Problems solved by technology

However, it still has the characteristics of complex production process, difficulty in realizing the national standard that the sanitary napkin's water absorption rate must be greater than 7 times, and single function. Therefore, it faces a narrow market and user groups, and is subject to certain restrictions in popularization and application.

Abstract

The invention relates to a biodegradable disposable nursing product and a production method thereof. The biodegradable disposable nursing product comprises a surface layer, a core layer and a bottom layer. Nonwoven fabric made of polylactic acid fibers or nonwoven fabric formed by mixing the polylactic acid fibers with wood pulp fibers is selected as the surface layer. The core layer comprises a first absorption layer and a second absorption layer which are sequentially arranged from top to bottom. The nonwoven fabric formed by mixing the polylactic acid fibers with the wood pulp fibers is selected as the first absorption layer and the second absorption layer. Macromolecular water-absorbing particles are infiltrated in the first absorption layer and the second absorption layer evenly. The nonwoven fabric made of the polylactic acid fibers is selected as the bottom layer. The polylactic acid fibers can guarantee surface dryness and less proneness to sensitization, have good bacteria inhibition and peculiar smell removal functions and also have high biodegradability, so that environmental burdens are not caused and people can live easily and freely in a beautiful green environment.

Description

technical field [0001] The invention relates to a nursing article, in particular to a biodegradable disposable nursing article and a preparation method thereof. Background technique [0002] Statistics show that a woman needs 60 menstrual periods a year and needs about 480 sanitary napkins a year. Calculated based on a piece of sanitary napkin weighing 10 grams, 2 billion women will produce about 9.6 million tons of sanitary napkins a year. Garbage; in addition, with the continuous development of the economy and the continuous innovation of product quality, the amount of children's diapers in my country is increasing day by day; moreover, with the arrival of the aging population, the number of incontinent patients such as long-term bedridden patients and severe patients is also increasing. Supplies are also getting a lot of attention. Due to the relatively large volume of these "white garbage", landfilling according to the current treatment method needs to consume a large amo...
