Problems solved by technology

Through the raw material formula and the dosage of each raw material of the present invention, and in conjunction with the production method, especially the finishing step in the production method, under the premise of ensuring the diversion effect, better softness and fluffy effect of the non-woven fabric are realized. The non-woven fabric can replace the fluffy cotton, because the non-woven fabric produced by the present invention is softer and thinner than the fluffy cotton, and at the same time, the drainage effect and the hydrophilic effect are better than the fluffy cotton, so it can ensure high comfort and drainage Under the premise of good effect, the production of ultra-thin core body solves the current problem that fluffy cotton cannot be used to make ultra-thin core body

Abstract

The invention discloses a production method of fluffy diversion non-woven fabric. The production method comprises the steps of (1) mixing raw materials to obtain a mixture, wherein the raw materials comprise the following components in percentages by weight: 92-96% of polypropylene and 4-8% of a propenyl plasticizer; (2) extruding and melting the mixture to form a hot melt; (3) spinning the hot melt; (4) cooling filaments sprayed in the step (3) to obtain primary filaments, drawing the primary filaments through an airflow to obtain fiber, and lapping the fiber to form a fiber web; (5) carryingout hot rolling on the fiber web prepared in the step (4) to obtain non-woven fabric; (6) carrying out after-finishing on the non-woven fabric to obtain fluffy non-woven fabric; and (7) carrying outhydrophilic and drying treatment on the fluffy non-woven fabric obtained in the step (6) to obtain a finished product. According to the production method, fluffy cotton can be replaced, and an ultrathin core body is manufactured, so that the problem that the ultrathin core body cannot be manufactured through the fluffy cotton at present is solved.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to a non-woven fabric applied to the core of diapers and a production method thereof. Background technique [0002] At present, baby diapers, pull-up pants, adult diapers, etc. generally adopt core structure instead of traditional fluff pulp and diversion layer materials. The liquid is diffused and distributed, so that the liquid leaves the user's skin quickly, keeping the skin dry and comfortable. [0003] The current core structure generally includes a covering material on the surface layer and a fluffy flow-guiding layer covered by the covering material. Water-absorbing materials are mixed in the fluffy flow-guiding layer. The existing covering material is non-woven fabric, which is fluffy. The diversion layer is fluffy cotton, and the water-absorbing material is polymer water-absorbing resin. The above-mentioned core structure uses non-woven fabric and fluffy cotton ...
