Description

FIELD OF THE INVENTION The present invention belongs to the technical field of composite fiber filaments, and specifically relates to elastic composite fiber filaments with UV resistance.

Composite fiber is a type of multicomponent fiber and is a term that refers to a variety of man-made fiber. Fibers in which two or more types of immiscible polymer fibers exist on the same fiber cross section are called composite fibers, which are physically modified fibers developed in the 1960s. This bicomponent fiber manufacturing technique can result in bicomponent fibers that combine the properties of two polymers. It is mainly applied to woolen yarn, blankets, woolen fabrics, heat insulating flock fillers, silk fabrics, non-woven fabrics, medical sanitary products and special work clothes.

Conventional composite fibers have low UV resistance and are inferior in long-lasting cooling sensation and water absorption and quick drying functions. There is an urgent need for suitable composite fiber filaments.

In view of the shortcomings of the prior art, the present invention provides an elastic composite fiber filament with UV resistance to solve the problems of the background art.

To achieve the above objectives, the present invention adopts the following technical solutions. The UV-resistant elastic composite fiber filament includes a first filament and a second filament, the first filament being left-handed and/or It is distributed in a right spiral,
The first filament has a core-sheath structure, and the second filament has a "8" cross section.

Furthermore, one first filament is provided, and is distributed by being wound in a left-hand spiral on the surface of the second filament.

Furthermore, one first filament is provided, and is distributed by being wound in a right-hand spiral on the surface of the second filament.

Further, two first filaments are provided, and are distributed by being wound on the surface of the second filament in a left-hand spiral and a right-hand spiral, respectively.

Further, the thickness of the first filament is 50D to 150D.

Further, the thickness of the second filament is 50D to 150D.

Furthermore, the first filament is fixed to the surface of the second filament.

Further, said second filaments are bicomponent elastic filaments comprising bicomponent polyester filaments or polyethylene filaments.

The beneficial effects of the UV-resistant elastic composite fiber filament of the present invention are as follows. The multifunctional filament of the present invention is a synthetic fiber of the first filament and the second filament, and has the functions of UV resistance, continuous cooling sensation, and water absorption and quick drying, especially for indoor and outdoor clothes in summer. The first filament and the second filament have different shrinkage, after processing the manufactured fabric, the first filament is distributed on the fabric surface and the second filament is located on the lining As a result, the shrinkage of the second filaments reduces the porosity of the entire fabric, improving the light-shielding action, and providing excellent UV resistance and heat shielding effects even with a thin fabric.

Example 1

As shown in FIGS. 1-3, the UV-resistant elastic composite fiber filament includes a first filament 11 and a second filament 22, wherein the first filament 1 is fixed to the surface of the second filament 2. ing. A single first filament 1 is provided, and is distributed by being wound on the surface of the second filament 2 in a left-hand spiral.

The thickness of the first filament 1 is 50D to 150D. The thickness of the second filament 2 is 50D to 150D. Both the first filament 1 and the second filament 2 are processed by air covering or single covering.

The first filament 1 adopts a core-sheath structure, the sheath layer is one of low melting point polyester, nylon or polyethylene, the core layer is titanium dioxide powder with a content of 5-15%, The content of titanium dioxide (0.5-3.5%) in ordinary UV-resistant outer yarns is much higher, so it has super UV-resistant and heat-shielding functions.

The second filaments 2 are bicomponent elastic filaments, including bicomponent polyester filaments or polyethylene filaments, and have a "8"-shaped cross section. During the dyeing and thermal processing of the manufactured fabric, these different components of shrinkage generate strong longitudinal stresses as well as twists off the longitudinal axis, causing the material to develop a permanent three-dimensional curl. It exhibits good elastic elongation and recovery properties to the fabric.

The first filament 1 and the second filament 2 have different shrinkage rates, and after processing the manufactured fabric, the first filament 1 is distributed on the fabric surface and the second filament 2 is located on the lining, With the shrinkage of the second filament 2, the porosity of the entire fabric is reduced, the light blocking effect is improved, and even the thin fabric has excellent UV resistance and heat shielding effects, and is durable. Enhances cooling sensation and water absorption and quick drying functions.
