What are the Testing Items for PP Spunbond Nonwoven Cloth?

PP spunbond nonwoven cloth is widely used in the manufacture of sanitary materials, agricultural materials, living materials, engineering materials, medical materials, industrial materials, and other products because of their low price, good physical and mechanical properties, and aerodynamic properties. In addition, pp spunbond nonwoven cloth is widely used in the manufacture of sanitary materials such as diapers and sanitary napkins because of their excellent softness and excellent touch.

PP spunbond nonwoven cloth manufacturing process produced by spunbond polypropylene suppliers: after the PP polymer is extruded and stretched to form continuous filaments, the filaments are laid into a net, and the fiber net is then bonded by itself, thermally bonded, chemically bonded, or mechanically reinforced to make the web into a non-woven fabric.

PP spunbond nonwoven cloth not only has high-temperature resistance, good performance, aging resistance, UV resistance, high elongation, good stability, and air permeability but also are corrosion resistance, sound insulation, mothproof and non-toxic.

Let's share with you what testing items are available for spunbond polypropylene fabric.

1. Intrinsic quality testing items: width deviation, mass deviation per unit area, coefficient of variation of mass per unit area, breaking strength, breaking elongation, burst strength, equivalent pore size, vertical permeability coefficient, thickness.

2. Appearance quality inspection items: holes, poor trimming, color difference, joints, frit, foreign matter, poor auxiliary net, soft folds.

3. Optional testing items: dynamic perforation, puncture strength, vertical and horizontal strength ratio, in-plane water flow, wet screen aperture, friction coefficient, UV resistance, acid and alkali resistance, oxidation resistance, temperature resistance, abrasion performance, creep properties, flame retardant properties, splicing strength, oleophobic properties, hydrophobic properties, elongation at constant load, load at constant elongation, elongation at break, and so on.
