涤/棉织物同浆印花工艺发展

Progress of Printing Polyester/Cotton Fabric by One Paste

涤/棉织物具有外观挺括、耐磨、耐用、尺寸稳定、易洗快干等优点,适宜制作各种服装。目前市场上出售的涤/棉印花织物大部分采用涂料印花工艺印制。涂料印花虽然工艺简单,成本低,但成品的手感硬,色牢度差,印制时易塞网。文章综述了涤/棉织物的分散/还原染料同浆印花工艺和分散/活性染料同浆印花工艺。其中分散/活性染料同浆印花工艺具有色谱齐全、色泽鲜艳、手感较好的优点,可解决涂料印花中大块或满地印花引起的手感硬、色牢度差等问题。

Polyester/cotton fabric is suitable for making all kinds of clothing due to its advantages such as stiff touch,abrasion resistance,durability,dimensional stability,easy to wash and quick-drying,etc.At present,most of the polyester/cotton printing fabrics sold on the market are printed with pigment.Although the pigment printing process is simple and low-cost,the handle of its product is hard,its color fastness is poor,and it is easy to clog the screens during the printing process.In this paper,the printing of polyester/cotton fabric with disperse/vat dyes and disperse/reactive dyes by one paste are introduced.Thereinto,disperse/reactive dyes in one paste has the advantages of the complete chromatogram,bright color,and good hand feeling,which can solve the problems of hard hand feeling and poor fastness caused by large or all-over printing in pigment printing.
