What items Meltblown fabric must test?

Author: Date :2020-06-12 Views: order
The non-woven fabric means it is produced directly from fiber stage (in case of natural fibers) or from polymers (in granular stage) to fabric without the needing of an intermediate process like spinning or yarn formation. 
  What items Meltblown fabric must test?(图1)
The melt-blown nonwovens are made of thermoplastic synthetic polymer, directly from the polymer stage to randomly-laid nonwoven mat or fabrics by using the melt-blown spinning process. 
Surgical face masks are made with non-woven fabric, which has better bacteria filtration and air permeability while remaining less slippery than woven cloth. The material most commonly used to make them is polypropylene, either 20 or 25 grams per square meter (gsm) in density. Masks can also be made of polystyrene, polycarbonate, polyethylene, or polyester.
Test Items for Melt-blown fabric:
Weight is basic property of nonwovens, used to reflect the quality of products per unit area.
Waterproof property show the property that fabric is permeate, in medical and health care material, show the ability that product suffer liquid pressure, the bigger the better.
Electrostatic attenuation is an index to describe the dissipative electrostatic capacity of product. The better the antistatic performance, the lesser easy for electrostatic to gather on , and the better safety of the product.
Breaking capacity and elongation represent the maximum force required to break the product
Wear resistance can be applied to a variety of fabrics, reflecting actual wear and durability factors, among which the martindale method is often used.
Water permeability test reflects performance of the product against water.
As medical supplies, fabric’s ability to filter air is an important indicator. The permeability property reflects the ability of the product to pass through the gas at a specified pressure difference on both sides.In terms of the amount of gas passing through per unit time.
