What is a non-woven
Not because it is a fabric formed by weaving and spinning, but the textile staple fibers or filaments randomly oriented or support columns to form a fiber network structure, and mechanical, thermal or chemical methods such as reinforcement stick together. Simply say is: it is not by an a yarn woven, plaited together, but the fiber directly glued together by physical means, so when you get stuck inside your clothes when said , you will find, is a root of the thread can not spare the. Non-woven textile fabric break the traditional theory, and has a short process, production speed, high output, low cost, versatile, and more sources of raw materials and so on.
Its main purpose can be divided into:
(1) health care with a cloth: surgical gowns, protective clothing, disinfection cloth, masks, diapers, sanitary napkins, etc.;
(2) family decorative cloth: paste wall covering, table cloth, bed sheets, bedspreads, etc.;
(3) with fitted cloth: lining, interlining, flakes, stereotypes cotton, synthetic leather base cloth, etc.;
(4) Fabrics: filter material, insulation material, cement packaging bags, geotextile fabric, coated fabrics, etc.;
(5) Agricultural cloth: crop protection cloth, seedling distribution, irrigation, cloth, insulation curtain, etc.;
(6) Other: Space cotton, thermal insulation materials, linoleum smoke, smoke filter, tea bags and other bags.
Classification of non-woven fabrics:
First, spunlace non-woven
Spunlace process is the high-pressure water jet to a fine or multi-layer fiber web, the fibers tangle with each other, so that the fiber network to be reinforced and have a certain strength.
Second, the thermal non-woven
Thermally bonded non-woven fiber network is added to the fibrous reinforcement material or powder hot melt adhesive, fiber network and then cooled after melt into the fabric reinforcement.
Third, the pulp airlaid non-woven
Can be called airlaid non-woven wipes, dry non-woven paper. It is the use of airlaid pulp fiber technology will open the song into a single fiber state, and then condensed in the air way into the fiber network on the curtains, fiber network and then into the fabric reinforcement.
Fourth, non-woven wet
Is placed in water, wet non-woven fiber material in the media into a single fiber opening song, while mixing of different fiber material, made from pulp fiber suspension, transported to the pulp suspension into a network of institutions, fiber in the wet state to form a network and then reinforcement into cloth.
Fifth, spunbond
Spunbond non-woven polymer has been out in, stretching to form a continuous filament, the filament laying into the net, and then through its own fiber network bonding, thermal bonding, chemical bonding or mechanical reinforcement methods so into non-woven fiber web.
Sixth, melt-blown non-woven
Melt-blown nonwoven process: polymer melt extrusion feed --- --- --- fibers formed into a network of fiber cooling --- --- reinforcement into cloth.
Seven, non-woven needle
Dry needling non-woven fabric is a woven, non-woven fabric is the use of acupuncture needles to puncture the role of the fluffy fiber web into a fabric reinforcement.
Eight, non-woven stitch
Non-woven stitch is a dry non-woven fabrics, stitch method is the use of warp coil structure of the fiber network, yarn layer, non-textile materials (such as plastic sheets, plastic, thin metal foils, etc.) or their combination body reinforcement, made from woven to.| Updated:2011.11.15 Source: Clicks:1582
