Though no data are available for the specific waste flows for this process their contribution to the environmental impact of this process can be assumed as low. Water losses due to evaporation are not recorded.0The data set represents the country / region specific situation, focusing on the main technologies, the region specific characteristics and / or import statistics.In a printing process the colour is applied to the fabric to defined areas to obtain the desired pattern. The physical and chemical processes between dye and fibre are analogous to dyeing processes, but different techniques are involved. Typically the following steps are carried out: Colour paste preparation: the dye or pigment is finely dispersed in a printing paste in high concentration Printing: printing paste is applied to the substrate Fixation: immediately after printing the fabric is dried and the prints are fixed with steam or hot air (pigment printing) After treatment: washing and drying the fabric (not necessary for pigment or transfer printing) The composition of the paste is determined by the printing technique, the substrate, and the fixation method. The printing paste contains many different chemicals, such as thickening agents, oxidizing and reducing agents, hydrotropic substances like carbamide (urea), and solubilizing agents such as glycerine or glycols. These ingredients are metered and alloyed in a mixing station. In the analyzed process eight colours are printed to viscose fabric. For the printing paste cationic dyes are used. They are nowadays used only for acrylic fibres, polyamide fibres and blends. Cationic dye molecules contain a quaternary amino group. They are fixed to the fibre by ionic bonds between the cation in the dye and an anionic site in the fibre. Estimated runtime for mixing process 10 min.Provision of a standard technical product according to the applied technology.f316afd5-9008-11db-b606-0800200c9a66_textile_cationic dye preparation for printing.jpgUnit process, single operationAttributionalNoneNot applicableFor details please see the document "GaBi Databases Modelling Principles"All data used in the calculation of the LCI results refer to net calorific value.NoneCut-off rules for each unit process: Coverage of at least 95 % of mass and energy of the input and output flows, and 98 % of their environmental relevance (according to expert judgement).

The documentation includes all relevant information in view of the data quality and scope of the application of the respective LCI result / data set. The dataset represents the state-of-the-art in view of the referenced functional unit.thinkstepIABP-GaBiIBP-GaBiThe dataset and systems, which are provided with our software and databases for public use into a broad user community, are constantly used, compared, benchmarked, screened, reviewed and results published in various external, professional and third party LCA applications in industry, academia and politics. So user feedback via the online GaBi forum or direct via user information is a standard routine in the maintenance and update process and leads to stable quality and constant control and improvement of data, if knowledge or technology improves or industrial process chains develop or change.GaBi user forumGaBi bug forumGaBi user communityGaBi conformity systemFully compliantFully compliantFully compliantFully compliantFully compliantNot definedUNEP SETAC Life Cycle InitiativeNot definedNot definedNot definedNot definedNot definedNot definedILCD Data Network - Entry-levelNot definedNot definedFully compliantNot definedNot definedNot definedthinkstepThe data set represents a cradle to gate inventory. It can be used to characterise the supply chain situation of the respective commodity in a representative manner. Combination with individual unit processes using this commodity 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 for a common supply chain situation.thinkstep2020-01-01T00:00:00.000ILCD format 1.1thinkstepNo official approval by producer or operator2020-01-01T00:00:00.00000.00.001Data set finalised; entirely publishedGaBi databasesthinkstep / ENEAtrueOtherGaBi (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.
