Description

Technical Field

[0001] The utility model belongs to the technical field of textiles, and in particular relates to a cuprammonium pile knitted fabric and clothing. Background Art

[0002] Terry fabric refers to a knitted fabric with one or both sides covered by terry. It has the characteristics of soft feel, thick texture, good water absorption and warmth retention.

[0003] However, the common terry fabrics in the prior art often have the problem of relatively single functions, and cannot take into account excellent moisture absorption and heat release, warmth retention and high strength, and are difficult to meet the needs of consumers.

[0004] Therefore, in response to the above problems, there is an urgent need to develop a cuprammonium pile knitted fabric with excellent moisture absorption and heat generation, good warmth retention, high bursting strength and excellent moisture absorption and release effect. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cuproammonia pile knitted fabric and clothing. By limiting the fabric structure and the type of yarn used, the obtained cuproammonia pile knitted fabric has the characteristics of low cost, high bursting strength, excellent moisture absorption and heat generation, good thermal insulation, and softness and comfort. It is particularly suitable for making underwear, thermal clothing and other clothing.

[0006] In order to achieve the purpose of this utility model, the utility model adopts the following technical solutions:

[0007] In a first aspect, the utility model provides a cupro-ammonia fleece knitted fabric, wherein the front side of the cupro-ammonia fleece knitted fabric is a surface layer, and the back side is a terry layer, and the terry layer has a pile structure on a side away from the surface layer;

[0008] The surface layer and / or the terry layer contains blended yarn A, and the blended yarn A is a cuprammonium blended yarn.

[0009] The cross-section of cupra fiber is round, without skin-core structure. The fiber can withstand high stretching, and the monofilament produced is relatively thin, so the fabric feels soft, has a soft luster, and has a silk feel. The cupra fabric containing cupra fiber can be comparable to silk fabric in feel and drape, and has the advantages of soft luster, good moisture absorption and good breathability.

[0010] The cuproammonia pile knitted fabric provided by the utility model has a double-sided structure, with the front side serving as the surface layer and the back side serving as a terry layer with a terry structure. By limiting the surface layer and / or the terry layer to contain a blended yarn A, the blended yarn A being a cuproammonia blended yarn, and the terry layer having a velvet structure on the side away from the surface layer, the obtained cuproammonia pile knitted fabric has excellent moisture absorption and heat generation, warmth retention and high bursting strength. Moreover, since the terry layer with the velvet structure is close to the skin side when the cuproammonia pile knitted fabric is used, the warmth retention and comfortable softness of the obtained cuproammonia pile knitted fabric are further improved, making it very suitable for underwear and warm close-fitting clothing.

[0011] In the present invention, the "copper-ammonia blended yarn" refers to a blended yarn obtained by blending cuproammonia fiber and other fibers.
