植物性系统表现出对压力、光、化学品或温度等刺激的非定向结构反应;适湿性是指对水分有特异性反应的系统。许多种子传播机制，如小麦芒，豆荚，云杉和松果属于这一分类。从打开和关闭到自挖，各种行为变化很大，但其机制是基于两个相邻组织区域之间的不同吸湿膨胀。我们通过结构层次的透镜，描述了在纺织品框架内应用湿弹性原理。两个新的原型。一种是在潮湿条件下增加其对气流的渗透性，并在干燥条件下降低25- 30%的渗透性，这与传统的棉，羊毛和人造丝纺织品相比是一种违反直觉的特性，随着其水分含量的增加，它们对气流的渗透性会降低。第二个原型描述了一种吸湿变形纤维的设计和开发，这种纤维在潮湿条件下的长度与干燥条件下相比能够减少40%。
Botanical nastic systems demonstrate non-directional structural responses to stimuli such as pressure, light, chemicals or temperature; hygronasty refers to systems that respond specifically to moisture. Many seed dispersal mechanisms such as wheat awns, legume pods, spruce and pinecones fall within this classification. The variety of behaviours varies greatly from opening and closing to self-digging, but the mechanism is based on differential hygroscopic swelling between two adjacent areas of tissue. We describe the application of hygronastic principles specifically within the framework of textiles via the lens of structural hierarchy. Two novel prototypes are presented. One is designed to increase its permeability to airflow in damp conditions and reduce permeability in the dry by 25–30%, a counterintuitive property compared to conventional cotton, wool and rayon textiles that decrease their permeability to airflow as their moisture content increases. The second prototype describes the design and development of a hygroscopic shape changing fibre capable of reducing its length in damp conditions by 40% when compared with dry.
