Abstract
Rotary spinning processes, more particularly processes for making hydroxyl polymer-containing fibers using a rotary spinning die, hydroxyl polymer-containing fibers made by the processes and webs made with the hydroxyl polymer-containing fibers are provided.
Claims22
A process for making one or more hydroxyl polymer-containing fibers, the process comprising the steps of:
- a. providing a hydroxyl polymer-containing composition comprising an uncrosslinked starch and/or starch derivative and a crosslinking system wherein the hydroxyl polymer-containing composition is free of unmodified, unsubstituted cellulose;
- b. supplying a rotary spinning die with the hydroxyl polymer-containing composition;
- and
- c. operating the rotary spinning die such that the hydroxyl polymer-containing composition exits the rotary spinning die as one or more hydroxyl polymer-containing fibers.
A process for making one or more hydroxyl polymer-containing fibers, the process comprising the step of subjecting providing a hydroxyl polymer-containing composition comprising an uncrosslinked starch and/or starch derivative and a crosslinking system to a rotary spinning process such that one or more hydroxyl polymer-containing fibers are produced wherein the hydroxyl polymer-containing composition is free of unmodified, unsubstituted cellulose.
A process for making one or more hydroxyl polymer-containing fibers, the process comprising the steps of:
- a. providing a first composition comprising a first material;
- b. providing a second composition comprising a second material;
- c. supplying a rotary spinning die with the first and second compositions;
- and
- d. operating the rotary spinning die such that the first and second compositions exit the rotary spinning die as one or more multi-component fibers;
- wherein at least one of the first material and second material comprises a hydroxyl polymer-containing composition comprising an uncrosslinked starch and/or starch derivative and a crosslinking system wherein the hydroxyl polymer-containing composition is free of unmodified, unsubstituted cellulose.
