Problems solved by technology

[0004] The technical problem to be solved by the present invention: Aiming at the problems of poor anti-ultraviolet performance and short anti-ultraviolet period of existing fabrics, the present invention provides a preparation method of cinnamoylated modified fabrics, which have anti-ultraviolet properties by grafting on the surface of the fabrics. The cinnamoyl group with UV performance makes the fabric have better UV protection performance and UV protection cycle, reducing the risk of short UV protection cycle of fabrics caused by separate treatment of finishing agents

Embodiment 1

[0020] A preparation method of cinnamoylated modified fabric fabric, comprising the following steps:

[0021] (1) Immerse the fabric in 7.5% sodium hydroxide, potassium hydroxide, sodium bicarbonate solution, stir at 34°C for 45 minutes at a speed of 400r / min, dry the lye, and then dry the fabric Wash 3-5 times with clean water and dry the fabric for later use;

[0022] (2) Immerse the dried fabric in step (1) in 45% acrylic acid aqueous solution, in which the acrylic acid solution contains 4% 2-sec-butyl-4,6-dinitrophenol, and slowly raise the temperature of the system to 35°C, keep the temperature and react with stirring at a speed of 200-500r / min for 1.5h to obtain a carboxyl-modified fabric;

[0023] (3) Dissolve the PEG 750 modified with amino groups at both ends with 0.01M pH7.4 PBS buffer to prepare a PEG solution with a mass fraction of 23%; dissolve carbodiimide into 0.01M pH7.4 PBS buffer solution to make the mass fraction 8%, and then immerse the carboxy-modified ...

Embodiment 2

[0027] A preparation method of cinnamoylated modified fabric fabric, comprising the following steps:

[0028] (1) Immerse the fabric in 5% sodium hydroxide, potassium hydroxide, sodium bicarbonate solution, stir at 28°C for 30 minutes at a speed of 300r / min, dry the lye, and then dry the fabric Wash 3-5 times with clean water and dry the fabric for later use;

[0029] (2) Immerse the dried fabric in step (1) in 30% acrylic acid aqueous solution, in which the acrylic acid solution contains 3% 2-sec-butyl-4,6-dinitrophenol, and slowly raise the temperature of the system to 28°C, keep this temperature and react with stirring at a speed of 200r / min for 1h to obtain a carboxyl-modified fabric;

[0030] (3) Dissolve PEG 550 modified with amino groups at both ends with 0.01M PBS buffer at pH7.4 to prepare a PEG solution with a mass fraction of 15%; dissolve carbodiimide into 0.01M PBS buffer with pH7.4 solution to make the mass fraction 5%, and then immerse the carboxy-modified fab...

Embodiment 3

[0034] A preparation method of cinnamoylated modified fabric fabric, comprising the following steps:

[0035](1) Immerse the fabric fabric in 6% sodium hydroxide, potassium hydroxide, sodium bicarbonate solution, stir at 30°C for 40 minutes at a speed of 350r / min, dry the lye, and then dry the fabric Wash 3-5 times with clean water and dry the fabric for later use;

[0036] (2) Immerse the dried fabric in step (1) in 30-60% acrylic acid aqueous solution, wherein the acrylic acid solution contains 3-5% 2-sec-butyl-4,6-dinitrophenol, and the system The temperature was slowly raised to 3°C, and the temperature was maintained to react at a speed of 300r / min for 1.2h to obtain a carboxyl-modified fabric;

[0037] (3) Dissolve PEG 1000 modified with amino groups at both ends with 0.01M pH7.4 PBS buffer to prepare a PEG solution with a mass fraction of 20%; dissolve carbodiimide into 0.01M pH7.4 PBS buffer solution to make the mass fraction 6%, then immerse the carboxy-modified fab...

Abstract

The invention provides a preparation method of cinnamoyl modified fabric, comprising the following steps: treating fabric with alkali lye; preparing carboxyl modified fabric by using acrylic acid; preparing amino-modified fabric through PEG which is amino-modified at two ends; grafting cinnamoyl chloride to the surface of the amino-modified fabric to obtain cinnamoyl modified fabric; and putting the cinnamoyl modified fabric into an ethanol solution containing dihexadecyldimethylammonium bromide, polydimethylsiloxane diquaternary ammonium salt, amino silicon oil, methyl salicylate and polyhexamethylene biguanidine hydrochloride so as to prepare the fabric finished product. It shows through test results that the prepared fabric has good anti-ultraviolet capability and the retention time ofanti-ultraviolet period is long. Thus, the fabric has higher use value when used as anti-ultraviolet fabric.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a preparation method of a cinnamoylated modified fabric. Background technique [0002] Ultraviolet light refers to a continuous spectrum with a wavelength range of 400-100nm. Appropriate amount of ultraviolet light has the effect of sterilization and disinfection. At the same time, it can also promote the production of vitamin D, which is helpful for the absorption of calcium in the human body and promotes the healthy development of bones. However, excessive ultraviolet rays will not only cause sunburn and aging of human skin, but also produce melanin and photopigmentation. In more serious cases, it can induce cancer and endanger human health, and when it is strong, the skin is easily sunburned, leading to skin cancer, cataracts, etc., and biological growth. Therefore, preventing ultraviolet rays from harming the human body is more and more valued by people, and the...
