Application of ultrasonic plastic welding technology in textile industry
For many customers in the textile industry, ultrasonic energy is an important tool for forming and processing fabric and film materials. One of the most significant changes that ultrasound has brought to the textile industry is the use of "seamless" ultrasonic stitching technology to replace traditional sewing methods.
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.
Advantages of ultrasonic application in 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 adhesives and solvents
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
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. Stand-alone "sewing" equipment or standard ultrasonic welding machines can achieve this process.
Drum welding, lamination
Branson has pioneered the bonding and lamination process of multiple wide mesh woven or non-woven synthetic fiber materials using ultrasonic rotating drums. 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
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.
