3.6 Construction. The coat shall be constructed as specified in Table III; however, the manufacturer is not required to follow the exact sequence of operations as listed therein. The stitches per inch specified in Table III shall be interpreted to be the minimum and the maximum stitches per inch.

Additional basting and holding stitching to facilitate the manufacture of the coat will be permitted, provided the thread used for the additional basting and holding stitching is removed or shall not show on the finished coat.

3.6.1 Stitches and seams. Seaming shall be consistent and exhibit a uniform appearance and shall conform to the ASTM D6193. Where two (2) or more seam or stitch types are specified for the same part of an operation, any one of them may be used. Seam allowances shall be maintained with seams sewn so that no raw edges, run-offs, twists, pleats, puckers, or open seams will result. All seams shall start and finish evenly. Thread tension shall be maintained so that there will be no tight or loose stitching.

Edge stitching and topstitching shall be uniformly gauged throughout the coat. The depth between the fold of seams that are required to be worked out shall be less than 1/16 inch. The guides and the knives for the overedge machines shall be set to trim only the raveled edges of the fabric.

3.6.1.1 Type 301 and 306 stitching. Ends of all stitching shall be backstitched or overstitched not less than 1/4 inch except where ends are turned under or caught in other seams or stitching. Ends of a continuous line of stitching shall be overlapped not less than 1/2 inch except on labels where a minimum of three stitch overlap is required. Thread tension shall be maintained so that there will be no loose stitching resulting in loose bobbin or needle thread or excessively tight stitching resulting in puckering of the materials sewn. The lock stitch shall be imbedded in the materials sewn.

3.6.1.1.1 Repairs of Type 301 and 306 stitching. Repairs shall be as follows:

a. When thread breaks or bobbin run-outs occur during stitching, the stitching shall be repaired by restarting the stitching a minimum of 1/2 inch in back of the end of the stitching. 1/

b. Thread breaks or two or more consecutive skipped or run-off stitches noted during end item inspection shall be repaired by overstitching. The stitching shall start a minimum of 1/2 inch in back of the defective area; continue over the defective area; and extend a minimum of 1/2 inch beyond the defective area onto the existing stitching. Loose or excessively tight stitching shall be repaired by removing the defective stitching without damaging the materials and restitching in the required manner. 1/

1/ When making the above repairs, the ends of the stitching are not required to be backstitched.

The loose ends shall be trimmed.

CAUTION: Pulling or breaking the loose ends is not allowed.

3.6.1.2 Type 401, 502, 503, and 504 stitching. Thread tension shall be maintained so that there will be no loose stitching. Where 401 stitch type is used the looper (underthread) shall be on the inside of the finished coat. All repairs shall be in accordance with 3.6.1.1.1 a and b, except substitute 3/4 inch for 1/2 inch wherever 1/2 inch appears. Repairs to stitch type 401 may be accomplished by use of stitch type 301.

3.6.1.3 Type 101 and 103 stitching. Tension of 101 stitch tacking shall be adjusted and maintained so there will be no loose stitching resulting in loose underneath or top threads, excessively tight stitching, or a puckered outward appearance of the coat. The underneath loop shall be on the inside of the coat, unless otherwise specified in the table of operations (see Table III).

3.6.1.3.1 Repairs of Type 101 and 103 stitching. Repairs shall be accomplished by superimposing new tack or blind stitching in same location after removing threads of first broken tack or blind stitching. When repairing blind stitching, superimpose stitching 1/2 inch over loose ends of broken stitching.

3.6.2 Bartacks. Bartacks shall measure 3/16 inch long, and be free from thread breaks and loose stitching.

3.6.3 Appearance of seams. Puckered seams shall be examined at a distance of three (3) feet in comparison with AATCC 88B. Puckering on a major portion of a seam that is worse than a rating of

4.0 shall be scored as a puckered seam. The test method for the appearance of seams shall be as specified in Table VI.

3.6.4 Buttonholes. The buttonholes shall be the eyelet end, square bar, cut first type, reinforced with gimp.

The purl of the buttonhole shall be on the outside of the coat. The ends of the gimp shall be pulled through to the underside. The ends of the buttonhole stitching shall be tacked by machine, the width of the bar section, catching the ends of the buttonhole stitching in the gimp. The finished size of the buttonhole cut is specified in Table III.
