Spunbonded non-woven fabric is formed into a continuous filament after the polymer has been extruded and stretched, and the filament is laid into a net. The net is then made into non-woven fabric through self-bonding, thermal bonding, chemical bonding or mechanical reinforcement.
Non-woven fabric is a kind of fabric that does not need to be spun and woven. Only the textile staple fiber or filament is arranged in a directional or random way to form a fabric structure, which is then reinforced by mechanical, thermal or chemical methods. Simply put: it is not interwoven and woven from one yarn to another. Instead, the fibers are glued together in a physical way, so when you get the glue in your clothes, you will find that you cannot pull out one thread after another. Nonwovens break through the traditional principles of textile, and have short technological process, production speed, high output, low cost, wide use, sources of raw materials and other characteristics.
Its main USES can be roughly divided into:
(1) medical and health cloth: surgical clothing, protective clothing, disinfectant cloth, face mask, diaper, women's sanitary napkin, etc.;
(2) household decoration cloth: wall cloth, table cloth, sheet, bed cover, etc.;
(3) heel mounting cloth: lining, bonding lining, flocculation, shaping cotton, various synthetic leather base cloth, etc.;
(4) industrial cloth: filter materials, insulation materials, cement packaging bags, geotextiles, cladding cloth, etc.;
(5) agricultural cloth: crop protection cloth, seedling raising cloth, irrigation cloth, thermal insulation curtain, etc.;
(6) others: space cotton, insulation and sound insulation materials, linoleum, cigarette filter tip, tea bag, etc.
Classification of non-woven fabrics:
1.Water spines non - woven cloth
The spiny process is a process of spraying high pressure water into a layer or multiple layers of fiber network, so that the fibers are intertwined, so that the network can be reinforced with a certain strength.
2. Hot-bonded non-woven fabrics
Thermal bonding non-woven fabric refers to the addition of fiber or powder hot melt bonding reinforcement materials in the fiber network, which is then heated to melt cooling reinforcement cloth.
3. pulp airflow into a net non - woven cloth
Airflow into a net non - woven cloth can be called dust - free paper, dry paper non - woven cloth. It is to use the air flow network technology to open up the wood pulp fiber board into a single fiber state, and then use the air flow method to agglutinate the fiber on the net curtain, the fiber network then reinforcement into the cloth.
4.Wet non - woven cloth
The wet-process non-woven fabric is to separate the fiber raw materials in the water medium into single fiber. At the same time, different fiber raw materials are mixed to make the fiber suspension slurry, which is transported to the net forming mechanism. Under the wet state, the fiber is formed into a net and then reinforced into cloth.
5.Spunbonded nonwoven fabrics
Spunbonded non-woven fabric is formed into a continuous filament after the polymer has been extruded and stretched, and the filament is laid into a net. The net is then made into non-woven fabric through self-bonding, thermal bonding, chemical bonding or mechanical reinforcement.
6.Molten spray nonwoven cloth
Melt-blown non-woven process: polymer feeding - melt extrusion - fiber formation - cooling - into a network - reinforcement into cloth.
Acupuncture non-woven cloth
7.Needling nonwoven fabric is a kind of dry nonwoven fabric. Needling nonwoven fabric is used to strengthen the fluffy net into cloth by using the puncture effect of the needle.
Eight, sewed non - woven cloth
8Stitching nonwoven fabric is a kind of dry nonwoven fabric, which is made by reinforcing the fabric, yarn layer, non-textile materials (such as plastic sheet, plastic thin metal foil, etc.) or their combination with warp coil structure to make nonwoven fabric.
