Provided is a spunbond nonwoven fabric for use in filters which has excellent rigidity, folding endurance, and uniformity of a weight per unit area, and which also has excellent dust collection performance and mechanical properties. The spunbond nonwoven fabric for use in filters includes a thermoplastic continuous filament and has a partially fused portion. The nonwoven fabric has a stiffness of 2 mN or more and 100 mN or less, a weight per unit area-CV value of 5% or less, and a weight per unit area of 150 g/m.sup.2 or more and 300 g/m.sup.2 or less.

Disclosed is a method for manufacturing a shock-absorbing lanyard for easy length adjustment of partially oriented yarn (POY). The method for manufacturing a shock-absorbing lanyard for easy length adjustment of POY according to the present disclosure includes (a) weaving a safety tube band which is a tube fabric woven using fiber yarn and rubber yarn, and placing a core material in the safety tube band at the same time, wherein the core material is made of a plurality of POY and stretches in a longitudinal direction to absorb shock; (b) adjusting a length of the core material after weaving the safety tube band; and (c) combining the safety tube band with the core material to form a combination.

A multilayer fabric includes a first fabric and a second fabric superimposed onto each other. The first fabric is a non-woven fabric comprising a plurality of crimped filaments, the crimped filaments including a plurality of crimps. The first and second fabrics are constrained to each other at a plurality of constraining points or zones, wherein the surface of the second fabric has an area greater than the area of the first fabric. At least one portion of the second fabric disposed between adjacent constraining points or zones, has a plurality of bulgy zones, the bulgy zones protruding outward from the surface of the multilayer fabric.

A knit fabric includes a back layer including a first back yarn, the first back yarn having a minimum moisture regain of at least 6.0 weight percent. The first back yarn is plated with a back elastic yarn. The knit fabric also includes a face layer including a first face yarn having a maximum moisture regain of less than 5.5 weight percent. The first face yarn is plated with a face elastic yarn. The knit fabric further includes a connecting elastic yarn forming yarn connections between the face layer and the back layer binding together the layers. A denier of the face elastic yarn may be greater than a denier of the back elastic yarn and the connecting elastic yarn. One or both of the back layer or the face layer may comprise a full-feeder knit construction.
