Abstract

The embodiment of the invention provides a biodegrading agent, a biodegradable fiber and their preparation methods. Materials for the biodegrading agent provided by the embodiment of the invention areeasy to obtain, the design is reasonable, the effect of PBST (phosphate buffered solution with tween 20) is to provide toughening modification, polylactic acid is a carrier to monosaccharides and aldoses, the function of the monosaccharides and aldoses is to attract bacteria and provide energy for bacteria, the biodegrading agent is simple to prepare and is easy to use, the biodegradation of thefiber can be accelerated just by adding the biodegrading agent without changing production line equipment of fibrils, no adverse effect is caused on fibrils, and the degradation rate of the fiber in the soil can be controlled just by changing the addition amount of the biodegrading agent as required. According to the biodegradable fiber provided by the embodiment of the invention, the preparationprocess is not complex, the existing fiber production line equipment does not need to be changed, and the problem that traditional PET and PBT fibers cannot be degraded due to the benzene ring structure in the molecular chains is solved.

Description

technical field [0001] The invention belongs to the technical field of polyester fiber, and in particular relates to a biodegradation agent, a biodegradation fiber and a preparation method. Background technique [0002] A variety of polymer material products have brought unprecedented convenience and comfort to our lives. At the same time, organic polymer waste generated by industry and daily life has become an important source of environmental pollution today. Synthetic fiber waste is an important component. Traditional incineration and landfill methods harm the environment and occupy land resources. Therefore, it is necessary to start from the source and develop and promote biodegradable synthetic fibers. [0003] Biodegradable polymer materials refer to polymers that can be completely degraded after being eroded by organisms in nature, such as bacteria, fungi, and algae. There are currently two different ways to make polymer materials degradable by microorganisms. One w...
