Influences of Temperature on the Performance of Polypropylene Woven Geotextiles

Abstract:

Article Preview

Needle punching geotextile composites are composed of polypropylene woven fabrics and nonwovens, which has lower strength than that of the original woven fabrics because of the damaging effects by needles during the bonding process. In order to compensate for this shortage, a new geotextile composite was developed using adhesive as bonding media, temperature for controlling adhesive bonding effects. So temperature is the most important factor influencing the composites. With the purpose of researching temperature effects on the performance of polypropylene woven fabrics (single layer of the geotextile composite), a series of tests were carried out and then analyzed. The results show that with the increment of temperature, the shrinkage rate of polypropylene woven fabrics increased continuously. On the other hand, the strength firstly rise with the temperature and then decreased when temperature is over 130°C. Conclusions got in the paper are good references for the development of a new kind of water-insoluble adhesive and adhesive bonded nonwoven geotextile composite.
