新型增稠浆EcopO-2对颜料印花产品手感的影响

Influence of novel thickening system EcopO-2 on hand feeling of pigment printed fabrics

研究和比较了新型增稠浆EcopO-2和常用合成增稠体系对颜料印花织物手感的影响,并对新型增稠体系大幅改善颜料印花产品手感的机制进行了探索。结果表明:应用新型增稠浆EcopO-2配合优质黏合剂,可以实现颜料印花产品手感的大幅改善,织物硬挺度和PhabrOmeter测定表明,印制的棉织物和丝织物其手感均接近和达到相应染料印花的水平;印浆皮膜的质量变化、EDS元素分析和TG分析表明,EcopO-2的使用对颜料印花产品手感的改善有重要作用,其基本原因在于EcopO-2增稠浆不仅具有极低的含固率,而且其小分子内相物质能在黏合剂成膜时进入皮膜起到增塑和增柔作用。

The impacts of the new thickening paste EcopO-2 and other common synthetic thickening pastes on the hand feeling of pigment printed fabrics were compared,and the mechanism by which EcopO-2 significantly improves the hand feeling of the pigment printed fabrics was explored.The results showed that EcopO-2 plus fine binder can improve the hand feeling of pigment printed fabrics significantly.The stiffness test and PhabrOmeter determination indicated that the hand feeling of the pigment printed cotton or silk using ExopO-2 was near to or reached that of cotton or silk printed with the corresponding dyes.The weight change test,EDS elemental analysis and TG analysis of the printing paste membrane showed that EcopO-2 plays an important role in the hand feeling improvement.The basic reason lies not just in the extremely low solid content of EcopO-2,but in the small molecules of its inner phase material being able to get into the adhesive film acting plasticizing and softening role.
