We present dust color temperature, dust mass and inclination angle of four far infrared loops namely G007+18, G143+07, G214-01 and G323-02 which are found to be located within 1o from pulsars PSR J1720-1633, PSR J0406+6138, PSR J0652-0142 and PSR J1535-5848, respectively. These low latitude loops (l<20o) are believed to be formed because high pressure events occurred in the past (e.g., supernova explosion). The dust color temperature of the core region is found to lie in the range 19.4±1.2−25.3±1.7K, whereas the range increased to 33±2−47±3K for the outer region. The dust color and dust mass distribution maps show that the low temperature region has greater density as expected. The core region of one loop is found to be edge-on (i > 70o) whereas the larger structure is nearly face-on (i < 70o).
