Merging Footwear Design and Functionality

Kutnjak-Mravlinčić Suzana, Akalović Jadranka, Bischof Sandra

Autex Research Journal

2020

Vol. 20, no. 4

372--381

Functionality and appearance are key aspects of good footwear. Developments in recent science and technology offer a wider scope of innovations, contributing to diversity and higher complexity of the production concept of footwear. Contemporary industrial footwear market offers a practically limitless number of new design and fashion solutions, often of quite similar appearance, but with significant differences in quality level, both regarding manufacture, raw material content, durability, and in some special functional finishes. The materials for footwear manufacture are functionalized for functional protective purposes, such as antimicrobial, waterproofing, fire resistant, wear and tear resistant, and recently for some therapeutical purposes. Novelties in material functionalization for the materials built in the footwear are most often promoted and presented on tags and labels and are used as advertisement issues, while some functionalities have become a logo for some brands.

Isolation of α-tocopherol from Cotton Cosmetotextiles

Cotton fabrics were treated with cosmetic substances based on α-tocopherol and cyclodextrine. Isolation of α-tocopherol from cotton cosmetotextiles was performed using three different techniques: stirring, Soxhlet and microwave extraction. High performance liquid chromatography (HPLC) was optimised and applied for the quantification of α-tocopherols in the isolates. The results revealed that all techniques are applicable for the isolation of α-tocopherol from cotton cosmetotextiles. The HPLC method proved to be the most convenient for the quantification of α-tocopherol from cotton fabrics.

W pracy obrabiano tkaniny bawełniane substancjami kosmetycznymi na bazie tokoferolu i cyklodekstryny. Izolację tokoferolu z kosmetotekstyliów bawełnianych przeprowadzono stosując trzy różne techniki: mieszanie, Soxhleta i ekstrakcję mikrofalową. Do oznaczenia ilościowego tokoferoli w izolatach zastosowano wysokosprawną chromatografię cieczową (HPLC). Wyniki wykazały, że wszystkie techniki mają zastosowanie do izolacji α-tokoferolu z kosmetotekstyliów bawełnianych. Metoda HPLC okazała się najbardziej dogodna do ilościowego oznaczenia α-tokoferolu z tkanin bawełnianych.
