Description
Technical field
The present invention relates to technical field of textile processing, more particularly to a kind of sub-micron fibers across scale ring ingot cored online
Spinning apparatus and method.
Background technique
Electrostatic spinning be it is currently the only can mass spin the universal methods of continuous sub-micron fibers, it is easy to operate, can
Implementation is strong.By the diameter of the standby sub-micron fibers of electro-spinning usually in 100-1000nm, fibre dimensions are small, specific surface area
Height, and fiber morphology and component can be regulated and controled by the flexible choice of spinning technology parameter and polymer, make Static Spinning sub-micro
Rice fiber becomes the research hotspot of fibre science and engineering field, and is widely used in filtering, the energy, biomedicine, urges
The fields such as change, Waterproof Breathable, water-oil separating.But since the diameter of Static Spinning sub-micron fibers is small, crystallinity is low, leads to it absolutely
Mechanics strength is very poor, far below the tension failure strength of conventional staple and chemical long filament, thus brings sub-micron fibers system
Product are easy to wear in the process of processing and using, and the outstanding problems such as structural stability difference seriously limit its commercial applications.
In view of the above-mentioned problems, a kind of current way is that Static Spinning sub-micron fibers are processed into pure spinning sub-micron fibers yarn

Fiber coats the complex yarn and micro nanometer fiber blended yarns of short fibre, mentions for the mass preparation of micro nanometer fiber complex yarn
A new thinking is supplied, but since related resultant yarn method and device do not control the deposition of nanofiber effectively
System, so that nanofibres deposit disorder, it is difficult to be effectively embedded in yarn body, so as to cause the knot of micro nanometer fiber complex yarn
Structure is uncontrollable, influences yarn property；In addition, the nanofiber for being coated on yarn body surface face is equally existed in processing and use process
In the easy to wear and critical defect that falls off.
