Description

Active carbon composite core and disposable nursing hygienic product

Technical Field

The invention relates to the field of sanitary products, in particular to an active carbon composite core and a disposable nursing sanitary product.

Background

The existing adult incontinence pad products generally focus on the characteristics of leakage prevention, convenience, dryness, lightness, thinness, comfort and the like. In recent years, as the demand for quality of life for people has gradually increased, in addition to the above basic performance requirements, the odor removing performance of incontinence pad products has become a focus of attention of customers. Various methods are tried in the industry to try to introduce the urine odor removing function into the incontinence product, and the main implementation modes comprise three modes of fragrance shielding, urine odor adsorption and bacteriostatic substance addition. Wherein, the fragrance shielding mode does not completely solve the embarrassment caused by using the incontinence pad product, but can be counterproductive, and the secrecy of the incontinence people is further exposed; the product with the fungus inhibiting substances cannot be suitable for all people, and may bring potential safety hazards to some sensitive people. Incontinence products with a urine odour adsorption principle are therefore safer for the user.

Activated carbon adsorbents are increasingly used in incontinence products because of their many pores, fast adsorption rate, large specific surface area, and the like. However, in practice, it has been found that activated carbon-based sorbent materials are difficult to use in incontinence products because: the active carbon generally exists in the form of fine powder or granules, the fine powder has poor adsorption effect, and the granules have stronger adsorption effect due to large pores and are more suitable for removing odor. Activated carbon is a brittle material that is easily crushed and risks damaging the skin after being incorporated into an incontinence pad product. When used in incontinence products, not only does the equipment become soiled and the material in contact with it becomes black, but the particles are crushed and the adsorbent properties do not achieve the desired result. In addition, the user can feel hurting the skin, and the use experience is influenced.

It is seen that the above-mentioned prior incontinence pad hygiene products still have the inconvenience and drawbacks of using activated carbon materials, and further improvements are desired. How to create a new active carbon composite core and disposable nursing sanitary article, make it not only can solve the pollution problem of active carbon granule and press against the skin problem, can also effectively realize the product simultaneously and remove the flavor function, promote user satisfaction, become the object that the industry greatly needs the improvement at present.
