Stitch knot

The stitch knots and holes act as stress concentration sites in the laminate microstructure. 

In stitched, knotted and, even more, in knitted reactors dispersion is kept low, because the introduction of eddies at every turn is in practice equivalent to turbulent flow, and there are many turns. Each separated zone thus travels through the reactor as a bolus with almost the same flow velocity in the lumen of the tubing as at the wall, but unfortunately these advantages are obtained... 

The FRP components may be subjected to considerably high temperatures, and it is essential to check the behavior of the threads at such temperatures, as well as in the resin. At the area of the stitch knot, a high amount of sewing thread is involved, so the thermal analysis of these small areas helps to check the actual thermal behavior of the thread inside the FRP laminate. Differential scanning calorimetry (DSC) tests of non-impregnated and impregnated threads in the FRP laminate reflect the heat sustention capacity of particular threads. 

The basic stitch produced in warp knitting is the chain stitch. The yam is looped around the needle stem and another loop of the yam is formed in the hook of the needle and is then pulled through the first loop, itself then becoming the loop held on the needle shaft, whilst another loop is formed in the hook. In this way a chain of interlaced loops is formed. By displacing every other loop onto the next needle, the chains of interlaced loops are linked together to form the simple knotted tricot structure. If one of the yam loops become broken in this type of fabric then the whole fabric, in the line of the yam, will unzip . This problem can be overcome by displacing the throw of the stitches. 

D Knots and knotholes to 63.5 mm width across grain and 12.7 mm larger within specified limits. Limited splits are permitted. Stitching permitted. Limited to Exposure 1 or Interior panels. 

It is also important that the suture material is stable to radiation. This can occur when, following gynecologic cancer, a patient is prescribed abdominal radiation for palliative or curative therapy. The ionizing effect of the radiation may adversely affect suture strength, and may lead to wound dehiscence (Orr et al, 2004). The use of a knotted monofilament suture presents a high risk in such cases, since, if the suture breaks at one point, the entire length of the suture stitch is rendered ineffective in keeping the wound closed. Several small suture stitches may be used but this increases the time of operation and can lead to complications due to the presence of multiple knots. A barbed suture, however, can effectively eliminate both these risks. Since it anchors at multiple points, should the suture break it will still hold the wound tissue in closed apposition at the next barb. Secondly, since the suture stays inside the tissue there is less scar formation.

Individual beads can be stitched by hand in children s garments for 4 years and above, by using core-spun polyester thread. Those must be securely attached with double thread and the end of the thread is to be knotted. A maximum thread end of 1 cm and a minimum of 0.5 cm are acceptable, but floats over 1 cm are not acceptable. 

It is unusual for cords to break centrally, fractures tending to occur at knots or other attachment points, as experiment had shown. Alternatively, the stitch could simply have not been tied correctly in the first place using approved knots and placements in the soft tissues to be joined together. Evidence from the staff involved in the original stitching was contradictory, but it was known that very junior staff had been involved when the patient was stitched. 

III hand-sewn whip stitch or a machine stitch that will show on the outside of the pillow. Use the following invisible stitch to keep the fabric closed and hidden beneath the folds of the fabric Pierce the edge of the fabric on the inside of the pillow, so the knot remains unseen on the inside layer. 

The applied thread tension depends on the thread force being adjusted at the start of the stitching, so that knots are formed at the bottom of the laminate...
