Automation in Measurement of Inverse Creep in Textile Yarns

From decades Creep has been known and studied for textile materials. In comparison, a newly observed phenomenon of inverse creep seems not to have received much attention. A new instrument has been fabricated to measure creep and inverse creep in textile materials particularly yarns. Creep and Inverse creep measurements of few of the textile yarns like nylon multifilament yarn, Polyester multifilament yarn, Cotton and wool yarn at different levels of stress have been studied, using the new instrument along with Transreceiver, embedded system and Personal computer the automation is achieved and results are reported in the present paper.

Measurements of Inverse Creep in Polyester Multifilament Yarns

Creep and Inverse creep are the important fundamental properties of textile materials. These properties determine the relaxation behaviour of the product. We have designed and fabricated an instrument which can measure the creep and inverse creep. The instrument consists of a Trans - Receiver unit interfaced with Embedded System along with the Personal Computer. Existing technique for measuring inverse creep does not measure the instantaneous extension or contraction. The newly fabricated instrument, can measure the instantaneous extension and contraction of the yarn up to an accuracy of 0.02%. This can be measured after every 500 µs. The position of the yarn, which is to be hanged, is vertical. The ‘Electronic Timer Unit’, replaces a meter scale. Set up is improved by using electronic utilities. The capability is enhanced to next level of time and distance resolutions. Automation enables to have flexibility of time from microseconds to minutes. Data is stored in different text files. Different samples of Polyester multifilament yarn were used in the experiment. The length and the load were altered. Change in stress lead to instantaneous extension or contraction followed by creep or inverse creep. This can sensed by the sensor and further stored in the memory of the Computer. The percentage creep and inverse creep were measured and have been reported in this present paper

Deformation of Chemically Crosslinked Polyethylene Foam. 1. Thermal Deformation of Polyethylene Foam

An investigation was made of the influence of the cellular structure on the coefficient of linear thermal deformation and inverse creep of chemically crosslinked polyethylene foam PPE-3M. The dependence of deformability on the nature of the force effect and on the temperature when exposed to the force effect at the stage of production of chemically crosslinked polyethylene foam was established.
