Preparation method of close-fitting elastic pants type paper diaper

Abstract

The invention relates to the field of hygienic products, and provides a preparation method of a close-fitting elastic pants type paper diaper, which solves the problem that pull-pants in the prior art are easy to fall and leak after absorbing liquid, and comprises the following steps: preparing an outer clothes layer, preparing an absorber, fixing the absorber on the outer clothes layer, welding the absorber into a pants type structure, and cutting the pants type structure into single products; the preparation of the outer clothes layer comprises the following steps: (1) uncoiling an outer-layer non-woven fabric, carrying out on-line transmission, defining the outer-layer non-woven fabric to have a transverse direction along the transmission direction and a longitudinal direction vertical to the transmission direction, enabling the outer-layer non-woven fabric to have a front area, a middle area and a rear area which are sequentially connected along the longitudinal direction, and carrying out on-line compound waistline rubber bands on the front area and the rear area of the outer-layer non-woven fabric, glue is applied to the waistline rubber band during compounding; (2) applying an S rubber band; (3) compounding the inner-layer non-woven fabric; and (4) compounding an elastic material layer with transverse flexibility.

Description

technical field [0001] The invention relates to the field of sanitary products, in particular to a method for preparing close-fitting elastic trouser-type paper diapers. Background technique [0002] Pants-type diapers generally include an outer clothing layer and an absorbent body arranged in the outer clothing layer. The outer clothing layer is usually of a one-piece type or two-piece type, and is fixedly connected to the front end and the rear end of the absorbent body. The lateral sides are welded to form a closed structure with leg openings and waist openings. Pants-type diapers with this traditional structure tend to fall after absorbing a large amount of urine, especially when the baby is in a crawling or standing state. It is easier to fall off, and in addition, urine is easy to leak from the front and rear ends of the absorber.

[0002] Pants-type diapers generally include an outer clothing layer and an absorbent body arranged in the outer clothing layer. The outer clothing layer is usually of a one-piece type or two-piece type, and is fixedly connected to the front end and the rear end of the absorbent body. The lateral sides are welded to form a closed structure with leg openings and waist openings. Pants-type diapers with this traditional structure tend to fall after absorbing a large amount of urine, especially when the baby is in a crawling or standing state. Easier to shed, plus urine tends to leak from the front and back of the absorber

[0003] Chinese Patent No. 201920461106.X discloses an elastic waist structure, including a front waist and a back waist. The outside of the front waist and the back waist is provided with an outer layer of non-woven fabric, and the inside is provided with an inner layer of non-woven fabric. Waist elastic bodies are arranged between the cloth and the inner layer of non-woven fabric, and the elastic bodies are arranged at intervals. The elastic bodies in the front waist and / or back waist are arc-shaped. In addition, a kind of elastic waist structure is provided Pull-up pants have a good close-fitting effect by setting the crotch elastic body in the crotch area, but due to structural design defects, pull-up pants with this structure are prone to front leakage and back leakage after absorbing urine

This product improves the overall fit and anti-drop effect by setting elastic bands at the crotch, and improves the anti-side leakage effect by setting elastic bands on both lateral sides of the absorbent diaper. Leakage did not carry out targeted improvement design
