The traditional yarn coated with the nylon has the defects of insufficient strength, too large elongation and poor dimensional stability, and finished products manufactured by the nylon, such as outdoor sunshade, hurricane-resistant sunshade, awning, etc., are easy to deform and elongate when used for a long time, and have short service life, and the traditional yarn manufactured by the aramid fiber has the advantages of high strength, sensitivity to ultraviolet rays, obvious illumination discoloration problem, loss of strength when being exposed to ultraviolet rays for a long time, and limited use area because the finished product of the aramid fiber is exposed outdoors for a long time and is easy to change color and lose strength after being irradiated by ultraviolet rays.

Disclosure of utility model

The present utility model is directed to a high strength yarn to solve the above-mentioned problems.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a high strength yarn, includes the parcel layer, the inside fixed aramid fiber sandwich layer that has inserted of parcel layer, the parcel layer parcel in the outside of aramid fiber sandwich layer, the inside wall of parcel layer with the outside wall laminating of aramid fiber sandwich layer.

Preferably, the wrapping layer comprises a polyvinyl chloride wrapping layer.

Preferably, the wrapping layer includes a thermoplastic polyurethane elastomer wrapping layer, and the thermoplastic polyurethane elastomer wrapping layer is fixedly sleeved on the outer side of the aramid fiber core layer.

Preferably, the core diameter of the aramid fiber core layer is 0.3mm-1mm.

Preferably, the fineness of the core of the aramid fiber core layer is 300D-3000D.

Compared with the prior art, the utility model has the beneficial effects that:

When the ultraviolet light irradiation type color change yarn is used, the wrapping layer on the outer side of the aramid fiber core layer plays a role in protecting the aramid fiber core layer, the service life of the aramid fiber is prolonged, the aramid fiber core layer is exposed to ultraviolet rays for a long time, color change and strength loss are easy to occur, and the wrapping layer is arranged on the outer side of the aramid fiber core layer, so that the aramid fiber core layer is effectively protected, the aramid fiber core layer is prevented from being contacted with the ultraviolet rays, the problems of light irradiation color change and strength loss can be effectively solved, the ultraviolet light irradiation type color change yarn is not easy to deform, the elongation is low, the aramid fiber irradiation type color change yarn can be used indoors and outdoors, the region restriction is avoided, and the service life of the yarn is prolonged.
