Application of ultrasonic welding in textile industry

Application of ultrasonic welding in textile industry – Cheersonic

Textile materials suitable for ultrasonic technology

Those materials suitable for ultrasonic processing include 100% synthetic fibers, such as nylon, polyester, polypropylene, certain polyethylene, modified acrylic resins, certain vinyl compounds, urethane compounds, films, coated paper Wait. It also includes synthetic fibers mixed with 35-50% non-synthetic fiber components.

The advantages of ultrasonic application in the textile industry

1. Fast, economical and high stitching strength
2. No need to use auxiliary materials (such as: nails, glue, paper clips, etc.)
3. Ensure consistent results throughout the production process
4. No time-consuming warm-up and recovery, and no expensive cost to maintain the temperature
5. Independent cutting and stitching, no burrs
6. No pollution, avoid the use of toxic viscose and solvent
7. There are no needle holes in the seam, which can prevent the penetration of chemical agents, pathogens and tiny harmful particles

Conventional ultrasonic machining process

(1) Ultrasonic heat sealing or “sewing”:

This process can be used to form continuous seams, such as the production of protective clothing, blinds, etc., or to process immersion welding similar to buttonholes, collar stays, ties, etc. Single-machine “sewing” equipment or standard ultrasonic welding machine can realize this process.

(2) Rotary drum welding and lamination:
Nico pioneered the application of ultrasonic rotating drums to the bonding and lamination process of multiple wide mesh woven or non-woven synthetic fiber materials. The process is to pass multiple layers of fiber materials in a rotating printing cylinder and a row of welding heads to form a network pattern of sufficient width. This method does not require any chemical adhesives and other auxiliary materials to be processed into unique fabrics that other bonding methods cannot achieve. Bed covers, mattresses, disposable medical supplies, etc. can all be processed in this way.

(3) Ultrasonic cutting:
Compared with other methods, ultrasonic cutting can form smooth, long-lasting, neat edges, and will not cause discoloration of the fabric. Ultrasonic can cut and seam at the same time, which prevents the knitted or textile materials from forming thread off. At the same time, the seam has a taper to avoid pilling. Applications of ultrasonic cutting include cutting carpets, strips, clothing labels, curtains, diagonal cuts and industrial woven tapes.
