PET Yarn in production management than ordinary white yarn requirements are much higher
Related statistics show that at present, China's overall production of PET Yarn yarn only about 5% of the total output. According to the national spinning production capacity of more than 100 million in the size of the calculation, if the future yarn industry to form color spinning, yarn-dyed, stained one-third of the pattern, then, PET Yarn industry scale will be more than 20 million spindles, and now, China's PET Yarn has only a few million dollars. In other words, PET Yarn is a relatively broad space for development. But the current situation is that although there is room for development, profits are shrinking. In this regard, the relevant sources pointed out that although in recent years China's PET Yarn industry has made such as enterprises continue to grow, diversification of color spinning products and product quality is becoming more stable and other achievements, but its development is still a problem, especially PET Yarn technical requirements are relatively high, Enterprises can not blindly invest. In addition, the continuous development of new fiber, new technology of new products, in order to always maintain the high value-added color spinning products.
PET Yarn in the production management than ordinary white yarn requirements are much higher, million jobs are usually more than 30% to 50% of the yarn. PET Yarn industry is facing many processes, the production of small quantities, variety, frequent changes and other issues. The same workshop often involves different mix ratio, different colors of the multi-species PET Yarn production, a slight negligence, will lead to the production of flying, batch number mixed confusion, resulting in a large area of defective products, affecting PET Yarn production quality.
Due to the strength of cotton after dyeing will drop 10% to 20%, neps increased by about 10%, so PET Yarn dyeing cotton quality requirements are relatively high. In the face of complex color spinning processing, China's PET Yarn enterprise technology investment is insufficient, the vast majority of enterprises have not established R & D institutions, scattered fiber dyeing process stability control and optimization does not pay enough attention to the production process of adding colored fibers to spinnability The impact of the law is not clear, very little systematic study of multiple components PET Yarn optimal composition and process optimization, thus affecting product quality and reduce the market competitiveness of enterprises.
According to industry insiders, China is currently the main rotor spinning, jet spinning, jet vortex spinning production PET Yarn. Despite the advantages and prospects of these new spinning technology applications, it is necessary to explore the different spinning technology of the spinning performance, product process stability control and optimization and appropriate product applications, while actively exploring other new spinning technology (Such as low torque spinning technology, embedded composite spinning technology, etc.) in the field of color spinning applications, in order to further expand the PET Yarn species, improve product quality and reduce production costs.
The innovation of the color spinning process, the progress of the color spinning technology and the development of the new colored fiber make the development of the characteristic PET Yarn line more diversified and provide more possibilities for the innovation of the color spinning product. With the development of non-cotton fiber production and variety at home and abroad, its application in PET Yarn is increasing, but the proportion is still low. The raw cotton still accounts for more than 80% of the share in PET Yarn. With the increasing proportion of non-cotton fiber used in cotton textile enterprises, how to reduce the proportion of cotton in PET Yarn and increase the use of non-cotton fiber is an important subject of color spinning technology innovation. In this regard, the industry believes that the use of a variety of differentiated and functional fiber mixed spinning, the development of wool, silk, lin and other high-grade natural fiber multi-component blended yarn, the market for the development of high-end yarn Trend, should cause the textile enterprises attach great importance and close attention.
