Combined underwear shoulder strap and production method thereof

Abstract

The invention provides a combined underwear shoulder strap. The combined underwear shoulder strap comprises a strip-shaped shoulder strap body which is formed by laminating two layers of cloth, silica gel sheets are arranged inside at least one part of two layers of cloth of the shoulder strap body along the self length direction, and positions of the silica gel sheets on the shoulder strap body are bulged along the thickness direction. The invention further provides a production method of the combined underwear shoulder strap. The production method comprises the steps: sequentially covering and heat-sealing a first TPU (Thermoplastic Polyurethane) glue film, stabilized yarns and a second TPU glue film on a piece of bottom-layer cloth, then gluing the second TPU glue film and curing to produce silica gel sheets, finally performing hot-press gluing on the surface-layer cloth to cover the silica gel sheets, and cutting and forming to obtain the combined underwear shoulder strap. Compared with the prior art, the combined underwear shoulder strap has pressure reduction and breathability functions, and is more comfortable to wear, and durable.

Description

technical field [0001] The invention relates to a shoulder strap of an underwear bra and a manufacturing method thereof, in particular to an underwear composite shoulder strap embedded with a silica gel sheet and a manufacturing method thereof. Background technique [0002] The shoulder strap is an important part of the underwear bra. After the bra is worn, it mainly plays an important role in lifting the cup (breast). At the same time, from the structural analysis of the bra, it also plays an auxiliary role in helping the positioning and fixing of the bra (breast). Therefore, as a main stress-bearing part of a bra product, the comfort level of the shoulder strap when worn will have a key influence on the comfort evaluation of the whole bra product. [0003] At present, the shoulder strap products on the market are distinguished by materials, mainly webbing, and a small number of shoulder strap products are made of lace material, ordinary cloth, plastic or ordinary silicone...

AI Technical Summary

Problems solved by technology

Webbing is still the traditional material of choice for most shoulder straps due to its ease of manufacture, good elasticity and durability. However, the webbing material also has the problems of hard surface touch, poor hand feeling, general air permeability, and poor wearing comfort.

The lace fabric has good air permeability, but its durability is not good and it is easy to tear

Although plastic and silicone rubber shoulder straps are better in terms of durability and touch, they also have the problem of poor air permeability

[0004] In addition, the width of the general shoulder straps on the market is 10-12mm wide, and the elasticity is often greater than the pressure that human skin can bear, which will increase the pressure on the shoulder and neck. Wearing thin and tight shoulder straps for a long time in life belt, the shoulders will produce obvious strangle marks, especially for women with plump upper circumference, and even cause cervical spine strain and other diseases
