FZ/T7m1—1991 wool yarn, wool yarn 3. This standard is the matching standard of wool knitting and knitting yarn, and the standard number of the car is I2/T700:111. The standard is difficult to change to, and the test method for knitting and knotting yarn is applicable to: the scope of application is: applicable to about flying, the new wool knitting yarn is my neck braided wool war, and the product standard rate is limited to the two-way test method, and the part of the negative Japanese test method is added; when the product is used in the form of the standard test method, the product standard special items are listed in the form of the screen public: - Appendix A is currently serving the medical insurance single heart and the Meigeya consumption written in the form of the old original standard A. The attachment of this standard is the attachment of the qualification.
This standard is from China! This standard was proposed by the Textile Industry Association. This standard was drafted by the Beijing Institute of Technology. The main chapters of this standard are as follows: -FJ 383.--381, F2/[1-199: .
1 Scope
