Problems solved by technology

[0002] Disposable medical gloves are generally divided into plastic disposable gloves, latex disposable gloves and nitrile disposable gloves according to the material. The use of disposable medical gloves can effectively avoid cross-infection, but the common problem of these disposable medical gloves is that after wearing Easy to form moisture inside the glove
This is because the human skin emits moisture all the time, and the glove has poor water vapor permeability in order to ensure its isolation effect.

Embodiment 1

[0041] (1) Add 2.62g of tris(2-hydroxyethyl)isocyanurate and 4.83g of 3-aminoadipic acid to 50mL of ethanol, and dropwise add 0.35g of 98% concentrated sulfuric acid, heat to 65°C and stir for 3h After the reaction, the ethanol is recovered through distillation, and the distillation residue is the product; through infrared spectrum detection, it is found that there are isocyanurate, ester group, amino group and carboxyl group in the product, ESI-MS: m / z=691.27 [M+1 ] + ;

[0042] (2) Add 5 g of the product obtained in step (1) and 5 g of sodium carboxymethyl cellulose to 30 mL of water, heat to 70 ° C, stir for 30 min, and vacuumize for 3 h to obtain the core spinning stock solution;

[0043] (3) Add 5g of polyvinyl alcohol, 0.25g of diisopropyl xanthate disulfide and 5g of water-soluble porogen (sodium bicarbonate and ethanol at a mass ratio of 1:2) to 30mL of water, and heat to 70°C Stir for 30 minutes, vacuumize and defoam for 3 hours to obtain the cortex spinning stock s...

Embodiment 2

[0046] The difference between embodiment 2 and embodiment 1 is the preparation of step (1) product, and all the other are the same as embodiment 1.

[0047](1) Add 2.62g of tris(2-hydroxyethyl)isocyanurate and 2.94g of maleic anhydride to 50mL of ethanol, and dropwise add 0.35g of 98% concentrated sulfuric acid, heat to 65°C and stir for 3h, esterification After the reaction, add 0.50 g of azobisisoheptanonitrile dropwise, continue heating to 65°C and stir for 5 hours. After the polymerization reaction, ethanol is recovered by distillation, and the distillation residue is the product, and the degree of polymerization is 2000; the product is found by infrared spectrum detection There are isocyanurate, ester and carboxyl groups in

[0048] (2) Add 5 g of the product obtained in step (1) and 5 g of sodium carboxymethyl cellulose to 30 mL of water, heat to 70 ° C, stir for 30 min, and vacuumize for 3 h to obtain the core spinning stock solution;

[0049] (3) Add 5g of polyvinyl a...

Abstract

The invention discloses a super-absorbent fiber material for processing a disposable medical glove inner and a manufacturing method thereof, and relates to the technical field of medical materials. According to the super-absorbent fiber material for processing the disposable medical glove inner and the manufacturing method thereof, a composite fiber material with a skin-core structure is manufactured and obtained by utilizing a core-layer spinning solution and a skin-layer spinning solution, the manufactured fiber material has good water absorption and water locking properties, moisture emitted by a human skin can be instantly absorbed, the fiber material is suitable for being used as a disposable medical glove inner processing material, the prepared glove inner can obviously improve the wearing comfort of a glove, the biodegradability is realized, and the pollution to the environment after the disposable medical glove are discarded is reduced.

Description

Technical field: [0001] The invention relates to the technical field of medical materials, in particular to a superabsorbent fiber material for processing disposable medical glove liners and a manufacturing method thereof. Background technique: [0002] Disposable medical gloves are generally divided into plastic disposable gloves, latex disposable gloves and nitrile disposable gloves according to the material. The use of disposable medical gloves can effectively avoid cross-infection, but the common problem of these disposable medical gloves is that after wearing Moisture can easily form inside the glove. This is because the human skin emits moisture all the time, and the glove has poor water vapor permeability in order to ensure its isolation effect. The moisture gathered inside the glove will affect the wearing comfort of the glove, making people feel that the skin cannot breathe. . [0003] In view of the above technical problems, our company has developed a super abso...
