Electrostatic spinning submicron fiber and sliver composite blended yarn preparation device and method

Abstract

The invention discloses an electrostatic spinning submicron fiber and sliver composite blended yarn preparation device and method. The preparation device comprises a drawing frame and an electrostaticspinning device, the electrostatic spinning device comprises needle-free electrostatic spinning spray heads located on the two sides of a sliver respectively and a receiving pole plate, and the needle-free electrostatic spinning spray heads are connected with a high voltage generator; a liquid storage bottle is communicated with the needle-free electrostatic spinning spray heads. The preparationmethod comprises the steps that a control valve and a liquid supply pump are opened, and a spinning solution in the liquid storage bottle flows into the needle-free electrostatic spinning spray heads;the drawing frame is started, the high voltage generator is connected with the needle-free electrostatic spinning spray heads, the high voltage generator is started, multiple jet flows are sprayed out from the needle-free electrostatic spinning spray heads, in the process that the jet flows fly to the receiving pole plate, solvent is volatilized, high polymer is stretched and cured, and submicronfibers are formed and deposited on the sliver. Accordingly, blending of electrostatic spinning submicron fibers and fibers for traditional textile can be achieved, and the functional characteristicsof the submicron fibers are applied to the traditional textile.

Description

technical field [0001] The present invention is a combination of electrospinning technology and drawing frame technology, especially the modification of the drawing frame so that the electrospinning equipment can be applied to the drawing frame, and specifically relates to a composite blended yarn of electrostatic spinning submicron fiber cotton sliver The preparation device and method belong to the technical field of electrostatic spinning. Background technique [0002] In recent years, with the continuous promotion of nanotechnology, the application of nanotechnology has penetrated into all aspects of our lives. With the maturity of submicron fiber manufacturing technology represented by electrospinning, submicron fiber technology has gradually been applied to high-performance Filtration, special functional fabrics and medical applications, but there are few studies on the application of electrospinning technology to traditional textiles to truly realize the combination of...

[0004] The patent application number 201610847425.5 published by the Chinese Patent Office on September 21, 2016, the title of the invention is "Nano-electrospinning and staple fiber ring spinning yarn forming method". A single-needle electrospinning device is set between the front roller and the front rubber roller to realize the mixing of submicron fibers and traditional textile fibers, but in the actual use process, it is found that this method has the following disadvantages: the nozzle sprays downward It is easy to cause the spinning liquid to drop on the yarn or the machine, which will affect the normal yarn formation. The output on the spinning frame is low, and the submicron fiber is finely wrapped on the traditional yarn, and the submicron fiber will fall off during the subsequent use.

The patent application number 201310586642.X published by the Chinese Patent Office on November 20, 2013, the title of the invention is "a preparation method of submicron fiber blended composite yarn". Spray it on the cotton web that is about to be slivered to realize the compounding of submicron fiber and cotton fiber, but in the actual use process, it is found that it is used on the carding machine because the fiber web on the carding machine is a lap joint between fibers, and the fiber web is relatively small. It is thin and easy to break, and the carding machine needs to be modified and the cost is high. It can be used on the drawing frame to realize the mixing of traditional fibers and sub-micron fibers, and because the sub-micron fibers are thinner, it is the traditional textile fibers that combine sub-micron fibers in the composite yarn. Fiber coating, so that the function of the composite yarn is maintained
