Abstract

The invention relates to the field of textile dyeing and particularly relates to a cold pad-batch process for preparing a grey black pure-flax fabric. The process comprises the steps: carrying out two-dipping two-rolling by using a gall nut natural dye according to a bath ratio of 1: 20 at the temperature of 20 DEG C, carrying out batching-up, and carrying out clean water washing for later use; carrying out constant temperature preserving for 30 minutes at the temperature of 40 DEG C according to a bath ratio of 1: 30 in a manner that the HAc concentration is 1g / L to 4g / L and the ferrous sulfate concentration is 3g / L to 7g / L, and carrying out water washing, soaping and baking, thereby preparing the grey black pure-flax fabric. According to the process, the natural dye is extracted from gall nuts which serve as a raw material; through a normal-temperature cold pad-batching process, the contact time of pigments and fibers is prolonged, and the infiltration performance of the pigments is improved; a grey black is achieved through mordant dyeing, and thus, the process will play a role in directing the large-scale production of plant dyed black flax fabrics.

Description

technical field [0001] The invention relates to the field of fabric dyeing, in particular to a cold pad-batch process for preparing gray-black pure linen fabric. Background technique [0002] my country has a history of thousands of years of natural pigments for coloring and fixing textiles. Since the birth of synthetic dyes in the middle of the 19th century, they have gradually replaced natural dyes because of their complete color spectrum, bright color quality, washability and light resistance, and low price. However, with the strengthening of people's awareness of environmental protection and the emphasis on health concepts, more and more attention has been paid to the side effects of some synthetic dyes on human health and the ecological environment. A large number of studies have also shown that there are more than 100 commonly used dyes that are harmful to the human body such as mutagenicity, carcinogenicity and allergy. Natural dyes have been re-examined and more and...
