Composite shoulder strap for underwear and manufacturing method thereof

Abstract

Disclosed are an underwear composite shoulder strap and a manufacturing method thereof. The underwear composite shoulder strap comprises an elongated shoulder strap body (10) formed by two layers of fabric (1,2) joined together, wherein a silica gel sheet (20) is provided in at least part of the interior of the two layers of fabric (1,2) along the length direction of the shoulder strap body (10) and the shoulder strap body (10) bulges along the thickness direction at the position where the silica gel sheet (20) is provided. The manufacturing method comprises successively covering a bottom layer fabric (1) with and heat-sealing a first TPU adhesive film (3), a stabilizing yarn (4) and a second TPU adhesive film (5), then injecting silica gel onto the second TPU adhesive film (5) and solidifying to manufacture a silica gel sheet (20), and finally covering the silica gel sheet (20) with a thermo-compression bonded surface layer fabric (2) to obtain the underwear composite shoulder strap after cutting and shaping. Compared with the prior art, the underwear composite shoulder strap has the functions of decompression and breathability, is more comfortable to wear and durable in use.

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 silicone 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 bra (breast) to be positioned and fixed. Therefore, the shoulder strap is a main stress component of the bra product, and its comfort level when worn will have a key effect on the comfort evaluation of the entire bra product. [0003] At present, the shoulder strap products on the market are differentiated from materials, mainly webbing. In addition, a small number of shoulder strap products are made of lace material, ordinary cloth, plastic or ordinary silicone r...

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
