Powder-free paste textile chemicals, an upgrade to traditional powdered products, offer a core advantage by systematically reducing dust pollution risks through innovative physical form and process optimization. Traditional powdered dyes and auxiliaries, due to their fine particles and high fluidity, easily form suspended dust during production, transportation, and use. This not only pollutes the workplace environment but also poses safety hazards such as explosions and occupational illnesses. Powder-free paste products, by converting powders into a uniform paste, fundamentally address the dust emission problem.
During the production process, the preparation of powder-free paste textile chemicals avoids dust-generating steps such as traditional spray drying or mechanical pulverization. For example, traditional powdered dyes require a sand mill to refine the suspension into micron-sized particles before being dried at high temperatures to form a powder. This process is prone to dust emission due to airflow disturbances. Powder-free paste products, on the other hand, utilize cold granulation or emulsification technology to directly convert liquid raw materials into a semi-solid paste, reducing dust generation during the drying process. Furthermore, paste production equipment is typically equipped with a closed conveying system, isolating the entire process from raw material delivery to finished product packaging from airtight contact, further reducing the risk of dust leakage.
During transportation and storage, powder-free paste products offer significantly better stability than powdered counterparts. Traditional powdered additives are prone to static electricity generation due to friction between particles, which can cause explosions if accumulated in closed containers. However, powder-free paste products, lacking free-flowing powder, significantly reduce the risk of static electricity accumulation. Furthermore, the paste form reduces friction and collision between the material and the packaging container, avoiding the secondary dust generation caused by particle breakage during bumpy transportation of traditional powders. For example, some dye companies use vacuum-sealed cans to package powder-free paste products, which not only prevents oxidation and deterioration of the paste but also completely isolates the possibility of dust escaping.
During use, the advantages of powder-free paste textile chemicals are even more pronounced. Traditional powdered products require manual weighing and mixing, which can easily cause dust to adhere to equipment surfaces or become suspended in the air, causing cross-contamination. Powder-free paste products, on the other hand, are typically pre-dispersed and can be added directly via pumping or extrusion, reducing manual intervention. For example, in the printing and dyeing process, powder-free paste fixatives can be injected directly into the dyeing machine via pipes, eliminating the cumbersome process of dissolving and then transferring traditional powders. This not only improves production efficiency but also eliminates the risk of dust volatilization during the dissolution process. Furthermore, the high viscosity of the paste makes it easier to adhere to the fiber surface, reducing material waste caused by splashing or dripping, and indirectly reducing dust generation during cleaning.
From an occupational health perspective, powder-free paste products significantly improve the working environment. Dust pollution in the textile industry is one of the main causes of occupational diseases such as "cotton dust disease." Long-term inhalation of plant dust from cotton, linen, and other plants can cause symptoms such as chest tightness and coughing. Powder-free paste products eliminate the dust source, reducing workers' exposure to harmful particulate matter. For example, after a printing and dyeing factory switched to powder-free paste fluorescent brighteners, the concentration of inhalable particulate matter in the workshop air decreased, significantly reducing the incidence of respiratory diseases among workers.
Through innovative form factors and optimized processes, powder-free paste textile chemicals have established a comprehensive dust control system from production to use. This system not only meets stringent environmental regulations on volatile organic compound (VOC) and particulate matter (PM) emissions, but also aligns with the textile industry's green transformation efforts, providing a practical solution for improving operational safety and protecting worker health.
