Abstract

The invention provides a dyeing and shaping process for sunflower leaves. The process comprises the steps of (1) removing leaf stems of sunflower leaves, only keeping the leaves, (2) separating the leaves from each other and respectively hanging the leaves on a bracket, (3) adding dye into heated water for stirring and dissolving to obtain dye liquor, (4) heating the dye liquor, taking the fixed leaves to be vertically immersed in the dye liquor and continuously boiling for a certain time, (5) removing the dyed leaves and cooling and soaking the leaves in water, and (6) airing the leaves subjected to fixation in natural sunlight and then carrying out double-sided clamping and scalding. Each blade is hung on a bracket, and the blades are separated and fully contacted with dye liquor so as to carry out uniform dyeing. The high Wen Zhukui leaves can make the sunflower leaves absorb water and expand, and the dye solution permeates into the sunflower leaves, so that the color vividness of the sunflower leaves is enhanced, and the dye adsorption rate is improved. The oil wax on the surface of the sunflower leaves is separated from the sunflower leaves and floats on the liquid surface in the high-temperature boiling process. The double-sided clamp ironing can not only keep the color of the dyed sunflower leaves fixed, but also shape the sunflower leaves to keep the luster of the sunflower She Youliang.

Description

Sunflower leaf dyeing and shaping process Technical Field The invention relates to the technical field of dyeing, in particular to a sunflower leaf dyeing process, and more particularly relates to a sunflower leaf dyeing and shaping process. Background The sunflower art refers to an art product made from sunflower leaves. The Xinhui sunflower art refers to the general term for sunflower products produced in the Guangdong Xinhui region. The Chinese painting is synthesized with Guangzhou dental engraving, embroidery, paper cutting of Buddha mountain, ceramic art, zhaoqing Duanxi inkstone, yangjiang lacquer and new Mao Long pens, and is a Guangdong folk eight major traditional technology, and the second batch of Chinese 'national non-material cultural heritage directory' is selected in 2008. The Xinhui sunflower art product is a living apparatus which is indispensable for people living in Xinhui areas. The variety of the Xinhui sunflower art products is various and nearly 500, and can be divided into three categories, namely a sunflower fan category, a sunflower braiding container and a sunflower braiding mat category according to different use functions. Early sunflower braiding products are rarely decorated by colors, raw materials and finished products are not dyed, most of the products are made of the primary colors of dry Chinese fan palm leaves, and the products are light yellow, yellow white and the like so as to present a plain sunflower art product. However, with the pursuit of various colors, people are not satisfied with the primary colors of yellowish, yellowish-white, etc., but hope to obtain sunflower braids with more colors. Thus, a small amount of dyed artware appears in the 80 s of the last century, but the treatment process is not mature, the product has no luster, and only nylon, cloth and other materials can be added into the artware in the subsequent process, so that the color of the product is increased. . In addition, since a layer of natural oil wax is generally present on the surface of the sunflower leaf, the presence of the oil wax makes it difficult for the dye to adhere to obtain the sunflower leaf with gorgeous color. In addition, if the sunflower leaves are improperly treated after dyeing, the sunflower leaves become soft and lose gloss, and the glossy gloss of the sunflower leaves is difficult to maintain, so that the visual effect of the prepared sunflower braid product is not good. Disclosure of Invention Based on the above problems, the present invention aims to provide a process which not only can dye the sunflower leaves to contain rich colors, but also can shape the sunflower leaves to keep the gloss of the sunflower She Youliang. In order to achieve the above purpose, the invention provides a dyeing and shaping process for sunflower leaves, which comprises the following steps: (1) Pretreatment of sunflower leaves Removing leaf stalks of the sunflower leaves, and only keeping the leaves; (2) Sunflower leaf fixation Separating each blade and hanging the blades on a bracket respectively; (3) Preparing dye liquor Adding dye into the heated water, stirring and dissolving to obtain dye liquor; (4) Dyeing After heating the dye liquor, taking the fixed blades to be vertically immersed in the dye liquor and continuously boiling for a certain time; (5) Color fixation Removing the dyed blades and cooling and soaking the blades in water; (6) Shaping And airing the blade subjected to fixation in natural sunlight, and then carrying out double-sided clamping ironing. In the technical scheme adopted by the invention, the hard leaf stems are removed, and soft leaves are reserved for dyeing. Each blade is hung on a bracket, then is vertically immersed in the dye liquor and is continuously boiled for a certain time, and the blades are separated and fully contacted with the dye liquor, so that uniform dyeing is carried out, and the generation of color spots is avoided. And in the process of boiling the dye liquor, the high Wen Zhukui leaves can make the sunflower leaves absorb water and expand, so that the dye solution permeates into the sunflower leaves, the color vividness of the sunflower leaves is enhanced, and the dye adsorption rate is improved. The oil wax on the surface of the sunflower leaves is separated from the sunflower leaves in the high-temperature boiling process and floats on the liquid surface, and finally, the sunflower leaves can be thoroughly separated through cooling soaking and double-sided clamping scalding so as to fix the colors. The double-sided clamp ironing can not only keep the color of the dyed sunflower leaves fixed, but also shape the sunflower leaves to keep the luster of the sunflower She Youliang. As a technical scheme of the invention, the dye is added after the water in the step (3) is heated to 35-55 ℃. As a technical scheme of the invention, the blade is immersed when the dye liquor is heated to 70-85 ℃. As a technical scheme of the invention, the cert
