On the one hand, the shape retention of weft-knitting process is poor, so it is difficult for weft-knitted double-sided pile fabric to meet the needs of the public. On the other hand, most double-sided pile fabrics use chemical fiber as raw material. Therefore, the warmth retention of the fabric is obviously inferior to that of the double-sided pile fabric using cashmere yarn as raw material.

[0004] However, the current cashmere yarn cannot adapt to the damage caused by tension fluctuation during high-speed knitting on warp knitting machine. Although the adjustment of tension rod has improved the situation of excessive tension to some extent, the adjustment of tension rod is mainly based on spring leaf and spring, both of which have certain shortcomings, such as unavoidable vibration of spring leaf and large spring stiffness, which cannot respond in time. Therefore, the adjustment mode of tension rod needs to be further improved. SUMMARY

[0037] In one embodiment of the present application, the warp knitting machine comprises a machine frame, a tension rod and spring sheets, the machine frame and the tension rod are connected through a plurality of triangular spring sheets; one end of the triangular spring sheet is connected with the tension rod, and the other two ends are connected with the machine frame.

[0038] The third object of the present application is to provide a cashmere warp-knitted double-faced pile fabric prepared according to the production method of the cashmere warp-knitted double-faced pile fabric.

[0039] The fourth object of the present application is to provide a garment and home textile product containing the cashmere warp-knitted double-faced pile fabric.

[0040] The beneficial effects of the present application are:

[0041] (1) The conventional double-faced pile fabric is mostly made of chemical fiber, and has poor hand feeling and softness. The present application uses cashmere yarn as raw material, and the cashmere yarn is soft and has good warmth retention. The use of cashmere yarn as raw material can greatly improve the softness and warmth retention of the fabric, and improve the grade of the fabric, thereby meeting the needs of consumers.

[0042] (2) The present application uses cashmere yarn as raw material for knitting. Wool fiber has excellent properties such as natural moisture absorption, air permeability, elasticity and softness, and has a long application history in the field of clothing. In recent years, with the improvement of living standards, changes in market demand and innovation and improvement of production technology, wool products are gradually developing towards light and thin structure, diversified functions, diversified raw materials and diversified styles. Therefore, double-faced pile fabric is gradually valued by consumers. Moreover, the fabric of the present application is prepared by warp knitting, double-needle bed pile fabric is obtained by splitting pile, and single-needle bed pile fabric is obtained by cutting pile. Compared with most weft-knitted double-faced pile fabric, the fabric is not easy to fall apart, has better shape retention, and is more crisp, thereby achieving the purpose of making the fabric more high-grade.

[0043] (3) The fabric of the present application uses a warp knitting machine as a platform, and the knitted fabric has better stability. Moreover, due to the advantages of warp-knitted products, the double-faced pile fabric has better shape retention and improved crispness compared with most existing double-faced pile fabrics.

[0044] (4) The tension rod of the conventional warp knitting machine is composed of a single spring sheet and a spring as the main component. Since the spring sheet is not stable enough and the spring has a slow response, the tension rod cannot achieve good tension adjustment, which makes it difficult for cashmere yarn to adapt to the damage caused by the tension fluctuation of the warp knitting machine during high-speed knitting, and it is difficult to be applied to the warp knitting machine. In order to improve the poor adjustment effect of the tension rod during cashmere warp knitting, the original spring sheet and spring-based tension rod are improved in the present application. The original straight rod type single spring sheet and spring are abandoned, and a triangular structure composed of two spring sheets, a machine frame and a tension rod is used. The stable structure of the triangle can reduce the adjustment error caused by the vibration of the spring sheet itself, thereby achieving the effect of reducing the knitting tension, and further realizing the innovative application of cashmere yarn on the warp knitting machine.

[0045] (5) The conventional warp-knitted fabric is mainly made of chemical filaments. Since the strength of the spun yarn is relatively low, and the cashmere yarn has a high hairiness, it is difficult to be applied to the warp knitting machine. The fabric of the present application uses the warp knitting machine as the platform, and the improved tension rod achieves the effect of reducing the knitting tension, thereby realizing the application of cashmere yarn on the single and double needle bed warp knitting machine. Moreover, by testing the tension curve of the yarn under different tension rods during knitting, it can be seen from the tension fluctuation curve of the yarn during knitting that the spring sheet with a triangular structure has certain advantages, which can reduce the tension fluctuation amplitude and appropriately reduce the tension of the yarn during knitting, thereby providing a basis for the application of spun yarn in the field of warp knitting in the future.

[0046] (6) The production method of the cashmere warp-knitted double-faced pile fabric provided by the present application changes the raw materials and replaces the processing method to make the fabric more comfortable and high-grade. Moreover, in order to realize the selection of various thicknesses and various uses of the fabric, the advantages of different warp knitting machines are fully utilized to carry out knitting on the single and double needle bed warp knitting machines.

[0047] In summary, the present application applies cashmere yarn to warp knitting and reduces the tension while making it more stable through the modification of the tension rod, thereby realizing the new application of cashmere yarn in the field of warp knitting. In addition, the production method of the cashmere warp-knitted double-faced pile fabric provided by the present application designs the cashmere organization with a large needle pitch, thereby realizing the knitting of cashmere yarn on various fabrics.

[0115] The specific parameters of the process of the embodiment are shown in Table 2.

[0116] Table 2

[0117]

[0118]

[0119] In addition, as shown in Figure 3 and 4 , the tension rod of the conventional warp knitting machine is mainly composed of a single spring sheet ( Figure 3 ) and a spring ( Figure 4 ), and due to the instability of the spring sheet itself and the slow response of the spring, the tension rod cannot achieve good tension adjustment, and thus the goat cashmere yarn is difficult to adapt to the damage caused by the tension fluctuation of the warp knitting machine in the high-speed weaving process, and is difficult to be applied to the warp knitting machine.

[0120] In order to improve the poor adjustment effect of the tension rod in the goat cashmere warp knitting process, the original spring sheet and spring-based tension rod are improved.

[0121] As shown in Figure 5As shown, the warp knitting machine provided by the present application comprises a rack 1, a tension rod 2 and spring sheets 3, the rack 1 and the tension rod 2 are connected through a plurality of triangular structure spring sheets 3; one end of the triangular structure spring sheet 3 is connected with the tension rod 2, and the other two ends are both connected with the rack 1. The structure discards the original straight rod type single spring sheet and spring, and instead uses two spring sheets and the rack and the tension rod to form a triangular structure. The stable structure of the triangular structure can weaken the adjustment error caused by the vibration of the spring sheet itself, thereby realizing the effect of reducing the knitting tension, and further realizing the innovative new application of cashmere yarn on the warp knitting machine.

[0122] As Figure 6 shown, Figure 6 is a tension curve diagram of the yarn knitted under the assistance of different tension rods, in which the horizontal coordinate is the rotation angle of the main shaft, and the vertical coordinate is the tension. The present application tests the tension curve of the yarn when knitted under different tension rods, and it can be seen from the tension fluctuation curve of the yarn when knitted that the triangular structure spring sheet has certain advantages, can reduce the tension fluctuation amplitude, and appropriately reduces the tension of the yarn when knitted, thereby providing a basis for the application of staple yarn in the warp knitting field in the future.

[0123] Although the present application has been disclosed as above with reference to the preferred embodiments, it is not intended to limit the present application, and any person skilled in the art can make various modifications and modifications without departing from the spirit and scope of the present application, therefore the protection scope of the present application should be defined by the claims.
