Embodiment 1
[0036] (1) Straw cellulose extraction and preparation: wash the straw, dry and pulverize it, soak it in an 80°C acid bath for 2 hours and keep stirring, then wash it and put it in an 80°C alkali bath for cooking and keep stirring for 2 hours , washed with water, and collected by suction filtration, soaked in a 50°C water bath with pectinase pH=4.6 for 6 hours, washed, bleached with hydrogen peroxide, washed, filtered and dried to obtain the product straw cellulose;
[0037] (2) Weigh 1g of straw cellulose into a beaker, then inject 5-8mL of 18% sodium hydroxide solution, and stir with a magnetic stirrer. Then put the test tube into a water bath at 25°C~30°C, and keep the temperature constant for about 10 minutes;
[0038] (3) Add 1mlCS to the test tube 2 , and seal the mouth of the test tube with a rubber film to prevent the reactant from overflowing. Stir for 1 hour, during the stirring process, it can be seen that the alkalized cellulose gradually turns orange-red and beco...

Abstract
The invention relates to a preparation method of a highly absorbent man-made fiber membrane, which belongs to the technical field of food processing. It uses grain straw as raw material, and after cleaning, dry and pulverize it, acid bath alkali bath, water washing fiber, suction filtration collection, enzyme treatment in water bath, bleaching suction filtration, drying extraction to prepare straw cellulose, and then cellulose alkali Stir, then add carbon disulfide and stir to make it into an orange-red fluid substance, modify its matrix to make it lipophilic, then add sodium hydroxide to make it a completely uniform orange-red viscose, in sulfuric acid The viscose is drawn with a syringe, and after cleaning, it is air-laid to make a high-adsorption man-made fiber film product. The invention uses straw, sulfuric acid, sodium hydroxide, carbon disulfide and hydrophobic groups as raw materials, and the takeaway oil-absorbing lunch box film prepared by the above-mentioned process has strong oil absorption, can effectively improve the experience of diners, and has a positive effect on protecting the environment. positive effects.
Description
technical field [0001] The invention relates to a preparation method of a highly absorbent man-made fiber membrane, which belongs to the technical field of food processing. Background technique [0002] Taking advantage of the rise of the "Internet +" industry, the food delivery industry has brought a lot of convenience to food orderers, but the problems behind the food delivery companies should not be underestimated. Among them, a large number of takeaway lunch boxes have brought a lot of harm to the environment. Common plastic lunch boxes (mostly made of polypropylene) and aluminum foil lunch boxes are difficult to degrade, while new paper lunch boxes (coated paper bowls) also have the disadvantages of high price and poor practicability. As a result, there is a huge demand for takeaway lunch boxes of emerging materials. [0003] Straw is the biomass waste left over from agricultural production, which is often burned directly to pollute the atmosphere. At the same time, ...
