Non-woven bag production process

Fujian Plastic Industry Co., Ltd. is a professional wholesaler of non-woven bags. Non-woven fabrics are non-polluting materials. How is it produced? Next, let's take a closer look. Non-woven fabric production process, non-woven fabric production fibers are mainly polypropylene (PP) and polyester (PET). In addition, there are nylon (PA), viscose, acrylic, polyethylene (HDPE), and chlorinated fiber (PVC). According to application requirements, non-woven fabrics are divided into two categories: disposable application type and durable type. According to the production process, it is divided into: 1. Spunlace non-woven fabric: The spunlace process is to spray high-pressure fine water onto one or more layers of fiber webs to entangle the fibers with each other, so that the web can be reinforced and have a certain strength 2. Thermally bonded non-woven fabric: Thermally bonded non-woven fabric refers to the addition of fibrous or powdery hot-melt adhesive reinforcement materials to the fiber web, and the fiber web is heated, melted and cooled to form a cloth; 3. Pulp air flow Net non-woven fabric: Air-laid non-woven fabric can also be called dust-free paper and dry paper-making non-woven fabric. It uses air-laid technology to open the wood pulp fiberboard into a single fiber state, and then use the air-flow method to agglomerate the fibers on the web curtain, and then reinforce the fiber web into a cloth; 4. Wet non-woven fabric: wet non-woven The cloth is to open the fiber raw materials placed in the water medium into single fibers, and at the same time mix different fiber raw materials to make a fiber suspension slurry, which is transported to the web forming mechanism, and the fibers are formed into a web in a wet state and then reinforced into a cloth; 5. Spunbond non-woven fabric: Spunbond non-woven fabric is formed after the polymer has been extruded and stretched to form continuous filaments, the filaments are laid into a web, and the web is then bonded by itself, thermally bonded, and chemically. Bonding or mechanical reinforcement method to make the fiber web into a non-woven fabric; 6. Melt-blown non-woven fabric: The process of melt-blown non-woven fabric: polymer feeding---melt extrusion---fiber formation-- -Fiber cooling---net formation---reinforcement into fabric; 7. Needle-punched non-woven fabric: Needle-punched non-woven fabric is a kind of dry-laid non-woven fabric, and needle-punched non-woven fabric uses the piercing effect of needles. Reinforce the fluffy fiber web into a cloth; 8. Stitched non-woven fabric: Stitched non-woven fabric is a kind of dry-laid non-woven fabric. The stitching method uses warp-knitted loop structure to affect the fiber web, yarn layer and non-woven fabric. Textile materials (such as plastic sheets, plastic thin metal foils, etc.) or their combinations are reinforced to make non-woven fabrics; the above is a non-woven bag wholesaler who introduces the production process of non-woven fabrics. help.
