[0085] The above N is a positive integer, and

[0086] A warp knitting machine includes a machine tool body, a warp knitting traverse device and a transmission mechanism. The warp knitting traverse device is located on the main body of the machine tool, and is connected with the transmission mechanism through a main shaft, turbine reducer and other devices. The transmission mechanism is used for the warp knitting traverse device to control the movement of the yarn guide to generate traverse, so as to knit a corresponding knit structure and form different fabric patterns.

[0087] The warp knitting traverse device includes a face plate, a push rod and a yarn guide bar. A plurality of faceplates is mounted on the main body of the machine tool through shafts, one end of the push rod is in contact with the outer surface of the faceplate, and the other end of the push rod is connected with the yarn guide bar. Due to the different ups and downs on the outer surface of the faceplate, when the faceplate rotates, the push rods that were push against to the faceplate and vice versa will move laterally, thereby driving the yarn guides on the push rods to move laterally, forming the designed knitting process. The faceplate is an integrated structure, and the integrated structure is more conducive to the stability and sustainability of the warp knitting traverse device. Of course, the faceplate is not limited to the above-mentioned integrated structure, and may also be composed of a plurality of chain blocks of different shapes and sizes. The number of the faceplate is generally equal to the number of yarn guides used, at least two (two yarn guides are generally used for a single needle-bed machine to work with two rolls of plush wires).

[0088] In order to better disclose the present application, the solutions of the prior art are introduced below for comparison. FIG. 2 is a schematic diagram of the structure of a faceplate in the four-stroke process. The faceplate is equally divided into 12 sections, and there is only one inclination angle between adjacent sections, and the inclination angle is relatively large. Taking the slope between adjacent sections as an example, there is only one slope in the prior art, and its pressure angle ?1 generally exceeds 40?, while the push movement angle ?1 between adjacent sections is 0-7.5? between. Due to the relatively large inclination angle of the faceplate surface between the four-stroke process sections, when a large displacement is formed, the slope of the faceplate surface is relatively steep and the pressure angle is too large, which will cause a sudden change in acceleration during the movement process. The time duration of displacement is also very limited and insufficient. Long-term use will affect the life of the equipment and affect the good operation of the equipment, and the unstable operation is not conducive to high-speed operation.

[0089] The warp knitting traversing device of the present application, through the improvement of the faceplate, breaks through the limitation that core yarns cannot be arranged in parallel in the same direction in a rectangular area composed of any continuous 2 (sections)?2 (wales) in the traditional process. If the number exceeds 5 or 6, it can solve the problems of insufficient core yarn distribution density, low coverage and low proportion of fabrics produced by traditional processes, especially fabrics with a high square gram weight above 300 g/m.sup.2. details as follows: Warp knitting traversing device, the cross section of the faceplate is an annular shape with unequal outer diameters, and the annular shape is equally divided into x sections along the circumferential direction, where 2?x?8; on the outer surface of the faceplate, at least two slopes are formed between adjacent sections.

[0090] In some embodiments, the range of push movement angle between adjacent sections is 7.5?.sup.?82.5?. The pressure angle of the slope surface ranges from 1 to 39?.

[0091] Specifically, in the case of six strokes, two slope surfaces are formed between adjacent sections, and the pressure angle of any slope surface is in the range of 15 to 35?; in the case of eight strokes, three slope surfaces are formed between adjacent sections, and any slope is formed between two slopes. The pressure angle of the surface ranges from 10 to 15?; for twelve strokes, four slopes are formed between adjacent sections, and the pressure angle of any slope ranges from 5 to 10 degrees; for twenty-four strokes, five or more slopes are formed between the adjacent slopes, and the pressure angle of any slope ranges from 1 to 5?.

[0092] In some embodiments, the transition of the slope surface is arc-shaped, so as to form an overall precise surface curve (arc-shaped surface), so that the movement of the yarn guide is smoother and more precise.

