RE292877, Jul 5, 1977

Filed:

Feb 13, 1976

Appl. No.:

5/658063

Inventors:

Walter F. Illman - Greensboro NC
Robert C. Malpass - High Point NC
Delano M. Conklin - Burlington NC

Assignee:

Burlington Industries, Inc. - Greensboro NC

International Classification:

D06C 2900

US Classification:

28178

Abstract:

A compact apparatus and method for applying hot-melt size in a properly fluid state to a plurality of textile yarns. The apparatus comprises an internally heated rotating cylinder made of heat-conducting material, with deep grooves formed around it, one groove for each yarn strand. The size is preferably applied by urging a block of solid size against the grooves of the hot cylinder. From the point of application the molten size is carried by the rotation of the cylinder to a zone where each moving yarn strand passes briefly through a corresponding size-filled groove, essentially tangentially to the cylinder, and then moves away coated with an optimum amount of size. The method of application is unique in its capacity for placing a quick-setting, high molecular weight, film-forming melt size on yarn at high speed.

US Classification:

Abstract:

An apparatus and method effect application of molten size to textile yarns, such as spun yarns. An applicator cylinder is rotatable about a horizontal axis and has a number of grooves circumferentially formed in its surface, with peaked lands between the grooves, each land making an angle of about 8. degree. -12. degree. with respect to a plane bridging the top of an associated groove. A furnisher roll, also rotatable about a horizontal axis, picks up molten size from an open-top trough and delivers it to grooves in the rotating applicator cylinder. The surface of the furnisher roll cooperates with that of the applicator cylinder so that sloping areas of the furnisher roll mate with the lands of the applicator cylinder and so that flat areas of the furnisher roll bridge the entrances to the grooves. The furnisher roll may be of polytetrafluoroethylene machined to correspond to the surface of the applicator cylinder, or may have an elastomeric material surface. A cleaning device comprises a pad, which may be a thermoplastic polymeric material capable of lengthy exposure to high temperatures, having a surface corresponding essentially identically to the surface of the applicator cylinder, and mounted so that it is pressed into engagement with the applicator cylinder to remove molten size and contaminants from the grooves of the applicator cylinder.

International Classification:

C08K 505
C08K 510
C08K 513
C08L 6702

US Classification:

428253

Abstract:

A non-aqueous, water-soluble, quick-setting sizing composition suitable for application in the molten state to textile yarns of both continuous-filament and staple types, and for later removal by aqueous means, comprising a combination of a film-forming thermoplastic polymer with a melt-miscible viscosity reducer and solidification promoter, and yarns so sized. The polymer protects and consolidates the yarn, while its companion component promotes the even application and particularly the quick set-up of the molten size. Optionally, if desired, water-soluble lubricants may also be added to increase the lubricity and flexibility of the sized yarn.
