For what on the cut is provided the longitudinal edge - the edge of the fabric
All non-tangled cloth fabrics have a standard weaving structure - on the basis and on the weft. What does this mean? Imagine a long path of material in a roll. Those threads that are laid along its length are called warp threads. And those that go across are duck threads (stress on A). Depending on the direction of the threads, a part of the details is built when sewing garments, taking into account the peculiarities of planting and connection. These are the basic fundamental moments, without which it is simply impossible to sew a quality product.
What does the longitudinal edge indicate - the edge of the fabric?
In fact, the purpose of this edging is of interest to aspiring seamstresses. So, the longitudinal edge (edge) of the fabric indicates to us the direction of the share thread. The edge does not creep, it is fixed by a special textile method and prevents from the decay of threads and fibers along the roll. If there is a piece of cloth in front of you, and you do not know how to determine its share thread, just lay the templates along the edge, strictly parallel to it!
Another, more professional method of determining the share thread is an attempt to stretch the fabric. All non-cloths are slightly stretched against the share and absolutely inelastic in it. That is, if you have a piece of material with a remote edge in front of you, then you need to try to stretch it. It is there where it stretches, there will be a thread of a duck, and where it is static, - an equity thread. Note that the oblique fabric stretches more than anything, but then some deformation will be noticeable.
What is the use of the longitudinal edge (edge) of the tissue? Perhaps few of the readers have ever thought, for what purpose on the monotonous weaving of the fabric, the edge is distinguished by a special kind of weaving and differs markedly from the basic texture. As already mentioned, the edge of the fabric prevents the roll from shedding around the edges. This is the first and leading edge function.
The second, not less important point is the definition of a share. Let's give an example of the imbalance in the equity split.
The beginning seamstress cut the sleeve against the share thread. Everything went according to plan, the pattern was built with precision, the connection performed without violations, tried very hard. But on the fitting, the sleeve turned out to be tight. The hand was impossible to lift, in the forearm, pulled and squeezed, and in the armpit all gathered in wrinkles. The young masteress fell into despair, and was right - it was already impossible to save the sleeve. All because of the fact that the share cloth does not stretch at all, and the student has made the width of the sleeves according to the share and thereby pulled the client's forearms.
Importance when cutting
Of course, the longitudinal edge-edge of the fabric determines the layout of the patterns and the consumption of tissue. Sometimes it seems that the material would have gone much less, decomposed it in a chaotic direction or across the edge. But, as we wrote above, such deviations from the rules are obviously doomed to failure.
Each beginning seamstress knows from the first lessons that the longitudinal edge (the edge of the fabric is the name in the terminology of the sewing disciplines) is a clear and peremptory guide to the direction of the cut and the characteristic by which the material is calculated for the product.
