The special feature is that the integrated SMY causes the compression textile to contract only when heat is applied after donning, thus gradually building up the compression effect. This makes e.g. stockings significantly easier to put on, which will increase the acceptance of compression therapy. For the prompt transfer of the research results into industrial practice and thus into commercial products, the manufacturing technologies already established in the German textile industry were addressed. Therefore, suit-able SMY were implemented by means of melt spinning technology and the compression textiles by flat knitting technology, for which the necessary technological and product preparation know-how was provided especially for small and medium-sized enterprises (SMEs).

Textile structures with bio-modular deformation behavior for intervertebral disc protheses / Robert Tonndorf in TECHNICAL TEXTILES, Vol. 67, N° 2 (2024)  

[article]  inTECHNICAL TEXTILES > Vol. 67, N° 2 (2024) . - p. 24-27 Titre : Textile structures with bio-modular deformation behavior for intervertebral disc protheses Type de document : texte imprimé Auteurs : Robert Tonndorf, Auteur ; Dilbar Aibibu, Auteur ; Thi Anh My Huynh, Auteur ; Mareen Warncke, Auteur ; Chokri Cherif, Auteur Année de publication : 2024 Article en page(s) : p. 24-27 Note générale : Bibliogr. Langues : Multilingue (mul) Catégories : Couture Implants médicaux Implants orthopédiques Prothèse discale Textiles et tissus à usages médicaux Textiles et tissus à usages techniques Tissage en roseau ouvert Tissage tubulaire Tricot Index. décimale : 677.4 Textiles artificiels Résumé : The IGF project Spinetex laid the basis for the development of textile structures with bi-modular force-elongation behavior that have the potential to replicate the fibrous ring of biomimetic disc prostheses. To achieve the bimodular behavior of such structures, 3 textile technologies were investigated : stitching, open reed weaving (ORW), and tubular weaving with twines.
