1.1 本试验方法包括使用随机滚转起球试验机测定织物在织物上形成丸子的倾向和其他相关表面变化。该程序通常适用于所有类型的机织和针织服装面料。 注1: 关于纺织品抗起球性的其他测试方法，请参考测试方法 D3511/D3511米 , D3514/D3514M 和 D4970/D4970米 . 1.2 一些用硅酮树脂处理过的织物可能无法通过该程序进行令人满意的测试，因为硅酮树脂可能会转移到测试室内的软木衬垫上，并导致错误的结果。 1.3 以国际单位制或英磅单位表示的数值应单独视为标准值。每个系统中规定的值可能不完全相等；因此，每个系统应独立使用。组合两个系统的值可能导致不符合标准。 1.4 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 5.1 验收测试- 验收测试不推荐使用这种测试织物抗起球性的方法。如果用于验收测试，则应谨慎使用，因为- 实验室精度差。在某些情况下，采购商和供应商可能必须采用可用的最佳测试方法对一种或多种特定材料的商业装运进行测试，即使不建议采用该测试方法进行验收测试。 5.1.1 如果两个实验室（或多个实验室）报告的测试结果之间存在差异或实际意义，则应进行比较测试，以确定它们之间是否存在统计偏差，并使用合格的统计协助。至少，应使用尽可能均匀的测试样品，从获得不同测试结果的材料中提取，并以相等数量随机分配给每个实验室进行测试。 可使用具有既定试验值的其他材料。两个实验室的测试结果应使用未配对数据的统计测试进行比较，在测试系列之前选择的概率水平。如果发现偏差，则必须找到并纠正其原因，或者必须根据已知偏差调整未来的测试结果。 5.2 织物起球是一个非常复杂的特性，因为它受到许多因素的影响，这些因素可能包括纤维或混纺物的类型、纤维尺寸、纱线和织物结构、织物整理处理和翻新方法。 建议在翻新前进行测试。在实际穿着中，特定织物的抗起球性随着一般使用条件和个人穿着者的不同而变化，而不是在经过受控实验室测试的复制织物样品中。在采用任何一系列标准的可接受程度时，应牢记这一经验。 5.3 药丸的大小和外观差别很大，取决于皮棉的存在和颜色对比度。当起球仅根据药丸数量进行评定时，不评估这些因素。 药丸的发展可能伴随着其他表面现象，如失去覆盖、颜色变化或绒毛的发展。由于特定织物的总体可接受性取决于药丸的特性和影响表面外观的其他因素，因此建议实验室测试的织物应根据其可接受性进行主观评估，而不是仅根据开发的药丸数量进行评级。基于被测织物类型表面变化的分级程度，可以建立一系列标准，为主观评级提供依据。 当实验室测试样品在外观上与磨损的织物密切相关，并且显示出类似的丸状物与绒毛的比例时，视觉标准是最有利的。不建议对药丸进行计数，并根据药丸的大小和对比度对药丸的数量进行称重，作为抗起球性的综合衡量标准，因为计数、大小和计算所需的时间过长。 5.4 通过将测试样品与视觉标准进行比较，评估织物起球的程度，视觉标准可能是实际织物或织物照片，显示出一定范围的抗起球性。 观察到的起球阻力以5（无起球）至1（非常严重的起球）的任意比例报告。 5.5 该测试方法适用于各种各样的机织物和针织物，这些织物由于纤维、纱线和织物结构以及整理的变化而具有不同的起球倾向。

1.1 This test method covers the determination of the propensity of a fabric to form pills and other related surface changes on textiles using the random tumble pilling tester. The procedure is generally applicable to all types of woven and knitted apparel fabrics. Note 1: For other test methods for the pilling resistance of textiles, refer to Test Methods D3511/D3511M , D3514/D3514M , and D4970/D4970M . 1.2 Some fabrics that have been treated with a silicone resin may not be satisfactorily tested by this procedure because the silicone resin may transfer onto the cork liners in the test chamber and cause erroneous results. 1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 Acceptance Testing— This method of testing fabrics for resistance to pilling is not recommended for acceptance testing. If it is used for acceptance testing, it should be used with caution because the between-laboratory precision is poor. In some cases the purchaser and the supplier may have to test a commercial shipment of one or more specific materials by the best available test method, even though the test method is not recommended for acceptance testing. 5.1.1 If there are differences or practical significance between reported test results for two laboratories (or more), comparative tests should be performed to determine if there is a statistical bias between them, using competent statistical assistance. As a minimum, the test samples should be used that are as homogeneous as possible, drawn from the material from which the disparate test results were obtained, and randomly assigned in equal numbers to each laboratory for testing. Other materials with established test values may be used for this purpose. The test results from the two laboratories should be compared using a statistical test for unpaired data, at a probability level chosen prior to the testing series. If a bias is found, either its cause must be found and corrected, or future test results must be adjusted in consideration of the known bias. 5.2 The pilling of textile fabrics is a very complex property because it is affected by many factors which may include type of fiber or blends, fiber dimensions, yarn and fabric construction, fabric finishing treatments and refurbishing method. Testing before refurbishing may be adviseable. The pilling resistance of a specific fabric in actual wear varies more with general conditions of use and individual wearers than in replicate fabric specimens subjected to controlled laboratory tests. This experience should be borne in mind when adopting levels of acceptability for any series of standards. 5.3 Pills vary appreciably in size and appearance and depend on the presence of lint and degree of color contrast. These factors are not evaluated when pilling is rated solely on the number of pills. The development of pills may be accompanied by other surface phenomena such as loss of cover, color change, or the development of fuzz. Since the overall acceptability of a specific fabric is dependent on both the characteristics of the pills and the other factors affecting surface appearance, it is suggested that fabrics tested in the laboratory be evaluated subjectively with regard to their acceptability and not rated solely on the number of pills developed. A series of standards, based on graduated degrees of surface change of the fabric type being tested, may be set up to provide a basis for subjective ratings. The visual standards are most advantageous when the laboratory test specimens correlate closely in appearance with worn fabrics and show a similar ratio of pills to fuzz. Counting the pills and weighing their number with respect to their size and contrast, as a combined measure of pilling resistance, is not recommended because of the excessive time required for counting, sizing, and calculating. 5.4 The degree of fabric pilling is evaluated by comparing the tested specimens with visual standards, which may be actual fabrics or photographs of fabrics, showing a range of pilling resistance. The observed resistance to pilling is reported on an arbitrary scale ranging from 5 (no pilling) to 1 (very severe pilling). 5.5 This test method is applicable to a wide variety of woven and knitted fabrics that vary in pilling propensity as a result of variations in fiber, yarn and fabric structure, and finish.
