Abstract
A stitchbonded comfort fabric is disclosed that is absorbent, durable and quick-drying. The fabric is made up of an absorbent, evaporation-reservoir layer and a nonabsorbent, transport layer. The evaporation-reservoir layer comprises a nonwoven web that is stitched with at least one bulkable stitching yarn. The transport layer weighs at least 10 gms/sq m and can be formed from a network of fibrous stitching yarns that do not significantly absorb water and do not exhibit stitching gaps wider than 3 mm. The resulting fabric has a basis weight of between 20 and 120 gm/sq. m, a bulk of at least 10 cc/gm and the capability of absorbing at least 5 times its weight in water. The fabric is useful in intimate apparel, underwear, swimwear, sports shirting, headbands and comfort linings.
Claims15
A durable, nonwoven comfort fabric having a basis weight of from 20 to 120 grams per square meter, the fabric comprising:
- (a) an absorbent, evaporation-reservoir layer formed from a nonwoven web that is stitched through with at least one bulkable stitching yarn that forms spaced-apart rows of stitches extending along the length of the web;
- and
- (b) a nonabsorbent, transport layer weighing at least 10 grams per square meter and formed from a network of stitching yarns which are not significantly water absorbent and which are stitched through the web, the network exhibiting stitching gaps no wider than 3 millimeters,
- wherein the resulting dual-layered, stitchbonded fabric has a bulk of at least 10 cubic centimeters per gram and is capable of absorbing at least 5 times its weight in water.
A durable, nonwoven comfort fabric comprising:
- (a) an absorbent, evaporation-reservoir layer formed from an absorbent, nonwoven web;
- and
- (b) a nonabsorbent, transport layer weighing at least 10 grams per square meter and formed from a nonwoven, fibrous web which does not significantly absorb water,
- wherein the webs are stitched together with at least one bulkable stitching yarn that forms spaced-apart rows of stitches extending along the length of the absorbent, nonwoven web to form a dual-layered fabric having a bulk of at least 10 cubic centimeters per gram and capable of absorbing at least 5 times its weight in water.
