Embodiment 1

[0022] A process for sand-washing and dyeing environmentally friendly polyester fabrics, comprising the following steps:

[0023] A. Pour soda ash and softener into the industrial washing machine, then add water to make the concentration of soda ash 10g / L and softener 0.3g / L, then put the polyester fabric into the industrial washing machine with a liquor ratio of 1 : 45, stirred 12min at room temperature;

[0024] B. Add vegetable dyes and pH buffering agents into the industrial washing machine, stir evenly at room temperature and adjust the pH value of the system to 7-8, then add 1.5% mordant and sandstone, heat up to 65°C and continue stirring for 25 minutes;

[0025] C. After taking out the fabric, soak it in an acidic solution with a pH value of 5.5-6.2 for 12 minutes;

[0026] D. Dry and iron according to conventional methods to form finished products.

[0027] The softening agent in the step A is a terpolymerized modified silicone oil.

[0028] The plant dyes in the s...

Abstract

The invention discloses an environment-friendly polyester fabric sand washing dyeing process. A one bath process is selected to dye polyester fiber, dyeing and sand washing are completed by one time, at the same time anhydrous sodium sulphate and other inorganic salts are unnecessary, thus reaching environmental protection and energy saving effects; marble sandstones are selected for sand washing, firstly, the polyester surface can be ground to enhance the dyeing effect, secondly the fabric seems to have a natural and friendly dyeing effect, and thirdly only through simple pickling of the fabric in follow-up treatment, the harm of tiny granules to the human body can be eliminated. And by using plant dyes, the process is environment-friendly and healthy. The environment-friendly polyester fabric sand washing dyeing process provided by the invention is a healthy, environment-friendly and energy-saving novel dyeing process.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to an environmentally friendly polyester fabric sand washing and dyeing process. Background technique [0002] With the increasing awareness of human environmental protection and the increasing concern for their own health, the harm of some synthetic dyes to human health and the ecological environment has become more and more noticeable. Existing research results have shown that there are 23 kinds of carcinogenic aromatic amines, more than 100 synthetic dyes may produce carcinogens, and more than 20 synthetic dyes are allergic to the skin. As a result, synthetic dyes and the textiles they dye have made consumers suspicious. Not only that, with the continuous consumption of petroleum resources on the earth, the problem of raw materials for synthetic dyes has become increasingly tense. [0003] Natural dyes are extracted from plant roots, leaves, bark, trunks, hu...
