A method evaluates a fiber product and includes washing at least one fiber product by a washing machine and washing conditions defined in ISO 6330 (2012), collecting fiber fragments discharged from a wastewater outlet of the washing machine by a filter with a sieve opening of 5 to 20 μm, and measuring a weight of the fiber fragments.

The current invention concerns determining a fiber composition of a textile sample. The sample is irradiated with near infrared (NIR) light. Reflected NIR light from the sample is captured. A vector of spectral values is determined based on the captured light. The vector is input to a deep neural network (DNN). The DNN comprises a sequence of layers of nodes, in particular an input layer, at least two intermediate layers, and an output layer. The nodes of successive layers of the sequence are interconnected via weighted edges. The DNN outputs for each of a plurality of fiber material types a numerical relative composition amount.

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 computer-implemented method for determining a hygiene condition of an interior space is described. The method has the steps of: a) obtaining relative abundance of at least one bacterium of human health concern in an interior space; b) generating a Microbial Index of Interior Space (“Microbial Index”) for the interior space based on the relative abundance; and c) displaying an output indicative of the Microbial Index for determining a hygiene condition of the interior space. The Microbial Index is characterized by a function of the relative abundance of the at least one bacterium of human health concern defined by F(Σ.sub.i=1.sup.NP.sub.i), wherein N: Number of bacteria of human health concern identified in a microbial community in the interior space; P: Relative abundance of i-th bacteria of human health concern in the microbial community.

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.

A system and method for characterization of patterns marked on a fabric. The system includes a light source generating a light beam to impinge on a fabric; an optical arrangement including a parabolic mirror with a hole and an optical device, directing said light beam towards the fabric; a wavelength division unit; a light detection unit; and a computing device. The optical device changes and orients the direction of the light beam towards the fabric providing a scan of an area of the fabric, line-by-line, and redirects scattered light towards the light detection unit. The wavelength division unit separates the scattered light into spectral bands or colors and the computing device characterizes a pattern marked on the fabric by executing an algorithm that analyzes electrical voltage signals and that computes a quality measure of said marked pattern.
