Core Structure and Process Applications of Pre‑treatment Combined Machines for Textile Printing and Dyeing

Pre‑treatment in textile printing and dyeing is a foundational process that determines the quality of fabric dyeing and printing. The desizing‑scouring‑bleaching combined machine, as the core equipment, integrates three sequential operations—desizing, scouring, and bleaching—enabling continuous pre‑treatment of greige fabrics and finding widespread application in processing cotton, polyester‑cotton, and viscose fabrics. The entire machine adopts a modular, building‑block design, comprising five major modules: the fabric feeding unit, the padding unit, the steam‑soaking reaction tank, the multi‑compartment rinsing unit, and the drying‑and‑unwinding unit. Each module is driven by servo‑based synchronous transmission, with tension fluctuations kept within 10 N throughout the process, thereby preventing defects such as wrinkling and weft skew in elastic fabrics.

Intelligent Textile Printing and Dyeing Machinery Control Systems and Industrial Internet Applications

An intelligent control system serves as the “brain” of modern textile printing and dyeing machinery. Centered on PLC programmable controllers, multi-sensor data acquisition, and industrial IoT, it enables end-to-end digital monitoring and control across pretreatment, dyeing, printing, and finishing processes, replacing traditional manual adjustments and significantly enhancing production stability and operational efficiency. Conventional printing and dyeing equipment relies on manual recording of temperature, machine speed, and chemical dosages, leading to substantial parameter inaccuracies and an inability to replicate processes consistently. In contrast, smart systems equipped with distributed control architectures automatically log process data throughout the entire workflow, creating a unique digital record for each fabric‑specific process. During repeat production, these records can be recalled with a single click, boosting first‑pass yield to 95%.

Technical classification of printing and dyeing machinery at home and abroad

In the past two years, new dyeing and finishing processes, new technologies, and new equipment have continuously emerged at home and abroad, showing the vigorous development of the printing and dyeing machinery industry. Energy saving, environmental protection and high efficiency are the sustainable development direction of the dyeing and finishing industry in the 21st century. New technologies and automation technologies such as short process, waterless processing technology, non-plate printing technology, low temperature plasma treatment and so on are the development trends of dyeing and finishing machinery in the future.

Structural Principles of Stretching and Setting Machines and Key Points for Intelligent Energy-Saving Retrofitting

The stenter is a core piece of equipment in post‑dyeing finishing. After dyeing and printing, fabrics undergo setting to achieve width calibration, thermal shrinkage stabilization, and improved hand feel; it can also integrate functional finishing processes such as water repellency, antibacterial treatment, and softening, directly determining the dimensional stability and visual quality of the finished product. The machine is divided into four sections: the fabric‑feeding nip rollers, the pre‑drying zone, the high‑temperature setting oven, and the cooling and fabric‑unwinding section. Fabric gripper chains clamp both edges of the fabric, gradually stretching it to the standard width, followed by heat setting at 180–220°C to relieve internal fiber stresses.

Comparison of Traditional Rotary Screen Printing Machines and Digital Direct-to-Garment Printing Machines

Printing machinery is broadly categorized into two major systems: traditional screen printing and digital inkjet printing. Rotary screen printers are ideal for high-volume, standardized production, while digital direct‑to‑fabric printers cater to small‑batch, personalized customization. Each type of equipment offers distinct technical advantages, meeting the diverse demands of today’s textile market.

Working Principle of Air‑Flow Dyeing Machines and Their Energy‑Saving Advantages at Low Bath Ratios

Air‑jet dyeing machines are the mainstream batch‑type dyeing equipment in today’s textile printing and dyeing industry. With their ultra‑low liquor ratio, low tension, and excellent levelness, they command over 60% of the market share for new production lines and are the preferred choice for knitting, stretch, and lightweight high‑end fabrics. Their core innovation lies in replacing conventional dye liquor with high‑pressure air to drive the fabric; only a small amount of dye liquor remains in the vessel, while a blower generates a high‑velocity airflow that entrains and suspends the fabric in continuous circulation, completely eliminating fabric surface damage caused by mechanical roller‑shaft traction.
