Woven fabric in the process of finishing after printing, there may be some flaws. Different factors have different phenomena, understanding that this information helps improve in production, thereby improving the quality of printing and dyeing of the woven fabric. In combination with the actual situation, it is analyzed that a common kind of is oil droplet staining.
From the look, this kind of flaw is more common in the woven fabric of the E / R blended material, and there is a spots of oil droplets after dyeing, and the color is slightly deep. Observe the magnifying glass, the plush of the fabric concentrate, exhibits a micro-bead shape, and a plush than the normal part. The main reasons for this situation are: woven fabric treatment is not uniform in the burn-in order, resulting in a staining concentrating site, plush failure to be fully burned, and become a combusing group, stronger color absorption, so staining concentrated.
The second kind of flaw is called soaking and unopened, and the main phenomenon is that after the woven fabric is stained, there is a dark color cloud shape. The mainly included reasons are: 1, denture, fine slurry is not enough, or treated with a gangqua equivalent,Wholesale Custom spandex fabrics Manufacturers then attached to the fabric; 2, the bath is too small when the bath is infected, the temperature rise rate is too fast
The staining liquid is in a native condition. In addition, during the closing fabric dyeing process, there may be problems such as drifting holes. At this time, it can be seen that its embryo is normal. After the hydrogen peroxide is bleached, the layout has a vapor yarn or The weft cleavage is broken to form a small hole. In fact, the main reason for this problem is that there are some rust above the woven fabric, or the bleaching bath contains iron ions, and during the woven fabric maturity process, the gauze is broken.
