Embodiment 1

[0029] Embodiment 1: A kind of preparation method of konjac glucomannan fiber wet tissue

[0030] A preparation method of konjac glucomannan fiber wet tissue, comprising the following steps:

[0031] (1) Preparation of konjac glucomannan acrylate: Take hot water and keep it at 45-50°C, add konjac glucomannan, acrylic acid and concentrated sulfuric acid with a volume concentration of 98% while stirring, and the reaction time is 4 hours; then, Rotate at a speed of 500r / min and evaporate and concentrate the reaction solution until the water content is 0.5%. Add ethanol with a volume concentration of 60% for precipitation. The precipitate is washed 3 times with ethanol with a volume concentration of 95%, filtered and The precipitate was air-dried at room temperature and crushed to obtain substance A, which was set aside; the mass ratio of acrylic acid and konjac glucomannan to water was 1:150, and the mass ratio of acrylic acid to konjac glucomannan was 3.5:1. Concentrated sulfur...

Abstract

The invention relates to a konjac glucomannan fiber wet tissue and a method for preparing the konjac glucomannan fiber wet tissue. The method for preparing the konjac glucomannan fiber wet tissue comprises the preparation of konjac glucomannan acrylic ester, acrylic ester esterification modification, the preparation of konjac glucomannan spinning solution and the preparation of the konjac glucomannan fiber wet tissue. The konjac glucomannan fiber wet tissue is made of natural fibers like konjac glucomannan and corn starch and other plasticizers, wherein the natural fibers are used as main raw materials of the konjac glucomannan fiber wet tissue. The konjac glucomannan is a natural plant polysaccharide, has good water binding capacity, hydroscopicity and antibacterial property and is large in tension strength, good in toughness, and high in tensile strength and bursting strength. Compared with a traditional synthetic fiber wet tissue, the konjac glucomannan fiber wet tissue is made of 100% natural plant fibers, has the advantages of being high in tensile strength, large in liquid absorbing amount, high in liquid maintaining amount, exquisite and soft in hand feeling, sterile, sanitary, low in production cost and free of environmental pollution and doing no harm to human bodies, and accords with modern consumption concepts and market requirements.

Description

technical field [0001] The invention relates to a fiber wet tissue and a preparation method thereof, in particular to a konjac glucomannan fiber wet tissue and a preparation method thereof. Background technique [0002] In our daily life environment, bacteria are everywhere, but due to various social activities such as work and study, hands need to be in constant contact with various foods, so we will be infected with a large number of microorganisms and pathogenic bacteria. So we must develop the habit of washing our hands frequently. However, people cannot wash their hands in time in daily life, especially when performing outdoor activities, which endangers people's health to a certain extent, so the demand for wet paper towels is increasing day by day. Especially in the past two years, the production and market of wet wipes have developed very rapidly, and their uses have become increasingly diversified, and they have gradually become the new darling of the toilet paper ...
