Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to shoulder straps for brassieres, slips, etc., which are made of an elastic tape woven with elastic covered yarn as the warp.

Conventional technology The shoulder straps of women's underwear, such as brassieres and slips, are made of stretchable fabrics that are woven using synthetic fiber elastic threads such as spantex as the core thread, and elastic covered yarns with synthetic filaments wrapped around this as the warp threads. The shoulder strap is constructed by cutting the elastic tape to a required length and attaching a length adjuster and a hanging ring thereto, and the shoulder strap is stretchable over the entire length direction.

Problems that the invention aims to solve However, since such conventional shoulder straps have elasticity over the entire length, they can cause shoulder stiffness, especially when worn with bras, due to the feeling of pressure caused by the elasticity. There were problems with skin irritation and streaks on the skin.

Means for Solving the Problems This invention is intended to solve the above-mentioned problems, and the details thereof will be explained below using FIG. 1 corresponding to an embodiment. 1 is the shoulder strap, which uses a synthetic fiber elastic thread such as spantex as the core thread, uses elastic covered yarn wrapped with synthetic fiber filament as the warp thread, and uses elastic tape woven on a needle loom as the material to adjust the length. The elastic shoulder strap 1 is constructed by sewing a hanging ring 3 onto the shoulder strap 1.
An appropriate length of the portion 4 located on the shoulder when worn is point-fused by high-frequency ultrasonic irradiation.

Function The shoulder strap 1 of the present invention has a slight elasticity in the portion 4 located on the shoulder due to point welding by the processing means, and the elasticity is locally suppressed as a whole.

Embodiment FIG. 2 shows an explanatory diagram of applying high-frequency ultrasonic processing to a portion 4 located on the shoulder of the shoulder strap 1, where A is an ultrasonic oscillation form connected to a high-frequency ultrasonic oscillator B, and C is the oscillation form. and an albin fixed with an adjustable gap D, and the surface of the albin is patterned with arbitrary irregularities in order to centrally control the ultrasonic waves emitted from the ultrasonic oscillation form A. . Then, the part 4 of the shoulder strap 1 to be processed, which is located on the shoulder, is interposed in the gap and processed by ultrasonic irradiation, so that the part 4 is point-fused and locally expanded and contracted in the length direction. The purpose is to obtain a shoulder strap with suppressed sexuality.

Effects of the invention As explained above, the present invention suppresses the elasticity of the shoulder straps of women's underwear such as bras and slips, which are made of elastic tape woven with elastic covered yarn as the warp. As a result, when wearing a brassiere, the feeling of pressure caused by the elasticity is eliminated compared to conventional bras that have elasticity throughout the length, and as a result, there is no stiff shoulders or skin irritation, and it is more comfortable on the shoulder skin. It has the effect that it can be expected to be comfortable to wear without causing streaks and impairing the aesthetic appearance.
