A square twill terry fabric and its manufacturing method

Abstract

The present invention discloses a square twill terry fabric, which has a single-sided six-track twill tissue structure, and the knitting pattern takes 27 courses as a cycle. The square twill terry fabric adopts a single-sided six-track twill tissue structure, and the arrangement combination of loop formation, tucking and float lines makes the front of the fabric have clear lattice patterns. Due to the drafting of the intermediate connecting yarn, the loop lengths of some terry loops on the back are different, and the terry loops with larger loop lengths are arranged in straight strips; in the manufacturing method of the square twill terry fabric, the tension of the yarn input into the knitting equipment is further limited, so that the yarn is easy to bend and twist, the loop structure is uniform, and the fabric surface is smooth. The present invention also discloses a manufacturing method of a square twill terry fabric.

Technical Field

[0001] The present invention relates to the field of fabrics, and particularly to a check twill terry fabric and a manufacturing method thereof. Background Art

[0002] After the back side of the terry fabric is brushed, a brushed fabric with a fluff layer is obtained. The yarn composition of the terry fabric is: using polyester filament, polyester / cotton blended yarn or nylon filament as the ground yarn, and using cotton yarn, acrylic yarn, polyester / cotton blended yarn, acetate fiber yarn, air-jet spun chemical fiber yarn, etc. as the terry yarn. The characteristics of the terry fabric are that the terry is fluffy and the fabric surface is thick, and it is widely used in spring, autumn and winter clothing.

[0003] The front side of the terry cloth is a smooth plain stitch coil or rib coil, and the coil lengths of the terries on the back side are usually the same. Therefore, the feel of the front and back sides of the fabric is too single. In addition, how to produce fabrics with different fabric surface effects based on the existing single-sided sweatshirt machines is one of the common technical problems for those skilled in the art.

[0024] The advantages and beneficial effects of the present invention are as follows:

[0025] This square twill terry fabric uses a single-sided six-track twill tissue structure. The arrangement and combination of loop formation, tucking, and float yarns make the front of the fabric have clear grid patterns. Due to the drafting of the intermediate connecting yarn, the loop lengths of some of the terry loops on the back are inconsistent, and the terry loops with larger loop lengths are arranged in straight strips.

[0026] In the manufacturing method of the square twill terry fabric, the tension of the yarns input into the knitting equipment is further limited, making the yarns easy to bend and twist, with a uniform loop structure and a smooth fabric surface. Description of the Drawings

[0027] Figure 1 is the process knitting diagram of the square twill terry fabric in the embodiment;

[0028] Figure 2 is the knitting needle arrangement diagram of the square twill terry fabric in the embodiment;

[0029] Figure 3 is the cam configuration diagram of the square twill terry fabric in the embodiment. Detailed Embodiments

[0030] The following combines the drawings and embodiments to further describe the detailed embodiments of the present invention. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and cannot be used to limit the protection scope of the present invention.

[0031] Selection of Yarns

[0032] The first yarn is the terry inner yarn. The fineness and yarn length of the terry inner yarn are one of the main factors determining the fabric thickness. The coarser the terry inner yarn and the longer the yarn length control, the larger the loop length of the fabric terry and the increase in fabric gram weight. However, if the terry inner yarn is too thick and / or the yarn length is too small, it is not conducive to the bending and twisting of the yarn.

[0033] The 20th, 23rd, and 26th paths of the second yarn and the third yarn are the surface layer yarns, and the remaining third yarns are the intermediate connecting yarns. There are differences in fineness and / or yarn composition between the second yarn and the third yarn. The 2nd, 5th, 8th, 11th, 14th, 17th paths and the 20th, 23rd, 26th paths of the surface layer form stripe patterns alternating in the first direction; in the complete pattern tissue, the connecting parts between adjacent cycles are interwoven by the second yarn and the third yarn. The cycle and the connecting part form a 9*9 complete pattern tissue. Among them, the second yarn is diagonally connected, and the third yarn has more loops, which is different from the 2nd, 5th, 8th, 11th, 14th, 17th paths composed of the second yarn loops on the front of the above fabric, forming stripe patterns alternating in the second direction. The first direction and the second direction correspond to the warp direction and the weft direction respectively. The combination of the stripe patterns in the two directions finally presents a grid pattern effect on the fabric surface.

[0034] Due to the pulling influence of the surface yarn, the loop length of the back loop changes regularly. The loops with larger loop length are distributed in straight strips, and the extension direction of the straight strips is consistent with the second direction mentioned above. The straight strips of loops with larger loop length are opposite to the connecting parts between the loops.

[0035] Fiber composition of yarn

[0036] The fiber composition of the yarn can also affect the checkered pattern and skin-friendly properties of the fabric: when the yarn composition is different, the second yarn is cotton yarn, and the second yarn is thicker than the third yarn, the checkered pattern on the front of the fabric is composed of cotton yarn loops, and the front of the fabric is more skin-friendly. The greater the difference in thickness between the second yarn and the third yarn, the more obvious the checkered pattern on the front of the fabric will feel.

[0037] Furthermore, the fiber composition of the yarn also determines the different dye uptake rates. By using dyes with different dye uptake rates for cotton and polyester, the difference in color depth of the dyed fabric can make the checkered visual effect on the front of the fabric more obvious.

[0038] Yarn count and yarn length

[0039] The yarn count and yarn length determine the density and texture of the fabric. The preferred 30-40S polyester-cotton-viscose blended yarn and parallel yarn make the vertical stripes on the front of the fabric clearer. The yarn count and yarn length are preferred, and the resulting fabric is suitable for making spring and autumn clothing. Example
