[Description]:
Formaldehyde-free Fixative Color Fixing Agent is belongs to polymerization polyDADMAC, a cationic polymer. It can make up of macromolecular compound with dye, then achieve to improve soaping and rub fastness of fabrics. It can be used for color fixing for dyeing and printing of reactive dyed fabrics as cotton, linen, silk, and direct dyed fabrics.

B. Dipping process: 1-4% (O.W.F), Room temperature 40°C-60°C, PH Value:5-8, bath ratio:1:8-12,Time: 20-30 min.
[Properties]:
1. Concentrated Formaldehyde-free Fixative Fixing Agent has good color fixing property, can obviously improve the dyeing or printing of fabric soaping, washing fastness and wet rubbing fastness.
2. Can be used for much of the association between dye fixation, anti fading property, does not affect the dyeing or printing of fabric vividness. No effect for the original feel, processing fabric has excellent hydrophilic.
3. Formaldehyde-free Fixative widely used for dyeing or printing of the direct, active dye fixing finishing, good fixation effect, especially for the red dye and Cuilan dyes, particularly prominent, fixation is better than the general Formaldehyde-free Fixative.
4. The dye PH value for a wide range, acid, alkali resistance, resistance to hard water, high temperature resistance, an environment-friendly products, does not contain formaldehyde.

After the urea is applied to the soil, it can be absorbed and utilized by the crop by converting it into ammonium nitrogen under the action of urease. As urea is an amide nitrogen fertilizer, the adsorption force between soil colloids is low and the fluidity and leaching loss are strong. If urea is flushed with water, urea is difficult to be adsorbed by soil colloids and converted into ammonium carbonate or ammonium bicarbonate to exert a fertilizer effect. More loss. When urea is applied to the soil and converted into ammonium nitrogen, it loses its original stability, it is easily volatilized, and the amount of volatilization increases with increasing alkalinity of the soil. According to tests conducted on soils with a pH of 7-8, The urea began to evaporate in half a day and peaked in three days. Therefore, it should be avoided that it should be applied in depth or in shallow form. Deep application can be applied by ditching or acupuncture, applying a depth of 10 to 15 centimeters, a distance of 5 to 10 centimeters from the plant, covering the soil after application, burying it tightly, and do not water it within 2 to 3 days after application.
