ASTM D – 99 Standard Test Method for Bow and Skew in Woven and Knitted Fabrics

Other fabrics with established test values may be used for this purpose. Bow and skew are more visually displeasing in colored, patterned fabrics such as plaids and horizontal stripes rather than in solid colors because the contrast makes the distortion more prominent. If there are differences of practical significance between reported test results for two laboratories or morecomparative tests should be performed to determine if there is a statistical bias between them, using competent statistical assistance.

Combining values from the two systems may result in non-conformance with the standard. The average bow or skew in a roll or lot or the range of bow or skew in a roll may be determined but are sstm normally used in the trade for acceptance or rejection.

Wavy or sharp breaks in the bow line are more detrimental to the appearance of small parts of a garment such as collars, pockets, and so forth than a gradual slope from a straight asym.

In some cases, a specified amount of skew is needed, for example, to prevent twisting of pant legs made of twill fabric.

If a bias is found, either its cause must be found and corrected, or future test results must be adjusted in consideration of the known bias.

The test results from the two laboratories should be compared using a statistical test for unpaired data, at a probability level chosen prior to the testing series. Matching plaids from distorted patterns may create serious problems for the garment manufacturer or home sewer. Remember me for one month. Wavy 3d882 sharp breaks in the bow line are more detrimental to the appearance of small parts of a garment such as collars, pockets, and so forth than a gradual slope from a straight line.

As a minimum, the test samples to be used are as homogeneous as possible, are drawn from the material from which the disparate test results were obtained, and are randomly assigned in equal numbers to each laboratory for testing. If a bias is found, either 3d882 cause must be found and corrected, or future test results must be adjusted in consideration of the known bias.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. These defects may cause sewing problems in such fabrics and draping problems in finished products.
