Polyester waste is the dominant component of the clothing industry waste stream, yet its recycling in this industry is rarely addressed. This paper proposes using polyester cutting waste as an insulation blanket for roofing and buildings' internal walls in order to reduce environmental pollution. The designed textile structures used waste cuttings from different polyester fabrics without opening the fabric to fibre. Thermal insulation, acoustic insulation, fire resistance and biodegradation of the new insulation structure were investigated and compared to commercial insulation materials. Standard investigation methods were modified to fit the samples voluminous nature. The coefficient of thermal conductivity ranged between 0.0520 and 0.0603 W/mK. The achieved sound absorption with NRC ranging from 54.71 to 74.77%, surpassing standard commercially used insulators. The insulating structure did not conduct flame, the radius of impaired place was 1.60-2 cm while the depth was 0.4-1.3 cm, and showed lack of biodegradability, with loss of mass ranging from 0 to 0.3%.

Social media has become a powerful communicating tool for the fashion industry, providing an instant, democratic, user-generated dissemination of fashion trends, particularly with the younger generations. Image-centred social media, such as Instagram are particularly well adopted for fashion communication. This research aims to investigate the role of Instagram on the dissemination of fashion trends amongst Generation Z. The research used an electronic questionnaire distributed to 120 participants, aged 16 to 23 years. A commercially available tool for measuring the reach of global and local fashion influencers was used to comprise a list of influencers used in the research. Cluster analysis was used to identify Instagram influencers impacting fashion and the use of Instagram as a fashion information channel.

Wines of three different grape varieties, Vranec, Cabernet Sauvignon and Merlot were examined for their characterisation in terms of anthocyanin and chromatic profiles, total polyphenols and antioxidant potential. Total, monomeric, polymeric and copigmented anthocyanins were determined by spectrophotometry and the individual anthocyanin compounds were quantified using HPLC-DAD. Chromatic profile was evaluated according to colour density, hue, % red, % blue, % yellow and brilliance (% dA). The established data were submitted to analysis of variance and principle component analysis in order to evaluate their potential for differentiation of wines according to variety and vintage. Vranec wines have shown distinctive characteristics, with the highest content of anthocyanins and values of colour intensity, % red and % dA, compared to the other two studied varieties. The content of petunidin-3-glucoside, peonindin-3-glucoside and anthocyanin acetates were established as possible markers for differentiation of Vranec wines from Cabernet Sauvignon and Merlot wines. However, none of the assayed parameters could be used for differentiation of Cabernet Sauvignon from Merlot wines. It was observed that wine age limits successful classification of the wines by variety according to anthocyanins. The chromatic parameters allowed distinguishing of young (aged up to 1 year) from old Vranec wines

Woven fabrics are materials of a sophisticated structure. Basic structural parameters, the raw material, linear density of warp and weft yarn, number of yarn twist, warp and weft density, warp and weft crimp, as well as weave contribute to the obtained properties of the fabric. Certain basic parameters of the fabric can be controlled directly either during the preparatory processes or during the weaving process itself. There are some important structural parameters, however, for which no direct quantitative controls exist. Since all structural parameters are closely interdependent, the lack of direct control results in an imperfect control of the fabric structure. The subject of the investigation was how small variations in semi-worsted wool fabric constructional parameters influence the air permeability, and to which extent they can be controlled in the design process and weaving of fabrics. The experiment showed that yarn count, warp and weft density and warp and weft crimp are highly interrelated, leading to small variations in the fixed sett. The statistical significance of small variations in the groups of fabrics was confirmed by the analysis of variance. The analysis confirmed that there were no differences in mass, although all other structural parameters differed. Additionally, a post-hoc Bonferroni test showed that the structural parameters of the group of fabrics, which has a practically balanced structure, are always different to those of groups g2 and g3. Fabric alternations done on the same warp, in such a manner to achieve the same mass per square meter, showed that the change in weft yarn count and weft density influenced the fabric structure as a result of the crimp interchange. However, there was not a statistically significant difference among the three groups of fabrics when tested for air permeability.

By its origin, textile waste can be divided in two broad categories: post-consumer waste and postindustrial waste generated during the manufacturing process. The division of the clothing supply chain between developed consumer markets and developing countries where apparel production capacities are outsourced implies that post-consumer waste is present in the former countries, whereas the later generates more post-industrial waste. The purpose of this exploratory study was to determine how the attitudes of top management towards managing apparel cuttings waste influence their willingness to introduce apparel waste sorting. The proclivity to sort apparel cuttings was strongly influenced by two key factors-the ease and costs of introducing sorting operations and impediments to sorting such as lack of workforce, technology or market. Combining these two factors leads towards negative attitudes to introducing apparel sorting. Perception of impediments in the process of sorting leads towards negative attitudes regarding the ease of introducing sorting operations; however, it does not influence adversely the proclivity to sort.

In this paper, the thermophysiological characteristics of low weight knitted polyamide and polyamide/elastane fabrics for pantyhose differing in terms of filament count were studied. Alambeta and Permetest devices were used to measure the thermal conductivity, thermal resistance, thermal absorptivity, evaporative resistance and relative water vapour permeability. The results indicated that fabrics made of finer filaments have lower thermal conductivity, thermal resistance, thermal absorptivity and evaporative resistance values.

In Macedonia, as a country with a developed apparel industry, a significant amount of pre-consumer textile waste is generated, more precisely apparel cutting waste. The aim of this paper is to make an accurate estimate of its quantity, as well as the characterization based on the raw material composition as a prerequisite for its further handling. Before any recycling initiative for textile waste, an analysis should be made of whether its quantity and quality can ensure the continuity of the recycling process. The analysis shows that the amount of apparel cutting waste is a fairly constant value (in the period from 2009 to 2014 an average of 3,377 tons of apparel cutting waste was generated annually). The waste from cotton and cotton blends is most common. Despite the constant annual amount of apparel cutting waste and numerous reasons for its recycling, almost all this waste ends in landfills.
