Abstract

The invention relates to a method for finishing the durable function of a cellulose fabric, which comprises the following steps: firstly, soaking or padding the cellulose fabric by using an aqueous solution of a cationic modifier namely a finishing liquor A; secondly, soaking or padding the cellulose fabric in a prepared finishing liquor B; thirdly, treating the cellulose fabric in a water-containing medium solution comprising sodium, potassium or lithium sodium silicate and a textile functional finishing agent; and finally, pre-baking the cellulose fabric at a temperature of between 80 and 100 DEG C, washing the cellulose fabric, and baking the cellulose fabric at a temperature of between 120 and 170 DEG C. The method is simple and safe, has low requirements on the performance of equipment, is easy for industrialization and is suitable for the cellulose fabric, and a fabric prepared by the method has lasting functionalities.

Description

technical field [0001] The invention belongs to the field of functional finishing methods for cellulose fabrics, in particular to a durable functional finishing method for cellulose fabrics. Background technique [0002] The application of sol-gel technology based on inorganic or organometallic compounds as precursors (starting materials) to the functional finishing of textiles has begun to emerge. The fabric is padded with the nano-sol of inorganic oxide, and then undergoes a heat treatment process. The nano-sol condenses with each other to form a transparent metal or non-metal oxide xerogel coating on the surface of the fabric. or film. By adding some functional finishing agents to the nano-sol to modify the nano-sol, the functional finishing agent can be evenly covered in the network structure of the three-dimensional metal oxide, thus endowing the fabric with different properties. These functional finishing agents can be anti-ultraviolet finishing agents, antibacterial...
