can achieve different colors at the tips and roots of the hairs to a certain extent, thus making the simulation effect of plush products more vivid. However, although this technology has made progress in improving the simulation degree, it still has some defects, such as complex printing and dyeing processes, difficult industrial wastewater treatment, and unstable color fastness, which limit its application in actual production.

[0004] Facing these challenges, the plush industry needs to continuously explore and research more advanced, environmentally friendly and efficient dyeing and finishing technologies, in order to meet both the consumers' requirements for product quality and design and the environmental protection standards. Simplifying the process flow, reducing environmental pollution, and improving the color fastness of products through technological innovation will be one of the main directions for the future development of the industry. Content of the Utility Model

[0005] The utility model provides a warp-knitted imitation color-discharged water-repellent mink hair fabric to overcome the defects of the prior art.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A warp-knitted imitation color-discharge mink fur fabric, comprising a base layer and a plush layer; the plush layer is composed of a number of plush clusters; each plush cluster is composed of high hairs and low hairs surrounding the high hairs; the roots of the high hairs and the low hairs are both connected within the base layer; the high hairs are super-matte cation-modified polyester full-drawn textured filaments, and the low hairs are super-matte full-drawn textured filaments; and the yarn fineness of the high hairs is coarser than that of the low hairs.

[0008] To optimize the above technical solution, the specific measures taken also include:

[0009] Further, the base layer includes a first weft knitting layer and a second weft knitting layer; the first weft knitting layer is knitted on the outside of the second weft knitting layer; the roots of the high hairs and the low hairs are connected between the first weft knitting layer and the second weft knitting layer.

[0010] Further, the first weft knitting layer has a plain structure, and the second weft knitting layer has a modified plain structure.

[0011] Further, the knitting yarn of the first weft knitting layer is semi-dull full-drawn textured filament, and the knitting yarn of the second weft knitting layer is semi-dull false-twist textured filament.

[0012] Further, the knitting yarn of the first weft knitting layer is 100D / 48F FDY.

[0013] Further, the knitting yarn of the second weft knitting layer is 100D / 96F DTY.

[0014] Further, the knitting yarn of the high hairs is 75D / 8F FDY.

[0016] The beneficial effects of the present utility model are as follows: The present utility model provides a warp-knitted imitation color-discharge mink fur fabric. Through the warp knitting technology, plush clusters composed of low hairs surrounding high hairs are formed on the base layer, realizing the indispensable high-low hair combination in the simulated plush elements and highlighting the hierarchical effect of the plush. At the same time, relatively thick super-matte full-drawn textured filaments are selected as the high hairs, and relatively thin super-matte full-drawn textured filaments are selected as the low hairs, achieving a simulated plush handfeel with both thick and stiff guard hairs and soft and fine underfur through the differences in the single fiber fineness and elongation at break. In addition, super-matte cation-modified polyester full-drawn textured filaments are selected for the high hairs in the plush clusters, while super-matte full-drawn textured filaments are selected for the low hairs. Through dyeing and finishing, the coloring difference between the cationic filaments and the ordinary polyester filaments can be realized, and then the color hierarchy can be achieved, reaching the effect of simulated plush. The present utility model realizes the simulation of mink fur through the fabric structure design and the selection of yarn types, avoiding the disadvantage of poor reproducibility of large goods formed by traditional printing processes, and having excellent simulation effects, energy conservation and environmental protection, etc. Description of the Drawings

[0019] The reference numerals in the figure are: 1, bottom layer; 11, first forming layer; 12, second forming layer; 2, hair layer; 21, hair tufts; 211, long hair; 212, short hair. Specific embodiments

[0020] The following will describe the specific embodiments of the present invention with reference to the accompanying drawings.

[0021] As Figure 1 shown, the present invention provides a warp-knitted imitation color-discharge mink hair fabric, comprising a bottom layer 1 and a hair layer 2.

[0022] The hair layer 2 is composed of a plurality of hair tufts 21.

[0023] As Figure 1 and Figure 2 shown, the hair tuft 21 is composed of long hair 211 and short hair 212. The short hair 212 surrounds the long hair 211 and is lower than the long hair 211. The roots of the long hair 211 and the short hair 212 are both connected within the bottom layer 1.

[0024] Among them, the long hair 211 is a super dull cationic modified polyester full-drawn textured yarn, specifically 75D / 8F FDY; the short hair 212 is a super dull full-drawn textured yarn, specifically 150D / 72F FDY. That is, the long hair 211 is a dyed yarn, and the short hair 212 is an undyed yarn. At the same time, the yarn fineness of the long hair 211 is coarser than that of the short hair 212.

