SOFTWARE APPLICATION USED AS TEACHING TOOL FOR THE DESIGN OF FIBRE BLENDS Authors: PIROI Cristina, CRISTIAN Irina Volume 3 | DOI: 10.12753/2066-026X-16-258 | Pages: 541-546 | Download PDF | Abstract
In spinning mills, the optimum correlation between the raw material properties, the yarn's characteristics and the manufacturing technology, is a key point for the production of good quality yarns. Beyond of its significant influence on the yarn characteristics, the raw material determines also the yarns' cost, representing up to 80% of it. Using the blending technique, in which fibres with different properties are combined in order to obtain mixture with average characteristics, it is possible valorising all types of fibres and producing yarns with desired characteristics. In this regard, the yarn designer has to choose the appropriate fibres and setting the right values for blend ratios, in order to obtain the best correlation between the fibres blend properties and the yarn characteristics.
The paper presents a software application used as teaching tool for designing the fibre blends. The PFirL software gathers all the information and provides all the tools required for design of the fibre blends in wool spinning mill. It has a modular structure that includes independent procedures; these can be performed individually or in the logical order imposed by the algorithms underlying the program. The software is used to teach the students the principles of rational fibre blend design and to train them in accordance with the requirements of engineering profession. This tool enables the creation and verification of fibre blends in accordance with the yarns destination, mixture composition and manufacturing technology. It evaluates the spinnability of the designed blends and offers useful information for predicting their behaviour during processing, as well about the yarns' characteristics. The software was created with Microsoft Visual Basic and Visual C++ and runs in a Windows environment. | Keywords
