preparation example Construction

[0042] A preparation method of sepiolite functional non-woven fabric, comprising the following steps:

[0043] S1. The weight part of the support body is made into powder and passed through a 100-150 mesh sieve to prepare a support body solution; the weight part of the nano-silica particles is prepared into a modifier solution, and the two solutions are uniformly mixed; stir and heat up to 30 At ~50°C, keep stirring for 10-40min, then raise the temperature to 55-70°C, add the above-mentioned parts by weight of alum, keep stirring until the solids are completely dissolved, and filter the dissolved solution through a 100-180-mesh filter device;

[0044] S2, soak the fiber non-woven fabric in NaOH solution, take it out, and wash;

[0045] S3. Cool down the solution obtained in S1, add ammonium bicarbonate and the remaining components in the above parts by weight, and stir to obtain a slurry;

[0046] S4. Under ultraviolet light irradiation, coat the slurry obtained in S3 on the fi...

Embodiment 1

[0054] A sepiolite functional nonwoven fabric, in parts by weight, the raw materials for preparing the sepiolite functional nonwoven fabric include: 90 parts of fiber nonwoven fabric, 30 parts of carrier, 1 part of nano silicon dioxide particles part, 1 part of chitosan;

[0055] The carrier includes attapulgite, activated sepiolite fiber, diatomaceous earth and polyester amide compound, and the ratio of parts by weight is: 1:1:1:0.5. The non-woven fabric is made of polyester.

[0056] The preparation method of the activated sepiolite fiber is as follows: according to the solid-liquid ratio of 1:8, the sepiolite fiber is mixed with the inorganic acid solution, the solid-liquid mixture is ultrasonically cleaned, and then irradiated, and the obtained The activated sepiolite fibers were rinsed and then dried.

[0057] Described polyester amide compound comprises 5mol% tertiary hydrogen carboxylic acid units, and the remainder is aliphatic carboxylic acid units and aliphatic alc...

Abstract

The invention belongs to the technical field of non-woven fabric, and particularly relates to sepiolite functional non-woven fabric and a preparation method and application thereof. The sepiolite functional non-woven fabric is prepared from the following raw materials in parts by weight: 90-110 parts of fiber non-woven fabric, 30-50 parts of a carrier, 1-6 parts of nano-silica particles and 1-6 parts of chitosan; the carrier comprises attapulgite, activated sepiolite fiber, diatomite and a polyester amide compound, and the weight part ratio of the attapulgite, the activated sepiolite fibers, the diatomite to the polyester amide compound is 1: (1-3): (1-2): (0.5-2). By regulating and controlling the proportion of the carrier and other components, the defect that an existing non-woven fabricslurry coating is poor in air permeability or low in oxygen permeability on the basis that non-woven fabric has antibacterial, deodorizing and moisture absorption properties is effectively overcome,the functional non-woven fabric which is high in air permeability and oxygen permeability is prepared, high quality of the functional non-woven fabric is achieved, and the functional non-woven fabriccan be applied to medical cloth, surgical drapes, nursing pads, gypsum linings, outer fixed support linings and splint linings effectively, and the functional non-woven fabric is also suitable for being used in operation sterile towels, bed sheets, diapers and sanitary towels.

Description

technical field [0001] The invention belongs to the technical field of non-woven fabrics, in particular to a sepiolite functional non-woven fabric and a preparation method and application thereof. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of directional or random fibers. They are a new generation of environmentally friendly materials. Low cost, recyclable and so on. [0003] Non-woven fabrics have superior effects in improving the hygienic environment and facilitating use. When non-woven fabrics are used, they are a breeding ground for bacteria. These bacteria use human excrement such as urea in sweat as a source of nutrition, continuously multiply, and emit ammonia with a strong odor. The use of ordinary non-woven fabrics cannot effectively prevent bacterial reproduction and cross-infection. [0004] Existing non-woven fabrics have antibacterial, deodorant, and moisture-absorbing properties, but non-woven fabrics with ...
