织物的抗起毛起球性能是影响服装性能的一个重要因素，服装面料起毛起球后会严重影响织物的外观性能。

The mechanism of pilling</p
The fibers on the surface of the fabric will produce hairs due to friction. The hairs are entangled with each other and intensify the pulling of the fibers. The entanglement becomes tighter and tighter to form pellets. If the strength is not enough to resist the force, they will fall off, otherwise they will remain on the cloth surface. superior �</p

Pilling assessment method: </p
国内标准主要涉及4种方法。
1. Circular trajectory method (GB/T4802.1-2008)</p
方法概述：取直径为113mm的圆形试样，测试面朝外安装在夹头上，磨台有两种材质的磨料，其中织物与尼龙刷摩擦起毛，与标准织物磨料摩擦起球。
Select the corresponding test parameters according to the fabric type, the list is as follows: </p
</p
摩擦后，在规定光照条件下对照视觉描述对样品进行评级，可评半级。1级差，5级好。
</p
2. Modified Martindale method (GB/T4802.2-2008)</p
Mostly used for pilling test of bedding</p
方法概述：在规定的压力下，圆形试样以李莎茹图形的轨迹与织物本身或标准羊毛磨料进行摩擦，试样能够绕与试样平面垂直的中心轴自由转动。
Different fabrics use corresponding parameters: </p
</p
经规定的摩擦阶段后，采用视觉描述的方式评定等级。可评半级，1级差，5级好。
</p
3. Pilling box method (GB/T4802.3-2008)</p
多用于含毛织物或仿毛织物的起球试验。
方法概述：将试样安装在聚氨酯管上，在具有恒定转速、衬有软木的木箱内任意翻转。在没有协议或规定的情况下，建议粗纺织物翻转7200转（即2小时），精纺织物翻转14400转（即4小时）。
经过规定的翻转次数后，对起毛和（或）起球性能进行视觉描述评定。可评半级，1级差，5级好。
</p
4. Random tumbling method (GB/T4802.4-2009)</p
Method overview: Seal the edges of a square sample cut at 45° along the longitude and latitude direction with adhesive and place it into a random tumbling pilling box covered with cork liner, and fill a cylindrical test with a small amount of gray short cotton. In the warehouse, it rolls and rubs at will due to the action of the impeller and air pressure. The friction process involves the friction between the specimen and the friction between the specimen and the liner. �30分钟后，在规定光源条件下，对起毛起球性能进行视觉描述评定� �</p
以上，同一块面料的起毛起球性能测试选择不同的试验方法，其测试的结果差异很大，所以应特别注意所选择的实验方法。需要考核的面料需按照相应的产品标准所要求的方法测试。
