Problems solved by technology

[0003] Chinese patent 03113412.2 discloses a method for preparing polyester sewing thread. The polyester sewing thread obtained by this method is a single thread, and its strength and various properties are far from meeting the requirements
[0004] Chinese patent 93119637x discloses a sewing thread. The sewing thread of this patent is coated with an outer layer on the outside of the thread, which limits its scope of application.
[0006] However, the current polyester core-spun sewing thread often brings problems such as poor covering surface and hairy yarn during the spinning process.

Embodiment 1

[0036] Preparation of high-strength sewing thread T61 / T3913.1tex×2, 45s2 strands of polyester filament wrapped with polyester staple fiber:

[0037] The raw polyester staple fiber is passed through the steps of cleaning, carding, drawing, roving, spun yarn, automatic winding, doubling, and double twisting, and then the polyester filament and polyester staple fiber strands are combined and spun on the spinning frame. system to obtain said polyester corespun sewing thread.

[0038] The spinning steps are as follows:

[0039] 1. The ratio is as follows (weight):

[0040] Polyester staple fiber 39%, fineness 1.33dtex, length 38mm, provided by Toray Corporation of Japan.

[0041] Polyester filament 61%, fineness 78dtex F30 provided by Qingdao Zhongtai Company (spun from the spinning step).

Abstract

The invention discloses a polyester wrapped core sewing thread and a preparation method thereof. The composition and weight percentage comprises 30-45 percent of polyester staple fiber, 55-70 percent of polyester filament. By steps of scutching, carding, drawing, roving, spinning, auto winding, doubling and double twisting, the raw material polyester staple fiber is combined and spun by a spinning machine roving. The polyester wrapped core sewing thread provided by the invention obviously improves the strength of the wrapped core thread, decreases the unevenness of the strength, reduces hairs, for the reasons of controlling the speed and adjusting the gauge between main processes, the fixed quantity, the twist factor of spinning and double twisting as well as the temperature and humidity control range, thus leading the wrapped core thread to meet the requirements of high speed sewing. The polyester wrapped core sewing thread spun by the method of the invention has the advantages of high strength, low strength unevenness, good evenness, well-covered surface, better elastic modulus, heat insulation, air permeability and adhesive property, etc.

Description

technical field [0001] The invention relates to a sewing thread and a preparation method thereof, in particular to a core-spun yarn and a preparation method thereof. technical background [0002] With the development of the garment industry and the need for high-speed sewing, the requirements for sewing threads are getting higher and higher. Traditional polyester sewing threads can no longer keep up with the needs of high-speed sewing development. High-strength sewing threads and their high-speed state will not melt The requirements for sewing thread are also mentioned on the agenda of textile engineering. [0003] Chinese patent 03113412.2 discloses a preparation method of polyester sewing thread. The polyester sewing thread obtained by the method is a single thread, and its strength and various properties are far from meeting the requirements. [0004] Chinese patent 93119637x discloses a kind of sewing thread, and the sewing thread of this patent is coated with one deck ...
