Abstract
Abstract The invention discloses interlinings for stiffening parts of garments such as collars, cuffs, sleeves, shoulders and similar parts of outer garments. The interlinings are particularly intended for iron-on or sewn patches and comprise; an interlining backing material consisting of a fabric which may be woven, textile or knitted, or a fleece, or simply a plurality of fibres arranged side by side; textile flock fibres having a fibre length of 0.5 to 2.0 mm and a flock binder consisting at least in part of a polymer material which is applied to the backing material in the form of a screen like imprint. The screen like imprint may consist of a screen of dots, lines or small rods numbering from 140 to 700 per square inch. The flock binder includes micro dispersed filling materials fast to cleaning and abrasion resistant. The flocks are applied to the flock binder by an electrostatic force field of direct current with a voltage within the range 20 to 100 KV.
