Abstract
An alginate-based fiber is made of a composition comprising an alginate, a cellulose and a polyol plasticizer, such as glycerol. The fiber is produced through extrusion in a curing bath containing calcium. The fiber provides excellent strength and flexibility in its unhydrated state for textile applications. The fiber can be used to produce textiles as compostable alternatives to petrochemical based polymers.
Claims12
A fabric, comprising:
- a fiber,
- wherein the fiber is contained within a yarn, a knit, or a woven textile,
- wherein the fiber is produced through extrusion,
- wherein the fiber is produced by curing an alginate composition in a curing bath, and
- wherein the alginate composition has a total mass and comprises (i) methyl cellulose, (ii) a polyol plasticizer that is a glycerol, (iii) an amount of sodium alginate that ranges from about 3.75 wt % to about 7.85 wt % of the alginate composition's total mass, (iv) an amount of methyl cellulose that is about 50 wt % to about 90 wt % of the amount of sodium alginate, and (v) an amount of glycerol that ranges from about 25 wt % to about 250 wt % of a total amount of sodium alginate and methyl cellulose in the alginate composition.
