Description
Technical field
The present invention relates to the textile surface modification treatment technology, be specially a kind of method that adopts monad dacron to be carried out bio-modification.
Background technology
Terylene (PET) fiber has good physical and mechanical properties and chemical stability, but it is as taking fiber, exists that gas permeability is poor, water imbibition weak, easily produce static, dyeability is relatively poor and dress has deficiencies such as feeling of heaviness.In order to overcome the above-mentioned shortcoming of polyster fibre, make it have hydrophily and antistatic behaviour preferably, people carry out modification to polyster fibre.Up to now, many scholars and research institution have carried out number of research projects, and the method for application can reduce chemical modification, physical modification and bio-modification three major types method.Common chemical modification method is the alkali treatment method, the processing waste water that this method forms, and alkali concn is higher, and contains a large amount of oligomer and monomer, and environment is existed than havoc; Physical modification method is mainly the Cement Composite Treated by Plasma technology, and its cost is higher, and treatment effect is still obvious inadequately, is in the laboratory research stage, can not large-scale production; Biological modified method is handled research extensively, mainly is to adopt the lipase of extensive stockization or adopt microorganism induction to produce lipase, opens the ester bond in the big molecule of PET, thereby produce an amount of hydroxyl and carboxyl, improve the hydrophily of fabric, antistatic behaviour, performances such as pilling.But because PET chemical constitution closely, higher degree of crystallinity and vitrification point, microorganism and enzyme are difficult to be deep into fiber or fabric, and therefore, the bio-modification effect remains further raising.
Present used dacron bio-modification all adopts the microorganism of lipase or generation lipase to carry out, and it induces substrate mostly to be ester bond.Because the selectivity of lipase makes its modifying function to dacron be confined to the hydrolysis of ester bond, terylene chemical constitution closely in addition, higher degree of crystallinity and vitrification point cause modified effect not obvious.In the scope of applicant's retrieval, the relevant terylene monomer that contains phenyl ring that adopts is as inducing substrate, and the document of inducing Comamonas testosteroni to produce oxidizing ferment modified dacron fabric does not appear in the newspapers as yet.
Summary of the invention
Depend on the limitation of lipase at present used dacron biological modified method, the technical problem that quasi-solution of the present invention is determined is, a kind of method of dacron bio-modification is provided, and this method adopts induces monad to produce oxidasic method dacron is carried out modification.Technology is easy, and modified effect is obvious.
The technical scheme that the present invention solve the technical problem is, design a kind of method of dacron bio-modification, this method adopts induces the oxidasic method of Comamonas testosteroni (Comamonas testosteroni) generation that dacron is carried out modification, mainly may further comprise the steps:
(1). culture of strains: Comamonas testosteroni at 30-37 ℃, is cultivated 12-18h in the inclined-plane solid medium, be stored in 4 ℃ of refrigerators standby; Described solid culture based component is: potassium dihydrogen phosphate 3g/L, sodium hydrogen phosphate 7g/L, ammonium chloride 1g/L, sodium chloride 5g/L, magnesium sulfate 0.25g/L, agar powder 18g/L and substrate terephthalic acid (TPA) 3g/L;
