How easy to sew and simply? A decatizing of fabric
the Known fact that it is easy for the stretched jeans to return an initial state “ in an oblipochka “ having rinsed several times in contrast water: at first in very hot, then in very cold. After such procedure " jeans; sit down “ on pair of the sizes and again fit a figure tightly.
However very few people know that this process is that other, as “ decatizing “. In standard definition, the decatizing is process of damp and thermal treatment for prevention of the subsequent shrinkage and distortions of details of a cut. Usually such processing is used by
before cutting of a product and in household language means that fabric needs to be washed and stroked in a special way. as a result it gives initial shrinkage which will protect a finished product from reduction in a size, deformation and distortions.
Besides, the decatizing gives two more important advantages: the first - at damp the iron of dekatirovanny fabric it has equal color in seams and on all surface; and the second - from the products sewed from prodekatirovanny fabrics is easier to remove various spots.
A decatizing - process not only industrial, exists several ways for similar processing in house conditions. The choice of this or that way is defined by fabric type: some demand intensive thermal treatment, and some, for example, velveteen and a velvet, and also such synthetic fabrics as kapron and nylon, do not decatize at all.
For a decatizing cotton and linen fabrics the following solution will be required to prepare: warm acetic water from calculation one tablespoon of acetic essence on one liter of water and the prepared kissel from starch and water. The cut of fabric is rinsed at first in acetic water, and then starched for what dissolve starched kissel in cold water. Then fabric is slightly wrung out and hung up on length on a stick. Iron such fabric until it not finally dried, otherwise starch forms the hardly smoothed folds. If suddenly fabric absolutely unexpectedly dried earlier, than you remembered it, it is possible to use a spray. Anyway, it is important to know that it is necessary to iron fabric from seamy side and in the direction of a share thread, that is to move along an edge.
For a decatizing of shtapelny fabrics will need long soaking, it is one night better as process takes 12 - 14 hours. These fabrics give big shrinkage, from here and processing duration. Fabric is immersed in warm water, and then work according to the above described scheme: rinsing in warm acetic water, then in starched solution, drying and a proglazhivaniye.
It is not necessary to be afraid that acetic water can damage fabrics. For example, for color fabrics it can be used for strengthening of color and giving of smoothness not only to an initial cut of fabric, but also usual clothes in the course of use.
Silk fabrics usually give small shrinkage, however other cunning is watched them: if cotton " fabrics; sit down “ strongly, but once, silk it is not strong “ sit down “ but can do it to three a time in a row. The decatizing of such fabrics consists in a proglazhivaniye with moistening: it can be either a damp proutyuzhilnik or the iron about the ferry. Having waited for full cooling of fabric, it should be ironed still few times with full cooling between an ironing.
For a decatizing in house conditions of woolen fabrics warm acetic solution at the rate of 1 dining room will be required to prepare it is false vinegar on two liters of water and to add one teaspoon of salt or sugar which compensates mitigation from vinegar and will give to wool necessary rigidity. In this solution it is necessary to moisten a sheet and to slightly wring out, wrap in it fabric. On the wool wrapped in a sheet it is possible to put from above freight, in this case fabric should be kept under a press of 6 - 8 hours. In case there is no freight, then time should be increased for four hours. After endurance in a wet sheet, wool is carefully ironed from seamy side, drying up fabric the iron.
In cases when definition of composition of fabric causes difficulty, it is possible to carry out the small test on its piece, 10*10 cm in size. For this purpose it is necessary to carry out full procedure of a decatizing as for the fabric giving strong shrinkage then again to measure a sample. If reduction in a size did not happen, so fabric contains synthetic fibers and does not need a decatizing. If you received reduction of the size, then fabric contains cotton or linen fibers. And here if it suddenly stretched, then it, with high probability, the cut of thin wool demanding to itself the gentle address.
There is one more way of definition of composition of fibers of fabric - test on burning. However, at the seeming simplicity the method has quite high error at the expense of the mixed composition of fabrics. At 100% uniform composition of fibers: if the fabric piece when firing lights up and will smell of paper - it is cotton and flax; if turns into fragile pitch and smells of fake feathers - that is wool; if does not burn, and melts, forming a rigid lump - before you synthetics.
Thus, having competently carried out preliminary processing, or a dekatrirovaniye, fabrics taking into account its type, it is possible to start safely cutting and sewing, knowing that in a finished product fabric will behave properly.
