I. Daily Maintenance 1. Check Lubrication: Inspect gears, bearings, and other moving parts daily, and replenish lubricating oil (such as lithium-based grease) promptly to prevent dry friction damage.
I. Fabric Quality Problems 1. Color Difference Phenomenon: Inconsistent color depth in the fabric, including differences in color intensity between the edges and center, left and right, front and back
I. No-load test run 1. Equipment inspection: Confirm that the nozzle gap is uniform to avoid inconsistencies between fabric speed and dyeing volume. Check the functions of the main pump, dye addition
I. Daily Inspection and Cleaning 1. Operational Status Inspection: Before starting the machine each day, listen for abnormal noises from the motor and reducer, and check the temperature of the casing
I. Chemical Cleaning Methods 1. Caustic Soda Cleaning: Use 4-6 kg of 98% caustic soda and treat at 130℃ for 60 minutes. This effectively removes residual dye and oil stains, especially suitable for th
I. Pre-Operation Preparation 1. Equipment Inspection: Confirm that the nozzle gap is uniform to avoid inconsistencies between fabric speed and dyeing volume. Check that the main pump, dye addition pum
I. Pre-Operation Preparation 1. Equipment Inspection: Confirm that the nozzle gap is uniform to avoid inconsistencies between fabric speed and dyeing volume. Check that the buttons on the main pump, d
I. Temperature Control 1. Heating Rate: It is recommended to control the rate at 1℃/min to avoid uneven dyeing caused by excessive speed. 2. Holding Stage: For light colors, hold at 50-60℃ for 15-20 m
1. Color variations and uneven color distribution Causes: Dye not fully dissolved, excessively rapid heating, residual auxiliaries on the fabric, or uneven pH. Solutions: Use cold water to sizing and
I. Pretreatment 1. Blanching/Bleaching: Add a lubricant (such as a bleaching agent) to reduce fabric friction and prevent creases, especially important for thin cotton fabrics under 150 grams. Place t
I. Factors Affecting Troubleshooting Time 1. Fault Type: Simple faults (e.g., abnormal tension, guide fabric misalignment): Can be resolved within 1 hour. Complex faults (e.g., color difference, mecha
I. Daily Inspection: Quickly Identify Anomalies Before starting the machine each day and during operation, operators should focus on checking the following parts: 1. Mechanical System: Listen for abno
