The GBM beam dyeing machine for nylon fabric can flexibly switch between unidirectional and bidirectional liquid flow according to the processing requirements of various fabrics. This equipment is suitable for high-quality dyeing processing of a variety of high-end fabrics, meeting the technical requirements of high-end dyeing.
Product Features
1. The beam dyeing machine for nylon fabric features an integrated cylindrical container design and is equipped with a high-efficiency shell-and-tube heat exchanger.
2. It employs a high-efficiency radial pump to achieve internal to external liquid circulation. The equipment can flexibly adapt to variations in fabric roll diameter and width.
3. The temperature control range is 0–140℃, and the design pressure capacity reaches 5.2 bar. In terms of heating performance, the average rate of heating from 25℃ to 130℃ is 4.5℃/min (based on 7 bar dry saturated steam pressure); in terms of cooling performance, the average rate of cooling from 130℃ to 80℃ is 3℃/min (based on 3 bar, 25℃ cooling water).
4. The beam dyeing machine for nylon fabric can operate in a low liquor ratio range of 1:3 to 1:6.
Advantages
1. No mechanical tension: The fabric remains stationary during the dyeing process, without stretching or deformation, making it particularly suitable for nylon fabrics prone to curling or slipping.
2. No creases: The flat-width winding method avoids longitudinal creases caused by rope-like dyeing.
3. Low liquor ratio: The liquor ratio can reach 1:7, significantly saving water, energy, and dyes.
4. Excellent dyeing evenness: The bidirectional liquid flow reversal device ensures uniform dyeing of the inner and outer layers of the fabric.
5. Large capacity: A single cylinder can hold hundreds to thousands of kilograms, suitable for mass production.
Precautions
1. Main pump power: Must match the fabric roll diameter and density. Insufficient power will result in uneven dyeing or gradient colors.
2. Sealing: The dyeing vat must be sealed under high pressure to prevent leakage.
3. Circulation cycle: Forward circulation time is usually longer than reverse circulation. Loose fabrics can use only forward circulation.
4. Cooling control: After dyeing, the temperature must be gradually reduced to below 90°C before venting steam and draining the liquid to prevent the fabric from becoming stiff and hard.