[0025] As Figure 1 shown, the bottom layer 1 includes a first forming layer 11 and a second forming layer 12. The first forming layer 11 is knitted on the outer side of the second forming layer 12 (here, "outer side" refers to the direction facing outward from the overall perspective of the fabric, that is, Figure 1 the lower side of the second forming layer 12 in

[0026] In a preferred embodiment, the first forming layer 11 has a plain warp structure, and the second forming layer 12 has a modified plain warp structure. Both the plain warp structure and the modified plain warp structure are existing knitting structures. The present fabric weaves the first forming layer with the plain warp structure and the second forming layer with the modified plain warp structure together to form the fabric bottom, and the elasticity of this fabric bottom is better, closer to the elasticity of real fur, and the simulation effect is better.

[0027] Among them, the knitting yarn of the first pile layer 11 is semi-dull fully drawn yarn, specifically 100D / 48F FDY; the knitting yarn of the second pile layer 12 is semi-dull false twist textured yarn, specifically 100D / 96F DTY. Through the greater locking force of the textured yarn on the drawn yarn, the consolidation fastness of the fabric plush is improved, achieving the purpose of preventing hair loss.

[0028] The present utility model provides a warp-knitted imitation color-discharge mink fur fabric, which selects two kinds of yarns, high hair and low hair, to be woven into the bottom layer. The low hair surrounds the high hair to form plush clusters, and at the same time, according to the differences in the single fiber fineness and the breaking elongation rate, the plush hand feeling differences between thick, stiff guard hairs and soft, fine underfur are formed, thereby realizing the simulation effect of the mink fur fabric. Since the mink fur fabric of the present utility model mainly realizes the mink fur simulation effect through the structural design of the plush clusters, its production process is shorter, faster, and the production process is more energy-saving and environmentally friendly, so it can replace the current long and complex process of printing first and then discharging white / color-discharge.

[0029] The production process of the warp-knitted imitation color-discharge mink fur fabric of the present utility model is as follows: Use a double-needle bed Raschel plush-type warp knitting machine to weave the grey cloth. After being taken off the machine, it is processed by a HSPM-type plush splitting machine to form 2 pieces of grey plush fabric. Then, through dyeing and setting, wool combing, wool blowing, wool combing, ironing, and setting and rolling, a knitted plush product highly imitating animal real hair is formed. This short-process, high-efficiency, and clean production process conforms to the environmental protection concept. Specifically, regarding the plush layer: During the pulling and knitting process of the middle layer yarn on the warp knitting machine, two groups of yarns, ultra-dull cationic modified polyester fully drawn filaments and ultra-dull fully drawn filaments, are guided to have different yarn path travel distances. After being taken off the machine and split by the splitting machine, a highly simulated effect of high hair and low hair mixed together is presented on a single-piece plush bottom fabric. Regarding the bottom layer: In order to realize the bundling effect on the high hair and low hair, it is necessary to use a warp knitting machine to weave a fabric bottom with sufficient firmness. Specifically, it is realized by each of the two side bottoms using 2 groups (semi-dull fully drawn yarn and semi-dull false twist textured yarn), a total of 4 groups of yarns for knitting.

[0030] In a specific embodiment, the specific parameters of warping and weaving on the machine are shown in Table 1, where the applicable model of the warping machine is DS21 / 40, and the applicable model of the warp knitting machine is GE2886.

[0031] Table 1 Specific parameters of warping and weaving on the machine

[0032]

[0033]

[0034] After being cut by the HSPM plush splitting machine after weaving, a warp-knitted imitation color-discharged mink fur grey fabric is obtained. The grey fabric enters the factory and is pre-set in a setting machine at a temperature of 205 °C and a speed of 40 yards per minute to obtain a to-be-dyed ripe grey fabric. The super-matt cationic modified polyester full-drawn textured yarn is dyed with cationic dyes at 130 °C, while the super-matt full-drawn textured yarn is not dyed, forming a simulation effect of dyed background and printed hair tips. After dyeing and discharging from the vat, it needs to be dried and set twice: at a temperature of 170 °C and a speed of 45 yards per minute to obtain a mink fur dyed grey fabric.

[0035] The above semi-finished colored grey fabric needs to go through the following deep processing and finishing to achieve the final simulation mink fur effect. Specifically as follows: hot air blowing process, temperature 160 °C, speed 2 meters per minute; wool combing process, 5 - 8 yards per minute; ironing process, 5 combined ironing machines, and the process temperature is shown in Table 2.

[0036] Table 2 Specific parameters of ironing:

[0037]

[0038] After finishing all the above processes, it is packed and stored in the warehouse to obtain a warp-knitted imitation color-discharged mink fur fabric.
