The steamer is an essential piece of equipment used in the textile industry to improve yarn quality through controlled steam treatment. It is designed to process a wide range of fibers, including cotton, hemp, and synthetic blends, enhancing their physical properties such as strength, elongation, and moisture absorption. This process significantly reduces issues like yarn breakage, warping, and uneven dyeing, ultimately improving production efficiency.
**Relaxation Process:**
During the unwinding of yarn, kinks and tangles can lead to breakage and poor quality. Steam relaxation helps to straighten and untangle the fibers, making subsequent processes like winding, twisting, and weaving more efficient and less prone to defects.
**Heat Setting:**
High-twist yarns and core-spun yarns require heat setting to stabilize their twist and prevent deformation during further processing. The QINGSHI steaming system ensures even treatment across all layers, maintaining consistent quality.
**Pre-Shrinkage Treatment:**
Some synthetic fibers have a tendency to shrink when exposed to heat. The steaming process allows for controlled and uniform shrinkage, ensuring that the yarn meets the requirements for weaving and dyeing without distortion.
**Technical Specifications:**
- Each batch of yarn typically requires about 2 hours of processing time.
- Different models offer varying load capacities.
- Energy consumption per ton of yarn is approximately 50 KWh or 150 kg of steam.
- With double steaming technology, the vacuum pump consumes around 2 kW/h per ton of yarn.
- Operating temperature: 50°C to 158°C
- Operating pressure: -0.085 to 0.1 MPa
- Equipped with a color touch screen and PLC control for precise operation.
- Fully automatic door opening system (optional).
**Introduction:**
The QS indirect steaming Machine is a high-performance device designed to provide uniform, gentle, and accurate steam treatment for both yarns and fabrics. It uses microcomputer control to ensure precise temperature regulation within ±0.5°C, guaranteeing consistent and repeatable results. The system minimizes condensation and delivers even steam penetration, preserving the original texture and appearance of the yarn without yellowing or damage.
After being treated with fast negative pressure saturated steam, the yarn is evenly moistened from the inside out, improving its shape, softness, and overall quality. The machine features durable, high-quality container plates that are safe, eco-friendly, and resistant to pressure. It starts with a single button, has excellent sealing, and offers multiple configurations, including square and round designs, various door-opening methods, and convenient yarn conveyance.
**Process Principle:**
1. **Vacuuming:** Removes dry air from the cylinder and yarn.
2. **Heating and Humidifying:** Saturated steam penetrates the yarn quickly, achieving equilibrium in temperature and humidity.
3. **Temperature and Humidity Balance:** The yarn is fully saturated with steam, ensuring uniform heating and moisture distribution across all layers.
**Benefits of Steamed Yarn:**
- Increases yarn regain by 1.5–3%
- Boosts breaking strength by 15%
- Enhances elongation at break by 20%
- Reduces hairiness and fly by 20%
- Minimizes slack and backlash by 50%
- Reduces warp yarn by 15%
- Increases air-jet loom efficiency by 2%
- Improves fabric surface clarity, dyeing uniformity, and reduces static electricity
- Enhances yarn unwinding and hand feel
**Ideal Steam Temperature Range:**
- **Wet Steam:** Contains water droplets, which may damage the yarn.
- **Superheated Steam:** May lack sufficient moisture and cause discoloration.
- **Saturated Steam:** Offers optimal performance, with no water droplets, strong penetration, and uniform heating.
Producing low-temperature saturated steam under negative pressure using steam or electricity is the most scientific and efficient method. The resulting steam provides uniform temperature and humidity, ideal for textile applications.
**Indirect Steaming System:**
- Adjustable steam temperature range: 50–120°C
- High permeability for effective humidity control
- Precise temperature regulation
- Efficient, energy-saving, and environmentally friendly
- Suitable for natural and synthetic fibers, as well as blended yarns
