[0024] The present invention will be described in further detail below in conjunction with specific examples, but the present invention is not limited to the following examples.
[0025] Such as figure 1 , figure 2 , image 3 , Figure 4 The shown moisture-absorbing and sweat-wicking fine-denier polyester fabric is composed of 50D / 24F / 37i sea-island type bicomponent composite polyester filaments, and the composite ratio of the island phase to the sea phase is 80:20. It includes the following steps carried out in sequence:
[0026] (1) Two-for-one twisting: after winding, use one-step elastic two-for-one twisting machine to process the raw materials with two-for-one twisting. The twist degree of two-for-one twisting is 8T / cm, the twist direction is S twist, and the temperature of the hot box is 185°C. , the false twist twist is 3000T / m, the two-for-one twist tension is 0.3~0.35cN / D, and the false twist tension is 0.2~0.25cN / D.
[0027] (2) Sectional warping: the warping ...
