The use of Metal-Organic Frameworks (MOF) such as HKUST-1 in textiles is an alternative with regard to the development technologies that are increasingly seeking for functionalities, mainly fields health and hygiene, named biofunctional fabrics. However, application MOF under surface wool fiber can lead a low durability finish due its fixation. Thus, this project aims perform direct synthesis HKUST fiber, so product good washing be obtained. purpose study was incorporate metal-organic...
ABSTRACT Antimicrobial cotton was developed with silver zeolites (SZs). Three different application approaches for the surface functionalization were followed: (1) SZ alone, (2) combined chitosan film, and (3) chitosan–zeolite (CS–SZ) composites previously synthesized by a gelation process sodium tripolyphosphate. All finishes applied to textile materials through conventional pad–dry–cure processes, obtained results then compared. The resulting characterized Fourier transform infrared...
The development of antimicrobial cotton fabrics using chitosan/silver-zeolite film has been investigated in the present work. was applied to 100% fabric a common pad-dry-cure technique and citric acid used as crosslinking agent. resulting were characterized through infrared spectroscopy (FTIR), contact angle scanning electron microscopy with X-ray microanalysis (SEM/EDS). activity assessed viable-cell counting method materials showed against S. aureus T. rubrum. textile performance analysed...
The use of cyclodextrins in textiles for the development biofunctional fabrics represents an interesting alternative advancement dental, medical, and hospital materials. Cyclodextrins can interact with chemical groups present cotton fibers, leading to formation a nanostructured surface specific functional properties, including antibacterial activity. Although there are numerous textile finishes, methylene blue as cyclodextrin host molecule photodynamic applications materials remains be...

Participaram 565 alunos 3° ao 9° anos do ensino fundamental público estado Paraná. Utilizou-se Escala Avaliação Estilos Aprendizagem, com 80 itens, aplicada coletivamente. fatorial, por componentes principais e rotação varimax, indicou quatro Dimensões para a escala. As se agruparam seguinte...
The expectations regarding the functional characteristics and performance of textile products have been steadily increasing.In this sense, multifunctional materials with thermoregulatory antimicrobial properties were developed using different finishing strategies.For purpose, through processes, application microcapsules phase change materials, mPCM, combined agents natural origin, was carried out.Specifically, zeolites doped silver, composites chitosan TiO 2 , in combinations, used.The...
The development of materials with multiple functionalities is a market imperative that places new challenges on textile processing. purpose this study was to establish the conditions obtain cotton material comfortable, self-cleaning and antimicrobial properties. For purpose, microcapsules phase change (mPCM) titanium dioxide nanoparticles (TiO2 NP) were applied. resulting fabrics characterized resource infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), contact angle...
Metal-organic frameworks are crystalline nanostructures formed by a metal interspersed an organic binder. These metal-organic materials examples of nanomaterials applied to textile material in search new functionalized textiles. Cotton is cellulosic fiber great commercial importance, and has good absorption capacity breathability; however, due these characteristics, it susceptible the development microorganisms on its surface. This work aims analyze how direct synthesis HKUST-1 cotton fabric...
Este artigo discute sobre a prática da construção de protótipos na indústria do vestuário. O protótipo refere-se à um modelo que está em processo planejamento e teste para ser comercializado. Atualmente forma mais difundida é realizando efetiva das peças, porém existe disponível no mercado softwares realizam essa atividade virtualmente. Assim, esse estudo tem como objetivo investigar o por meio software CAD 3D prototipagem vestuário técnicas tradicionais manuais utilizadas atualmente fim...
A presente pesquisa objetivou investigar as estrategias de ensino utilizadas pelos professores, bem como bases teoricas no processo.
