Embodiment 5: technique is on the impact of hydrophobic effect
(1) esters of acrylic acid concentration
Low surface compound acrylic ester monomer consumption is lower than 20%, and after adopting electron beam irradiation, the experiment display water droplet that drips infiltrated COTTON FABRIC in 1 minute, was evaluated as without hydrophobic effect.Because content of monomer is less, effective low-surface energy substance (alkane chain) can not be formed at fabric face after radiation and cover.Acrylic ester monomer consumption, higher than 80%, exceedes its solubility in a solvent, dissolving of must heating, and makes that production process is complicated, cost improves.
(2) irradiation dose
Irradiation dose is too low, such as 22KGy, and after irradiation arranges, the experiment display water droplet that drips infiltrated COTTON FABRIC in 1 minute, was evaluated as without hydrophobic effect.Because irradiation energy is not enough to the graft polymerization reaction of initiating methacrylates compounds and COTTON FABRIC, cause without low-surface energy substance covering fabric, therefore without hydrophobic performance.Irradiation dose is too high, such as 80KGy, although irradiation arranges rear fabric have good hydrophobic effect, fabric turns to be yellow, tendering phenomenon is serious.This is because too high irradiation can cause the fracture of fiber macromolecular chain, fabric is caused to sustain damage.
Although the present invention with preferred embodiment openly as above; but it is also not used to limit the present invention, any person skilled in the art, without departing from the spirit and scope of the present invention; all can do various changes and modification, what therefore protection scope of the present invention should define with claims is as the criterion.
