Production of nonwoven polypropylene fibers mainly (PP), polyester (PET). In addition, polyamide (PA), viscose, acrylic, Polyethylene (HDPE), polyvinyl chloride (PVC). According to application requirements, application-oriented and non-woven disposable divided into two major categories of durable.
According to the production process is divided into:
1. Spunlace nonwoven: spunlace process is the high-pressure water jet to a fine layer or multi-layer fiber web so that the fibers entangled with each other, so that the web can be reinforced rather have a certain strength.
2. Non-woven heat: heat-bonded nonwoven web means adding fibrous or powdered hot melt adhesive reinforcement materials, fiber network and then cooled after heating and melting the reinforcement into cloth.
3. Pulp airlaid nonwoven fabric: airlaid nonwoven fabrics can be called airlaid dry papermaking nonwoven fabric. It is the use of airlaid technology wood pulp fiberboard opening song into a single fiber state, and then use the airflow method on the fiber aggregation into a network of screens, fiber network and then reinforcement into cloth.
4. Wet nonwoven fabric: wet nonwoven fabric is placed in an aqueous medium open pine into a single fiber raw fiber, while the mixing of different fiber materials, made of pulp fiber suspensions, suspended pulp conveyor to form a network organization, fibers and then the wet state into a network reinforcement into cloth.
5. Spunbond nonwoven fabric: spunbonded nonwoven fabric after the polymers have 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, the fiber network into a nonwoven fabric.
6. Meltblown nonwoven: meltblown nonwoven process: the polymer feeding --- melt extrusion --- fiber formation --- fiber cooling --- into the network --- reinforcement into cloth.
7. Acupuncture non-woven fabric: Non-woven acupuncture is a dry non-woven, non-woven fabric is the use of acupuncture needles puncture role fluffy fiber mesh reinforcement into cloth.
8. Non-woven stitch: stitch non-woven fabric is a dry non-woven fabric, stitch using warp coil structure of the fiber network, yarn layer, non-woven material (such as plastic sheets, plastic thin metal foils etc.) or a combination thereof reinforcement, to form a nonwoven fabric.
9. Hydrophilic nonwoven fabric: mainly used for the production of medical materials to get a better feel and do not scratch the skin. Such as sanitary napkins, sanitary pads is the use of a hydrophilic nonwoven fabric hydrophilic function. |
