Method of manufacturing elastic fabric

Claim 1

THE METHOD OF MAKING AN ELASTIC TEXTILE FABRIC WHICH AFTER PROCESSING HAS A PREDETERMINED CLOSENESS OF CONSTRUCTION, DIMENSIONAL STABILITY AND STRETCH, WHICH METHOD COMPRISES FIRST CONSTRUCTION A DIMENSIONALLY UNSTABLE INITIAL TEXTILE FABRIC HAVING AN INITIAL LENGTH L1 OF ANY GIVEN PIECE WHEN RELAXED, GREATER THAN LC OF SAID GIVEN PIECE AFTER PROCESSING, SAID INITIAL FABRIC COMPRISING AN UPPER SERIES OF PICKS AND A LOWER SERIES OF PICKS, A PLURALITY OF INELASTIC WARP THREADS AT LEAST SOME OF WHICH ARE INTERWOVEN WITH AT LEAST SOME UPPER AND SOME LOWER PICKS, AND A PLURALITY OF ELASTIC WARP CORE THREADS EACH HAVING A TIGHT INELASTIC SPIRALLY WOUND COVER THEREON. SAID INITIAL FABRIC HAVING AN INITIAL CLOSENESS OF CONSTRUCTION WHICH IS LESS THAN THAT OF THE FABRIC AFTER PROCESSING BY THE PERCENTAGE C, WHERE C IS SUBSTANTIALLY THE NORMAL WASH SHRINKAGE OF THE INITIAL FABRIC, AND, AN INITIAL STRETCH S1 WHICH IS LESS THAN THE FINAL STRETCH SC OF THE FABRIC AFTER PROCESSING WHEREIN S1 IS DETERMINED BY THE FORMULA: S1=SC(1-C/100)-B S1, SC AND C BEING EXPRESSED IN PERCENTAGES, AND MECHANICALLY COMPACTING SAID FABRIC LENGTHWISE BY C PERCNET OF L1 TO A LENGTH OF LC, THE MECHANICAL COMPACTION CHANGING THE ANGLE OF THE SPIRAL COVER OF THE COMPOSITE WARP CORE THREADS TO REDUCE THE GRIP ON THE ELASTIC CORE THREADS THEREOF AND INCREASING THE CLOSENESS OF CONSTRUCTION TO THEREBY PROVIDE INCREASED LONGITUDINAL STRETCH IN THE FABRIC OVER THAT NORMALLY EXPECTED.

Claim 2

THE METHOD OF MAKING AN ELASTIC TEXTILE FABRIC WHICH AFTER PROCESSING HAS A PREDETERMINED CLOSENESS OF CONSTRUCTION, DIMENSIONAL STABILITY AND STRETCH, WHICH METHOD COMPRISES FIRST CONSTRUCTION A DIMENSIONALLY UNSTABLE INITIAL TEXTILE FABRIC HAVING AN INITIAL LENGTH L1 OF ANY GIVEN PIECE WHEN RELAXED, GREATER THAN LC OF SAID GIVEN PIECE AFTER PROCESSING, SAID INITIAL FABRIC COMPRISING AN UPPER SERIES OF PICKS AND A LOWER SERIES OF PICKS, A PLURALITY OF INELASTIC WARP THREADS AT LEAST SOME OF WHICH ARE INTERWOVEN WITH AT LEAST SOME UPPER AND SOME LOWER PICKS, AND A PLURALITY OF ELASTIC WARP CORE THREADS EACH HAVING A TIGHT INELASTIC SPIRALLY WOUND COVER THEREON. SAID INITIAL FABRIC HAVING AN INITIAL CLOSENESS OF CONSTRUCTION WHICH IS LESS THAN THAT OF THE FABRIC AFTER PROCESSING BY THE PERCENTAGE C, WHERE C IS SUBSTANTIALLY THE NORMAL WASH SHRINKAGE OF THE INITIAL FABRIC, AND, AN INITIAL STRETCH S1 WHICH IS LESS THAN THE FINAL STRETCH SC OF THE FABRIC AFTER PROCESSING WHEREIN S1 IS DETERMINED BY THE FORMULA: S1=SC(1-C/100)-B S1, SC AND C BEING EXPRESSED IN PERCENTAGES, AND MECHANICALLY COMPACTING SAID FABRIC LENGTHWISE BY C PERCNET OF L1 TO A LENGTH OF LC, THE MECHANICAL COMPACTION CHANGING THE ANGLE OF THE SPIRAL COVER OF THE COMPOSITE WARP CORE THREADS TO REDUCE THE GRIP ON THE ELASTIC CORE THREADS THEREOF AND INCREASING THE CLOSENESS OF CONSTRUCTION TO THEREBY PROVIDE INCREASED LONGITUDINAL STRETCH IN THE FABRIC OVER THAT NORMALLY EXPECTED.
