The traditional garment materials are generally produced by adopting raw materials such as pure cotton, cellulose fiber, terylene and the like, and although the garment adopting the pure cotton, viscose or other cellulose fiber absorbs sweat, the garment also has the problem of moisture storage and flowing, the garment can be heavy when being worn because a human body sweats and is stuck on the skin, so that the relative humidity in a microenvironment is increased, and the garment is dry for a long time, so that the garment is uncomfortable to wear.

The coffee carbon fiber is a functional fiber produced by calcining coffee residues left after coffee is drunk to prepare crystals, grinding the crystals into nano powder and adding the nano powder into polyester fiber, and has the functions and characteristics of bacteriostasis, deodorization, negative ion emission, ultraviolet resistance, heat storage, heat preservation, low carbon and environmental protection. However, the coffee carbon fibers generally have good air permeability after being blended with fibers having excellent air permeability, such as cotton fibers and hemp fibers, in general. For example, chinese patent CN2012101036675 discloses a Jutecell coffee carbon fiber knitted fabric and a preparation method thereof, wherein a natural cotton fiber, Jutecell fiber and coffee carbon fiber are blended to obtain a knitted fabric with good skin-friendly property, antibacterial and mildewproof properties, moisture absorption and quick drying, and good air permeability and heat preservation. The technology utilizes the Jutecell fibers to have good skin-friendly property, bacteriostasis, mildew resistance, moisture absorption, quick drying, good air permeability and heat preservation, utilizes the coffee carbon fibers to have excellent peculiar smell eliminating function, and realizes the excellent performance of the knitted fabric through blending.
