Jeans garment shaping liquid as well as preparation method and application thereof in ultraviolet light photocatalytic shaping and finishing method

Abstract

The invention provides a jeans garment shaping liquid as well as a preparation method and an application thereof in an ultraviolet light photocatalytic shaping and finishing method and relates to a jeans garment shaping liquid. The jeans garment shaping liquid comprises the following components in percentage by weight: 5.0-15.0 percent of polycarboxylic acid, 3.0-9.0 percent of sodium hypophosphite, 0.1-2.0 percent of Fe<3+>doped nanometer titanium dioxide, 1.0-5.0 percent of penetrating agents, 2.0-5.0 percent of formaldehyde-free environmentally-friendly stiffening agents, 3.0-5.0 percent of smooth brighteners and 59.0-85.9 percent of water. The invention also relates to the jeans garment ultraviolet light photocatalytic shaping and finishing method by adopting the shaping liquid, which comprises the following steps of: carrying out plasma radiation treatment on a part of a jeans garment required to be shaped, spraying the shaping liquid onto the treated part of the jeans garment, pre-drying on a drying tunnel-type drying oven and crinkling the treated part of the jeans garment; then carrying out photocatalytic shaping on the treated parts; and finally washing and drying. The method is high in catalytic efficiency, is environmental-friendly and energy-saving and is high in production efficiency. The finished jeans garment is durable, is good in shaping effect and good in handfeel and gloss, is environmental-friendly and generates no formaldehyde emission.

Description

technical field [0001] The invention relates to a denim clothing shaping liquid and a preparation method thereof, as well as its application in an ultraviolet photocatalytic shaping finishing method, which belongs to the technical field of textile auxiliaries and textile post-finishing. Background technique [0002] Since Levi Strauus invented the first pair of twill jeans in the 19th century, denim clothing has won the favor of consumers for its rough, simple, natural and unrestrained, comfortable and wear-resistant characteristics, and has become a major consumer product for people. The demand is considerable. Denim finishing is a key process to give denim clothing a unique style, determines the added value of a denim clothing, and is also an effective means to increase the added value of denim products. The shaping of denim garments (industrially known as denim creasing) is one of the important links in denim finishing. At present, in terms of denim garment wrinkling, t...

Chinese Patent Publication No. CN 101768868A, published on July 7, 2010, the title of the invention patent is "a resin setting liquid and denim creasing process using the resin setting liquid", the application discloses the use of water-based polyacrylate 50-150g, photosensitizer 0.1-1.0g, fiber protection agent 5-25g, penetrating agent 1-5g are denim garment styling liquid, using ultraviolet light curing technology to realize denim garment wrinkle finishing, its mechanism is to use photocatalysis Initiate the cross-linking and curing of water-based polyacrylate, cover the surface of the fiber, and play a role in setting the shape. Stereotype Persistence

[0004] Although the development of environmentally friendly denim garments has been widely valued, there are not many photocatalyzed environmentally friendly denim garment liquids and finishing methods that can be used in practice; so far, no method for doping Fe 3+ Nano-type titanium dioxide as photocatalyst, environmental protection and aldehyde-free polycarboxylic acid, etc. as denim clothing sizing liquid and its sizing finishing method to prepare environmental protection denim sizing clothing
