Description

SiKJ-1860 is 60% active silicone quaternary ammonium salt which act as an general use anti-microbial agent for all kinds of natural and synthetic fibers.

Features

• Excellent antimicrobial activity in finished product

• Laundry-resistant, providing durable odor control and fabric protection

• Environmentally friendly and safe, non-irritating to skin

Product data

Notes: these data are for reference only and should not be used as preparation specifications.

Application

SiKJ 1860 is effective against Gram-positive bacteria, Gram-negative bacteria, fungi, algae, and yeasts. By inhibiting the growth of bacteria and mold, it provides a fresh, hygienic feel and resists odor generation. SiKJ 1860 can be used for antimicrobial finishing on various textiles, including:

• Natural fibers: cotton, linen, wool, silk

• Synthetic fibers: polyester, nylon, acrylic, vinylon, spandex

• Blended fabrics: cotton/polyester, wool/polyester, cotton/acrylic, etc.

How to use

SiKJ 1860 can be applied to fibers and textiles through padding, exhaust, spraying, or roller coating.

• Depending on the antimicrobial performance required, the dosage of SiKJ 1860 is approximately 0.25% - 3% (owf, on weight of fabric).

• It is recommended to dilute with warm water (25°C to 50°C) and stir thoroughly to activate the product, preparing a working solution of 2% - 5% SiKJ 1860.

• SiKJ 1860 may solidify at a low temperature, warm to melt and stir before dilution and use.

• SiKJ 1860 is incompatible with anionic surfactants. For other types of auxiliaries, compatibility testing is recommended before use.

• To ensure durable antimicrobial effects, proper baking (curing) is required after application.

Typical Process Example (for polyester/cotton or blended woven fabrics)

• Preparation of working solution: Typical application dosage of SiKJ 1860 is 2% - 3% of fabric dry weight. Add the concentrate to deionized water at 25°C - 50°C and stir to dissolve, preparing a 2% - 3% working solution. The pH of the working solution should be adjusted to 6.0 - 7.0.

• Add the diluted and activated working solution to the final padding bath. The actual bath concentration depends on the fabric's wet pick-up (wpu%).

• If mixing with other finishing auxiliaries (e.g., softeners, moisture-wicking agents), mix thoroughly before use.

• Pad the fabric.

• Drying and curing: Cure at 150°C - 160°C for 3-5 minutes (depending on fabric type).

Rapid Wash Resistance Test (Bromophenol Blue Indicator Method)

Drop a few drops of dilute bromophenol blue indicator onto the antimicrobial finished fabric. Dry at 110°C, then launder several times. Observe whether the blue color remains on the fabric:

- Blue color present: antimicrobial agent is still effectively bound.

- Blue color disappeared: antimicrobial agent has been washed off.
