Moisture absorption and sweat releasing chemical fiber fabric

The utility model discloses a moisture absorption and sweat releasing chemical fiber fabric, and relates to the technical field of fabrics. According to the technical scheme, the breathable fabric is characterized in that the breathable fabric comprises an inner layer and an outer layer which are fixedly connected with each other, a plurality of contact strips with the same length as the outer layer are fixedly connected to the side, close to the inner layer, of the outer layer, each contact strip is composed of a plurality of contact velvet, and first breathable sections corresponding to the contact strips are arranged on the inner layer; the side, close to the outer layer, of the inner layer is fixedly connected with a plurality of moisture dissipation blocks, each moisture dissipation block is composed of a plurality of moisture dissipation velvet, the outer layer is provided with second ventilation sections corresponding to the moisture dissipation blocks, and the sectional area of the first ventilation sections and the sectional area of the second ventilation sections are larger than those of the contact strips and the moisture dissipation blocks respectively. The moisture absorption effect is guaranteed through the contact strips and the moisture dissipation blocks, channels for external air to enter the fabric are increased due to the arrangement of the first breathable section and the second breathable section, and the moisture absorption and dissipation performance of the whole fabric is guaranteed through the characteristics of the viscose fibers and the bamboo charcoal fibers.
