The range of active dyes used for dyeing materials made of natural plant fibers includes about a thousand brands belonging to more than 50 groups all over the world. Among them, bifunctional active dyes are of research and practical interest. They allow to obtain intense and durable bright color scheme due to their chemical specificity. Also they save not only the dye itself, but a number of additional textile auxiliary substances, which in turn is favorably affects the environmental performance of the dyeing process. The authors present in the article the analysis of experimental data, which make it possible to obtain or verify chemical, physicochemical and coloristic indicators of the properties of mono-, bi- and polyfunctional active dyes. Conclusions are made on the dependence of these indicators in the process of dyeing textile materials according to several technologies most often used in finishing production.

The aim of the study is the introduction of elements of entrepreneurial creativity into the university learning process to form a project team, which consists of students from different areas of specialization. The method of a business game is used, when students, preparing the collaborative graduation qualification work, find themselves in a modulator of real contradictory relations between the specialists of an enterprise: technologists, designers, managers and economists. The development of the project business model according to the method of A. Osterwalder recreates the professional situation of the comprehensive solution of production problems at an enterprise. The results of the study show an increase in the synergy of scientific, technological and entrepreneurial creativity of students. As a result of project education at university, students demonstrate the acquired soft skills, which ensure successful participation in the work process and high productivity; they experience the excitement and show higher results of their collaborative graduation qualification work. Graduation qualification work acquires the features of a startup and has higher characteristics for introducing goods and services in the market. The presentation of the collaborative graduation qualification work reproduces the real situation of the evaluation of innovative idea prospects, an idea development plan and a team of likeminded people. The experience of participating in the business model development after the request of partners of an entrepreneurial university increases the competitiveness of graduates in the labour market.
The article defines the need for comprehensive research on the justification and development of requirements for this type of product on the part of both today’s consumer and production. As a result of such studies, it is necessary to establish indicators for a comprehensive assessment of school uniform providing a high level of its quality, as well as physiological and psychological comfort to the consumer. The study analyzes the opinions of customers and the product range in retail outlets in Moscow that specialize in sales of school uniforms. It was found that 40% of respondents had serious difficulties in purchasing school uniform kits. It is especially difficult to choose clothes for thin, low stature, and stout children having a body constitution significantly differing from the typical standard. Besides, the fabric properties and model designs do not fully meet the requirements of consumers. The information collected during the research has shown the presence of unsatisfied demand of a large group of consumers of school uniforms and indicated the need for additional research to take into account physiological, hygienic, psychological, ergonomic, aesthetic, and anthropological factors, as well as ensuring the quality of fabrics, and implementing image of school children when creating a school costume.
