Problems solved by technology

[0004] However, the traditional finishing methods of halamine antibacterial agents are rolling and baking, which requires high-temperature baking of fabrics, and the addition of crosslinking agents or initiators can be grafted to cotton fabrics in the form of chemical bonds, which increases the cost of raw materials
The processing process is more complex and the process conditions are harsh

Embodiment 1

[0045] React with 0.1 mol of NaOH and 0.1 mol of 5,5-dimethylhydantoin as raw materials, then add deionized water, and stir for 15 minutes to obtain a colorless and transparent solution, which is the sodium salt of 5,5-dimethylhydantoin. Then add 0.1mol of 3-chloro-1-propanol, raise the temperature to 100°C and add a magnetic stirrer to stir the solution, and react for 10h under the condition of condensation and reflux to obtain 3-(3-hydroxypropyl)-5,5 - crude product of dimethylhydantoin. The deionized water was distilled off under reduced pressure using a rotary evaporator to obtain a solid mixture. Dissolve in acetone, filter, and spin evaporate the filtrate to obtain a solid that is 3-(3-hydroxypropyl)-5,5-dimethylhydantoin. Put the 3-(3-hydroxypropyl)-5,5-dimethylhydantoin obtained in the first step into 100ml of tetrahydrofuran, and use 0.1mol of triethylamine as an acid scavenger. Under the condition of ice bath, 0.1 mol of acryloyl chloride was added dropwise and all...

Embodiment 2

[0047] React with 0.1 mol of NaOH and 0.1 mol of 5,5-dimethylhydantoin as raw materials, then add deionized water, and stir for 15 minutes to obtain a colorless and transparent solution, which is the sodium salt of 5,5-dimethylhydantoin. Then add 0.1mol of 3-chloro-1-propanol, raise the temperature to 100°C and add a magnetic stirrer to stir the solution, and react for 12h under the condition of condensation and reflux to obtain 3-(3-hydroxypropyl)-5,5 - crude product of dimethylhydantoin. The deionized water was distilled off under reduced pressure using a rotary evaporator to obtain a solid mixture. Dissolve in acetone, filter, and spin evaporate the filtrate to obtain a solid that is 3-(3-hydroxypropyl)-5,5-dimethylhydantoin. Put the 3-(3-hydroxypropyl)-5,5-dimethylhydantoin obtained in the first step into 100ml of tetrahydrofuran, and use 0.1mol of triethylamine as an acid scavenger.

Embodiment 3

[0049] React with 0.1 mol of NaOH and 0.1 mol of 5,5-dimethylhydantoin as raw materials, then add deionized water, and stir for 15 minutes to obtain a colorless and transparent solution, which is the sodium salt of 5,5-dimethylhydantoin. Then add 0.1mol of 3-chloro-1-propanol, raise the temperature and add a magnetic stirrer to stir the solution, and react for 15 hours at 95°C to obtain 3-(3-hydroxypropyl)-5,5-dimethyl Crude product of Ghenyne. The deionized water was distilled off under reduced pressure using a rotary evaporator to obtain a solid mixture. Dissolve in acetone, filter, and spin evaporate the filtrate to obtain a solid that is 3-(3-hydroxypropyl)-5,5-dimethylhydantoin. Put the 3-(3-hydroxypropyl)-5,5-dimethylhydantoin obtained in the first step into 100ml of tetrahydrofuran, and use 0.1mol of triethylamine as an acid scavenger. Under the condition of ice bath, 0.1 mol of acryloyl chloride was added dropwise and allowed to react for 1 h under the condition of i...

Abstract

The applicant provides a halamine double bond hydantoin antibacterial agent and its preparation and application method. First add equimolar NaOH and 5,5 dimethylhydantoin into the flask, then add deionized water, stir until it is colorless and transparent, then add the same mole of 3-chloro-1-propanol, and heat up to 100°C. Under the condition of condensation and reflux, react for 10-15h; put the obtained product into a flask, use tetrahydrofuran as a solvent, add the same mole of triethylamine as an acid scavenger, and add an equimolar amount of acryloyl chloride dropwise under the condition of an ice bath , react for 1h; react at room temperature for another 20‑24h, thus obtaining 3‑(3‑propyl acrylate)‑5,5‑dimethylhydantoin. The method is simple and efficient, does not need to use an initiator or a crosslinking agent, has mild process conditions, does not require high temperature, and saves energy; uses high-energy electron beam energy to initiate, reduces the pollution of industrial waste liquid, has a significant bactericidal effect, and has a good application prospect.

Description

technical field [0001] The invention relates to the production technical field of functional textiles, in particular to a method for synthesizing haloamine double-bond hydantoin and an electron beam irradiation preparation method of haloamine double-bond hydantoin antibacterial cotton fabric. Background technique [0002] Cotton fiber is a kind of natural fiber with good wearing performance. It has the advantages of moisture absorption and breathability, and is widely used in daily life. But at the same time, cotton fiber is also a breeding ground for bacteria. Under certain humidity and temperature, bacteria can multiply quickly, which not only damages the fiber itself, but also easily spreads diseases, posing a huge threat to human health. Especially in medical places and the food industry, it is particularly important to prevent the growth of bacteria. Therefore, the research of antibacterial cotton fabric is particularly important. [0003] Antibacterial agents are div...
