Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the existing diapers can only meet the basic absorption function, but when the user uses the diapers, the air permeability is not good, and the urine contains toxins. Due to the poor antibacterial performance, it is easy to be infected with bacteria. In order to solve the problem of skin inflammation, a high-elastic adult diaper that is easy to wear is proposed

Abstract

The high-elasticity adult diaper convenient to wear comprises a diaper body, the diaper body is provided with a surface layer, a flow guide layer, an absorption core layer and a back layer from top to bottom, and the surface layer is made of modified fibers; the preparation process of the modified fiber comprises the following steps: firstly, reacting chloroethylamine hydrochloride with pyridine to produce an intermediate 1, and then substituting a chlorine atom on cyanuric chloride with 2, 2, 6, 6-tetramethyl piperidylamine to obtain an intermediate 2; finally, the intermediate 1 is used for replacing another chlorine atom on cyanuric chloride, an intermediate 3 is prepared, and the intermediate 3 has good antibacterial performance; then, the intermediate 3 reacts with caprolactam to replace the last chlorine atom, and an intermediate 4 is obtained; preparing a polyether amide polymer from the intermediate 4, sebacic acid, 6-aminocaproic acid and polyethylene glycol through a one-step method; the adult diaper prepared by the invention has good antibacterial performance.

Description

technical field [0001] The invention belongs to the technical field of diapers, in particular to a high-elastic adult diaper that is easy to wear. Background technique [0002] Diapers are disposable products that can be discarded after a single use. It is made of non-woven fabric, toilet paper, fluff pulp, polymer water-absorbing resin, PE film, rubber band and other materials. There are two types for children and adults. [0003] Chinese patent CN107519522B discloses a baby diaper and its preparation method; the baby diaper provided includes a diaper body, and the diaper body is respectively provided with a surface layer, a flow guide layer, an absorbent core layer and a back layer from top to bottom, The surface layer is made of moxa, Lyocell fiber and ES fiber; the flow guide layer is made of ES fiber with a thickness of 6D reinforced by hot air; the absorbent core layer includes composite fiber, super absorbent resin and fluff pulp , the weight ratio of the composite...
