How Laundering Affects Clothes.

After thirty washings with hard Soap, soda, sodium silicate and perborate, respectively, linen and cotton textiles showed higher strength values with hard water than with soft water. With soft water sodium silicate showed a distinct injurious action on cotton and perborate was still more harmful. Goods washed with soap improve to luster and show a brilliant white color by reflected light; goods washed In soda show a strong yellow in transmitted light with a slight shade of pink; by reflected light they appear slightly gray. After washing with silicate the goods are white but quite without luster, being dull and chalky.
