Benefits of technology

The invention describes a fiber blend that includes hydrophobic fibers with multiple lengths and deniers. The blend can be used to make yarns, fabrics, garments, and linens that have improved properties for managing moisture. These properties include faster water release rates, wicking, and drying times.

Problems solved by technology

These fabrics, however, do not have the appearance, ability to wick quickly, or comfortable feel of untreated cellulosic fabrics.
In addition, these fabrics are typically treated with a hydrophobic chemical, or are blended with a synthetic fiber or hydrophobic treated yarn that does not absorb water, which reduces the overall ability of the fabric to absorb water compared to an untreated fabric.
Thus, these fabrics do not sufficiently absorb water and are not well suited for drying applications, such as towels, for example.

[0156]A fabric knitted from Yarn A (invention) (Fabric A) (invention) and a fabric knitted from Yarn B (Fabric B) (comparative) were dyed and finished in the same manner. These fabrics were evaluated for their hand / softness and drying time performance as detailed below:

Hand / Softness Evaluation

[0157]The hand of the fabrics was evaluated in accordance with American Association of Textile Chemists and Colorists (AATCC) Evaluation Procedure 5 (2011) (Guidelines for the Subjective Evaluation of Fabric Hand). Seven out of ten evaluators rated Fabric A (invention) to be softer than Fabric B (comparative). Of the remaining three evaluators, only one rated Fabric B (comparative) to be softer than Fabric A (invention), while the other two rated Fabric A (invention) and Fabri...

Abstract

Fiber blends having hydrophobic fibers of both multiple staple lengths and multiple deniers of a single composition are disclosed. Yarns, fabrics, garments, and linens comprising the fiber blends with improved moisture management properties are also disclosed. Fabrics formed from the fiber blends have a water release rate at least about 10% greater than a comparative fabric that is compositionally identical but whose hydrophobic fibers are not both of multiple staple lengths and multiple deniers.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Application No. 61 / 914,080 filed Dec. 10, 2013, the entire disclosure of which is incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention generally relates to fiber blends and yarns and fabrics produced therefrom. More particularly, the invention relates to fiber blends and yarns and fabrics produced therefrom, which have improved moisture management (water release rate, wicking, and drying time) properties.BACKGROUND OF THE INVENTION[0003]Fast drying fabrics comprising cellulosic yarns provide garment benefits in the areas of active sports, outdoor work, recreational activities, military and other uses for example, where the rate of perspiration is high. In some cases, fabric is treated with a water resistant chemical to a degree that the entire fabric becomes water resistant or hydrophobic. In other cases, a blend of cellulosic and synthetic yarns is incorporated int...
