Fabric Knowledge Introduction Of Dust-Free Fabrics

< p > simple: a href= "http://www.91se91.com/news/" > fabric > /a > is not interwoven and woven together by a single yarn. Instead, the fibers are directly bonded to each other through physical means. Therefore, when you get the sticky name in your clothes, you will find that you can not get a thread out of it.

Nonwoven fabrics break through the traditional textile principle, and have the characteristics of short process flow, fast production speed, high output, low cost, wide use, and many sources of raw materials.

< /p >

< p > its main uses can be roughly divided into: < /p >

< p > (1) medical and health care cloth: surgical gown, protective clothing, disinfectant cloth, mask, diaper, sanitary napkin and so on; < /p >

< p > (2) household decoration cloth: wall covering, table cloth, < a href= "http://www.91se91.com/news/index_c.asp" > sheets, /a > bedspreads, etc. < /p >

< p > (3) with cloth: lining, adhesive lining, floc, stereotyped cotton, all kinds of synthetic leather backing cloth; < /p >

< p > (4) industrial cloth: filter materials, insulation materials, cement packaging bags, geotextiles, coated fabrics and so on; < /p >

< p > (5) agricultural cloth: crop protection cloth, seedling raising cloth, irrigation cloth, thermal curtain, etc. < /p >

< p > (6) others: Space cotton, thermal insulation and sound insulation materials, oil absorbing felt, cigarette filter, bag, tea bag and so on.

< p > classification of non-woven fabrics: < /p >

< p > 1, Spunlaced non-woven fabric < /p >

< p > Spunlaced technology is to spray high pressure micro water into a layer or multi-layer fiber network, so that the fibers intertwine together, so that the mesh can be strengthened and has a certain strength.

< /p >

< p > two, heat bonded non-woven fabric < /p >

< p > heat bonded non-woven fabric refers to the addition of fibrous or powdered hot melt bonding material to the mesh, and the mesh is further strengthened by heating, melting and cooling.

< /p >

< p > three, pulp AIRNET, non-woven fabric < /p >

< p > air laid web non-woven fabric can also be called dust-free paper and dry papermaking non-woven fabric.

It uses air net forming technology to break the wood pulp fiber board into a single fiber state, and then uses the airflow method to make the fiber agglomerate on the net curtain, and the mesh is further reinforced into cloth.

< /p >

< p > four, wet nonwovens < /p >

< p > wet non-woven fabric is loosened into single fiber by putting raw materials into water medium, and mixed with different fiber materials to make fiber suspension slurry. Suspension slurry is pported to the mesh forming mechanism, and the fiber is reinforced into cloth under wet condition.

< /p >

< p > five, spunbonded nonwoven fabric < /p >

< p > spunbonded nonwovens are formed after the polymer has been extruded and stretched to form continuous filament. The filament is laid into a mesh, and the mesh is made of non-woven fabrics through self bonding, thermal bonding, chemical bonding or mechanical reinforcement.

< /p >

< p > six, melt blown non-woven fabric < /p >

< p > process of melt blown nonwovens: polymer feeding - melt extrusion - fiber formation - fiber cooling - mesh forming - reinforcing cloth.

< /p >

< p > seven, needle punched nonwoven fabric < /p >

< p > needle punched non-woven fabric is a kind of dry non-woven fabric. Needle punched nonwoven fabric is made by using the puncture effect of the needle, and the loose net is reinforced into cloth.

< /p >

< p > eight, stitched a href= "http://www.91se91.com" > non-woven fabric < /a > /p >

< p > stitched woven non-woven fabric is a kind of dry non-woven fabric. The stitching method is to make use of warp knitting coil structure to reinforce the mesh, yarn layer, non-woven material (such as plastic sheet, plastic thin metal foil, etc.) or their combination so as to make non-woven fabrics.
