Abstract:

Objective The research and development of special protective clothing is of vital importance for ensuring the safety of personnel in high-risk industries. Currently, most of the saw-resistant clothing in China are developed by imitation, which have problems such as poor wearing comfort. To effectively protect the occupational health of practitioners of hand-held electric chain saws, a series of saw-resistant clothing that meet the requirements of both protection and comfort and conform to ergonomics have been developed.

Method The characteristics of saw-resistant clothing were analyzed and summarized by 86 types of saw-resistant clothing collecting from both domestic and foreign. 6 types of clothing fabric and 6 types of saw-resistant interlayer fabric were selected to compare and analyze their air permeability, moisture permeability, insulation, abrasion resistance, tear strength and saw-resistant performance respectively. The comprehensive performances evaluation of the saw-resistant materials were conducted by the gray near-optimal method in order to select the best garment fabric. 10 male volunteers with body type close to 175/92A were invited to complete the ergonomic evaluation for four types of self-design saw-resistant suit.

Results It was found that the style variations of the saw-resistant jackets mainly focus on the aspects such as silhouette, collar type, sleeve type, cuffs, pockets and opening design, while the style variations of the saw-resistant pants are mainly reflected in the functional designs such as waist, pockets and knees. To ensure the protective performance of saw-resistant clothing, the outer fabric of saw-resistant clothing usually adopts woven fabric with good wear resistance, and the protective interlayer between the fabric and the lining is made of multi-layer cut-resistant fiber fabric or blocking materials. The research conducts style and structure design based on the design principles of sportswear, and fully considers factors such as wearing occasions and working methods, improving the comfort, functionality and safety of saw-resistant clothing. The comfort and mechanical performance indicators of six kinds of outdoor sportswear fabric were compared in the experiments. It was found that the Cordura fabric had outstanding breathability, moisture permeability, wear resistance and tear resistance, the lowest heat preservation rate, and good heat dissipation effect. The performance of the six kinds of saw-resistant fabric were comprehensively evaluated. It was found that the UHMWPE fabric had the best comprehensive performance. The number of cutting layers of saw-resistant fabric is inversely proportional to its tightness. The greater the tightness of the fabric is, the fewer the number of cutting layers is, and the better the saw-resistant performance will be. The higher the breaking strength and elongation at break of the fibers are, the better the saw-resistant performance of the fabric will be. By comparing the ergonomic test results of four kinds of saw-resistant jacket and four kinds of saw-resistant pants, the movement freedom of saw-resistant jacket is higher than that of saw-resistant pants. Elastic fabric can provide sufficient movement freedom for clothing. The structural design method of continuous cutting of the shoulder and sleeve can reduce the restrictions on arm movement. The comprehensive score of the third type of saw-resistant suit is the lowest which indicates that this type of suit can better meet the ergonomic requirements, and has good sport comfort and activity freedom. This type of saw-resistant suit is almost unrestricted during movement and has a relatively reasonable structural and style design.

Conclusion This paper focuses on product design from aspects such as functionality, practicality and comfort, and develops saw-resistant clothing that meets the needs of electric chainsaw operators, minimizes potential occupational hazards for practitioners. It provides a theoretical basis for improving the safety protection effect and wearing comfort of anti-cutting clothing, which is conducive to promote the healthy development of the domestic saw-resistant clothing market and provide theoretical support and technical references for saw-resistant clothing manufacturers.
