Study of the influence of the sizing agent on the breakage of warp threads in weaving
Abstract
One of the main objectives of weaving production is the production of high quality fabrics and the search for ways to increase the productivity of weaving machines in order to improve the economic performance and competitiveness of the enterprise. In the production conditions of RUPTE "Orsha Linenmill" weaving machines Picanol OptiMax 190 are installed for the production of a range of household fabrics from low linear density yarn, most of which are exported. To ensure the quality of pure linen fine fabrics and the production of fine yarn, long flax fibre No. 11–14 and above is required. However, due to a number of reasons, the quality and quantity of incoming domestic raw materials cannot guarantee stable technological efficiency of production preparation and weaving processes, which is provided by the uniformity of flax and flax-containing yarn and its tensile properties. The aim of the research is to reduce warp breakage in weaving by determining rational production parameters on the loom and the choice of the sizing agent in order to increase the productivity of the loom in the production of linen fabrics with low surface density. In the article the properties of wet spinning yarn of 30 tex linear density made of long linen fibre are studied, the features of Karl Mayer SMR-SP-10-1800/800 SMR-SP-10-1800/800 sizing machine and Picanol OptiMax 190 rapier weaving machine are studied, the selection of modern sizing agent was made in order to increase machine productivity and reduce warp breakage during weaving of the most elite and marketable article – linen fabric with surface density of 120 g/m2. The changes in the technology made it possible to reduce the equipment downtime by reducing the number of warp breaks from 0.95 to 0.76 breaks per 1 running meter of fabric, to increase the coefficient of utilisation and to increase the annual volume of fabrics produced.
