Problems solved by technology

The technical solutions provided by these inventions can maintain the unidirectional moisture-wicking effect for a long time, but like most other existing inventions, they are all knitted fabrics, and except for the unidirectional moisture-wicking function, they do not make full use of other characteristics of polypropylene fibers, and if they are outside If the surface is directly made of hydrophilic natural fibers, its quick-drying performance will be relatively poor

Abstract

The invention discloses a process for preparing a unidirectional moisture-permeable light heat-insulating tatting double-layer fabric and belongs to the field of functional textiles. The unidirectional moisture-permeable light heat-insulating tatting double-layer fabric is a double-layer structure tatting fabric, wherein warp yarn is interwoven with face weft through a method of insidewarp connection, namely a down-up connection method. A surface layer is one of polyester special-shaped section water absorption fiber or ku si mian fiber, and a lining is made of polypropylene hollow fiber dyed yarn. After an obtained gray fabric undergoes cold batch pretreatment, disperse dye overflow dyeing, dry sizing and galling treatment, the final unidirectional moisture-permeable light tatting double-layer fabric is obtained. On the one hand, the fabric performs dewatering and moisture permeation, on the other hand, the fabric absorbs water and discharges moisture, and thus the fabric has functions of unidirectional moisture permeation. Due to functional characteristics of a hollow polypropylene fiber and a galling process adopted for the process, the fabric has a good heat insulation function while upgrading an inner layer moisture permeation function.

Description

technical field [0001] The invention relates to the field of functional textiles, in particular to a preparation process of a unidirectional moisture-conducting light-weight and heat-retaining woven double-layer fabric. [0002] technical background [0003] The unidirectional moisture-wicking function of the fabric is developed on the basis of moisture-wicking and quick-drying, which means that moisture and heat are quickly transferred from the inner layer of the fabric (skin contact layer) to the outer layer of the fabric (air contact layer) and evaporate quickly, and the moisture , The heat does not stay in the inner layer. This type of fabric does not stick to the skin, is breathable and quick-drying, and is very comfortable to wear. Unidirectional moisture-wicking fabrics generally use different hydrophilicity and hydrophobicity of the inner and outer fabrics, that is, the outer layer of the fabric is hydrophilic and the inner layer is mostly hydrophobic, and sweat is t...
