Embodiment 1

[0021] A production method of tea polyphenol cellulose fiber spunlace non-woven fabric, comprising the steps of:

[0022] (1) Preparation of tea polyphenol cellulose fibers Pump 50L of water into the glass-lined reactor, start stirring, and add 10Kg of tea polyphenols, after fully dissolving, adjust the pH value of the tea polyphenols aqueous solution to 4-5 with dilute hydrochloric acid , then heat the tea polyphenol aqueous solution to 70-80°C, maintain the system temperature at 70-80°C, and add 3.5L of γ-(2,3-epoxypropoxy)propyl trimethyl dropwise to the system within 20-30min under the condition of stirring Oxysilane, after the dropwise addition, raise the system temperature to 100-110°C, maintain the system temperature at 100-110°C for 9 hours, then use dilute sodium hydroxide solution to adjust the pH value of the reaction solution to 7-8 to obtain tea polyphenols Pretreatment solution, then after cooling down to room temperature, use the injection system to add the prep...

Abstract

The invention discloses tea polyphenol cellulose fiber spunlaced non-woven fabrics and a production method of the same, and relates to the field of preparing functional spunlaced non-woven fabrics. The spunlaced non-woven fabrics is formed by the following fibers of the weight percentages: 10-15% of tea polyphenol, 85-90% of cotton fiber or synthetic fiber, wherein 50-75% of tea polyphenol is grafted on cellulose through a silane coupling agent, and the residual 25-50% of the tea polyphenol drift away and are attached to the cellulose; the denier of the fiber is 1.33-1.67dtex; the production method is combined with the preparation process of the tea polyphenol cellulose fiber; during the spunlacing process, tea polyphenol pre-treatment fluid is also used to process; and during the spunlacing process, the content of tea polyphenol is further added, and eventually the content of the tea polyphenol in the non-woven fabrics can achieve 20-30%.

Description

technical field [0001] The invention relates to the field of functional spunlace nonwoven fabric preparation, in particular to a spunlace nonwoven fabric of tea polyphenol cellulose fiber and a production method thereof. Background technique [0002] A lot of sweat, sebum, and other secretions produced by the human body will adhere to the clothes you wear, and at the same time, the clothes you wear will also be stained by the dirt in the environment, and become an important medium in the process of breeding and transmitting germs . Human skin is a good nutrient base for microorganisms in nature. Under normal circumstances, some resident bacteria on people's skin play a role in protecting the skin from the harm of germs. However, once the flora in the microorganisms is out of balance, a small amount of germs in them will multiply in large numbers and pass through the skin, respiratory tract, digestive tract and The mucous membrane of the reproductive tract is harmful to the...
