Definitions

• the invention relates to an insert for use as an embroidery fixation insert, consisting of a textile carrier material which is coated with an adhesive mass, wherein the adhesive composition comprises a water-soluble, thermoplastic polymer.
• lining fabrics or nonwovens are laminated together with a textile layer configured as an outer material in a fixing press. Subsequently, reinforced and unreinforced parts are joined together, sewn and shaped if necessary by shaping.
• the polymers known from DE 100 32 769 A1 for adhesive compositions based on (co) polyamides, polyvinyl alcohols and / or (co) polyesters can not be imprinted on water-soluble nonwovens in the form of an aqueous dispersion by a rotary screen printing method, since the water in the Adhesive mass leads to selective dissolution of the water-soluble nonwoven fabric. Triggered or printed areas of the water soluble nonwoven result in an unsightly, rough surface of the adhesive coated nonwoven fabric.
• the invention is therefore based on the object to design the adhesive compositions known from the prior art in such a way and further that they can be easily used for water-soluble deposits, especially for nonwovens.
• the aforementioned insert is characterized in that the adhesive composition is designed as an aqueous polymer dispersion and / or as a polymer solution.

• Vinylpyrrolidones with polyvinyl acetate moieties are less hygroscopic at room temperature than unmodified vinylpyrrolidones. Therefore, the coated deposits do not stick when rolled up.
• the adhesive composition could comprise polyols or polyglycols.
• polyols and / or polyglycols By adding polyols and / or polyglycols, the melting range of a polymer, in particular the vinylpyrrolidones, can be changed, in particular lowered, or the melt flow of the polymer can be adapted to the respective applications.
