摘要
将棉质半成品水刺非织造布浸渍于不同质量分数的废蚕丝制成的丝胶溶液中,通过二浸二轧工艺烘干定型,实现了可降解棉质非织造地膜的制备。通过灰色关联分析得出影响地膜强度的因素及其排序为:回潮率>增重率>丝胶质量分数;采用ESEM、红外光谱、降解率等方法进行理化性能表征,分析其降解前后性能差异。结果表明:浸渍涂层法中胶液质量分数为1%时,其理化性能最佳,纵横向断裂强力分别为33 N、44 N,回潮率为10.8%。
The hydroentangled semi-finished cot different mass concentration, followed by double degradable cotton nonwoven mulching membrane. ton nonwoven fabric was impregnated in sericin solution with -dip-double-nip process, then dried and set, thus obtained a It was found through gray correlation analysis that the factors influencing the strength of the mulching membrane fell into the following order： moisture regain 〉 weighting percentage 〉 sericin mass concentration. The product was characterized by using scanning electron microscope （SEM）, Fourier transform infrared spectroscopy （VFIR） and degrade efficiency. The preliminary results indicated that the best physical property of the fabric is obtained when impregnated in 1% mass concentration sericin solution, whose lengthwise and crosswise breaking strength are 33 N and 44 N respectively, and the moisture regain, 10.8 %.
