Translated from Khimicheskie Volokna, No.2, pp. 48–50, March–April, Author: I. V. Lokshina, O. G. Pikovskaya, Z. G. Serebryakova, L. G. Tokareva, G. S. Khorovodnov, N. N. Syach. c) 50m for spun yarn having a linear density of more than tex; d) 10m for multifilament yarns having a linear density of more than tex. In case of folded and cabled yarns, the limiting linear density stated applies to the resultant yarn linear density. If it is desired to combine the determination of linear density as.

Package weight and density: The package weight and density are two important parameters which are to be standardized for uniform and trouble free packages may be soft or hard these should conform to the standards, when too soft liquor flowing through it will find the course of least resistance and cause channeling, which leaves some parts of the package relatively undyed or lighter. * GB/T Textiles—Determination of the abrasion resistance of fabrics by the Martindale method—Part 1:Martindale abrasion testing apparatus * GB/T Textiles—Yarns from packages—Determination of single-end breaking force and elongation at break using constant rate of extension(CRE) tester.

Designation D − 07 Reapproved Standard Test Method forLinear Density of Elastomeric Yarns Skein Specimens1This standard is issued under the fixed designation D; the number immediately foll, The packing density of membrane is an important parameter in the design of MBR systems. Configurations of membrane module are limited to FS and HF for submerged MBR processes. HF membrane modules have been widely used due to high packing density and cost-effectiveness (Cui et al., ; Le-Clech et al., ).

Cancels and replaces the first edition (). Specifies a method for the determination of the linear density of all types of yarn in package form. Includes seven optional procedures based on different methods of conditioning and preparation.

This method is applicable to Price: $ This quantity is known as the linear density and it can be measured with a high degree of accuracy if a sufficient length of yarn is used.

There are two systems of linear density designation in use: the direct and the indirect. Direct System The direct system of denoting linear density is based on measuring the weight per unit length of a yarn. Cancels and replaces the first edition ().

Specifies a method for the determination of the linear density of all types of yarn in package form. Includes seven optional procedures based on different methods of conditioning and preparation. This method is applicable to Category: p.

Specifies a method for determination of the linear density of all types of yarn in package form. Applies to: cabled yarns, single yarns (spun, monofilament or multifilament and folded (plied) yarns. Does not apply to yarns having a linear density greater than 2, tex.

ISO specifies a method for the determination of the linear density of glass-fibre, carbon-fibre, aramid-fibre and any other reinforcement-fibre yarns. It is applicable to all types of yarn, including single yarns, double and cabled yarns, textured yarns, rovings and staple-fibre ry: p.

Method for determination of the linear density of yarns from packages Status: Superseded, Withdrawn Published: December Replaced By: BS EN ISO This test method is intended primarily for the determination of the average linear density of yarns. However, the variations identified by the results may also provide useful information.

If the coefficient of variation is to be calculated, each skein must be weighed separately, and a larger number of skeins will need to be tested (as compared to the number of skeins to be tested for the.

This test method covers the determination of the linear density of all types of yarn in package form, subject to the limitations of size and stretch given in and Provision is made for expressing yarn linear density in all the traditional yarn numbering systems.

This method is. Cancels and replaces the first edition (). Specifies a method for the determination of the linear density of all types of yarn in package form.

Includes seven optional procedures based on different methods of conditioning and preparation. This method is applicable to. Note 1The linear density of yarns produced with jute, or glass, may also be determined by the following approved methods: Specifications DDand D The linear density of short yarn segments, raveled from fabrics, may be determined by Test Method D Measurement of Linear Density: Yarn linear density is often measured using standard test method ASTM D Specified lengths of yarn are wound on reels as skein, and then weighed.

From this the linear density is calculated from the weight and length of the skein. NOTE 1—For a method designed specifically for testing rubber threads, refer to Test Method D This test method is not applicable to covered, wrapped, or core-spun yarns or yarns spun from elastomeric staple.

This test method is applicable to elastomeric yarns having a range of 40 to dtex (36 to denier).File Size: 34KB. Textiles - Yarn from packages - Determination of linear density (mass per unit length) by the skeinmethod (ISO ) Subscribe on standards with our subscription service.

Heavier yarns may be also tested providing the test conditions are acceptable to all interested method is not applicable to glass yarns which, in equilibrium with the Author: ISO TC 61/SC 13/WG the fibre distributions for each system.

For this purpose, % Tencel LF yarns with tex linear densities are produced on ring, compact and vortex spinning systems. Cross-sections have been made by hard sectioning method using a rotary microtome. Packing densities of yarns are calculated by image analysis method. BS EN ISO Textiles. Yarn from packages.

Determination of linear density (mass per unit length) by the skein method Status: Current, Under review Published: August For the determination of linear density of elastomeric yarns using short length specimens, refer to Test Method D The method is not applicable to covered, wrapped, or core-spun yarns, or yarns spun from elastomeric staple, or elastomeric yarns removed from fabrics.

This test method covers the determination of the yarn number of all types of cotton, woolen, worsted, and man-made fiber yarns taken from packages; or from any textile fabrics in which the yarns are intact and can be removed in measurable lengths.

DETERMINATION OF LINEAR DENSITY (MASS PER UNIT LENGHT) BY THE SKEIN METHOD. (ISO ). is classified in these ICS categories: Price Range: $ - $In the direct system, the linear density of plied yarn is the simple summation of linear densities of the individual components, i.e.

linear density (R) = T 1 + T 2 + T 3 + + T N, where T 1, T 2 T N are the linear densities of n individual components expressed in tex. The tex system has units measured in grams (g) per 1, metres (m).This test method covers the determination of the linear density of all types of yarn in package form, subject to the limitations of size and stretch given in and Provision is made for expressing yarn linear density in all the traditional yarn numbering systems.
