Studies on purchase behavior, washing and durability:Nursing bras

对哺乳胸罩的调查是由五年内经历过哺乳期的女性进行的。超过90%的人使用了护理胸罩，并评价了母乳喂养的便利性，但他们往往对设计和耐用性感到不满。在日常生活中，有时会有超过10g的母乳粘附在奶垫上，并且奶垫内湿度较大。从葡萄球菌的增殖研究来看，卫生巾最好在6小时内更换，以保持清洁卫生的环境。牛奶很难洗掉。使用碱性粉末状洗涤剂和洗涤前先浸泡在洗涤剂溶液中，都能有效去除牛奶残留。

The survey of nursing bras was conducted by the females who experienced lactation within five years. More than 90% used the nursing bras and evaluated ease of breast feeding, however they tended to feel dissatisfaction in design and durability.More than 10g breast milk was sometimes adhered to mammy pads in daily life and there was high-humidity within the pads. From the proliferation study of Staphylococcus, pads are desirable to be changed within six hours to keep clean hygienic environment. The milk is hard to be washed off. The use of alkalescent powdered type detergent and a soak in detergent solution before washing are effective to remove the residue of milk.
