Design and development of experimental models for textile structures integrated in wound dressings applied in curative therapy of inflammatory skin diseases, using specific instruments of descriptive statistics

Wound dressing is a key factor of the wound management system, having as main objective the stimulation of thehealing process for a variety of inflammatory skin diseases. To maximize the therapeutic effects, innovative medicaldevices with integrated drug delivery system become of real interest during the last decade. For the realization of theoptimal woven fabrics used as a substrate for various active principles, such as propolis and cinnamon essential oil, themultivariate linear regression analysis was used to elaborate the conceptual models on the basis of which theexperimental models of the textile supports were designed. Using as input data the characteristics of the selected yarns(breaking force, elongation at break, torsion/twist, hygroscopicity), one can predict the structural parameters of thewoven fabrics (raw materials, yarn density, lengths of the underlaps) and also the assembly and adjusting parametersfor the machinery from weaving preparation and weaving sectors (advance and height of the drum, reed width,drawing-in, input/output of the gripper, cross unevenness reed, stationary in maximum open lease, the moment of thegrippers opening, impulse time, the moment of the shaft smoothening, etc.). The validation of the elaborated conceptualmodels it was confirmed by the registered yields in the range of 88–96 %, during the weaving process
