Abstract

The invention provides a production technology of photochromic umbrella fabric. The production technology comprises the following steps: firstly, preparing coating printing paste; secondly, printing:carrying out photochromic printing on the fabric subjected to coating finishing by using rotary screen printing equipment; thirdly, drying: enabling the printed fabric to enter a dryer and then dryingat 100 to 120 DEG C for 30 to 120 seconds; fourthly, carrying out coating finishing; fifthly, carrying out coating finishing: finishing an outer coating of the fabric on a coating machine by using anouter coating adhesive and drying at 110 to 130 DEG C for 30 to 120 seconds. The formula of the outer coating adhesive is prepared from the following components in parts by weight: 60 to 70 parts ofsolvent type PU adhesive or PA adhesive, 0.5 to 1.5 parts of bridging agent for the coating and 7 to 9 parts of organic solvent; during the preparation of a coating adhesive, firstly, carrying out mixed dispersing on the bridging agent for the coating into the solvent type PU adhesive or PA adhesive and adding the bridging agent for the coating for uniform mixing when the viscosity of a mixture reaches 5000 to 10000mpa. s. According to the production technology disclosed by the invention, by adopting an inner coating and an outer coating, the defect that the discoloration effect of the fabrictreated by an existing production technology for outdoor fabric has short service life is overcome.

Description

technical field [0001] The invention relates to the field of textile dye finishing, in particular to a production process of photochromic umbrella cloth. Background technique [0002] Outdoor products such as tents, umbrellas, and car covers are fast-moving consumer goods with a large number of users and a huge market. With the gradual popularization of domestic outdoor sports and tourism activities, the gradual change of people's daily consumption concept will further expand the market for outdoor products. At present, the entry threshold of the outdoor products industry is relatively low, and product homogeneity competition is more obvious. Conventional umbrella and tent fabrics only have the most basic rainproof function, ignoring more subdivided functional requirements, such as: sunshade and sunscreen, anti-ultraviolet rays, beautiful appearance, metallic luster effect, etc. The function of outdoor products has gradually changed from a single rainproof and windproof fu...
