Welding process (Welding)

The fusion process is a new process technology that uses the heat generated by ultrasonic waves to bond two layers of fabric. The welding process is mainly produced by the device passing through a tentacles that continuously vibrate in the upper part of the two-layer fabric, and the bottom passes through a uniformly rotating drum wheel. The drum wheel pushes up the fabric to be bonded, and when the tentacles touch the fabric that is pushed up, the friction generated by the combination of pressure and heat acts to bond and shear the fabric.

Different from the above bonding process, the welding process requires high processing of the fabric, and the fabric must have at least 60% thermoplasticity.

The welding process is mainly divided into two forms: one is partial welding and the other is quilting welding. The partial welding can bond the two fabrics in any designed shape, which is mainly realized by a mold form, and the mold shape can be arbitrarily designed. The splicing trajectory formed by the quilting fusion is continuous and is suitable for fixing the hem. Each hem or trim of the quilted weld can be designed with different drums and antennae to form different welding trajectories, and the fusion and cutting points can be between 1 and 10 mm.

There are two main types of welding processes: one is bonding and the other is cutting.

The local welding process can be used for the manufacture of disposable products such as disposable paper and non-woven products for household use, as well as for the production of women's underwear and toys; quilted fusion contact can be used for disposable medical clothes. In addition to the production of clothing and women's underwear, it can also take advantage of its cutting function in the production of lace and tablecloth.

Molding process (moulding)

The mold forming process is the latest process of pressing the fabric into a pre-made mechanical mold and pressing it at a certain temperature.

At present, the mold forming process is mainly used for the production of female bras. Because female bras require multiple layers of fabric to increase the thickness of the undergarment product, it is more suitable for processing by compression molding. The molded bra has no sew marks, and the surface and inner lining are extremely smooth. Compared with the traditional bra, the comfort is greatly improved.

Rapid Prototyping

Similar to the mold forming process, the rapid press forming process is also a process of forming a processed material through a mold. The difference between the rapid press forming process and the mold forming process is that during the molding process of the mold, the material retains its original physical properties and is molded at a high temperature under a certain temperature condition.

In the process of rapid press forming, the material is in a molten state and solidified and formed in a short time. It has special requirements on the material - it must be a new material in the field of fiber fabrics, so the rapid press forming technology for future garments The influence of the industry needs to be achieved through cooperation with the textile industry.

At present, the rapid press forming process is mainly used for the production of functional sportswear accessories such as skates, roller skates, protective helmets and the like.

With the continuous optimization and innovation of science and technology, more advanced sewing technology will be scientifically and reasonably connected with sewing machinery, and fully utilized in garment production, which will further enhance the functionality and comfort of human clothing. Important role. Therefore, we have reason to believe that the future of the world's clothing industry and sewing machinery industry will be even better.
