ISO12947 Martindale Abrasion And Pilling Tester—Determination of the abrasion resistance of fabrics

1 ขอบเขต

This document specifies the procedure for the determination of specimen breakdown (end-point of test) by inspection at fixed intervals and is applicable to all textile fabrics including nonwovens apartfrom fabrics where the specifier indicates the end performance as having a low abrasion wear life.

This document is not applicable to coated fabrics (including laminated fabrics). If the abrasion behaviour of the coated surface of a coated fabric is to be determined, use the methods described in the various parts of ISO 5470.

2. หลักการ

A circular specimen, mounted in a specimen holder and subjected to a defined load, is rubbed against an abrasive medium (standard fabric) in a translational movement tracing a Lissajous figure, the specimen holder being additionally freely rotatable around its own axis perpendicular to the plane of the specimen. The evaluation of the abrasion resistance of the textile fabric is determined from the inspection interval to breakdown of the specimens.

The specimens are mounted in specimen holders with foam backing. Specimens with a mass per unit area ≥500 g/m2 are mounted in specimen holders without foam. Pile fabrics which are tested without foam backing are subjected to a specified preparatory treatment

Two abrasion load parameters are specified. The total effective mass of the abrasion load (เช่น. the mass

of the specimen holder assembly and the appropriate loading piece) are as follows:

ก) (795 ± 7) g for fabrics intended for workwear, upholstery, bed linen and fabrics for technical use

(เช่น. a nominal pressure of 12 KPA);

ข) (595 ± 7) g for fabrics intended for apparel and household textiles, excluding upholstery and bed

linen (เช่น. a nominal pressure of 9 KPA).

Abrasion testing is continued up to breakdown of the test specimen.

The inspection interval is determined by the specimen breakdown. The number of rubs is recorded

at which specimen breakdown is not yet observed (this number of rubs is the upper limit of the time

elapsed before specimen breakdown and, ในเวลาเดียวกัน, the lower limit of the abrasion interval at

which specimen breakdown occurs)

Our machine Martindale Abrasion And Pilling Tester YG401E-4 is designed according to this standard and is currently widely used internationally.
