Problems solved by technology

However, when making clothes with gradient color fabrics as clothing materials, especially for summer clothing, when the knitting density of the clothing material is small, the lighter dyed part is easy to transmit light, reflecting the skin color of the next-to-body clothing or the wearer, causing embarrassment; When it is big, although the light-colored part will not transmit light, the material itself is not breathable enough, so it is not comfortable enough to wear
[0003] At present, in the field of textiles, there are several ways to produce gradient color fabrics. One is to dye the yarns first, and then arrange the colored yarns according to the designed pattern for weaving; The second is to use yarns of different materials to weave the dyed yarns according to the designed flower shape, and then dye them. Because the coloring degrees of yarns of different materials are different, a gradient dyeing effect can be formed, but Due to the different materials of weaving dark and light-colored yarns, the materials of the dark-colored and light-colored parts of the woven fabric are quite different, and there is no integrity, which affects the subsequent use of the fabric, and is not suitable for large-scale industrial production.
The third is to print the dye on the gray fabric of the fabric to form a gradient color effect by printing, but the process control of the gradient color printing and dyeing process is complicated, and the printing and dyeing effect is relatively rigid, and the printing and dyeing depth is not easy to control, which is not as natural as the direct dyeing method
Moreover, the above printing and dyeing methods are complicated, the dyeing time is long, the water consumption is large, and more production sewage is produced, which causes greater pressure on the environment.

Embodiment 1

[0027] Embodiment 1 A kind of production method (cotton) of gradient knitted fabric

[0028] a) Weaving: Select 30 cotton compact spun pure yarns and weave them on a 24-needle flat knitting machine.

[0029] Use a flat knitting machine to weave, adjust the stitch to 120 when weaving the coil part of the dark stripe, the fabric coil density of the dark stripe part is small, and then adjust the stitch to 100 when weaving the coil part of the medium depth stripe, the medium depth The fabric loop density of the striped part is medium. Finally, adjust the mesh to 60 when weaving the loop part of the light-colored striped part. The fabric loop density of this light-colored striped part is the largest.

[0030] b) Pre-treatment, during the fabric weaving process, the fabric will retain some unevenly distributed tension, size, oil and impurities, etc., so it needs to be removed by pre-treatment. The pre-treatment uses 1.5% neutral oil-removing refining agent and 2% soda ash, the bath...

Embodiment 2

[0034] Embodiment 2 A kind of production method of gradient knitted fabric (polyester)

[0035] a) Weaving: Select 32 counts of pure polyester yarn and weave it on a 28-needle circular machine.

[0036] When weaving, the circular machine adjusts the yarn feeding wheel. The larger the yarn feeding amount, the longer the coil length and the lower the density; at the same time, the pressing needle depth can be adjusted. The deeper the pressing needle, the larger the coil and the lower the density. Conversely, the greater the density. The length of one hundred coils is 100mm, the shorter the fabric density, the tighter the fabric, it is easier to dye light colors;

[0037] b) Pre-treatment, during the weaving process of the fabric, the fabric will retain some unevenly distributed tension, oil and impurities, etc., so it needs to be removed by pre-treatment. The pre-treatment uses 0.1% neutral oil-removing refining agent and 0.1% Soda ash, the bath ratio is 1:17, wash with 70℃ hot ...

Embodiment 3

[0041] Embodiment 3 A kind of production method of gradient knitted fabric (nylon)

[0042] a) Weaving:

[0043] The warp knitting machine changes the coil weaving density by changing the crimp drawing density and tension. Change the crimping and pulling speed, the normal winding speed is 10cm per minute, after adjustment, the winding speed becomes 7cm and 13cm, and the fabric density becomes larger at 7cm winding speed for 1 minute weaving. The fabric density becomes smaller and the length of one hundred loops is 185mm. Weaving 10cm in 1 minute is the middle fabric density and the length of one hundred loops is 255mm.

[0044] Adjust the tension, the normal weaving tension is 1.2 times, adjust the tension size 1.0 times and 1.5 times, each weaving for 1 minute, then the part of 1.0 times of tension is the part with the smallest fabric density. The length of one hundred coils is 180mm, and the length of one hundred coils centered at 1.2 times is 230mm. The denser the fabric...

Abstract

The inventor provides a gradient color knitted fabric and a production method thereof. The production method includes weaving and dyeing steps. The knitted fabric having a difference in coil weaving density is woven by yarns. The manufacturing process is simple, the dyeing time is short, and the environment is less polluted. According to the prepared gradient color knitted fabric, the light colorportion has a high knitting density and is easy to transmit light, and the dark color portion has a low knitting density and is ventilated and breathable. The gradient color knitted fabric has personalized gradient color and is suitable for use in various clothes, especially in summer clothes.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a gradient color knitted fabric and a production method thereof. Background technique [0002] The surface of the gradient color fabric presents a color gradient effect, and the surface presents a soft and smudged color, which is full of mysterious and romantic atmosphere. The use of color gradients brings effects such as ups and downs, rhythms, and layers to the fabric surface, and can show color gradients in nature and The magical charm in life has been more and more sought after by the market to meet the individual needs of different groups of people. However, when making clothes with gradient color fabrics as clothing materials, especially for summer clothing, when the knitting density of the clothing material is small, the lighter dyed part is easy to transmit light, reflecting the skin color of the next-to-body clothing or the wearer, causing embarrassment; When it is large, althou...
