Denim clothing styling liquid, preparation method thereof, and use in ultraviolet photocatalytic styling 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 styling liquid and a preparation method thereof, and its use in an ultraviolet light photocatalytic styling finishing method, which belongs to the technical field of textile additives and textile finishing. Background technique [0002] Since LeviStrauus invented the first pair of denim jeans in the 19th century, denim clothing has been loved by consumers for its rough, simple, natural and natural, comfortable and wear-resistant characteristics, and has become a major consumer product of people. The amount is considerable. Denim finishing is a key process that gives denim garments a unique style. It determines the added value of a denim garment and is also an effective means to increase the added value of denim products. The finalization of denim garments (called denim crumpled in the industry) is one of the important aspects of denim finishing. At present, in terms of crumpling of ready-made denim garments, the t...

Chinese Patent Publication No. CN101768868A, the publication date was July 7, 2010. The title of the invention patent is "a resin setting liquid and a denim creasing process using the resin setting liquid". The application discloses a water-based polyacrylate 50 -150g, photosensitizer 0.1-1.0g, fiber protection agent 5-25g, penetrating agent 1-5g are denim garment styling liquid, and the ultraviolet light curing process is used to realize the wrinkle finishing of denim garments. The cross-linking and curing of water-based polyacrylate can cover the surface of the fiber and play a role in shaping. The disadvantage is that the denim clothing after shaping has poor hand feeling, and the shaping resin may fall off in the subsequent washing process, which affects shaping. 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
