In this embodiment, the area covered by the face yarn is S_B＝S_1Y1+3S_2y2X W; the covering area S of the yarn of the knitted fabric garment_F＝S_2y1+3S_2y2。

First yarn Y₁The equivalent radius of the 80D/144F polyester monofilament is as follows:

D_Y1＝2×3.80＝7.6(μm)

D_Y2＝2×5.70＝11.4(μm)

in summary, the covering area of the skin surface yarn in the unit circulation weave structure of the knitted fabric is

In this example the first yarn Y₁(80D/144F) contact Angle of 55 °, second yarn Y₂The contact angle of (30D/24F) was 63 °. The knitted fabric was measured according to the standard AATCC 195 "Liquid Moisture Management Properties of Textile Fabrics". The measured unidirectional moisture-conducting capacity owtc (one way transport capability) of the fabric body is 280%.

Comparative example 6:

the same yarn count and structure as in comparative example 1, first yarn Y₁And a second yarn Y₂The terylene (80D/144F) is adopted to interweave with each other to form the weft-knitted single-sided fabric, and the structure is the same as that of the embodiment 1. The contact angle of the yarn was 53 °. The unidirectional moisture transport capacity owtc (one way transport capacity) of this fabric was measured to be 80%.

According to the comparison of the test results, the utility model enables the fabric to be light, thin and soft by modifying the structure and yarn count of the fabric, and greatly improves the unidirectional moisture-conducting capability of the fabric.

The utility model can be obtained by the above example, by utilizing the mutual interweaving of the rough yarn and the spun yarn, the spun yarn is not attached to the skin, the capillary water-guiding capacity difference of the two surfaces of the fabric is obviously enhanced, so as to achieve the purpose of keeping the skin surface of the human body dry and comfortable all the time, and meanwhile, the utility model has the light, thin, soft and differential moisture-guiding capacity. The knitted fabric can meet the requirements of people on wearing comfort, functionality and practicability, is wide in application range, and has good market prospect and economic and social benefits.
