Cotton fabrics for the standard artificial soiling recommended by JOCS are used for the treatment under conventional industrial conditions. Their properties, however, are different markedly from lot to lot owing to the finishing conditions. Accordingly, authors investigated the quality change of the fabrics during oxidative bleaching by sodium hypochlolite solution. The change of copper number and average polymerization degree (fluidity), as well as the tensile and tear strength of bleached fabrics were determined.Results obtained are as follows : 1) With the increases in copper number and/or fluidity of oxidized cellulose, the fabrics become to be easily soiled and the artificially soiled fabrics are easily desoiled as well.2) Copper number and fluidity of oxidized cellulose are intimately related to the tear and tensile strength. Chemical damage of the fabrics caused by bleaching can also be detected from these measurements.The authors found a clue to control the bleaching condition in order to supply standard cotton fabrics of constant properties.

Cotton and 50/50 polyester/cotton fabrics, untreated and with four formaldehyde crosslinking treatments and two resin finishes, were soiled with oily and nonoily soils and an oily stain. Extent of soiling, ease of soil and stain removal, and the development of yellowness were determined after repeated laundering in a Launder-Ometer. Soiling and soil removal were influenced more by type of soil, fiber content, process of producing crosslinks, and catalyst than by the chemical composition of the crosslinking agent, although chemical composition did produce some effects. Development of yellowness of untreated and crosslinked fabrics during laundering was attributed to swelling of cotton fiber and cotton content of polyester/cotton blend fabrics. Cross-linking of cotton and cotton/ polyester fabrics by a pad-dry-cure process retarded the development of yellowness. Yellowness developed in both oily and nonoily soiled fabrics. Yellowness was not related to amount of soil on the fabrics.
