Medical sanitary non-woven fabric

Abstract

The invention belongs to the technical field of non-woven fabrics, in particular to a medical sanitary non-woven fabric. The fabric comprises a surface layer, an intermediate layer and a contact layer, wherein the surface layer is arranged above the intermediate layer; the contact layer is arranged under the intermediate layer; the surface layer is a non-woven fabric; the contact layer is a non-woven fabric; the intermediate layer is high-molecular water-absorbing resin. The medical sanitary non-woven fabric has a simple structure, and the production process is simple and implementable; besides, the use of an adhesive is omitted, the production cost is effectively reduced, strength of the product is improved by pressed lines formed by ultrasonic pressing, dislocation and aggregation of composition of the product can be avoided, and performance of the product is ensured.

Description

technical field [0001] The invention belongs to the technical field of non-woven fabrics, in particular to a medical and sanitary non-woven fabric. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of oriented or random fibers. It is called cloth because of its appearance and certain properties; the current use of non-woven fabrics still exposes some problems. When non-woven fabrics are used, excessive liquid will permeate the non-woven fabrics, resulting in liquid leakage and pollution. , in view of the problems exposed in the current use of non-woven fabrics, it is necessary to improve and optimize the structure of non-woven fabrics; [0003] There are some solutions in the prior art. In the Chinese patent with the application number CN201910310006.1, the side surface of the fabric is provided with a water guide groove and a water-permeable blind hole.

[0003] There are some solutions in the prior art. In the Chinese patent with the application number CN201910310006.1, the side surface of the fabric is provided with a water guide groove and a water-permeable blind hole. The rapid flow spreads out, and the absorbent cotton guides the liquid in the vertical direction, so that the liquid quickly reaches the inside of the non-woven fabric body, and is absorbed and stored by the hydrophilic cotton and water-absorbing gel particles. The water-proof membrane and the polypropylene water-proof layer Avoid liquid penetration to the bottom of the non-woven fabric body, effectively avoiding liquid leakage, but the structure and production process of the finished non-woven fabric in this scheme are more complicated, and the hydrophilic cotton and water-absorbing gel used to absorb the liquid are squeezed, The absorbed liquid is squeezed out, causing the problem of secondary pollution. At the same time, the produced non-woven fabric has almost no air permeability; the Chinese patent application number CN201711471261.1 includes SMS spunbond melt-blown non-woven fabric, so The SMS spunbond melt-blown nonwoven fabric comprises the first SMS spunbond melt-blown nonwoven fabric and the second SMS spunbond melt-blown nonwoven fabric fixedly connected to each other, and the first SMS spunbond melt-blown nonwoven fabric and the second SMS spunbond melt-blown nonwoven fabric are Two SMS spunbonded meltblown non-woven fabrics are fixed with polymer water-absorbent resin SAP, hot melt adhesive for fixing polymer water-absorbent resin SAP or SMS spunbond melt-blown non-woven fabrics, and the polymer water-absorbent resin SAP is the surface layer The polymer water-absorbent resin that wraps the shell formed by curing the water-permeable polyurethane emulsion fundamentally solves the industry problem that the polymer cannot be used in direct contact with the hot melt adhesive, and at the same time, the absorption efficiency of the absorbent material is effectively improved and the resource utilization rate is high. , more environmentally friendly, and at the same time, the preparation method of the absorbent material is continuously controllable. The absorbent material produced in this scheme can effectively absorb liquid and prevent liquid penetration at the same time, but the production method is also relatively complicated, and the absorbent material produced has poor antibacterial and antibacterial ability The problem
