Problems solved by technology

Oil-absorbing fabrics and oil-absorbing cables have limited oil-absorbing surface area and weak adsorption capacity, and most of them use chemical fibers. After oil-absorbing materials are incinerated, causing secondary pollution; oil-absorbing sponges are loose and porous and have a large adsorption surface area, but their mechanical properties are poor. Difficult to reuse

Abstract

The invention provides a water-repellent oil-absorbing three-dimensional porous cotton fabric preparation method, which includes alternately stacking terry fabrics and three-foundation cotton fabricsand then connecting the terry fabrics and the three-dimensional cotton fabrics through connecting yarns, or interweaving warp yarns and weft yarns through binding yarns by a three-dimensional loom, soaking the yarns in a water-repellent oil-absorbing finishing agent, and drying to obtain a water-repellent oil-absorbing three-dimensional porous cotton fabric. The water-repellent oil-absorbing three-dimensional porous cotton fabric prepared by the method has a loose porous structure and a large adsorption specific surface area, has better oil spill adsorption and release capability after water-repellent and oil-absorbing finishing, meanwhile, the fabric has good mechanical properties, can be recycled for multiple times, and can adsorb organic liquids about 20 times of the weight of the fabric in less than one minute. Recycled cotton and the fabric thereof can further be used as cotton fabric with a three foundation structure, the fabric has the advantages of low cost, good performance and rich material sources, after use, the fabric can be used for combustion power generation, and has the advantages of high heat, high enthalpy, secondary utilization without ash and the like, and thusthe industry's demands for new oil spill adsorption materials are met.

Description

technical field [0001] The invention belongs to the technical field of oil spill adsorption materials, and in particular relates to a preparation method of a water-repellent and oil-absorbing three-dimensional porous cotton fabric. Background technique [0002] With the increasing demand for oil in all countries in the world, the trade of petroleum products is on the rise, leading to the rapid growth of the oil transportation industry, especially the largest amount of oil transported by ships, accounting for more than 60% of the oil transportation. The development of marine oil transportation has also drawn public attention to oil pollution in the ocean. As a global pollutant, petroleum is entering the ocean in far greater quantities than other pollutants. According to statistics, of the 3.2 billion tons of oil produced globally each year, about 1 / 1000, or 3.2 million tons, enters the marine environment. serious pollution. [0003] The recovery and treatment methods of wa...
