Design And Research Of Wearable Anti-extrusion Airbag Functional Clothing

In recent years,with the frequent occurrence of earthquakes,debris flows,landslides,industrial explosions and other accidents,the environment faced by rescuers participating in rescue operations has become more and more complicated.In 2019,geological disasters such as floods,severe typhoons,geological droughts,and earthquakes occurred in many places in China.The number of people affected in the year was as high as 130 million,and about 1.4 million houses were damaged to varying degrees,such as collapse,severe damage,General damage;emergency transfer of more than 5 million people,nearly 1,000 deaths and disappearances;the area of affected crops for farmers is as high as 19256.9 thousand hectares,causing nearly 30 thousand hectares of crop failure,resulting in a total loss of about 330 billion yuan for farmers and related personnel.When these disasters occur,professional rescuers and rescuers of various civil organizations play an important role in rescue.At the same time,how to better protect the life safety of rescuers has attracted more and more attention from the general public and the media,as well as relevant professional organizations that study protective products.Therefore,the performance improvement of personal protective equipment worn by rescuers has become a subject that urgently needs research and breakthrough.At present,in the global market,the annual sales of functional textiles are as high as 50 billion US dollars,and the demand for functional textiles in China is about 50 billion.It can be seen that functional clothing based on textile and clothing at home and abroad has become a research hotspot for scientific researchers,but the research on functional clothing is still based on general functional clothing that highlights fabric characteristics and improves sports comfort,lacking Research on professional protictive clothing worn in specific hazardous environments.Earthquakes,debris flows,landslides,industrial explosions,and other situations may cause secondary collapses and cause rescue workers to experience crush injuries.The emergency management department newly promulgated the ten typical cases of emergency rescue in China in the event of adisaster in 2019.Among them,building collapse accounted for 3 cases,landslides accounted for 2 cases,and industrial explosions accounted for 1 case.Aiming at this situation,this subject takes the ergonomic principles of clothing as the theoretical basis,and the safety protection performance and wearing comfort performance of functional clothing as the starting point.According to the existing rescue protective equipment,the optimal research is carried out to design the wearable anti-extrusion airbag function.Clothing,with a view to reducing the crushing injuries encountered by rescuers during the second collapse during the rescue process.In this topic,the design and research of wearable anti-extrusion airbag functional clothing mainly starts from the following aspects: First,based on the data of 162 cases of crush injury in the hospital,the AIS-ISS score is given to the crush injury to obtain the crush injury area and The strength provides data support for the design of the antiextrusion airbag function.Then,analyze the wearing environment of construction and rescue,combined with the large-scale movement requirements of construction and rescue,and sort out several common human movement forms,which are used as the dynamic size and loose requirements of the clothing structure.Finally,the design factors affecting the wearable anti-squeeze airbag functional clothing are analyzed,the research ideas for the design are proposed,and the samples are made,and the rationality and feasibility of the scheme are verified through the evaluation of real person try-on and the dummy anti-squeeze test.Based on the existing literature theory at home and abroad and the practical experience of airbag clothing,this paper designs and studies the wearable anti-extrusion airbag functional clothing,and the results can reduce construction and rescue personnel from crushing damage caused by collapse during the operation.
