Problems solved by technology

However, there are some defects in traditional processing: harsh reaction conditions (such as high temperature, long reaction time) and high cost; the equipment used in traditional processing technology is complicated to operate and cannot be terminated at any time; factors such as traditional machinery or high temperature can seriously damage the performance of the product; The finishing process is not environmentally friendly and consumes water resources seriously; the processing technology is complicated, there are many uncontrollable factors and side reactions, and the product quality is not easy to control, etc.

specific Embodiment approach 1

[0028] Specific implementation mode one, such as figure 1 In the preparation method of the water-repellent textiles shown in the present invention, the textile base material is soaked in the water-repellent finishing solution, taken out and then rolled, and the excess rate is 70% to 120%. Then, under the condition of normal temperature and inert gas, it is irradiated, then dried or baked, and finished to make water-repellent textiles. The water-repellent finishing solution is a solution in which a water-repellent agent and a nonionic surfactant are added to a solvent.

specific Embodiment approach 2

[0029] Specific implementation mode two, such as figure 2 As shown, the textile substrate is coated with a water repellent agent, and the coating thickness is 1-30um. Then, under the condition of normal temperature and inert gas, it is irradiated, then dried or baked, and finished to make water-repellent textiles.

[0030] In Embodiment 1 and Embodiment 2 above, in the process of padding water-repellent finishing liquid or coating water-repellent agent, the range of electron radiation is greater than 0KGy and less than or equal to 300KGy. The water-repellent agent is a monomer or oligomer of reactive silicone, and the viscosity of the oligomer water-repellent agent is less than 5000mPa.s (25°C) or the molecular weight is less than 30000. The water-repellent agent can be used alone or in combination.

[0031] Drying or baking, the drying temperature range is 50-100°C, and the time is 5-60 minutes; the baking temperature range is 100-180°C, and the time is 10-180s.

[0032] ...

Embodiment 1

[0034] Immerse the cotton fabric in the water-repellent finishing solution containing 4% blocked vinyl silicone oil, take it out and roll it, the rolling rate is 80%, after being irradiated by 65KGy electrons, put it in a dryer at 50°C for 30 minutes. After drying, it is soaped, washed with water and then dried.

Abstract

The invention provides a method for preparing a water-repellent textile. An electron radiation technology is adopted, a reactive organic silicon compound is taken as a water repellent, and the textile is subjected to water-repellent treatment. According to the main technical scheme, the method comprises the following steps: padding the textile in a water-repellent or a coating water repellent, radiating, drying or baking, performing after-treatment, thereby obtaining the water-repellent textile. The water-repellent textile prepared by the method disclosed by the invention is excellent in water-repellent performance and can be reacted at normal temperature, the grafting ratio is greatly improved, and the method has the advantages of simple processing technology, simplicity in control and low energy consumption and is worthy of popularization and application.

Description

technical field [0001] The invention relates to the technical field of textile production and processing, in particular to the preparation of durable and good wearable water-repellent textiles by using electron radiation technology and using reactive organosilicon compounds as water-repellent agents. Background technique [0002] With the continuous improvement of people's living standards and the progress of the textile industry, only the traditional textiles that cover the body and keep out the cold can no longer meet people's needs. Various intelligent and functional textiles have won widespread attention and development, and water-repellent textiles have gained popularity favorite. The so-called water-repellent textiles are usually treated with low surface energy finishing agents to change the composition of the fiber surface layer, so that the critical surface tension of the fabric is reduced so that it cannot be wetted by water. The biggest advantage of this method is...
