The one or more of which combination of fiber, ABS fibers, PE/PET fibers, PE/PP fibers.
A kind of preparation method of wound dressing comprising a kind of above-mentioned wound dressing, a kind of system of wound dressing
Preparation Method includes the following steps：
S1, offer composite fibre in, gelatinous fibre content is 50% ~ 100%, and textile fabric content is that 0% ~ 50%, thermoplasticity is fine
Dimension hplc is 0% ~ 20%, the gelatinous fibre, textile fabric and thermoplastic fibre is carried out blended；
S2, will be blended after wound dressing it is perverse into the hand-manipulating of needle, needle thorn after enter next step；
S3, wound dressing of the needle after perverse carry out to rolling and molding, temperature is not less than 110 DEG C when hot rolling.
Beneficial effects of the present invention are：The wound dressing is a kind of composition, and preparation method is simple, the wound dressing group
Close after object contact human body wound fluid can gelation, and while removing after use can keep the integrality of dressing.
Specific implementation mode
A kind of wound dressing provided in an embodiment of the present invention, by containing gelatinous fibre, textile fabric, two kinds of thermoplastic fibre
Or two or more fiber compositions, the gelatinous fibre content are 55% ~ 100%, textile fabric content is 0% ~ 50%, thermoplastic fibre
Content is 0% ~ 20%；The wound dressing grammes per square metre is 65 ~ 200g/cm2, and thickness is 0.5 ~ 5.0mm, and liquid absorption amount is not less than 10g/
0.9% saline solution of 100cm2.
In a kind of embodiment, the gelatinous fibre is sodium carboxymethyl cellulose fibre, chemically-modified cellulose fiber, pectin
The one of which of fiber, alginate fibre, chitin fiber, Hyaluronan fibers, polysaccharide fiber or gummy fiber.
In a kind of embodiment, the cellulose fibre is the substitution at least 0.05 carboxymethyl of every glucose unit
Degree.
In a kind of embodiment, the gelatinous fibre is the absorbability at least 2 gram 0.9% saline solution of every gram of fiber.
In a kind of embodiment, the textile fabric is, tencel fiber, viscose rayon, nylon fiber, polyester fiber, polyamide fibre
