Pneumatic bursting tester China national patent：ZL201210486480.8 ZL201220628425.3 Pneumatic bursting strength tester China national patent：ZL201210486480.8 ZL201220628425.3 [Scope of application]: It is used to measure the burst strength and burst expansion degree of various fabrics, including knitted fabrics, woven fabrics, non-woven fabrics, laminated fabrics and other fabrics made by other processes, under standard conditions or wet conditions. This method is employed to assess the burst strength and degree of burst expansion of various types of fabrics, such as knitted, woven, non-woven, laminated, and others produced through different processes, under both standard and wet conditions. This technique is utilized to evaluate the burst strength and extent of burst expansion in various fabric types, including knitted, woven, non-woven, laminated, and others produced through diverse manufacturing processes, under both standard and wet conditions. Benefits of Bursting strength tester: Fast testing cycle for fast feedback to the production • Auto-start, a photocell detects the presence of a sample and automatically initiates a measurement sequence, thus allowing hands-free operation • Auto-cycling function permits the continuous cycling of the upper pressure foot to facilitate representative and continuous measurements
  • Available with automatic test strip feeder Measurements are simple to make with the Mullen type Bursting Strength Tester. Fast automatic measurements Measurement starts automatically once a test piece has been placed in the measuring gap. The clamping foot descends, and a bursting strength measurement is made.
The sample is then quickly released and is ready for the next measurement at a new position. To maximize the sample measurement rate, the tester uses a minimum of time between the bursts, so that a series of 10 measurements can be done in less than 45 seconds. The actual measuring time depends of course on the type of paper or paper board being tested. Three Different test results can be reported after a single measurement; bursting strength standard, bursting strength compensated, and bursting energy absorption (BEA).Bursting strength tester can be compensated for the stiffness of the diaphragm For low bursting strength levels, the stiffness of the diaphragm can account for a large portion of the bursting strength value. If desired, the device can also measure, calculate, and report effective bursting strength compensated from the effects of the diaphragm. Measurement of Bursting Energy Absorption (BEA) is used to determine the energy absorption capability of a material. Strong, flexible paper has higher energy absorption values, while brittle, stiff paper has lower values. Bursting Strength Tester calculates and reports BEA according to the SCAN P 24 standard Related standards of Bursting strength tester: GB/T7742.2 (the first drafting unit of national standards) ISO13938-2, etc. [Instrument characteristics]: 1.

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.
