Embodiment 1

[0018] A transparent printing process utilizing polymer polyurethane of the present invention comprises in sequence: scraping printing printing paste, pre-baking, baking, alkali treatment, washing, drying, softening finishing, and setting drying.

[0019] In the transparent printing paste process, the treatment agents used are: Qingdao Feilongyuan multifunctional enhancer NANO PU 86% (mass fraction) and Qingdao Chenxintai Luxol F-HIT 14% (mass fraction).

[0020] The printing machine pressure is 2.5KGf / cm 2 .

[0021] In the baking process, the baking temperature is 160° C., and the baking time is 90 s.

[0022] The alkali treatment process adopts 150g / L sodium hydroxide solution for 300s.

[0023] The soft finishing process adopts 3.25g / L Suzhou Liansheng smooth silicone oil 6970 and 6.75g / L Suzhou Liansheng smooth silicone oil 6973.

[0031] Selection Experiment of Transparent Printing Paste Auxiliaries

[0032] Test process: semi-finished product→scraping printing paste→drying→baking→alkali treatment→washing→drying→soft finishing→setting and drying. Under the condition of keeping other conditions uniform, the auxiliaries used in transparent printing pastes were screened. Please refer to Table 1 for the specific process.

[0033] Table 1 Transparent printing paste process

[0034]

[0035] Due to the low viscosity of the printing paste, serious penetration of the cloth surface after printing, and uneven treatment of the cloth surface, Luxol F-HIT was used to increase the viscosity of the printing paste. Through cloth sample comparison, Luxol F-HIT14% (mass fraction), printing paste viscosity 8000mpa.s, printing machine pressure 2.5KGf / cm 2 The printing effect is the best under the process conditions.

[0036] (1) 80-mesh flat screen was used for printing paste during the test.

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of transparent printing, in particular to a transparent printing process utilizing polymer polyurethane. Background technique [0002] Fabric transparent printing, also known as imitation burn-out printing, is a process that uses polyurethane resin to print on the fabric to form a translucent effect. Through certain process conditions, it can react and fix on the fabric. After washing and other soft finishing processes, Make the fabric pattern have a hazy and transparent visual effect. Since the transparent printing paste contains a variety of independent and mutually reactive components, the requirements for the preparation and storage of the printing paste are quite high. Generally, the paste for transparent printing is unstable and the process is cumbersome; and the paste and fibers cannot fully react, in order to remove the unreacted paste and make the resulting film more transparent, it must be cleaned...
