Description
Technical Field
The invention relates to the technical field of household textiles, in particular to polyester fiber core-spun yarn and a preparation method thereof.
Background
With the development of society and the progress of science and technology, the requirements of people on textiles are higher and higher, and natural fibers and chemical fibers cannot meet the requirements of people. In this context, composite spinning techniques are used. Composite yarn refers to a yarn made from two or more fibers (or continuous filaments) by a composite processing technique. The composite yarn comprises blended spun yarn, blended yarn, fasciated yarn, core-spun yarn and the like.
The core-spun yarn is a novel yarn formed by combining two or more fibers. In general, a core yarn is spun from a synthetic filament having excellent tenacity and elasticity as a core yarn and a staple fiber as a sheath fiber. The core-spun yarn combines the advantages of high strength, good elasticity, uniform yarn levelness and the like of core yarn fiber and the advantages of good hygroscopicity, excellent heat retention, pilling resistance, static resistance, heat resistance and the like of outer-wrapped short fiber. At present, the core-spun yarn is widely applied to the field of home textile articles such as bedspreads, pillowcase, sofa cover, curtain, tablecloth and the like.
Core spun yarns can be divided into two broad categories, divided by the stiffness of the core filament: elastic core spun yarns and rigid core spun yarns. Elastic core yarns can be classified by the type of core yarn filament into: polyester core-spun yarn, acrylic core-spun yarn, vinylon core-spun yarn, nylon core-spun yarn and the like.
The polyester core-spun yarn usually uses polyester filament as core yarn and uses short fibers such as cotton fiber, wool, viscose fiber and the like as outer wrapping fiber. The polyester core-spun yarn has the advantages of high strength, good stiffness and smoothness, wrinkle resistance, easy washing and quick drying, good hygroscopicity, excellent antistatic property, difficult pilling, easy dyeing and finishing of the prepared textile, easy washing, good comfort and bright color.
However, the elasticity of the polyester core-spun yarn is to be further improved to further improve the wrinkle resistance, softness and comfort of the manufactured textile.
