Embodiment 1

[0031] Embodiment 1: According to the ratio of the amount of substances, it is the ratio of sodium methyl silicate / carbon dioxide=1: 6-50, and carbon dioxide gas is passed into the sodium methyl silicate aqueous solution whose mass fraction is 0.1%-5%, to prepare Colloidal solution of methyl silicate. According to the mass ratio of filter paper / methyl silicic acid colloid solution = 1 / 2-50, soak the filter paper in the methyl silicic acid colloid solution, take it out after 5-10 minutes, wash it with water, and put it in a temperature of 120-180 ℃ Heat treatment in an oven for 5-30 minutes to obtain filter paper with superhydrophobic properties.

Embodiment 2

[0032] Embodiment 2: Potassium methyl silicate is used to replace sodium methyl silicate, and the method of Example 1 is used to obtain filter paper with superhydrophobic properties.

Embodiment 3

[0033] Example 3: Replace the filter paper with kraft paper, facial tissue, cotton or pure cotton knitwear respectively, and use the method of Example 1 to process to obtain superhydrophobic facial tissue, cotton or pure cotton knitwear.

Abstract

The invention relates to super hydrophobic cotton or paper fiber material manufacturing method and their use. It is processed surface modification for the cellulose by silicon material which can be methane sodium silicate, methane potassium silicate, or chlorosilane. Thus the processed cellulose has good super hydrophobic property and air permeability, can be used in garment material, package, health aids fields etc.

Description

technical field [0001] The invention relates to a preparation method of a cellulose material with super-hydrophobic performance, and relates to a preparation method and application of a super-hydrophobic cotton fiber material or a super-hydrophobic paper fiber material. technical background [0002] Cellulose is the most abundant natural polymer in nature, which can be regenerated rapidly, and the annual regeneration capacity exceeds 1.0×10 10 t. Moreover, cellulose also has the advantages of easy degradation, no pollution, and easy modification. Today, cellulose and its derivatives have been widely used in the fields of plastics, textiles, papermaking, food, daily chemicals, medicine, construction and biology, and may become the main raw materials of world chemistry and chemical industry in the future. The development of cellulose materials will be of great significance to improving the ecological environment, changing the human diet structure, increasing energy, and devel...
