Description

Filament yarn for drawstring

Technical Field

The utility model relates to the field of nylon drawstrings, in particular to a filament yarn for a drawstring.

Background

Currently, chinese patent No.: CN204644518U discloses a polyester filament yarn, including a polyester filament yarn body, be equipped with the cotton layer on the polyester filament yarn body, the cotton layer is in by evenly distributed a plurality of fine hairs on the polyester filament yarn body constitute, the polyester filament yarn body is the silk bundle that many monofilaments constitute, the cotton layer by the polyester make and with the polyester filament yarn body sets up as an organic whole. According to the polyester filament yarn, the cotton yarn layer is arranged on the polyester filament yarn body, and the polyester filament yarn body and the cotton yarn layer are integrally arranged and are both made of polyester, so that the polyester filament yarn has the hand feeling and the moisture absorption characteristics similar to polyester staple fiber yarn or natural cotton yarn, and even the moisture absorption performance of the polyester filament yarn is superior to that of natural cotton or viscose and other fibers; if the polyester filament is changed into weaving, the cloth surface has the hand feeling of the sanded cloth without adding a sanding process. However, the prior art still has the problems of lower strength, breakage of the containing strips when the containing strips are used for drawing the strips and shorter service life in the actual use process.

SUMMERY OF THE UTILITY MODEL

Therefore, aiming at the problems, the utility model provides a filament yarn for a drawstring, which solves the technical problems that the prior art has lower strength, the containing channel is broken when the filament yarn is used for the drawstring and the service life is shorter in the actual use process.

In order to achieve the purpose, the utility model adopts the following technical scheme: the long silk thread for the drawstring structurally comprises a silk thread main body and a shaping layer, wherein the silk thread main body is of structures such as long fibers, short fibers, polypropylene filaments, low and medium polyester filaments, polyamide monofilaments and short fibers, the shaping layer is arranged on the surface of the silk thread main body, a plurality of silk thread main bodies are twisted together, and the thickness of the silk thread main body is 100-1000 dtex.

Furthermore, a single strand core or a plurality of strand cores are arranged inside the twisting structure of the silk thread main bodies.

Further, the twist of the twisting structure of the plurality of the thread main bodies is 0 to 500.

Further, the shaping layer is of a film-shaped structure compounded by glue.

Further, the thickness of the sizing layer is 0.01-0.5mm, and the sizing layer is of a single-layer structure or a composite film structure formed by compounding multiple layers of glue with different properties.

Further, the multilayer composite film structure of stereotyping layer is including locating the wearing layer that is used for improving silk thread wear resistance on the top layer and locating inside the enhancement layer that is used for gaining in strength and stereotyping.

Further, the silk thread main body of the terylene or the polypropylene fiber is mixed and twisted with the thermal fuse, the thermal fuse is arranged inside the silk thread main body or outside the silk thread main body, and the number ratio of the silk thread main body to the thermal fuse is 0.1-1.

By adopting the technical scheme, the utility model has the beneficial effects that: the filament yarn for the drawstring improves the conditions that the prior art still has lower strength, fracture of the holding strip when the filament yarn is used for the drawstring and lower service life in the actual use process, and can effectively improve the strength and the wear resistance of the filament yarn for the drawstring and effectively improve the service life and the elasticity of the manufactured drawstring by arranging the shaping layer; furthermore, the structure of the thermal fuse mixed twisting is arranged, so that the strength and the shaping performance of the silk thread can be further improved.

Drawings

FIG. 1 is a schematic structural view of a filament of the present invention;

fig. 2 is a schematic cross-sectional structure of the filament of the present invention.

In the figure: 1. a main body of the thread; 2. a shaping layer; 3. a strand core.

Detailed Description

The utility model will now be further described with reference to the accompanying drawings and detailed description.

Referring to fig. 1-2, the present embodiment provides a long filament for a drawstring, which includes a filament main body and a sizing layer, where the filament main body is made of long fibers, short fibers, polypropylene filaments, low and medium polyester filaments, polyamide monofilaments, short fibers, and the like, the sizing layer is disposed on the surface of the filament main body, a plurality of the filament main bodies are twisted together, and the thickness of the filament main body is 100 dtex and 1000 dtex.

And a single strand core or a plurality of strand cores are arranged in the twisting structure of the silk thread main bodies.

The twist of the twisting structure of the silk thread main bodies is 0-500.

The shaping layer is of a film-shaped structure compounded by glue.

The thickness of the shaping layer is 0.01-0.5mm, and the shaping layer is of a single-layer structure or a composite film structure formed by compounding multiple layers of glue with different properties.

The multilayer composite film structure of the shaping layer comprises a wear-resistant layer arranged on the surface layer and used for improving the wear-resistant performance of the silk thread and a reinforcing layer arranged inside and used for increasing strength and shaping.

The polyester or polypropylene fiber silk yarn main body is mixed and twisted with the hot melt yarns, the hot melt yarns are arranged inside the silk yarn main body or outside the silk yarn main body, and the number ratio of the silk yarn main body to the hot melt yarns is 0.1-1.

This embodiment provides a by this stretching strap made of filament yarn for stretching strap simultaneously, and many stretching straps are set up with filament yarn side by side to with its one end with high frequency with this stretching strap with filament yarn clamp in the middle of two PVC, the same setting is done to the other end.
