Pack Life

Package Build

A general term that applies to the shape angles tension etc. of a yarn package during winding. Package build affects performance during subsequent processing.

Package dyeing

A method of dyeing in which the liquor is circulated radially through a wound package.
Note: Wound packages include stubbing in top form and cheeses or cones of yarn. (See also beam dyeing.)

Packages

A large selection of forms for winding yarn is available to meet the requirements of existing machinery and a variety of package builds is used to ensure suitable unwinding in later stages of manufacturing. Since a package with flanges cannot be unwound easily and quickly by pulling the yarn off overend most packages are flangeless with self-supporting edges. Some can be unwound at speeds up to 1500 yd/min. The accompanying diagram shows six common types of yarn packages.

Pad

Padding mangle

A form of mangle for the impregnation of textiles in open width in which the textile is passed through one or more nips. The textile may be saturated before passing through the nip, as in slop padding, or the impregnating liquid may be carried as a film on the surface of one of the bowls forming the nip and transferred to the textile as it passes through the nip, as in nip padding.

Padding thread

Additional warp or weft used in a fabric for the purposes of increasing its weight, bulk, firmness, or the prominence of the design. These threads are not visible on the fabric face.

Paddle Dyeing Machine
