Description

Spinning process for silky soft yarn, yarn and cloth

Technical Field

The invention relates to the field of spinning, in particular to a spinning process for silk soft spinning soft yarn, yarn and cloth.

Background

With the improvement of living standard, the requirement of people on the wearing comfort of clothes is higher and higher. Among them, the pursuit of "softness" of cloth is a big theme. In order to realize 'softness', besides the common softening treatment of cloth, the yarn twist in the industry also puts new requirements: a yarn with as low twist as possible is used to obtain a fabric with good "softness". Generally, the twist factor of the cotton yarn for knitting is 280-360, the twist factor of the cotton yarn for weaving is 290-430, and when the twist factor of the cotton yarn is lower than 280, the dynamic strength of the low-twist yarn is sharply reduced in the spinning section of the spinning process according to the current ring spinning process, so that the dynamic tension of the yarn in the spinning section is greater than the dynamic strength, the yarn is broken, and the continuous production is difficult. In addition, when the twist of the yarn is reduced, the quality indexes such as the yarn strength and the hairiness are deteriorated.

The cotton knitted fabric is an important raw material for knitted clothing, particularly underwear products, and compared with chemical fiber products, the cotton products have the defects of poor hand feeling and low dye uptake. The current solutions to the above problems are usually to increase the softness and dye uptake by adding chemical adjuvants which are significantly irritating to the skin, especially to infants and young children.

Therefore, a new spinning process is needed, which can utilize the existing spinning equipment to produce soft yarns and fabrics with significantly improved dye uptake.
