Estimating the term…
This invention relates to a microcapsule having a particle diameter of 2.about.300 .mu.m and comprising a substance acting to improve physiological conditions of human skin, for example, substances exhibiting such effects as skin whitening, aging preventive, humidity preservable, itch suppressive, pain-killing, or antiphlogistic ones, and/or aromatic agents contained within the filmy coating of synthetic high molecular substance. The microcapsule is not broken when making, processing, or laundering the textile structure, but is gradually broken when the textile structure is put on the human body, used for another purpose, or subjected to intentional application of friction or pressure thereto, and sustainedly releases acting substances contained therein. Treatment liquids comprising these microcapsules and binder, preferably containing a spraying agent, adapt the microcapsules to tightly adhere to textile structures such as stockings underwear, and bedclothes, thereby providing a textile structure to exhibit the aforesaid effects.
A textile structure having microcapsules adhered thereto by a binder, said microcapsules having a particle diameter in the range of 2.about.40 .mu.m and a wall membrane comprising a synthetic high molecular material and encapsulating a substance for improving physiological conditions of the human skin, said substance selected from the group consisting of ascorbic acids, tocopherols, seaweed extracts, antipruritics and analgesics, said microcapsules and binder being in a weight ratio in the range of 10:1.about.1:5, the total amount of both the microcapsules and binder being 0.3.about.15% based on the weight of the portions of the fibers to which the microcapsules and binder are adhered to.
A textile sheet material, wherein a first textile fabric, having microcapsules adhered thereto by a binder, is laminated with a second textile fabric or sheet, said microcapsules having a particle diameter in the range of 2.about.40 .mu.m and a wall membrane comprising a synthetic high molecular material and encapsulating a substance for improving physiological conditions of the human skin, said substance being selected from the group consisting of ascorbic acids, tocopherols, seaweed extracts, antipruritics and analgesics.
