In which industries and processes is the environmentally friendly penetrant JFC mainly used?

The environmentally friendly penetrant JFC is widely used in multiple industries such as textile printing and dyeing, leather processing, papermaking, industrial cleaning, pesticide preparations, and water-based coatings, with core applications involving key process steps such as penetration, wetting, and emulsification.

Detailed Description

The environmentally friendly penetrant JFC (fatty alcohol polyoxyethylene ether, CAS No.: 68439-50-9) is a non-ionic surfactant, appearing as a colorless to slightly yellow transparent liquid. With its excellent penetrating power, wettability, and emulsifying ability, as well as outstanding resistance to acids, alkalis, hard water stability, and wide compatibility, it has become an indispensable functional aid in many industrial fields.

This product is suitable for a wide range of pH values and complex water quality conditions, maintaining high performance in acidic, alkaline, or neutral systems, and can be used compatibly with other types of surfactants and auxiliaries. In addition, its low-foaming characteristic makes it particularly prominent in foam-sensitive processes such as high-speed overflow dyeing.

Industry Applications and Process Details

I. Textile Printing and Dyeing Industry

In the pretreatment processes of cotton, linen, chemical fibers, and their blended fabrics, the environmentally friendly penetrant JFC plays a core penetrating role:

• Desizing process: Accelerates the penetration of the desizing solution between the fiber and sizing interface, promoting the swelling and removal of the sizing agent.
• Scouring process: Quickly wets the fibers, allowing the alkali liquor to penetrate evenly into the yarn interior, significantly improving capillary effect and whiteness.
• Bleaching process: Helps the bleaching solution penetrate uniformly, improving bleaching uniformity and whiteness consistency.
• Dyeing process: Its low-foaming property is suitable for high-speed overflow dyeing equipment, reducing foam interference.

II. Leather Processing Industry

In the soaking process of raw hides, it accelerates the penetration of water into the fiber interior of the leather, shortening soaking time and promoting the dissolution of salts and soluble proteins in the leather; in the degreasing stage, used in combination with alkaline auxiliaries, it effectively emulsifies and removes natural oils without damaging the grain layer of the leather surface, ensuring the quality of the finished leather.

III. Papermaking Industry

In the deinking process of waste paper, it serves as a penetrating and emulsifying aid, quickly wetting ink particles and penetrating into the fiber-ink interface, cooperating with flotation or washing methods to strip ink from the fiber surface and disperse it in water, improving the brightness of deinked pulp and reducing fiber loss.

IV. Industrial Cleaning Field

Suitable for water-based cleaning formulations for hard surfaces such as metal parts, molds, and pipes, with excellent penetrating power to penetrate into the gaps between oil stains and the substrate, synergistically with surfactants to quickly roll off and emulsify heavy oil dirt, maintaining good cleaning efficiency even at room temperature.

V. Pesticide Preparation Industry

Used as a wetting and dispersing component in wettable powders (WP) to improve the wetting speed and suspension rate of technical drug particles in water; in emulsifiable concentrate (EC) formulations, it serves as an auxiliary emulsifier, improving the auto-dispersibility and dilution stability of the emulsion, reducing spray drift, and enhancing field application effects.

VI. Water-Based Coatings and Inks Industry

In emulsion paints, water-based wood coatings, and water-based ink systems, it quickly wets the surface of pigments and fillers, assisting mechanical shear to achieve efficient deagglomeration and stable dispersion, preventing pigment paste re-agglomeration and floating/flooding, while reducing the dynamic surface tension of the system, improving spreading and leveling on the substrate.

Application Recommendations

Recommended application processes and directions for various industries:

• Textile Printing and Dyeing: Recommended to add 0.5~5 g/L in the pretreatment bath, with specific dosage adjusted according to fabric type and process requirements.
• Leather Processing: Add 0.3%~1% based on leather weight in the soaking process, and use in combination with alkaline auxiliaries in the degreasing process.
• Papermaking Deinking: Add 0.1%~0.5% based on the weight of oven-dry waste paper in the pulping or flotation stage.
• Industrial Cleaning: As a penetrating synergy component in cleaning agent formulations, recommended addition amount is 1%~10%.
• Pesticide Preparations: Add 2%~5% as a wetting agent in wettable powders, and use as an auxiliary emulsifier in emulsifiable concentrates as appropriate.
• Water-Based Coatings: Add during the grinding and dispersion stage, at 0.1%~1% based on the total formulation weight.

Precautions

• Safety Protection: Wear protective gloves, goggles, protective clothing, and face shield during operation to avoid direct contact with skin and eyes (H315: Causes skin irritation; H319: Causes serious eye irritation).
• Ventilation Requirements: The workplace should maintain good ventilation to avoid inhaling vapors or mist.
• Environmental Protection: This product is harmful to aquatic life with long-lasting effects (H412). Do not discharge directly into sewers, surface water, or soil.
• Storage Conditions: Recommended storage temperature is 5°C to 40°C, store in a cool, dry, and ventilated place, keep container tightly closed, avoid direct sunlight, and store separately from strong oxidizers, strong acids, and strong bases.
• Emergency Measures: In case of skin contact, rinse with plenty of water; in case of eye contact, rinse with clean water or saline for at least 15 minutes and seek medical attention immediately; in case of leakage, absorb with inert absorbent material and collect, dispose of as hazardous waste.
