Shirts are the clothing products that people need in all seasons. The folding effect of shirt sleeves directly affects the quality of the sleeves. In this paper by controlling the fabric of the shirt, the folding pressure and the additional pressure time, the fold recovery performance of the sleeves are studied from three aspects: bending stiffness, wrinkle recovery angle and bending recovery force. The experimental results show that the greater the areal density of the fabric is, the greater the restoring force is, the less likely the sleeves are folded. Under operation time of 5 minutes, the pressure of 30 N, 40 N, 50 N is applied to the wool fabric and the polyester fabric respectively, the restoring force was 1.0 cN, 0.75 cN, 0.5 cN and 1.2 cN, 0.8 cN, 0.6 cN respectively. At the same time the experimental results show that, the greater the additional pressure is, the smaller the resilience is, and the better the folding effect of the sleeves is. The research in this paper provides a theoretical basis for the actual production of the folding of the shirt sleeves and improves production efficiency by controlling the relationship between negative pressure and negative pressure time.
