Description

Technical Field

[0001] The invention belongs to the technical field of clothing fabrics, and in particular relates to a five-layer air layer fabric and a preparation method and application thereof. Background Art

[0002] For a long time, the surface materials of air layer fabrics on the market are mostly cotton staple yarns, and the weaving structure is mostly a sandwich structure of outer layer, middle layer and inner layer, thus forming an air layer in the fabric to keep warm; especially used in autumn and winter clothing, it has good warmth retention. However, this type of fabric also has some disadvantages, such as the poor anti-pilling effect and anti-snagging performance of the cotton staple surface; and the sandwich structure design is prone to problems such as poor elasticity, insufficient support and poor wrinkle resistance. Therefore, the development of air layer fabrics with better comprehensive performance is a problem that R&D personnel pay more attention to.

[0003] For example, CN117306078A discloses an air layer thermal insulation fabric, comprising an inner layer, an intermediate layer, and a surface layer, wherein the inner layer and the surface layer are connected together through the intermediate layer, wherein the surface layer is woven from cotton yarn, the intermediate layer is woven from DTY polyester fiber, and the inner layer is woven from FDY polyester fiber, wherein the cross section of the FDY polyester fiber is a circular hollow cavity structure. By weaving with FDY polyester fiber having a circular hollow cavity structure, the moisture absorption, air permeability, and thermal insulation of the fabric are improved; however, the thermal insulation effect of the air layer thermal insulation fabric needs to be further improved, and the thermal insulation rate is low; and due to the use of cotton yarn and a sandwich structure design, there are still problems of poor anti-pilling effect, poor anti-snagging performance, poor elasticity, and poor wrinkle resistance.

[0004] Therefore, developing an air layer fabric with good warmth retention effect, anti-pilling, anti-snagging, good elasticity and anti-wrinkle is a problem to be solved urgently in the field. Summary of the invention
