US 7,407,514 B2 · Processing techniques for preparing moisture management textiles

Abstract

An integrated processing technique for preparing moisture management textiles or fabrics wherein fibers are treated with compositions which impart a hydrophobic or hydrophilic property such that when incorporated into the fabrication of composite structured textiles or fabrics a hydrophobic inner surface and a hydrophilic outer surface are formed. The integrated processing technique for preparing moisture management textiles also includes finishing the textiles or fabrics to enhance the fabric's liquid water one way transfer properties. The advantage of this invention is the possibility to manufacture the pure cotton woven/knit fabrics with the good moisture management properties.

Dependent claims

A method of producing a moisture managing textile comprising the steps of:

altering an absorbency of strands of fibers, said altering including:
(a) improving the absorbency of the strands of fibers by exposing the strands of fibers at a liquor ratio of about 30:1 to an aqueous mixture of caustic soda 5% (owf), sodium metasilicate, nonahydrate 2.5% (owf), sodium sulfite 2.5% (owf), anionic detergent 2.0 to 3.0% (owf), said exposure being at about 80° C. to about 90° C. for a period of about 1 to about 2 hours;
and
(b) washing the strands of fibers with fresh water;
modifying the hydrophobicity of the strands of fibers;
assembling strands of fibers into a textile having a first side and a second side;
modifying the textile wetability;
and
increasing a differential between a hydrophobic property and a hydrophilic property present in the strands of fibers in the textile.

A method of producing moisture management textiles comprising:

treating fibers with conditioning formulations, said treating including:
preparing the conditioning formulation from, caustic soda 5% (owf), sodium metasilicate, nonahydrate 2.5% (owf), sodium sulfite 2.5% (owf), and anionic detergent 2.0 to 3.0% (owf);
a liquor ratio 30:1;
exposing the fiber at a liquor ratio of about 30:1 to the conditioning formulation by soaping at either about 80° C. for about 2 hours or about 99° C. for about 1 hour;
and
washing the fiber with fresh water to yield a treated fiber;
modifying the hydrophobic properties of the fibers;
incorporating the modified fibers into a composite structure;
desizing fibers of the composite structure if necessary;
and
applying a functional treatment formulation to the composite structure.
