Melting, charring or weld spatter of any part of the sling. Thus, most continuous processes conventionally used are provided with one. The pH was adjusted with sulfuric acid to between 6 and 7. Although neither the QC Labs or the customer could determine exactly how or to what chemical the harness had been exposed, QC Labs was able to narrow it down to some type of acid. This is related to the initial question re yellowing of fabrics, which I am desperate to learn more about. Wood contains much more lignin than cotton or flax, and wood pulp papers especially are much more sensitive to residual or environmental acids and oxidative decomposition than cotton. There are other dye removing chemicals that are safe to use with nylon, however.

I bet this dye remover works pretty good though Portion of each dried sample and a piece of untreated fabric were tested for warp tensile by the strip method using a Scott Tensile Tester ASTM method and the results recorded as Initial. This degradation, as in the case of materials exposed to sunlight and repeated weathering, manifests itself through the discoloration of the nylon material and its loss in tensile strength. Batch Biotreatment After being filtered, the mycelial mass was inoculated in the effluent according to the conditions shown in Table 2. Portions of the samples were tested for warp strip tensile strength and recorded as initial. Textile finishing resin, wrinkle resistant cellulose textile, processes of making resin and treated textile.
Comparison was made with a cover which had not been so treated. Nylon fabric similar to that employed in the preceding examples and having a brightness of Effluent and Reactor The E1 effluent was obtained from a kraft pulp and paper mill. Bleaching can be effected by contacting the nylon material with the aqueous medium containing the dissolved peroxygen compound and aliphatic carboxylic acid in any desired manner. Table 1 Strip Tensile Strength in lbs. Its mycelial mass, which was not pelletized, was used in batch experiments to treat the same effluent.
Get updates Get updates. Peracetic acid has a pH of about 1. I bet this dye remover works pretty good though Nara Saho Jyogakuin Junior College. Substantially no loss in fiber strength resulted and the final brightness was The peroxygen compound may be employed in any desired amount, a concentration in the bleaching medium equal to from about 0.
