This invention relates to a crimped lyocell tow for use in stretch breaking, worsted or semi worsted spinning, its manufacture and use.

Provided is a composite twist color fiber formed by joining polypropylene terephthalate (PPT) and cationic-dyeable polymer side by side. The polypropylene terephthalate (PPT) and the cationic-dyeable polymer differ in contraction rate, such that the composite fiber thus formed is not only helical but also extensible and contractile. Fabric made of the composite fiber is highly capable of elongating and retracting; hence, not only do finished products made of the fabric have low contraction rate, but surface of the fabric also exhibits satisfactory mixing tones.

The disclosure generally relates to bicomponent fibers, and more particularly, methods to make bicomponent fibers and articles comprising them, wherein a first extruded component has a moisture level less than a second extruded component. The bicomponent fibers may comprise polyesters and are useful in articles such as carpets and fabrics.

A nonwoven fabric. The nonwoven fabric can include a first surface and a second surface and a visually discernible pattern of three-dimensional features on one of the first or second surface. Each of the three-dimensional features can define a microzone comprising a first region and a second region. The first and second regions can have a difference in values for an intensive property, wherein the intensive property is one or more of thickness, basis weight, or volumetric density, and wherein the first surface has a TS7 value different than a TS7 value of the second surface.

A nonwoven fabric layered body includes a first nonwoven fabric layer including a crimped fiber (A), which is a fiber made of a thermoplastic polymer and which has an average crimp diameter of 800 μm or less; and a hydrophilic agent.

A stretch yarn includes a multifilament including fibers having a coiled crimping form in a fiber axial direction, wherein a coil diameter distribution of crimping in the fiber has two or more groups, a ratio of a maximum group average value to a minimum group average value of the coil diameter (a maximum group average value/a minimum group average value) is less than 3.00, and a cross section of the fibers constituting the multifilament is an eccentric core-sheath cross section.

This long-fiber woven fabric comprises long fibers formed by two-component conjugate spinning from poly(ethylene terephthalate) and a copolyester, and has an apparent density of 0.1-0.25 g/cc and a recovery from 50% elongation of 55% or greater.
