Process of Forming a Dissolvable Fiber

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.

1. A process for forming a dissolvable fiber comprising:
a. producing an extrudate from a twin screw extruder; and b. forming the extrudate into the dissolvable fiber, the dissolvable fiber comprising:
i. from about 10% to about 60% of one or more anionic surfactants, by weight of the dissolvable fiber, wherein the one or more anionic surfactants have a Krafft point of less than about 30° C.;ii. from about 10% to about 50% of one or more water soluble polymers, by weight of the dissolvable fiber;iii. from about 1% to about 30% of one or more plasticizers, by weight of the dissolvable fiber; andiv. from about 0.01% to about 30% water, by weight of the dissolvable fiber; wherein the dissolvable fiber has an average diameter of from about 20 microns to about 1,000 microns.