[0093] In some embodiments, the number of yarn guides is i, and 5?i?8.

[0094] In the prior art, due to the large gradient between the sections, the step span is too large, which will damage the machine, and is not conducive to the smoothness of the transverse movement of the yarn guide, thereby affecting the accuracy of the organizational structure; a gradually gentle slope is used for buffering, allowing the yarn guide to move step by step. Through at least two or more steps of transmission, any possible instability caused by the large span can be avoided, which is beneficial to achieving high precision and smoothness in the process of fabric production using the current warp knitting machine, further to reduce fault loss of the machine during continuous production and achieve the high throughput operation.

[0095] The present application will be further described in detail below with reference to specific embodiments. Embodiments 1-3 illustrate the improvement of the faceplate of the present invention. Embodiments 4-7 illustrate the plush fabric of the application, and Embodiments 8-9 illustrate the production process of the plush fabric of the application.

Even if the length of a single section is increased, it will cause an unstable operation, it can still achieve six strokes or eight strokes, and so on, further to be twelve strokes, twenty-four strokes, etc., which can reach at least the displacement of the two-stage transmission yarn guide, which conserves the equipment.

[0189] (4) Slitting of Grey Cloth:

[0190] The double-layer grey fabric knitting in the previous process is slitted through a vertical slitting machine, and the gross height and gram weight of both sides are controlled to be consistent, thereby obtaining a two-sided single-layer grey fabric.

[0191] (5) Processing after dyeing and finishing: [0192] Grey cloth carding: to preliminarily comb the fluff that is tangled together on the cloth surface, and at the same time, it can remove foreign fibers and other impurities on the cloth surface; [0193] Greige fabric ironing: use 160?180? C. quadruple roller ironing to give the cloth surface a certain gloss and flatness; [0194] Greige fabric pre-forming: set the width and overfeeding parameters according to the required door width and gram weight, control the pre-forming temperature at 175-185? C. and the vehicle speed at 20-50M/min, so that the grey fabric can pass through the heating stage, heat balance stage, Preliminary stable size and morphological structure are obtained after the fiber molecular chain rearrangement stage and cooling stage; [0195] Grey cloth dyeing and white grey dyeing (dyed grey cloth does not need to be dyed), using high temperature and high pressure liquid flow dyeing machine, using disperse dyes to dye in the environment of PH6-7, the heating rate is 1.5? C./min, and the temperature is 120?130? C., the holding time is 30-45 min, and the cooling rate is 1.8? C./min; [0196] Softening on the color cloth: using the rolling car, the softening agent and the smoothing agent are mixed with the third-grade water according to the concentration of 30-60 g/L, poured into the rolling groove, and the two-dipping and two-rolling method is adopted, and the speed of the softening is controlled at 5-15M/min, dehydrate the color cloth after softening; [0197] Color cloth drying: Set the temperature of the setting machine to 165-175? C. and the speed of 20-50M/min to remove excess water in the cloth; [0198] Colored wool: 4 sets of brushing machines are used for continuous drawing, and each set of brushing machines is alternately configured with 36 rolls or 36 rolls and 24 rolls, and evenly pulls the plush from the front to the back (except for single-sided plush, which does not need to be brushed); [0199] Colored cloth combing: comb the plush on the front and the plush on the back at least once, comb the plush, and make the front and back sides consistent; [0200] Colored cloth ironing: use two-roller or four-roller ironing at 160?180? C. to further improve the smoothness and gloss of the cloth surface; [0201] Colored cloth shearing: trim the uneven hairs on the cloth surface through the shearing machine, so that the cloth surface hair height is uniform, and the floating hair on the cloth surface is absorbed by the suction device; [0202] Colored cloth shakes: Set the temperature in the shaker cylinder at 60-100? C., so that the cloth plush can form a certain degree of granulation, making the cloth style more refreshing and clear; [0203] Styling of finished colored fabrics: Final shaping is carried out under the condition of 170-180? C., thereby fixing the shape of the fabrics.

