Problems solved by technology

[0006] The object of the present invention is to aim at the disadvantages of the poor rain resistance after the anti-ultraviolet finishing of polyester brocade umbrella fabrics, nylon core-spun stockings and nylon swimwear fabrics, and use the same bath of reactive ultraviolet absorber and dispersive ultraviolet absorber to treat polyester brocade clear Umbrella fabrics, nylon core-spun stockings and nylon swimwear fabrics are subjected to anti-ultraviolet finishing. This method uses the characteristics of two kinds of ultraviolet absorbers to make the amino groups of nylon and reactive ultraviolet absorbers covalently bonded, so that nylon or polyester can be combined with dispersed ultraviolet absorbers. Hydrogen bond and van der Waals combination occur in the absorbent, the process used is simple, the energy and water consumption is small, and it also avoids the use of anti-ultraviolet polyester nylon umbrella fabrics, nylon core-spun stockings and Disadvantages of expensive nylon swimwear fabrics

Embodiment 1

[0017] An anti-ultraviolet finishing method. The finishing process is as follows: Dissolve the dispersed ultraviolet absorber Rayosan P in water to prepare a finishing solution, then add the reactive ultraviolet absorber Rayosan C to the finishing solution, and then add it to the finishing solution Sodium chloride, when the temperature of the finishing solution is 30℃, put the polyester nylon umbrella fabric into the finishing solution, the bath ratio is 1:50, and then heat up to 40℃ at a heating rate of 0.5℃ / min, and add sodium carbonate to the finishing solution. Keep the temperature for 20 minutes, then heat up to 130°C at a heating rate of 2°C / min, keep the temperature for 30 minutes, wash and dry thoroughly after the temperature is over. The formulation of the finishing solution is as follows: dispersive UV absorber Rayosan P 5% o.m.f, reactive UV absorber Rayosan C 2% o.m.f, sodium chloride 40g / L, sodium carbonate 0.5g / L.

Embodiment 2

[0019] An anti-ultraviolet finishing method. The finishing process is as follows: Dissolve the dispersed ultraviolet absorber Rayosan P in water to prepare a finishing solution, then add the reactive ultraviolet absorber Rayosan C to the finishing solution, and then add it to the finishing solution Sodium chloride, when the temperature of the finishing solution is 30°C, put the polyester nylon umbrella fabric into the finishing solution with a bath ratio of 1:20, and then heat up to 40°C at a heating rate of 1°C / min. Add sodium carbonate to the finishing solution. Keep the temperature for 30 minutes, then heat up to 120°C at a heating rate of 1°C / min, keep the temperature for 40 minutes, and wash and dry thoroughly after the heat preservation. The formulation of the finishing solution is as follows: dispersive UV absorber Rayosan P 8% o.m.f, reactive UV absorber Rayosan C 4% o.m.f, sodium chloride 50g / L, sodium carbonate 1.5g / L.

Embodiment 3

[0021] An anti-ultraviolet finishing method. The finishing process is as follows: Dissolve the dispersed ultraviolet absorber Rayosan P in water to prepare a finishing solution, then add the reactive ultraviolet absorber Rayosan C to the finishing solution, and then add it to the finishing solution Sodium chloride, when the temperature of the finishing solution is 30℃, put the nylon core-spun stockings into the finishing solution with a bath ratio of 1:50, and then heat up to 40℃ at a heating rate of 0.5℃ / min. Add sodium carbonate to the finishing solution to keep warm After 40 minutes, the temperature is raised to 100°C at a heating rate of 1°C / min, and the temperature is kept for 30 minutes. After the temperature is finished, it is fully washed and dried. The formulation of the finishing solution is as follows: dispersive UV absorber Rayosan P 5% o.m.f, reactive UV absorber Rayosan C 5% o.m.f, sodium chloride 50g / L, sodium carbonate 0.5g / L.

Abstract

The invention discloses an anti-ultraviolet finishing method, wherein a dispersive type ultraviolet absorbent is dissolved into water and prepared into a finishing liquid and the concentration of the dispersive type ultraviolet absorbent is 1-10% o.m.f; a reactive type ultraviolet absorbent is added to the finishing liquid and the concentration of the reactive type ultraviolet absorbent is 1-10% o.m.f; next, 10-80 g / L of sodium chloride is added to the finishing liquid; when the temperature of the finishing liquid is 30 DEG C, fabrics are put in the finishing liquid at a dyeing bath ratio of 1; (10-100); and then the temperature is increased to the range of 40-80 DEG C at a temperature rise rate of 0.5-2 DEG C / min; 0.5-2 g / L of sodium carbonate is added to the finishing liquid; heat is preserved for 20-40 min; furthermore, the temperature is increased to the range of 90-130 DEG C at the temperature rise rate of 0.5-2 DEG C / min and the heat is preserved for 20-60 min; after heat preservation is finished, thorough water washing and drying are performed. The technical scheme of the anti-ultraviolet finishing method is simple in process and convenient for operation, and has no special requirement for equipment; as a result, large-scale production can be realized just by using the conventional dyeing equipment.

Description

Technical field [0001] The invention belongs to the technical field of dyeing and finishing, and relates to an anti-ultraviolet finishing of polyester nylon umbrella fabrics, nylon core-spun silk stockings and nylon swimwear fabrics using reactive ultraviolet absorbers and dispersed ultraviolet absorbers. The process is simple and energy consumption is reduced. , And the prepared product has superior UV resistance and good washing resistance. Background technique [0002] Polyester-nylon fabrics have higher strength and can be woven into tighter fabrics, and are currently one of the main raw materials for umbrella fabrics. The sunny umbrella is suitable for use as a sun umbrella to prevent ultraviolet radiation on sunny days, and also suitable for use as an umbrella on rainy days. It can achieve the dual-purpose function of an umbrella. The product is deeply loved by consumers and the market demand is very strong. However, the main problem at present is that this type of umbrell...
