Description

Technical Field

[0001] The invention relates to the technical field of fabrics, and in particular to a hollow warm and soft fabric and a preparation method thereof. Background Art

[0002] As consumers' pursuit of quality of life continues to improve, the demand for high-performance thermal insulation materials in the modern textile market has shown a significant growth trend. Traditionally, the thermal insulation materials widely used by people mainly include natural fiber products such as wool and down. These materials are well-known for their excellent thermal insulation properties and can effectively help the human body resist the discomfort caused by cold weather. However, despite their good thermal insulation effect, they also have some disadvantages that cannot be ignored: on the one hand, these natural materials are often thick and heavy, and may not feel flexible enough to wear; on the other hand, the cleaning and maintenance process is relatively complicated and cumbersome, especially for those products that are easy to deform or require special care.

[0003] However, current fabric products cannot provide both light weight and warmth retention performance. Products with good warmth retention performance are often thicker, while light and comfortable products often have poor warmth retention performance.

[0004] In view of this, there is an urgent need for a hollow warm and soft fabric and a preparation method thereof. Summary of the invention

[0005] The purpose of the present invention is to provide a hollow warm and soft fabric and a preparation method thereof in view of the deficiencies in the prior art.

[0006] To achieve the above object, the technical solution adopted by the present invention is:
