17、 shall be plain with 2 warp yarns weaving as 1, except that at the selvage there shall be 3 warp yarns weaving singly . 3.2.5 Type VI. The weave of Type VI shall be what is commercially known as “nonelastic“ and shall be in accordance with Figure 1. The ground and binder warp ends shall be 2 ply. Th

18、e stuffer warp ends shall be 5 ply. The filling yarn shall be evenly distributed between the face and back of the tape and webbing. The 1 inch shall contain 24 ends in each selvage or 12 ends in each selvage. 3.2.6 Filling yarn. The weave for all types shall be with one filling yarn per shed when a

19、shuttle loom is used. The weave for all types shall be with two filling yarns per shed when a shuttleless loom is used (see 6.2). 3.3 Construction and physical properties. The construction and physical properties of the tape and webbing shall be as specified in Table I. When latch type shuttleless l

20、ooms are utilized, the filling yarn shall traverse the full width of the tape and shall be held at the edge by an extra catch-cord end interlacing with the filling yarn, in a method depicted in Figure 2 or 3. When bobbin type shuttleless looms are utilized, interlacing of the catch-cord and filling

21、shall occur within the selvage area before the first binder end (Figure 4). 3.4 Extractable matter. The natural color tape and webbing shall con- tain no more than 5.0 percent methyl-ethyl ketone extractable matter, and the dyed tape and webbing shall contain no more than 4.0 percent methyl-ethyl ke

22、tone extractable matter, when tested as specified in 4.3. 3.5 Acidity (pH). The water extract of the tape and webbing shall have a pH of 6.0 to 8.0, when tested as specified in Table IV. 3.6 Compatibility with dope. The Type I tape and webbing shall. be compatible with aircraft dope. The dope shall

23、dry within 45 minutes and show no signs of cracking and peeling when applied to the finished tape and webbing as specified in 4.4.2. 3 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-A 6 C ,D E F MIL-T-5hbLE 83 W I- Oh 0375245 2 - MIL-T-5661 E A.
