The more types of bag making equipment are used, the more diversified the range of production equipment is. The common production processes and finished products of bag making machine are as follows:
1. Spunlaced: this kind of non-woven fabric sprays high-pressure micro water onto one or more layers of fiber net to entangle the fibers together, so as to stabilize the fiber net. The obtained fabric is Spunlaced non-woven fabric.
2. Acupuncture: this kind of non-woven fabric uses the puncture effect of the needle to stabilize the fluffy fiber net into a cloth. Compared with textile fabrics, it has the advantages of high productivity, fast production speed, low price and mass production. Non woven fabrics gradually have more development advantages than textile fabrics. Because it is a kind of fabric formed by spinning and weaving without relying on the traditional process. It is formed by orienting or randomly arranging the textile short fibers to form a fiber web structure, and then stabilizing the fiber web into cloth through a needle. The needle has a hook and thorn, repeatedly puncturing the fiber web, stabilizing the hook and belt fibers, and then transmitting them to the high-temperature box for heating to form a needle punched non-woven fabric.
3. Stitching: it is a kind of dry non-woven fabric. The stitching method uses the warp knitting coil structure to stabilize the fiber web, yarn layer, non-woven materials (such as plastic sheet, plastic thin metal foil, etc.) or their combination to make non-woven fabric.
