    Flannelette can be divided into two categories according to the processing method: natural flannel and dyed flannel. Yarn-dyed flannel can be divided into single noodle velvet, double-sided corduroy, double-sided embossing, lining, color velvet, double weft, and fleece. The flannel fabric is mainly a weft yarn, and the warp and weft yarn density ratio of the single velvet is usually 1:1.5 to 1:2; the warp and weft yarn density ratio of the double jersey is about 1:2. 
     
    The thick velvet uses a weft yarn of 58.3 tex or more, and the thin velvet uses a weft yarn of 58.3 tex or less. From the effect of the fluff, the velvet fabric is preferably low-twisted under the condition of satisfying the latitudinal strength. 
     
    The warp and weft yarns have different twists, which make the fabric feel thick and soft, and the fluff is evenly distributed. The weft tightness of the flannel is greater than the tension. Generally, the warp and weft tightness ratio of the double velvet is about 1:1.7, and the warp and weft tightness ratio of the single velvet is 1:1.2 to 1:1.7. 
     
    The velvet fabric has large difference in warp and weft density, small weft twist and soft texture. After fluffing and scraping finishing, fluff is formed on the surface of the grey fabric. The surface of the fabric is fluffy and the air layer is increased, so that the thermal conductivity is reduced and the warmth is enhanced.
