A highly absorbent chenille doormat and its production process

Abstract

The present invention discloses a highly absorbent chenille doormat and its production process. Chenille yarn, polyester monofilament and modified fiber are woven into yarn, and then woven into a chenille base fabric through a tufting loom. The chenille base fabric is soaked in an aqueous solution of zinc sulfate hexahydrate, taken out and dried, and then dyed, finished, repaired, and double-bottomed. The macromolecular carbon chain skeleton of the modified fiber contains a large number of hydrophilic groups and has a three-dimensional network structure capable of quickly absorbing a large amount of water. The side chain contains zwitterions, which can achieve the effect of hydrophilic and oleophobic, increasing the stain resistance of the chenille doormat, and further increasing the water absorption effect of the chenille doormat. At the same time, the modified filler contains titanium dioxide. During the drying process of the chenille doormat, titanium dioxide can carry out photocatalysis to achieve a bactericidal effect. When the chenille base fabric is soaked in the zinc sulfate hexahydrate solution, the imidazole groups on the modified fiber can complex with zinc ions to form a zinc organic framework, which can further enhance the photocatalytic effect.

The modified filler uses graphene oxide as a raw material and under the action of dicyclohexylcarbodiimide, the carboxyl group on graphene oxide and the amino group on γ-aminopropyltriethoxysilane undergo a dehydration reaction to obtain pretreated graphene. The pretreated graphene, methyltriethoxysilane, dimethyldiethoxysilane and tetrabutyl titanate are hydrolyzed and polymerized to form a titanium-containing organosilicon structure on the surface of the pretreated graphene, and then calcined under nitrogen protection to obtain a modified filler.
