Problems solved by technology

Among them, an important component of diapers, diapers (pads, paper), and urine-separating pads is the water-absorbing core. The existing water-absorbing core has insufficient tensile strength, and it is easy to break, shift, and agglomerate during use. Therefore, a design A kind of hygienic water-absorbent core body and its preparation method are very necessary

Abstract

The invention discloses a sanitary water-absorbing core and a preparation method thereof. The sanitary water absorption core comprises a top layer 1, a middle layer 2 and a bottom layer 3, the middlelayer 2 is arranged at the bottom of the top layer 1, the bottom layer 4 is arranged at the bottom of the middle layer 2, the top layer 1 and the bottom layer 3 are breathable wet strength paper, andthe middle layer 2 is a polymer water absorption resin and low-melting-point composite short fiber mixed layer. The preparation method comprises the following steps of step 1, preparing raw materials;step 2, bottoming the top layer; step 3, forming a middle layer; step 4, covering a bottom layer; step 5, composite molding; and step 6, detecting and storing. According to the sanitary water-absorbing core and the preparation method thereof, the SAP and low-melting-point composite short fiber mixed layer is arranged between the top layer and the bottom layer, so that the diffusion capacity of blood and urine moisture is improved, the tensile force is enhanced, the breakage is prevented, low-melting-point composite short fiber can quickly diffuse the blood and the urine moisture, the diffusedlow-melting-point composite short fiber is quickly absorbed by SAP, the utilization rate is high, the tensile force is enhanced more remarkably, and SAP layers with different gram weights can be arranged on the middle layer to meet the requirement for absorbing moisture.

Description

technical field [0001] The invention relates to the technical field of sanitary products, in particular to a hygienic water-absorbing core and a preparation method thereof. Background technique [0002] Hygiene products include daily chemical products (hand sanitizer, laundry detergent); women's menstrual hygiene products (sanitary napkins, sanitary pads, sanitary tampons); diapers and other excrement hygiene products [diapers, diapers (pads, paper), urine pads ]; skin and mucous membrane hygiene products (wet wipes, sanitary wipes); contact lens care products (contact lens care solution, contact lens preservation solution, contact lens cleaner); gynecological hygiene products (ladies anti-bacterial lotion, vagina lotion); other disposable sanitary products (tissue paper, sanitary napkin, cotton pad / paper / towel, hand / finger cot, mask, paper tableware, condom), etc. Among them, an important component of diapers, diapers (pads, paper), and urine-separating pads is the water-a...
