Problems solved by technology

If the hemp fiber is dyed first, the hemp fiber needs to be preserved and degummed before dyeing, and the amount of pectin in the hemp fiber after the treatment of health preservation and degumming is seriously removed, which will directly affect the strength of the roving, and eventually cause the spun yarn or spun yarn to be unable to be spun Greatly reduced strength
Moreover, due to the uneven fiber thickness of the roving itself, the spun yarn also has irreversible unevenness, and frequent end breakages will occur during spinning, which directly affects the appearance flatness and pilling of the final hemp fabric
If the traditional route of "dyeing first and then spinning" is used, it is more difficult to prepare high-count yarns, and it is impossible to prepare protein fiber / hemp fiber blended fabrics with smooth, soft, soft and hazy shades.

Abstract

The invention relates to the technical field of blended fabrics, in particular to a protein fiber / hemp fiber blended fabric. The fabric is made of the tops obtained after protein fibers are pretreated, neutralized, cleaned, combined with wool, combed, and drawn, and the hemp fibers obtained after curing, carding, combing, and drawing are drawn and then drawn again. After combing, drawing, spinning roving, spinning spun yarn, dyeing and finishing, the obtained protein fiber / hemp fiber blended dyed yarn is prepared, and then the obtained protein fiber / hemp fiber blended dyed yarn is woven again to obtain grey fabric, and then The grey fabric is prepared after finishing, and the fabric weight is 180‑400g / m 2 . It also includes a production process for a protein fiber / hemp fiber blended fabric. The fabric made by the production process of the present invention not only has health care functions such as antibacterial, antibacterial, antibacterial, skin care and body strengthening, and moisturizing the skin, but also has high strength of the fabric and a surface of the fabric. Flat, soft, good moisture absorption and breathability, full of luster, good UV protection, good antibacterial and antibacterial properties, unique appearance, soft and hazy color.

Description

technical field [0001] The invention relates to the technical field of blended fabrics, in particular to a protein fiber / hemp fiber blended fabric and a production process thereof. Background technique [0002] In recent years, with people's strong demand for personalized, high-grade and diversified clothing, more and more attention has been paid to soft, comfortable and functional fabrics. Hemp fiber is one of the softer types of fibers. Its fineness is only one-third of that of ramie, which is equivalent to that of cotton and hemp. Comfortable. Hemp planting is simple, time-saving and labor-saving; hemp can be grown all over my country, especially suitable for hillside, wasteland and saline-alkali land. Since synthetic fibers are made of petroleum, coal, natural gas, etc., their resources are non-renewable and energy consumption is serious. Therefore, renewable and recyclable biological resources have increasingly become the focus of human attention. [0003] Hemp fiber...
