Aspects herein relate to a knit textile or garment that comprises at least a first and second portion. The first portion comprises a first percentage by weight of a first yarn and a second yarn. The second portion comprises a second percentage by weight of the first yarn and the second yarn. The two portions are integrally knitted from each other. The second portions provide a high level of air permeability, while the first portions provide moisture wicking and may be used as modesty portions in garments.

A webbing for use with a tiedown or sling which has overall increase strength efficiency when compared to known tiedowns or slings which use texturized yarn. The webbing contains non-texturized yarn material having reduced elongation characteristics in the core, combined with non-texturized yarn having higher elongation and improved wear characteristics on the exterior surfaces.

Aspects herein provide for a knit component having a tubular rib knit structure that extends away from a base portion of the knit component. The tubular rib knit structure includes at least a first portion extending along a longitudinal side of the tubular rib knit structure, where the first portion exhibits a first visual effect at a first area of the knit component and exhibits a second visual effect at a second area of the knit component.

A preparation method of self-crimping elastic combined filament yarns for knitting is disclosed, wherein the combined filament yarns are extruded from the same spinneret; a first fiber-forming polymer melt is divided into two ways, one is directly extruded after distribution; and the other is extruded after distribution by side-by-side composite spinning together with a second fiber-forming polymer melt; the first fiber-forming polymer and the second fiber-forming polymer are compatible or partially compatible; on the same spinneret, a ratio of the number of spinneret holes m for direct extrusion to the number of spinneret holes n for extrusion after distribution by side-by-side composite spinning is 1:(5-10); the self-crimping elastic combined filament yarns for knitting are prepared according to specific spinning processes, wherein the combined filament yarn mainly comprises a first fiber-forming polymer monofilament and a first/second fiber-forming polymer side-by-side composite monofilament; wherein the monofilament crimping directions are randomly distributed.

A type of side-by-side self-crimping elastic fiber and preparation method thereof are disclosed. The preparation method includes distributing compatible or partially compatible first fiber-forming polymer melts and second fiber-forming polymer melts, then the fiber is extruded from first spinneret holes and second spinneret holes on the same spinneret. The first fiber-forming polymer melts and the second fiber-forming polymer melts flow into the first spinneret holes through first and second distribution holes, and flow into the second spinneret holes through third and fourth distribution holes, wherein the four distribution holes are cylindrical holes of equal height, the ratio of the diameter of the first distribution holes to the diameter of the second distribution holes is (1.10-1.20):1, and the ratio of the diameter of the third distribution holes to the diameter of the fourth distribution holes is 1:(1.10-1.20).

The present disclosure provides an airbag patch cloth that has superior packability and cutting resistance upon deployment of the airbag, and which is particularly suitable for a curtain airbag. The airbag patch cloth is a woven fabric which satisfies the following equations: P.sub.x=E/(T.sub.x×F.sub.x)×1000, P.sub.y=E/(T.sub.y×F.sub.y)×1000, wherein E indicates the kinetic energy (J) of a block and a blade. In the equations, T.sub.x indicates the average value (mm) of a torn length in the warp direction, F.sub.x indicates the linear density (dtex) of the warp constituting the fabric, T.sub.y indicates the average value (mm) of a torn length in the weft direction, and F.sub.y indicates the linear density (dtex) of the weft constituting the fabric. At least one of dynamic tear characteristics P.sub.x and P.sub.y is greater than or equal to 0.8.

The present invention discloses a hemming-stitch-free warp-knitted elastic fabric and a method for knitting thereof. The method includes: making a non-elastic yarn pass across a guide needle of the first guide bar and form the surface of the fabric by knitting via two needles or three needles in a 1×1 or 2×1 warp plain stitch loop mode, and making an elastic yarn pass across a guide needle of the second guide bar and form the inside of the fabric by knitting with the aforementioned non-elastic yarn in the same direction via three needles in a open double warp plain stitch loop mode, and two loops are continuously formed on each course of the open double warp plain stitch loop. The hemming-stitch-free warp-knitted fabric produced according to the present invention has good snagging grade, moderate horizontal straight tensile force and good resilience.

A cloth for mattress including a knitted fabric that is knitted from blended yarns contains flame retardant rayon fibers, modacrylic fibers, polyimide fibers, and low-melting polyester fibers. The cloth for mattress can be obtained by producing blended yarns containing the flame retardant rayon fibers, the modacrylic fibers, the polyimide fibers, and the low-melting polyester fibers, and producing a knitted fabric by knitting the blended yarns. The cloth for mattress has excellent flame retardancy, ensures easy handling when used to cover a mattress, is resistant to pilling without reducing the strength of the blended yarns, and is also safe for contact with the human body.
