Problems solved by technology

[0005] The above-mentioned invention mainly adopts the mixed slurry to prepare and produce a kind of special paper for diaper core body wrapping. The produced special paper for diaper core body wrapping is low in strength, and the beating degree and quantitative of the slurry are small. Evenness and strength cannot be guaranteed, and it also increases the difficulty of production and copying. In addition, it cannot effectively absorb and remove odors and harmful gases in diapers

Abstract

The invention discloses a special paper for diapers and a production process thereof, wherein the special paper for diapers adopts virgin coniferous wood pulp, and the basis weight of the special paper for diapers is 50g / m 2 , wherein the beating degree is 28~38°SR; the transverse tensile index of the finished paper is ≥50N•m / g, the longitudinal tensile index is ≥100N•m / g, the longitudinal wet tensile strength is ≥150N / m, and the tear index is ≥8mN• m 2 / g, burst index ≥ 5kPa•m 2 / g, folding resistance ≥ 1000 times. The performance index of the special paper for diapers of the present invention is similar to that of non-woven fabrics used by current diaper manufacturers, and can replace the surface covering layer of diapers; in addition, the special paper for diapers can absorb and remove odors and harmful gases in diapers, making diapers safer and more hygienic , comfortable.

Description

technical field [0001] The invention belongs to the technical field of paper processing, and in particular relates to special paper for diapers and a production process thereof. Background technique [0002] Diapers are a kind of sanitary products commonly used by babies. Generally speaking, diapers are composed of three main parts: surface cover layer, absorbent core layer and base fabric. Surface coatings may also be referred to as coatings. The absorbent core may also be referred to as an absorbent core, or absorbent body. The cover fits snugly against the baby's body, which promotes quick penetration of urine and effectively prevents rewet, keeping the surface of the diaper dry. At present, the covering layer of diapers in the domestic market is basically a non-woven surface layer. The breathable non-woven fabric can improve the air permeability inside the diaper, and the water vapor can flow out of the diaper, and the moisture and heat can be discharged in time, effe...
