The research contains the analysis of main principles, making the «fast-fashion» concept successful, reveals the key criteria, according to which the brands are classified as «fast-fashion». The present publication reflects the core principles of fashion business entities activity within the «fast-fashion» segment and specifies the criteria of singling out the target consumer audience. The concept under consideration is viewed as a factor of fashion business vector transformation. The research claims that within the high-responsiveness concept the fashion product is being developed and manufactured based on mass-market customer demand, its attitude towards fashion changes and life-style, rather than designer approaches.

The studies carried out have shown that chitosan possesses high cross-linking properties enabling it to be used for intensifying the process of chrome tanning thus decreasing the consumption of chromium salts and, at the same time, increasing the shrinkage temperature of the leather. IRspectroscopy has shown that interaction between chitosan and collagen is likely to involve oxygen from the C-O-C groups, hydroxyl groups and amine groups of chitosan and the functional groups of collagen, which form bonds of different types. On increasing the consumption of chitosan in treating hides there is rise in the maximum destruction rate temperature for dermal collagen, which was obtained by DTA for chitosan-chromium-tanned leather. The optimum consumption of formic chitosan is 2% of the hide mass at a chromium level of 0.5% of the hide mass calculated as chromium oxide. In this case, the necessary plasto-elastic properties of the leather are provided, and the shrinkage temperature is 92°C. Source

The paper is devoted to the experimentally investigations of the dimensional properties such as fabric density variations and dimensional constants parameters of the nine types single tuck stitches. The structures repeat at height consists of combination of two courses: plain and plain tuck stitches with different stitch repeat at the width, Rb. The fabrics are produced by the flat bed-knitting machine 10 gauge from j the 31.2 tex half-wool yarn. All measurements of the structures parameters are made on the fabrics after four cycles of washing in a domestic washing machine. Source
