摘要：
Provided is a process for forming a dissolvable fiber, the process including (a) producing an extrudate from a twin screw extruder and (b) forming the extrudate into the dissolvable fiber. The dissolvable fiber includes (i) from about 10% to about 60% of one or more anionic surfactants (ii) from about 10% to about 50% of one or more water soluble polymers (iii) from about 1% to about 30% of one or more plasticizers and (iv) from about 0.01% to about 30% water. The one or more anionic surfactants have a Krafft point of less than about 30° C. The dissolvable fiber has an average diameter of from about 20 microns to about 1,000 microns.
