Production method of moisture-absorbing and quick-drying hemp double-layer fabric

The blended yarn spinning is performed by pretreatment of hemp fiber and the introduction of other fibers. The double-layer structure is adopted to solve the problem of poor moisture absorption and quick drying performance of pure hemp fiber fabrics, and improve the overall performance of the fabric, making it more suitable for high-end clothing and functional fabrics.

AI Technical Summary

Technical Problem

Pure hemp fiber fabrics have room to improve their moisture absorption and quick drying performance, and at the same time they feel rough and have poor flexibility, which limits their application in high-end clothing and functional fabrics.

Method used

Hemp fiber pretreatment technology, including alkali treatment and low-temperature plasma treatment, improves the surface structure and hydrophilicity of the fibers. At the same time, Coolmax fiber, cross-section polyester fiber and silk fiber were introduced for blended yarn spinning, and a double-layer structure was adopted, with the inner layer being perforated and the surface layer being twill tissue. In conjunction with the use of pure cotton yarn, it was used to improve moisture absorption and quick drying performance.

Benefits of technology

Hemp fiber pretreatment and blended yarn technology significantly improves the moisture absorption and quick-drying properties of the fabric, improves the feel and flexibility, making the fabric more suitable for high-end clothing and functional fabrics.

Abstract

The invention belongs to the technical field of hemp double-layer fabrics, and relates to a production method of a moisture-absorbing and quick-drying hemp double-layer fabric. After the hemp fibers are pretreated, the surface structure is improved, the hydrophilicity is enhanced, sweat and moisture discharged by a human body can be rapidly absorbed, and the skin is kept dry and comfortable; the hemp blended yarn is spun by introducing moisture-conducting and quick-drying fibers, so that moisture can be quickly conducted and evaporated in the fabric, the quick-drying speed of the fabric is increased, and the wet feeling and discomfort are reduced; the spun silk fibers are introduced, so that the comfort of the fabric is improved, and meanwhile, the fabric has good hand feeling and comfort and does not irritate the skin.
