The thread must process under p
9、roduction conditions without any reservations. Suppliers deliveries can be rejected because of excessive rates of breakage and/or other manufacturing difficulties (knots, foreign matter, stretch etc.). In addition, after sewing, the thread shall not exhibit objectionable streaks or any color change
10、in hue or purity of color. 3.6 NUMBER OF KNOTS The thread spool shall be free of all imperfections of such character which would cause the thread to break during sewing. 3.7 IDENTIFICATION Each spool of thread must bear the name of the manufacturer, color suffix, and yarn size. 3.8 PACKING The mater
11、ial must be packed in such a way that in transit no slippage of the layers or any other damage occurs. 4.
