Non-woven fabric is formed which does not require spinning and weaving, but the short fibers or filaments of textile or random orientation support column structure formed web, and mechanical, thermal or chemical methods such as reinforcement made .Non-woven breaking the traditional textile principle, and has a short process, production speed, high output, low cost, versatile, sources of raw materials and more features, a new generation of environmentally friendly materials, with water repellent, breathable, flexible, not combustion-supporting, non-toxic and non-irritating, rich colors and other characteristics.In the past 10 years, when the non-woven industry tends to globalization, the nonwoven fabric technology mainly shows the following categories:
Spunlace process is the high-pressure water jet to a fine one or more layers of fiber web, the fibers tangled with each other, whereby the fiber network to have a certain strength and reinforcement.
2.Thermal non-woven technology:
Thermally bonded nonwoven fabric refers to adding web fibrous or powdered hot melt adhesive reinforcement materials, fiber network and then cooled after heating and melting the reinforcement into cloth.
3.Wet nonwoven technology:
Wet nonwoven fabric is placed in an aqueous medium fiber material opening into a single fiber, while the mixing of different fiber materials, made of pulp fiber suspensions, suspended pulp conveyor into a network of institutions to the fibers in the wet state into a network again reinforcement into cloth.
4.Spunbond non-woven technology:
Spunbonded nonwoven fabric in the polymer has been extruded, stretched to form a continuous filament, the filament laying into a web, the web and then through the self-adhesive, thermal bonding, chemical bonding or mechanical reinforcement methods, so that web into a nonwoven fabric.
5.Meltblown nonwoven technology:
Meltblown nonwoven process: the polymer feeding --- melt extrusion --- fiber formation --- fiber cooling --- into the network --- reinforcement into cloth.
6.Acupuncture non-woven technology:
Acupuncture non-woven fabric is a dry non-woven, non-woven fabric is the use of acupuncture needles puncture role fluffy fiber mesh reinforcement into cloth.
