I have run into the term "Rachel (or Raschel) knitting" in translations having to do with textiles, so perhaps that would fit your context.

Here are some references:

Deluxe extra heavyweight ***rachel knit*** thermal of 50% Cotton/50% Polyester traps and retains body heat for maximum warmth. Originally developed for the military! Reinforced flat seam construction for smooth fit and extra strength. Shrinkage controlled for lasting size and shape.

Knitting uses hooked needles to interloop
yarns, forming stretchy fabrics. Hand knitting
uses a single set of needles. Home or manufacturing
machines used in knitting use multiple
needles to form either warp knit and/or filling
knit fabrics. Loops in the direction of the fabric
selvage (length) are called wales, while crosswise
rows of loops are called courses. Gauge
describes the fineness of the knit stitch. Warp
and double knit fabrics stretch less and do not
unravel or run as easily as filling or jersey
knits. ***Raschel knit is used to form lace-like
fabrics. However, if snagged, damage is
potentially greater in raschel knit fabrics than
in true lace, which is knotted.****

Raschel Knit

Hope it helps. :-)

"Dentelle Rachel" exists in specialized French vocabulary, with the meaning explained by the brilliant answer above (both a knitting technique on specific machines and the resulting faabric):
