Non-woven fabrics are produced by depositing extruded, spun filaments onto a collecting belt in a uniform random manner followed by bonding the fibers. The fibers are separated during the web laying process by air jets or electrostatic charges. The collecting surface is usually perforated to prevent the air stream from deflecting and carrying the fibers in an uncontrolled manner.
Non-woven products are employed in carpet backing, geotextiles, and disposable medical/hygiene products. Since the fabric production is combined with fiber production, the process is generally more economical than when using staple fiber to make non-woven fabrics
Woven, or weaving is a method by many threads or tapes woven in two directions (warp and weft), to form a fabric for plastic industry needs. In the plastic woven industry, with a plastic film is drawn into filaments, woven into fabric/sheet/cloth. It can be into a tarpaulin, woven bags, container bags, tons of bags, geotextile fabric, color of the cloth and so on.
Polypropylene, which is also known as PP for short name, is one kind of thermoplastic resin material that produced by the polymerization of propylene.
Woven polypropylene is polypropylene strips/threads that have been woven in two directions (warp and weft) to creat a light, but strong and heavy duty material.
Build with circular woven polypropylene fabric, one side sewn as the bottom, leave the other side open, the simplest woven polypropylene bags is done.
