Browning is the oxidation of China 300D fabric Manufacturers

Browning is the oxidation of China 300D fabric Manufacturers a sugar called lignin. This dissolves in water or cleaning solutions and wicks to the surface during drying. Alkalinity will greatly accelerate cellulosic browning. Over-wetting, slow drying and the age of the fabric also increase the likelihood and severity of browning

Be aware of the fiber(s) you are dealing with. Jute backed carpets make up only a small percentage of the carpets you will clean. Woven carpet and area rugs are likely to have cotton foundation yarns. Cellulosic fibers are more common in upholstery fabrics.

Browning occurs on the tips of carpet tufts or on upholstery fabric. This will be more noticeable on light colored fabrics. Browning can be caused by many factors. Sometimes it can be removed; sometimes not. Learn the proper way of dealing with this concern to succeed very well.

If uncertain of the fiber content, do a burn test and check technical aspect. Use a neutral or acid side carpet cleaner if it will provide sufficient cleaning ability. If you use an alkaline cleaning agent, neutralize by rinsing with an acid side product.

Dilute Citric Acid at 8-10 tablespoons per gallon of hot water.

Using a pump-up sprayer (or trigger sprayer for small areas), lightly mist the Citric Acid solution. Do this as lightly as possible.

Once the area is dry, vacuum it aggressively. Citric Acid dries like fine sand and can be troublesome to vacuum.

Warning: Always test materials for colorfastness, follow label directions, and never mix products unless specified in the label directions. Each situation reacts differently and results may vary.

In severe cases of browning it may be necessary to lightly re-clean the entire area in order to loosen the oxidized sugars.Remember, moisture and alkalinity caused this problem. Use a neutral carpet cleaner and be careful to control the moisture.
