Abstract
The invention discloses a kind of Modification of Cotton Fabric method, comprise the steps: by COTTON FABRIC first through chitosan derivatives modification, and then through Low Temperature Plasma Treating, finally carry out the test of reactive dyeing testing inspection.The present invention is by improving traditional COTTON FABRIC cation modifying technique, adopt the mode that chitosan hydroxyl derivative and Low Temperature Plasma Treating technology combine, modified fiber is strengthened the absorption of the dyestuff of the anionics such as REACTIVE DYES and binding ability, thus improve the dye-uptake of dyestuff, and dyeing uniformity and dyefastness all can meet related request.
Description
Technical field
The invention belongs to textile dyeing and finishing manufacture field, be specifically related to a kind of Modification of Cotton Fabric method.
Background technology
In cotton fabric by utilizing reactive dye dyeing course, dyestuff utilization rate is low, dyestuff runs off large, and REACTIVE DYES is the dyestuff of anionic, and there is certain repulsion between COTTON FABRIC, make dyestuff not easily upper dye, usually will add the neutral electrolyte such as glauber salt, salt to impel the upper dye of dyestuff, if do not add neutral electrolyte, then dye-uptake is low, Color is poor, does not reach desirable colored state.But electrolytical use environmental pollution is serious, and wastewater treatment difficulty is large.
The less salt of current REACTIVE DYES or salt-free dyeing technique by the REACTIVE DYES, the exploitation salt-free dyeing auxiliary that dye under exploitation salt-free conditions and can carry out chemical modification to strengthen the adsorption capacity to dyestuff to fiber.And the cation modifying of COTTON FABRIC is exactly one wherein.The cation modifying technology of COTTON FABRIC, cationizable group can be introduced on cotton fiber, by the introducing of cation group, reduce the Zeta potential on cotton fiber surface, the repulsion between original anionic dyes and fiber can be reduced, greatly improve the dye-uptake of anionic dyes, improve fiber to the absorption of dyestuff and binding ability, reduce the consumption of neutral electrolyte in dyeing course, dyeing can be carried out under less salt or salt-free state, thus minimizing discharge of wastewater, reduce the pollution to environment.
But currently used cation modifying method, there is the cation modifying agent adopted and have harmful effect to environment, or after with cation modifier process, cause uneven dyeing, the problems such as dyefastness is low, carry out modification as adopted epoxies nitrogen-containing compound and can cause certain pollution to environment, the cation modifying agent of picture quaternary ammonium salt then can be high because of reactivity, adsorb too fast and cause the uneven phenomenon that dyes, even if or adopt as this eco-friendly auxiliary agent of shitosan, but it can not be directly water-soluble, and must be dissolved in the acid solutions such as acetic acid and could use, cotton fiber is had a certain impact, though effect is improved but neither be very desirable simultaneously.
Summary of the invention
