TECHNICAL REQUIREMENTS 3.1 Material 3.1.1 Cloth Shall be woven from high-purity (99.95% minimum) fused silica (nominal density 2.2
13、 grams per cubic centimeter), Quartz 2 or Quartz 3 continuous-filament yarns as shown in Table 1 (See 8.2). TABLE 1 - YARN CLASSES Yarn Class Description 1 Quartz 1: The original quartz yarn was composed of (9 m) filaments. The yarn binder was composed of A - 1100 aminosilane with film formers and l
14、ubricants. Cloth woven from Quartz 1 is generally not commercially available. Quartz 1 is included in this table and Table 4 for comparison only (See 8.2). 2 Quartz 2: Quartz 2 is yarn composed of the same 0.000375 inch (9 m) filaments as quartz 1, but is made with a high performance yarn binder, wh
15、ich provides superior protection to the yarn during textile processing. In some cloth styles this has resulted in increases of 100% or more in cloth strength over the same styles in quartz 1. Quality is also greatly improved. 3 Quartz 3: The lower cost quartz 3 yarns are composed of 0.00054 inch (14
16、 m) filaments with the same high performance yarn binder as quartz 2. Quartz 3 is generally supplied as singles yarns, with a low twist, rather than the higher twist plied yarns of quartz 2.

Three general classes of finishes are provided b
27、y manufacturers in accordance with Table 3. The choice of finish and its specification shall be acceptable to purchaser. TABLE 3 - FINISH CLASSES Finish Class Description 1 Resin Compatible Yarn Binders: In addition to organofunctional silane coupling agents, these yarn finishes contain film former
28、and lubricants necessary to provide a weavable yarn. 2 Scoured Fabric: Fabric is washed to remove the film former and lubricant components of the yarn binder. The silane coupling agent in the quartz 2 and quartz 3 binder is only partially removed, and the scoured fabric is the finish of choice for s
29、ome resin systems. 3 Post Finished Fabric: Scoured fabric is treated with additional silane coupling agent having alternative organofunctionality to meet the needs of the purchasers resin system. Note: Nonplied low twist yarns such as 300 1/0, 125 1/0, and 125 2/0 require additional sizing for effic
30、ient weaving. Fabrics woven from these yarns, such as Styles 525, 4503, and 4581, should always be specified scoured or scoured and post finished. 3.1.1.2.1 The finish concentration shall be determined by loss on ignition. 3.1.2 Yarns Quartz yarns shall be in accordance with Table 4.
