Abstract
The invention discloses a coated fabric containing antibacterial peptides and the preparation method, the surface of the fabrics are coated with coating agents containing antibacterial peptides. The preparation method comprises as follows: firstly, the antibacterial peptides are dissolved or dispersed into the coating agents at normal temperature to form finishing agents, then the fabrics are coated by the conventional rolling-baking method. The coated fabric containing antibacterial peptides has the advantages of broad spectrum antibacterial and bactericidal effect because the surface of the fabrics are coated with coating agents containing antibacterial peptides; no obvious influence on the appearance of the fabrics due to the thin coating layer.
Description
Technical field
The invention belongs to field of textiles, particularly a kind of coating fabric that contains antibacterial peptide and preparation method thereof.
Background technology
China most of area, the especially weather in our Zhejiang Province are relatively moister, are well suited for breeding and the growth of microorganism, and symptoms such as bedsore appear in regular meeting.On the other hand, in some public places, as hospital, just patient's purulence, blood, urine, the bed clothes that pollute with liquid body exudate etc. and mattress etc. become the place of all kinds of growth of microorganism, breeding, for hidden danger has been buried in nosocomialtion and infection.Therefore, the weaving face fabric with antibacterial functions prevents that for the mankind infringement of germ from playing an important role, and it can protect the people who uses textiles on the one hand, prevents the breeding of each bacterioid and fungi, the infection prevention transmission of disease; Can kill various moulds on the other hand, prevent that fiber from going mouldy and impaired.Nowadays, paid attention to by people gradually with the commodity that the antiseptic weaving face fabric is made, and, extensively and in depth be radiated the every aspect of life along with development of science and technology.
Human antibiotic work the earliest is to remove the bacterium that anchors in the weaving, adopts fully to wash and boil simple approach such as processing.The antibacterial deodourizing textiles that the eighties in 20th century, exploitation was used, great majority are processed into the arrangement of organic bactericides such as organic quaternary ammonium salt, imidazoles, the appropriate sodium of sulphur benzene, generally wash resistant not just provides against following baby of 2 one full year of life in Japan and uses this series products.Along with the development of development of science and technology and antibacterial agent, present anti-bacterial fibre mainly contains two big classes: a class is to be the inorganic anti fungus strain anti-bacterial fibre of representative to contain the synthetic fiber that nanoscale contains the silver zeolite anti-biotic material; Another kind of is with the anti-bacterial fibre of organic antibacterial agent by the blending method exploitation.Their production generally can be adopted two kinds of co-blended spinning method and finishing method processing.The co-blended spinning method is in fiber polymerization stage or spinning solution antiseptic to be added in the fiber, makes anti-bacterial fibre, then arrangement processing rule be with the antiseptic thermosetting on fiber, thereby reach the purpose of antibacterial deodourizing.
At present, the research and development to antibacterial fabric are both at home and abroad also deepening continuously, and a series of new product occurred.Developed chitin raw material as the weaving of big east, made the deodorization antibacterial gauze with CRABYARN.The antibiotic sanitary underwear trousers that Shanghai three rifle groups release use the refreshing technology of international famous Bao Er to weave, and can suppress the bacterium that underwear produce in dress effectively, remove peculiar smell and keep clean comfortable.Japan Megi company then develops and the clothes after being sewn into is carried out back processes, and gives the process technology of 12 kinds of functions such as antibacterial deodourizing, non-ironing, shielding of ultraviolet, water-absorbing fast-drying, antistatic.This process technology for cotton, closing clothes that multiple material such as fibre makes can both uniform processing, according to required additional function, clothes is immersed different medicaments, then with the clothes drying, by heat medicament is fixed on the clothes, also can uses various medicaments simultaneously.In addition, Hong Kong weaving is encouraged manufacturer's research, exploitation non-consumption textile product with the ready-made clothes industry, as is applied to the special antibiotic cloth of medical aspect, produces artificial blood vessel, heart sticking patch, soft-tissue patch etc.In a word, the requirement to antibacterial fabric comprises: have the high-efficiency broad spectrum antibacterial ability; Antibacterial effect is lasting, wash resistant; Heat-resisting, fast light, unsuitable decomposition failure, frivolous, saturating wet, comfortableness is good; Safe in utilization, be harmless to the health, do not cause pollution to environment.
In recent years, along with the development of nanometer technology, based on nano material to receive the weaving of (little) ground rice structural reform very prosperous with the research and development of macromolecular material, nanometer printing technology, and obtaining some achievements aspect the antibiotic textile product exploitation.Adopt nano-dispersed technology and anti-variable color technology as China scientific and technical personnel, successively successfully develop serial anti-bacterial fibres such as antibiotic polypropylene fibre, antibacterial dacron, anti-bacteria nylon, and produced and developed downstream product in batches." nano lamellar silver series inorganic antibiosis mildew-resistant fiber " technology of the auspicious exploitation of Beijing Saite and for example not only can be compatible with multiple fiber, and the product wash resistant of producing, and is all effective in cure to preventing gonorrhoea, hepatitis virus, acarid simultaneously.Use and utilize the underwear of nanoscale " antibiotic polypropylene fine denier low-stretch yarn " technological development of China Textile Academy development and socks etc. to issue the officers and men of the Chinese People's Liberation Army, it is good generally to react antibacterial effect.
The key of exploitation anti-bacterial fibre is to realize the requirement of machinability of antibiotic property, security and the application process of product in the fiber production simultaneously.And with the example that is processed as of the synthetic fiber that contain the silver zeolite anti-biotic material, its processing must be passed through the antibacterial matrices technology and could realize, the more important thing is, prevent the antiseptic discoloration problem, because the antiseptic of argentiferous generally can be in use or variable color in the moulded products; On the other hand, though the antibacterial action of organic antibacterial agent is strong, toxicity is higher, and has many organic antibacterial agents that other side effects are arranged, and as skin is had excitant etc., uses organic antibacterial agent to cause the danger of microorganism drug resistance and variation in addition for a long time.Therefore, adopting organic antibacterial agent to produce anti-bacterial fibre must be controlled in the safety interpolation amount ranges.
And antibacterial peptide is the general name that a class has Antimicrobially active polypeptides, and great majority have stronger killing action to gram-positive bacteria, and some then all works to Gram-negative bacteria and gram-positive bacteria.To some fungi, protozoan, especially drug tolerant bacteria there is killing action, and can selects killing tumor cell, suppress functions such as duplicating of hepatitis type B virus, therefore, most of antibacterial peptides have broad-spectrum bactericidal action.Compare with common antibiotic,, except antibacterium, can also act on fungi, protozoon, tunicary virus and cancer cell, can quicken effects such as immunity and wound healing process simultaneously because " antimicrobial spectrum " of antibacterial peptide is wider.
Summary of the invention
The purpose of this invention is to provide a kind of coated fabric that contains antibacterial peptide.
Purpose of the present invention also provides a kind of above-mentioned preparation method who contains the coated fabric of antibacterial peptide.
