Patented Mar. 30, i943 UNITED STATES PATENT OFFICE FLAT GOODS AND YARN THEREFOR Isaac .1. Davis, Swarthmore, and Edgar S. Kennedy, Wayne, Pa... assignors to American Viscose Corporation, Wilmington, Del., a corporation of Delaware No Drawing. Application October '18, 1940, Serial No. 361,728
Claims.
This invention relates to low denier high strength synthetic yarns and knit goods produced from said yarns. More particularly the invention relates to low denier high strength.
synthetic yarns and fiat knit goods such as full fashioned hosiery and the like produced from said yarns.
It has been found that flat knit goods producedfrom low denier synthetic yarns in the ordinary manner do not have suflicient elasticity with the result that articles of apparel formed therefrom do not retain their shape and do not fit satisfactorily. Also the operation of knitting such yarns on a flat knitting machine is accompanied and appended claims.
In carrying out this invention, any high strength synthetic yarn may be used that has a tensile strength when wet of from 1 to 4 or more grams per denier and an extensibility when dry of from 16 to 23%, including regenerated cellulose yarn made by the viscose process, cellulose acetate yarn and yarns made from resinous materials such as those known in the trade as Vinyon. Filaments or yarn or from to "75 denier are given a twist of from 60 to 25 turns per inch to form a single. The single is then knitted on a fiat knitting machine to form fabricsor other flat knit goods such as full fashioned hosiery. It is found that the fabric or goods knitted with this type of yarn shows an improved elasticity and resistance to snagging and abrasion. It is substantially dull in appearance as contrastedwith the bright or shiny appearance of ordinary flat knit goods. Also the twist in the yarn remains substantially uniform throughout the goods. Where heavier flat knit goods are desired, such as in the welt portion of full fashioned hosiery, a yarn may be used comprising two or more of the above singles that have been plied together. The ply twist is in a direction opposite tothe direction of twist in the singles and is less than the singles twist. The ply yarn may also be used in sewing'flat knit goods such as the back seam The following examples are'illustrative of the invention:
1. A- 25 denier, 12 filament regenerated cellulose yarn made by the viscose process having a wet strength of 2 grams per denier and a dry strength of 3. grams per denier is given'a twist of 50 turns per inch. The yarn is then knitted 'on a fiatknitting machine such as a full fashioned hosiery machine.
Y 2. A 40 denier, 19 filament regenerated cellulose yarn made by the viscose process having a wet strength of 2 grams per denier and a dry strength of 3 grams per denier isgiven a twist of 40 turns per inch. The yarn is then knitted on a flat knitting machine such as a full fashioned hosiery machine.
3. A 50 denier. 24 filament regenerated cellulose yarn made by the viscose process having a .wet strength 0132 grams per denier and a dry strength of 3 grams per denier is given a twist of 35 turns per inch. The yarn is then knitted on a flat knitting machine such as a full fashioned hosiery machine.
4. A '15 denier, 36 filament regenerated cellulose yarn made by the viscose process having a wet strength of 2 grams per denier and a dry strength of 3 grams per denier is given a twist of 25 turns per inch. The yarn is then knitted on a flat knitting machine such as a full fashioned hosiery machine.
5. Two yarn singles, madein accordance with Example 1, are given a twist of 20 turns per inchin a direction opposite to the direction of twist in the singles. knitting machine such as a full fashioned hosiery machine where a heavier] fabric is desired, for instance in the welt portion of the stocking.
6. A 50 denier, 24 filament regenerated cellulose yarn made by the viscose process having a wet strength of 2 grams per denier and a dry strength of 3 grams per denier is given a twist of 20 turns per inch. Three of these singles are then plied together with a twist of 22 turns per inch in a direction opposite to the direction of the singles twist.
back seam of full fashparting from the spirit and scope of the inven-,
tion as defined by the appended claims.
What we claim is:' 1. A low denier, high strength rege :erated cel- This yarn is knitted on a flat This yarn may be used insewing flat knit goods of either silk or synthetic lulose yarncomprising a multifllament single of from approximately 10 to 75 denier having a twist in inverse proportion to the denier of from approximately 60 to 25 turns per inch respectively, said filaments having a tensile strength when wet of at least from 1.5 to 4.5 grams per denier and an extensibility when dry of from 2. A low denier, high strength regenerated cellulose yarn comprising a plurality of multifilament' singles of from approximately 10 to 75 denier having a twist in inverse proportion to the denier of from approximately 60 to 25 turns per inch respectively, plied together in a direction opposite to the direction of twist in the singles, the ply twist being less than the singles twist. the said filaments having a tensile strength when wet of at least from 1.5 to 4.5 grams per denier and an extensibility when dry of from 16% to 23%.
high strength regenerated cellulose yarn comprising a multifilament single of from approximately 10 to 75 denier having a twist in inverse proportion to the denier of from approximately 60 to 25 turns per inch respectively, said filaments having a tensile strength when wet of at least from 1.5 to 4.5 grams per denier and an extensibility when dry of from 16% to 23%.
4. Flat knit goods comprising a low denier, high strength regenerated cellulose Yarn comprising a multifilament single of approximately 50 denier having a. twist of approximately 35 turns per inch, said filaments having a tensile strength when wet of at'least from 1.5 to 4.5
7. 20 3. Flat knit goods comprising a low denier,
grams per denier and an extensibility when dry of from 16% to 23%.
5. Flat knit goods comprising a low denier, high strength regenerated cellulose yarn comprising a plurality of multifilament singles of from approximately 10 to 75 denier having a twist in inverse proportion to the denier of from approximately 60 to 25 turns per inch respectiveiy, plied together in a direction opposite to the direction of twist in the singles, the ply twist being less than the singles twist, the said filaments having a tensile strength when wet of at least from 1.5 to 4.5 grams per denier and an extensibility when dry of from 16% to 23%.
