Embodiment 1

[0036] a) Weigh 2.51g (0.0093mol) FeCl 3 ·6H 2 O and 1.25g (0.0045mol) FeSO 4 ·7H 2 O was dissolved in 600ml of deionized water, and under the protection of nitrogen at room temperature, 24ml of ammonia water with a concentration of 1.5mol / l was added point by point to the above solution to obtain a black precipitate. The precipitate was washed 5 times with deionized water and ethanol by means of magnetic separation, the precipitate was dispersed in ethanol, 10.42g of oleic acid (equivalent to oleic acid of 10 times the precipitation mass) was added, and ultrasonic dispersion was carried out at 80°C for 30 minutes.

[0037] b) Using ethanol to wash away excess oleic acid with the help of magnetic separation, and transfer the modified nano ferroferric oxide particles into 100 ml of ethanol.

[0038] c) Immerse the polyester fabric in an ethanol solution containing nanometer ferroferric oxide particles modified with oleic acid on the surface for 1 min.

[0039] d) The 222nm excimer ...

Abstract

The invention relates to a method for utilizing excimer laser irradiation to prepare magnetic functional textile, which comprises: adopting a coprecipitation method to prepare nanometer ferroferric oxide granules, then, using oleic acid to modify the surface of the nanometer ferroferric oxide granules, then, dipping polyester fabrics in ethanol solution which contains the nanometer ferroferric oxide granules whose surface is modified by the oleic acid, lastly, utilizing excimer laser irradiation 222nm to irradiate two surfaces of the polyester fabrics after dipping, and finally obtaining the magnetic functional textile with comparatively high fastness to washing. The magnetic functional textile which is prepared by the method has good washability, the method of the invention is simple and novel and has simple technique, few equipment, small strength damage to the polyester fabrics, low energy consumption, convenient extension and the like.

Description

Technical field [0001] The invention belongs to the field of functional textile preparation, and particularly relates to a preparation method for preparing magnetic functional textiles by using excimer ultraviolet light sources. Background technique [0002] There are roughly two ways to prepare magnetic textiles (including textile fibers and non-woven fibers): one is to prepare magnetic fibers by direct shaping, and then to make textiles; the other is to prepare by chemical and physical modification of matrix fibers. [0003] 1. Direct forming method of magnetic fiber [0004] Direct magnetic fiber forming can be used to prepare metal or alloy magnetic fibers and various magnetic organic fibers. The blending spinning method is mostly used, and most magnetic organic fibers can be prepared by this method. Generally, magnetic particles with a particle size of less than 1 micron are mixed into the solution or spinning dope of the fiber-forming polymer, and then melt-spinned or wet-s...
