Hot adhesion method

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.

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.

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 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 method

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

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.


Slurry air flow mesh forming method

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.
