Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces FZ/T 52019-2011 "Lysel Short Fiber", compared with FZ/T 52019-2011, except editorial modification
The technical changes are as follows.
--- Expanded the scope of application of the standard (see Chapter 1, Chapter 1 of the.2011 edition);
--- Revised the normative reference documents according to the latest release of the standard (see Chapter 2, Chapter 2 of the.2011 edition);
--- "Terminology and definitions" section added "fibrillation of lyocell staple fiber", "crosslinked lyocell staple fiber", "wet wear frequency definition
(See Chapter 3, Chapter 3 of the.2011 edition);
---In the "Classification and Labeling" of the product, "the product is classified into ordinary type and cross-linked short fiber according to the degree of fibrillation.
GL means; cross-linking type means "content" (see Chapter 4, Chapter 4,.2011);
---Modified "Technical Requirements" (see Chapter 5, Chapter 5 of the.2011 edition);
--- Increased the number of "wet wear times" assessment items and cross-linking indicator values (see Chapter 5, Chapter 5 of the.2011 edition);
--- Increased the "wet wear times" test method (see Appendix A).
This standard was proposed by the China National Textile and Apparel Council.
This standard is under the jurisdiction of Shanghai Textile Industry Technical Supervision.

Lysell staple fiber
1 Scope
This standard specifies the classification and marking, technical requirements, test methods, inspection rules and signs, packaging, transportation and storage of lyocell staple fibers.
Requirements.
This standard is applicable to lyocell staple fibers with a fiber density of 0.90 dtex to 6.70 dtex, which are produced from fiber-grade wood pulp.
His type of lyocell fiber can be used as reference.

3 Terms and definitions
The following terms and definitions, as defined in GB/T 3291.1, GB/T 3291.3 and GB/T 4146 (all parts), apply to this document.
3.1
Fibrillated lyocelstaplefiberfibrilation of lyocell staple fiber
Under the action of wet mechanical action, the lyocell staple fiber cortex appears to be cleft.
3.2
Cross-linked lyocell staple cross-linkedlyocelstaplefiber
Modified by a crosslinking agent and an additive to crosslink the fiber molecule and the crosslinking agent molecule to reduce the fibrillation tendency of the lyocell
fiber.
3.3
Wet wear number wetabrasionnumber
Under certain conditions, the fiber rubs on the friction shaft to the number of rotations of the friction shaft at the time of fracture.
