Knitted medical stockings destined for the treatment of venous diseases must fulfill proper functions during wear, with some restrictions of criteria demanded by the raw material and the design parameters (including gradual compression and size). As the end use of the knitted stockings implies a complex of stresses applied in more than one direction, the grab method was used in an original way to assess the fabric behavior in three directions (wale, course and bias), with a few seconds time delay between tests. This testing method was applied in order to determine the capacity of medical compression hosiery to retain its designated gradual compression after repeated wearing—washing cycles. Additionally, the study revealed the manner of preservation of the gradual compression following the wearing—washing process, in connection with the patients’ physical dimensions for panty hosiery.

The work presents chemical procedures used to obtain a film or a hydrogel after hydrolyze treatment of hair at the temperature of 150oC and the pressure of 4.9 atm. In order to obtain the hydrogel, this treatment is followed by a stage of oxidation with hydrogen peroxide, and a stage of reduction with Na2S2O4 or, in another variant, a stage of oxidation with hydrogen peroxide and a treatment with NaOH in alcoholic medium, to form natrium cationic groups. The protein chains with sulphonic groups and natrium cations determine opposite electrostatic interactions, with the formation of a polymer loop that incorporate water. The evaluation of formed hydrogel was carried out by determining the swelling degree. We have used optical and SEM photomicrographs to determine morphological organization, and EDAX micropictures for chemical modifications. A cellulose film realized by growing Gluconoacetobacter xylinus bacteria was used as control sample.

Considered a specific niche, women's clothing is strongly influenced by trends in colors, pattern and fashion but also by the feelings about an adequate durability, a satisfactory degree of comfort in wearing and finally, yet importantly, a great aesthetic appearance, no matter what is the end use [1-3]. When the garment quality for women is defined from the weaving companies' perspective, there is a focus on the overall features that can be measured in a laboratory [4-5]. Predicting the overall suitability for designed end use and the products' success on the market can be a hard topic for fabrics and clothing manufacturers and for retailers, thus, the improving of the fabric design strategy should be a mandatory task in textile companies [3, 6-8]. A major concern within the textile value chain is to react timely to the consumer preferences and, nowadays, the sensorial comfort of any item of clothing together with the fabric quality seems to come first in the top of the consumer preferences. Regardless of the reference source and the market niche, polls about the clothing consumer lifestyle revealed that when shopping for apparel, consumers are not simply pursuing the latest fashion trends. On the contrary, they are willing to pay more for comfort, general appearance, and high-quality products, more Sensory analysis of textiles: case study of an assortment of stretch denim fabrics
