Abstract

The invention relates to hemp fabric and a preparation method thereof. The hemp fabric is formed by blending cotton fibers serving as warp yarn and hemp cotton yarn serving as weft yarn, wherein the weight ratio of the cotton fibers to the hemp cotton yarn is (56-60):(40-44). The invention further provides a preparation method of the hemp fabric. The preparation method comprises the steps that the cotton fibers and the China-hemp cotton yarn serve as raw materials and are sequentially subjected to a warping process, a sizing process, a denting process and a weaving process to obtain the hemp fabric, wherein in the sizing process, a used sizing agent comprises the following components in parts by weight: 5.0-10.0 parts of vegetable gum, 70.0-80.0 parts of rubber powder and 20.0-30.0 parts of composite starch, and the solid content of the sizing agent is 13.0+/-1%. The obtained hemp fabric is not prone to wrinkling and shrinking, and is resistant to ultraviolet rays and capable of inhibiting bacteria.

Description

technical field [0001] The invention relates to the technical field of textile production, in particular to a hemp fabric and a preparation method thereof. Background technique [0002] Most people are very particular about clothes nowadays. With the progress of society, people's living standards are also constantly improving, and the requirements for basic necessities of life are gradually getting higher. Hemp fabric has many functions such as moisture absorption, breathability, comfort, heat dissipation, anti-mildew, antibacterial, anti-radiation, anti-ultraviolet, sound-absorbing and other functions. Market demand for functional fabrics. However, the length of the hemp fiber is uneven, the hairiness is many, hard and long, and impurities such as pectin and lignin in the hemp fiber make the bending and torsional rigidity of the hemp fiber large, and the fiber is not easy to cohere, affecting the quality of the hemp fiber. It guarantees the spinnability of hemp; cotton fi...
