Energy-saving and environment-friendly fabric pretreatment agent for printing and dyeing and preparation method of energy-saving and environment-friendly fabric pretreatment agent

Abstract

The invention discloses an energy-saving and environment-friendly fabric pretreatment agent for printing and dyeing. The fabric pretreatment agent is prepared from components in parts by weight as follows: 5-15 parts of an enzyme preparation, 5-10 parts of a penetrant, 5-10 parts of a chelating dispersant, 5-10 parts of a refining agent and 60-90 parts of water. According to the energy-saving andenvironment-friendly fabric pretreatment agent for printing and dyeing and a preparation method of the pretreatment agent, the biological enzyme refining agent and the enzyme preparation are used in apretreatment process, and an alkali agent can be prevented from being used during desizing and refining; as a biological catalyst, the biological enzyme is harmless, non-toxic and low in consumption,treatment conditions are mild, produced wastewater is biodegradable, and pollution is reduced.

Description

technical field [0001] The invention belongs to the technical field of fabric manufacturing, and in particular relates to an energy-saving and environment-friendly fabric pretreatment agent for printing and dyeing and a preparation method thereof. Background technique [0002] As we all know, the surface of cotton fiber contains pectin, wax and other hydrophobic substances. The traditional process mainly uses pretreatment measures such as high temperature and alkali scouring to remove these hydrophobic substances before dyeing. It is carried out in an independent process, the defects of its operation are very obvious, and the process is complicated. The pretreatment process of high temperature and alkali scouring needs to be carried out at 98°C-100°C, which requires a large amount of steam consumption, high energy consumption, long time, low efficiency, and high cost. In addition, the alkali scouring process needs to use Caustic soda leads to the discharge of a large amount...

[0002] As we all know, the surface of cotton fiber contains pectin, wax and other hydrophobic substances. The traditional process mainly uses pretreatment measures such as high temperature and alkali scouring to remove these hydrophobic substances before dyeing. It is carried out in an independent process, the defects of its operation are obvious, and the process is complicated

The pretreatment process of high temperature and alkali scouring needs to be carried out at 98°C-100°C, which requires a large amount of steam consumption, high energy consumption, long time, low efficiency, and high cost. In addition, the alkali scouring process needs to use Caustic soda leads to the discharge of a large amount of alkaline waste liquid, increases the pressure of sewage treatment, pollutes the environment, and is not environmentally friendly. Moreover, some components of the pretreatment agent will pollute the environment during use, and it is not easy to degrade and discharge after use. , has brought a lot of trouble to fabric pretreatment, so we need a new type of energy-saving and environmentally friendly fabric pretreatment agent for printing and dyeing and its preparation method to solve the above problems and meet people's needs
