Elastic thread lines can extend along borders of puckering areas of a fabric. The thread lines can include elastic thread line sections of the thread lines passing through thread line intersections and segments of the thread lines between the intersections. The elastic thread lines can bias the puckering areas in multiple different non-parallel directions toward a puckered configuration. In the puckered configuration, the puckering areas can be gathered together to pucker the fabric. The fabric can be stitched together to form a product, such as a sleeping bag sack that is stretchable in multiple orthogonal directions by stretching the thread lines. Elastic thread line sections passing through intersections can be made more secure by forming thread line section patterns that increase numbers of thread line crossings at the intersections. Densities of thread lines in different directions can be selected to produce different amounts of gathering, and for security.

Flame resistant fabrics formed with a combination of body yarns and stretch yarns that exhibit excellent physical and thermal properties. The body yarns are formed at least in part with flame resistant materials. The stretch yarns are corespun yarns having an elastic core surrounded by a fiber sheath formed at least in part with flame resistant materials. The fiber sheath protects the elastic core from direct exposure to heat and flame that would otherwise cause the core to degrade or melt.

Wool fabrics are disclosed that have improved stretch properties. The wool fabrics can be used in numerous and diverse applications, such as to make uniforms. The fabric can be designed to have greater than 15%, such as greater than about 20% stretch in one or more directions, such as in the fill direction. In one aspect, longer wool fibers are used in the fabric in order to increase durability.

Provided is a compression garment formed of a stretchable woven fabric with a uniform elasticity, such as denim. A circumferential portion of the garment surrounds a wearer's body part and is characterized by different degree of stretching but the same circumferential compressive forces when worn by a wearer, at various axial locations due to geometric cuts made to the fabric to form one or more fabric panels, each of which extend along the entire length of the circumferential portion. The compressive forces, degrees of stretching and circumferential lengths of fabric, are calculated using formulas and algorithms that take into account various factors relating to the fabric and the garment being formed.

A method of loading a carding machine for the manufacture of yarn. The method includes deriving a component load schedule with a plurality of discrete loading steps. The series of discrete loading steps comprise at least a first load amount and a second load amount, wherein the sum of the first load amount and the second load amount is a first overall load amount. The method includes loading a first amount of a first component equal to the first load amount of a discrete loading step, loading a second amount of a second component equal to the second load amount of the discrete loading step and repeating the steps of loading a first amount and loading a second amount for each of the discrete loading steps.

A filamentary core for an elastic composite yarn, particularly for an elastic textile composite yarn, comprising at least two elastic performance filaments, wherein each of the at least two elastic performance filaments is capable of being stretched at least about 2 times its package length and has at least 90% up to 100% elastic recovery after having being released from a stretching 2 times its package length.
