[0014] Example 1:

[0015] A method for dyeing bamboo fiber fabric with natural dyes, including the following steps:

[0016] (1) Pre-treatment: Soak the bamboo fiber fabric with 0.05% JFC-1 solution for 45 minutes, and wash with water after soaking;

[0017] (2) Drying: Dry the washed bamboo fiber fabric at a temperature of 60°C and dry to 70% dry;

[0018] (3) Dyeing and washing: put the dried bamboo fiber fabric into water at 20℃, bath ratio is 1:20, adjust pH to 4, heat up to 40℃, add natural turmeric dye, keep warm for 20min and heat up to 70℃ for 20min After cooling down to room temperature, take it out and wash; among them, natural turmeric dye is a solution with a mass concentration of 80g / L from mashed turmeric and water, and a sodium hydroxide solution with a mass ratio of 5% and a mass concentration of 10g / L is added. It is made by extraction at ℃ for 70min; the concentration for pH adjustment uses glacial acetic acid with a mass concentration of 1-2g / L.

Abstract

The invention discloses a natural dye dyeing method of a bamboo fiber fabric. The method comprises a step of dyeing a pretreated bamboo fiber fabric by adopting a self-extracted natural turmeric dye under an appropriate condition, and a step of carrying out a reasonable color fixation, water washing and air drying technology. The method which adopts the natural dye to dye the bamboo fiber fabric has the advantages of no pollution to the environment, harmlessness to the human body, complementation with the natural, simple and elegant color style of the bamboo fiber fabric, increase of the ecology and environmental protection properties of the bamboo fiber fabric, substantial increase of the added values of bamboo fiber fabric products, satisfying of the demands of healthy clothing by people, and very strong practical values.

Description

technical field [0001] The invention relates to a fabric dyeing process, in particular to a natural dye dyeing method for bamboo fiber fabrics. Background technique [0002] Bamboo fiber is a kind of cellulose fiber extracted from naturally growing bamboo. It has good air permeability, instant water absorption, strong wear resistance, and has natural antibacterial, antibacterial, anti-mite, deodorant and anti-ultraviolet functions. , experts pointed out that bamboo fiber is a real natural environment-friendly green fiber, and bamboo fiber fabric completely replicates the inherent characteristics of bamboo fiber, which is favored by consumers, but it is also because of its natural green color. It is famous for its environmental protection. At present, most of the chemical dyes used in dyeing not only bring printing and dyeing wastewater, but some chemical dyes also pose a potential threat to human health. They cannot complement the natural and simple style of bamboo fiber fab...
