GB/T 7568.8-2014Textiles -- Tests for colour fastness -- Standard adjacent fabric -- Part 8: Secondary acetate (English PDF)

Foreword

GB/T 7568 Textiles - Tests for Color Fastness - Standard Adjacent Fabric is divided

into eight parts:

---Part 1: Wool;

---Part 2: Cotton and Viscose;

---Part 3: Polyamide Fiber;

---Part 4: Polyester Fiber;

---Part 5: Polyacrylonitrile Fiber;

---Part 6: Silk Fiber;

---Part 7: Multifiber;

---Part 8: Secondary Acetate.

This is Part 8 of GB/T 7568.

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

The modification of this Part adopts ISO 105-F07: 2001 Textiles - Tests for Color

Fastness - Part F07: Specification for Secondary Acetate Adjacent Fabric (English

version). In comparison with ISO 105-F07: 2001, the main differences are as follows:

---The title of the standard is modified into "Textiles - Tests for Color Fastness -

Standard Adjacent Fabric - Part 8: Secondary Acetate";

---International standards in the normative references are replaced by

corresponding Chinese standards; GB/T 3921-2008 and FZ/T 01024 are added;

ISO 105-C02: 1989 is deleted;

---The stipulations of raw materials, yarns and fabric structures of secondary

acetate adjacent fabrics are added to Appendix A.

This Part was proposed by China National Textile and Apparel Council.

This Part shall be under the jurisdiction of National Technical Committee 209 on

Textiles of Standardization Administration of China, Basic Standard Subcommittee

(SAC/TC 209/SC 1).

Supervision; National Cotton Printing and Dyeing Product Quality Supervision and

Inspection Center.

Textiles - Tests for Color Fastness -

Standard Adjacent Fabric - Part 8: Secondary Acetate

1 Scope

This Part of GB/T 7568 stipulates the basic requirements and assessment

requirements of unstained secondary acetate standard adjacent fabrics, which are

used in the assessment of staining properties in the tests for color fastness of textiles.

This Part is applicable to unstained secondary acetate adjacent fabrics, which are used

in the assessment of staining properties in the tests for color fastness.

NOTE: the staining properties of secondary acetate adjacent fabrics to be tested may be

compared and determined together with secondary acetate reference adjacent

fabrics through secondary acetate stained reference adjacent fabrics.
