Evclean LPT0006 Unlocks Low-Temperature Yarn Pretreatment at 60°C

Low-Temperature No-Drain Scouring Agent for Pretreatment
In recent years, dyeing and finishing mills have faced ever higher demands for refined operations, and saving energy and reducing consumption has become key to competitiveness. In a mill's cost structure, energy — water, electricity and steam — accounts for as much as 30%, making it a priority for improvement. At the first stage of dyeing and finishing — pretreatment — conventional high-temperature scouring is not only time- and energy-intensive but also tends to damage the yarn.
To address this industry pain point, Shandong Ever Biotechnology Co., Ltd. has launched its newly developed low-temperature, no-drain scouring agent for yarn pretreatment — Evclean LPT0006 — a new low-temperature solution for yarn pretreatment.
01 The Four-Step Cooling Evolution of Conventional High-Temperature Processes
Early conventional processes used high-temperature scouring at 98°C for up to 240 minutes; as processes improved, shorter treatments at 105–110°C emerged, followed by processes at 98–100°C and 80–100°C. Limited by the performance of auxiliaries, however, the temperature could not be lowered substantially.
Evclean LPT0006 is the company's latest low-temperature, no-drain scouring agent for yarn pretreatment. It is suitable for package yarn pretreatment, especially for the low-temperature pretreatment of medium and dark shades. Its launch brings the pretreatment temperature down to 60°C. The core breakthrough lies in “dyeing directly after scouring without draining,” which overcomes the limits of conventional processes.
02 Strong Penetration at Low Temperature: Three Core Mechanisms
How does it achieve efficient scouring at low temperature? LPT0006 builds its technical edge on three mechanisms:
• Strong penetration at low temperature: a highly penetrating agent allows the treatment liquor to enter the fiber quickly even at low temperature.
• Efficient emulsification: waxes and oils on the fiber are emulsified into a stable system and removed thoroughly.
• Dispersing and washing: stripped impurities are prevented from redepositing on the yarn, ensuring clean yarn after treatment.
03 Lower Cost, Higher Efficiency: Five Comparative Advantages
Compared with high-temperature scouring, LPT0006 delivers not only a lower process temperature but also tangible production benefits:
• Less yarn damage: low weight loss, no loss of yarn strength, and better hand feel after treatment.
• Lower energy costs: steam and water consumption are greatly reduced.
• Lower yarn weight loss: protects the fiber and improves the finished-product yield.
• Higher production efficiency: shorter process time, with direct dyeing and no draining.
• Higher dye yield: creates favorable conditions for subsequent dyeing and improves medium and dark shade results.
04 Energy Cost per Ton of Yarn and Customer Trials
Estimates show that, compared with conventional processes, the 60°C low-temperature scouring process — a temperature difference of 40°C — saves RMB 156 in steam, RMB 72 in water and RMB 16 in electricity per ton of yarn: a total energy cost saving of RMB 244 per ton of yarn.
In customer applications, the process has been validated on large single-package yarns of 1.86–2.04 kg; the treated yarn is shown in the photos.
With lower temperature, a shorter flow and better quality, Evclean LPT0006 helps dyeing and printing enterprises break through energy bottlenecks. Industry colleagues are welcome to visit the mill for trial runs and discussion, and to explore a green, low-carbon path for dyeing and finishing together.
