Airlaid

Short staple (6mm) SAF™ can be processed on all commercial airlaid production equipment and is typically blended with wood pulp and thermal bondable fibre. Webs with up to 60% SAF™ content can be achieved at fabric weights between 80-1,000gsm.

Product web technologies include:

  • BBAL/LBAL = Binder-bonded airlaid/Latex bonded airlaid
  • MBAL = Multi-bonded air-laid
  • HBAL/XBAL = hydrogen-bonded air-laid or x-bonded air-laid

Drylaid

SAF™ can be blended with a wide range of fibres and processed through standard cotton carding systems for nonwoven web forming. Webs containing up to 85% SAF™ can be produced at fabric weights between 10-2,000gsm.

Blending and bonding

SAF™ can be blended with the full range of synthetic and natural fibres.

  • Thermally-bonded (typically when bonded with bi-component fibres)
  • Needle-punched
  • Stitch-bonded
  • Latex-bonded (with a fibre matrix , SAF™ will dry back to its original fibre shape)
  • Steam/calendar-bond (the steam causes the surface of SAF™ to stick via hydrogen bonding to cellulosic fibre, e.g. wood pulp or viscose)
  • Bonding combinations (multi-bonds)

Yarns

SAF™ can be processed by all well-known staple fibre spinning systems. Typically, SAF™ would be blended with other synthetic fibres such as polyester, nylon, cellulose and aramids. These fibre blends are normally processed using the cotton and semi-worsted systems.

A wide range of spun yarns can be produced using common spinning technologies, including OE, Ring, Hollow Spindle, Repco, Dreft and Pavena.


SAF™ is a non-irritant, safe to handle and is FDA/EFSA listed for use as an absorbent in food packaging. It can be blended with a range of synthetic and natural fibres. Due to excellent integration during conversion into fabrics and yarns, no adhesives or thermal-bonding treatments are required to keep the fibres in place.
