Abstract: A device for detecting a mixture ratio of two components of a textile fabric contains a radiation source for transmitting electromagnetic radiation in a spectral band in the direction of the textile fiber structure, a radiation sensor for receiving at least a part of the electromagnetic radiation, and a spectral filter with spectral properties in the spectral band for filtering at least one part of the electromagnetic radiation. The transmittance of the spectral filter in the spectral band has at least one local maximum and at least one local minimum. The spectral properties of the spectral filter in the spectral band are adapted to the spectral properties of the radiation source and each of the two components such that a radiation intensity received by the radiation sensor is a monotonous function of the mixture ratio of the two components. The device is simple in design and allows the use of spatially resolving imaging radiation sensors.

Abstract: A method and system for inspection of an item, and a use thereof, are presented. The method comprises acquiring a plurality of projection images of an item at a plurality of projection angles for performing a tomographic reconstruction of the item. A plurality of objects are detected in the tomographic reconstruction and each object has a generic shape described by a parametric three-dimensional numerical model. Said detection comprises determining initial estimates of position and/or orientation of each object and at least one geometrical parameter of the three-dimensional model for each object. The initial estimates are iteratively refining by using a projection-matching approach, in which forward projection images are simulated for the objects according to operating parameters of the radiation imaging device and a difference metric between acquired projection images and simulated forward projection images is reduced at each iteration step.

Abstract: An apparatus (100) for measuring not only the reflected radiation but also the fluorescence emission of a textile sample (106), which includes a presentation subsystem (102) having a viewing window (108). A radiation subsystem (114) has a tunable radiation source (120) for directing a desired radiation (122) having a wavelength range and an intensity through the viewing window (108) toward the sample (106), and thereby causing the sample (106) to produce a fluorescence (124). A sensing subsystem (126) has an imager (130) for capturing the reflected radiation and fluorescence (124) in an array of pixels. A control subsystem (132) has a processor (136) for controlling the presentation subsystem (102), the radiation subsystem (114), and the sensing subsystem (126), and creates a reflected radiation and fluorescence image containing both spectral information and spatial information in regard to the reflected radiation and fluorescence (124) of the sample (106).

Abstract: Modeling cross-sections of yarn may include receiving yarn simulation input comprising a descriptive model of a general curvature followed by the yarn, providing a plurality of fibers distributed radially from the center of a ply, setting a base position based on parameters, applying a strain model to simulate the effect of stretch forces applied to the yarn, and outputting a yarn model indicating position and directionality of fibers in the yarn. The technology also relates to real-time modeling of a garment comprising a fabric. For instance, real-time modeling of a garment may include providing an input associated with one or more parameters of the fabric, receiving frames of a computer simulated garment, the computer simulated garment including a simulation of the fabric, the fabric simulation including yarns simulated based on a yarn model.

Abstract: A method evaluating a strength of a textile for use in articles of clothing representative of normal wear and tear and comprising testing samples including the textile treated with an application of polyethylene, the untreated textile, and/or the textile being washed and dried one or more times; and/or where the textile has been conditioned. Each sample tested is weighed prior to and after abrasion resistance testing is conducted on each sample. The samples are each abraded with an abrasion resistance testing machine that has been modified with ISO test heads and an abrasive surface having a plurality of abrasion layers thereon. A number of rubs of abrasion between the abrasive surface and the test sample is pre-selected such that the test is run until the selected number of rubs have been completed. A bursting strength test can be further conducted on abraded areas of the testing samples.
