Spunbonded non-woven fabric is inexpensive and has good physical, mechanical, and aerodynamic properties. It is widely used in the manufacturing of sanitary materials, agricultural materials, household materials, engineering materials, medical materials, industrial materials, and other products. Taking spunbond non-woven fabric as an example, fabric testing institutions use polyamide polyester resin spunbond nonwoven fabric, which is widely used in the manufacturing of sanitary materials such as diapers and sanitary napkins due to its good softness and hand feel. Bavaria Testing, as a professional non-woven provider of various spunbond non-woven fabric testing services, can also provide qualification testing reports for national use and recognition. So, let’s learn about what spunbond non-woven fabric testing needs to know together!
Detection range of spunbond non-woven fabric
Inspection, polypropylene spunbond nonwoven fabric inspection, composite spunbond nonwoven fabric inspection, acrylic spunbond nonwoven fabric inspection, flame retardant PP spunbond nonwoven fabric inspection, spunbond wallpaper nonwoven fabric inspection, landscaping spunbond nonwoven fabric inspection, disposable bed sheet nonwoven fabric inspection, dustproof spunbond nonwoven fabric inspection, sofa spunbond nonwoven fabric inspection, disposable diaper spunbond nonwoven fabric inspection, diaper spunbond nonwoven fabric inspection Inspection of spunbond non-woven fabric for sanitary napkins
Inspection items
1. Internal quality inspection items: width deviation, unit area mass deviation rate, unit area mass variation coefficient, fracture strength, fracture elongation, ejection strength, equivalent pore size, vertical permeability coefficient, thickness
2. Appearance quality inspection items: perforation, poor incision, color difference, joint, melt, foreign objects, poor auxiliary mesh, soft seam breakage
3. You can choose to check the items. Dynamic perforation, puncture strength, aspect ratio, in-plane water flow rate, wet screen aperture, friction coefficient, UV resistance, acid and alkali resistance, oxidation resistance, temperature resistance, wear resistance, creep resistance, flame retardancy, splicing strength, hydrophobicity, constant load elongation, constant elongation load, and fracture elongation, etc
Inspection standards
GB/T 17639-2008 Synthetic Geotextiles – Long filament spunbond needle punched non-woven fabrics
FZ/T 64033-2014 spunbond hot-rolled non-woven fabric
FZ/T 64034-2014 spunbond method/melt blown method/spunbond method (SMS) non-woven fabric
FZ/T 64064-2017 Polyphenylene sulfide spunbond non-woven fabric filter materials
When checking whether non-woven fabrics are present on textiles, it is important to note that almost all inspection standards for selecting non-woven fabrics are named non-woven fabrics. Important projects vary depending on the type of non-woven fabric. Taking PP spunbond nonwoven fabric as an example, this nonwoven fabric mainly measures its flame retardant performance, analyzes it with a thermogravimetric analyzer, determines the limit oxygen index, and analyzes its flame retardant performance with TG testing.
The above introduction is about what needs to be learned in the testing of spunbond non-woven fabrics. If you need to know more, please feel free to contact us at any time!
