Standard Performance Specification for Woven, Knitted, or Flocked Bedspread Fabrics 机织、针织或植绒床罩织物的标准性能规范
发布日期: 2008-08-01
1.1本性能规范涵盖了用于制造床罩的机织物、针织物或植绒织物的性能要求。 1.2这些要求适用于与织物方向相关的特性的长度和宽度方向。 1.3 本标准并非旨在解决与其使用相关的所有安全问题(如有)。本标准的用户有责任在使用前制定适当的安全和健康实践,并确定监管限制的适用性。 ====意义和用途====== 用于该最终用途的织物应满足表1中列出的所有要求。 应该认识到,织物可以用几乎无限多的结构变量(例如,纤维类型、纤维百分比、纱线捻度、纱线数量、经纱和纬纱数量、化学和机械整理)生产。 此外,时尚或美学要求最终消费者可能会发现由不符合表1中所有要求的织物制成的可接受物品。 因此,没有任何单一的性能规范可能适用于可用于此最终用途的所有各种织物。 特定性能和测试方法的用途和意义在指定测试方法的适当章节中进行了讨论。 表1规范要求 笔记 -色牢度和DP等级的数值等级为5,表示可忽略或无颜色变化、颜色转移或褶皱,为1,表示非常严重的颜色变化、颜色转移或褶皱。表1中的数值额定值或更高的数值额定值是可以接受的。 特征 要求 部分 编织 编织 断裂强力(负荷) 最小25 lbf(111 N) . 5.1 爆裂强度 . 最小35 psi(241 kPa) 5.2 撕裂强度 最小1.5 lbf(6.7 N) 5.3 尺寸变化: 清洗和干洗(每个方向): 5.4.1 – 5.4.2 5.4.2 定制型 ± 最大3.5% ± 最大5.0% 投掷类型 ± 最大5.0% ± 最大5.0% 5.5.2.1 织物外观(耐熨烫) SA3.5分钟 SA 3.5分钟 手、性格和外表的保留 无重大变化 无重大变化 5.6 背涂层的耐久性 无重大变化 无重大变化 5.7 色牢度: 洗钱: 5.8.1 阴影变化 最低4级 A. 最低4级 A. 染色 最低3级 B 最低3级 B 漂白 5.8.2 次氯酸钠 最低4级 A. 最低4级 A. 无氯 最低4级 A. 最低4级 A. 干洗: 5.8.3 阴影变化 最低4级 A. 最低4级 A. 燃烧废气(两个循环) 阴影变化 5.8.4 起初的 最低4级 A. 最低4级 A. 一次清洗或一次干洗后 最低4级 A. 最低4级 A. 摩擦: 5.8.5 干的 最低4级 C 最低4级 C 潮湿的 最低3级 C 最低3级 C 光(20 AATCC标准衰减单元) 步骤-4分钟 A. 步骤-4分钟 A. 5.8.6 易燃性 通过 通过 5.9 A.

1.1 This performance specification covers the performance requirements for woven, knitted, or flocked fabrics to be used in the manufacturing of bedspreads. 1.2 These requirements apply to the length and width directions for those properties where fabric direction is pertinent. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== Fabrics intended for this end-use should meet all of the requirements listed in Table 1. It should be recognized that fabrics can be produced with an almost infinite number of construction variables (for example, type of fibers, percentage of fibers, yarn twist, yarn number, warp and pick count, chemical and mechanical finishes). Additionally, fashion or aesthetics dictate that the ultimate consumer may find acceptable articles made from fabrics that do not conform to all of the requirements in Table 1. Hence, no single performance specification can possibly apply to all the various fabrics that could be utilized for this end-use. The uses and significance of particular properties and test emthods are discussed in the appropriate sections of the specified test methods. TABLE 1 Specification Requirements Note —Class for colorfastness and DP rating is based on a numerical scale of 5 for negligible or no color change, color transfer, or wrinkle to 1 for very severe color change, color transfer, or wrinkle. The numerical rating in Table 1 or a higher numerical rating is acceptable.
