Regular rayon is highly flammable; however, it can now be made flame-resistant by adding special chemicals to the viscose solution. Consequently, flame-resistant rayon can now be found in institutional textiles.

An MSDS sheet NEEDS to made available to any manufacturer that stores the material. Ask YOUR kiltmaker to provide an MSDS on THEIR Poly-Viscose (since different mills use different processes). If the material is imported, there should have been an MSDS sheet arrive with the first order. If not... they can easily get one.

CARE: Advancements in technology have lead to improvements in the maintenance and durability of fabrics made from rayon.

Rayon fabrics can be bleached. However, some finishes used on rayon can be sensitive to chlorine bleach.

Fabrics containing rayon should be dry-cleaned or hand washed.

Hand wash - Use cool to luke warm water, add gentle suds and gentle squeeze suds through fabric and rinse. Do not wring or twist the fabric. Shake or smooth out the fabric and place to dry on a rust proof hanger. Knitted fabrics should be laid flat to dry.

The fabric can be pressed while damp or dry at a medium setting. It is often best to press on the wrong side of the fabric or use a pressing cloth while pressing on the right side of the fabric.

Damage can occur to rayon fabrics from acids, silverfish and mildew. Sunlight is not harmful.

IF there are flame retardant features in the material, this will survive better with the proper care and cleaning.
