    摘要： The present invention relates broadly to a method of image analysis for analyzing the texture of a surface, and to a saxony-type carpet having a tightly tailored surface texture characterized by this method. The method employs a model based on a second order co-occurrence matrix model which calculates a set of textural parameters for image classification. This co-occurrence matrix model examines the statistics of the spatial relationship between gray levels in a homogeneously textured image with calculated textural features which represent measures such as homogeneity and contrast. The method of the present invention uses this model to construct a set of normalized textural parameters from the textural parameters and calculates a value for the normalized textural parameters from this set, where the normalized textural parameters are related to the physical properties of the surface, such as pile lay of a carpet. The method compares the value for each of the normalized textural parameters of an unknown sample to the value for each of the corresponding normalized textural parameters for a known, or goal, sample. In one embodiment, the method compares an unknown sample of a saxony-type carpet to a goal sample of a saxony-type carpet having a tightly tailored surface texture to determine whether the unknown sample is such a carpet.

    摘要： A process for treating a ply-twisted crimped multifilament yarn. The process involves adjusting the temperature and moisture content of the yarn prior to passing the yarn through a stuffer box which is essentially free of steam. Excess hot fluid is removed from the yarn, and the yarn's temperature is adjusted to a temperature in the range of about 40.degree. to 90.degree. C. before the yarn is passed through the stuffer box. The yarns may be used for making a textured saxony-type carpets having a tightly tailored surface texture.

    摘要： An alternate twist plied yarn formed from a plurality of strands of singles yarn twisted in alternating directions in lengthwise intervals of first half-cycles of twist at a predetermined twist level followed by second half-cycles of twist at the same twist level with reversal nodes therebetween, the singles twisted yarns being ply-twisted together in alternating directions in lengthwise intervals of first half-cycles of ply-twist followed by second half-cycles of ply-twist, there being a bond formed adjacent each node wherein the first half-cycle of ply-twist is located within the bond and the second half-cycle of ply-twist originates at one end of the bond, the twist level in the singles twisted yarn is between 25% in the same direction and 60% in the opposite direction of the twist applied to the singles yarns before plying. The process for making an alternate twist plied yarn formed from a plurality of singles strands wherein the plied yarn has low residual singles twist is disclosed as well as an apparatus for forming bonded alternate twist plied yarn from a plurality of strands having a distance between twist reversal nodes defining sections of alternate twist in the yarn and having bonds in the plied yarn adjacent the reversals.
