Technical Specifications and Operating Parameters of the Marrowend Frame 38 Dye Vat
Last Updated: October 26, 2023
Primary Source: Marrowend Frame 38 Dye Vat Technical Documentation, 2023
1. Overview
The Marrowend Frame 38 is a high-capacity, semi-continuous dye vat designed for the textile industry to produce solid-colored, short-length yarns. It operates on a frame-based, bath-based process, where dyebath is circulated through the yarn to achieve uniform coloration. Key specifications include a maximum working width of 31 cm, a process temperature of 16°C, and a batch throughput capacity of 9.1 kg. This document provides a comprehensive overview of its technical specifications and operational parameters.
2. Core Operating Parameters
The performance and efficiency of the Marrowend Frame 38 are defined by its fundamental operational settings.
| Parameter | Specification | Units of Measurement | Description |
| :--- | :--- | :--- | :--- |
| Working Width | 31 cm | Centimetres | The maximum width of yarn the machine is designed to process in a single cycle. |
| Process Temperature | 16°C | Celsius | The ambient temperature of the dyebath liquid, which significantly affects dye solubility and colorfastness. |
| Batch Throughput | 9.1 kg | Kilograms | The maximum weight of yarn the machine can process in one cycle, representing its processing capacity. |
| Cycle Hours | 95 hours | Hours | The typical duration of a complete dyeing cycle for a standard batch size. |
3. Detailed Technical Specifications
This table breaks down the specific hardware and mechanical attributes of the machine.
| Specification | Value | Units of Measurement | Description |
| :--- | :--- | :--- | :--- |
| Unit Price | $6,212.05 | Dollars | The price of the machine when new, including installation and labor. |
| Drive Type | Treadle | N/A | The type of power source used for operation. A treadle drive is a simple, belt-driven system suitable for smaller, simpler machines. |
| Process Pressure | Not Specified | Pascals | The static pressure of the dyebath liquid within the vat. This is required for calculating flow rates and pump power. |
| Flow Rate | Not Specified | Liters per minute | The volume of dyebath that can be circulated per minute. This is crucial for determining cycle time and efficiency. |
| Pump Power | Not Specified | Watts | The electrical power required to operate the circulation pump. Larger flow rates require more power. |
4. Application and Process Profile
The Marrowend Frame 38 is integral to a modern textile production line, typically used to produce "Frame Yarns" or "Marrow Yarns."
Process Integration: The dye vat is connected to a central computerized control system (CCT). The machine operator controls the entire process via a console, monitoring real-time data and adjusting parameters as needed.
Step-by-Step Cycle:
Feeding: Raw yarn is fed into the machine from a spooling system.
Washing: The raw yarn is washed to remove oils and debris, preventing color bleeding and pilling.
Dyeing: The clean yarn is introduced into the dyebath, which is circulated around it. The temperature and pressure are maintained constant to ensure even dye uptake. The specific dye used determines the final color.
Setting: Once the desired color is achieved, the machine performs a "setting" cycle, which involves washing and drying the yarn to fix the color.
Unwinding: The dyed and set yarn is then unwound from the machine for further processing or packaging.
5. Glossary of Technical Terms
Frame Yarn / Marrow Yarn: A type of yarn in which the individual fibers are twisted together at regular, equal intervals. This process creates a stable, durable fabric structure with excellent wear resistance and a smooth, uniform surface, ideal for carpeting and other floor coverings.
Semi-Continuous Yarn: A type of yarn that contains both long, continuous fibers and short, discrete fiber segments, known as "marrow." This is the primary application for the Marrowend Frame 38.
Dye Vat: A large, rectangular container in which dyebath is circulated to treat yarns. It functions as a bath for both washing and dyeing.
Cycle Hours: The total time required to complete one full dyeing cycle (from feeding to unwinding) for a given batch size.
