Although foreigners have said everything well since ancient times, don't belittle domestic things without verification. Fabric pretreatment and finishing should be carried out. Most fabrics are incomplete. Such as mercerization. This is very helpful to improve the effect and feel of cloth. Of course, the reason why merchants don't leave is simple-the fabric value is not worth leaving, and the consumers who bought it can't tell. Many people take formaldehyde as an example. In fact, formaldehyde content is almost residue-free in real reactive printing and dyeing. Many active products we export can meet Class A standards (the formaldehyde content of infants is less than 22), and only pigment printing will have more formaldehyde residues. The reason is the glue printed by the paint. This is actually not very important, just write it down. It is the technical level of sewing workers, which directly affects whether the thread is flat and whether the appearance is fashionable. Good bedding is hard to come by, and it is used and cherished.
