Primary data collection was conducted globally, based on regions in China, India, Bangladesh, Turkey, and Latin America representative of specific growing and manufacturing conditions. Primary data collection was accomplished in the form of spreadsheets and questionnaires, and supplemented by conversations with cotton growers, textile mills, garment sewers, and consumers. In cases where primary data were not available or were inconsistent, secondary data that were readily available from literature, machinery manufacturers, previous Life Cycle Inventory (LCI) studies, and life cycle databases were used for the analysis. The sources for any secondary data used are documented throughout the agricultural, textile, and use phase sections of this study report. Data on fabric production for both knits and wovens were collected from representative mills in each of the four regions (Turkey, India, China, and Latin America) with geographic differences for background energy systems. Background data for transport and raw materials were modeled with GLO boundaries. China, India, Turkey and Latin America represent approximately 51% of knit and 66% of woven world fabric manufacturing in 2009 (ITMF 2009). The mill data for textile production were supplemented with process energy calculations from machinery manufacturers and data available from Cotton Incorporated experts. Background data on ancillary materials, energy and fuels, transportation, and end-of-life were taken from the thinkstep AGs GaBi databases. Background data on use phase energy and materials were taken from existing thinkstep AG GaBi data. Background data on landfilling were taken from thinkstep AG GaBi databases.124Global average for textile production processes are based on a production mix from China, India, Bangladesh, Latin America, and Turkey. Weighted averages for each sub process within the textile manufacturing chain were created by the horizontal averaging method, based on the mills which actually perform each step.
The geographical coverage is a global average for cotton production and fabric manufacturing since data
were collected from the most relevant regions (highest production volume of cotton grown and amount
of fabric produced).
Knit and Woven fabric manufacture
o China (2 production sites)
o India (1 production sites)
o Turkey (4 production sites)
o Latin America (5 production sites)
o Bangladesh (1 production sites)The following processes are used to prepare cotton fiber for knitting or weaving into fabric: Opening / Cleaning, Carding, Predrawing / Prepreparation, Combing, Drawing, Roving, Spinning. These processes take in bales of ginned cotton then separate, blend, and condition the fiber for use in the subsequent textile processes.
The following processes are used to create Knit fabric from cotton fiber and give it desired properties such as color, texture, and finishes: Yarn Dyeing*, Backwinding, Creeling, Knitting, Batch Dyeing*, Finishing, Compaction. The knit fabric can either be Yarn Dyed, Batch Dyed, or neither, but never both.
The following processes are used to create Woven fabric from fiber and give it desired properties such as color, texture, and finishes: Beam / Slash / Dry, Weaving, Continuous Dyeing, Finishing, Sanforizing.cotton woven flow diagramPartly terminated systemAttributionalnoneAllocation is primarily by mass with one exception. During the manufacture of fabric, short fibers and noils were produced as valuable co-products and sold offsite. An economic allocation of impact to these flows was deemed reasonable because the fibers are used in teh same production system of textile manufacturing and because the noils are too valuable to be considered waste.95.0Cotton growth and cultivation data collection was determined based on the top cotton producing and exporting countries. According to the USDA, the top three cotton-producing countries are China, India, and the United States (67% of world’s production in 2014) and the top three exporting countries were the US, India, and Australia (28% of global exports) for the time period that the data collection represents (USDA, 2015a).
The cotton fabric manufacturing data included yarn production, fabric production, and preparation, dyeing, and finishing operations. Due to the sensitive and detailed data required from mills, companies were chosen based on knowledge of manufacturing processes and relationships with account representatives from Cotton Incorporated. According to ITMF data, Asia is the leading producer of yarn, woven fabric, and knit fabric, based on spindles installed and machinery shipments. (ITMF, 2012) Countries in Latin America were included to provide a more global look at the environmental effects of textile manufacturing, which is prone to location shifts as changes in trade policy and labor costs occur.Representative mills in each of the four regions were chosen to provide data abased on their technical representation of the current state of business and their wilingness to participate.2010-2014None.The data set represents a gate to gate unit process.No statementCotton Inc.Cotton Incorporated Global Life Cycle InventoryThe data set represents a gate to gate inventory. It can be used to characterise the supply chain situation of the respective processes in a representative manner. Combination with individual unit processes using this porcess enables the generation of user-specific (product) LCAs. The data set does not necessarily fit for any possible specific supply situation - especially if significantly different technology routes exist - but is representative of a common supply chain situation.thinkstep2019-02-01T00:00:00.000ILCD format 1.12019-02-01T00:00:00.00000.00.001Data set finalised; entirely publishedtrueOtherGaBi (source code, database including extension modules and single data sets, documentation) remains property of thinkstep AG. thinkstep AG delivers GaBi licenses comprising data storage medium and manual as ordered by the customer.
