Appearance:Yellow-green even powder or granule

UV absorption:1105-1181

Max UV absorption wavelength:349nm

Performance characteristics:CBS-X is a high quantum yield fluorescent brightener, its dosage is only a quarter ofbis (triazinylamino)stilbene derivatives.It has blue tone and high resistant to chlorine bleaching,hydrogen peroxide bleaching,strong acid as well as alkali.It can significantly increase the whiteness ofdetergent and soap and improve their appearance quality.Its good mobility makes cloth uniform whitening with no spots when cloth is handwashed in small ratio bath or put inwashing machine under a low temperature.It has excellent whitening effect.When applied in the cold water and warm water on cellulose fiber,polyamide,protein fiber and cotton,it has high whitening effect,whereas other fluorescent whitening agents have poor whitening effect in low temperature.Whitening quickly in a very short period can make fabric reach a high whitening effect.It has excellent dry and wet sunlight fastness as well as perspiration resistance,whereas bis (triazinylamino)stilbene derivatives can be resolved easily in the process of fabric exposure and make fabrics yellow under the effect of perspiration.After repeated washing,the effect is better,the more cloth be washed,the whitener and brighter it becomes,whereas bis (triazinylamino)stilbene derivatives become yellower,darker after repeated washing.CBS-X is insoluble in chlorinated hydrocarbons,but can be dispersed therein.

Application:

1.Applied in high-quality synthetic detergent powder,super concentrated detergent and soap industry;

2.It can also be applied as a fabric softening agent and a finishing agent separately or matched with other varieties of fluorescent whitening agents according to different needs;

3.Applied in exhaust dyeing and pad dyeing of cotton,exhaust dyeing of wool,exhaust dyeing of nylon,thermosetting dyeing of fixation,acid padding or solvent dyeing and silk dyeing with excellent fastness.Affinity to cotton is low,moderate to wool and high to silk.

Recommended dosage:

1.Synthetic detergent:

2.Textile:bath ratio 1:20 and yellowing point is 0.3%,bath ratio 1:40 and yellowing point is 0.5%.
