HYDROPHOBIC CELLULOSIC FIBER

The present disclosure relates to a continuous process for preparing hydrophobic regenerated cellulosic fiber. Said process comprises treating never-dried cellulosic fiber with a hydrophobic composition comprising 0.05 - 2.5 weight % of an alkyl ketene dimer based on weight of cellulose. The alkyl k...

Summary:The present disclosure relates to a continuous process for preparing hydrophobic regenerated cellulosic fiber. Said process comprises treating never-dried cellulosic fiber with a hydrophobic composition comprising 0.05 - 2.5 weight % of an alkyl ketene dimer based on weight of cellulose. The alkyl ketene dimer has a formula I: wherein both R
