The weft knitting three-color jacquard fabric with the thickness is woven by the technical scheme, the sandwich structure is combined with the single-layer jacquard, the color of the fabric is changed after dyeing, and the fabric has the heavy feeling and simultaneously realizes low gram weight.

Description

Weft-knitted three-color jacquard fabric and production method thereof

Technical Field

The invention belongs to the technical field of weft-knitted fabrics, and particularly relates to a weft-knitted three-color jacquard fabric and a production method thereof.

Background

The three-color jacquard fabric is a high-grade garment fabric with gorgeous colors and changeable patterns. The three-color jacquard fabric in the prior art has the problems of light weight, no thickness sense and unsuitability for autumn and winter clothing. If the yarn with the high D value is adopted for high-density weaving, the requirements of thickness feeling and gram weight are met, but the problem that the unit price is high and the yarn is not suitable for mass consumption exists.

Disclosure of Invention

In view of the above technical problems in the background art, it is desirable to provide a weft-knitted three-color jacquard fabric and a production method thereof, wherein the weft-knitted three-color jacquard fabric can present a jacquard effect, rich colors, integral molding, and a high technological and fashionable feeling of air permeability.

In order to achieve the above object, in a first aspect of the present invention, the inventors provide a method for producing a weft-knitted three-color jacquard fabric, comprising an upper surface, an intermediate layer and a lower surface; the weft-knitted three-color jacquard fabric is circularly knitted by adopting an 8-stitch needle of a weft-knitted double-faced jacquard; the dial needles adopt a 12-row needle arrangement mode; the needle cylinder needle adopts a 11 needle arrangement mode;

the dial triangle is configured as follows:

∪∨───∨──

─∨──∪∨──

dyeing the grey cloth obtained by weaving, and forming different colors in three different areas to obtain the weft-knitted sandwich three-color jacquard fabric with three colors on the lower surface.

Further, the first and second yarns have different dye affinities for a particular dye.

Furthermore, the first yarns are made of polyester, and the second yarns are made of cotton yarns.

Further, a piece of spandex was mixed in during the weaving of the lower surface.

Further, in the weaving process, the 2 and 6 paths of dial needles are all out, and the 2 and 6 paths of cylinder needles do not participate in the work.

In a second aspect of the invention, the inventor provides a weft-knitted three-color jacquard fabric produced by the production method of the first aspect of the invention.

Different from the prior art, the technical scheme combines the sandwich structure with the single-layer jacquard, weaving weft knitting sandwich three-color jacquard gray fabric with thickness, and not only realizes the change of the color of the fabric after the gray fabric is dyed, but also realizes the low gram weight while the fabric has heavy feeling. Printing after weaving is avoided, working procedures are saved, and the purposes of energy conservation and emission reduction are achieved.

Detailed Description

The following is a detailed description of the production method of the weft-knitted tricolor jacquard fabric according to the first aspect of the invention and the weft-knitted tricolor jacquard fabric according to the second aspect.

Example 1 weft-knitted three-color jacquard fabric

Circularly weaving by adopting a weft knitting double-sided jacquard machine with 8 needle paths, and carrying out computer jacquard; the jacquard type is 34' 28G 72G. The dial of the weft knitting double-sided jacquard adopts a 12-row needle mode; the needle cylinder needle adopts a 11 needle arrangement mode;

the dial triangle is configured as follows:

∪∨───∨──

─∨──∪∨──

the cylinder needle adopts a computer jacquard automatic triangle, and adopts the craftsman's intention shown in figure 1.

Specifically, in the weaving process, the stitch arranging mode and the craftsman intention are input into computer software, and raw material yarns are connected into corresponding yarn paths in a matching mode to be woven, so that the white blank of the weft-knitted sandwich three-color jacquard fabric can be obtained.

In this embodiment, the first yarn is polyester and the second yarn is cotton. In other embodiments, yarns made of materials such as nylon, hemp, wool and the like can be used in combination with different specific dyes.

In the weaving process, the 2 and 6 paths of dial needles are all out, and the 2 and 6 paths of cylinder needles do not participate in the work.

And the No. 2 and No. 6 paths adopt 150D terylene mixed with 30D spandex to form a loop on the upper surface.

And the 3 rd path and the 7 th path are weaved on the lower surface by adopting 75D terylene and 20D spandex and the 4 th path and the 8 th path to form loop, and the 4 th path and the 8 th path are formed on the lower surface by adopting cotton yarn to form floating thread and loop.

The 1 st and 5 th ways adopt 50D polyester fish silk to be tucked in the middle layer, the upper surface and the lower surface of the grey cloth are connected, and meanwhile, the function of an air layer is achieved, so that the heat retention property can be improved.

The woven weft-knitted three-color jacquard fabric grey cloth combines a sandwich and a single-layer jacquard, and comprises an upper surface, a middle layer and a lower surface, wherein the lower surface is the front surface of cloth, and comprises a cotton yarn area, a terylene area and a cotton yarn and terylene mixed area, and the front surface of the grey cloth shows the technical effect of three colors after dyeing cotton yarns and terylene by using specific dye. Meanwhile, the fabric is of a sandwich structure, has a certain thickness and is light in gram number. After dyeing, the change of the fabric color is realized, the fabric has a heavy feeling, and the low gram weight is realized. Printing after weaving is avoided, working procedures are saved, and the purposes of energy conservation and emission reduction are achieved.

It should be noted that, although the above embodiments have been described herein, the invention is not limited thereto. Therefore, based on the innovative concepts of the present invention, the technical solutions of the present invention can be directly or indirectly applied to other related technical fields by making changes and modifications to the embodiments described herein, or by using equivalent structures or equivalent processes performed in the content of the present specification and the attached drawings, which are included in the scope of the present invention.
