Detailed explanation of non-woven process classification with pictures and texts

What is non-woven fabric?

Also known as: non-woven fabric, non-woven fabric

English: NONWOVEN FABRIC

No Weaving No Waving

No Knitting

No Yarn

Use fibers or chips

Variety bonding of fibers

The fibers used in the production of non-woven fabrics are mainly polypropylene (PP) and polyester (PET). In addition, there are nylon (PA), viscose, acrylic, ethylene (HDPE), and vinyl (PVC). According to the application requirements, non-woven fabrics are divided into two categories: disposable application type and durable type.

Non-woven fabrics are mainly made of polypropylene (PP) and polyester (PET). In addition, there are nylon (PA), viscose fiber, acrylic fiber, polyethylene (HDPE), polyvinyl chloride (PVC). According to the application requirements , non-woven fabrics can be divided into two categories: one-time application type and durable type. Non-woven fabrics 

are non-woven fabrics that directly use high polymer chips, short fibers or filaments to pass fibers through airflow or Machine-laid, then spunlaced, needle-punched, or hot-rolled for reinforcement, and finally finished to form a non-woven fabric.

Nonwoven fabric is a kind of nonwoven fabric, which is a non woven fabric formed by directly using high polymer chips, short fibers or filaments to form a net of fibers through air flow or mechanical network, and then through water pricking, acupuncture, or hot rolling reinforcement, and finally finishing.

According to the production process, it can be divided into :

thermal bonding

The thermal bonding process is divided into hot rolling and hot air. It refers to the addition of fibrous or powdery hot-melt adhesive reinforcement materials to the fiber web, and the fiber web is then heated, melted, cooled, and consolidated into a cloth.

Thermal bonded process is divided into hot rolling and hot air. It refers to adding fibrous or powdery hot-melt bonded reinforcing materials into the web, which is then strengthened by heating, melting and cooling.

Hot air non-woven fabric is a kind of hot air bonded (hot rolling, hot air) non-woven fabric. Bond the resulting non-woven fabric.

Hot air non-woven fabric is one of the hot-air bonded (hot-rolled, hot-air) non-woven fabrics. Hot air non-woven fabric is a kind of non-woven fabric that is formed by carding the fibers and then heating the fibers by using the hot air on the drying equipment to penetrate the fiber web.

Acupuncture

Acupuncture is a kind of dry-laid non-woven fabric, which uses the puncturing action of a needle to reinforce the fluffy fiber web into a cloth.

Needle-punched technic is a kind of dry nonwovens. it use the puncture function of needles to reinforce the fluffy fibre web into cloth

Spunlace

The spunlace process is to spray high-pressure fine water flow onto one or more layers of fiber webs, so that the fibers are entangled with each other, so that the fiber webs are reinforced and have a certain strength.

Spunlaced non-woven fabrics : Spunlaced process is to spray high-pressure micro-water into one or more layers of fiber mesh, so that the fibers intertwined, so that the fiber mesh can be strengthened and have a certain strength.

Pulp airlaid method

Pulp air-laid non-woven fabrics refer to air-laid non-woven fabrics, which can also be called dust-free paper and dry-laid non-woven fabrics. It uses the air-laid technology to open the wood pulp fiberboard into a single fiber state, and then uses the air-laid method to condense the fibers on the web-forming curtain, and the fiber web is then reinforced into a cloth.

Pulp air-laid non-woven fabrics, also called dust-free paper, dry paper-making non-woven fabrics. It uses air-flow netting technology to loosen the wood pulp fiberboard into a single fiber state, and then uses air-flow method to agglomerate the fibers on the screen curtain, and then reinforce the fibernet into cloth.
