Embodiment 1

[0064] Composite fabric and medical mask with built-in ZnO drug powder and its application practice

[0065] A composite fabric with built-in ZnO drug powder, the preparation method is as follows:

[0066] (1) Prepare the non-woven tape package of water-repellent and antibacterial layer 1

[0067] Use a silicone water-repellent finishing solution with a mass concentration of 10g / L and an opposite surface density of 30g / m 2 The 50 / 50 viscose / hemp medical antibacterial non-woven fabric is padded, and the cloth passing speed is 20m / min during padding; the cloth strips after padding are dried by SWA801-100 dryer, The drying temperature is 160°C, and then the BS-5300 fabric setting machine is used for steam setting treatment. The setting temperature is 150°C, and the setting time is 1min. The shaped fabric is cut into The 13cm wide non-woven fabric strip is wound in parallel on the cylindrical paper tube at a linear speed of 120m / min to obtain the non-woven fabric strip package o...

Embodiment 2

[0077] Composite fabrics and medical masks with built-in nano-silver nitrate powder and its application practice

[0078] A kind of composite fabric with built-in nano-silver nitrate powder, compared with embodiment 1, the difference is that, in step (3) preparation built-in anti-virus powder yarn woven fabric layer's strip wrapping process, adopts built-in The silver nitrate powder mass fraction is 40%, and the fineness is 40tex PP non-woven fabric strip coated silver nitrate powder composite yarn as the weft yarn, and the fineness is 21tex polyester sewing thread as the warp yarn, on the rapier loom The woven fabric with built-in powder material is made, and the woven fabric is cut into 10cm wide woven fabric strips by a strip cutting machine, and the edges of the woven fabric strips are sealed by thermal bonding to form a drug medical layer fabric cloth strips in rolls.

[0079] The rest of the steps are basically the same as those in Embodiment 1, and will not be repeated...

Abstract

The invention provides a composite fabric with built-in medicine powder, its production method and application. The composite fabric includes a water-repellent and antibacterial outer layer, a nanofiltration layer, an antibacterial fabric layer and a unidirectional moisture-conducting layer that are sequentially stacked, and the antibacterial fabric layer is a woven fabric layer containing a built-in drug powder yarn. With such a setting, on the one hand, the nano-filtration layer is used to block the invasion of nano-scale viruses from the outside; on the other hand, the moisture vapor of the virus on the population side is guided into the woven fabric layer to kill the virus through the one-way moisture-conducting layer. The invention adopts strip-type orderly stacking to produce composite fabrics, creatively integrates the integrated processing of non-woven, woven and knitted fabrics, and synergistically exerts the properties and functions of each fabric. The composite fabric prepared by the invention has good bactericidal, antibacterial, anti-virus functions and good sterilization persistence, and can prevent the virus on the composite fabric from returning to the air, solve the problem of secondary damage, and can be used for haze prevention, sterilization, Composite fabrics such as antibacterial or antivirus materials.

Description

technical field [0001] The invention belongs to the technical field of medical supplies and textiles, and in particular relates to a composite fabric with built-in drug powder and its production method and application. Background technique [0002] Public places, especially hospitals, are places where various infectious diseases are highly concentrated. In recent years, various respiratory infectious diseases such as SARS and highly pathogenic avian influenza are highly contagious and have the characteristics of fast transmission speed, high incidence rate and wide susceptible population. A large part of the transmission of the disease is due to the fact that the virus enters the air with the droplets produced by the cough or sneeze of the infected individual, suspends and flows in the air, and is inhaled into the lungs of healthy people, leading to infection. Wearing a mask can effectively avoid the spread and infection of germs transmitted through the air. On the one hand...
