Sobre IBD

Este livro é sobre o poli(tereftalato de etileno), geralmente referido como PET, processamento químico particularmente no que diz respeito à melhoria das suas características hidrofílicas. A hidrofilicidade é exigida principalmente em quase todas as peças de vestuário formais e casuais, mas o poliéster original não possui essa importante propriedade. Portanto, para melhorar as propriedades hidrofílicas, é altamente necessário tratar os substratos têxteis de poliéster com alguns produtos químicos não nocivos. Assim, também neste caso, o PET foi tratado com álcool polivinílico (PVA) em meio alcalino. Devido a este tratamento, o PET está a melhorar do comportamento hidrofóbico para o comportamento hidrofílico. Este PET tratado com PVA apresentou uma absorção de água muito boa, caráter de absorção e, assim, levou à melhoria das características de tingimento. Portanto, estes materiais têxteis de PET tratados com PVA seriam bastante úteis para o uso de muitas peças de vestuário normais do dia a dia e aplicações semelhantes adequadas para os utilizadores finais.
