1. Dilemma of traditional spinning technology
For a long time, traditional spinning technology has dominated the textile field and made great contributions to fiber production. However, with the continuous increase in market requirements for fiber performance, especially in the face of products such as Colored High Elastic Yarn that have strict requirements for elasticity and diversified properties, traditional spinning technology has gradually shown signs of fatigue. Complex elasticity requirements mean that the fiber must not only have excellent tensile properties, but also be able to quickly and accurately restore to its original state after multiple stretching, which places extremely high demands on the stability of the fiber's internal structure. At the same time, the diverse fiber property requirements, such as color fastness, hand texture, etc., make it difficult for traditional spinning technology to take into account. In the traditional spinning process, due to the limited control accuracy of key parameters such as temperature, pressure, and flow rate, the internal structure is prone to unevenness during fiber molding. This unevenness causes the fiber to show large differences in properties such as strength and elasticity, which cannot meet the production needs of high-end textile products. For example, when making high-end sportswear, clothing made of fibers produced by traditional spinning technology may be damaged during wearing due to insufficient local fiber strength, or the wearing comfort may be affected due to inconsistent elasticity, which greatly limits the improvement of product quality and the expansion of application areas.
2. The birth of new spinning technology
Faced with the difficulties of traditional spinning technology, a technological revolution aimed at breaking through bottlenecks has quietly begun. For the production of colored high-elastic yarn, a new spinning technology came into being. This innovative technology brings together the wisdom and efforts of many scientific researchers and integrates multidisciplinary knowledge such as cutting-edge materials science and precision engineering technology. It redefines the fiber forming process with a new concept and method, bringing unprecedented possibilities for improving fiber quality.
3. Precise parameter control, laying the foundation for quality
A core advantage of the new spinning technology lies in the precise control of every parameter in the fiber forming process. From subtle temperature adjustment to precise pressure setting, to stable flow rate control, each link is given extremely high precision requirements. In the critical stage of fiber forming, precise temperature control is particularly important. The appropriate temperature can ensure that the polymer raw materials are in the best molten state, so that their molecular chains can stretch freely and arrange in order. If the temperature is too high, the polymer may degrade, affecting the strength and performance of the fiber; if the temperature is too low, the raw materials cannot be fully melted, resulting in difficulty in fiber molding and unstable quality. The new spinning technology uses an advanced temperature control system to control temperature fluctuations within a very small range, providing a stable and suitable thermal environment for fiber molding.
Pressure control is also indispensable. During the spinning process, pressure determines the speed and uniformity of spinning solution extrusion. The new spinning technology uses high-precision pressure sensors and intelligent control systems to monitor and adjust pressure in real time to ensure that the spinning solution is extruded at a constant and uniform speed. In this way, the fiber can obtain consistent density and structure during the formation process, avoiding problems such as uneven fiber thickness caused by pressure fluctuations.
Flow rate control further optimizes the fiber molding process. By precisely controlling the flow rate of the spinning solution, the new spinning technology can achieve precise control of the fiber diameter to meet the diverse requirements of different products for fiber specifications. Whether it is fine denier fiber for thin and breathable fabrics or coarse denier fiber for high-strength industrial products, it can be produced with high quality through precise flow rate control. This all-round and precise control of parameters such as temperature, pressure, and flow rate lays a solid foundation for improving fiber quality, so that each fiber has the potential for excellent performance from the beginning.
4. Unique nozzle design and extrusion method to optimize internal structure
In addition to precise parameter control, the new spinning technology has also made bold innovations in nozzle design and spinning liquid extrusion method. The special nozzle design is another key factor in improving fiber quality. When traditional nozzles are forming fibers, it is often difficult to ensure uniform distribution of spinning liquid, which easily leads to defects in the internal structure of the fiber. The new nozzle adopts a unique geometric shape and internal flow channel design, which can make the spinning liquid evenly dispersed during the extrusion process to form a stable and consistent thin stream. For example, some new nozzles use a multi-channel design to divide the spinning liquid into multiple small streams, which quickly merge after spraying out of the nozzle to form a fiber with uniform structure. This design effectively avoids the turbulence and aggregation of the spinning solution inside the nozzle, greatly improving the uniformity of the internal structure of the fiber.
At the same time, the new spinning technology also optimizes the extrusion method of the spinning solution. Abandoning the traditional simple extrusion method, a more complex and sophisticated extrusion process is adopted. During the extrusion process, by applying specific shear force and tensile force to the spinning solution, the polymer molecular chains are guided to be oriented inside the fiber. This directional arrangement makes the internal structure of the fiber more orderly and enhances the strength and elasticity of the fiber. Imagine that the polymer molecular chains are like closely arranged steel bars, forming a solid support structure inside the fiber, so that the fiber can better disperse stress when subjected to external force and is not easy to break. This unique nozzle design and extrusion method enables the fiber to have a uniform and stable internal structure at the moment of formation, providing a solid guarantee for its subsequent excellent performance.
