What is the difference between PP non-woven fabric and spunlace non-woven fabric?
The difference between PP non-woven fabric and spunlace non-woven fabric, PP means that the raw material of non-woven fabric is PP, and spunlace non-woven fabric is said to be a production process. The two kinds of non-woven fabrics mainly differ from the process flow. The specific cloth is not essentially different. Now I will explain the PP non-woven fabric in detail: The exact name of the non-woven fabric should be a non-woven fabric, or non-woven fabric, because it is a fabric that does not need to be spun woven fabric, but the woven short fibers or filaments are oriented or randomly arranged to form a web structure. It is then reinforced by mechanical, thermal bonding or chemical methods.
Characteristics of non-woven fabrics · Non-woven fabrics break through the traditional textile principle, and have the characteristics of short process, fast production speed, high output, low cost, wide application, and many raw materials. Uses · Its main uses can be roughly divided into: (1) medical, sanitary non-woven fabrics: surgical gowns, protective clothing, sterile cloth, masks, diapers, civilian rags, wipes, wet wipes, magic towels, Soft towel roll, beauty products, sanitary napkins, sanitary pads and disposable sanitary cloth, etc.; (2) non-woven fabrics for home decoration: wall coverings, tablecloths, bed sheets, bedspreads, etc.; (3) non-woven fabrics for clothing : lining, adhesive lining, flakes, styling cotton, various synthetic leather base fabrics, etc.; (4) industrial non-woven fabrics; filter materials, insulating materials, cement bags, geotextiles, coated fabrics, etc.; Agricultural non-woven fabrics: crop protection cloth, nursery cloth, irrigation cloth, heat preservation curtain, etc.; (6) Other non-woven fabrics: space cotton, thermal insulation material, oil absorbing felt, smoke filter, bag tea bag, etc.
Types of non-woven fabrics and non-woven fabrics can be classified according to different production processes: 1. Spunlaced non-woven fabric: a high-pressure fine water jet is sprayed onto one or more layers of fiber webs to entangle the fibers with each other, thereby . The fiber web is reinforced and has a strong string of characters 5 2 . Heat-sealable non-woven fabric means that a fibrous or powdery hot-melt adhesive reinforcing material is added to the web, and the web is further fused and cooled to form a cloth. 3, pulp airlaid non-woven fabric: also known as dust-free paper, dry papermaking non-woven fabric, which uses airlaid technology to open the pulp fiberboard into a single fiber state, and then use airflow to make the fiber agglomerate On the mesh curtain, the fiber web is then reinforced into a cloth. 4. Wet-laid non-woven fabric: the fiber raw material placed in the water medium is opened into a single fiber, and at the same time, different fiber raw materials are mixed to form a fiber suspension slurry, and the suspended pulp is transported to a web forming mechanism, and the fiber is in a wet state. Forming the net and then reinforcing it into cloth 0.5, spunbonded non-woven fabric: after the polymer has been extruded and stretched to form continuous filaments, the filaments are laid into a net, and the web is then bonded by itself and thermally bonded. Chemical bonding mechanical reinforcement method to make the web into a non-woven fabric. 6, melt-blown non-woven fabric: the process: polymer feed --- melt extrusion --- fiber formation --- fiber cooling --- net --- reinforcement into cloth. 7 needle-punched non-woven fabric : It is a kind of dry non-woven fabric. The needle-punched non-woven fabric is a puncture effect of a needle, and the fluffy web is reinforced into a cloth 2.8. The stitch-bonded non-woven fabric is a kind of dry non-woven fabric. The knitting method is to use a warp knitting coil structure to reinforce a web, a yarn layer, a non-woven material (for example, a plastic sheet, a plastic thin metal foil, etc.) or a combination thereof to form a nonwoven fabric.
