Problems solved by technology

[0003] Linen fabrics have thicker fibers and larger Young's modulus, so they are more rigid and difficult to color. If you use maple leaf as a dyeing agent to dye linen fabrics, the fabrics will be harder and the handle will not be good.

Abstract

The invention discloses a linen dyeing method using maple leaf as a dyeing agent. Primarily dyed linen is heated by steam, so that, on one hand, the dyeing agent is oxidized at high temperature for color change, namely the color of the dyeing agent on linen is changed from grass green to black, and on the other hand, the effect of softening the linen is achieved, namely the linen is gradually softened under dual actions of high temperature and water vapor; low-temperature drying of the linen can promote complete oxidation of the dyeing agent and facilitates secondary dyeing; through the secondary dyeing, dyeing can be more uniform, so that appearance of accumulated marks after dyeing of the linen are avoided; anti-decoloring treatment is achieved through steam heating of the linen, so thatnot only are the effects of promoting the oxidation of the dyeing agent and preventing decolorization achieved, but also the effect of secondarily softening the linen is achieved, and thus the dyed fabric is soft in texture and is uniformly dyed.

Description

technical field [0001] The invention relates to the technical field of fabric dyeing, in particular to a linen dyeing method using maple leaf as a dyeing agent. Background technique [0002] Flax, also known as crow's hemp and flax, can be divided into three categories: fiber, oil, and fiber and oil, all of which are annual herb plants. Because of its good hygroscopicity, quick moisture conduction and relatively small diameter, it is one of the main fiber materials for spring and summer clothes. Usually, the cloth woven from flax fiber is called flax fabric. The flax fiber exists in the bast tissue of the hemp stem. After soaking and degumming to remove part of the gum, the adhesive fiber bundles are partially loosened, and then processed into "beaten hemp" by rolling and beating hemp, which is 10 to 20 single Craft fibers composed of fibers. Linen cloth is woven by twisting linen fibers. The surface is not as smooth as chemical fiber and cotton cloth, but has a vivid con...
