non woven flap wheel  production, thermal bonding with acupuncture, spunlace, spunbond, meltblown, like the more common applications process, the essence of this process is the use of heat to bond reinforcement webs. Due process in low energy consumption, less pollution, thermal bonding is also a low carbon nonwoven processes.
Most of thermoplastic polymer materials, which will be heated to a certain temperature softened and melted into a certain viscosity of the fluid flow, cooling and then re-solidified into a solid. A thermal bonding process by heating, deformation, melting, flowing, and curing process to achieve the physical connection. It is a thermoplastic polymer material is a thermoplastic properties, the fiber network or part of the fiber after heat softened and melted hot-melt powder, produce adhesion between the fibers, obtained after cooling reinforced fiber network and become thermally bonded nonwoven material. Adhesive material commonly used thermoplastic polymers, such as low melting point synthetic fibers, the thermoplastic polymer powder and polymer films.
Use of heat in three ways
Thermal bonding process includes hot melt bonding, hot bonding and ultrasonic bonding, in which the hot melt adhesive and bonding is most widely used.
Melt bonding process is the use of hot melt mixed with the drying room of the fibrous web medium is heated, the fiber network in the melt heat melting fibers or melt powder, molten polymer to flow and condense on the fiber crossing points, After cooling, the fiber network to obtain an adhesive reinforcement and become non-woven material. Development of hot-melt adhesive fibers to expand the application of hot-melt adhesive non-woven material, and the ratio of their choice depends primarily on the application and customer requirements, the mixing ratio of the hot-melt adhesive fibers is generally 10% to 50%, when a pre-bonded 5% to 10%, the actual production of nonwoven material should end application requirements ratio, thin products are usually made of 100% of the hot-melt adhesive fibers.
Hot melt adhesive process: short fiber (plus some hot-melt fibers) - opening song impurity - Mixed - carded - lapper - hot air drying - the finished product.
Thin air is generally used as high-grade non-woven napkin, without lapper, and hot melt cotton, imitation silk, hard cotton (mat) weight greater must undergo lapper. Lies in the hot melt method of drying, the hot air through the fiber web, the fiber is melted and joined together with each other to form a thin or thick sheet material fluffy floc.
Hot-rolled non-woven adhesive thermal bonding process in the application of late, to borrow a dyeing industry calender, hot light technology, due to its production speed, no waste problems, which has developed rapidly. The early 1980s, the United States with the rise of disposable diapers, hot-rolled non-woven polypropylene fabric material as diapers to replace the original viscose, polyester fiber as the main chemical bonding nonwoven material. Hot adhesive production speed, which is particularly suitable for thin spunbond nonwoven material reinforcement.
