This knowledge is needed for spunbond testing

Spunbonded nonwovens are cheap, have good physical and mechanical properties and air mechanical properties, and are widely used in the manufacturing of sanitary materials, agricultural materials, living materials, engineering materials, medical materials, industrial materials and other products. Taking the long fiber spunbonded nonwovens as an example, the spunbonded nonwovens made of polyamide polyester resin are widely used in the manufacture of diapers, sanitary napkins and other sanitary materials because of their excellent softness and good skin touch. As a professional non-woven fabric testing organization, Bain testing can provide a variety of non-woven fabric testing services, and provide qualification testing reports that can be used and recognized nationwide.


Detection range of spunbond nonwovens


Polyester spunbond non-woven fabric detection, polypropylene spunbond non-woven fabric detection, composite spunbond non-woven fabric detection, polypropylene spunbond non-woven fabric detection, flame retardant PP spunbond non-woven fabric detection, spunbond wallpaper non-woven fabric detection, garden greening spunbond non-woven fabric detection, disposable sheet spunbond non-woven fabric detection, photography background spunbond non-woven fabric detection, dust-proof spunbond non-woven fabric detection, sofa spunbond non-woven fabric detection Cloth testing, disposable diaper spunbond non-woven testing, diaper spunbond non-woven testing, sanitary napkin spunbond non-woven testing


Test items of spunbond non-woven fabric


1. Internal quality inspection items: width deviation, quality deviation rate per unit area, quality variation coefficient per unit area, breaking strength, elongation at break, breaking strength, equivalent aperture, vertical permeability coefficient, thickness

2. Appearance quality inspection items: holes, poor trimming, color difference, joints, frits, foreign matters, poor auxiliary network, soft fold

3. Optional test items: Dynamic perforation, puncture strength, vertical and horizontal strength ratio, in-plane water flow, wet sieve aperture, friction coefficient, UV resistance, acid and alkali resistance, oxidation resistance, temperature resistance, wear performance, creep performance, flame retardant performance, splicing strength, oil drainage performance, hydrophobicity, load elongation, load elongation at break etc.


Test standard for spunbond nonwovens


GB / T 17639-2008 geosynthetics - filament spunbond needle punched Geotextiles

FZ / T 64033-2014 spunbond hot rolled Nonwovens

FZ / T 64034-2014 spunbond / melt blown / spunbond (SMS) non woven fabrics

FZ / T 64064-2017 polyphenylene sulfide spunbond spunlaced nonwoven filter material

When testing the non-woven fabrics, we must pay attention to the selection of non-woven fabrics testing standard names are basically named nonwovens. Testing different kinds of spunbonded nonwovens focuses on different items. Taking PP spunbond non-woven fabric as an example, this non-woven fabric mainly tests its flame retardant performance. We can use thermogravimetry analyzer to analyze, measure the limit oxygen index, and TG test to analyze its flame retardant performance.
