Description

ные скорости, или пропускают между эластичными лентами, имеющими различную степень эластичности и фрикционности по оттгошению к обрабатываемому волокнистому материалу. При этом вследствие сдавливани обоих тел, между которыми проходит полотно, происходит увеличение поверхности более эластичного тела и соответственно измен етс выт жка материала.These speeds are either passed between elastic ribbons that have different degrees of elasticity and frictional resistance in relation to the fibrous material being processed. In this case, due to the compression of both bodies, between which the web passes, an increase in the surface of the more elastic body occurs and the material stretches accordingly.

Кроме того, парные валики или ленты могут иметь идущие в продольном направлении или под углом около 30° через правильные промежутки ребра или углублени , причем выступы на одном теле вход т в углублени дру гого, что вызывает определенную степень отклонени текстильного полотна от его плоское ти и сообщает материалу выт жку.In addition, paired rollers or ribbons may have ribs or grooves running in a longitudinal direction or at an angle of about 30 ° at regular intervals, with the protrusions on one body entering the recesses of the other, which causes a certain degree of deviation of the textile fabric informs the material of stretching.

При этом раст жение можно производить не сразу, а ступенчато, то есть повторно, череду сь с известными операци ми отделки материала . Причем после последней ступени раст жени в малых област х материал механически деформируют, а затем фиксируют прочным к мойке сшивающим агентом, в качестве которого используют агент, реагир)тощий по меньщей мере с двум гидроксильными rpjTinaMH целлюлозы.In this case, the stretching can be performed not immediately, but stepwise, i.e. repeatedly, alternating with the known material finishing operations. Moreover, after the last stage of stretching in small areas, the material is mechanically deformed and then fixed with a washable crosslinking agent, which is used as an agent that reacts at least with two hydroxyl cellulose rpjTinaMH.

Claims

1. The method of finishing textile materials from natural and chemical fibers by

443974

uniform stretching, about t of l and h and gt1, and so that, in order to increase the tensile strength, the material is moistened, and its stretching is from 30% to., but preferably from 60% to 90 % elongation at break in the direction of stretching, which provides for the displacement of the structural elements of the material, and the stretching is carried out by mechanical means, the points of application of which 10 are infinitely close to one another.

2. A method according to claim 1, characterized in that the material is preferably moistened to 30%, after which it is stretched.

3. A method according to claim 1, characterized in that the material is subjected to stretching in alternate order with the known finishing operations 20.

4. A method according to claim 1, characterized in that the material after the last stage of stretching is mechanically deformed, and then fixed with a smashing agent that is strong for washing.

5. Method pop. 4, characterized in that an agent that reacts with at least two hydroxyl groups is used as a cessation agent.
