Description

Method for improving bonding fastness of nano ZnO on modified polyester fabric
Technical Field
The invention belongs to the field of nano material functional finishing, and particularly relates to a method for improving the bonding fastness of nano ZnO on a modified polyester fabric.
Background
The nano ZnO has the advantages of good photocatalytic activity, excellent stability and heat resistance, no secondary pollution, no irritation, no toxicity to human bodies, low price and the like, and becomes a green environment-friendly photocatalytic material with the most development prospect at present. The ZnO has a forbidden band width of 3.27eV, can effectively absorb ultraviolet light, has good photocatalytic performance, and can convert pollutants attached to the surface of ZnO into water, carbon dioxide and other small molecular compounds by enabling electrons in ZnO to jump by absorbing energy in the ultraviolet light so as to form electron-hole pairs and enabling the pollutants to undergo redox reaction. Besides optical and photocatalytic properties, the nano ZnO material also has the properties of antifouling, disinfection, bacteriostasis, wetting and the like. The antifouling performance of the composite material mainly depends on the photocatalytic performance of a ZnO material, and the ZnO material can convert oxygen in water and air into active oxygen under certain illumination, so that organic dirt is damaged, and the self-cleaning effect is achieved. Therefore, after ZnO is treated on the polyester fabric, the antifouling efficiency of the fabric can be obviously enhanced; inhibit the growth of microorganisms and greatly prolong the service life of the fabric.
Polyester fibers have excellent physical and chemical properties and are favored in textile industries such as fabrics, bedding, clothes and the like and other industries. However, the surface of the fiber is smooth, and no hydrophilic group exists on a macromolecular chain, so that the polyester fiber is easy to generate static electricity, poor in hydrophilicity and poor in serviceability; and no group in the nano ZnO can be combined with the polyester fabric, so the nano ZnO can only exist on the surface of the fabric in a physical adsorption mode, and the nano ZnO does not have a strong chemical bond on the fabric, is easy to fall off, and causes the fabric to lose various excellent performances. The above problems all limit the popularization of functional textiles in the market, so that the problem of poor durability of ZnO on polyester fabrics is urgently needed to be solved.
Disclosure of Invention
The invention aims to overcome the defect that ZnO cannot be washed on polyester fabric in the prior art and provide a method for improving the bonding fastness of nano ZnO on modified polyester fabric. The preparation process can effectively improve the bonding fastness of ZnO and the modified polyester fabric, broadens the application range of the functional polyester fabric, and has simple process and convenient operation.
The purpose of the invention can be realized by the following technical scheme:
a method for improving the bonding fastness of nano ZnO on modified polyester fabric comprises the following steps:
(1) dissolving low molecular weight chitosan in dilute acetic acid solution;
(2) soaking the polyester fabric subjected to plasma treatment into the solution obtained in the step (1) for reaction, adopting two-soaking and two-rolling to enable chitosan to fully permeate into the fabric, and pre-drying, baking and drying to obtain a modified polyester fabric;
(3) uniformly dispersing zinc oxide in the ultrapure water solution by adopting ultrasonic oscillation;
(4) adding magnesium chloride into the solution obtained in the step (3), and fully stirring;
(5) adding a silane coupling agent into the solution obtained in the step (4), and fully stirring;
(6) and (3) putting the modified polyester fabric into the solution obtained in the step (5), controlling the temperature and carrying out ultrasonic oscillation, padding the fabric in a two-padding and two-rolling manner, and pre-drying, baking and drying to obtain the functional modified polyester fabric for improving the bonding fastness of the nano ZnO.
The concentration of the dilute acetic acid solution in the step (1) is 1-3 wt%.
The plasma treatment time in the step (2) is 3min-10min, the power is 30-80W, the plate spacing is controlled to be 2.5mm-10mm during the plasma treatment, the rolling residual rate of the second soaking and second rolling is 65% -85%, the pre-drying temperature is 60 ℃ -90 ℃, and the baking temperature is 120 ℃ -180 ℃.
The concentration of the zinc oxide in the step (3) is 14g/L-20 g/L.
The concentration of the magnesium oxide in the step (4) is 2g/L-3 g/L.
In the step (5), the silane coupling agent is N-beta- (aminoethyl) -gamma-aminopropylmethyldimethoxysilane, and the concentration of the silane coupling agent in the solution is 1-4 wt%.
In the step (6), the ultrasonic oscillation time is 0.5-2.5h, the ultrasonic oscillation frequency is 40KHz, the temperature is controlled at 30-60 ℃, the rolling residue rate of the second soaking and the second rolling is 65-90%, the pre-flood temperature is 70-90 ℃, and the baking temperature is 120-180 ℃.
When the silane coupling agent is brought into contact with water,hydrolysis and polycondensation reactions with water are easily caused as shown below. When the silane coupling agent is hydrolyzed, alkoxy in the coupling agent can be removed to form silicon hydroxyl; the silicon hydroxyl can react with OH in the solution under neutral or alkaline environment-Reacting to form silicon oxygen anions; and the silicon oxygen anions can attack silicon of another molecule to form a dimer, the silane coupling agent forms a polycondensate by the method, and the silane coupling agent contains a large amount of silicon hydroxyl and amino after polycondensation.
Figure BDA0001633082720000031
When ZnO is added to the system, the silicon oxide anions formed by hydrolysis will partially attack ZnO, thereby grafting the silane coupling agent to ZnO as shown below. ZnO treated by the coupling agent can be firmly combined with the coupling agent in a covalent bond mode.
Figure BDA0001633082720000032
The analysis shows that a large number of hydroxyl groups are formed after the silane coupling agent is hydrolyzed and condensed, and can react with hydroxyl and amino in the modified polyester fabric to form a strong chemical bond, so that the bonding fastness of the nano ZnO and the modified polyester fabric is improved.
Figure BDA0001633082720000033
Therefore, the silane coupling agent can be used as a 'molecular bridge' for connecting the modified polyester fabric and the nano ZnO, so that the bonding fastness of the nano ZnO on the modified polyester fabric is greatly improved, and the washing resistance is improved.
Compared with the prior art, the invention has the following advantages:
1. aiming at the problem of poor durability of the nano zinc oxide and the polyester fabric, the nano zinc oxide, the magnesium chloride, the silane coupling agent KH602 and the modified polyester fabric are treated for 1 hour in ultrasonic oscillation at 40 ℃ by a one-step method, so that the nano zinc oxide is uniformly distributed on the surface of the polyester fabric. The method has the advantages of simple production process, short time consumption, energy conservation, convenient operation and easy popularization and large-scale production.
2. The nano ZnO modified polyester fabric prepared by the invention still has good photocatalysis and uvioresistant performance after being washed, and the physical and mechanical properties of the polyester fabric are not greatly influenced after being treated.
