Description
Technical field
The present invention relates to medical textile field of material technology, and in particular to a kind of medical textile material and its preparation side
Method and application.
Background technology
The material used in medical textile currently on the market mainly has two categories below：PE laminations non-woven fabrics and PE overlay films without
Woven fabric, its purpose and function are barrier bacterium and virus, to protect doctor and patient both sides' safety.The structure of PE lamination non-woven fabrics
For upper and lower two layers, upper strata is non-woven fabrics, and lower floor is PE films.Its production technology is to pass through screw rod after PE pellet meltings are formed fluid
Extrude and uniformly apply to scrape with glued membrane head and form PE protective films after cooling on non-woven fabrics.The structure of PE overlay film non-woven fabrics is upper and lower
Two layers, upper strata is non-woven fabrics, and lower floor is PE films.Its production technology is using pressure sensitive adhesive or hot melt adhesive as adhesive, by PE films
Pass through combination process pressing and forming with non-woven fabrics.The PE laminations non-woven fabrics and PE overlay films non-woven fabrics of prior art production are main to be lacked
It is no moisture-inhibiting function to fall into, manufactured operating coat, operating cap, sheet, hole towel, and human body is coated or contacted during use, human body
Sweat and moisture can not discharge, and cause extremely uncomfortable.It is a kind of non-porous film, liquid water and moisture that this defect, which is primarily due to PE films,
Can not be by, thus can be permeated with waterproof resistant to blood, but therefore do not have moisture-inhibiting perspiration functions yet.Therefore, it is also desirable to develop new
The medical textile material of type.
The content of the invention
For in the prior art the defects of, present invention aims at provide a kind of medical textile material and its preparation side
Method, with by using the high moisture-inhibiting performance of thermoplastic elastomer films, the medical textile material with three-decker being prepared
Expect ensureing waterproof, resistant to blood, anti-alcohol and obstructing outside the safeguard function of bacterial virus, moreover it is possible to rapid to absorb what human body was formed
Sweat, makes medical staff put on the medical surgical gown processed using this medical textile material, Medical operation cap, medical protection
When clothes or medical isolation clothes, the dry and comfortable comfortable of body can be kept, mitigates fatigue strength caused by work, improves procedure efficiency and matter
Amount.
To achieve the above object, technical solution provided by the invention is：
In a first aspect, the present invention provides a kind of medical textile material, medical textile material includes three layers, from up to
Under be followed successively by polypropylene (PP) nonwoven layer, thermoplastic elastomer films layer (TPE) and polypropylene (PP) nonwoven layer；Wherein, it is hot
The thickness of thermoplastic elastic film layer is 0.008~0.01mm.It should be noted that thermoplastic elastomer films, i.e. TPE Waterproof Breathables
Film is a kind of novel high polymer waterproof material, with polyurethanes (TPU) for main material, imports hydrophilic group, film surface
Pore-free, therefore can have excellent infiltration energy.Because there is hydrophilic group, it is conducted through by the attached moisture absorption of absorption-desorption
Journey, so that with excellent water vapour permeability.The power of its moisture-inhibiting function comes from：Concentration difference, temperature difference and pressure differential.TPE prevents
After the compound PP non-woven fabrics in water moisture permeable membrane both sides, formed three-decker, the TPE waterproof humidity-permeant film thin to dynode play protection and
Supporting role so that waterproof resistant to blood splash function can reach PE (polyethylene) the lamination non-woven fabrics property identical with overlay film non-woven fabrics
Can index.The thickness of TPE film is 0.008~0.01mm, is that not only can guarantee that water resistance at present but also to take into account water vapour permeability optimal
