Description

Ultrathin dry bamboo fiber sanitary towel

Technical Field

The utility model belongs to the technical field of sanitary towel, concretely relates to ultra-thin dry and comfortable type bamboo fibre sanitary towel.

Background

The sanitary towel is a material with absorption capacity, the main material is cotton, non-woven fabric, paper pulp or high molecular polymer and high molecular polymer composite paper formed by the above material composites, the design of the side edge is mainly used for preventing side leakage, and because the sanitary towel can be in a certain angle with the sanitary towel body during use, the sanitary towel is easier to rub with a groin part, so the sanitary towel using the side edge of the soft material is more favored by women. The back adhesive of the sanitary towel is a waterproof material, and can retain menstrual blood in the sanitary towel for absorbing the menstrual blood flowing out from the vagina when women have menstrual flow.

At present, dry sanitary napkins prepared from spunlace nonwoven fabrics are popular. The spunlace nonwoven fabric has the advantages of air permeability, flexibility, light weight and easy decomposition. Further, the dryness of the sanitary napkin is closely related to the surface material of the sanitary napkin, and the requirement is also put on the absorption core of the sanitary napkin, etc., and the design of the absorption core of the existing sanitary napkin is usually too thick to reduce the comfort level due to the special purpose of the sanitary napkin for absorbing menstrual blood, but the water absorption and water locking performance is not improved significantly because of the simple increase of the thickness or the number of layers of the core.

The current sanitary towel adopts polymer composite paper or dustless paper as the absorption core, and its touch is relatively poor, and consumer experiences not good enough, and the cotton core fine and handy core sanitary towel who uses soft dress as the advantage has then improved the comfort level effectively, has improved consumer and has experienced, and the absorption rate is also comparatively fast, but the absorbed amount is also general, and thickness is great, produces vexed wet sense easily, causes the peculiar smell, breeds the bacterium, is unfavorable for consumer's health.

With the change of modern life concept, more and more women pay attention to the comprehensive quality of comfort, cleanness and performance of the feminine hygiene product, and the sanitary napkin is required to have natural and non-irritating fabric and soft hand feeling, and is expected to keep the surface dry and reduce the breeding of bacteria. The existing sanitary towel can not meet the increasingly high overall requirements of the contemporary women on the sanitary towel.
