Types of non-woven materials
The bag made of non-woven material is a typical environmental protection bag product, which is widely used in the market at present. Some people say that non-woven fabric is a kind of magic material. Why do they say that? What's the basis for that? I think it is closely related to the diversity of non-woven materials.
There are many kinds of non-woven fabrics, mainly including Spunlaced non-woven fabrics, wet non-woven fabrics, sewn non-woven fabrics and so on. Let's have a specific understanding.
Spunlace non-woven fabric, spunlace technology is to spray high-pressure micro water to a layer or multi-layer fiber network, so that the fibers are intertwined, so that the fiber network can be strengthened and has a certain strength.
Thermal bonded nonwovens refer to adding fiber like or powder like hot-melt bonding reinforcement materials to the fiber mesh, and then heating, melting and cooling the fiber mesh to strengthen the fabric.
Wet process non-woven fabric, this kind of non-woven fabric is to loosen the fiber raw materials placed in the water medium into a single fiber, at the same time, mix different fiber raw materials to make fiber suspension slurry, the suspension slurry is transported to the network forming mechanism, and the fiber is formed into a network in the wet state and then reinforced into a cloth.
Spunbonded nonwovens, spunbonded nonwovens are formed by extruding and stretching polymers to form continuous filaments, then the filaments are laid into nets, and then the nets are made into nonwovens by self-adhesive, thermal adhesive, chemical adhesive or mechanical reinforcement methods.
Needled non-woven fabric, needled non-woven fabric is a kind of dry non-woven fabric, needled non-woven fabric is to use the puncture effect of the needle to strengthen the fluffy fiber net into cloth.
The stitching method is to use the warp knitting coil structure to reinforce the fabric, yarn layer, non-woven material or their combination to make non-woven fabric.
Different environmental protection bag products are basically made of these different non-woven materials. Through different colors, styles, and material configurations, the shape of environmental protection bag products is tens of thousands of thousands of millions, which is deeply loved by consumers.
