Air Jet Loom

A loom that uses a jet of air to propel the weft yarn throughthe shed.

Energy Saving Coefficient

The energy efficiency improvement achieved by the air jet(ESC)

looms introduced by the project. This parameter is
pre-determined based on the weaving speed and the power
consumption by the loom motor of the project air jet loom
and the reference rapier loom.

Shedding

The process forming "the shed" by dividing the warp ends
into two sheets, providing a path for the weft. The shed isformed raising and/or lowering frames. Among the threemain types of shedding mechanisms, Cam, Dobby, andJacquard, the methodology is applicable when Cam and/or
Dobby shedding is applied.

measures

Summaryreduction The methodology is applicable to the project which newly
installs energy efficient air jet loom(s) or replaces existingloom(s) by energy efficient air jet loom(s) at a textile factory.
GHG emission reductions will be achieved through electricity
savings per unit of final product.

Calculation
emissions

ofreference Reference emissions are calculated by multiplying the projectelectricity consumption by the loom motor(s) of the project airloom(s), the default energy saving coefficient (ESC) provided
by the methodology, and the CO2 emission factor for electricity2

Calculationofproject Project emissions are calculated by multiplying the sum of theemissions

electricity consumption by the loom motor(s) of the project air
jet loom(s) and air compressor(s), and CO2 emission factor forelectricity consumption.

Monitoring parametersTotal amount of electricity consumed by the loom motor(s)of the project air jet loom(s).

Total amount of electricity consumed by the aircompressor(s) of the project air jet loom(s).

D. Eligibility criteria

This methodology is applicable to projects that satisfy all of the following criteria.
Criterion 1

The air jet loom(s) are introduced at a textile factory. The air jet looms
introduced as part of the project are equipped with energy saving technologies
such as an optimized shape reed’s tunnel of nozzles and a pressure sensor tomeasure air pressure of nozzles for optimization of compressed air
consumption of weft insertion.

Criterion 2

Periodical checks of the project air jet loom(s) are conducted at least once
every calendar year.

Criterion 3

Shedding mechanism of the project air jet loom(s) is either Cam or Dobby
shedding.

Criterion 4

The effective reed width of the project air jet loom(s) is less than or equal to190 cm.

F.1. Establishment of reference emissions
Reference emissions are calculated with the following parameters:
Total amount of electricity consumed by the loom motor(s) of the project air jet loom(s)[MWh/p];Default energy saving coefficient (ESC) provided by the methodology, that is determinedbased on the energy savings of the project air jet loom(s) compared to the reference rapierloom(s) [fraction]; and

CO2 emission factor for electricity consumed [tCO2/kWh].

Net emission reductions are achieved by adopting a conservative energy saving coefficient(ESC) as the methodology default value. ESC is determined as function of the loom motor'spower consumption and the weaving speed. Among various combinations of the weaving
speed and the loom motor power available for the type of fabric woven in the country, a set of
the weaving speed and the loom motor power, which lead to the most conservative ESC, areselected and used to determine the default ESC in the methodology for the project inBangladesh.
