Embodiment 1

[0025] A high-elastic and low-shrink elastic yarn fabric, the warp and weft yarns composed of three-core elastic yarns are woven with twill weave, and the elastic yarns are mixed with cotton fibers and twisted spandex elastic yarns and polyester elastic yarns, and the cotton fibers are carded separately. Fiber, spandex elastic yarn and polyester elastic yarn are made into staple fiber raw sliver and elastic silk raw sliver, the cotton fiber raw sliver and elastic silk raw sliver are plied and drafted three times to obtain a drafted sliver, and the drafted sliver is converted into a roving, The roving is ring spun to form a spun yarn, i.e. a stretch yarn. The weight percentage of spandex elastic yarn in the yarn core is 35%, the weight percentage of polyester elastic yarn in the yarn core is 65%, the spandex elastic yarn has a stretch ratio of 3.5, and the polyester elastic yarn has a stretch ratio of 1.5 For example, the thread densities of spandex elastic yarn and polyester e...

Abstract

The invention discloses three-core stretch yarn. The three-core stretch yarn comprises a yarn core and an external wrapping layer; the yarn core is wrapped by the external wrapping layer in a spiral mode; the yarn core is composed of polyurethane stretch yarn and polyester stretch yarn which are twisted; the polyurethane stretch yarn and the polyester stretch yarn are combined together under the respective draw ratios; the draw ratio of the polyurethane stretch yarn is at least two times that of the polyester stretch yarn, so that the extensibility of the polyurethane stretch yarn is limited by the polyester stretch yarn when the stretch yarn is in a tensioned state; the external wrapping layer is natural chopped fibers; and the external wrapping layer surrounds and obviously covers the whole length of the yarn core when the stretch yarn is in the tensioned state and a relaxed state. The elastic resilience can be improved, and the elasticity losing phenomenon due to water washing is reduced.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a three-core elastic yarn, a preparation method thereof, and a high-elasticity and low-shrinkage elastic silk fabric. Background technique [0002] Stretch fabric clothes, especially trousers and leggings, are comfortable and slim to wear, and have always been loved by beauty lovers. Now not only female customers, but also male customers' demand for elastic pants has skyrocketed. [0003] There are many types of fabrics for stretch pants on the market. In recent years, many manufacturers have pursued the sales of stretch fabrics and expanded their production capacity. Different technologies have led to uneven quality, some with poor air permeability, some with insufficient elasticity, and easy to deform and wrinkle after repeated washing. , and there will be shrinkage of the fabric, reducing the service life of the fabric. Contents of the invention [0004] The object of the...
