Embodiment 1

[0044] A method for modifying the surface of wool by catalytic oxidation, using loose wool fibers as wool to be treated, and performing the following steps in sequence:

[0045] 1) Add iron oxide nanoparticles to the 1.0g / L dispersant MF aqueous solution (as a solvent) to prepare an aqueous dispersion of iron oxide nanoparticles; the concentration of iron oxide nanoparticles in the aqueous dispersion is 10g / L.

[0046] According to the ratio of every 1g of wool fiber corresponding to 1ml of iron oxide nanoparticle aqueous dispersion; the above-mentioned iron oxide nanoparticle aqueous dispersion is evenly sprayed on the wool fiber; during the spraying process, the wool fiber is evenly stirred; thereby making the iron oxide nanoparticle Evenly attached to the wool fiber surface. At this time, the amount of liquid carried by the wool fiber is about 100% (that is, the weight of the wool fiber has doubled). Iron oxide nanoparticles are attached to the surface of the wool fiber....

Embodiment 2

[0053] A method for modifying the surface of wool by catalytic oxidation, using wool tops as wool to be treated, and performing the following steps in sequence:

[0054] 1) Add iron oxide nanoparticles to the 1.0g / L dispersant H-423N aqueous solution (as a solvent) to prepare an aqueous dispersion of iron oxide nanoparticles; the concentration of iron oxide nanoparticles in the aqueous dispersion It is 15g / L.

[0055] Pour the aqueous dispersion of iron oxide nanoparticles into the wool ball dyeing machine, soak the wool tops for 30 minutes, and the bath ratio is 1:15; use a dehydrator to remove the excess iron oxide nano particle dispersions, so that the wool tops are more sensitive to iron oxide. The liquid-carrying rate of the nanoparticle aqueous dispersion is 100%, that is, the weight of the wool top is increased by 100%, so that the iron oxide nanoparticles are attached to the surface of the wool top. The wool is then dried at 100°C-120°C.

[0056] 2) Pour 30-50% H...

Abstract

The invention discloses a wool surface catalytic oxidation and modification method and aims to provide a method for enabling a squama structure part on the surface of wool to be damaged by corrosion or totally stripped and enabling the surface of the wool to be in a smooth form. The wool surface catalytic oxidation and modification method comprises the steps: adding iron-oxide nanoparticles in a dispersant solution to obtain an iron-oxide nanoparticle aqueous dispersion; treating a wool product to be treated by the iron-oxide nanoparticle aqueous dispersion, and enabling the iron-oxide nanoparticles to be uniformly adhered to the surface of the wool product to be treated; treating the obtained wool product to be treated by a solution prepared by H2O2, enabling the adhesion part or the periphery of the iron-oxide nanoparticles to generate location catalytic oxidation, corroding a squama structure on the surface of the wool, and enabling the surface of the wool to be modified; carrying out washing and dehydration by using an aqueous surfactant solution, washing by clean water, and drying. With the adoption of the wool surface catalytic oxidation and modification method, most of the squama structure on the surface of the wool is damaged by corrosion, and the method has the advantages of no AOX (Adsorbable organic chloride) emission and residue by adopting a chloride-free treating method.

Description

technical field [0001] The invention relates to a method for modifying the surface of wool by catalytic oxidation, in particular to a method for scale erosion or peeling by utilizing iron oxide nanoparticles to perform positioning catalytic oxidation on the surface of wool fibers. Background technique [0002] Wool textiles are a premium material for making suits, fashion and knitted sweaters. However, due to the scale layer on the wool surface such as figure 1 As shown, it will cause felting of wool textiles, change the size and shape of clothing, and affect the appearance and performance of clothing; moreover, the dense scale layer will block the penetration and diffusion of dyes into the fiber, affecting the printing and dyeing of wool performance, and the scale layer structure makes the luster of wool products not bright and bright enough, and the hand feel is not smooth and soft enough. Therefore, in the wool spinning industry, the chlorination method is often used to...
