Ultralow-twist velvet cotton fabric and weaving and dyeing process thereof

Abstract

The invention discloses an ultralow-twist velvet cotton fabric. A weaving and dyeing process of the ultralow-twist velvet cotton fabric comprises performing compact and siro spinning on a yarn A composed of 50-100% of long-staple cotton and 0-50% of combed cotton, and a yarn B composed of 0-50% of long-staple cotton and 50-100% of combed cotton to obtain a pure cotton ultralow-twist yarn with a degree of twist of 0-30 twist per inch; weaving the pure cotton ultralow-twist yarn solely or with other yarns into ultralow-twist velvet cotton raw fabric; performing dyeing, aftertreatment, fixation,softening and shaping processes on the ultralow-twist velvet cotton raw fabric to obtain the ultralow-twist velvet cotton fabric. The invention also provides a preparation process of the ultralow-twist velvet cotton fabric. The prepared ultralow-twist velvet cotton fabric achieves the excellent properties of good overall fluffy touch feeling, soft and dry hand feeling, rapid drying after absorbingwater during washing and fabric twist and twilling reduction, and is less prone to losing color, thereby meeting the demands of people on high-grade fabrics.

Description

technical field [0001] The invention belongs to the technical field of knitted fabric manufacturing, and in particular relates to an ultra-low-twisted blue velvet cotton fabric and its weaving, dyeing and finishing process. Background technique [0002] The textile industry is one of the traditional industries in our country and has a relatively important economic status. According to different market demands, knitted fabrics are divided into pure cotton knitted fabrics, cotton-polyester blended knitted fabrics, polyester knitted fabrics, silk knitted fabrics, and polyester-silk blended knitted fabrics. Cloth, etc., before being processed into clothes, these knitted fabrics need to undergo a series of processing operations, such as pretreatment of boiling and bleaching, dyeing, post-treatment of color fixing and softening, etc. With the improvement of people's living standards, the requirements for the comfort of fabrics are also getting higher and higher, especially for inf...

AI Technical Summary

Problems solved by technology

Long-staple cotton fabric is a common fabric that can be applied to infant clothing. However, the softness, bulkiness and hygroscopicity of the fabric obtained by the existing weaving process are not up to the requirements. The existing dyeing process of fabrics used by young children still has the problem of easy fading, which has a great impact on the skin health of infants and young children

In the existing fabric weaving process, the twist of the yarn is generally adjusted to be high, which will affect the softness of the fabric. When the twist is too low, the structure of the yarn will be poor, which will easily lead to the use of the fabric. The lifespan is limited. At present, there is no technology in the market to prepare ultra-low-twisted blue velvet cotton with long-staple cotton and overcome the poor strength and low lifespan. In addition, cotton fabrics are also required to have good softness. Most of the fabrics are softened with silicon-containing soft oil, which affects the soft and dry feel of the cotton fiber itself
