Document Summary
A chemical treatment applied to cotton bres or fabrics to permanently impart a greater af nity for dyes and various chemical nishes. Mercerizing also gives cotton cloth increased tensile strength, greater absorptive properties, and, usually, a high degree of lustre, depending on the method used. This occurs because the bers and yarns are under tension when the fabrics are made. Later when the fabric is wet in a tensionless condition, relaxation occurs. Made from the bers of the ax plant. 25 to 150 mm (1 to 6 in) and average 12-16 micrometers in diameter. There are two varieties: shorter tow bers used for coarser fabrics and longer line bers used for ner fabrics. Flax bers can usually be identi ed by their nodes which add to the exibility and texture of the fabric. Used as stuf ng for pillows, mattresses, and upholstery, as insulation material, and as a substitute for absorbent cotton in surgery.
