[0002] Raffia is also called Wishing Rope or Love Grass. Raffia comes from Madagascar in Africa with a distant exotic and mysterious feeling. Raffia is an imported forage. Smooth and refreshing, not afraid of water and extremely strong, therefore, it is also regarded as love grass, implying that people should treat love consistently and steadfastly; raffia is often used as a weaving hat due to its strong toughness However, raffia is difficult to color, and its properties are extremely unstable after coloring, and it is easy to change color and fade after being exposed to the sun. Therefore, the invention of a dyeing method for sunscreen raffia hats can effectively promote the rapid development of raffia woven products. develop

Abstract

The invention belongs to the technical field of dyeing of straw-weaved products and particularly relates to a sun-block raffia straw hat dyeing method. The specific method comprises the steps of (1) conducting vapor treatment on weaved raffia straw hats, taking out the raffia straw hats, soaking the raffia straw hats in a dyeing agent, introducing ultrasonic waves to conduct ultrasonic treatment and putting the raffia straw hats into a magnetic field for magnetization treatment; and (2) conducting hot pressing and drying on the raffia straw hats, soaking the raffia straw hats in a sodium alginate aqueous solution, taking out the raffia straw hats and conducting hot pressing and drying on the raffia straw hats. The infiltration capacity of dyeing agent molecules is effectively enhanced. Thepolymerization capacity between the dyeing agent molecules and cellulose is improved. The raffia straw hats are dyed uniformly and thoroughly, are bright in color and extremely stable in dyeing performance, have remarkable anti-ultraviolet performance and cannot discolor after long-time sun exposure or rain drenching. The use quality of the raffia straw hats is effectively improved. The service life of the raffia straw hats is prolonged. Moreover, the anti-corrosion and anti-mildew capacity of the raffia straw hats can be further improved. Breeding of harmful bacteria is inhibited. The raffiastraw hats have not pungent smell and tangy light flower fragrance. The popularity degree of the raffia straw hats is effectively improved.
