Introduction

Nonwoven textiles are those which are neither woven nor knit, for example felt. General use hyphenates the word, but industrial use spells it as one word. Non-wovens are typically not strong (unless reinforced by a backing or densified). In the recent years non-woven material has become an alternative to polyurethane foam.
Non-woven fabric is typically manufactured by putting small fibers together in the form of a sheet (web) and then binding them either mechanically (as in the case of felt, by interlocking them with serrated needles such that the inter-fiber friction results in a stronger fabric), with an adhesive, or thermally {by applying binder(in the form of powder, paste, or polymer melt) and melting the binder onto the web by increasing temperature}.

Raw material

Non-woven materials are nowadays mainly produced from man-made fibers. Two synthetic polymers dominate the market: polypropylene and polyesters (mainly PET). Nonwovens are often application-designated as either durable or disposable. Nonwoven used as a housewrap to prevent water infiltration is a durable nonwoven. Nonwoven used as a facing on a baby diaper is a disposable or single-use nonwoven.

Application

Non-woven materials are used in numerous applications, including:

Hygiene
  • Baby diapers
  • Feminine hygiene
  • Adult incontinence products
  • Wipes
  • Bandages and wound dressings
Medical

  • Caps
Technical
  • Roll roofing and shingle reinforcement
  • Insulation backing
  • Battery electrode separators
  • Vinyl flooring reinforcement
  • Plastic surface reinforcement (veils)
  • Wall coverings
  • Honeycomb structural components
  • Ceiling tile facings
  • Circuit board reinforcement
  • Electrical insulation
Geotextiles
  • Soil stabilizers and roadway underlayment
  • Agriculture mulch
