What is a non-woven fabric
2015-03-23
Non-woven fabric which does not require the formation of spinning and weaving, but the textile staple fibers or filaments oriented or random support columns to form a fiber network structure, and then use mechanical, thermal or chemical methods such as reinforcement stick together . Simply say is this: it is not interwoven by a single yarn, knitting together, but the fibers are directly bonded together by physical methods, so when you get a sticky clothes when you say , you will find a spare one thread of the root. Nonwovens breaking the traditional textile principle, and has a short process, production speed, high output, low cost, versatile, sources of raw materials and more features.
Its main purpose can be divided into:
(1) Health cloth: surgical clothing, protective clothing, disinfectant cloth, masks, diapers, sanitary napkins, etc;
(2) household decorative cloth: stick wall coverings, tablecloths, sheets, bedspreads, etc;
(3) with fitted cloth: lining, interlining, flakes, stereotypes cotton, a variety of synthetic leather base cloth, etc;
(4) Fabrics: filtering materials, insulation materials, packing bag, geotextiles, coated fabrics and so on;
(5) with a cloth agriculture: crop protection cloth, cloth seedlings, irrigation cloth, insulation curtain, etc;
(6) Other: Space cotton, insulation materials, absorption felt, cigarette filters, tea bags and other bags package.
Nonwoven Category:
First, spunlace
Spunlace process is a high pressure water jet to a fine layer or layers of fiber web, the fibers are entangled with each other, so that the web to be reinforced and have a certain strength.
Second, non-woven heat
Thermally bonded nonwoven web is a technique of adding a fibrous reinforcing material or powdered hot melt adhesive, the web and then through the heating and melting is cooled reinforcement into cloth.
Three, airlaid pulp nonwoven fabric
Airlaid nonwoven fabrics can be called airlaid, airlaid nonwovens. It is the use of airlaid pulp fiber technology will loosen the fibers into a single state, and then the fiber agglutination method using flow on a net curtain, fiber network and then reinforcement into cloth.
Fourth, non-woven wet
Wet non-woven fabric is placed in an aqueous medium fiber material fibers into a single opening, while the different fiber raw materials are mixed, formed into a fiber pulp suspension, the pulp suspension fed to the laying means, the fibers in the wet state into the network and then reinforcement into cloth.
Fifth, spunbond
Spunbonded nonwoven fabric is in the polymer has been extruded, stretched to form a continuous filament, the filament laying into a web, the web and then through the self-adhesive, thermal bonding, chemical bonding or mechanical reinforcement method, so that become non-woven webs.
Six, meltblown nonwoven
Meltblown nonwoven process: feeding a polymer melt extruded --- --- --- fiber-forming fibers into a network of cooling --- --- reinforcement into cloth.
Seven non-woven needle
Acupuncture non-woven is a dry non-woven, non-woven fabric is the use of acupuncture needle puncture effect, fluffy fiber mesh reinforcement into cloth.
Eight non-woven stitch
The stitch-bonded nonwoven fabric is a dry nonwoven fabric, stitch bonding is the use of warp coil structure of the web, the yarn layer, a non-woven material (e.g., plastic sheets, plastic thin metal foils, etc.) or a combination thereof body reinforcement, to prepare a nonwoven fabric.
