The Yarn Heat Setting process is the process in textile industry that takes place between yarn twisting & cloth weaving. The polyester yarn (POY) needs to be twisted before the cloth is weaved, depending on the quality of the cloth required, POY is given twists (2000 to 3000) on twisting machines in order to give sufficient strength. After twisting POY gets curls if loosely held & will create problems while weaving. To avoid curling effect yarn is heated at specified temperatures, either by direct steam (temperature requirement – 105 to 120 deg celsius) / hot air (temperature requirement – 120 to 140 deg celsius) / steam in vacuum chamber (temperature requirement – 85 to 105 deg celsius). This process is known as HEAT SETTING OF YARN. Conventionally heat setting of yarn was done with the help of small non-IBR boilers Most of the boilers operate on LPG & few of larger capacity (300kg/hr & bigger) operate on diesel.

 

To support textile industry in wip-off a major part of their expenditure towards fuel costs while heat setting the yarn and as part of the developmental activity, few year back Gujarat Gas launched a specific application for small textile units, looms which uses/processes various quality of Yarn for processing. The different qualities of Yarn requires heating by which it gets Oriented (Straightened).

 

PNG is mainly adopted as an alternate of commercial LPG.

Majority of the installation and operational processes are similar to the commercial segment.

 

The Yarn Heat Setting (YHS) customers can be broadly categorized as under;

GGCL has a well identified and defined process for reaching out to its new customers in addition to the customer enquiries for new connection; company also carries out surveys from time to time in the potential areas. Under the above category, customers shall be required to pay;

1. Security deposit against gas sales equivalent to the actual monthly consumption bill amount termed as (“SD-G”) 
2. Installation charges at actual.  
3. Gas would be sold in mmbtu and all the relevant information would be provided in the gas bill.

 

The customers applying for new connection are categorized into two types;

On-Line Customers:
The customers whose units/entity are where PNG underground PE line network is available; may be referred to as “On-line” customers.

 

The customers whose units/entity are where PNG underground PE line network is not-available and required to be extended/laid, may be referred to as “Off-line” customers.
In order to book customers belonging to these two categories, separate procedure and time lines are followed. Generally it is easier and fast to connect online customers as the main network is already laid. In case of offline customers at times waiting period is higher as company has to first create a network in that area. The following steps have to be followed to avail a new PNG connection;
1. Submission of duly filled Customer Profile form
2. Signing of GSA (Gas Sales agreement)
3. Submission of relevant documents like address proof, customer identity proof
4. Payment of money

 

The documents required to avail the connections include;

Potential customer (all segments) information is captured in the system so that they can be contacted for PNG connection. Details of the same can be obtained from Customer Care Centre available on ph. No.:992400 5000 or in person at Gujarat Gas location offices.
