Problems solved by technology

[0010] The primary technical problem to be solved by the present invention is to provide a water-absorbing material mainly used for diapers or pads in view of the above-mentioned current state of the art, which combines the advantages of the two fibers, overcomes the shortcomings of a single fiber, and has high comprehensive performance. It is a material mixed with other fibers and water-absorbing modified polyacrylonitrile fibers, which is very suitable for application in diapers, urine pads or other life or medical products for water absorption

Embodiment Construction

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0036] The amount of water-absorbing modified polyacrylonitrile fiber can be high or low according to the actual water absorption of modified polyacrylonitrile fiber and bamboo charcoal fiber, and the water absorption and weight design requirements of the final material. It is recommended that the amount of water-absorbing modified polyacrylonitrile fiber used is 10-45%. If the water absorption is too low, the water absorption of the material will not be enough, and the absorbent layer of the product will have to be thickened, making users uncomfortable to wear; excessive use of water-absorbing modified polyacrylonitrile fibers will cause the product to dry slowly and make it inconvenient for users to use. Corresponding bamboo charcoal fiber usage is 90-55%, it is advisable to use the bamboo charcoal fiber of special-shaped mesopore section, a...

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...
