Description of ASTM-D1577 2001

ASTM D1577-01

Historical Standard: ASTM D1577-01 Standard Test Methods for Linear Density of Textile Fibers

SUPERSEDED (see Active link, below)

ASTM D1577

1. Scope

1.1 These test methods cover the measurement of mass per unit length (linear density) of textile fibers and filaments. Direct weighing and vibroscope procedures with modifications for crimped and uncrimped fibers are included. The options and sections are listed below.

Option Sections
AFiber Bundle Weighing 7-15
BSingle-Fiber Weighing 16-23
CVibroscope, General 24-30
35 and 36
C1Uncrimped Fibers 31 and 32
C2Crimped Fibers 33 and 34
Precision and Bias 37 and 38

Note 1For linear density of short lengths of yarn, refer to Test Method D 1059. For cotton linear density, refer to Test Methods D 1769, and D 2480. For measurement of wool diameter, refer to Test Methods D 1282, D 2130 and D 3510.

1.2 The crimp, taper and cross-sectional shape of the fiber may influence the linear density measured by single-fiber weighing and vibroscope.

1.3 These test methods measure the linear density of fibers with moisture in equilibrium with the standard atmosphere for testing textiles. The fiber moisture under these conditions is not necessarily the same as the commercial moisture regain for the fibers.

1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
