In recent years, with the continuous improvement of living standards, consumers have higher and higher requirements for the visual, tactile sense, and comfort of clothing. The demand for fine-denier acrylic fibers in the apparel market is steadily expanding. Fine-denier acrylic fibers have become domestic The important direction of the differential development of acrylic enterprises. Compared with conventional acrylic fiber, fine denier fiber technology is complex, difficult to produce, and has high value-added products. At present, the price of similar fine denier acrylic fibers on the market is about 1,000 yuan/ton higher than that of conventional acrylic fibers. Anqing Petrochemical targeted this highly promising market and began to explore the fine-denier fiber forming process in cooperation with Donghua University in November 2010: to determine the spinning process of fine-denier acrylic fibers, including negative elongation, draft multiples, Solidification conditions, washing and densification conditions, etc.; research and design of spinnerettes for fine-denier acrylic fibre spinning, increasing the density of holes, designing a reasonable distribution of holes, reducing excessive pressure in the frame and blocking the holes in the spinneret holes Improve on-line drafting equipment, so that the device has a large-scale production capacity. After nearly 10 months of joint development, on the basis of the small-scale denier acrylic fiber test, using the existing liquid preparation system, a new precision filter material was used on the secondary filter and the spinning candle filter corresponding to the spinning production line. The fine filtration of the raw liquid, and the application of a newly developed special spinneret for small-lot trial production on the spinning line, in mid-August last year, successfully produced 45 tons of 0.8 denier fine acrylic fiber. The fine denier acrylic fiber is spun into 40, 60 yarns, smooth, soft, delicate and soft to the touch. At the same time, it has the fine characteristics of fine fabric, light weight, smoothness, good drapability and anti-pilling, etc. Fastness up to level 4 and anti-pilling up to level 4 can be used as the main raw material for imitation cashmere and silk imitation. Can replace cashmere, can be blended with wool, blended with natural fibers, used in high-end apparel fabrics. The expert group of the company group highly affirmed the research results of the project and believed that the performance of the fine-denier acrylic fiber products meets or exceeds the targets of the project task book, and the project development improves the differentiation rate and enhances the product market competitiveness.
