[Script Info] Title: [Events] Format: Layer, Start, End, Style, Name, MarginL, MarginR, MarginV, Effect, Text Dialogue: 0,0:00:03.84,0:00:07.81,Default,,0000,0000,0000,,Yarn numbering is a term used to describe a yarn's physical size, Dialogue: 0,0:00:08.08,0:00:09.19,Default,,0000,0000,0000,,or more specifically, Dialogue: 0,0:00:09.32,0:00:10.56,Default,,0000,0000,0000,,its linear density. Dialogue: 0,0:00:11.37,0:00:14.88,Default,,0000,0000,0000,,Since short-stable spun yarns, like those containing cotton, Dialogue: 0,0:00:15.01,0:00:16.90,Default,,0000,0000,0000,,can vary greatly in their bulk, Dialogue: 0,0:00:17.21,0:00:20.00,Default,,0000,0000,0000,,measuring a yarn's diameter in a consistent way Dialogue: 0,0:00:20.17,0:00:21.60,Default,,0000,0000,0000,,can be almost impossible. Dialogue: 0,0:00:22.21,0:00:22.83,Default,,0000,0000,0000,,For this reason, Dialogue: 0,0:00:22.91,0:00:27.57,Default,,0000,0000,0000,,it is necessary to employ a more precise way of describing a yarn's physical size. Dialogue: 0,0:00:28.56,0:00:31.19,Default,,0000,0000,0000,,There are two main methods for assigning a yarn number. Dialogue: 0,0:00:31.76,0:00:34.60,Default,,0000,0000,0000,,One method is called the direct yarn numbering system. Dialogue: 0,0:00:35.36,0:00:36.10,Default,,0000,0000,0000,,In this method, Dialogue: 0,0:00:36.26,0:00:40.11,Default,,0000,0000,0000,,the yarn's linear density is denoted as a weight to length ratio. Dialogue: 0,0:00:40.94,0:00:44.57,Default,,0000,0000,0000,,This method is commonly used for synthetic or man-made, fiber. Dialogue: 0,0:00:45.06,0:00:45.73,Default,,0000,0000,0000,,For example, Dialogue: 0,0:00:45.90,0:00:50.98,Default,,0000,0000,0000,,a 70-denier yarn means that there are 70 grams per 9000 meters. Dialogue: 0,0:00:51.90,0:00:54.84,Default,,0000,0000,0000,,Denier is just one of the direct yarn numbering units, Dialogue: 0,0:00:55.02,0:00:58.38,Default,,0000,0000,0000,,but it is one of the more common direct units used for synthetics. Dialogue: 0,0:00:58.99,0:01:01.06,Default,,0000,0000,0000,,The other method for describing a yarn's Dialogue: 0,0:01:01.06,0:01:03.51,Default,,0000,0000,0000,,linear density is called the indirect method. Dialogue: 0,0:01:04.06,0:01:04.70,Default,,0000,0000,0000,,In this method, Dialogue: 0,0:01:04.78,0:01:08.19,Default,,0000,0000,0000,,the yarn size is described in length to weight units. Dialogue: 0,0:01:08.62,0:01:09.74,Default,,0000,0000,0000,,For cotton yarns, Dialogue: 0,0:01:09.78,0:01:14.97,Default,,0000,0000,0000,,it's typical to see the denotations NCC, or sometimes NE. Dialogue: 0,0:01:15.54,0:01:19.79,Default,,0000,0000,0000,,These denotations are otherwise known as cotton count or number English. Dialogue: 0,0:01:20.31,0:01:21.10,Default,,0000,0000,0000,,For example, Dialogue: 0,0:01:21.27,0:01:22.96,Default,,0000,0000,0000,,a number English 30 single, Dialogue: 0,0:01:23.35,0:01:25.74,Default,,0000,0000,0000,,100% cotton or blend yarn Dialogue: 0,0:01:26.03,0:01:29.14,Default,,0000,0000,0000,,means 30 times 840 yards per pound. Dialogue: 0,0:01:29.75,0:01:32.12,Default,,0000,0000,0000,,840 yards is known as a hank. Dialogue: 0,0:01:32.59,0:01:33.58,Default,,0000,0000,0000,,When all this is said, Dialogue: 0,0:01:33.71,0:01:35.70,Default,,0000,0000,0000,,it's important to realize that there are other Dialogue: 0,0:01:35.70,0:01:38.03,Default,,0000,0000,0000,,yarn numbering units that may be encountered. Dialogue: 0,0:01:38.27,0:01:40.27,Default,,0000,0000,0000,,It's impossible to cover all of them. Dialogue: 0,0:01:40.67,0:01:43.63,Default,,0000,0000,0000,,This is especially true in China and some other foreign Dialogue: 0,0:01:43.63,0:01:47.14,Default,,0000,0000,0000,,countries, where many variations of yarn numbering may have evolved. Dialogue: 0,0:01:47.76,0:01:50.00,Default,,0000,0000,0000,,Be aware that not everyone speaks or even Dialogue: 0,0:01:50.00,0:01:52.72,Default,,0000,0000,0000,,knows all of these terms and their relationships.
