Cotton/Polyester Blend Wash Guide

Our wash instructions are only a guide and might not be suitable for the care process you require. Please contact us if you are not sure about any of the information provided below.

• The first 4 to 5 minutes of the wash process should be carried out with a temperature below 40C to prevent setting any protein stains.
• The wash temperature can then be increased to 60C for white items or 70C should the soiling be cooking oil or grease based to encourage emulsification.
• If polyester/cotton is washed at 60C or above, a cool-down stage must be included between the high-temperature wash and cold temperature rinsing. The wash liquor temperature should reduce to 50C and a rate of approximately 4C per minute.
• High-temperature washing without a sufficient cool-down stage can result in Thermal Shock Creasing. This occurs when hot, soft and pliable polyester fibres are cooled too quickly whilst in a crumpled state. This results in small "broken ice" type creases on the fabric surface.
• Wash loads should be classified according to colour and soiling level.
• White items should be washed separately to prevent cross-contamination from coloured items.
• Do not wash with 100% cotton/100% polyester goods.
• Detergents containing optical brightening agents will improve the visual brightness of white polyester/cotton goods.
• For coloured goods, use a detergent that does not contain any optical brightening agents as this will mask the true shade and diminish the colour.
• Residual staining can be removed using oxygen-based bleaching agents but these should not be substituted for a good wash process with adequate detergency. Care and attention should be given to the conditions of use.
• Stain removal using Chlorine bleach (Sodium Hypochlorite) will chemically damage and accelerate the weakening of cotton fibres in the blend. Over/repeated use will cause the cotton fibres to degrade leaving a thin, shiny fabric due to the remaining polyester. On coloured items, Chlorine bleach will cause permanent colour loss/shade change and should be avoided.
• Natural or less commonly synthetic starches can be applied to poly/cotton linen to impart polish and stiffness where required. Starching should take place on the final water-based stage of the wash process after the fabric has been cleaned and all wash chemicals neutralised.
• Ironing should be done whilst damp to complete the drying process.
• Higher ironer bed temperatures (above 170C) on modern machinery can cause softening and distortion of polyester if consistently ironed in the same direction. Altering the direction of feed after each wash will minimise this effect if possible.
