The work aims to research and design a kind of planting yarn processing equipment that uses non-woven to cover grass seeds based on the concept of the tubular planting yarn, and apply the packaging machinery to the textile and garden fields combining textile materials with structural design. On the basis of the existing simple prototype machine, the grass seed conveyor, the forming device, the cloth heat sealing device and the winding device were designed. Then, the non-woven fabric was selected from the aspects of the fiber melting point and the non-woven fabric aperture, and the non-woven fabric covered with grass seeds was sealed with the "thermal bonding technology". The study found that when the spunlace nonwoven fabric with PP/HDPE (70%) and viscose fiber (30%) with a fiber fineness of 0.17 tex was selected, and the temperature of the heat sealing device was 120-130 ℃, the bonding place was smooth and even; After 30 days, the height of the tubular planting yarn and the directly planted seedlings were 100mm and 90mm, respectively. The design of the planting yarn processing equipment is significant. It has compact structure and it is feasible in design concept. Compared with ordinary grass seeds, the tubular planting yarn produced by planting yarn processing equipment has advantages in both growth height and growth speed. Therefore, the purpose of combining textile materials and structural design in landscape field is achieved. It provides a new idea for mass planting of lawn.
