Stitches per inch

We strengthen our garments at the most basic level the seams. Our stitch-per-inch count is higher than industry trends. 

An example of a garment assembly page of a tech-pack is shown in Figure 2.7. This page includes the sequence of assembly operations along with the stitch count (stitches per inch), seam and stitch notations, machine type for each operation, and any special instmctions assisting the apparel production. The component sketch area shows the components that are available for assembly. 

The stitch properties are stitch size and stitch consistency. Stitch size includes stitch length (SPI — stitches per inch, Figure 10.3), stitch width (distance between the outermost lines of stitches) and depth (distance between the upper and lower parts of the... 

The ASTM D 6193 standard also includes sewing applications for buttons/snaps/ hook and eye attachments, buttonhole stitching, bartack stitching, tacking, specialty stitching and seams and guide to count stitches per inch. 

Most safety officers are familiar with the many fibers used in cut-resistant personal protection equipment (PPE). But cut protection involves more than the base material of the glove. Factors such as the type of construction (types of weave and stitches per square inch), the thickness and type of coating and the basic weight of the fabric rather than the overall glove weight all factor into the glove s performance. 

The weight of a knit is determined by the dimension of the yam and the gauge of the machine. The density of the knit is defined by the number of courses and wales that can be counted per unit length. This fabric characteristic is generally expressed by the number of courses per unit of length of the knit fabric or by the number of wales across the width of the knit. These values are expressed in units per centimetre or by inch, depending on the chosen unit of measure. The total density of stitches of the knit is thus defined by the number of loops or stitches per unit of surface area, or the number of courses mulliphed by the number of wales.
