Bicomponent electrospinning

Bicomponent electrospinning. Bicomponent fibers or bicomponent fibers (Alm. bicomponent fiber, French bicomponent fiber, Eng. bicomponent fiber) are fibers that consist of two different polymer structures. bicomponent fibers; Referred to as bicomponent fiber or bicomponent fiber, bicomponent fiber is made up of two different fibers that take advantage of the desirable properties of both materials. Such fibers can be formed by spin extrusion. One or both fibers can remain in the final product, or the first fiber can dissolve leaving only the other fiber in the final product.

Production of bicomponent fibers is one of the methods of producing synthetic fibers, which is based on the extrusion of two different polymers. With this method fibers can be given different properties. Depending on the end use, it is possible to produce special fibers by selecting the fiber part. Bicomponent fibers are also of commercial interest in this area.

Bicomponent fibers are designed to meet the needs of two materials in one fiber throughout the length of the fiber. Therefore, they are also referred to as composite, conjugate and hetero fibers. In contrast to polymer blends, they consist of two different polymers that are clearly separated from each other along the fiber length, which offers a great advantage in addition to the properties of the polymers themselves. The purpose of producing bicomponent fibers is to improve the performance of materials depending on the area of ​​application. The performance of bicomponent fibers depends on the performance of each of the fiber components, the compositional ratio, and the interaction between the components.

Thanks to the two-component fiber technology, it is possible to produce optional special fibers by selecting the appropriate section, depending on the end application. Viscosity, cooling rate, and surface tension of two polymer components are essential to the formation and properties of bicomponent fibers. The viscosity of each component must be similar to get the desired fiber content. cooling speed; Surface tension while determining the orientation of each component. The adhesion of the two components and the final surface determine the cross-sectional area of ​​the fibers. Bicomponent yarn is also known as bicomponent, bicomponent, or two-component yarn, which is made from two types of yarn.

Bicomponent fiber

Synthetic fibers play an important role in people’s lives today. Synthetic fibers and textile surfaces composed of them are used in many applications in the technical textile industry, such as airbags, cable fabrics, filters, composite materials, conveyor belts, optical materials, thermal and acoustic insulation materials and textile products. Traditional. . . The production of bicomponent fibers is one of the methods for the production of synthetic fibers, which is based on the drawing of two different polymers towards each other. With this method fibers can be given different properties. Depending on the end use, specific fibers can be made by choosing the cross-section of the fibers. Bicomponent fibers are also of commercial interest. In this article; The history of bicomponent fibers, definition of bicomponent fibers, manufacturing processes and market status of bicomponent fibers are summarized, and commercial bicomponent fibers and particularly recent literature studies are included.

bicomponent fiber manufacturer

Side-by-side bicomponent viscose fibers were patented in 1937. The first commercial bicomponent fibers “Cantrese” were manufactured by Dupont in the 1960s. These fibers, intended for underwear, consist of the drawing of two different polyamide polymers alongside bicomponent fibers. Manufacturing Process It was introduced for use in non-woven fabrics and socks. In the 1970s, production of many types of bicomponent fibers began in Asia, particularly Japan. Very complex and expensive production facilities are used. In the 1970s, Monsanto Corporation produced Monol, a self-folding monofilament polyamide fiber.

After 1989, a different arrangement was used in an unconventional way, with a flat plate perforated with holes and channels to guide the polymer. This method was widely accepted and started to be used as a very useful and profitable method. In 1984, 13 different manufacturers of bicomponent acrylic fibers were producing side by side around the world. Between 1988 and 1991, bicomponent fibers experienced rapid growth. In 1992, Morgan published 15 companies that manufactured both domestic and foreign components.

natural bicomponent fiber

The production of bicomponent fibers means the combination of two different chemical and/or physical polymers in a single fiber. Bicomponent fibers are designed to meet the needs of two materials in one fiber throughout the length of the fiber. Therefore, they are also referred to as “composite”, “conjugate” and “hetero” fibers. In contrast to polymer blends, they consist of two polymers that are clearly separated from each other along the fiber length, which offers a great advantage in addition to the properties of the polymers themselves. The purpose of producing bicomponent fibers is to improve the performance of materials depending on the area of ​​application.

what is a bicomponent fiber

The performance of bicomponent fibers depends on the performance of each of the fiber components, the compositional ratio, and the interaction between the components. By using the two-component technology, specific fibers can be manufactured depending on the end use by selecting the appropriate part. Viscosity, cooling rate, and surface tension of two polymer components are essential to the formation and properties of bicomponent fibers.
