Abstract

The invention provides an intelligent heat-moisture driven core-spun yarn and a moisture-absorbing and quick-drying fabric, wherein the moisture-absorbing and quick-drying fabric is knitted from the core-spun yarn. The core yarn of the core-spun yarn is a synthetic fiber filament, and the outer fiber is a heat-humidity responsive fiber, which is a parallel composite fiber with a peanut-shaped cross-section composed of a hydrophilic antibacterial fiber and a hydrophobic light-to-heat conversion fiber, and the The diameter ratio of the hydrophilic antibacterial fiber and the hydrophobic light-to-heat conversion fiber is 2.5:1-1:2.5. The water absorption rate of the moisture-absorbing and quick-drying fabric provided by the invention is more than or equal to 350%, the evaporation rate is more than or equal to 0.3g / h, and the moisture permeability is more than or equal to 450g / (m 2 h), using the difference in the amount of deformation produced by the hydrophilic antibacterial fiber and the hydrophobic light-to-heat conversion fiber in the outsourcing fiber to light-heat stimulation and humidity stimulation, to produce bending deformation movements in different directions, thereby tightly wrapping the core yarn, increasing the Through the gaps between the yarns, the moisture and heat of the fabric are quickly discharged, so as to realize the function of moisture absorption and quick drying.

Description

technical field [0001] The invention belongs to the technical field of textile materials, and in particular relates to an intelligent heat-moisture-driven core-spun yarn and a moisture-absorbing and quick-drying fabric. Background technique [0002] With the continuous improvement of people's living standards, people have higher and higher requirements for the comfort, health, safety and environmental protection of clothing fabrics. In the future, clothing fabrics will develop in the direction of comfort, health and intelligence. Sweat and related functional textiles will become a major trend in future market consumption. [0003] As we all know, natural fibers take cotton as an example, which has good hygroscopicity and is comfortable to wear. However, when a person sweats a little, the cotton fiber will expand due to moisture absorption, and its air permeability will decrease and stick to the skin. It is also slower, thus causing a cold and wet feeling to the human body; ...
