Problems solved by technology

However, nearly half of the raw materials used in the non-woven fabrics obtained in this application are seaweed fibers, and the water absorption performance of seaweed fibers is not very strong. Therefore, the non-woven fabrics obtained in this application still cannot meet the requirements for use in terms of water absorption properties. And there are still some deficiencies in mechanical properties

Embodiment 1

[0036] Functional fibers are prepared by the following methods:

[0037] (1) Complete the reaction in a reflux device with magnetic stirring, weigh 1.18g of oxalylhydrazide and add it to a three-necked flask, then add 1mL of absolute ethanol and 2-3 drops of acetic acid, and then drop it in through a constant pressure dropping funnel 1.01 g of 3-penten-2-one was refluxed until a large amount of white solids were precipitated, the reaction was stopped, cooling and suction filtration, the crude product was dissolved in absolute ethanol, and the functional monomer was obtained by low-temperature recrystallization;

[0038] (2) According to the solid-to-liquid ratio of 1g: 10mL, add carboxymethylcellulose sodium into pure water and heat to dissolve, then add acrylic acid, glycidyl methacrylate, functional monomer and N,N-methylenebisacrylamide Dissolve in pure water to form a mixed solution. After stirring for 7-8 minutes, add the obtained mixed solution to the sodium carboxymethy...

Abstract

The invention discloses a fast water-absorbing non-woven fabric, which is made of functional fibers and polyester / nylon composite fibers through hot air or hot rolling process, wherein the mass ratio of functional fibers and polyester / nylon composite fibers is 5:4; the present invention The processing technology of the non-woven fabric is also disclosed. After mixing the functional fibers and the polyester-nylon composite fibers according to the mass ratio, they are opened, carded, cross-laid, bonded by hot air or hot rolling to the fiber webs, and dried. In the present invention, through the synthesis of functional monomers, the copolymerization of functional monomers and acrylic monomers, and the further improvement of chitosan on the spinning solution, functional fibers with high strength, excellent water absorption performance and antibacterial performance are obtained; The fiber not only has high strength, but also has skin-friendly and strong water absorption; the non-woven fabric obtained by thermal spinning of the two kinds of fibers has high water absorption and mechanical properties, and on the basis of meeting the requirements of high water absorption, it also has Good skin-friendly and antibacterial properties, with a wide range of applications.

Description

technical field [0001] The invention belongs to the field of functional fabrics, and in particular relates to a fast water-absorbing non-woven fabric and a processing technology thereof. Background technique [0002] Non-woven fabric is a kind of non-woven fabric, which directly uses polymer chips, short fibers or filaments to form fibers through airflow or machinery, and then undergoes hydroentanglement, needle punching, or hot rolling reinforcement, and finally finishes finishing Formed non-woven fabric. A new type of fiber product with soft, breathable and planar structure, which has the advantages of not generating lint, strong, durable, silky soft, and has a cotton feeling. Non-woven fabrics are widely used in the medical field. During medical operations, patients' blood, body fluids and other liquids are likely to be sprayed on the surgeon. If the protective measures are insufficient, it is easy to cause infection. Moreover, the existing non-woven fabrics have poor w...
