Moisture-absorbing heating light thin warm double-sided napped fabric and preparation process thereof

The invention relates to the technical field of novel fabric preparation, in particular to a moisture-absorbing heating light thin warm double-sided napped fabric and a preparation process thereof. The fabric is woven by selecting and using yarns of 40S/1 Siro spinning yarns, 70% viscose regenerated cellulose fibers and 30% bulky acrylic fibers and 20D elastic fiber polyurethane through a single-sided tucking and looping bead weaving method; the ultrathin light warm double-sided napped fabric with the moisture-absorbing and heating functions and the excellent warm effect is prepared in combination with a dyeing and finishing process and a post-treatment napping process; the core technology center is that unique moisture-absorbing heating fiber proportion spinning and light thin breathableweaving processes are adopted; and finally, the unique double-sided napping process improves the fluffy feeling of the fabric so as to enhance the moisture-absorbing and heating performance and the heat preservation rate of t
