Problems solved by technology

[0004] The main raw material for the production of grass cloth is the manual production of hemp farmers. In order to maintain the full ecological state of the yarn count, the yarn count fiber is not damaged, so the yarn count is relatively hard; Some are densely woven, some are thinner, some are thinner, some are thicker, resulting in uneven cloth surface; traditional dyeing uses chemical dyes or a combination of chemical dyes and a small part of plant dyes, not only the products are The coloring rate, coloring rate and color fixing rate are all affected, and the production efficiency is not high; especially in autumn and winter, the natural sunshine time is insufficient, the product coloring is uneven, the production time is long, and the production capacity is reduced

Embodiment 1

[0037] Grind the yellow Gardenia jasminoides of the traditional Chinese medicine until the particle size passes through a 90-120 mesh sieve, soak in clean water for 90 hours, the volume ratio of clean water to raw materials is 10:1, then filter to remove impurities, and seal and store until use.

[0038] Soak the grass cloth gray cloth in alkaline water with a mass percentage of 3-5%, then pick it up and put it in a sealed container for natural fermentation for a week, pull it out and wash it, and use a solution mixed with clean water and 1% sulfuric acid for cleaning. Then put it into the equipment for scouring for about 2 hours, then bleach after scouring, add an appropriate amount of hydrogen peroxide during bleaching, wash again after bleaching, remove the attachments on the gray cloth, put the prepared vegetable dyes into the dyeing machine, and then Put the washed linen into the dyeing for the first time. After dyeing, add a color-fixing agent for fixed washing, and then...

Embodiment 2

[0040] Soak saffron, the dried raw material of traditional Chinese medicine, with clear water for 140-170 hours, the volume ratio of clear water to raw material is 100:1, then filter, and the filtered juice is sealed and stored in a crockery for later use. The juice prepared from saffron can be sealed with a crock to prolong its shelf life.

[0041] Soak the grass cloth gray cloth in alkaline water with a mass percentage of 3-5%, then pick it up and put it in a sealed container for natural fermentation for a week, pull it out and wash it, and use a solution mixed with clean water and 1% sulfuric acid for cleaning. Then put it into the equipment for scouring for about 2 hours, then bleach after scouring, add an appropriate amount of hydrogen peroxide during bleaching, wash again after bleaching, remove the attachments on the gray cloth, put the prepared vegetable dyes into the dyeing machine, and then Put the washed linen into the dyeing for the first time. After dyeing, add a co...

Embodiment 3

[0043] The fresh fruit raw material persimmon is crushed to pass through a 90-120 mesh sieve, and then filtered, and the filtered juice is stored in a cold storage for later use. When using the dyed juice, it needs to be used in the same volume ratio as clean water, and the volume ratio is 1:2. The juice prepared from persimmon, a fresh fruit raw material, must be refrigerated in a cold storage to prolong its shelf life. The filtered slag can also be soaked in clean water for 50-70 hours, and then filtered. The volume ratio of slag to clean water is 1:1. The juice obtained after filtration is also used for dyeing.

[0044] Soak the grass cloth gray cloth in alkaline water with a mass percentage of 3-5%, then pick it up and put it in a sealed container for natural fermentation for a week, pull it out and wash it, and use a solution mixed with clean water and 1% sulfuric acid for cleaning. Then put it into the equipment for scouring for about 2 hours, then bleach after scouring...

Abstract

The invention provides a pure natural plant dyeing process of a full-manual natural grass cloth. The process comprises the following steps of 1, preparing dyeing liquid through raw materials; sealing and storing; 2, soaking a grey grass cloth in water containing soda; transferring into a sealing container to naturally ferment for one week; 3, pulling out the cloth and cleaning through clean water and sulfuric acid; transferring into equipment to boil off; bleaching after boiling off; cleaning to remove impurities on the grey cloth; 4, adjusting the dyeing liquid; pouring into a dyeing machine to dye for the first time; and 5, adding a dye-fixing agent to the dyeing machine for solid wash, dyeing for the second time, drying after dyeing; arranging, sizing, and warehousing. According to the pure natural plant dyeing process of the full-manual natural grass cloth, gardenia jasminoides, coptis chinensis, saffron crocus, isatis root, persimmon and other plants are used for dyeing; the made clothes or household goods are soft, draped, straight, comfortable, antibacterial, health-care, warm in winter and cool in summer, high in wrinkle resistance and outstanding in air permeability, and have the effects of dissipating heat and clearing damp. The full-manual natural grass cloth is lightweight and anti-mildew, and is an outstanding pure natural green and health care fabric.

Description

technical field [0001] The invention belongs to the field of fabric dyeing technology, and in particular relates to a pure natural vegetable dyeing technology of fully manual natural linen. Background technique [0002] With the progress of society, the development of economy, the standard of living is gradually improved, the awareness of health and environmental protection is gradually enhanced, and people pursue a higher quality of life. Green products and green consumption have become a new trend in the textile industry. The hemp textile fiber with the longest history, known as the "fiber queen", has become one of the natural fibers vigorously developed by the textile industry. Because hemp fiber has functions such as moisture absorption, ventilation and antibacterial, and the product style has a sense of fashion, people's awareness of hemp products is gradually increasing, and the future development space of hemp products will be very broad. [0003] Grass cloth is...
