Description
Technical field
The present invention relates to textile technology field, more particularly to scribbled, and in particular to a kind of wear-resisting heat resistanceheat resistant scribbled
And preparation method thereof.
Background technology
In recent years, due to shortage of resources and environmental protection the problems such as become increasingly conspicuous and the enhancing of people's environmental consciousness and
The in-depth of sustainable development idea, the research and application of natural fiber receive more and more attention, and acid fiber by polylactic has same
The similar physical characteristic of PET, not only with high crystalline, also with the same transparency；It is and highly crystalline due to it
Property and high-orientation, so as to have high-fire resistance and high intensity, and without special equipment and operating procedure, using adding for routine
Work technique can carry out spinning, after its product is discarded in soil or seawater through microbial action can be analyzed to carbon dioxide and
Water, during burning, poison gas will not be distributed, will not be polluted, is a kind of ecological fiber of sustainable development；CUP is a kind of
Regenerated celulose fibre, because section is rounded, no skin-core structure, fiber can bear high elongation, and obtained monofilament is thinner, institute
Soft with fabric, gloss is soft, there is silky touch；Cotton fiber is the primary raw material of China's textile industry, and it is in textile fabric
In account for critically important status, cotton Products moisture absorption and good permeability, soft and warming, cotton fiber has good spinning performance,
But in high temperature, cotton wax easily melts, so cotton is easily around roller, around rubber roll.
Different types of fiber blend is natural in field of textiles extensive use, general as the common method for improving fibre property
Fiber and high performance fiber blend, the application field of natural fiber can not only be expanded, lift natural fiber added value, while
