Embodiment Construction

[0034] figure 1A possible index protocol for a textile structure such as a yarn is illustrated in the form of a predetermined quality curve 103 . A specific flaw parameter such as flaw size (eg diameter, or a product having a diameter and length) is input along the horizontal axis 101 and the frequency of each flaw parameter such as the number of flaws is entered along the vertical axis 102 . The individual yarns are represented by measurement points. The first yarn 104 represented by its measurement point lying above the curve 103 is considered to be non-compliant according to the defect parameter. The quality of the yarn can be increased to quality 114 when using a device such as a yarn clearer that can reduce defects. As indicated by arrow 124, the parameterization of the device is correlated, thereby removing a higher number of artifacts. However, this comes at the expense of productivity (the speed at which the yarn travels).

Abstract

The invention discloses a method for optimizing the manufacturing process of quality, capacity and/or profitability in a textile plant is applied when raw material is processed in the manufacturing process in several processing steps into intermediate products and an end product is produced. Parameters (301, 303, 312, 393) of the raw material, the intermediate products and/or the end product are measured in at least two different processing steps, stored in a database (300) and linked in an index file (3002). Thus the employed qualities of a lot are as close as possible to the quality of a lot which can also be designated as necessary quality of a lot in order to offer the yarn quality provided for a delivery agreement.

Description

Background technique [0001] The invention relates to a method for monitoring a production process in a textile mill, such as a spinning mill, a weaving mill or an embroidery mill, as stated in the preamble of the first claim. [0002] current technology [0003] The various raw materials are processed in several processing steps in the spinning mill via intermediate products into yarn as the final product. The raw material goes through various workstations such as cleaning, opening, cleaning, blending, carding, combing, drafting, slubbing, worsted spinning and finally winding and winding. Machines equipped with sensors are used in most steps. The sensor signals are used to control the process, and / or monitor the quality of intermediate and final products produced. [0004] In DE-41'13'384 C2 a method and a system for quality monitoring in spinning mills are given, in which data are collected for a batch of products in a single instance and are linked to the processing of th...
