Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
167 words
THE METHOD OF MAKING A SEWING THREAD WHICH WILL NOT STRETCH OR ELONGATE UNDER TENSION WHEN DRY BUT WHICH WILL STRETCH AND ELONGATE UNDER TENSION UPON IMMERSION IN WATER, THEREBY TO ELIMINATE SEAM PUCKER WHEN A SEAM IS SEWN WITH THE THREAD, WHICH METHOD INCLUDES INCREASING THE STRETCHABILITY OF A CELLULOSE THREAD BY CONTRACTING THE SAME IN A LENGTHWISE DIRECTION WHILE FREE OF TENSION, AN AMOUNT SUFFICIENT TO PRODUCE UNDER SEAM TENSION THE DEGREE OF ELONGATION THAT WILL PREVENT SEAM PUCKER WHEN PLACED IN WATER, SAID CONTRACTION BEING EFFECTED BY APPLYING TO SAID THREAD CAUSTIC SODA OF MERCERIZING STRENGTH, THERINAFTER REMOVING THE CAUSTIC SODA FROM THE CONTRACTED THREAD BY RINSING THE SAME WITH WATER WHILE STILL FREE OF TENSION, DRYING THE RINSED THREAD WHILE STILL FREE OF TENSION, COATING THE DRIED CONTRACTED THREAD WITH A WATER SOLUBLE AND SUBSTANTIALLY NON-ELASTIC ADHESIVE WHICH WILL DRY TO A TACK-FREE CONDITION WHILE STILL FREE OF TENSION, AND DRYING THE ADHESIVE AND THREAD WHILE THE LATTER STILL IS FREE OF TENSION.
