Shrinkage rate is the main quality indicator for measuring high shrinkage products- Under normal circumstances. A high shrinkage bladder fiber with a shrinkage rate between 20% and 25% can be used to produce jacquard fabrics, knotted fabrics, etc.; a shrinkage rate between 25% and 30% can be used to produce blankets, carpets, and fur suitable for people; a shrinkage rate above 30% is an ultra-high shrinkage bladder fiber.

Faced with the increasingly severe refined fiber market, Daqing Petrochemical Company's Bran Fiber Factory evaluates the development trend of the international Bran fiber market and the development trend of new products. Dedicated to developing high value-added products that are suitable for market demand and increasing technological content. Forming core technological advantages. After in-depth research. It is learned that ultra-high shrinkage nylon fibers have broad prospects. At that time, Chinese nylon enterprises did not have the ability to produce
In August 2020, the factory established a project team for ultra-high shrinkage nylon fibers and designed many technical solutions with the aim of achieving a shrinkage rate of over 30%. After continuous exploration, the parameters and process reengineering of various processes such as raw material preparation, polymerization kettle reaction, spinning have all been broken. The ultra-high shrinkage acrylic fiber produced has a shrinkage rate of over 40%.
Currently. The factory is currently experimenting with other ultra-high shrinkage products to meet different market demands.
