Abstract
Abstract A process for storing freshly extruded textile filaments for subsequent use in a textile process which comprises: spinning a fiber-forming polymer into a filament, delivering the filament to a circular one end or one-cut circular knitting machine, knitting the filament into a continuous tubular knitted article, delivering this knitted article into a storage container and cutting the knitted article when the container is full.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
121 words
A process for manufacturing textile filaments from a polymer comprising the steps of: spinning the polymer into a filament yarn; delivering the filament yarn to a circular one-cut knitting machine immediately after spinning; knitting the filament yarn into a continuous nonrotating tubular structure; advancing the knitted structure into a storage container; cutting the knitted structure after a pre-determined amount of structure has accumulated; stabilizing the filament yarn in the knitted structure while the knitted structure is in the storage container by atmospherically aging the knitted structure; and then deknitting the filament yarn accumulated in the knitted structure to remove the slight twist imparted to the filament yarn during knitting of the filament yarn, thus producing zero twist yarn for further processing.
Claim 2
Dependent Claim
121 words

Claim 3
Dependent Claim
28 words
The process of claim 1, wherein the knitted structure is washed subsequent to advancing the knitted structure into the storage container and prior to deknitting the knitted structure.
Claim 4
Dependent Claim
28 words
The process of claim 1, wherein the knitted structure is sized subsequent to advancing the knitted structure into the storage container and prior to deknitting the knitted structure.
Claim 5
Dependent Claim
19 words
The process of claim 1, wherein the filament yarn is produced from the polymer by melt spinning the polymer.
Claim 6
Dependent Claim
15 words
The process of claim 1, wherein the filament yarn consists of a plurality of strands.
Claim 7
Dependent Claim
27 words
The process of claim 5, wherein the filament yarn is drawn after deknitting and wherein each strand of the filament is thereafter wound on a separate bobbin.
