Description

A new type of aramid shoelace

technical field

The utility model relates to the technical field of webbing, in particular to a novel aramid shoelace.

Background technique

Ribbon is made of various yarns as narrow fabrics or tubular fabrics. There are many kinds of fabrics, which are widely used in clothing, shoe materials, luggage, industry, agriculture, military supplies, transportation and other industrial sectors. In the 1930s, webbing was produced in hand-made workshops. After the founding of New China, the raw materials for webbing gradually developed to nylon, vinylon, polyester, polypropylene, spandex, viscose, etc., forming three major categories of technology: weaving, knitting, and knitting. The fabric structure There are plain weave, twill weave, satin weave, jacquard, double-layer, multi-layer, tubular and joint weave, mainly woven belt and knitted belt. Ribbon, especially jacquard ribbon, is somewhat similar to the cloth label process, but the warp yarn of the cloth label is fixed, and the pattern is expressed by the weft yarn; while the basic weft yarn of the ribbon is fixed, and the pattern is expressed by the warp yarn, using a small machine. Both threading and adjusting the machine can take a long time and are relatively inefficient. But a wide variety of dazzling products can be produced, and they don't always have the same faces like cloth labels. The main function of the webbing is decorative, and some are functional. Such as popular mobile phone straps and so on. After the tape is woven, various characters can also be screen printed, which is generally cheaper than directly weaving the characters and patterns. At present, many shoelaces use webbing, but now many shoelaces will cause pilling on the surface after a long time of use, which is very inconvenient when wearing shoelaces, and the service life of cotton shoelaces is also very limited, so the design A new type of aramid shoelace was developed.

Utility model content

In view of the above problems, the utility model provides a new type of aramid shoelace. By using the aramid fiber material, the shoelace will not pilling after a long time of use, so that the surface of the shoelace is kept smooth and clean, greatly The service life of the shoelace is improved, the trouble of being difficult to wear the shoelace after the shoelace is damaged is avoided, the strength and elasticity of the shoelace are increased, and it is worth popularizing.

In order to achieve the above object, the utility model provides the following technical solutions: a novel aramid shoelace, which includes an aramid braided outer layer and an elastic fiber inner layer, the elastic fiber inner layer is arranged inside the aramid braided outer layer, the The elastic fiber inner layer is provided with a Y-shaped fiber single thread and an H-shaped fiber single thread, and a nylon fiber braided layer is arranged outside the elastic fiber inner layer, and a reinforced protective layer is arranged outside the nylon fiber braided layer. The protective layer includes a flame-retardant fiber layer, and a silicon carbide fiber reinforced layer is arranged outside the flame-resistant fiber layer, and a polytetrafluoroethylene heat-insulating layer is arranged outside the silicon carbide fiber reinforced layer.

As a preferred technical solution of the present invention, rubber particles are arranged inside the aramid braided outer layer, and antibacterial silver ions are arranged inside the rubber particles.

As a preferred technical solution of the utility model, air-permeable micropores are arranged in the elastic fiber inner layer.

As a preferred technical solution of the present invention, a polylactic acid fiber layer is arranged outside the reinforced protective layer.

Compared with the prior art, the beneficial effects of the utility model are:

The utility model uses the aramid fiber material, so that the shoelaces will not pill after long-term use, so that the surface of the shoelaces is kept smooth and clean, greatly improving the service life of the shoelaces, and avoiding the damage of the shoelaces It is difficult to wear shoelaces, and it increases the strength and elasticity of shoelaces, which is worth promoting.
