Technical field

The present invention relates to biological medicine field of textiles, in particular to a kind of promotion skin tissue repair material film.

Background technique

Organizational project is that the cell seeding of cultured and amplified in vitro and a kind of biocompatibility is good and has certain space On the biomaterial of structure, culture makes cell mass propagation in vitro, then by their co-transplantations in required position, in body Inner cell continues to be proliferated, and biological support structure is then gradually degraded and absorbed, and as a result forms new histoorgan, to reach group Knit the purpose of reparation.Therefore, selecting suitable biomaterial and preparation method to construct tissue engineering bracket is Tissue Engineering Study Basis.Electrostatic spinning be it is a kind of formed under forceful electric power field action using polymer solution or melt injection stream carry out spinning processing Technique.Since electrostatic spinning technique is capable of forming nanometer to micron order fiber, the Nomenclature Composition and Structure of Complexes of extracellular matrix is imitated, is Cell provides good growing environment, therefore is the ideal method for preparing tissue engineering bracket.

Fibroin albumen is a kind of natural polymer fibrin, has nontoxic, biodegradable, good biocompatibility etc. Performance is suitable for bio-sensing, drug release material, the application fields such as tissue engineering material.Independent electrostatic spinning fibroin is It has been reported that, but pure silk cellulosic material has biggish brittleness, the inadequate disadvantage of mechanical strength hinders it in tissue engineering material side The research and application in face.Therefore, a kind of NEW TYPE OF COMPOSITE textile fabric film for promoting skin histology reparation of demand.

Summary of the invention

In order to solve the above technical problems, the present invention provides a kind of promotion skin tissue repair material films, using between warp knit Every knitting film as basement membrane, by MULTILAYER COMPOSITE, solve that single fibroin albumen nowoven membrane brittleness is big, mechanical strength is inadequate Problem.

In order to achieve the above objectives, technical scheme is as follows: a kind of promotion skin tissue repair material film, including fibre Dimension spunlaid nonwoven film, warp-knitted spacer knit film, chitin dressing layer and fibroin albumen dressing layer；The spunlaid nonwoven film, warp It knits film, chitin dressing layer and fibroin albumen dressing layer and is cascading from inside to outside in volume interval；The warp-knitted spacer knits film The film-form warp-knitted spacer fabric as made of the braiding of super fine denier PLA fiber yarn；The fibre spinning nowoven membrane is by seaweed fibre Dimension nonwoven membrane made of electrostatic spinning knits film surface spinning in the warp-knitted spacer；The chitin dressing layer is by first Shell cellulose fiber spinning solution knits non-woven film layer structure made of film surface electrostatic spinning in the warp-knitted spacer；The fibroin albumen Dressing layer is as fibroin albumen spinning solution non-woven film layer structure made of the chitin dressing layer surface electrostatic spinning.

As a preferred solution of the present invention, the super fine denier PLA fiber yarn is formed by nanometer PLA fiber spinning.

As a preferred solution of the present invention, the warp-knitted spacer knit film with a thickness of 0.12-0.25mm.

As a preferred solution of the present invention, the fibre spinning nowoven membrane with a thickness of 0.05-0.10mm.

As a preferred solution of the present invention, honeycomb hole is densely covered with inside the fibre spinning nowoven membrane.

As a preferred solution of the present invention, polytetrafluoroethyl-ne is compounded in the outer surface of the fibre spinning nowoven membrane Alkene nanometer film layer.

Through the above technical solutions, the beneficial effect of technical solution of the present invention is: structure of the invention is reasonable, can using biology Composite material film made of degradable material, structural strength is good, has good biocompatibility, and soft-touch is covered in skin Wound surface, moisturizing good permeability, can antibacterial anti-inflammatory, promote skin histology to accelerate recovery from illness, using effect is good.
