Polypropylene (PP) Spundbond and Melt-blown Compound Nonwoven Fabric Production Line (SMS, SMMS)
The characteristic of melt-blown nonwoven fiber includes its small fiber diameter, large surface area, soft, good hang down, low filtration resistance, good filtration efficiency as well as its low brute force and bad wear-resisting performance. And the fibre of spunbond nonwoven products is mostly continuous filament, having high intensity and large diameter range. The intensity of spundond nonwoven is higher than melt-blown nonwoven, while the diameter of spunbond fiber is bigger than that of the melt-blown. The low intensity and wearability limit the application of melt-blown nonwoven products greatly. But the shortcoming can be overcome by compounding the melt-blown nonwoven with the spunbond nonwovens. The compounded product has the strongpoint including high intensity, good wearability, good filtration and good performance of warm keeping and damp losing.
SMS nonwovens have the characteristics as follows:
Even and beautiful appearance
Extremely good air filtration
Isolation to the dust, the particle, alcohol, plasma, liquid and bacterium as well as the invasion and attack of the virus
Good physical performance
SMS nonwovens is safe, nonpoisonous and pollution-free to the environment. It is especially suitable for hygiene market, such as the cover surface material or side leak defending lining of sanitary towel, hygiene protection cushion, baby napkin and the adult cushion. Also it can be widely used for the disposable medical treatment clothes, industrial clothing, etc.
At present, The Melt blown system in the Production line of the SMS compound line and SMMS from our factory is imported from Japan.
There is big demand for SMS or SMMS. Along with the improvement of the living standards, the market of SMS products compound by spunbond and melt-blown will expand progressively. The SMS products are also competitive in the international market. In Asia, the panty-shape diapers are widely used in Japan, S. Korea, Singapore and China. The production can be exported after manufacturing.
Zhejiang Universal Packing Machinery Factory has successfully developed a SMS compound line cooperating with an Japan company making melt-blown line. The diameter of spunbond fiber is 1.8-3D, and that of melt-blown fiber can be 1-12 microns with the maximum speed of 250 meters every minute.
In addition, Zhejiang Universal Packing Machinery Factory cooperates with the top ranking Companies in the world developing SMS production line. The diameter of spunbond fiber can be 1.8-3D and the diameter of melt-blown fiber be 2-15 microns with the maximum production speed of 250 meters every minute. It had gained a good reputation among the users for its low cost and good performance.
