Fabric with fluid absorption capabilities
A fabric with fluid absorption capabilities is provided. The fabric includes a first layer, a second layer, and a spacer yarn. The first layer includes a hydrophobic yarn, and the second layer includes a hydrophilic yarn and a reinforcement yarn plied together. The hydrophobic yarn, the hydrophilic yarn, and the reinforcement yarn form a plurality of valleys on an upper surface of the first layer. The spacer yarn is configured to connect the first layer and the second layer.
1 . A fabric comprising:
a first layer comprising a hydrophobic yarn;
a second layer distal to the first layer, and comprising a hydrophilic yarn and a reinforcement yarn, wherein the hydrophilic yarn and the reinforcement yarn are plied together, and wherein the hydrophobic yarn, the hydrophilic yarn, and the reinforcement yarn form a plurality of valleys on an upper surface of the first layer; and
a spacer yarn configured to connect the first layer and the second layer.
2 . The fabric according to claim 1 , further comprising an absorbent layer disposed between the first layer and the second layer.
3 . The fabric according to claim 1 , wherein the reinforcement yarn is an elastomeric yarn.
4 . The fabric according to claim 1 , wherein the reinforcement yarn is a shrinkage yarn.
5 . The fabric according to claim 1 , further comprising a plurality of loops, wherein a cross-sectional area of a valley of the plurality of valleys is at least equal to a cross-sectional area defined by one loop of the plurality of loops.
6 . The fabric according to claim 1 , wherein a material of yarn of the first layer comprises polyester, nylon, polypropylene, viscose, acrylic, cotton, wool, or a combination thereof.
7 . The fabric according to claim 1 , wherein a material of yarn of the second layer comprises polyester, nylon, polypropylene, viscose, acrylic, cotton, wool, or a combination thereof.
8 . The fabric according to claim 1 , wherein a material of the spacer yarn comprises polyester, nylon, polypropylene, viscose, acrylic, cotton, wool, or a combination thereof.
9 . The fabric according to claim 1 , wherein the spacer yarn is hydrophobic.
10 . The fabric according to claim 1 , wherein the spacer yarn is hydrophilic.
11 . The fabric according to claim 2 , wherein the absorbent layer comprises cotton, rayon, or a combination thereof.
12 . The fabric according to claim 1 , wherein a thickness (T) between the first layer and the second layer is in a range of about 1 mm to 12 mm.
13 . A method of making a fabric, the method comprising:
knitting a hydrophobic yarn to form a first layer;
knitting a hydrophilic yarn and a reinforcement yarn together to form a second layer;
connecting the first layer and the second layer using a spacer yarn; and
forming a plurality of valleys on an upper surface of the first layer, wherein the hydrophobic yarn, the hydrophilic yarn and the reinforcement yarn form the plurality of valleys.
14 . The method according to claim 13 , further comprising swapping a plurality of stitches between the first layer and the second layer at predefined locations to form the plurality of valleys.
15 . The method according to claim 14 , wherein the reinforcement yarn is an elastomeric yarn, and wherein the plurality of stitches between the hydrophobic yarn and the elastomeric yarn are swapped at the predefined locations.
16 . The method according to claim 13 , further comprising applying a stimulus on the reinforcement yarn to form the plurality of valleys.
17 . The method according to claim 13 , wherein the reinforcement yarn is a shrinkage yarn.
18 . The method according to claim 13 , further comprising reducing a loop length of the hydrophilic yarn with respect to a loop length of the hydrophobic yarn to form the plurality of valleys.
19 . The method according to claim 13 , further comprising inlaying an absorbent layer between the first layer and the second layer.
20 . The fabric according to claim 1 , wherein the plurality of valleys comprises one or more channels to channel away moisture.
