The machine for making PP spunbond is also called nonwoven punching machine. It adopts the overall modular design, the structure is compact and reasonable. The control part is controlled by an advanced PLC microcomputer, and the speed of the frequency converter of the internationally known brand is adjusted.
Where do the raw materials for the machines for PP spunbond making machine come from?
What is the difference between PP nonwoven and SMS nonwoven?
What is the production process of PP spunbond making machine?
The raw materials used in the machine for the production of PP spunbond are mainly by-products produced in petroleum refining. Plastic particles made of polyethylene and polypropylene. Short fibers or filaments are obtained by high-temperature melting, spinning and other processes, and then by friction, cohesion and bonding. Or a combination of these processes is oriented or arbitrarily arranged to produce sheets, webs or nonwovens called "nonwovens" because they do not require weaving, but have the appearance and certain properties of a fabric.
1. The full name of PP is polypropylene, and PP nonwoven is nonwoven or nonwoven. It is a nonwoven fabric formed by forming fibers by airflow or machines, then spunlace, needle punching or hot rolling, and finally after finishing. Due to the nature of pp itself, the final performance of the fabric is high strength, but poor hydrophilic performance. Usually, the process sequence of ppnw is spinning into a web and hot rolling the reinforcement. Generally, ppnw has a wide range of applications, such as packing bags, surgical protective clothing, workwear, etc.
2. SMS nonwoven fabric is a composite nonwoven fabric, which is a composite product of spunbond and meltblown. It has the advantages of high strength, good filtration performance, no glue and non-toxicity. At present, it is mainly used for medical and health occupational safety products such as surgical coats, surgical caps, protective clothing, hand wash clothing, handbags, etc. used. In the nonwoven process, there is a sandwich structure material called SMS, which is a spunbond meltblown spunbond structure. This material combines spunbond with good strength and melt blown fabric. Good barrier properties It is widely used in medical and health materials.
The production of PP spunbond making machines mainly includes substrate manufacturing, post-processing and other compounds, including fiber preparation, nonwoven forming, reinforcement and post-processing. Or mechanically connected to a mesh and then by spunlace, acupuncture or hot rolling etc. reinforced and finally processed into a non-woven fabric after finishing. Downstream companies process nonwovens into surgical gowns, sanitary napkins, diapers, wet wipes and other products that are sold to end users.
DongYang AoLong Non-Woven Equipment Co., Ltd. The factory has many years experienced engineers and a service team to develop and install our PP spunbond production lines of brand "A.L" of 1.6 M, 1.8 M, 2.4 M, 3.2 M, 4 M and 4.2 M with various models such as S, SS, SXS, SSS, SMS, SMMS and SMMSS etc.
