Description

Composite straps for underwear

Technical field:

The utility model relates to a composite shoulder for underwear, which belongs to the technical field of clothing, in particular to the technical field of underwear and underwear production technology.

Background technique:

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 silicone rubber. 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. As a result, the sewing part is thicker, and it will cause an uncomfortable feeling when worn because of this thickness. Shoulder straps made of plastic and ordinary silicone rubber are not durable, have poor air permeability, and have a short service life.

Invention content:

The purpose of the utility model is to provide a composite shoulder strap with moderate thickness, soft hand feeling, breathable, beautiful appearance, proper elasticity, comfortable to wear and suitable for wearing underwear for a long time.

The purpose of this utility model is achieved in that:

A composite shoulder strap for underwear, characterized in that it includes an outer layer of chemical fiber straps, a double-sided adhesive layer and an elastic webbing; the outer layer of chemical fiber straps is wrapped on the outer surface of the elastic webbing; the adhesive layer is placed Between the inner surface of the outer chemical fiber bundle and the outer surface of the elastic webbing; the two butt edges of the outer chemical fiber bundle are seamlessly connected.

The utility model has a simple production process, and the shoulder straps produced by this process are moderate in thickness, soft to the touch, breathable, beautiful in appearance, suitable in elasticity, comfortable to wear and suitable for long-term wear, thus avoiding the continuous friction of the suture structure on the human body during the wearing process The discomfort caused by it is greatly reduced in thickness, so it is suitable for many occasions, such as evening ceremony, swimsuit, underwear, pajamas, etc., and it can also relieve the pressure on the shoulder and neck. So as to avoid causing diseases such as cervical spine strain.

Description of drawings:

Fig. 1 is the schematic cross-sectional structure diagram of the composite shoulder strap of the present utility model

Detailed ways:

Below in conjunction with accompanying drawing 1 the utility model is further described:

In order to make the shoulder strap have good elasticity, breathability, durability and other requirements, the utility model adopts a multi-layer composite structure. The shoulder strap body of the utility model includes: an outer chemical fiber bundle strip 1, a double-sided adhesive layer 2 and an elastic ribbon 3 . The outer chemical fiber bundle 1 is wrapped on the outer surface of the elastic webbing 3; the adhesive layer 2 is placed between the inner surface of the outer chemical fiber bundle 1 and the outer surface of the elastic webbing 3; the outer layer The two butt edges of the chemical fiber cloth 1 are seamlessly connected. The gist of the utility model is that the outer chemical fiber bundle 1 has only one hot-melt cutting line 11, which constitutes a structure in which the two butt joints of the outer chemical fiber bundle 1 are seamlessly connected, similar to the seam structure of a seamless steel pipe.

The outermost layer of the utility model adopts the chemical fiber binding strip, because the chemical fiber has a heat-melting property, and can utilize thermal cutting technology to realize fusion while cutting. Therefore, the use of hot-melt cutting technology makes the two butt edges of the outer chemical fiber bundle 1 fused together, similar to the structure of seamless steel pipes, although they are connected together, there will be no edges that need to be overlapped, realizing The structure of the two butt joint edges of the outer chemical fiber cloth 1 of the utility model is seamlessly connected. Therefore, the outer layer chemical fiber binding strip 1 in the utility model does not need to be stitched, and the flanging and ironing after the need for stitching in the prior art will not occur, and after the flanging and ironing, the two butt joints The joint will still produce a double layer structure, and this double layer structure will affect the wearing comfort when worn.

The use of double-sided adhesive tape to connect the elastic webbing can not only ensure the firmness of the bonding, but also ensure that the bonding has a certain degree of air permeability. The elastic webbing 3 guarantees the elasticity of the shoulder straps, and it is comfortable to wear without feeling that the shoulder straps have too much pressure. In order to complete the structure of the shoulder strap body of the present utility model, the following steps have been adopted in the process:

A: Cut the chemical fiber cloth for making the outer chemical fiber bundle 1 into a whole roll of available bundles according to the requirements;

B: Face the bundles obtained in step A face to face, and then let the bundles pass through the ultrasonic hot cutting machine, and use the ultrasonic hot cutting machine to thermally cut the butt edges of the bundles to obtain a seamlessly connected hollow outer chemical fiber bundle Article 1. The ultrasonic hot cutting machine used in the utility model is prior art, and the ultrasonic hot cutting machine sold on the general market gets final product.

C: The outer chemical fiber bundle 1 is shaped by a mesh glue laminating machine to obtain the outer chemical fiber bundle 1 with a flat structure.

D: Use the existing puller device to superimpose the double-sided adhesive tape and the elastic webbing 3 together, and then bond them together through a web glue laminating machine; a combination of the double-sided adhesive layer 2 and the elastic webbing 3 is formed;

E: The combination of the flat outer chemical fiber binding strip 1 obtained in step C and the double-sided adhesive layer 2 and elastic webbing 3 obtained in step D is pasted together by a mesh glue laminating machine; the outer layer is obtained The turned shoulder strap body is composed of the outer chemical fiber binding strip 1, the double-sided adhesive layer 2 and the elastic webbing belt 3;

F: Turn the everted shoulder strap body obtained in step E to the front using a pull hook, and obtain a composite shoulder strap for underwear. Pull hook is prior art.
