Affect the SMS non-woven fabric permeability, blocking performance reasons

by:Sunshine     2020-09-24
The homogeneous degree of the product is the basic performance indexes of the SMS composite nonwovens. Typically, spinning system, the more homogeneous degree of the product will be the better. The other performance index of the SMS products related to the purpose of the product, is similar with melt-blown products requirements. Mainly the permeability, blocking performance ( Hydrostatic pressure) And so on. Or permeability barrier property is must possess the basic function of health care products. SMS products permeability or barrier property mainly depends on the M floor product or hydrostatic pressure, permeability and the main factors influencing the permeability or barrier property of product is the M size, uniformity and quantitative M layer fabric. S mainly to protect and strengthen the effect to the M floor, M layer under the action of external force is to avoid wear and deformation or damage of the structure. S, of course, the better the uniformity, the smaller denier, its support for the M layer, protection is also more obvious, to improve the hydrostatic pressure of SMS products will have a better effect. In SMS composite products, the greater the proportion of M layer, the greater the quantitative or layers, the more the hydrostatic pressure or blocking performance is better, the same proportion or quantitative M layer, cooperate with the fine denier, the better the uniformity or quantitative S layer, the greater the hydrostatic pressure or blocking performance.
