Classification of non-woven fabrics (1)

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.

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

  1. Spunlaced non-woven fabrics: Spunlaced process is to spray high-pressure micro-water into one or more layers of fiber network, so that the fibers are intertwined, so that the fiber network can be strengthened and have a certain strength.
  2. Thermal bonded non-woven fabric: Thermal bonded non-woven fabric refers to adding fibrous or powdery hot-melt bonded reinforcing materials into the fabric, which is then strengthened by heating, melting and cooling.
  3. Pulp air-laid non-woven fabrics: air-laid non-woven fabrics can also be 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 agglutinate the fibers on the screen curtain, and then reinforce the fibernet into cloth.
  4. Wet non-woven fabrics: Wet non-woven fabrics are made by loosening the fibre raw materials placed in the water medium into single fibers and mixing different fibre raw materials into fibre suspension slurry. The suspension slurry is transported to the netting mechanism, and the fibers are netted and consolidated into fabrics in the wet state.
