What is the difference between pp and spunlace non-woven fabrics? How is the production process different?

The difference between pp non-woven fabric and spunlace non-woven fabric is that the raw material of pp is non-woven fabric, while spunlace non-woven fabric refers to the production process. These two kinds of non-woven fabrics are mainly different from the technological process, and the specific fabrics are not fundamentally different. Now explain PP non-woven fabric in detail: non-woven fabric should be the exact name of non-woven fabric or non-woven fabric. Because it is a fabric that does not need to be woven and woven, it is only made of woven short fibers or filaments, arranged in a directional or random manner to form a fiber network structure, and then through mechanical, thermal reinforcement or chemical methods. The difference between Pp nonwovens and spunlace nonwovens The characteristics of nonwovens nonwovens break through the traditional textile principles, with short process flow, fast production speed, high output, low cost, wide range of use, and multiple sources of raw materials Features. The main uses of non-woven fabrics can be roughly divided into: (1) Medical and sanitary non-woven fabrics: business clothes, protective clothing, disinfection wraps, masks, diapers, household dish cloths, wipes, wet towels, magic towels , Soft towel rolls, beauty products, sanitary napkins and disposable sanitary cloth; (2) Non-woven fabrics for home decoration: wall coverings, tablecloths, bedspreads, bedspreads, etc.; (3) Non-woven fabrics for clothing: linings, adhesive linings , Flocculation, special-shaped cotton, various synthetic leather backing fabrics, etc.; (4) Industrial non-woven fabrics; filter materials, thermal insulation materials, cement packaging bags, geotextiles, covering fabrics, etc. (5) Non-woven agricultural cloth: crop protection cloth, nursery cloth, irrigation cloth, thermal insulation curtain, etc.; (6) Other non-woven fabrics: non-woven fabric types such as space cotton, insulation materials, linoleum, smoke filter, tea bags, etc. According to different production processes, non-woven fabrics can be divided into: 1. Spunlace non-woven fabrics: the high-pressure micro-water jet is divided into one or more layers of fiber nets, so that the fibers are intertwined, so that the fiber network is strengthened and has a certain Strength of. 2. Thermal non-woven fabric: refers to the fiber network in which fibrous or powdery hot-melt bonding reinforcing materials are added to the fiber network, and then heated and melted to cool the fiber network. 3. Pulp air net non-woven fabric: also known as dust-free paper, dry paper non-woven fabric. It uses the airflow network technology to open the wood pulp fiberboard into a single fiber state, and then uses the airflow method to bond the fibers in the net curtain, and the fiber net is reinforced into a cloth. 4. Wet non-woven fabric: the fiber raw materials placed in the water medium are opened into single fibers, and different fiber raw materials are mixed at the same time to make a fiber suspension slurry, which is transported to the network organization, and the fiber is in a wet state Become a mesh, and then reinforced into a cloth. 5. Spunbond nonwoven fabric: it is extruded in polymer, stretched and formed into continuous filaments, which are spread into a net shape, and then bonded by the fiber web itself, thermally bonded, chemically bonded or mechanically reinforced The method to make the fiber network into a non-woven fabric. 6. Melt-blown non-woven: Process: polymer feeding-melt extrusion-fiber forming-fiber cooling-mesh-strengthening into cloth. 7. Needle-punched non-woven fabric: It is a dry non-woven fabric. The needle-punched non-woven fabric uses the perforation effect of needle punching to reinforce the fluffy fiber web into a cloth. 8. Sewing non-woven fabric: use dry non-woven fabric. The stitching method is to make a non-woven fabric by using a warp-knitted loop structure to reinforce fiber mesh, yarn layers, non-woven materials (such as plastic sheets, plastic foils, etc.) or a combination thereof.
