A nonwoven fabric is a fabric made from short fibers and long fibers (long without breakage), linked together by chemical, mechanical, thermal treatment or the use of solvents. The term is used in the textile industry to refer to fabrics such as felt, non-woven or non-knitted fabrics.
Nonwoven fabrics can be divided into 8 types according to different production processes:
Spunlace Nonwoven Fabric
This is a product created from the direct use of polymer pieces, short fibers or filaments form a fiber network thanks to the action of gas or mechanics, spinning process, needle piercing or hot rolling, and the final stitch after completion is spunlace nonwoven.
Application: This fabric is famous for its great uses as masks, medical nonwoven fabrics, wet wipes, non-woven filter cloths, etc.
Heat-linked nonwoven fabric
This nonwoven fabric is mainly produced in several processes: adding a fibrous filler material or sticking to the fiber network, and then reinforcing the network into the fabric through heating and cooling.
Pulp airlaid nonwoven fabric
Pulp airlaid nonwoven fabric is also known as dust-free paper, dry nonwoven fabric. It uses air-laid technology to open the wood fiber board into a single fiber state, then uses the air flow method to agglomerate the fibers on the mesh screen and the reinforced fiber mesh forms the fabric.
Wet nonwoven fabric
Wet nonwoven fabric is produced according to the following process: open a fiber material placed in the aqueous medium into single fibers, and simultaneously mix different fiber materials to form a fiber mixture, after which this mixture is transferred to the membrane making mechanism, and the yarn in the wet state is reinforced into the fabric.
Spunbond nonwoven fabric:
Spunbond nonwoven fabric is produced according to the following process: extrusion and stretching of polymer fibers to form continuous fibers and mesh formations. This mesh is then processed into a nonwoven fabric thanks to the method of adhesive, thermal bonding, mechanics and chemical bonding.
Meltblown Nonwoven Products
Melblown nonwoven fabric is produced by extruding molten polymer fibers through a straight mold containing hundreds of small holes to form long thin fibers that are then stretched and cooled by letting hot air pass through as they fall from the straight mold, then this mesh is blown into a centralized screen forming self-bonding nonwoven fabric and finely filtered. Typically, this nonwoven fabric is added to the spunbond yarn to form an SM or SMS mesh.
Non-knitted fabric is a dry nonwoven fabric. Fine threads are reinforced into fabric by piercing needles.
Stitch nonwoven fabric
Stitched nonwoven fabric is another type of dry nonwoven fabric. The manufacturing process uses a vertical knitted yarn ring structure to reinforce yarn mesh, yarn layers, nonwoven materials (such as plastic sheets, plastic foils, etc.) or their combinations to form nonwoven fabrics.
Nonwoven Fabric Market: The nonwoven fabric market size is estimated to grow from USD 22.62 billion in 2016 to USD 34.85 billion by 2022. This market is expected to grow at a CAGR of 7.51% during the forecast period. The base research year is 2016, and the market size is estimated from 2017 to 2022.
