Abstract: The present invention teaches an improved process for preparing a population of microcapsules having a substantially uniform size distribution, especially useful for manufacture of carbonless paper. The improved process teaches use of membrane material having a pre-selected pore size in the capsule manufacture process. A core material is provided along with a receiving solution for receiving the core material. The receiving solution is a nonsolvent for the core material. The core material is passed under pressure through the membrane into a moving or turbulent receiving solution forming uniform droplets of core material dispersed in the receiving solution. Wall-forming material is added to the receiving solution for coating the core material droplets. The coating on the droplets is polymerized forming microcapsules. This novel process also lends itself to microcapsule formation in a continuous process.

Abstract: Dual shell microcapsule aggregate particles and copy materials coated therewith, such aggregate particles having inner shells surrounding chromogenic nucleus material, and outer shells encompassing multiple such inner shells to form aggregate particles thereof. The inner shells are derived from polar pre-polymer compositions. The outer shells are derived from complex colloids such as gelatin and gelatin derivatives. The outer shell material causes agglomeration of the inner shells into aggregate particles, thus increasing the sizes of the particles without increasing the sizes of the respective inner-shell microcapsules which contain the chromogenic material.

Abstract: Disclosed is a process for preparing a fibrous web. The fibrous web includes a microencapsulated material, such as a microencapsulated phase change material, adhered to the web. Preferably, the web is prepared in a melt-blowing or spun-bonding process. In the melt-blowing process, cooling water containing the microcapsules is used to cool melt blown fibers prior to collection on a collector. In the spun-bonding process, microcapsules are applied in liquid suspension or in dry form to a heated web, for instance, after the web has been calendared. The fibrous webs thus prepared have numerous uses, and are particularly suited to the manufacture of clothing.

Abstract: The present invention provides an improvement to the two, inaccurate, traditional approaches relating concentration to density. The first of these assumes that the solute is completely insoluble in the solvent; the second is based on a soluble solute. The present improved relationship is referred to as the CONCENTRATION-DENSITY MODEL. This model allows for a theoretical determination of the concentration-density relationship for a multi-component solid/liquid or liquid/liquid mixture. Included in the Concentration-Density Model is a new concept referred to as ADDITIVE VOLUME COEFFICIENT (AVC). This concept compensates for the fact that the net volume of a mixture does not always equal the sum of the volumes of each component. This improved Concentration-Density Model provides fluid-handling manufacturers with a method for accurately determining a mixture's concentration on-line with the aid of current density measurement instrumentation.
