Modular electrostatic spinning device

Abstract

The invention discloses a modular electrostatic spinning device which comprises a discharging device, a collecting device and a modular spinning assembly arranged between the discharging device and the collecting device. The modular spinning assembly is composed of at least two spinning modules which are sequentially and evenly arranged in the advancing direction of the core yarn. Each spinning module comprises two propelling devices and a metal rotating funnel; the two propelling devices are located on the same horizontal plane. The metal rotating funnel has the same distance with the two propelling devices, is positioned on the middle vertical plane of the two propelling devices, and is positioned in the range of an electrostatic field generated by the propelling devices when high voltage is introduced; one of the two propulsion devices is connected with the positive electrode of the power supply, and the other is connected with the negative electrode of the power supply for generating an electrostatic field. Modular design is adopted, the performance of the composite yarn can be controlled, compounding of multiple materials is achieved, and the nano composite yarn of the multi-gradient skin-core structure is prepared.

Description

technical field [0001] The invention relates to the field of electrospinning, in particular to a modular electrospinning device. Background technique [0002] Due to its quantum size effect and macroscopic quantum tunneling effect, nanofibers can bring many unique properties to materials. If nanofibers or nanofiber bundles are combined with traditional textiles and introduced into the textile industry, it can improve the performance of the textile industry. The status quo, processing functional products with high added value. [0003] So far, most electrospun nanofibers have been collected in the form of non-woven fabrics. The collected nanofibers are randomly arranged, have low mechanical properties, and cannot be woven, which greatly limits their application fields. .

[0003] So far, most of the electrospun nanofibers are collected in the form of non-woven fabrics, the collected nanofibers are arranged randomly, have low mechanical properties, and cannot be woven, which greatly limits its application fields.

In the document "S.H.Ji, Y.S.Cho, and J.S.Yun. Wearable Core-Shell Piezoelectric Nanofiber Yarns for Body Movement Energy Harvesting [J]. Nanomaterials (Basel), 2019, 9 (4): 555-563." The nanofiber membrane is cut into strips with a relatively large length and diameter, and then wound on a conductive wire to make a core-sheath nanofiber yarn, so that it can be woven and sewn on the fabric, thereby increasing its application field, but This method will have a certain impact on the fiber strength during the cutting process, which will reduce the mechanical properties of the strip fiber membrane, and the twisting parameters of nanofibers are not easy to control, and the production efficiency is not high.

Poling-freespinning process of manufacturing piezoelectric yarns for textile applications[J].Materials&Design,2019,179:107889-107898." In the process of stretching and twisting, the fiber yarn is produced by spinning first and then twisting and pulling. However, the fiber yarn produced by this method has a single function, the mechanical properties of pure nanofibers are poor, and the effect is not ideal. App is restricted
