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: dissolving the dispersed ultraviolet absorber Rayosan P in water to prepare a finishing solution, then adding the reactive ultraviolet absorber Rayosan C to the above finishing solution, and then adding Sodium chloride, when the temperature of the finishing solution is 30°C, put the fabric of the polyester umbrella into the finishing solution, the dyeing bath ratio is 1:50, then raise the temperature to 40°C at a heating rate of 0.5°C / min, and add sodium carbonate to the finishing solution , keep warm for 20 minutes, then raise the temperature to 130 ℃ at a heating rate of 2 ℃ / min, keep warm for 30 minutes, and wash and dry fully after the heat preservation is completed. The finishing liquid prescription 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: dissolving the dispersed ultraviolet absorber Rayosan P in water to prepare a finishing solution, then adding the reactive ultraviolet absorber Rayosan C to the above finishing solution, and then adding Sodium chloride, when the temperature of the finishing solution is 30°C, put the fabric of the polyester umbrella into the finishing solution, the dyeing bath ratio is 1:20, then raise the temperature to 40°C at a rate of 1°C / min, and add sodium carbonate to the finishing solution , keep warm for 30 minutes, then raise the temperature to 120 ℃ at a heating rate of 1 ℃ / min, keep warm for 40 minutes, and wash and dry fully after the heat preservation is completed. The finishing liquid prescription 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: dissolving the dispersed ultraviolet absorber Rayosan P in water to prepare a finishing solution, then adding the reactive ultraviolet absorber Rayosan C to the above finishing solution, and then adding Sodium chloride, when the temperature of the finishing solution is 30°C, put nylon core-spun silk stockings into the finishing solution, the dyeing bath ratio is 1:50, then raise the temperature to 40°C at a heating rate of 0.5°C / min, add sodium carbonate to the finishing solution, Keep warm for 40 minutes, then raise the temperature to 100°C at a heating rate of 1°C / min, keep warm for 30 minutes, and wash and dry fully after the heat preservation is over. The finishing liquid prescription 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 a method of anti-ultraviolet finishing for polyester umbrella fabrics, nylon core-spun stockings and nylon swimwear fabrics by using a reactive ultraviolet absorber and a dispersed ultraviolet absorber, with simple process flow and reduced energy consumption , and the obtained product has excellent anti-ultraviolet performance and good washability. Background technique [0002] Polyester-nylon fabrics have higher strength and can be woven into tighter fabrics. They are currently one of the main raw materials for umbrella fabrics. The sunny umbrella is not only suitable for use as a sun umbrella in sunny days to prevent ultraviolet radiation, but also suitable for use as an umbrella in 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. But the main problem that exists at pr...
