Description

A kind of post-processing method of textile material

technical field

The invention belongs to the technical field of post-processing of textile materials, and relates to a post-processing method of textile materials.

Background technique

In order to improve and improve the quality of textiles and meet the market's requirements for comfort, functionality, fashion, safety and environmental protection of textile products, post-processing of textiles is required. However, wet chemical treatment is currently used for post-treatment. This method has the disadvantages of expensive equipment, complicated process, difficult operation process, difficulty in large-scale preparation, possible pollution caused by the use of chemical substances, and a large amount of resources required to achieve the reaction conditions. In line with the sustainable development advocated by today's society.

For example, wool knitted garments often experience pilling during daily wear and use, which not only seriously affects the appearance and feel of the garment, but also reduces the service life of the garment. At present, the methods of improving the anti-pilling performance of wool fabrics include chemical methods. Typical chemical treatment methods mainly include resin finishing method and chlorination method. These methods can form a film on the surface of the fabric, thereby reducing the friction between fibers. Remove the hydrophobic lipid layer or destroy the disulfide bond in wool keratin, so as to improve the pilling resistance of wool fabrics. However, these wet treatment methods are very unfavorable to the ecological environment due to the use of a large amount of water, energy and chemicals, as well as the production of polluting liquid effluents or toxic waste gas, and are contrary to the path of green and sustainable ecological development.

Therefore, it is necessary to further explore efficient and feasible post-processing technologies for textile materials.

Nanostructured active water ion is a two-phase material structure in which nano-scale water droplets are wrapped with a large number of active oxygen components (including hydroxyl radicals, superoxide radicals, etc.) and electrons. It has been successfully used in air purification, food preservation, Beauty and skin care and other fields. Nanostructured active water ion is a new type of environmental protection technology, based on the theory of electrostatic atomization, by applying high voltage to the liquid water supplied by the metal capillary, it forms a Taylor cone under the action of electrical shear stress and forms a charged jet from the apex The droplets continue to disperse under the interaction of Coulomb repulsion and surface tension, thereby forming nanostructured active water ions. Nanostructured active water ions contain a large number of active free radicals and have strong oxidative properties, which are expected to be used in the post-treatment of textiles.

At present, the existing nanostructure active water ion generating devices on the market have the following problems:

(1) Most of the nanostructure active water ion generators supply liquid in the form of semiconductor condensation, which is prone to unstable liquid supply due to excessive or low external humidity;

(2) The existing nanostructure active water ion generating devices are all single-needle devices, with limited generation and low action efficiency;

(3) The electrodes of the existing nanostructure active water ion generating device are distributed in a ring shape, and the electric field intensity thereof is relatively low;

(4) The parameters of the existing nanostructure active water ion generating devices are all fixed values and single setting, and it is impossible to generate nanostructure active water ions of different sizes by changing the parameters of the generating device to meet the requirements of practical applications.

Therefore, a nanostructured water ion generating device with stable liquid supply, high electric field strength, capable of generating nanostructured active water ions of different particle sizes and high action efficiency was studied, and applied to the post-treatment of textile materials. very important meaning.

SUMMARY OF THE INVENTION

The purpose of the present invention is to solve the problems of expensive equipment, complicated process, difficult operation process, difficult preparation in large area, possible pollution caused by the use of chemical substances, consuming a lot of resources in order to achieve the reaction conditions, The sustainable development and other issues advocated by today's society provide a post-processing method for textile materials, especially to solve the method of improving the anti-pilling performance of wool fabrics in the prior art, which affects the feel of wool fabrics and is very unfavorable to the ecological environment.

Nanostructured active water ion (also called nanometer water ion in business) is a two-phase material structure in which nano-scale water droplets wrap a large number of active oxygen components (including hydroxyl radicals, superoxide radicals, etc.) and electrons. It is applied to the fields of air purification, food preservation, beauty and skin care, etc. There is no report of applying it to the post-treatment of textiles. The present invention attempts to apply the nano-structured active water ions to the post-finishing of fabrics. It is applied to the hydrophilic finishing of polyester fabrics, and can also be used for anti-pilling finishing of wool fabrics, and it may also be used for post-treatment of other fabrics to improve the performance of other fabrics.

As a preferred solution:

In the above-mentioned post-processing method of textile material, the textile material is wool fabric, and the performance is anti-pilling performance. The free radicals in the nanostructured active water ions can decompose the epidermis structure of the wool fiber, making the surface of the fiber smoother and more supple. At the same time, the nanoscale water particles in the nanostructured active water ions are attached to the surface of the fiber, which will also reduce the friction on the surface of the fiber. Therefore, the fiber movement in the fabric is more flexible, and the phenomenon of entanglement is not easy to occur, thereby slowing down the pilling process of the fabric and improving its anti-pilling performance.
