Description

Wormwood diapers

technical field

The utility model relates to a wormwood diaper, which specifically belongs to the field of sanitary products.

Background technique

Diapers are nursing hygiene products mainly designed for infants and young children. At present, the structure of paper diapers at home and abroad is mostly composed of three parts: surface covering layer, absorbent core layer, and composite bottom film layer. The surface covering layer is close to the body of infants and young children, which promotes the rapid penetration of urine and effectively prevents rewetting, keeping the surface layer of diapers dry. The absorbent core layer can quickly absorb urine, disperse urine and spread it throughout the core layer, and finally absorb and store urine. The composite bottom film layer is the outermost structure of the diaper. Has impermeable performance. It can prevent the moisture in the absorbent core from seeping out.

Diapers are used to absorb urine excreted by the human body, and the urine can be stored in the absorbent layer through the liquid storage function of the diaper structure. If the replacement process is not timely, the urine in the diaper will contact the skin for a long time. Excessive moisture will often cause inflammation such as redness and eczema on the skin, causing damage to the buttocks. These negative effects have a certain impact on the use of diapers. The skin of infants and young children is very thin, and the thickness is only equivalent to one-tenth of that of adults. Especially the anti-friction stratum corneum is very thin, the collagen fibers in the dermis are few, and it is easy to be damaged when being rubbed. In addition, the function of the immune system has not yet been fully developed, and the resistance is weak, and allergies often occur due to the stimulation of moisture in unsuitable diapers.

When using diapers, how to avoid skin allergies of infants and young children due to the stimulation of wet diapers needs to be solved. Therefore, there is a potential market demand for baby diapers that can more effectively play a role in sterilization and anti-inflammation.

Utility model content

The purpose of the utility model is to provide a wormwood diaper.

The wormwood paper diaper has the effects of sterilization and anti-inflammation. It can prevent the skin infection of infants and young children.

The wormwood paper diaper is composed of a surface coating layer, a diversion layer, an absorbent core layer, a wormwood chip, and a composite bottom film layer.

The wormwood paper diapers are sequentially composed of a surface coating layer, a flow guide layer, an absorbent core layer, a wormwood chip, and a composite bottom film layer from the inside to the outside.

The wormwood diaper is formed by bonding the edge parts between the layers by hot melt adhesive.

The surface covering layer is made of non-woven material. The surface wrapping layer has better air permeability, which can make the wormwood diapers fresh and dry.

The non-woven fabric is composed of directional or random fibers and is a new generation of environmentally friendly materials. It has the characteristics of moisture-proof, breathable, flexible, light weight, non-toxic and non-irritating, low price, and recyclable.

The guide layer is made of non-woven material. Its perforated structure can speed up the absorption of liquid in the longitudinal direction and effectively conduct urine.

The punching structure is a funnel punching method. The upper part adopts a large pore size, which reduces the contact surface with the skin, and at the same time absorbs more liquid instantly. The lower part adopts small aperture, which can effectively prevent the liquid from seeping back. The perforated design also has the function of drainage, which can directly drain the liquid permeated from the surface coating layer into the absorbent core layer. And it can ensure that the urine in the diaper is not easy to flow back.

The absorbent core layer is a layered structure composed of dust-free paper, virgin wood pulp and polymer water-absorbing resin. The layer structure of the absorbent core is from top to bottom as the upper part of dust-free paper, virgin wood pulp, polymer water-absorbing resin, and lower part of dust-free paper. Effectively improve the water absorption, softness and breakage of diapers.

The dust-free paper, also called dry-laid paper, has unique physical properties, such as high elasticity, high water absorption and good water retention, and is widely used in sanitary care products.

The source of the primary wood pulp is wood pulp, that is, pulp made from fibers extracted by cooking wood chips. Virgin wood pulp simply means pure pulp that is made directly from wood chips and has not been used.

The polymer water-absorbing resin is a functional polymer material. It can absorb a hundred times, even a thousand times its own weight in water, and has a strong water retention capacity, so it is also called a super absorbent or high water retention agent.

The wormwood chip layer is formed by bonding wet-strength paper and wormwood powder preparation. The layer structure of the wormwood chip is sequentially from top to bottom as an upper wet strength paper, a slow-release medicine powder layer, and a lower wet strength paper. The wormwood chip makes the product have the effects of sterilization, anti-inflammation and anti-allergy.

The wet strength paper refers to the paper added with wet strength agent. When damp or soaked in water, it still maintains more than 15% of its dry strength and can resist cracked or dissociated paper.

The wet strength agent is a papermaking auxiliary that can greatly improve the dry and wet strength of a page. It is non-toxic and odorless, and is suitable for the production of various papers with wet strength requirements.

In the described wormwood powder preparation, the wormwood is made into a wormwood powder preparation by adopting a sustained-release technology. It has inhibitory and killing effects on various viruses and bacteria. Prevents eczema and itchy skin. At the same time, its special fragrance can help sleep and repel mosquitoes.

The sustained release technology adopts physical sustained release. By embedding the wormwood powder in the sustained-release agent, the release of the wormwood powder is hindered. It can prolong the action time of wormwood powder.

The composite bottom film layer is composed of breathable bottom film and non-woven gauze. It plays a good role in preventing urine leakage, comfort and ventilation. The product is guaranteed to be comfortable and dry. The air-permeable base film is a polymer material, which prevents the penetration of water and makes the breathable base film have a waterproof function. The air-permeable bottom film and the edge part of the non-woven gauze are bonded by hot-melt adhesive.

The hot melt adhesive is a kind of plastic adhesive. Within a certain temperature range, its physical state changes with the change of temperature, but its chemical properties remain unchanged. It is non-toxic and tasteless, and is an environmentally friendly chemical product.

The beneficial effect of the utility model is that the skin of infants can be better protected. Enhanced the bactericidal and anti-inflammatory effects of diapers. It can better avoid allergies on the skin of infants and young children due to the stimulation of wet diapers.
