Problems solved by technology

[0004] However, the above non-woven fabrics only consider hydrophilicity, a single characteristic required in use. Non-woven fabrics can absorb and carry more disinfectant after they are hydrophilic, and it is indeed convenient for sterilization and disinfection, but because hydrophilicity is not Control, so that the transfer rate of the disinfectant from the non-woven fabric to the surface to be sterilized is low, increasing the amount of disinfectant and reducing the disinfection efficiency of medical devices; at the same time, after the disinfection is completed, the residual liquid of the disinfectant is more and Due to the low volatilization efficiency, the disinfectant will remain on the surface of the object to be sterilized for a long time, and it needs to be wiped clean or wait for a long time, which reduces the turnover efficiency of medical equipment, etc., and increases the possibility of corrosion of the object to be sterilized by the disinfectant sex

Embodiment 2

[0039] The multi-layer non-woven fabric for disinfection is in the shape of a rectangular sheet as a whole, and the edges are locked by stitching. This product is used for the disinfection of the surface of surgical instruments, including the disinfectant solution adsorption transfer layer 1, the hydrophobic layer 2 and the disinfectant recovery layer 3, which are sequentially stacked. Based on the measurement method in GB / T 24218.6-2010, the disinfectant solution adsorption transfer layer The liquid absorption capacity X of 1 is 400%, the liquid absorption capacity Y of the disinfectant recovery layer 3 is 800%, and the liquid absorption capacity of the hydrophobic layer 2 is 5%.

[0040] The non-woven fabric in the disinfectant absorption transfer layer 1 is quantitatively 20g / m 2 , the hydrophilic permeation speed is 7s, and the hydrophilicity index is 3(mJ 1 / 2 / m), the thickness is 1000 μm; the non-woven fabric in the disinfectant recovery layer 3 is quantitatively 20g / m ...

Embodiment 3

[0042] The multi-layer non-woven fabric for disinfection is in the shape of a rectangular sheet as a whole, and the edges are locked by pressing. This product is used for the disinfection of ultrasonic probes connected to the rubber pipeline of the monitor, including the disinfectant solution adsorption transfer layer 1, the hydrophobic layer 2 and the disinfectant recovery layer 3, which are sequentially stacked. The liquid absorption X of the adsorption transfer layer 1 is 300%, the liquid absorption Y of the disinfectant recovery layer 3 is 600%, and the liquid absorption Y of the hydrophobic layer 2 is 2%.

Abstract

The invention relates to the field of non-woven fabrics, and aims to provide a multi-layer non-woven fabric for disinfection and a use method thereof. The multi-layer non-woven fabric for disinfection comprises a disinfectant adsorption transfer layer, a hydrophobic layer and a disinfectant recovery layer which are sequentially stacked, and the disinfectant adsorption transfer layer and the disinfectant recovery layer are made of hydrophilic non-woven fabric; the hydrophilicity of the disinfectant adsorption transfer layer is smaller than the surface hydrophilicity of the object to be disinfected, and the hydrophilicity of the disinfectant recovery layer is larger than the surface hydrophilicity of the object to be disinfected. The middle layer of the product is the hydrophobic layer, and the disinfectant cannot be directly adsorbed and transferred on the hydrophilic non-woven fabric layers on the two sides, so the situation that the use of the disinfectant recovery layer is affected due to excessive absorption and waste of the disinfectant is avoided. The hydrophilicity of the surface of a disinfected object is between the disinfectant adsorption transfer layer and the disinfectant recovery layer, so that the disinfection operation is effectively realized, the disinfectant consumption can be reduced, the residue can be reduced, the disinfection efficiency can be improved, the corrosivity can be reduced, and the technical feasibility and the economic value are very good.

Description

technical field [0001] The invention relates to the field of non-woven fabrics, in particular to a multilayer non-woven fabric for disinfection and a use method. Background technique [0002] Nonwoven Fabric (Nonwoven Fabric), also known as nonwoven fabric, directly uses polymer slices, short fibers or filaments to form fibers through airflow or machinery, and then undergoes hydroentanglement, needle punching, or hot rolling reinforcement, and finally passes through The non-woven fabric formed by finishing is called cloth because of its appearance and certain properties. Non-woven fabrics have broken through the traditional textile principles, and have the characteristics of short process flow, fast production rate, high output, low cost, wide application, and multiple sources of raw materials. Non-woven fabrics are soft, breathable, non-lint-free, strong and durable, chemical-resistant, anti-bacterial, non-toxic and non-irritating, close in vertical and horizontal strength...
