LPG vs LNG: the debate of which is the better industrial fuel?
India’s Textile Industry is the second largest textile industry globally, and the scenario started changing immensely after the LPG usage began in textile processes. The textile industry of India also contributes nearly 14% of the country’s total industrial production, and it not only generates jobs in its own industry but also opens up scopes for the other ancillary sectors.
LPG is used in the textile & garments industry for numerous applications like Singeing (burning off projected yarn for better fabric-finish), Calendaring, Drying after printing on fabrics and for Steam generation.
Drying process:
The air required for drying can be heated directly (from fuels, electric resistances, and quenching processes) and indirectly via heat exchangers.
Direct air heating using contaminating fuels such as oil and diesel make the air susceptible to contamination. Using LPG meets cleanliness requirements for numerous processes.
Singeing process:
Also called gassing, this process delivers an even surface by burning off projecting fibres, yarn ends, and fuzz. The yarn or fibre is passed over a gas flame or heated copper plates at speed necessary to burn the protruding material without harming the fabric.
Let’s have a look at the features of LPG powered singeing machines:
1) LPG powered singeing machines eliminate the pilling of polyester blends and improve the fabric surface along with retaining softness as the fabric tension is controlled throughout based on the type of fabric being singed.
2) LPG powered singeing machines offer flexibility with individual spindle drive, helping increase efficiency.
3) LPG powered singeing machines carry and offer excellent safety measures. The burners, control systems and auxiliary equipment are constantly monitored, and the equipment automatically turns off in the event of any malfunction.
4) LPG provides flame with high mechanical and thermal energy, quickly burning the thermoplastic protruding fibres without the formation of molten beads.
Benefits of using LPG for the various processes in the textile industry:
- Maintenance-free operation
- The smooth surface of the fabric
- Flexibility with an individual spindle drive
- Best fabric quality
- Impeccable fabric structure
- Reduced soiling tendency
- Clear outlines of patterns on the prints
