Definitions

• the invention relates to a fixable interlining with a coating based on a copolyamide.
• the invention also relates to a method for producing the interlining and its use.
• Interlinings consist of a substrate, e.g. a woven fabric, a knitted fabric or a nonwoven fabric.
• the base material of the substrate can be for a fabric Cv / PES, PES, Co, Co / PES, Co / CV, Co / Wo, as well as for knitwear PES, Cv / PES, PES / Co, PA / Co, PA / CV and for Nonwovens PA, PA / PES, PES, PES / Cv.
• Heat-sealable thermoplastic adhesives e.g. Copolyester, copolyamides, polyethylene, ethylene vinyl acetate, polyvinyl chloride used.
• the coating is e.g. applied as powder point, colon, paste point or by scatter coating.
• An insert is cut from the insert material and fixed with an outer material by gluing.
• a coating is required to ensure very good adhesion, security against kickback and puncture as well as a soft grip.
• Fixations can cause problems when maintaining textile products. For this reason too, care labels were created in the form of symbols for washing, bleaching, ironing, chemical cleaning and drying, which inform the consumer about suitable care treatments. Improper care treatments can make a garment unusable. There is currently no known fixer that meets the maximum requirements of all care treatments. The highest requirements are currently:
• Washing maximum washing temperature 95 ° C.
• Drying in a tumbler Care process: No restriction regarding the drying temperature after the washing process
