Example Embodiment

[0032]Example 1

[0033]The medical protective clothing fabric provided in this embodiment is prepared by the following steps:

[0034](1) The chitosan and sulfuric acid were dissolved in water, and in the three flasks, the constant temperature was maintained after stirring to 50 ° C, and the HI aqueous solution was added to the three flasks at a 5 ml / min, and the drip completion After the constant temperature reaction is 1 hour, then the temperature is lowered to -8 ° C, and the yellow crystal A is obtained, wherein the chitosan, H2SO4Hi, water mass ratio is 1: 0.6: 0.3: 4, with the following reaction equation:

[0035]

[0036]Wherein is 30 to 60.

[0037](2) Crystal A is dissolved in diethyl ether, and the newly cut metal magnesium is cut into small pieces, and the diethyl ether solvent is added to be stirred at room temperature for 3 hours, then the solvent is removed at 30 ° C, and the remaining solution is heated to 60 ° C, The filtration was filtered, then the filtrate was cooled to -5 ° ...

[0044]Example 2

[0045]The medical protective clothing fabric provided in this embodiment is prepared by the following steps:

[0046](1) The chitosan and sulfuric acid were dissolved in water, and the three flasks were added, and after the stirring was heated to 55 ° C, the constant temperature was maintained, and the Hi aqueous solution was dripped with a 5.5 ml / min to three flasks, dripping After completing, the constant temperature reacts for 1.5 hours, then cooling to -9 ° C, and is pale yellow crystal A. Among them, chitosan, H2SO4Hi, water mass ratio is 1: 0.7: 0.35: 4.5.

[0047](2) Crystal A is dissolved in diethyl ether, and the newly cut metal magnesium is cut into small pieces, and the diethyl ether solvent is added, stirred at room temperature for 3.5 hours, then the solvent is removed at 35 ° C, and the remaining solution is heated to 65 ° C, The heat was filtered, then the filtrate was cooled to -6 ° C, and the solid B was obtained. Among them, the mass ratio of crystal A, ...

Abstract

The invention relates to a preparation method of a medical protective clothing fabric, which comprises a process of coating one of two surfaces of base cloth with a film and a process of coating the other surface of the base cloth with a light reflection coating, and the raw material of the light reflection coating comprises a modified chitosan- titanium dioxide composite material containing a modified chitosan surfactant, according to the modified chitosan surfactant, chitosan is used as a base material, 1, 4-dioxane is used as a grafting agent, chitosan is modified, rutile type titanium dioxide is promoted to form a compact nano-film coating by utilizing the film-forming property of chitosan and an ethoxy structure on a modified body, and excellent sunlight reflection capability is formed; and when the modified chitosan- titanium dioxide composite material is used in preparation of protective clothing fabric, a light reflection coating is formed on the base cloth, has the effect of reflecting near infrared radiation of sunlight, reduces the internal temperature of the protective clothing and is firmly bonded with the base cloth, so that the protective clothing does not fall off when being worn, and the wearing comfort of the protective clothing in summer is improved.

Description

technical field [0001] The invention belongs to the technical field of textiles, and relates to a preparation method of a fabric for medical protective clothing. Background technique [0002] With the emergence of SARS and the new crown epidemic, protective clothing with the function of isolating viruses, body fluids, blood, and alcohol has become an important reserve material for countries all over the world. Protective clothing is an important barrier to protect the safety of medical personnel, so the quality of protective clothing is related to everyone. The life safety of medical staff who are in close contact with virus carriers requires very high protection performance. In order to achieve the purpose of isolating viruses, body fluids and blood in medical protective clothing, the existing protective clothing needs to be coated or coated with a film on the fabric. [0003] However, while the protective performance of protective clothing is improved, the air permeabilit...
