Embodiment

[0020] A corn fiber thermal cotton made of 100% corn fiber.

[0021] A method for preparing corn fiber thermal insulation cotton, which comprises opening and mixing corn fiber short fibers, then carding them into fiber webs according to the carding parameters, and finally winding the finished product; the steps are as follows: opening→mixing→carding → Laying net → Glue spraying → Drying → Shaping → Slitting → Winding finished product; the drying temperature is 110-130°C, and the drying and shaping time is 3-9 minutes to keep the fiber net uniform, fluffy, soft and strong.

[0022] In the present invention, the spray glue emulsion is a polyacrylate copolymer emulsion prepared from the following raw materials: methyl acrylate (or ethyl ester, n-butyl ester, 2-ethyl ethyl ester, isobutyl ester, etc.). There are many comonomers in polyacrylate copolymer emulsion, commonly used monomers are vinyl acetate, styrene, acrylonitrile, dibutyl maleate, vinylidene chloride, chloroprene, bu...

Abstract

The invention relates to insulation cotton made of pure short corn fibers and a production method thereof. The cotton is made of 100% corn fibers. The method comprises the steps of opening, blending, carding, web forming, gel spraying, drying, shape setting, splitting and finished product rolling. The drying and shape setting temperatures range between 110 DEG C and 130 DEG C and the drying and shape setting time is 3-9min. The invention solves the problems of process temperature and drying and shape setting time during web forming of the corn fibers and also solves the problems caused by that the corn fibers are difficult to form webs due to brittleness, hardness and easy breakage.

Description

technical field [0001] The invention relates to a thermal insulation cotton made of pure corn fiber short fiber and a production method thereof. Background technique [0002] my country is a large country with a population of 1.3 billion, and its demand for food and clothing ranks among the top in the world. However, the solid waste discharge behind the huge consumption is also very alarming. According to data, before the "plastic restriction order" was promulgated, in 2007 The annual consumption of China's plastic synthetic materials exceeds 50 million tons, of which 10 million tons of synthetic fibers for textiles are used. It has become a recognized problem for the large-scale disposal of these wastes. Although synthetic materials come from nature and are manufactured by humans, they are ultimately When it is in nature, it is not easy to be absorbed by nature, thus affecting the ecological environment of nature. [0003] In recent years, the American Grain Association, Car...
