Quality requirements

The ramie sewing thread is mostly the original color, generally coiled into coils or bobbin forms, and also has a small amount of strands. Each pack has a mass of about 0.5 kg. The high-quality castor line in the international market is more stringent. The single yarn knot of each strand is glued with adhesive to remove the single yarn knot; after multiple strands are twisted together, it is treated with light pulp and bristles, all the yarn hairiness is tightly adhered, the strips are smoother and smoother, and they are twisted and twisted. After the line is twisted and checked, the appearance defects are removed and then the group color is formed. It is mainly used to sew leather products, flannel, hoses, hoods, and military products.
