Abstract:

In order to improve water repellency of polypropylene (PP) nonwoven fabric and investigate the influence of bagging microenvironment on growth situation, PP nonwoven fabric with water repellent finishing was prepared using the waterborne polyurethane as crosslinking agent in combination with fluorine based water repellent agent. By orthogonal experiments analysis, the influence of water repellent concentration, crosslinking agent concentration, soaking time and curing temperature on water-repellency, ventilation property and light transmittance fwere studied and the optimal finishing process was obtained. By bagging experiment for grape in the fields, the light intensity,temperature and humidity of grape fruit bag were measured inside and outside, and the influence of PP nonwoven bags of water repellent finishing of fruit microenvironment on grape fruit quality were investigated. The results show that the primary and secondary factors and the optimal processing of water repellent finishing are curing at 130℃, water repellent concentration of 40g/L, soaking time of 10 min and crosslinking agent of 3 g/L.Water repellent performance of the PP non-woven grape bag increased by 60%.
