由表1可知，采用本发明制备的实施例1-4的人造草坪样品，渗水率远大于市售的人造草坪样品，这是由于采用本发明的制备方法制备的人造草坪100，经线丝11的横截面呈扁平形结构，纬线丝12中的第一丝线横截面呈圆形结构， 经线丝11和纬线丝12通过编织机编织后相互交错形成基布1时，基布1涂覆胶黏剂后通过吹气装置时，吹气装置吹出的气流将基布1上的针孔13内的部分胶黏剂吹出，粘结层3通过针孔13吹出的气流形成有与针孔13相连通的透水孔14，人造草坪100通过透水孔14的渗水使得渗水率提高，采用本发明制备的人造草坪100无需通过扎孔装置对基布1的涂胶面进行扎孔，避免了扎孔对人造草坪100结构的破坏，可以有效防止人造草丝2松动并脱落，提高人造草坪100的使用寿命。
以上述依据本发明的理想实施例为启示，通过上述的说明内容，相关的工作人员完全可以在不偏离本发明的范围内，进行多样的变更以及修改，本项发明的技术范围并不局限于说明书上的内容，必须要根据权利要求范围来确定其技术性范围。
