Nonwoven cloth is a material-like material made from staple fiber (short) and long fiber (steady long), bonded together by chemical, mechanical, heat or solvent deal withment. The term is used in the textile manufacturing business to denote materials, reminiscent of felt, which are neither woven nor knitted.
Totally different types of non-woven materials over-view
The non-woven materials can be divided into eight types according to totally different manufacturing processes:
Spunlace nonwovens
It is a non-woven fabric, it is the direct use of polymer slices, quick fibers or filaments right into a network of fiber by air or mechanical, spunlace, acupuncture, or scorching-rolled reinforcement, and at last after finishing the formation of spunlace nonwoven fabric.
Heat-bonded nonwoven materials
This type of non-woven material is principally manufactured in a number of processes: adding fibrous or sticky reinforcement materials into the fiber network, and then reinforcing the network into material via heating and cooling.
Pulp air-laid nonwovens
Air-laid nonwovens can be called the dustless paper or dry paper nonwovens. It makes use of the air-laid technology to open the wood pulp fiberboard into a single fiber state, then makes use of the airflow method to make the fiber agglomerate on the net curtain, and then consolidates the fiber web into cloth.
Wet-laid non-woven
The manufacturing process of wet nonwoven fabric goes like this: open the fibrous raw materials within the aqueous medium into single fibers, meanwhile forming a fibrous suspension slurry by mixing totally different fiber raw supplies, then transport the suspended slurry to a mesh-forming mechanism, and the fibers are laid in a wet state to form a cloth.
Spunbond nonwovens
Spunbond-type of nonwoven fabric is processed as follows: extrude and stretch the polymer to form a continuous filament, laid the filament into web, then process the web into nonwoven fabric by means of their own bonding, thermal bonding, chemical bonding or mechanical reinforcement methods.
Soften-blown nonwoven cloth is manufactured by extruding melted polymer fiber by means of a linear die containing several hundred small holes to form lengthy thin fibers which are stretched and cooled by passing hot air as they fall from the linear die, then the resultant web is blown onto a collector screen forming fined-filtered, self-bond nonwovens. Often, this type of nonwoven material is added to spunbond in order to form SM or SMS webs.
Acupuncture nonwovens
Acupuncture nonwoven is a type of dry nonwoven fabric. The fluffy fiber is reinforced into cloth by needle puncture.
Stitch nonwovens
Stitched nonwoven is one other type of dry nonwoven fabric. The manufacturing process uses a warp knitted loop construction to reinforce the fiber web, yarn layer, non-woven supplies (corresponding to plastic sheeting, plastic foil and etc.) or a mixture thereof in order to form a nonwoven fabric.
