Mechanical action in the laundry happens in two places, the wash wheel and the dryer.
Good washing combines proper chemicals with proper mechanical action to remove and suspend soil. In the wash wheel, water acts as a lubricant and as a shock absorber helping to reduce friction between fibers as the garments are tumbled during the wash cycle. For this reason it is important that drain times are kept to a minimum, reducing the chance for mechanical wear to the garments being tumbled in a waterless wash wheel. The lint that is created in the washing process either goes down the drain with the soil or sticks to the surface of the fabric until the next step in processing causes it to leave.
Dryers offer the greatest potential for mechanical wear on the fibers. There is nothing to cushion the fall or lubricate the fibers of the garments as the water does in the wash wheel. It is just fabric against fabric and fabric against metal. Abrasion, friction and impact combine to wear away the fibers creating lint. The lint produced here either goes up the exhaust stack to the filter or it will lie on the surface of the garment.
Bypassing the dryer and processing the garments damp-to-dry through the tunnel finisher will reduce the amount of lint and prolong the life of the garments.

When servicing a single 1,000 room hotel about $50,000 worth of delivery hampers are required. Hamper cost to service the largest Las Vegas properties could cost $400,000! How do you decide which hampers to purchase? There are several basic questions that need to be addressed. 1. What size hamper (P72 or BLT72 being the most common). 2. … [Read More...]
Text book definition: The probability that a particular piece of equipment will come on at the time of the facility's peak load. It is the ratio of the sum of the individual non-coincident maximum demands of various subdivisions of the system to the maximum demand of the complete system. The diversity factor is always greater than 1. The (unofficial) … [Read More...]
For any heat exchanger to approach 100% exchange efficiency it must be in a COUNTER-flow condition. The Maximum exchange efficiency while in a CO-flow state is 50%. Most shell & tube exchangers have a reversing valve. A correctly operating reversing valve takes the flow out of COUNTER-flow & places it into a CO-flow condition. The OEM’s … [Read More...]
Readers question: In a recent Hot Tip you were talking about boilers and you used the term BHP to describe the size of the boiler. Why use the “B” to describe Horsepower? There are several different measure of power where the term “horsepower” is commonly used. The following conversion chart should help. Horsepower conversions: In certain … [Read More...]
Readers question: “In a recent Hot Tip, it was recommended that all new washroom trenches be poured monolithically, was does that mean?” Monolithic means it is made from a single pour of concrete. Usually when the term monolithic is used, it is because the concrete footings and slab are poured at the same time. Sometimes footings are poured separately, … [Read More...]
