Description

Technical Field

[0001] The utility model relates to the field of textiles, and particularly relates to a double-layer knitted fabric with one side thick and one side thin. Background Art

[0002] With the increasing requirements of clothing design manufacturers for knitted fabrics, double-layer knitted fabrics have begun to be used in the market. Generally speaking, double-sided knitted fabrics have soft texture, moisture absorption and breathability, excellent elasticity and extensibility, and their producibility.

[0003] Single-sided and double-sided knitting have different knitting methods, including dense needles and mesh bottoms. The two sides of the double-layer knitted fabric woven with a mesh bottom can be separated, but those woven with dense needles cannot be separated, and only the thickness can be felt. Single-sided fabrics generally refer to weft plain weave, and double-sided fabrics are like double rib (interlock) weaves. Generally speaking, both sides of double-layer knitted fabrics are the same. However, in actual use, for double-layer knitted fabrics with the same front and back sides, if they are outer-worn double-layer knitted fabrics, the back side cannot fit the skin well, resulting in poor comfort. If they are inner-worn double-layer knitted fabrics, they look like underwear, and an extra outer garment is needed to go out. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a double-layer knitted fabric with one side thick and one side thin. The front side of this double-layer knitted fabric has the rugged, smooth and fashionable feeling of outer-worn clothes, and the back side has the fitting, delicate and comfortable feeling of underwear as well as the heat preservation effect, so that the double-layer knitted fabric has the effects of two different fabrics at the same time.

[0005] In order to solve the above problems, the following technical solutions are adopted:

[0006] A double-layer knitted fabric with one side thick and one side thin is woven by a double-layer loom. The double-layer knitted fabric includes a front side and a back side, and is characterized in that: the double-layer knitted fabric takes 4 courses as a cycle, wherein the 1st and 2nd courses are lower single edges, the 3rd course is tuck stitch, and the 4th course is upper single edge; the lower needle cylinder of the double-layer loom uses a 28-pitch, and the upper needle cylinder uses a 14G thick pitch; the front side of the double-layer knitted fabric is woven with the 1st and 2nd courses, and the woven yarn is a siro-spun acrylic viscose yarn of 50S / 1; the back side of the double-layer knitted fabric is woven with the 4th course, and the woven yarn is a compact-spun pure cotton yarn of 26S; the front side and the back side of the double-layer knitted fabric are woven together with the 3rd course.

[0007] In the above double-layer knitted fabric, the front side is woven with siro-spun acrylic viscose yarn of 50S / 1, which can make the front side have a better rough, smooth and fashionable feeling; the back side is woven with compact-spun pure cotton yarn of 26S, which can make the back side have the comfortable feeling of being close-fitting and delicate like underwear and the heat preservation effect; the 3rd course of weaving serves as the transition between the front and back sides of the weaving, enabling the double-layer knitted fabric to have two different fabric effects while also having a certain elasticity between the front and back sides.

[0008] In the preferred embodiment, the weaving yarn of the 3rd course is 40D spandex.

[0009] In a further preferred embodiment, the coil length of the 40D spandex is 110MM / 100G.

[0010] In the preferred embodiment, the coil length of the siro-spun acrylic viscose yarn is 290MM / 100G.

[0011] In the preferred embodiment, the compact-spun pure cotton yarn is treated by a yarn steaming device.

[0012] In the preferred embodiment, the coil length of the compact-spun pure cotton yarn is 185MM / 100G.

[0013] In the preferred embodiment, the 4th course of weaving on the back side of the double-layer knitted fabric is carried out, and the 26S compact-spun pure cotton yarn for weaving is fed in with double yarns.

[0014] In the preferred embodiment, the machine size of the double-layer loom is 34 inches.

[0015] In a further preferred embodiment, the diameter of the cylinder of the double-layer loom is 34 inches.

[0016] The beneficial effects of the present utility model are as follows: The front side of this double-layer knitted fabric has the rough, smooth and fashionable feeling of outerwear, and the back side has the comfortable feeling of being close-fitting and delicate like underwear and the heat preservation effect, enabling the double-layer knitted fabric to have two different fabric effects at the same time. The specific value of the heat preservation effect of the present utility model is detected to have a maximum temperature rise value of 8.5 and an average temperature rise value of 3.2 within min for the moisture absorption and heat generation performance, and the surface hydrophobicity is 4 levels.
