IDFL 20-1防绒如何缝制试样
求助：IDFL 20-1防绒测试，这里面要求怎么缝试样，能否告知？帮帮忙比较急。本标准中缝纫针及针距都是有要求的：
using a 90 (14 USA) needle to sew 6 stitches per cm (16 stitches per inch).
具体制备过程请看如下步骤：
a. Prepare two test pillows for each filling-type to be tested.
b. Cut fabric to straighten the edges. Measure and cut fabric to 33 cm (13 inches) by 42 cm (16.75
inches).
c. Fold cut fabric in half with the outer sides (side of fabric that will be facing out in the finished product)
facing together on the inside of the fold. Folded fabric should now measure 21 cm (8 3/8 inches) by
33 mm (13 inches).
d. Stitch bottom and side seams 7 mm (1/4 inch) from the edges. Leave an opening at the top to form
an unfilled pillow shell.
e. Turn sewn fabric inside out with the (inner) sides facing together. NOTE: In order to obtain a smooth
second seam, it may be necessary to insert a ruler into the corner of the test pillow after turning to
completely push out the first seam.
f. Re-stitch the bottom and side seams 3 mm (1/8 inch) from the edges, encasing the first seams.
g. The test pillow is now ready for filling.
