FABRIC IMPREGNATED WITH FUNCTIONAL SUBSTANCES FOR CONTROLLED RELEASE |
| 摘要 |
<p>Intersticed materials, including woven and nonwoven fabrics, open-cellular materials and the like, are impregnated with functional substances by incorporating the substances in microscopic porous particles in which the pores form an interconnected network open to the particle exterior, and placing these impregnated particles in the interstices of the materials. The functional substances thus impart useful properties to the material in a controlled release manner.</p> |
