I. Standard Operating Procedures are Fundamental
1. Precise Control of Process Parameters: Strictly set and monitor temperature, liquor ratio, time, and number of passes to avoid color differences and uneven coloring caused by parameter fluctuations.
2. Correct Use of Dyes and Auxiliaries: Ensure dyes are fully dissolved and evenly mixed; add dyes according to their properties, and apply a top coat for volatile dyes.
3. Fabric Treatment and Loading: Fabrics must be pre-treated and kept flat; maintain even tension during loading, avoiding folds or overlaps; ensure seams are flat and the fabric width is aligned.
II. Equipment Maintenance is Key
1. Regular Inspection and Maintenance: Frequently inspect fasteners, guide rollers, fabric winding rollers, tension devices, etc., and address any abnormalities promptly. Clean the dye bath regularly to prevent dye sedimentation.
2. Safety Device Maintenance: Ensure that safety devices such as cylinder inlet safety baffles, emergency stop devices, and pressure gauges are in good working order.
III. Environment and Management as Guarantees
1. Equipment Installation Environment: Equipment should be placed on a flat, firm foundation and secured with anchor bolts to ensure it is level.
2. Personnel Training and Management: Operators must undergo safety training and pass the assessment, and be familiar with equipment operating procedures and emergency response. Establish a shift handover inspection system and maintain a clean environment around the equipment.
IV. Risk Identification and Prevention
1. Electrical Risks: Regularly inspect power cords and electrical wiring to ensure proper grounding and prevent electric shock or fire.
2. Mechanical Risks: Check the protective covers of transmission parts for integrity to avoid mechanical injuries.
3. Burn Risks: When operating high-temperature and high-pressure equipment, personal protective equipment must be worn, and safety baffles should be installed at the cylinder inlet.
