SAF - The Chemistry
The chemistry on which SAF is based
has been extensively tested to establish its
safety for use status in application areas requiring
a high degree of toxicity and regulatory
approval. Studies have included
allergenicity, irritation, dermal, genetic, reproductive,
and ingestion research.
Technical Absorbents manufactures its
own patented polymer system to produce
SAF – an aqueous solution which is extruded
into a hot air stream in order to dry
and cure the polymer, resulting in the formation
of SAF filaments. These are then
cooled, and precision cut into a range of staple
lengths before being dried, cross-linked,
conditioned and baled for despatch.
The manufacturing process is extremely
versatile, allowing for precise tailoring and
control of all required fibre parameters. Inhouse
quality control systems ensure fibre
is produced to exacting specifications.
SAF can be converted into numerous fabric
and yarn structures using the following
web-forming processes:
• Air-laid
• Dry-laying – carded
• Staple fibre manufacture
• Wet-laid
SAF can be blended with a full range of
synthetic and natural fibres to meet customers
end requirements. Following the
web-forming process, SAF webs can be
bonded to allow for the formation of an extremely
diverse fabric portfolio.
