Problems solved by technology

Although there are many studies on the application of nano-materials in anti-wrinkle finishing, most of them use nano-materials as catalysts or synergistic catalysts to carry out anti-wrinkle finishing on fabrics, and use the characteristics of small volume and size of nanoparticles to fill cotton fibers or inside fiber pores. There are almost no related reports, so it is an important direction to improve the anti-wrinkle effect of cotton fabrics by studying a method of nanomaterials to enhance the anti-wrinkle effect of cotton fabrics.

Abstract

The invention relates to a nanometer material reinforced cotton fabric crease-resistant finishing liquid and an application of the crease-resistant finishing liquid. The finishing liquid comprises a nanometer material, a crease-resistant finishing agent, a catalyst, an initiator, a strong protective agent and a solvent-water. The finishing method comprises the steps of dipping a cotton fabric into the crease-resistant finishing liquid for 3-5min; respectively dipping and rolling for two times, wherein the liquid entrainment rate is 80-85%; drying and baking. The nanometer material reinforced cotton fabric crease-resistant finishing liquid is superior to a conventional crease-resistant finishing liquid and has the characteristics that the tensile strength of the fabric can be remarkably improved, the problem that the strength of an existing crease-resistant finishing fabric is reduced can be obviously improved, and the nanometer material reinforced cotton fabric crease-resistant finishing liquid and the application of the crease-resistant finishing liquid have wide application prospects and market prospects.

Description

technical field [0001] The invention belongs to the field of anti-wrinkle finishing liquid and its application, in particular to a nano-material reinforced cotton fabric anti-wrinkle finishing liquid and its application. Background technique [0002] With the development of society and technological progress, people's requirements for the selection of fabrics are becoming more and more stringent. Cotton fabric is favored by people because it is comfortable to wear and has good hygroscopicity, but it is easy to wrinkle and difficult to care for, which brings inconvenience to production and use, and cannot meet people's needs. Therefore, anti-wrinkle finishing of cotton fabric is an indispensable functional finishing to promote social development. The main reason for the wrinkling of cotton fabrics is that the hydroxyl groups on the cellulose molecular chains in the amorphous region of cotton fibers can slip under the action of external force, and form hydrogen bonds in new p...
