Since ISO has been published in three parts, this standard has also been published in three parts. Certain conventions are, however, not identical to those used in Indian Standards. In this adopted standard, reference appears to certain International Standards for which Indian Standards also exist.
The corresponding Indian Standards which are to be substituted in their respective places are listed below along with their degree of equivalence for the editions indicated: International Standard Corresponding Indian Standard Degree of Equivalence ISO Textiles — Standard IS : Method for Technically Equivalent atmospheres for conditioning and conditioning of textiles testing ISO : Textiles — IS : Textiles — Domestic Identical Domestic washing and drying washing and drying procedures for procedures for textile testing textile testing Technical corrigendum 1 published in to the above International Standard has been given at the end of this publication.
The results obtained from different procedures may not be comparable. This part of ISO is not intended to measure the spirality of fabrics as manufactured, but rather the spirality after laundering. NOTE Some fabric constructions, such as denim, can have spirality intentionally introduced during manufacturing.
Fabrics made on circular knitting machines can have inherent nonverticality of wale alignment. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document including any amendments applies.
ISO , Textiles — Standard atmospheres for conditioning and testing ISO , Textiles — Domestic washing and drying procedures for textile testing 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. Spirality is measured in millimetres, percentage of a marked distance, or angle of nonverticality.
Cut three mm x mm single-layer fabric specimens aligned with the selvedge or tubular fold line in selected locations with different length and width yarns. Draw a line through each of the four sets of adjacent benchmarks to denote the square formed. Label the corners A, B, C and D in a clockwise direction starting at the lower left corner see Figure 1.
Cut three mm x mm specimens with the long dimensions aligned with the selvedge, or folded edge if the samples are a tubular knit. Place benchmark A perpendicular to the YZ line midway along the horizontal line.
Using a T-square device, mark point B mm above point A on the vertical line see Figure 4. Piace a mm x mm template on the fabric with the long direction paraiiei to the seivedge.
Cut a double thickness. NOTE The underlayer may not be aligned with a warp or wale line nor will the mm dimension necessarily be aligned with weft or course lines. However, pattern pieces for apparel assembly are typically aligned with selvedges rather than with warp or wale yarn lines.
Sew a 12 mm over-edged seam along each long direction and one short direction. Turn seams to the inside, forming an open-ended bag or pillowcase-type specimen to simulate a garment panel. Stitch the unsewn edges of specimen to make a hemmed edge. Calculate and report the mean percentage splrality for the specimens tested. NOTE This formula assumes that the angle between the two diagonals remains a right angle after laundering. In reality, due to shrinkage during laundering, this angle does not remain a right angle.
Hence, the spirality results obtained by this equation are an approximation of the actual spirality. Place the horizontal leg of a right-angle device along line AD so that the second leg Is perpendicular downward from point B. If desired. ISO ; b details of sample tested; c mean percentage spirality, or spirality distance millimetres ; d marking procedure used; e laundering procedure and type washer used; f number of laundering cycles.
Spirality can be in either direction. Page 2, 5. Page 3, 7. At the end of the fourth paragraph, add "[see Figure 6 c ]" so that the sentence reads: Measure and record distances aiong the seam iines, AB and CD, of each specimen [see Figure 6 c ]. Page 4, 9. Replace the second and third paragraphs by the following: Place the horizontal leg of a right-angle device along line AD so that the second leg is perpendicular downward from point B.

Review of Indian Standards Amendments are issued to standards as the need arises on the basis of comments.
Standards are also reviewed periodically; a standard along with amendments is reaffirmed when such review indicates that no changes are needed; if the review indicates that changes are needed, it is taken up for revision. This Indian Standard has been developed from DocNo.
