Abstract
A set of consumer properties of hydrophobicized nutria fur velour obtained with the use of alkenmalein-acrylsyntane composition has been studied. Components of this composition included alkenmalein polymer, polyacrylic polymer and synthetic tanner. The process of filling and hydrophobicizing nutria fur velour was carried out at pH of the working solution of 6.8‒7.0, temperature of 40‒43 °С during three hours and completed at a pH of 3.8‒4.0.Hydrofobicized nutria fur velour was obtained from raw materials with low hair quality, heterogeneous structure in different topographical areas and low density but with satisfactory physical and mechanical properties of the skin tissue.Influence of the component ratio of the filling and hydrophobicizing composition on the physicochemical properties of fur velour was established. Specifically, the following characteristics have been studied: total thermal resistance, dynamic water wetting, water drop absorption, wetting angle, wetting, vapor permeability, air permeability, etc.Optimal component ratio of the alkenmalein-acrylsyntane composition has also been established which ensures formation of a modified nutria fur velour with a set of improved consumer properties compared with the sheepskin velour. In particular, reduction of the total thermal resistance and vapor permeability of the hydrophobicized nutria fur velour observed during hydroprocessing was less: 9.7 and 1.7 times, respectively, than that of the sheepskin velour. At the same time, aesthetic indicators of the nutria velour (coloristic design and quality of leather dressing were also higher (by 39‒41%) than those of the sheepskin velour.The obtained results from hydrophobicizing fur velour with a set of required consumer properties indicate the possibility of expanding the range of products made from fur raw materials with poor-quality hair but satisfactory physical and mechanical indicators of skin tissue. Fur products manufactured from hydrofobicized nutria velour will be suitable for wearing under conditions of high humidity.
Highlights
Present-day fur production involves fabrication of a wide range of furs and fur coat materials including velour
Considerably larger changes in deformation indicators of Sheepskin fur velour (SFV) skin tissue and especially residual elongation are explained by its greater water sensitivity connected with increased hydrophilicity of its structure
Proceeding from the discussed set of essential consumer properties, the hydrophobicized nutria fur velour obtained by the developed technology can be used as an effective material for replacing sheepskin fur velour in the manufacture of water-resistant wear products
Summary
Present-day fur production involves fabrication of a wide range of furs and fur coat materials including velour. Taking into consideration the shortage of such raw materials in Ukraine [2], there is an objective necessity and urgency in a search for other types of fur raw materials with a corresponding set of consumer properties. In this regard, male nutria skins with low-grade overhair unsuiTable for the manufacture of fur material are of interest. Male nutria skins with low-grade overhair unsuiTable for the manufacture of fur material are of interest They can be effectively used in production of fur velour after overhair epilation and improvement of physical and mechanical properties of the skin tissue by applying new chemical filling materials followed by hydrophobicizing
