The fabric with the differential moisture permeability has different moisture permeability on the front surface and the bottom surface so that liquid water (sweat) can be more conveniently transferred from the side with the weak moisture permeability to the side with the strong moisture permeability during the actual use process of the fabric. During normal wearing, sweat can be discharged away from the skin particularly during sports sweating, so that better dry and comfortable feeling can be felt. If the moisture-conducting capacity of the cloth bottom is higher than that of the cloth surface, the effects of water locking and moisture retention can be achieved for some special conditions, such as dry skin in winter.
The fabric differential wet permeability has been tested by the standards AATCC 195 "Liquid Moisture management properties of Textile Fabrics" and GB/T21655.2 "evaluation of quick Moisture absorption drying of textiles section 2: dynamic moisture transfer method "performance measurements were performed. The one-way transmission index is used to describe the differential wet permeability, and generally a one-way transmission index (O) higher than class 3 or greater than 100 is considered to have a significant differential water conductivity (GB/T21655.2).
The technical implementation scheme of the existing differential moisture-conducting fabric can be classified into two major categories, wherein the first major category is that the surface of the existing fabric is treated through different after-finishing processes, so that the differential water guiding of two sides of the fabric is realized. However, in the method, the washing fastness of the auxiliary agent is not high, the function is generally reduced or even eliminated after a certain number of times of washing, and the material characteristics and the texture structure of the treated fabric influence the treatment effect. The second category is that hydrophobic yarns and hydrophilic yarns are utilized to achieve the function through the design of the hydrophilic and hydrophobic yarns at different positions on two sides of the fabric on the weave structure of the fabric, but the prior art does not discuss that the structure of the yarns can also obviously influence the hydrophilicity and the hydrophobicity and the water conductivity of the yarns, so that the differential moisture conductivity of the fabric is influenced. With the wide application of seamless knitting technology, people pay more and more attention to the realization of certain functions on equipment and process for seamless weaving, so that people can feel the seamless smoothness and fit of the top-coat and can also feel the functional benefit of the fabric serving as the second layer of skin on heat and moisture transfer when wearing the seamless fabric.

Liquid water such as sweat and the like is conveniently transferred in the yarn in the horizontal direction, and meanwhile, the liquid water is transferred in the vertical direction. When the liquid water is transferred in the vertical direction, the additional pressure of the capillary in the yarn is mainly used for overcoming the action of the gravity field of the liquid water, so that the climbing or lowering height of the liquid water in the capillary can be calculated according to the characteristics of the capillary; when the capillary is in a horizontal position, although the potential energy difference of an external force field does not exist, the liquid can be automatically guided to flow due to the additional pressure action of the capillary, and the flow rate of the capillary can be calculated according to the following formula:
in the formula
q capillary flow (m)3/s)；
η liquid viscosity (Pa.s);
l capillary length (m)
The formula (1) shows that the liquid flow in the capillary is related to the contact angle between solid and liquid, and the stronger the hydrophilic and hydrophobic performance is, the stronger the conveying capacity of the capillary is. The larger the capillary equivalent radius, the greater the transport capacity.
