The way to overcome the towel color

The way to overcome the towel color
 
(1) improve the uniformity of the roll. Ordinary mangle Dyer, should the car roll surface ground intermediate diameter slightly larger, slightly smaller diameter ends olive roll; a reasonable choice of hardness of the rubber roll.
(2) Padders. Production of a single species, when a single color products, color or left sides in color is a viable way to use olive roll resolved. However, in the production of small quantities, multi-species, multi-color bit varieties. Because the factors to be considered more often require frequent replacement roller Jane use it to cause trouble. Using Padders is a good way to solve the edge in color, the color of the left-right.
(3) the appropriate choice of equipment to improve the status of the device, so that the dyed throughout the dyeing process can be uniformly colored.
(4) improve the uniformity of the drying fabric. Fabric into the hot air drying machine, the size of the spray air speed and temperature level of the water evaporates different speed impact. Where the wind speed, high temperature area, water evaporates quickly, allowing fast evaporation of the dye-migration area, resulting in color. The processing of thick fabric type, temperature difference of less than 10 ℃ has little effect on the color, and the processing of thin fabric, there will be a temperature difference of more than 5 ℃ obvious color. Winds from the left-right difference within 4m / s, the impact on the thick fabric is very small. And when the wind speed difference of 2m / s, thin fabric will have a clear color. It must be taken seriously and strictly adjust the wind speed, and temperature and heating rate consistent fabric, drying fabric to make consistent, do not result in color. Hot part lateral guide rollers wear cloth way, to prevent the front and back color more favorable. Because both sides of the hot air blown from the same fabric duct. If vertical wear cloth hot air dryer, equipment modifications to make the outlet air flow into the upper and lower wind speed can be appropriately adjusted, which correct chromatic aberration. Drying cylinder drying machine is contact drying, the contact area with the drying cylinder heating up fast, fast drying, it could easily lead-migration issues. So, to make the first contact with the fabric for a cylinder temperature of suitably low number, and then gradually into the hot drying cylinder. This helps to reduce the potential chromatic aberration. To infrared drying, microwave drying, etc., can be consistent inside and outside drying dye products. Swimming helps to avoid color shift produced. When infrared drying fabric, both sides must strive even infrared radiation from the infrared radiator and the fabric is not too close, to prevent drying too fast, resulting in positive and negative color. Additionally, the front of the semi-finished stained uniform drying to make semi-finished staining consistent amount of fluid absorption, not because of water containing semi caused by uneven absorption of dyes formed uneven color (5) staining dye to be a reasonable choice. We should try to choose the dye curve similar dyes facilitate to reduce chromatic aberration. Dyeing dye used according to origin, lot number stored separately. To do a good job testing laboratory work, for each batch of dye shade hearts to do effective batches used to prevent chromatic aberration.
(6) was added levelness dyeing auxiliaries, such as adding cotton when cotton knitwear dye leveling agent administration, help reduce chromatic aberration. Polyester / cotton fabric pad when you want to add an appropriate anti-migration agents (such as sodium alginate, polyacrylic acid derivative in the dyebath) in the dyebath. This prevents color-migration has caused a certain effect.
(7) to strengthen the training of the original management, to provide qualified semi staining.
