Knowra Nonwoven fabric Nonwoven fabric A textile sheet made by bonding or entangling fibers without weaving or knitting yarns. Its structure comes from the fiber web and the method used to stabilize it.
Spunbond process : A process that forms continuous filaments, lays them into a web, and bonds the web into fabric. It makes strong, continuous-filament webs in a single production line.
Fiber web : An arrangement of fibers spread into a sheet before or during bonding. It is the intermediate structure that bonding turns into a nonwoven.
Surgical mask : A loose-fitting medical mask designed to limit the spread of droplets from its wearer. Its filter layers commonly use meltblown nonwoven fabric.
Woven fabric : A textile made by interlacing two perpendicular sets of yarns. Woven fabric derives its structure from yarn interlacing, unlike a bonded fiber web.
Textile recycling : The recovery and processing of discarded textile materials for reuse or conversion into new products. Mixed fibers, binders, and layered structures complicate nonwoven recycling.
Meltblown process : A process that uses high-velocity hot air to draw molten polymer into fine fibers and collect them as a web. Its fine fibers create nonwovens suited to filtration and barrier layers.
Polypropylene : A thermoplastic polymer widely used in fibers, packaging, and molded products. Its low cost and heat-bonding behavior suit high-volume nonwovens.
Geotextile : A permeable textile used with soil or rock in civil engineering and construction. Nonwoven geotextiles separate, filter, or protect soil layers.
Knitted fabric : A textile made by interlooping one or more yarns. Knitting forms loops from yarns rather than bonding a fiber web.
Polypropylene recycling : The collection and reprocessing of polypropylene waste into usable material. Polypropylene nonwovens can be recyclable when collection and product design permit.
