WHAT IS TUNNEL BLEACHING?
History of Tunnel Bleaching

Tunnel Washers entered the laundry market in the 1960's. They were introduced to save water, energy, and labor. They did this to some degree.

There are two types of tunnels currently being used for Bleaching socks in 1992, when the late Don Haselden of Adams Millis was looking for a better way to extract socks. The initial interest was in the press which had been used in conjunction with the tunnel in the laundry industry since the '60s. Don's trials using the press to extract led him to the question: Why can't we use the tunnel to perform the bleaching process?

Lab tests were run to determine if the peroxide bleaching technology used in the continuous system for piece goods could be charged enough to give an adequate white in the allotted time. The shade was found to be acceptable for certain standards in the market. This left the concern of rinsing; the time frame would be 16 minutes to rinse and apply softener.

Past experience showed that KOH was much freer rinsing than NaOH, so KOH has been used for the alkali in these systems since their conception. The systems still use as much as four gallons of water per pound for rinsing as well as incorporating an acid in the softener to neutralize the goods.
