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 five times with deionized water and ethanol at intervals by means of magnetic separation, the precipitate was dispersed in ethanol, and 10.42 g of oleic acid (equivalent to oleic acid 10 times the mass of the precipitate) was added, and ultrasonically dispersed at 80°C for 30 minutes.

[0037] b) Washing away excess oleic acid with ethanol by means of magnetic separation, and moving the modified nano-ferric oxide particles into 100 ml of ethanol.

[0038] c) immerse the polyester fabric in the ethanol solution containing the nano ferric oxide particles whose surface is modified with oleic acid for 1 min.

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

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 andnovel 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 preparation of functional textiles, in particular to a method for preparing magnetic functional textiles by using an excimer ultraviolet light source. 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 forming, and then make textiles; the other is to prepare by chemical and physical modification of matrix fibers. [0003] 1. Direct forming method of magnetic fiber [0004] Magnetic fiber direct forming can be applied to the preparation of metal or alloy magnetic fibers and various magnetic organic fibers. The blended spinning method is mostly used, and most magnetic organic fibers can be prepared by this method. Usually, the magnetic material particles with a particle size of less than 1 micron are mixed into the solution of the fiber-forming polymer or the spinning dope, and then melt-s...
