“…The thermal conductivity method was established by the Faculty Research Laboratory and is used in common to evaluate the thermal conductivity properties [18]. Measuring the thermal conductivity is based on the transport of the heat fl ow from a warmer to cooler region, from the bottom of the apparatus to the top.…”

In the presented research, 11 different laminates were compared, 8 of them were two-layered 3 of them were three-layered laminates. The laminates that were analyzed vary by the type of face-side textile material (knitted and nonwoven textiles), density and thickness of the foam, and specific properties (higher air permeability and low-emission foam). Depending on the different types of laminates, different laminating processes are used: hot-melt, flame, and powder laminations. The purpose of the presented research is to analyze the basic characteristics of the different laminate structures. Properties that are important for these types of laminates are the number of layers, areal density, thickness, resistance to rubbing, fire resistance, water vapor permeability, air permeability, breaking force and extension, thermal conductivity, and stratification. We found that the properties of laminates were not affected by the density and thickness of the foam. Nonwovens and other laminate components do not perform because they have lower abrasion resistance and lower tensile strength than knitted fabrics as the face layer. Knit laminates have good abrasion resistance, high air permeability, and water vapor permeability. Both are self-extinguishing to the first or second mark. Three-layered laminates have lower thermal conductivity and air permeability than two-layered laminates.

“…Clothing comfort, particularly the feeling of coolness during the summer season or when engaging in sports activities, is of paramount importance for wearers. As the human body generates heat more quickly during vigorous activities, the moisture transport and water vapour transmission (WVT) properties of a garment highly influence its capability to dissipate the extra heat or water vapour from the human body to the outer environment and consequently maintain the body temperature at 37°C through perspiration evaporation [3][4][5][6].…”

Multifunction elastic warp-knitted fabrics were fabricated on a crochet machine with the use of metal composite yarns/viscose yarn and bamboo polyester/ crisscross-section polyester hybrid yarns as the front face and back face of the knitted fabric structure, respectively. We investigated the effect of the blend ratio of bamboo charcoal/ crisscross-section polyester multiply yarns on the fabric's moisture comfort properties, such as water vapour transmission (WVT), water evaporation rate (WER), and water absorbency. The results showed that blending ratio significantly influenced WVT and WER. Moreover, antibacterial activity of the elastic warp- knitted fabric was tested against Staphylococcus aureus and Escherichia coli in accordance with AATCC 90-2011. Finally, the extension- stress value curves were used to analyse the elastic stretching property, and the fabric exhibited greater breaking elongation and lower stress value in the walewise than in the weft direction.

“…Já quanto ao conforto, encontrou-se artigos referentes a tecidos sem estampas, como BROEGA e SILVA [5] que descrevem a importância do conforto no vestuário. Outros estudos como os de HAE et al [6], GORJANC et al [7], e BAJZIK [8], relacionaram o conforto térmico ao ambiente. ZHANG et al [9] discutem a aplicação de sílica em algodão para analisar os efeitos hidrofóbicos utilizando o ensaio de ângulo de contato da gota e concluí-ram que a sílica aplicada ao algodão deixa o tecido superhidrofóbico.…”

RESUMOOs avanços industriais para o setor de vestuário, ligam os desejos e as necessidades dos usuários a soluções relacionadas a aspectos da moda, da tecnologia e do conforto dos tecidos. Com o objetivo de contribuir para o desenvolvimento de processos de inovação por meio do design, o presente estudo analisa a eficácia de dois produtos hidrofóbicos de empresas do Rio Grande do Sul, o produto 1495 da Claritex e o produto 1003 da Corium. Estes produtos foram aplicados nos tecidos Dress e Sublime, ambos com 90% poliéster 10% elastano e estampados por sublimação, da empresa têxtil Santaconstancia, São Paulo. Busca-se avaliar se os tecidos perdem as propriedades hidrofóbicas após várias lavagens e se mantêm sua permeabilidade ao vapor de água, a qual contribui ao conforto térmico. Foram analisados, o processo de lavagem doméstica, os ensaios de permeabilidade ao vapor de água e o ângulo de contato da gota. Os resultados mostraram que os dois produtos hidrofóbicos analisados são eficazes, mas o produto 1003 obteve a maior média do ângulo de contato da gota após 20 lavagens. Outro resultado obtido foi que os tecidos analisados não sofreram mudanças significativas nos valores de permeabilidade ao vapor de água quando comparados aos tecidos crus, sem aplicação de estampa e sem o produto hidrofóbico.

ABSTRACTIndustrial breakthroughs for the clothing sector connect the consumers' desires and needs to solutions related to fashion and technology aspects, and the comfort of the fabrics. In order to contribute to the development of innovation processes through design, this study examines the effectiveness of two hydrophobic products from Rio Grande do Sul companies: the product 1495, from Claritex, and the product 1003 from Corium. These products were applied to the fabrics Dress and Sublime, both with 90% polyester, and 10% elastane, and printed by sublimation, from the textile company Santaconstancia. The objective is to evaluate if the fabrics lose their hydrophobic properties after multiple washings, and if they maintain their permeability to water steam, which contributes to thermal comfort. It was analyzed assays with resistance to domestic laundering, the water steam permeability and the contact angle from the drop of water. The results showed that both hydrophobic products analyzed are effective, but the product 1003 had the highest average of contact angle from the drop of water after 20 washes. Another result is that the fabrics analyzed haven't suffered significant changes in the permeability to the water steam values when they compared to fabrics without application of print and the hydrophobic product.
