PP Spunbond Nonwoven Fabric Production Process

Yiwu Guanghong Non-Woven Co.,Ltd | Updated: Sep 28, 2017

What is the difference between PP spinning nonwoven and nonwoven non-woven fabric

Non-woven fabric production technology of manufacturing, there are many, including spun-bonded method is a kind of non-woven fabric production process of the method of spun-bonded non-woven fabric (including spun-bonded, melt-blown, hot rolling, tap water, is now on the market most of them are using spun-bonded non-woven fabric production. Non-woven fabrics are mainly polypropylene (PP), dacron (PET), and also polyamide (PA), viscose fiber, acrylic, HDPE, PVC. Spun-bonded non-woven: spun-bonded non-woven fabric is in polymer has been after extrusion, stretching to form a continuous filament, filament laid into the net, fiber network after its adhesive, hot glue, chemical bonding or mechanical reinforcement method, make fabric non-woven fabrics.

So, this is just a basic expression problem, it is actually a kind of non-woven fabric!

The full name of pp is polypropylene, the Chinese name is polypropylene. Nw is a nonwoven abbreviation, nonwoven or nonwoven. It is the fabric that passes through the air or the machine, and then passes through the spines, needles, or hot rolled reinforcement. PPNW means non-woven fabric made of pp fibers. Due to the nature of the pp itself, the cloth has shown that the performance of the cloth is strong, but the hydrophilic ability is poor. The process of PPNW is usually spun into mesh, hot rolled and reinforced. General PPNW is used widely, packing bags, surgical protective clothing, industrial cloth and so on.

Spinning nonwovens means that S or SS produce nonwoven fabrics. The process of spinning and viscose production is different from the production process of the melting jet M, and the forming is different. S is spinning, and the spray is formed by spraying. The material is different, the process temperature is different.

Production process: the water spinner nonwovens spray the high-voltage micro-water jet into a layer or multi-layer fiber network, so that the fibers are entangled together, so that the fiber network can be strengthened and has some strength. The heat-bonded nonwoven fabric is reinforced with fibrous or powdery hot melt adhesion in the fiber net, and the fiber net is then heated to melt and harden into a cloth. Pulp airflow into a net non-woven fabric can be called clean paper, dry method paper non - woven fabrics. It is used as a network technology to loosen the wood pulp fiberboard into a single fibrous state, and then use airflow method to make the fiber to be condensed into the net curtain, the fiber net is reinforced into cloth. Wet nonwoven Opening materials in water medium fiber into single fiber, at the same time make different fiber ingredients, made from fiber suspension slurry, floating pulp suspension to the network, fiber under wet condition into a network to reinforce into cloth. Spun-bonded non-woven fabrics by the polymer has been after extrusion, stretching to form a continuous filament, filament laid into the net, fiber network after its adhesion, hot glue, chemical bonding or mechanical reinforcement method, make fabric non-woven fabrics. Melt spraying non-woven process: polymer feeding - melting extruded - fiber - fiber cooling - into mesh - reinforced fabric. A kind of spineless non-woven fabric of needling, the needling is used to use the puncture of the needle, and the shaggy fabric is reinforced into cloth. Stitch-bonded nonwoven fabric A kind of dry non-woven fabrics, sewing lawmakers is using the warp knitted coil structure on fabric, yarn layer, the textile material (such as plastic sheets, plastic thin metal foil, etc.) or their combination to reinforce, made from non-woven fabrics.
