Abstract: A process for the microencapsulation of phase transitional paraffin compounds is described. Polypropylene glycols with the average molecule weight over 400 were used as the surface tension modifiers for emulsifying the paraffin compounds. Polyisocyanates capable of being dissolved in the phase change materials were employed to promote the deposition of melamine, partially methylolated melamine and the precondensate of melamine-formaldehyde onto the hydrophobic droplets for the microencapsulation. The prepared emulsion of microencapsulated phase change materials was successfully coated on textile fabrics and the coated products showed improved thermal regulation function.

Abstract: A system for analyzing fabric surface appearance includes a feed mechanism for running a fabric over a crest including a frame for holding the fabric bent to form a crest, an image capturing device for capturing profile images of the fabric surface at the crest, and a computer system for manipulating the images. The computer system produces a three-dimensional representation of the fabric surface and identifies characteristics in the three-dimensional representation. The information is compared to reference data to identify a grade for the fabric.

Abstract: A system for analysing fabric surface appearance includes a feed mechanism for running a fabric over a crest including, a frame for holding the fabric bent to form a crest, an image capturing device to capture profile images of the fabric surface at the crest, and a computer system for manipulate the images. The computer system produces a three-dimensional representation of the fabric surface and identifies prominent characteristics in the three-dimensional representation. The information is compared to reference data to identify a grade for the fabric.

Abstract: A series of paraffin compounds, the phase change materials (PCMs), were microencapsulated in an interfacial polymerization process to form the double-shell microcapsules with relatively low shell permeability. The inner shell is formed through the reaction between polypropylene glycols and bifunctional polyisocyanates and the outer through the reaction between bifunctional polyisocyanates and polyamines added in the continuous aqueous phase. The so prepared microencapsulated paraffin compounds emulsion can be used as the medium for temperature management in many fields.

Abstract: Visual thermal functional textile clothing designs are created using a programmed computer and advanced computing techniques. The computer is supplied with information from a number of databases relating to human body properties and relating to textile material characteristics. The method is used to generate functional designs that are visually displayed for use by a textile designer or engineer.

Abstract: a scanner repeatability error determining apparatus for use with a line scanning apparatus which includes a galvanometer responsive to a complex signal having ramp signal and compensation signal components for driving a line scan mirror. The compensation signal is a function of variations in velocity of the line scan mirror from a desired velocity. The apparatus includes circuitry for defining a predetermined range for the compensation signal and when such compensation signal is outside of this range produces an indication that there is a repeatability error.
