PROPERTY:
Optical Brightener CXT is regarded as one perfect agent used in detergent industry.Because it induce on morpholine base into its molecular,thus improved its properties.such as improved its acid and perborate resistence.It can be used in the whitening of cellulose fiber,polyamide fiber and fabrics.it show nionic character and has optical blue color.it has better resistence to chloride bleaching tan VBLand 31#,the most favorable dyeing bath PH value is 7-10.its sunlight resistence is 4grade.The most advantage it used in detergent industry is its high matching capacity,high accumulated washing whiten effect.So it can satisfy the requirements of various matching capacity in detergent industry.
APPLICATION:
1.Whitening agent for detergent industry.the synthetic detergent and sop will have better out looking if using this agent.
2.Whitening agent for the fatric of cotton fiber,nylon,etc.Hax excellent whiten effect on artificial fiber,polyamide,vinylon,also has well whiten effect on casein fiber,amide plastic.
PROCEDURE:
Optical brightener CXT has less solubility than VBL and 31#,it can be solved with hot water and form 10% turbid solution.it should be used immediately when the solution is ready and avoid sunlight.The dosege used in detergent industry is 0.1-0.5%,in dyeing industry is 0.1-0.3%.
PACKAGE: Packed in iron bucket or cardboard bucket after being packed in plastic bag first.Net Weight per bucket is 20kg or 25kg.
TRANSPORTATION: Should avoid sunlight and carsh.
≤Should be stored in cool,dry and ventilate place,stored term shouldn't exceed 2 years.
