Location: IN - India
Inventory refers to 1 kg knitted textile
This dataset covers  all relevant input and output flows of the represented gate to gate unit process with a good overall data quality. The inventory is  based on industry data. The dataset represents the Indian average of the knitted fabric manufacturing with circular knitting machines.
Knitting is a method by which thread or yarn may be turned into cloth by making consecutive loops called stitches. A new loop is pulled through each loop and a new loop is created. Knitting creates a fabric which is more stretchable and comfortable.
Circular knitting is a form of knitting that creates a seamless tube. Knitting is worked in rounds in a spiral (the equivalent of rows in flat knitting). This form of knitting is used to create T- shirt Jersey fabric and socks

Undefined unit processes (UPRs) are the unlinked, multi-product activity datasets that form the basis for all of the system models available in the ecoinvent database. This is the way the datasets are obtained and entered into the database by the data providers. These activity datasets are useful for investigating the environmental impacts of a specific activity (gate-to-gate), without regard to its upstream or downstream impacts.

Technology

Indian average, based on primary data collected from knitting unit, using current manufacturing technology in India.
Once the yarn is received in packaged form, it is placed in creel to feed the knitting zone into the feeder. Upon setting the specific yarn as per the fabric requirement, machine is set as per specific design requirement and the machine processes yarn into loops culminating into production of fabric.
