Purpose

The change rules of the shielding effectiveness (SE) of the sleeve has not been clarified, which leads to the lack of the basis for the design, manufacture and evaluation of the electromagnetic shielding (EMS) clothing.

Design/methodology/approach

According to a simplified analysis model, a series of sleeve samples with different fabrics and styles are designed and manufactured. The SE of the sleeve is tested with the proposed special test method in a semi-anechoic chamber to analyze the influence of different factors on the SE of the sleeve.

Findings

The SE is greatly reduced about 60–90% after the fabric is manufactured into the sleeve. The larger the sleeve length is, the higher the peak value of the SE is. When the sleeve length is low, the SE value is easy to appear negative. As the cuff circumference increases, the SE of the sleeve will change with the frequency band. The influence of the cuff style on the SE of the sleeve mainly depends on the cuff width and style. The larger the cuff width is, the lower the overall SE of the sleeve is. The more wrinkles there are at the cuff, the better the SE of the sleeve is.

Originality/value

Our results provide a reference for the design, production and evaluation of the sleeve and the whole EMS clothing.

电磁屏蔽衣套屏蔽效果的影响因素及规律

目的

袖子的屏蔽效能（SE）的变化规则尚未弄清，这导致缺乏电磁屏蔽（EMS）服装的设计，制造和评估的基础。

设计/方法/方法

根据简化的分析模型，设计和制造了一系列具有不同面料和款式的袖子样品。使用建议的特殊测试方法在半消声室中对套筒的SE进行测试，以分析不同因素对套筒SE的影响。

发现

将织物制成袖子后，SE大大降低了60-90％。套筒长度越大，SE的峰值越高。当套筒长度短时，SE值容易出现负值。随着袖带周长的增加，袖子的SE将随着频带变化。袖口样式对袖子SE的影响主要取决于袖口的宽度和样式。袖带宽度越大，袖子的整体SE越低。袖口的皱纹越多，袖子的SE越好。

创意/价值

我们的结果为袖子和整个EMS服装的设计，生产和评估提供了参考。
