Description

Device and method for preparing bi-component fiber based on melt differential centrifugal spinning
Technical Field
The invention relates to a micro-integral lamination-based melt centrifugal spinning device and method, and belongs to the field of centrifugal spinning.
Background
Bicomponent fibers are fibers which are made up of two different polymers which are combined together in some manner. Bicomponent fibers have the properties and advantages of two polymers, one polymer to provide its desired physical properties and the other polymer to perform a specific function, and thus are widely used in filtration, optics, electrical conductivity, flame retardancy, etc.
Chinese patent CN101798714B discloses obtaining bicomponent fiber by extrusion molding using a spinneret plate, the spinneret plate includes a plurality of spinneret orifices, the spinneret orifices include skeleton extrusion orifices arranged in a radial manner and split extrusion orifices spaced by the skeleton extrusion orifices, the nascent fiber includes a skeleton portion extruded from the skeleton extrusion orifices and split portions extruded from the split extrusion orifices. The bicomponent fiber prepared by the method has high efficiency and good uniformity; however, since the fiber is simply extruded without drawing with an external force, the fiber diameter is large.
Chinese patent CN104797749B discloses an apparatus for preparing bicomponent fibers using a two nozzle spinneret. This method can produce bicomponent fibers of various structures, but the bicomponent fibers are not easily combined by having two jets to eject them.
The melt centrifugal spinning technology is a method in which polymer melt is spun out of fine holes by overcoming surface tension with the help of centrifugal force generated by a high-speed rotating device, and fibers are formed after the melt is solidified.
US20090280325a1 discloses different types of spinning apparatus, including spinning disk with four-channel flow guide slot, injector with different nozzle shape and spinneret orifice using metal grid as spinning device, etc., the conventional materials such as PAN, PEO, PS and ABS are tried and fiber with diameter of about 1 micron is obtained, but the implementation is directed to needle and small hole, the spinning efficiency is low.
Chinese patent CN104674360B proposes that superfine fiber is formed by utilizing airflow assistance, thinning, differentiating and refining under the action of centrifugal force, high-speed airflow and adhesive force of melt on a conical surface, and throwing out at high speed. The method has high fiber preparation efficiency, but the fibers are thrown out in the circumferential direction and are difficult to continuously collect.
The calculus stacking is that different materials are respectively added into two or more extruders for melting and plasticizing, the melt is compounded into double-layer or multi-layer melt in a confluence device, the double-layer or multi-layer melt is divided into multiple strands by a laminator, and the multiple strands are twisted, widened and converged to complete one-time stacking. Through a plurality of cascade devices connected in series, the polymer melt is repeatedly laminated to obtain the alternating multilayer composite material, and the thickness of each layer can reach the nanometer level. In the repeated lamination process of polymer melt, the thickness of the polymer layer is continuously thinned under the continuous action of drag flow and shear flow, but the calculus lamination requires a stable runner to maintain the lamination state, so the polymer melt is mainly used for the extrusion preparation of composite material sheets or films and is rarely applied to melt processing of centrifugal spinning.
Chinese patent CN103590122B proposes the design of a calculus laminator with flat inlet and round outlet and the application of a gas-assisted internal conical nozzle, which combines laminator and melt electrospinning, and simultaneously melt-spins two incompatible polymers. The advantage of this method is that the fibers are very thin, but electrospinning is inefficient and requires a complex electric field environment.
