Synthesis, characterization and application of reactive UV absorbers for enhancing UV protective properties of cotton fabric

TWO colourless reactive UV absorbers 1 and 2 were synthesized by the condensation reaction of both 2,4,6-trichlorotriazine and sulfanilinic acid with 4-aminobenzophenone and ethyl 4-aminobenzoate, respectively. The structures of UV absorbers 1 and 2 were confirmed by IR, NMR (1H and 13C), and elemental analysis. The synthesized reactive UV absorbers were applied to cotton fabric using pad-dry method in comparison with both exhaustion and microwave methods. The results showed that excellent ultraviolet protection factor (UPF) values were achieved on sodium hydroxide-treated cotton fabric using pad-dry method. The optimal conditions using pad-dry method, such as drying temperature, drying time and UV absorber concentration were discussed. It was found that the highest values of UPF and whiteness using reactive UV absorbers 1 and 2 especially after washing can be obtained in the conditions of 80 °C drying temperature, 3 hours drying time and 15 g/l UV absorber concentration. The new reactive UV absorber 1 achieved excellent UPF value (58.2) compared to UV absorber 2 which exhibited poor UPF value (10.5) at the same conditions.

Cotton reaction type phosphorus-nitrogen-sulfur synergistic flame retardant preparation method

The invention relates to a cotton reaction type phosphorus-nitrogen-sulfur synergistic flame retardant preparation method. Dichloro-cyanuro sodium sulfanilate salt is added into a three-mouth flask, an appropriate amount of distilled water is poured into the three-mouth flask to serve as a solvent, the three-mouth flask is fixed into a warm water bath of a heat collection type magnetic stirrer byan iron support after uniform stirring, dimethyl hydroxy methylphosphonate water solution is dropwise added into the three-mouth flask, continuous stirring reaction is performed under a certain temperature and pH (potential of hydrogen) condition for 4 hours, and products are dried by condensation and further separated and purified to obtain reaction type phosphorus-nitrogen-sulfur synergistic flame retardants. The reaction type phosphorus-nitrogen-sulfur synergistic flame retardants can be applied to functional finishing of pure cotton fabrics, the cotton fabrics can achieve excellent flame resistance, and the flame retardants are novel functional additives.

Liquid fluorescent whitener and preparation method thereof

The invention relates to a liquid fluorescent whitener and a preparation method thereof, and belongs to the technical field of special assistants for printing, dyeing and papermaking. A technical problem to be solved is providing the liquid fluorescent whitener and the preparation method thereof. The effective component of the fluorescent whitener is 4,4'-bis[(4-anilino-6-Ramino acid)-1,3,5-triazinyl-2-yl)amino]stilbene-2,2'-tetrasulfonic acid tetrasodium salt, wherein R is a phenyl ring-containing amino acid group. The preparation method comprises the following steps: mixing 4,4'-diaminostilbene-2,2'-disulfonic acid with a NaOH solution to prepare a sodium 4,4'-diaminostilbene-2,2'-disulfonate solution product I, and mixing amino acids with the NaOH solution to prepare an amino acid sodium salt; adding an emulsifier, concentrated hydrochloric acid, cyanuric chloride and sodium sulfanilate to ice water, and reacting to generate a product II; adding the product I to the product II to generate a product III; and adding the amino acid sodium salt to the product III to obtain a crude whitener IV, carrying out pumping filtration, and carrying out desalting concentration to obtain the liquid fluorescent whitener.
