Trevira CS: Maintenance

Maintenance of home and safety textiles

Trevira CS fabrics are easy to clean, dry quickly and retain their shape after washing. Unlike other materials, they need substantially less water and detergent in the wash, and – thanks to the short drying times – less energy for the drying process.

When it comes to maintenance, the functions of Trevira CS materials offer numerous advantages. This is because their properties, flame retardancy for example, or the bioactive effect, are firmly anchored in the fibre and are not lost as a result of usage or washing. Unlike fabrics that achieve their functions by means of a chemical coating, Trevira CS textiles are kind to the environment. When washed, there is no release of finish that is harmful to the environment.

Care of drapes and decorative fabrics

Depending on the article and the general operational context, it may be necessary to adapt the following care recommendations to the specific circumstances. Trevira CS materials should always be washed separately. In the case of doubt consult the manufacturer's instructions.



  • Take off curtain rings to avoid snagging
  • Wash drapes and decorative fabrics separately
  • Small full chamber machines (with no sub-sections, up to 18 kg content) are most suitable
  • Load machine with only one third of the usual amount

First wash cycle

  • Liquor ratio: 1:7 to 1:8
  • Water temperature: up to 30°C
  • Additives: 20-35 g/kg light-duty detergent (no additives) with non-ionic components
  • Duration of treatment: 10-15 minutes

Interim rinse

With heavily soiled drapes an interim rinse is recommended, adding 10 ml/kg caustic soda (sodium hydroxide, NaOH) (15%).

  • Liquor ratio 1:7 to 1:8
  • Water temperature: up to 30°C
  • Duration of treatment: 5-10 minutes

Second wash cycle

  • Liquor ratio 1:7 to 1:8
  • Water temperature:Normalwash 30-40°C
  • Additives: normal wash 10-15 g/kg
  • Wash without additives on non-ionic basis.
  • Duration of treatment: approx. 10 minutes 
  • In the case of doubt consult manufacturer's instructions


  • Liquor ratio 1:8 with hard water
  • Water temperature: cool slowly to approx. 20°C
  • Additives: a soft detergent at a concentration of a maximum 5 g/kg of load can be added to the final rinse. Avoid over-dosing at all costs.
  • Removal of water: gentle spin to approx. 50% residual moisture

Drying and ironing

  • Hang up flat at once to dry
  • Tumble dryer may be used
  • Fill ratio approx. 1:40 (one third normal fill)
  • Dry to outlet air temperature of 80°C
  • Then aerate with rotating drum until completely cool
  • Hang up immediately after removal from dryer or spread out without folding
  • Dampening or pressing may be necessary if curtains are left lying for some time

Repair work

  • Use only branded polyester sewing thread
  • Reduce thread tension on sewing machine
  • Number of stitches: approx. 4 to 5 stitches/cm 

Care of Indorama Ventures furniture upholstery fabrics

Cover fabrics – for instance for chairs – are often key to a good first impressions in many areas. Yet places where people sit a lot tend to mark and stain. Keeping Trevira CS upholstery fabrics clean is very simple.

A stain remover applied locally is adequate for small stains.
Where the staining is larger and/or severe, the whole piece of material should be cleaned:

  • Spray extraction devices achieve very good cleaning results
  • A non-ionic detergent can be added to the liquor
  • Brush or suction machines are not recommended (shampoo residues may have a negative effect on the burn behaviour of the material)
  • Ensure the cover fabric is adequately dried
  • Avoid applying heat when drying

Removable covers may be dry-cleaned.
It is possible to wash under light conditions at 60°C where stated by the fabric manufacturer (e.g. on the sewn-in label).


Pressure points

  • The nap and pile can be restored using steam (e.g. a steam iron), but on no account should the fabric surface be touched.


  • Velours can show shading; this is a purely optical effect
  • Simple brushing is sufficient to remedy this

Static electricity

  • May occur where there is low humidity (when heating is on in winter)
  • If it is not possible to increase humidity, spraying with a solution of 2 g/l common salt is recommended

Pilling and/or greyness

  • May occur where there is low humidity (when heating is on in winter)
  • If it is not possible to increase humidity, spraying with a solution of 2 g/l common salt is recommended

Stain key

Basically stains are best removed while they are still fresh and have not penetrated into the interior of the fibres. Dried-in marks have to be treated with a stain remover. The stain key gives details on what is possible and what procedures can be used.

The following general points apply:

  • Never rub the fabric hard
  • Rub gently with a clean absorbent cloth from the outside to the centre of the stain
  • For small marks, gentle treatment with a damp brush or sponge is sufficient
  • When using a damp sponge or brush the material should only be moistened, never made wet
  • When using stain removers the manufacturer's instructions should be noted to understand the effect on the under-fabric and the upholstery filling
  • Local stain removal is only useful for small stains
  • Cleaning of the complete material is recommended with larger and/or severe soiling
