Abstract
Abstract A textured yarn is tensioned sufficiently to stabilize the yarn but insufficiently to remove the texture and is wound at a low tension to form a soft package on a collapsible package support. The yarn package is then dyed at an elevated temperature.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
113 words
In a continuous process for texturing then winding yarn on a package support that includes the steps of overfeeding a feed yarn through an air texturing jet with the resultant formation of texture-giving loops and winding the textured yarn on the package support under sufficient tension to stabilize the yarn without eliminating the loops and form a package of yarn, the improvement comprising: stretching the textured yarn between the texturing and winding steps, the degree of stretch being sufficient to stabilize the yarn without eliminating the loops; and winding the yarn under relatively low constant tension less than about 0.04 gram per denier to form a package of yarn suitable for package dyeing.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
89 words
A process for dyeing a yarn package comprising the continuous steps of overfeeding a feed yarn through an air texturing jet with the resultant formation of texture-giving loops; stretching the textured yarn to stabilize the yarn without eliminating the loops; winding the textured yarn under relatively low constant tension less than about 0.04 gram per denier into a package on a collapsible package support to form a package of yarn; and the separate step of dyeing the package at an elevated temperature of from about 60*C. to about 130*C.
