Abstract

The invention discloses a waterproof oleophobic cloth material and a manufacturing method thereof. The waterproof oleophobic cloth material comprises cloth body and a waterproof oleophobic layer. Themanufacturing method of the waterproof oleophobic cloth material is reasonable. According to the manufacturing method, cloth fibers are soaked in a silicon dioxide mixed solution prepared from nano silicon dioxide and ethylene glycol first and then woven, the cloth body has the performance of a waterproof oleophobic layer, and then a waterproof layer is attached to the outer side of a silicon dioxide mixed solution layer by soaking the cloth body in a mixed solution of polyether-modified silicone oil, tetraethoxysilane, polydimethylsiloxane, a silane coupling agent and a catalyst. The servicecycle is greatly prolonged, and the waterproof oleophobic cloth material causes no irritation to the skin and is applicable to cloth.

Description

technical field [0001] The invention relates to the technical field of waterproof and oleophobic fabrics, in particular to a waterproof and oleophobic fabric and a production method. Background technique [0002] Cloth is a commonly used material in decorative materials. Including chemical fiber carpets, non-woven wall coverings, linen cloth, nylon cloth, colored tape, flannel and other fabrics, fabrics play a very important role in decoration and display, and are often the main force that cannot be ignored in the entire sales space , a large number of fabrics are used for wall decoration, partition, and background treatment, which can also form a good commercial space display style. [0003] At present, the fabrics on the market are poor in waterproof and oleophobic performance. Over time, the waterproof and oleophobic layer will gradually disappear and lose the waterproof and oleophobic function. Therefore, an improved technology is urgently needed to solve the problems e...
