FZ/T 60031-2020Testing method for surface appearance and dimensional change after steam-press for garment interlinings (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces FZ/T 60031-2011 "Test Method for Dimensional Change of Clothing Linings After Steam Ironing". With FZ/T 60031-the main technical changes compared to 2011 are as follows.

---The standard name is adjusted to "Test Method for Appearance and Dimensional Change of Clothing Interlining after Steam Ironing";

---Adjusted the standard range;

---Adjusted the principle (see Chapter 3);

---In equipment and utensils, the standard fabrics (see 4.4, 2011 edition of 4.4) and the requirements of measuring tools (see 4.6, 2011 edition of 4.6), the evaluation sample photos are added (see 4.8);

---The operating procedure supplemented the sample size and quantity requirements (see 5.1), deleted the pre-conditioning time (5.3 in the 2011 edition), adjusted Humidity conditioning balance time (see 6.1.3, 6.2.5, 6.1.4, 6.2.6 of the 2011 edition);

--- The result evaluation adds the requirements for the evaluation of appearance changes (see 7.1), and the evaluation of appearance changes is based on the grade of the sample with the lower grade.

Accurate, the dimensional change rate is the average of two samples.

This standard was proposed by the China National Textile and Apparel Council.

This standard is under the jurisdiction of the Cotton Textile Subcommittee of the National Textile Standardization Technical Committee (SAC/TC209/SC10).

4.3 Appropriate marking printing device.

4.4 Standard fabrics. comply with FZ/T 01076 regulations.

4.5 Cutting knife.

4.6 Steel ruler. comply with GB/T 19022, its length is greater than 300mm, and the graduation value is 0.5mm.

4.7 Stopwatch.

4.8 Evaluation sample photos.

5 Sample preparation

5.1 Preparation of non-adhesive lining samples. cut out two samples at a distance of 10cm from the edge of the cloth and 1m from the end of the cloth, with a size of 300mm×300mm. test
