A few days ago, the new products of fully-extinguished acrylic staple fiber developed by Shanghai Petrochemical achieved mass production for the first time. The first batch of 35 tons and 3 denes of this product was approved by the market to replace the quality requirements of imported products, breaking the monopoly of domestic and imported products in Japan and Thailand. situation.
Acrylic fiber can be divided into glossy, semi-extinction and full extinction from the glossiness. Conventional acrylic fiber has strong gloss, and the acrylic fiber used in high-end fabrics such as clothing, home and so on often needs to add titanium dioxide in the production process for matting.
The titanium dioxide content of the fully matt acrylic fiber product developed by Shanghai Petrochemical has reached 6-10 times that of the domestic semi-dull product, which obviously alleviates the glittering glare of the fiber appearance, making the fabric exhibit a soft luster like natural wool. At the same time, the product The addition of high-quality fractional titanium dioxide further enhances the fiber density, effectively improving the drape and hiding of the fabric, and improving the grade of the fabric.
It is understood that in May last year, Shanghai Petrochemical Acrylic Fiber Production Department began the industrialization research of fully extinction acrylic fiber, which solved the system problem of uneven dispersion of raw liquid, increased filtration impurities and unstable spinning operation caused by the increase of titanium dioxide content. Mass production began in early June this year.
