Disposable three-layer composite material for medical sheets and method for preparing disposable three-layer composite material

Abstract

The invention provides a disposable three-layer composite material for medical sheets and a method for preparing the disposable three-layer composite material. The disposable three-layer composite material comprises a first non-woven fabric layer, a second non-woven fabric layer and a thin film layer. The thin film layer is arranged between the first non-woven fabric layer and the second non-woven fabric layer, the upper surface of the thin film layer is combined with the first non-woven fabric layer by a first adhesive layer, and the lower surface of the thin film layer is combined with the second non-woven fabric layer by a second adhesive layer; the first non-woven fabric layer is made of impregnated non-woven fabrics, the second non-woven fabric layer is made of PP (polypropylene) non-woven fabrics, the thin film layer is made of polyethylene films, the gram weight of the first non-woven fabric layer is 1.5-2 times the gram weight of the second non-woven fabric layer and is 1.1-1.5 times the gram weight of the thin film layer, and the gram weight of the second non-woven fabric layer is 0.6-0.8 times the gram weight of the thin film layer. The method for preparing the disposable three-layer composite material includes steps of A) raw material purchasing, B) acceptance warehousing, C) fetching and stirring, D) thin film production, E) thin film acceptance inspection, F) combining and mass production, G) slitting and winding, H) acceptance inspection and packaging and I) warehousing and delivery.

Description

technical field [0001] The invention belongs to the technical field of medical composite materials, and relates to a single-use medical single-layer three-layer composite material and a preparation method thereof. Background technique [0002] With the continuous improvement of medical level, hospitals pay more and more attention to the prevention and control of infection risk during operation, and medical drape is widely used. The liquid exuded during the operation can be absorbed by the drape, and at the same time, it can act as a barrier to bacteria and liquid, so as to reduce the pollution to patients, medical staff and the environment during the operation. [0003] At present, in medical operations, most of the medical drapes used in long-term and large-volume operations are made of PE plastic film and impregnated cloth composite materials or spun-bonded non-woven fabrics, which have poor anti-leakage effects. During the use of the hospital bed, the bed will be pollute...
