Description
Gel-dying is a good method for production of colored fibers. Their major advantage is that they are color-fast and the end product is more uniformly dyed in textile industries. The color-fastness against such natural elements as sunlight, washing, etc is unparalleled among manmade fibers. Depending on the customer’s demand, the fibers are produced with a variety of detexes.
Our acrylic fibers are produced using monomer acrylonitrile as the major monomer (over 85%), methylacrylate or vinyl acetate as the second comonomer (less than 15%) and a third comonomer for dyability, by Solution Polymerization and Wet Spinning using SNIA technology. In both dull and semi-dull product, Titanium Dioxide (max 0.5%) is used. Also, in the process of production, the fibers are submerged in finish (finish of about 0.5%) prior to packing. The following are some of the major characteristics of our products:

Production Process and Packaging
Consistent with SNIA technology, the production process for this product starting with the mixing of monomers as feedback input to the reactors for polymer solution in Dimethylformamide (DMF) in the Chemical Area through to fiber production, drawing, finishing and packaging is continuous and that at each stage samplings and controls are conducted and finally the product is graded and released in accordance with the test results. Bright, dull and semi-dull products are normal. The product is packaged in bales weighing 350±۲۰ kg and then put in covered polypropylene jute and rod guards. The bales measure 120*110*73 mm. 20-22 tons of the product can be transported in a 40-foot container.
