This Standard is applicable to evaluation on water efficiency for dyeing machine.2 Normative referencesThe following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. GB/T 8170, Rules of rounding off for numerical values & expression and judgement of limiting values GB/T 9995-1997, Determination of moisture content and moisture regain of textile - Oven-drying method FZ/T 01024, Instrumental assessment of change in colour for determination of grey scale rating FZ/T 90112-2018, Testing method of dyeing ratio for dyeing machine3 Terms and definitions3.1 dyeing machine the equipment used for dyeing and producing small batches of textiles using the dip dyeing process according to the prescribed procedures 3.2 constant mass weigh the textile materials at specified time intervals during the drying process; when the difference between the mass of two consecutive weighings is less than 0.1% of the mass of the last weighing, the mass of the latter weighing is Q - Water efficiency for dyeing machine, in cubic meters per ton (m3/t); W - Total water consumption during dyeing, in cubic meters (m3); see 6.4.2 for measurement method; M - Total mass of fabric during dyeing, in kilograms (kg); see 6.4.1 for measurement method. 6.2 Test equipment and installation In accordance with clause 5 in FZ/T 90112-2018. 6.3 Test steps The test steps are as follows: a) Install and check related equipment; b) Select and weigh the fabric as the dyed product; c) Select and weigh dyes and related additives; d) Boil and bleach or pre-treat the fabric. Wash clean; e) Dye according to the prescribed process; f) Make records of water volume as required; g) Wash after dyeing (the amount of washing water does not need to be measured); h) Evaluate dyeing results after drying; i) Calculate total water inflow, total water consumption and water efficiency. 6.4 Measurement 6.4.1 Fabric mass measurement Fabric mass measurement is carried out according to 6.1 in FZ/T 90112-2018. 6.4.2 Water consumption measurement 6.4.2.1 When the fabric does not need to be bleached, degreased or pre-treated before dying, use water intake test method to measure. The steps are as follows: a) Record the reading of the water meter before water inflow (P1). After the fabric is dyed according to the process requirements (without washing), record the water meter reading (P2). Use formula (2) to calculate the total water inflow P during the dyeing process. When the dyed product is yarn, the quality of the yarn is evaluated as follows: Use about 6% cheese. Take the inner, middle and outer layers of yarn. Weave into a small sample. Use standard color card for visual comparison. Or perform instrument evaluation according to FZ/T 01024. Color difference is not less than grade 4-5. 6.5.3 Equipment operation During the dyeing process, the equipment runs smoothly, without clogging or leakage of dye liquor. The cloth runs evenly, without entanglement or knotting, or abnormal noise (obvious noise). 6.6 Data rounding-off The calculation result of the water consumption of dyeing machine is rounded- off to two decimal places in accordance with the provisions of GB/T 8170.7 Test reportThe test report of water efficiency for dyeing machine includes the following: a) Basic information of the equipment to be tested: name, model specification, exit-factory number and production date; b) Test fabric varieties, fiber composition, specifications, color requirements; c) Equipment name and model; d) Test methods and measurement parameters used (liquid injection or drainage measurement method, fabric mass, dye liquor mass); e) Basic condition of test process; f) Measurement calculation table of water efficiency for dyeing machine; g) Determination report table of water efficiency for dyeing machine; h) Evaluation conclusion of water consumption of dyeing machine; i) Testers, reviewers, approvers, test dates. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
