Composite strap for underwear, production technology and specialized setting and positioning machine

Abstract

The invention provides a composite strap for underwear, a production technology and a specialized setting and positioning machine and belongs to the technical field of underwear and underwear production technologies. The composite strap for the underwear is characterized in that the composite strap for the underwear comprises outer layer chemical fiber straps, double-surface adhesive layers and elastic braids, wherein the outer layer chemical fiber straps are coated on the outer surfaces of the elastic braids, the adhesive layers are arranged between the inner surfaces of the outer layer chemical fiber straps and the outer surfaces of the elastic braids, strap materials conduct hot melting cutting on the butt joint sides of the straps through an ultrasonic hot cutting machine, so that the two butt joint sides of each outer layer chemical fiber strap are connected in a seamless mode, and the butt joint sides of each outer layer chemical fiber strap are positioned and set by the specialized setting and positioning machine and are then attached to each other through a net adhesive laminating machine. The production technology is simple, so that the produced straps are medium in thickness, soft in hand feel, breathable, attractive, appropriate in elasticity, comfortable in wearing and suitable for long-time wearing, and the uncomfortable feeling brought by the constant friction of the seaming structure to a human body during wearing is avoided.

Description

Technical field: [0001] The invention relates to a composite shoulder strap for underwear, a production process and a special setting positioner, which belong to the technical field of clothing, in particular to the technical field of underwear and underwear production technology. Background technique: [0002] Shoulder straps are an important part of underwear such as bras, shapewear, one-piece underwear, and swimsuits. They play a role in maintaining cups, preventing underwear from sagging, and keeping underwear in a predetermined position. Therefore, the shoulder strap is the main stress-bearing part of the whole underwear. The shoulder strap is in direct contact with the human body, and its quality directly affects the comfort of the underwear. At present, the existing shoulder straps on the market are mainly elastic webbing from the material point of view, and there are a small number of other shoulder strap products made of lace, ordinary fabrics, plastic or ordinary s...

AI Technical Summary

Problems solved by technology

Whether it is webbing or shoulder straps made of other materials, there are more or less problems of one kind or another, such as hard touch, poor hand feeling, poor durability, poor air permeability, etc.

Especially for the shoulder straps made by stitching, after the shoulder straps are sewn, a stitching part will be formed. Usually, after stitching, the seamed edge will be turned over and then ironed flat, so that the stitching part will become a double-layer structure. This results in a thicker seam, which can cause an uncomfortable feeling when worn

Shoulder straps made of plastic and ordinary silicone rubber are not durable, have poor air permeability, and have a short service life
