In this work, a preparation method of three-component composite fibers with complex cross-sectional patterns is proposed, and the fibers with complex cross-sectional patterns are fabricated using melt spinning. Initially, inspired by the shape of a fishbone, a spinning pack with three-component melt channels is designed for spinning fibers with a fishbone cross-sectional pattern. Then, the numerical simulation of the melt flow in the channels of the spinning pack is performed using Polyflow software. The spinning pack structure is optimized by analyzing the flow velocity distribution and shear rate distribution of different components within the spinning pack channels. The results show that smaller velocity fluctuations contribute to the clarity of the cross-sectional pattern. Thereafter, the spinning experiments are carried out based on the optimized spinning pack. The effect of the flow ratio between the three components on the cross-sectional pattern is discussed, and the three-component composite fibers with a clear fishbone cross-sectional pattern is obtained. Finally, in order to further study the effectiveness of the complex cross-sectional pattern fiber preparation proposed in this paper, another spinning pack for fibers with an H-shaped cross-sectional pattern is designed according to the aforementioned method, and spinning experiments are carried out. The SEM images of the cross-sections of fibers with fishbone and H-shaped cross-sectional patterns are obtained, verifying the feasibility of the method proposed in this paper. Moreover, the fibers with complex cross-sectional patterns obtained by this method have a certain anti-counterfeiting effect and can also be blended with other yarns to obtain fabrics with anti-counterfeiting effects.

In this work, a preparation method of three-component composite fibers with complex cross-sectional patterns was proposed, and the fibers with complex cross-sectional patterns were fabricated using melt spinning. Initially, inspired by the shape of a fishbone, a spinning pack with three-component melt channels was designed for spinning fibers with a “fishbone” cross-sectional pattern. Then, the numerical simulation of the melt flow in the channels of the spinning pack was performed using Polyflow software. The spinning pack structure was optimized by analyzing the flow velocity distribution and shear rate distribution of different components within the spinning pack channels. The results showed that smaller velocity fluctuations contribute to the clarity of the cross-sectional pattern. Thereafter, the spinning experiments were carried out based on the optimized spinning pack.

“…Bicomponent fibers or Bico fibers are typically synthetic. The American Society of Testing Materials (ASTM) recognizes a bicomponent fiber as a fiber composed of two polymers that are chemically or physically distinct (or both) [1]. 'Composite', 'conjugate' or 'hetro' fibers are often referred to as bicomponent fibers [2].…”

“…Several factors determine the cross-section of a bicomponent fiber: the polymer distribution/metering spin pack of the plate, the adjusting of the two polymer viscosities, and the interfacial tension between those polymers [1]. The quality and properties of the materials used, their arrangement in the fiber, their relative proportions and the obtained thickness of the fiber decide the characteristics of the bicomponent fibers [8].…”

Bi-component fibers are fibers that in a single fiber consist of two distinct raw material components. It is made by simultaneously spinning two compositions in each capillary of the spinneret. Core-sheath (C/S), side-by-side (S/S), segmented-pie (orange) and islands in-the-sea (I/S) are the most common types of bico fibers. The growing demand for non-woven fabrics is one of the growth drivers of the global bi-component fiber industry. In addition, bico fibers are also used in the manufacture of bulky goods, microfiber fabrics, advanced textiles, etc. Various types of commercial bico fibers as well as bico fiber fabrics are manufactured by many companies around the world. However, different aspects of bico fibers, their suitability in various fields of application, and some commercially available bico fibers are briefly reviewed in this paper.
