摘要
Abstract
In this study,two small-molecule hydrophobic components,paraffin wax and alkyl ketene di-mer(AKD),were selected to prepare paraffin wax emulsion and AKD emulsion via emulsification.The ob-tained emulsions were applied to three types of knitted fabrics(cotton,nylon,and polyester)for waterproof fin-ishing through a pad-dry-cure process.Single-factor experiments were conducted to investigate the effects of emulsion dosage,emulsion blending,as well as catalyst type and dosage on the waterproof performance,contact angle,and breaking strength of the fabrics.The results showed that when the two blended small-mol-ecule hydrophobic emulsions were used at a dosage of 80 g/L,with 10%aluminum sulfate as the catalyst at a dosage of 12 g/L,all three fabrics achieved a waterproof rating of Grade 5 and contact angles greater than 120°.Color difference tests indicated that fabrics finished with AKD emulsion exhibited a greater color change than those finished with paraffin wax emulsion.Washing durability tests revealed that fabrics finished with AKD emulsion had a higher number of wash cycles than the same fabrics finished with paraffin wax emulsion.关键词
