Tratamento em plasma de tecido 100% Aramida para análise de molhabilidade
In order to increase the hydrophilicities and to improve dyeability, poly(ethylene terephathalate) (polyester) fabrics were treated in low pressure and temperature plasma. Different plasma atmosphere were used in this work, leaving the gas type (oxygen, nitrogen, methane and hydrogen) as plasma va...

Foram usadas as técnicas de arraste vertical e MEV (microscopia eletrônica de varredura) para analisar as amostras. As amostras tratadas em plasma de O2 e N2 apresentaram uma melhoria substancial na hidrofilidade, a qual foi atribuída à formação de rugosidade na superfície das fibras. 2021-12-07T17:31:30Z 2021-12-07T17:31:30Z 2008-01-19 article FREITAS, D.; FERREIRA, T.R.; COSTA, Thercio Henrique de Carvalho; FEITOR, Michelle Cequeira; BEZERRA, Clovis de Medeiros; ALVES JUNIOR, Clodomiro.

| description |
In order to increase the hydrophilicities and to improve dyeability, poly(ethylene terephathalate) (polyester) fabrics were treated in low pressure
and temperature plasma. Different plasma atmosphere were used in this work, leaving the gas type (oxygen, nitrogen, methane and hydrogen) as
plasma variables, other parameters like pressure, exposure time, voltage and current were not variables in the process. After plasma treatment,
the properties of the fabric, including surface morphology and chemical alteration, were investigated. The polyester fabrics treated with different
plasma gases exhibited different morphological changes. The capillary method was applied to evaluate the improvement in water uptake of polyester
fabrics, which indicated a good wettability to all atmospheres used in this work, except for a mixture containing methane, hydrogen and nitrogen |
