For most purposes dedicated "Silk" or "Woolens" cycles beat just one hand wash.
Both fabrics are ones likely to be washed but require very different treatment in terms of water temp, mechanical action, cycle length, etc....
Many other things once covered by generic hand wash cycles (curtains, lace bed/table linens, etc..), can either have dedicated cycles, or one can modify certain others to suit with some machines.
In healthcare a sluice washer will have a suds container with decent sized holes to allow better draining/removal of solid matter (feces, vomit, etc...). They usually don't have door boots, drain pumps or other things were such matter can collect and be reintroduced during subsequent cycles.
Sluicing via machine is meant to replace old practice for healthcare laundry, diapers, and so forth of rinsing by hand to remove solid matter before things went to the wash.
Notice in video diapers are loaded into washer waste and all:
Difference between a "pre-wash" or "pre-rinse" is mainly water level; former is low while latter high. For sluicing and or to promote optimal debris removal you want high water level. OTOH for stain treatment/pre-washing you want basically same water level as wash cycles.
