Water-absorbent material mainly used for diaper or pad and production method thereof

Abstract

The invention provides a water absorbing material mainly used for napkin and diaper and a production method thereof. The water absorbing material mainly comprises the following compositions in portion by mass: 10 to 45 portions of water-absorption modified polyacrylonitrile fiber, and 55 to 90 portions of a bamboo carbon fiber. 1 to 35 portions of chitin antibacterial moisture-conductive acrylic fiber can be mixed into the compositions. The water absorbing material is processed into non-woven fabric by the water-absorption modified polyacrylonitrile fiber and the bamboo carbon fiber through mixing, opening, carding, spreading, needling, shaping and other steps, overcomes the deficiency of single fiber, has comprehensive performance higher than other materials mixed with other fibers and the water-absorption modified polyacrylonitrile fiber, is applicable to napkin and diaper, or other water absorbing living or medical products, and has the advantages of simple and practical process and low cost.

Description

technical field

[0001] The invention relates to a textile material made by mixing water-absorbing modified polyacrylonitrile fiber and bamboo charcoal fiber. It is mainly used in urinary incontinence care products, such as adult diapers, baby diapers, diapers, urine pads and other products. The core absorbent layer can also be used in other occasions that require moisture absorption and repeated washing, such as clothing linings, insoles, etc. Background technique

[0002] The washable water-absorbing modified polyacrylonitrile fiber is made of polyacrylonitrile fiber as raw material, and the surface layer of the fiber is hydrolyzed by alkali. As a result of hydrolysis, the surface layer becomes a cross-linked body of a hydrophilic polymer containing a carboxylic acid group, and has water-absorbing properties. The core of the fiber is a polyacrylonitrile fiber that has not changed, and the surface layer is made of a material similar to powdery water-absorbing resin. When i...
