Description

Technical Field

[0001] The invention relates to the technical field of textile weaving, in particular to a method for manufacturing a double jacquard warp knitted fabric of a composite structure. Background Art

[0002] Shoes, bags, and decorative products are mainly made of woven fabrics. Although woven fabrics have high physical properties, are durable, sun-resistant, and not easily deformed, they have very large pattern limitations and low elasticity, which seriously affect their appearance and comfort. The market has gradually recognized knitted products with better comprehensive performance. In order to meet the requirements of comfort, they are not hesitant to sacrifice the requirements of high physical properties, resulting in a significant reduction in the durability and appearance retention of the products.

[0003] In the market, weft knitted products were very popular for a period of time, especially after the application of weft knitting's one-piece molding technology and flying wire technology, which greatly improved the practicality and aesthetics. However, due to their excessive elasticity, weft knitted products often need to be compounded with other materials to increase physical properties in order to be better used.

[0004] The products produced by the lace machines in the prior art can only produce some specific products due to the limitation of physical properties. Most of the products need to be compounded again to overcome the limitation of their physical properties, but the problem of lack of three-dimensional pattern surface and high physical properties has not been solved. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide a production method that can solve the problem of double jacquard warp knitted fabrics on the market lacking three-dimensional pattern surfaces and requiring subsequent composite materials for reinforcement and embroidery post-processing.

[0006] The present invention is implemented by the following method: a method for manufacturing a double jacquard warp knitted fabric of a composite structure, the manufacturing method comprising the following steps:

[0007] Step S1, the machine selects PB1-PBN, JB(N+1).1, JB(N+1).2, JB(N+2).1, JB(N+2).2, F, GB(N+3), GB(N+4), GB(N+5);

[0009] Step S3, inlay needle movement mode: PB1-PBN, JB(N+1).1, JB(N+1).2, JB(N+2).1, JB(N+2).2 all adopt open loop forming process or closed loop forming process; GB(N+3), GB(N+4) adopt loop forming process; GB(N+5)

[0010] Adopt weft inserting technology;

[0011] Step S4, yarn selection: the front yarn uses highly wear-resistant yarn, and the back yarn uses soft skin-friendly yarn;

[0013] Furthermore, the step S1 is further specified as follows: PBN is selectively configured on the pattern.

[0014] Furthermore, the step S3 is further specified as follows: the loop forming process includes open loop forming and closed loop forming, the basic yarn inlay structure GB (N+5) is an optional comb, and is used in a weft insertion manner.

[0015] Furthermore, the step S4 is further specified as follows: different raw materials are used in the selection of yarns according to the characteristics of the pattern, the front yarn is made of highly wear-resistant yarn, and the back yarn is made of soft and skin-friendly yarn. Different types of yarns for the back and front can highlight the two-color effect.

[0016] Furthermore, the step S5 is further specified as follows: the warp let-off amount of GB(N+3) and GB(N+4) is 600-3000 mm / ng, the warp let-off amount of JB(N+1).1, JB(N+1).2, JB(N+2).1, and JB(N+2).2 is 240-1500 mm / ng, and GB(N+5) is an optional comb, and the warp let-off amount when used is 130-800 mm / ng.

[0017] The beneficial effects of the present invention are as follows: the present invention can solve the problem that the double jacquard warp knitted fabrics produced on the market lack a three-dimensional pattern surface and the product demand for subsequent processing such as composite reinforcement and embroidery with other materials; it is mainly used in shoes, bags, and decorative products, and the products require high physical properties, high wear resistance, beautiful and exquisite appearance, and also have the characteristics of being able to be formed in one time, saving a lot of post-processing workload, and having the characteristics of environmental protection, good skin affinity, durability, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] See also Figure 1 As shown, the present invention provides an embodiment: a method for manufacturing a double jacquard warp knitted fabric of a composite structure, the manufacturing method comprising the following steps:

[0022] Step S1, the machine selects PB1-PBN, JB(N+1).1, JB(N+1).2, JB(N+2).1, JB(N+2).2, F, GB(N+3), GB(N+4), GB(N+5);

[0024] Step S3, inlay needle movement mode: PB1-PBN, JB(N+1).1, JB(N+1).2, JB(N+2).1, JB(N+2).2 all adopt open loop forming process or closed loop forming process; GB(N+3), GB(N+4) adopt loop forming process; GB(N+5)

[0025] Adopt weft inserting technology;

[0026] Step S4, yarn selection: the front yarn uses highly wear-resistant yarn, and the back yarn uses soft skin-friendly yarn;

[0027] Step S5, machine parameters: PB1-PBN, JB(N+1).1, JB(N+1).2, JB(N+2).1, JB(N+2).2 adopt negative warp let-off and supply yarn on demand creel.

[0028] The present invention will be further described below by a specific embodiment:

[0029] See also Figure 2As shown, the manufacturing method of the present invention can produce a double jacquard warp knitted fabric of a composite structure, and the double jacquard warp knitted fabric of the composite structure includes a functional yarn layer 1, an elastic structure layer 2, a bottom pattern layer 3 and a pattern comb layer 4, and the functional yarn layer 1, the elastic structure layer 2, the bottom pattern layer 3 and the pattern comb layer 4 are arranged in sequence from bottom to top; the elastic structure layer 2 is formed by one of the GB (N+3) and GB (N+4) looping combs in the machine as an elastic layer, and is formed by spandex or spandex coated yarn; the functional yarn layer 1 adopts the weft insertion process of the GB (N+5) looping comb in the machine. The functional yarn layer can use functional yarns such as warm yarns or ice yarns.

[0030] The jacquard effect of the bottom pattern layer 3 in the present invention is different from the jacquard effect of the double jacquard single needle bed on the market. The layers reflected by the normal comb on the cloth surface are consistent with the front and back relationship of the runway. The front jacquard yarn must be in front of the rear jacquard yarn. The front jacquard can produce a solid color effect, and the front jacquard yarn covers the front of the rear jacquard. The two jacquards of the present invention are in front of the yarn pressing plate. The front and back relationship of the two jacquards can achieve the front and back position reversal of the yarn on the cloth surface through the yarn pressing plate and the different process needles, so that the cloth surface can simultaneously present more than two solid color structures.

[0031] PBN is selectively equipped in the pattern; the loop forming process includes open loop forming and closed loop forming, the basic yarn organization GB (N+5) is an optional comb, and it is used in the weft insertion mode; the yarn is selected according to the characteristics of the pattern. Different raw materials are used for the front yarn and the back yarn is made of soft and skin-friendly yarn. The different types of raw materials for the back and front can highlight the double-color effect. In addition, PB1-PBN can play a role in local reinforcement and decoration, with a strong three-dimensional sense and yarn Highly wear-resistant functional yarns (reflective yarn, fluorescent yarn, temperature-change yarn, light-change yarn and other functional yarns) can be used; the warp let-off of GB(N+3) and GB(N+4) is 600-3000 mm / ng, the warp let-off of JB(N+1).1, JB(N+1).2, JB(N+2).1 and JB(N+2).2 is 240-1500 mm / ng, and GB(N+5) is an optional comb with a warp let-off of 130-800 mm / ng when in use.

[0032] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
