Embodiment 1

[0032] The fiber is made of polyester filament, and the yarn type is 40 / 2 British count. The number of penetrations is 3, the reed number is 100, and the woven fabric after getting off the machine is sewn into a cylindrical shape with a diameter of 3 cm. After sterilization, it is for subsequent use.

Embodiment 2

[0034] The fiber is made of 14×2tex cotton yarn, and the fabric weave is designed as a double-layer weave composed of square weave and honeycomb weave. The warp yarn density is 432 yarns / 10cm, the weft yarn density is 250 yarns / 10cm, the number of penetrations per reed is 4, and the reed number 108, the woven fabric after getting off the machine is sewn into a cylinder with a diameter of 3 cm, and after sterilization, it is for subsequent use.

Embodiment 3

[0036] The fiber is made of 40 / 2 British count polyester staple fiber yarn. The fabric structure is designed as a double-layer structure composed of through-hole structure and crepe structure. The number is 3, the reed number is 100, and the woven fabric after getting off the machine is rolled into a cylinder with a diameter of 5 cm, tied up, sterilized, and set aside.

Abstract

The invention discloses a woven fabric carrier for cell immobilization and a preparation method thereof and belongs to the field of biological engineering. The preparation method of the woven fabric carrier comprises selecting a fiber from one of dacron, nylon, cotton and hemp; designing a fabric weave to enable the fabric weave to be a compound double-layer weave of random two of a basket weave, a honeycomb weave, a through hole weave and a crepe weave; selecting weaving parameters; and performing postprocessing, using a sewing or bundling method to process a woven fabric discharged out of a machine into a cylinder with the diameter of 2-7cm, and reserving after sterilization. The woven fabric carrier is used for immobilization of terephthalic acid (TA) degradation bacterium testosterone comamonas, and the degradation rate of the TA is greatly improved in comparison with a control sample which is not immobilized.

Description

technical field [0001] The invention belongs to the field of bioengineering, and relates to a preparation method of a woven fabric carrier, in particular to a preparation method of a woven fabric carrier used for cell immobilization. Background technique [0002] Cell immobilization technology refers to a technology that uses physical or chemical means to locate free cells in a specific space area and keep them active. At present, cell immobilization technology has rapidly developed into one of the research hotspots in bioengineering, and its application has involved many fields such as food, medicine, chemical industry, energy, and environment. [0003] The choice of carrier is the key to cell immobilization technology. The lack of biocompatibility, mass transfer performance, mechanical strength, processing and molding, cost and service life of the carriers currently used for cell immobilization restricts the further development of cell immobilization technology, and has b...
