[0002] In prior art, autumn and winter knitted underwear fabric has been variously promoted and developed from the most common full cotton cotton knitted fabric of cotton sweater and trousers, mainly in terms of comfort and functionality, including development of antibacterial functional autumn and winter knitted underwear fabric, development of high-elasticity autumn and winter knitted underwear fabric, development of soft and comfortable autumn and winter knitted underwear fabric. For example, soft cashmere Lycra knitted fabric interweaves spandex on the basis of cotton knitted fabric, forms flexible high-elasticity comfort, and the fabric is brushed on both sides to form micro-embossed, improving softness and comfort. As another example, full cotton knitted underwear fabric is finished with antibacterial agent to form antibacterial function. However, many aspects of prior art need to be improved and further developed. For example, the disadvantage of soft cashmere Lycra knitted fabric is that spandex is easily damaged due to the embossed fabric, so the pile on the pile surface is not very dense. As another example, the antibacterial function of full cotton antibacterial finished knitted fabric is not washable.

[0003] The utility model aims at overcoming the above-mentioned shortcomings, providing a novel knitted fabric technical solution, which can give full cotton knitted underwear fabric the combination of long-lasting antibacterial and deodorant functions, flexible and comfortable spandex without damage, and dense pile on the surface of the fabric. SUMMARY

[0004] In order to overcome the disadvantage of poor washability of full cotton fabric after antibacterial finishing, the spandex interwoven with full cotton knitted fabric uses antibacterial and deodorant spandex in the newly launched functional spandex by spandex company. Since functional spandex has a small amount of functional substance microparticle powder melted in spandex, it has a certain impact on the strength of spandex, and spandex is easily damaged during processing. In order to intensify the pile on the pile surface, spandex may be damaged. Considering the above two factors, a new structure is designed to realize antibacterial and deodorant functions, elastic function and dense pile on the pile surface, and prevent spandex from being damaged during processing. Spandex is only interwoven on the inner surface of all loops on the reverse side of the fabric, so that the front of the fabric is knitted into a concave-convex structure, which can be deeply embossed to form a dense pile surface. The reverse side of the fabric is lightly embossed to prevent spandex from being damaged, and a less dense pile surface is formed.

[0005] The technical solution is as follows:

[0006] To develop an antibacterial elastic full cotton knitted underwear fabric. The fabric is composed of cotton yarn and spandex pile knitted structure, characterized in that the spandex is antibacterial and deodorant functional spandex, the knitted structure is a weft-knitted double-sided structure composed of a fabric front surface (2) and a fabric back surface (4), the fabric front surface is concave-convex, and the spandex loop (3) is only knitted in the loop of the fabric back surface, the pile is brushed micro-pile, the pile of the fabric front surface pile (1) is longer, and the pile of the fabric back surface pile (5) is shorter.

[0007] Further, the weft-knitted double-sided structure is a double-sided pearl stitch, and the fabric front surface is a tuck concave-convex structure.

[0008] Further, the spandex is only looped with all the back surface loops on the inner side of the back surface loop.

[0009] Further, the spandex is 30-40D antibacterial and deodorant functional spandex.

[0010] Further, the cotton yarn is 32-36 English cotton.

[0011] The fabric can also be combined with antibacterial finishing of the fabric, so that the fabric has stronger antibacterial property in the new use stage.
