The development history of composite spinning technology can be traced back to the early stages of the textile industry. With the continuous advancement of science and technology, composite spinning technology has also been further innovated and developed. Modern composite spinning technology can not only realize the mixed spinning of different fibers, but also realize composite methods such as layered spinning and staggered spinning of different fibers to obtain more complex and diversified spinning products. At the same time, with the continuous improvement of the functionality of textiles, composite spinning technology has also been widely used in functional spinning.

[0003] The surface fabric is made of two sets of yarns, 130D / 24F DTY and 20D spandex, and the base fabric is made of two sets of yarns, 40SPRESWARMAC / R 60 / 40 and 100D / 144F DTY. The special selection of raw materials determines that this fabric is destined to be extraordinary; in terms of technology, the nine production processes of shrinking, pre-setting, dyeing, drying, raising, combing, shearing, finished product setting and laminating lay the foundation for the unique feel of the fabric; in terms of performance, this fabric has a soft feel, good thermal insulation, and is resistant to water and soap washing. Summary of the invention
