Non-woven Textile Ultrasonic Process

Textile materials suitable for ultrasonic welding:

Materials suitable for ultrasonic processing include 100% synthetic fibers such as nylon, polyester, polypropylene, certain polyethylene, modified acrylics, certain vinyl compounds, carbamate compounds, thin films, coated paper, etc. It also includes synthetic fibers that are 35-50% non-synthetic.

Advantages of ultrasonic application in textile industry:

1, fast, economical, high suture strength

2, without the use of auxiliary materials (such as: buckles, adhesives, paper clips, etc.)

3. Ensure consistent effect throughout the production process

4. No time to preheat and restore, and no expensive cost to maintain temperature

5, independent cutting and stitching, no burrs

6, no pollution, avoid the use of toxic adhesives and solvents

7, seam without needle eye, can prevent the infiltration of chemical agents, pathogens and small harmful particles

Conventional ultrasonic weldling processing technology:

(1) Ultrasonic thermal bonding or "sewing" :

This process can be used to form continuous joints for applications such as protective clothing, blinds, etc., or for immersion welds such as button holes, collar stays, ties, etc. Standalone "sewing" equipment or standard ultrasonic welding machine can achieve this process.

(2) Rotary drum welding and lamination:

Jiayuanda pioneered the bonding and lamination process of multiple wide mesh textile or non-textile synthetic fiber materials with ultrasonic roller. The process involves passing multiple layers of fibrous material through a rotating printing cylinder and a row of solder joints to create a network pattern of sufficient width. This method does not require any chemical adhesives and other AIDS to produce unique fabrics that cannot be achieved by other bonding methods. Bedspreads, mattresses, disposable medical supplies can be processed by this method

(3) Ultrasonic cutting:

Compared with other methods, ultrasonic cutting produces smooth, durable, neat edges without discoloration of the fabric. Ultrasound can be used to cut and sew at the same time, which prevents the knitting or textile material from falling apart. At the same time, there is a taper at the seam side to avoid pilling. Ultrasonic cutting applications include cutting carpets, strips, clothing labels, curtains, skew and industrial woven belts.
