Nonwoven medical protective material spunmelt vs spunlace

Non-woven medical protective materials were developed in the 1990s. At that time, some developed countries in Europe and America used advanced non-woven technology to develop a low-cost spunlace non-woven fabric with appearance and feel close to traditional textiles, which became a substitute for traditional textiles. The excellent material. Up to now, the processing methods of non-woven medical protective materials have been relatively mature. According to the different preparation technologies, currently there are mainly spunmelt (including flash evaporation), spunlace and needle punching.

Spunbond nonwoven technology, meltblown nonwoven technology, flash nonwoven technology

As a protective material, spunbond nonwovens meet the requirements in terms of strength and comfort, but are relatively weak in barrier properties. In response to this problem, fine denier spunbond technology has become a major research focus. The two-component spunbond spunlace technology first invented by the German Freudenberg company uses a hollow orange-petal spinning assembly to extrude a thin stream of melt from the spinneret, then cools, blows, and draws. The formed filaments are laid on the web curtain, and then the high-pressure spunlace technology is used to open and fix the web. Its barrier performance is relatively better than ordinary spunbonded or spunlace nonwoven materials, so it can be used as a medical protective material. Mogul, a Turkish nonwoven fabric manufacturer, recently launched a material that can be used in surgical gowns. The fiber after opening is 100 times thinner than hair, which can block microorganisms, has anti-blood and alcohol properties, and has good properties. Its moisture absorption, breathability and heat insulation, the microporous structure and protective properties of this nonwoven material make it an ideal material for medical protective clothing. The biggest feature of the melt blown method is that the fiber is very thin, the structure is fluffy after self-bonding, the porosity is high,
