Environmental Protection Polyester Fabric Acid Reduction Cleaning Agent YY-RCA Development and Performance Testing

analysis

There are the following insurmountable disadvantages when using powdered contaminants:

(1) The insurance powder will spontaneously ignite, and will naturally heat up and burn when it absorbs moisture. The warehouse where the powder is stored will repeatedly burn and form a fire.

(2) During the stripping of the insurance powder, sulfur dioxide gas is released, causing environmental pollution in the workshop and impairing the health of the workers. Some factories expressly provide for working in dyeing workshops for up to three years to avoid occupational diseases.

(3) The insurance powder is unstable at high temperature, and the most suitable stripping temperature cannot exceed 70°C, otherwise it will fail due to decomposition too quickly.

(4) The decomposing rate of the insurance powder in the acidic medium is accelerated, and it is not suitable for the stripping of the acidic medium. In particular, in the stripping of wool and silk fabrics, a small amount of soda ash is required to maintain the pH at about 8, even if it is still damaged Hair and silk, resulting in decreased strength.

(5) The storage stability of the insurance powder is poor, and it will decompose in the air, resulting in continuous decline of the active ingredient.

Therefore, people are looking for a substitute for the chemical powder to overcome the above shortcomings. Haining Yuanyuan Textile Auxiliary Co., Ltd. has successfully developed the environment-friendly polyester fabric acid reduction cleaning agent YY-RCA which is a benzene sulfonic acid type reducing cleaning agent and plays a role in acidic conditions. For disperse dyes do not release water after the reduction cleaning.

Test item: Restore cleaning ability.

Test Experiment: Scattered Restore Test

Polyester dispersion dyeing was cooled down to 85°C without adding water and acid was added to adjust the pH to 4.5. Then a reducing cleaning agent (powder) was added. Keep warm for 20 minutes. Remove the color sample and test the water fastness before/after the test.

The dyeing formula Longsheng disperses red GS 200% 3.0%, Leveling agent PLD 1.0g/l, Acid releasing agent AB 2g/l. 130°C×45′.

in conclusion:

1. The environment-friendly polyester fabric acid reduction cleaning agent YY-RCA has a stronger ability to reduce and clean than traditional caustic soda insurance powder process.

2. The amount of YY-RCA, an eco-friendly polyester fabric cleaning agent, can achieve a good reduction cleaning effect when the dosage is 0.5-0.8.