[0204] According to the above process, the final fabric is obtained. The finished product has a gram weight of: 380 g/m.sup.2, a wool height of 5 mm, 59% of the veil, and 41% of the core yarn. In the fabric, any continuous 2 (section)?2 (whole section), the number of the core yarns arranged in parallel in the same direction and covering the loops formed by the face yarns is 9 or 10. The fabric is tested by In-House Test Method 019: lint rate 0.11%, transverse washing shrinkage 0.2%, longitudinal tear strength 35.7N, tested by ASTM2149 standard, for Staphylococcus aureus, Escherichia coli, Streptococcus pneumoniae The antibacterial rate can reach more than 96%.

[0205] In the present application, the process in which the knitting needles complete a yarn laying action next time is a section. The distance of the faceplate covered by a yarn-laying action is one stroke.

[0206] The present application innovatively uses the six-stroke or eight-stroke process to produce the warp-knitted double needle-bed plush fabric, which realizes that in the fabric, in the rectangular area formed by any continuous 2 (columns)?2 (wales), there are core yarns in the same direction. The number of N?9 that are arranged in parallel and cover the loops formed by the veil or core yarn breaks through the traditional process because the single maximum traverse movement can only reach 4 or 5 needles and cannot make the core yarn parallel in the same direction The number of distributed arrangement exceeds the limitation of 5 or 6, which solves the problems of insufficient distribution density and low coverage of fabric core yarns produced by traditional processes. In addition, the use of six-stroke or eight-stroke process to replace the traditional four-stroke process to produce warp-knitted double-needle-bed plush fabrics is conducive to the realization of high precision and stability of the warp knitting machine in the process of fabric production, and is conducive to protecting the machine for continuous production. Production is also conducive to realizing the high-speed of the machine and improving the production efficiency by 30% to 50%.

[0207] In this application, a new type of raw material is partially applied to plush products. As the core yarn layer (inner layer) of plush fabrics, on the one hand, it is beneficial to environmental protection. The layer (surface) pile has a higher clamping fastness, which can greatly improve the problem of lint.

[0208] After repeated tests in this application, it is found that when the proportion of the raw material quality of the core yarn layer in the plush fabric is 30-50%, the comprehensive effect is the best, which can greatly improve the hair loss problem without affecting the appearance of the plush fabric. Some feel.

[0209] The fabric of the present application is processed by physical structure innovation instead of chemical method, which can greatly reduce the problem of hair loss, thereby improving the durability and safety of the product during use.

[0210] The fabric part of the present application adopts environmentally friendly or functional raw materials, which can maximize the impact on the style and feel of the fabric while ensuring the embodiment of its environmental protection or functionality, and can solve the problem of raw materials in the post-finishing process. loss, functional degradation, etc.

[0211] The plush fabric produced by the innovative process in this application has a longitudinal tear strength that is about 2 to 3 times that of the traditional process fabric, and can reach 29.4N. In the process of fabric processing and later use, it is not easy to occur due to low tear strength. fabric damage, broken fabrics, etc. In addition, the lateral dimensional stability of the fabric is extremely superior. Under the condition of multiple washings, its lateral shrinkage rate can be maintained at 0-0.4%, which has a significant advantage compared with the lateral shrinkage rate of traditional craft products of 1-3%. Thereby improving the daily performance of the product.

[0212] There are other alternatives, which can also be included in the invention of the present application, but it is not a preferred solution. This alternative has low feasibility and high equipment requirements, and there are few such equipment on the market, which is not suitable for industrial production, and It will also affect the style and feel of existing products.

[0213] Although the present application has been disclosed above with preferred embodiments, it is not intended to limit the present application. Those with ordinary knowledge in the technical field to which this application pertains can make various changes and modifications without departing from the spirit and scope of this application. Therefore, the scope of protection of the present application should be determined by what is defined in the claims.
