摘　　要：为了研究热熔胶用于针织服装接缝的力学性能,以乙烯-醋酸乙烯酯(EVA)树脂、C5石油树脂和氢化C9石油树脂为主要原料制备胶样,并将胶样用于针织面料接缝,测试胶样的黏度、力学性能以及用于针织面料后的接缝强力、弹性回复率和耐水性。研究结果表明:C5石油树脂和氢化C9石油树脂配比含量是影响胶样熔融黏度以及力学性能的重要因素,其配比含量的增加会导致熔融黏度下降;温度环境对于力学性能的影响较大,胶样在75℃高温条件下软化变形,不具备力学性能;热熔工艺参数会对针织面料接缝强力造成影响,但是对弹性回复率以及热缩率的影响可忽略不计。在定伸长率为50%的条件下,弹性回复率为97.64%~98.69%,热缩率范围均在-1.31%~-0.21%之间,符合标准热缩率范围;具备较好的耐水性,经过7次水洗测试后,针织面料没有出现脱胶现象。In order to study the mechanical properties of hot melt adhesive used in knitted garment seams,the adhesive samples were prepared with ethylene-vinyl acetate(EVA)resin,C5 petroleum resin and hydrogenated C9 petroleum resin as the main raw materials.The adhesive samples were used in knitted garment seams,and the viscosity,mechanical properties of the adhesive samples,as well as the seam strength,elastic recovery rate and water resistance after used in knitted garment were tested.The research results showed that the proportion content of C5 petroleum resin and hydrogenated C9 petroleum resin was an important factor affecting the melt viscosity and mechanical properties of the adhesive samples,and the increase of the proportion content would lead to the decrease of melt viscosity.The temperature environment had a great influence on the mechanical properties,and the adhesive sample did not have mechanical properties due to its softening deformation under the high temperature of 75℃.The hot-melt process parameters would affect the seam strength of knitted garment,but the effect on elastic recovery rate and thermal shrinkage rate could be ignored.Under the condition of constant elongation rate of 50%,the elastic recovery rate was 97.64%-98.69%,and the thermal shrinkage rate range was-1.31%to-0.21%,which met the standard thermal shrinkage rate range.It had good water resistance.After 7 times of washing test,the knitted garment did not have degumming phenomenon.
