Description
Technical field
The present invention relates to the fiber production field, particularly a kind of antibacterial olybuthylenesuccinatfibre fibre.
Background technology
Raising along with people's living standard, requirement to weaving face fabric is also more and more higher, original various chemical fibre series products has been difficult to satisfy people's demand, various tencels are by continuous research and development application, the unique advantage of tencel has brought up functionalization, comfortableization and superior of weaving face fabric, the tencel advantage is many, and the added value of creation is also high certainly.
A kind of as in the tencel of biodegradable polyester fiber because the factor of environmental protection just is being subjected to people's attention, continually develops the fiber that makes new advances, be applied to medical, take, numerous areas such as fishery, building, health, decoration, industrial treatment.Wherein poly butylene succinate can have industrial prospect by chemical synthesis, is the focus of studying at present.But biodegradable polyester fiber also exists the shortcoming of self, and fusing point is low, and intensity is little, and the synthetic difficulty of high molecular weight polyesters limits its processing and application, need be by modification to improve performance.
Summary of the invention
In order to satisfy the many-sided needs of people to weaving face fabric, continually develop tencel, we consider and utilize the novel degradable poly butylene succinate that by modified method, the research and development tencel enlarges its range of application.
