The fibers used in the production of non-woven fabrics are mainly polypropylene (PP) and polyester (PET). In addition, there are nylon (PA), viscose fiber, acrylic fiber, polyethylene (HDPE), and polyvinyl chloride (PVC). According to the application of medicinal wine, non-woven fabrics are divided into two categories: disposable and durable.
1 Spunlaced nonwoven fabric
Spunlaced technology is to spray high-pressure micro water onto one or more layers of fiber nets, so that the fibers are intertwined with each other, so that the fiber nets can be reinforced and have a certain strength.
2 Heat sealing non-woven fabric
Heat bonded non-woven fabric refers to adding fibrous or powdery hot-melt bonding reinforcement materials to the fiber web, and then heating, melting, cooling and strengthening the fiber web into cloth.
3 Pulp air laid nonwoven fabric
Air laid nonwoven fabric can also be called dust-free paper and dry papermaking nonwoven fabric. It uses the air flow netting technology to loosen the wood pulp fiberboard into a single fiber state, and then uses the air flow method to agglutinate the fibers on the netting curtain, and then the fiber mesh is reinforced into cloth.
4 Wet non-woven fabric
Wet non-woven fabric is to loosen the fiber raw materials placed in the aqueous medium into single fibers, mix different fiber raw materials at the same time, and make fiber suspension slurry. The suspension slurry is transported to the netting mechanism, and the fibers are netted in the wet state and then reinforced into cloth.
5 Spunbonded nonwoven fabric
Spunbonded non-woven fabric is that after the polymer has been extruded and stretched to form continuous filaments, the filaments are laid into a web, and the web is then self bonded, thermally bonded, chemically bonded or mechanically reinforced to turn the web into a non-woven fabric.
6、 Melt blown nonwoven fabric
The technological process of melt blown non-woven fabric: polymer feeding --- melt extrusion --- fiber formation --- fiber cooling --- netting --- reinforcement into cloth.
7 Needled nonwoven fabric
Needled non-woven fabric is a kind of dry non-woven fabric. Needled non-woven fabric uses the puncture effect of needles to consolidate the fluffy fiber net into cloth.
8 Sewn nonwoven fabric
Sewn non-woven fabric is a kind of dry non-woven fabric. Sewn non-woven fabric uses warp knitting coil structure to reinforce fiber mesh, yarn layer, non-woven materials (such as plastic sheet, plastic thin metal foil, etc.) or their combinations to make non-woven fabric.
Nonwovens are handmade with nonwovens (the picture on the right is made with nonwovens). Now more and more manual enthusiasts have joined in Nonwovens handmade, because: 1. Nonwovens are made of special materials, which are thicker and harder than ordinary cloth, and there will be no cotton thread falling, so it is convenient to sew. 2. Things made of non-woven cloth are cute and lifelike, and gifts can express your feelings. 3. There are different colors of non-woven fabrics. You can design different patterns. Non woven books, non-woven cakes, non-woven dolls, non-woven bags... Can be made by our hands.
Medical non-woven fabric products are medical and health textiles made of chemical fibers including polyester, polyamide, polytetrafluoroethylene (PTFE), polypropylene, carbon fiber and glass fiber. It includes disposable masks, protective clothing, surgical clothes, isolation clothes, experimental clothes, nurse hats, surgical hats, doctor hats, surgical bags, maternity bags, first aid kits, diapers, pillowcases, bedsheets, quilt covers, shoe covers and other disposable medical consumables. Compared with traditional cotton woven medical textiles, medical nonwovens have the characteristics of high filtration of bacteria and dust, low surgical infection rate, convenient disinfection and sterilization, and easy compounding with other materials. As disposable products, medical nonwovens are not only convenient to use, safe and hygienic, but also can effectively prevent bacterial infection and iatrogenic cross infection. In China, the investment in the medical and health industry has reached more than 100 billion yuan in recent years, of which the total output value of sanitary products and materials has reached about 64 billion yuan, and is developing in the direction of diversification.
Flour bags made of non-woven fabrics have the characteristics of light weight, environmental protection, moisture-proof, breathable, flexible, flame-retardant, non-toxic, non irritating, recyclable and so on. They are internationally recognized environmental protection products that protect the earth's ecology. They are widely used in all kinds of small packages of rice noodles, such as wheat flour, corn flour, buckwheat flour Rice, etc. This kind of non-woven fabric products are printed with ink, which is beautiful, lifelike, non-toxic, tasteless and non-volatile. It is more environmentally friendly and clean than ink printing, and fully meets the environmental protection requirements of modern people. Due to its reliable quality, affordable price and long service life. The main specifications include 1 kg, 2.5 kg, 5 kg, 10 kg rice flour hardcover bags, packaging bags, etc.
Nonwoven bags (also known as nonwoven bags, English: nonwoven bags) is a kind of green products, tough and durable, beautiful shape, good permeability, reusable, washable, silk screen advertising, shipping marks, long service life, suitable for any company, any industry as advertising, gifts. While shopping, consumers get a beautiful non-woven bag, while businesses get invisible advertising, the best of both worlds, so non-woven fabrics are becoming more and more popular in the market.
