Preparation

The Preparation production stage covers the fabric processing that occurs after Textile Formation to clean the fabric, usually in preparation for dyeing. However, even fabrics that will not be additionally dyed use these processes to clean the fabric after Textile Formation. The Preparation production stage is a multi-select stage, which means that more than one process option can be chosen to apply at the same time within one fabric. Preparation process options generally apply to a range of fabrics:

(Acetate Triacetate fabric, Alpaca fabric, Cotton fabric, Flax fiber fabric, Hemp fiber fabric, Jute fiber fabric, Lyocell fabric, Modal fabric, Viscose/Rayon fabric, Wool fabric)

  • Preparation for dye (scouring, etc), knit textile, natural fibers should be selected when the fabric uses a Knitting process for Textile Formationand is being cleaned and/or prepared for dyeing. Since all Higg MSI Example Materials are knits, this is the default process selection.
  • Preparation for dye (scouring, etc), woven textile, natural fibers should be selected when the fabric uses a Weaving process for Textile Formationand is being cleaned and/or prepared for dyeing.

(Cotton fabric, Flax fiber fabric, Hemp fiber fabric, Jute fiber fabric,  Lyocell fabric, Modal fabric, Viscose/Rayon fabric)

  • Cellulase enzyme treatment, for appearance should be additionally selected when the fabric preparation additionally includes an enzyme treatment to improve the appearance and/or hand feel of a cellulosic fabric. This process should generally be selected in addition to, not instead of, a “Preparation for dye […]” process.

(Acrylic fabric, Nylon fabric, Polyester fabric, Polylactic Acid (PLA) fabric, Polypropylene (PP) fabric, Polytrimethylene terephthalate (PTT) fabric, Polyurethane (PU) fabric)

  • Scouring, synthetic fibers is the default selection for synthetic fabrics and is applicable when the fabric is being cleaned and/or prepared for dyeing.
  • Heat setting, textiles, preparation should be additionally selected if the synthetic fabric is being heat set after scouring before any further processing. This process should generally be selected in addition to, not instead of, the “Scouring […]” process.
  • Preparation for dye {Toray}, polyester filament woven fabric (includes data for dyeing and finishing) should be selected when using “Polyethylene terephthalate (PET) {Toray}, partially bio-based” raw material and when the fabric manufacturer is known to be Toray. When selecting this process, users should also select “Dyeing {Toray}, polyester woven fabric (empty process-impacts found in preparation process)” under the Coloration production stage and “Finishing {Toray}, polyester woven fabric (empty process-impacts found in preparation process)”under the Additional Coloration and Finishing production stage.
