    Digital Yarn Twist Tester

     

    A Digital Yarn Twist Tester is a laboratory device used to measure the number of twists (turns) per unit length in a yarn. It’s crucial for evaluating yarn quality, strength, elasticity, and uniformity. The digital version offers precise, automated readings for both S-twist and Z-twist yarns.

     

    Purpose Digital Yarn Twist Tester:

    To determine twist per inch (TPI) or twist per meter (TPM) in single and plied yarns using direct untwist or untwist-retwist methods.

     

    Applications Digital Yarn Twist Tester:

    Quality control in spinning mills

    Yarn standard testing (cotton, polyester, blends)

    R&D in textile manufacturing

     

    Working Principle Digital Yarn Twist Tester:

    One end of the yarn is clamped, and the other is rotated to remove or measure twists.

    The tester counts and displays twist digitally based on length and rotation.

     

    Benefits of Digital Yarn Twist Tester:

    High Accuracy – Digital readout ensures precise twist measurements.

    Quick Testing – Faster than manual methods, increasing lab efficiency.

    Versatile Application – Suitable for single, doubled, or plied yarns.

    Reduces Human Error – Automated counting improves repeatability and consistency.

     

    Supports Both S & Z Twist – Measures both twist directions accurately.

    User-Friendly Operation – Intuitive controls and clear display simplify use.

     

    Features of Digital Yarn Twist Tester:

    Digital Display – Shows real-time twist count and length.

    Motorized Rotation- Smooth, adjustable rotation speed for controlled untwisting.

    Dual Clamp System – Holds yarn securely to prevent slippage.

    Length Measurement Scale – Built-in ruler or encoder for precise yarn length setup.

     

    Auto Stop Function – Automatically stops when yarn is fully untwisted.

    Selectable Units – Twist readings available in TPI or TPM.

     

    How to Use Digital Yarn Twist Tester:

    Prepare the Yarn Sample

    – Cut a yarn length (e.g., 250 mm or 10 inches) as per testing standard.

    – Make sure it’s free from knots or damage.

    Mount the Yarn   – Fix one end in the stationary clamp and the other in the rotating clamp.

    – Ensure the yarn is straight and under slight tension.

     

    Set the Gauge Length – Adjust the length scale or input it digitally, depending on the machine.

    Select Twist Direction – Choose S or Z direction based on the yarn’s twist.

    Start the Test – Activate the motor to untwist (or untwist-retwist, if applicable).   – The display shows the number of rotations. Read the Twist Value  – The twist (TPI/TPM) appears automatically based on the set length.

     

    Stop and Unload – Once reading is complete, stop the machine and remove the yarn.

    Record the Result – Note the reading for documentation or further analysis.

    Cone Yarn Dyeing Machine

    Cone Yarn Dyeing Machine

      A Cone Yarn Dyeing Machine is an industrial machine used for dyeing yarn wound on perforated cones. It allows dye liquor to flow through the yarn packages under pressure and temperature, ensuring deep and uniform color penetration. A Production Cone Yarn Dyeing Machine is a large-capacity, high-efficiency machine designed for dyeing yarns wound on cones in bulk. It's essential in commercial textile operations where consistent shade, penetration, and process repeatability are critical.     Purpose of Cone Yarn Dyeing Machine: To dye large batches of yarn cones efficiently and consistently.   Key Components: Dyeing Vessel:   - A vertical or horizontal pressure vessel made of stainless steel (SS 316/304), designed to withstand high pressure and temperature. Yarn Carrier (Spindles):   - Holds multiple cones arranged on perforated spindles allowing dye to pass through. Circulation Pump:  - Forces dye liquor through yarn in inward and/or outward flow for thorough penetration. Heat Exchanger: - Heats dye bath using steam or thermal fluid, with precise control.   Control System (PLC): - Fully automated for setting temperature profile, flow direction, timing, and rinsing cycles. Liquor Tanks & Valves: - For preparation, dosing, and circulation of dyes, chemicals, and water.   Working Cycle: Loading: Cones are placed on carriers and loaded into the machine. Liquor Preparation: Dye and auxiliaries mixed in a separate tank or directly. Dyeing: Liquor is circulated through cones under set temperature and pressure. Rinsing & Soaping: Post-dyeing cleaning and neutralization cycles. Cooling & Unloading: Bath cooled; cones unloaded for hydro extraction.   Production Capacity: Varies from 5 kg lab models to over 1000 kg per batch in industrial setups.   How to Use Production Cone Yarn Dyeing Machine: Preparation: - Inspect the machine for cleanliness and proper function. - Prepare dye liquor by mixing dyes and auxiliaries according to recipe. Loading Yarn: - Place yarn cones evenly on perforated spindles/carriers. - Load the carriers into the dyeing vessel securely.     Set Parameters: - Input dyeing parameters on the control panel (temperature, time, flow direction, pressure). Start Dyeing Cycle: - Begin liquor circulation and heating. - Monitor temperature and pressure for stability. Flow Control: - Switch between inward and outward liquor flow as programmed to ensure uniform dyeing. Rinsing & Soaping: - After dyeing, run rinse cycles to remove unfixed dye and chemicals.  - Soaping cycle if required for color fixation.   Cooling:  - Lower temperature gradually to avoid thermal shock. Unloading: - After the cycle completes, safely open the vessel.  - Remove dyed cones and transfer for hydro-extraction or drying. Cleaning: - Clean the vessel and filters for the next batch. Tips: Always check for uniform loading to avoid uneven dyeing.   Applications of Cone Yarn Dyeing Machine: Used in yarn dyeing mills for cotton, polyester, viscose, and blended yarns. Ideal for commercial-scale dyeing before weaving or knitting.   Working Principle: Yarn cones are stacked on spindles inside a dyeing vessel. Dye liquor is pumped through the cones (inward or outward flow). Temperature, pressure, and time are controlled digitally for accurate dyeing.   Benefits of Cone Yarn Dyeing Machine: Uniform Dye Penetration - Ensures even color across the entire yarn cone. High Productivity - Capable of dyeing multiple cones simultaneously. Efficient Dye Utilization - Recycles dye liquor to reduce waste and cost. Energy & Water Saving - Optimized cycles lower water, steam, and chemical usage. Consistent Quality - Controlled temperature and pressure ensure repeatable results. Suitable for Various Yarns - Handles cotton, polyester, viscose, acrylic, and blends.   Features of Cone Yarn Dyeing Machine: High-Pressure Dyeing Vessel - Made from stainless steel for durability and corrosion resistance. Inward/Outward Flow System - Alternating flow ensures full yarn coverage. Automatic Controls - PLC or digital panel for temperature, time, and pressure settings. Heat Recovery System (optional) - Saves energy by recycling heat from spent liquor.   Safety Mechanisms - Includes pressure relief valves and auto-locking lids. Multiple Carrier Sizes - Supports various bobbin sizes and production capacities. Follow safety procedures due to high pressure and temperature. Use proper protective equipment when handling chemicals.   Safety Tips for Production Cone Yarn Dyeing Machine: Always wear appropriate PPE (gloves, goggles, apron) when handling dyes and chemicals. Ensure the dyeing vessel lid is securely locked before starting the machine. Do not open the vessel while it is pressurized or hot. Follow emergency shutdown procedures if abnormal noise, leaks, or pressure occur. Keep the workspace clean and free of slip hazards from spilled liquids. Regularly inspect safety valves and pressure gauges for proper function. Train operators on emergency response and chemical handling protocols.   Maintenance Tips: Clean the dyeing vessel and filters after each batch to prevent residue build-up.
