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...
