The mechanical parameters of the steamer are detailed as follows:
The steamer is designed to process blended yarns made from cotton, hemp, and chemical fibers. This process involves steaming and conditioning the yarn to increase humidity, enhance strength, and improve elongation at break. As a result, it minimizes warping, reduces weaving breaks, and improves the efficiency of knitting and weaving processes.
**Relaxation:**
During the unwinding process, kinks and tangles can cause yarn breakage and affect quality. Using steam-relaxed yarn significantly boosts the efficiency of subsequent operations such as winding, twisting, warping, and weaving.
**Heat Setting:**
High-twist yarns, core-spun yarns, and synthetic filament yarns require heat setting to stabilize their twist structure. The QINGSHI steaming process ensures even treatment across all layers, providing consistent results.
**Steam Shrinkage - Pre-Shrink:**
Some synthetic fibers have heat-shrink properties. The steaming process allows for balanced and controlled shrinkage, ensuring the treated yarn meets the requirements of weaving and dyeing.
**Technical Parameters:**
- Each yarn processing cycle takes approximately 2 hours.
- Different models offer varying load capacities.
- Energy consumption per ton of yarn is around 50 KWh or 150 kg of steam.
- With double steaming technology, vacuum pump power consumption is about 2 kW/h per ton of yarn.
- Working temperature range: 50°C – 158°C.
- Working pressure: -0.085 to 0.1 MPa.
- Equipped with a color touch screen and PLC control system.
- Fully automatic door opening system (optional).
**Introduction:**
The QS indirect steaming Machine is a high-precision, gentle, and uniform steaming equipment suitable for yarns and fabrics, operating from low to high temperatures. It features microcomputer control, with temperature accuracy up to ±0.5°C, ensuring precise and repeatable processes. The system minimizes condensation, delivering even and soft steaming without damaging the yarn.
After being treated with fast negative pressure saturated steam, the yarn achieves even internal and external moisture distribution, improving its quality, shape, and appearance while preserving its original style. There’s no yellowing, pollution, or tube deformation.
The QS indirect steamer uses high-quality container plates for durability, safety, and environmental protection. It features one-button start-up, excellent sealing, and a wide range of models including square and round units with various door-opening methods for easier handling and more thorough steaming.
**Process Principle and Steps:**
1. **Vacuuming:** Removes dry air from the cylinder and yarn using vacuum.
2. **Heating and Humidifying:** Saturated steam penetrates the yarn quickly, achieving equilibrium in temperature and humidity.
3. **Temperature and Humidity Balance:** The yarn is uniformly permeated by 100% saturated steam, with the inner and outer layers reaching the same temperature simultaneously. This ensures uniform moisture regain and consistent friction coefficient.
**Role and Effect of Steamed Yarn:**
The QS steaming machine is primarily used for humidification and rejuvenation of textile fibers, enhancing the overall quality of the yarn. Key benefits include:
- Increased moisture regain by 1.5–3%.
- Improved breaking strength by 15%.
- Enhanced elongation at break by 20%.
- Reduced hairiness and fly by 20%.
- Fixed slack, reducing backlash by 50%.
- Warp yarn reduction by 15%.
- Air jet loom efficiency increased by 2%.
The yarn becomes softer, the fabric surface clearer, and the dyeing more uniform. It also reduces static electricity, improves unwinding performance, and enhances the hand feel and ironing quality. The product remains stable over time, maintaining its moisture content even after long-term storage.
**Ideal Steaming Temperature Range for Different Fibers:**
- **Wet Steam:** Contains water droplets, leading to uneven humidification and potential damage.
- **Superheated Steam:** Insufficient heat, poor penetration, and risk of discoloration.
- **Saturated Steam:** Optimal choice for textile steaming, offering strong penetration, uniform heating, and no water droplets.
Producing indirect low-temperature saturated steam under negative pressure using steam or electric heating is the most scientific and accurate method. The steam generated in a sealed container ensures uniform temperature and humidity.
**Indirect Steaming System:**
- Adjustable steam temperature range: 50–120°C.
- High vapor permeability for efficient humidity control.
- Precise temperature control with a simple, energy-efficient process.
- Handles large volumes effectively, with stable product quality.
- Supports a wide range of natural and synthetic fiber yarns, as well as blended yarns.
