Transparent printing technology through macromolecule polyurethane

The invention discloses a transparent printing technology through macromolecule polyurethane. Aiming at the problems of more independent components in pure cotton fabric transparent printing paste andcomplex technology, the technology comprises the following steps: scarping printing paste, preliminary drying, baking, performing alkali treatment, water washing, drying, performing softening finishing and performing setting drying; in the step of scarping printing paste, a treating agent adopts multifunctional improvers NANO, PU and Lutexal F-HIT. The technology has the advantages that the fabric printing design is high in transparency, obvious in wrinkling, exquisite, soft, moist and soft in hand feeling, and the fabric property is furthest reserved. 本发明公开了种利用高分子聚氨酯透明印花工艺，针对纯棉织物透明印花印浆中独立组分多，工艺繁琐的问题，包括以下步骤:刮印花浆、预烘、焙烘、碱处理、水洗、烘干、柔软整理、定型烘干；所述的刮印花浆步骤中，处理剂为-多功能增进剂NANO PU和路得素F-HIT。采用该透明印花工艺，织物印花花型透明度高、起皱较明显，手感润滑、细腻、温润、柔软，织物性能得到最大程度的保留。
