Description

Double weft inserted jacquard multi-comb warp knitted fabric and its weaving method

Technical field

The invention relates to a knitting method of warp knitted fabric and its fabric, in particular to a knitting method of jacquard multi-comb warp knitted fabric and its fabric.

Background technique

Transparent and delicate mesh effect is one of the most important qualities of high-end lace fabrics. Lace fabrics with these transparent and delicate meshes tend to have poor wearability, which is mainly manifested in swelling, bursting and poor anti-snagging properties, and it is difficult to withstand daily use or repeated washing and abrasion.

Conventional single weft inserted jacquard multi-comb warp knit fabrics, even if the mating design process is adopted, the mats must be mated on two adjacent courses to form a fuzzy mesh, and when weaving the transparent mesh, due to The horizontal connection of the weft inserted jacquard yarns is not enough, resulting in poor fabric strength, not resistant to repeated washing, and easy to snag and break during actual use. In addition, the conventional single weft inserted jacquard jacquard multi-comb warp knit fabric has only two and a half gauge jacquards on a single needle bed as weft inlay yarns, so the types of meshes that can be changed are limited; regardless of whether the mating basic structure is used, Most of the straight-knitted chains are pulled by unidirectional jacquard yarn and the loops are twisted and deformed, and the mesh is not correct and the strength is not enough.

With the continuous improvement of people's requirements for mesh fineness, style, permeability, etc., therefore, it is necessary to innovate in crafts and methods.

Summary of the invention

For the conventional multi-comb warp knitted fabric with weft inserted jacquard, there are only two half-gauge jacquard bars on a single needle bed as weft inserting yarns, and the mesh structure is less variable, insufficient strength, and insufficient permeability, etc. Disadvantages, a new process method is provided. Through the research and development of multi-bar warp knitting machines, four and a half-gauge jacquard-combed weft inlay yarns can be carried out on a single needle bed, which greatly enriches the variability of the mesh And enhance the wearability of the fabric.

To achieve the above objectives, the present invention adopts the following technical solutions: a method for knitting double-inserted jacquard jacquard multi-comb warp knitted fabrics, the double-inserted jacquard jacquard multi-comb warp knitted fabrics include ground net structure and fancy yarn structure The ground net structure includes a braided chain structure and an inlay weft yarn. When the ground net structure of the fabric is formed, four half-gauge jacquard bars are used as weft inlay yarns, so that the double-inserted jacquard At least two jacquard yarns are lined with each braided chain of the kart multi-comb warp knitted fabric.

Further, the four and a half-gauge jacquard bars can be arranged at any position of the warp knitting machine. For example, the four and a half-gauge jacquard bars can be arranged in front, middle or back of the pattern comb working line of the warp knitting machine.

Further, the four half-gauge Jacquard bars can be independently controlled, and the yarn laying direction of the basic weave can be combined arbitrarily: all in the same direction or part of the same in the same direction.

Further, when the four jacquard combs are used for mat knitting, the basic chain numbers of the jacquard combs can be combined arbitrarily as required.

Further, the four jacquard bars can adopt various required yarn threading methods.

Further, the four jacquard combs are knitted in a non-continuous course to form a mesh with different numbers of needles.

Furthermore, the number of jacquard yarns in the same course across two adjacent braided chains can reach twice the number of jacquard bar basic traverse needles.

In addition, through the research and development of a Jacquard signal superimposition distribution system, the four and a half-number Jacquard bars are controlled by independent signals to move laterally, without interference with each other.

Through the research and development of the double let-off system of the jacquard bar, the yarns of the four jacquard bars are guaranteed to be fed according to actual needs.

Through the bar work line redistribution system, the yarns of the four jacquard bars can be accurately inserted into the loops.

Combining the four jacquard comb inlaid yarn craftsmanship design, weave various styles of mesh.

In an embodiment of the present invention: four half-number jacquard comb counter cushions, the basic chain number: two jacquard combs are 0-0/1-1//, and the other two jacquard combs are 1. -1/0-0//. The technical characteristics of the double-inserted jacquard mesh are: the jacquard yarn on the straight knitting chain pulls the ground yarn straight knitting chain from the opposite direction, the forces cancel each other, and the warp direction of the ground yarn straight knitting chain is kept as straight as possible. , The formed mesh is correct and beautiful.

The mesh strength of the four and a half jacquard bars is obviously increased, and the mesh effect with larger holes and more transparent can be designed.

Each horizontal jacquard connection point has two directions of jacquard yarn feeding, the connection point between the braided chains can be as few as one row, and the connection between the wales is very stable.

The invention has the following beneficial effects: on the conventional single-needle-bed multi-bar warp knitting machine with weft-inserted jacquard, only two half-machine jacquard bars are configured, and the present invention is equipped with four half-machine jacquard bars. Comb. By adopting the weaving method of the present invention, a transparent and stable ground net can be woven, and this kind of ground net presents a transparent appearance effect that cannot be achieved by ordinary meshes, and has good wearing performance. Combined with the special mating process of Double Jacquard, the mating process based on 0-0/1-1//, 1-1/0-0// is used as the base chain number, and there are up to 4 on each straight-knitted chain Weft inserted jacquard yarn. The number of jacquard yarns in the same course that spans between two adjacent braided chains can reach 2, and the yarns can be inlaid from different directions, making the straight knitting chain beautiful and strong.
