Problems solved by technology

[0004] In order to improve the hydrophilicity of fabrics, CN 01110561.5 (a super-amphiphilic fabric fiber and its preparation method and application) discloses a low-temperature plasma treatment technology, which utilizes the plasma in a certain atmosphere to interact with the fabric surface, and introduces New groups are used to change the hydrophilicity of fabrics, but the hydrophilic effect of plasma atmosphere treatment fabrics cannot be maintained for a long time and the equipment is expensive; CN 200410037803.0 (Use of superhydrophilic and / or superlipophilic nanoporous materials) discloses A kind of fiber or fabric that is breathable and sweat-wicking, which uses nano-porous materials such as nano-silicon oxide and / or titanium oxide to coat the surface of the fiber or fabric, but the preparation of nano-porous materials in this method needs to remove the pore template agent at high temperature and It is necessary to carry out plasma pretreatment to the fabric to increase the polar components of the surface; CN200710002393.X (hydrophilization nano-finishing method for the surface of keratin porous material fabric) discloses that nano-functional materials can be fixed on On various keratin porous fabrics, the hydrophilicity and comfort of the fabric are increased. This method is simple in process, convenient in operation and low in production cost, but the treated fabric has poor hand feeling and poor washability

Abstract

The invention relates to a nano finishing method for preparing a super hydrophilic wool fabric with washing fastness, which is particularly suitable for super hydrophilicity finishing of the high-grade wool fabric. The method of the invention comprises the following steps of: carrying out pretreatment on the wool fabric by using a coupling agent, then regulating a pH value of a reaction solvent, soaking the pretreated wool fabric in the reaction solvent and stirring the mixture at a constant temperature; and adding solution of a precursor containing silicon dioxide (solution of other functional nanoparticles or precursors thereof can be also added) into the reaction solvent in which the wool fabric is soaked, then regulating the pH value of reaction solution, oscillating the reaction solution for a certain time at a constant temperature, taking the wool fabric out, washing the wool fabric and drying the wool fabric. The method of the invention can carry out functionalization treatment on the wool fabric when preparing a nano material so that the wool fabric has effect on adsorption and fast drying and is also very washable. The method of the invention has simple operation, can realize functional design of the fabric from the microcosmic field and can integrate various functions of adsorption and fast drying, bacteriostasis, self cleaning and the like into one body.

Description

technical field [0001] The invention relates to a nano-finishing method for preparing super-hydrophilic wool fabrics with washability, and is especially suitable for super-hydrophilic finishing of high-grade wool fabrics. Background technique [0002] The hydrophilicity of fibers is an important factor to ensure the natural adjustment system of the human body and determine the comfort of clothing. The hydrophilicity of fibers includes two aspects, namely, the hygroscopicity and water absorption of fibers. When the fiber is sweating in the human body, firstly, it absorbs vapor water from the skin, which is manifested as the hygroscopicity of the fiber; secondly, it absorbs the liquid phase moisture from the skin, which is manifested as the hygroscopicity of the fiber. The hygroscopicity and water absorption of the fiber are not only related to the chemical structure of the fiber itself, but also related to the physical structure and morphological structure of the fiber, such...
