This utility model discloses a printed fabric, relating to the textile field. The key technical points are: it includes a printed layer and a base layer. The base layer has several longitudinal and several transverse raised strips on one side near the printed layer. The thickness of the base layer reaches its maximum at the intersection of the longitudinal and transverse raised strips, forming a gap between the base layer and the printed layer. In this utility model, the overlapping longitudinal and transverse raised strips make the contact surface between the base layer and the printed layer appear as a discrete dot matrix, thus ensuring that interconnected longitudinal and transverse flow channels are formed between the printed layer and the base layer. Therefore, when the breathability of the printed layer decreases locally due to ink, this part can connect with adjacent areas with better breathability through the longitudinal and transverse flow channels. The printed layer is relatively thin, ensuring the overall breathability of the fabric. Simultaneously, the base layer, made of polyester fiber bundles, has a good cooling sensation.

The utility model discloses a sweat dredging type moisture absorption and sweat releasing fabric which comprises a breathable base material, a dredging layer is arranged on one side of the breathable base material, and a wave layer is arranged on the other side of the breathable base material. According to the sweat dredging type moisture absorption and sweat releasing fabric, due to the cooperation of the breathable base material, the dredging layer and the wave layer, on one hand, the original breathability of all parts is reserved, and on the other hand, due to dredging of the dredging layer, local sweat can be rapidly transmitted to all positions, namely, the local sweat is dredged, so that the moisture absorption and sweat releasing effects are improved, and the moisture absorption and sweat releasing effects are improved. The surface area and the local sweat absorption capacity are increased, evaporation and adsorption of sweat are facilitated, residual sweat on the skin surface is reduced, comfort is improved, in the stirring process of the wave layer, flowing of airflow in the sweat dredging type moisture absorption and sweat releasing fabric can be accelerated, evaporation and heat absorption of sweat are facilitated, and the cool feeling is improved.

This invention discloses a fabric and its preparation method. The fabric preparation method includes the following steps: functional yarns are interwoven as warp and weft yarns respectively to obtain a fabric with a tightness greater than or equal to 70%; the functional yarns are wound into a cylindrical composite material roll by a composite material layer, and then the composite material roll is stretched along its axial direction; the composite material layer includes a first material layer and a second material layer, and the winding is performed by curling along one long side of the first material layer or the second material layer towards the other long side. The fabric and its preparation method of this invention, by winding and stretching the composite material layer to obtain the functional yarn, produce a fabric with good cooling and UV protection effects, and does not require compounding with other functional fibers, post-treatment, or coating, thus providing both good cooling and UV protection.
