1. Generally, it depends on whether the
high quality woven fabric is delicate and the velvet is even;
The weft density of the fabric is larger and the warp density is smaller, so that the yarn can emerge on the surface of the fabric, which is conducive to the formation of rich and uniform fluff in the weft and cotton thread! Observe whether the hair surface effect is delicate, erect and supple.
2. The density of the plush is grammage, and the hand feel is smooth or not;
The flannel is made by pulling the fibers of the yarn body out of the yarn body through a napping machine, and evenly covering the surface of the fabric, so that the fabric presents a rich and fluffy cotton fabric. Observe whether there is any messy hair on the surface of the fabric.
3. The quality of the original yarn and the quality of weaving affects the softness effect;
The fleece is raised by the repeated action of the wire needle tip of the fleece machine, and the fleece formed by pulling up a part of the fiber on the surface of the grey cloth is required to be short, dense and even. Observe whether the villi are short and dense.
4. Dyeing accuracy and color brightness;
The flannel mercerizing process can increase the vividness of the pattern and improve the printing effect of the calico. Bleached velvet and dyed velvet generally need to be padded with softener separately before raising, and bleached velvet should be appropriately whitened with whitening agent and paint blue liquid. Observe whether the color of the surface of the fabric is uniform.
5. Other undesirable phenomena such as abnormal indentation, wavy lines, and disordered hair direction can also be observed for the fabric surface effect.
