Layered yarn and weighted blanket for deep pressure therapy

A weighted blanket comprising:

• a length of layered yarn arranged to form a weighted material having loops in an interlooped pattern, the weighted material having a top side and a bottom side, the length of layered yarn comprising:
• an outer tube comprising a length and an inner tubular wall defining a conduit extending longitudinally therethrough;
• and
• a fiber material comprising a plurality of spun fibers arranged within the conduit, each spun fiber of the plurality of spun fibers arranged in a substantially longitudinal direction uninterrupted within the conduit,
• wherein at least one of the plurality of spun fibers is attached along a longitudinal region of the inner tubular wall such that the at least one of the plurality of spun fibers is retained in a fixed positional relationship relative to the outer tube during and subsequent to interlooping of the length of the layered yarn,
• wherein the interlooped pattern is a single layer of interlooped yarn including knots at cross-sections of the loops and openings between the loops, the openings configured to allow airflow between the top side and the bottom side for providing breathability.

• an outer tube extending from a first end to a second end, the outer tube comprising an inner tubular wall defining a conduit extending longitudinally therethrough from the first end to the second end;
• and
• a plurality of lengths of material arranged within the conduit, each length of material of the plurality of lengths of material comprising a spun fiber, wherein the spun fiber is arranged in a substantially longitudinal direction uninterrupted between the first end and the second end,
• wherein at least one of the plurality of lengths of material is attached along a longitudinal region of the inner tubular wall such that the at least one of the lengths of material fibers is retained in a fixed positional relationship relative to the outer tube during and subsequent to interlooping of the length of the layered yarn,
• wherein the interlooped pattern includes openings where the length of layered yarn crosses other lengths of layered yarn, the openings configured to allow airflow between the top side and the bottom side thereby providing breathability,
• wherein the length of layered yarn has a substantially homogenous weight and density along the length of the outer tube.
