Smart Safe Dryer for Handloom with Controlled Humidity, Temperature and Airflow

Abstract

Handloom weaving involves repeated wetting of yarn during saree production to maintain stiffness and alignment. However, the subsequent drying process is typically performed using natural air or handheld devices, leading to uneven moisture removal, increased drying time, and potential fabric damage. This work proposes a compact and safe drying assistance system designed specifically for handloom environments. The system utilizes controlled airflow generated by a cooling fan combined with a low-temperature Positive Temperature Coefficient (PTC) heating element to enhance evaporation without exceeding safe thermal limits for silk and cotton fabrics. Temperature and humidity sensors continuously monitor the fabric microenvironment, enabling automatic cut-off once the desired dryness threshold is achieved. The prototype demonstrates uniform drying, reduced manual effort, and improved operational efficiency compared to traditional methods. The proposed solution provides a low-cost, loom-integrated approach that enhances productivity while preserving fabric integrity and traditional weaving practices.
