止せしめるごとき湿潤処理方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for the wet treatment, in particular for dyeing or bleaching, of woven materials or mesh materials comprising fibers capable of being cold dyed. The present invention relates to a wet processing method, such as removing water from the material after applying it, applying a treatment solution to the material in an application step, and resting the material in the form of a roll.

間状態で休止させた。 Conventionally, the dyeing of textile materials using the cold rest method was carried out as follows: after a wet treatment (such as bleaching or washing) the material was first removed of water and then dried. The dried material was then dyed in a foulard dyeing machine, rolled into rolls and then allowed to rest in the cold.

の溶液が混合して染料溶液が徐々に稀釈される危
険があるからである。 Conventionally, this known method involves significant plant expense and energy consumption, as it requires intermediate drying between the water removal and application steps. On the other hand, with this known method it is not possible to omit intermediate drying and to operate "wet-in-wet" in the application process. Because if wet material is introduced into the foulard dye application process, these
This is because there is a risk that the dye solution will be gradually diluted due to mixing of the two solutions.

る。 A further disadvantage of this known method is the risk of overdrying the material between the water removal step and the application step. If fibers, especially cotton, are dried hot, and especially if the moisture content fluctuates, overdrying of the material can easily occur, resulting in local wetting and uneven production of the material in the next application step. becomes.

を改善したものを製造するにある。 It is therefore an object of the present invention to produce a method as described above, which eliminates the need for intermediate drying between the water removal step and the application step, and which, in addition, improves the uniformity of material treatment during the application step. .

することによつて達成された。 The purpose of this is to feed the material with the moisture reached during water removal to the application step; to carry out an additional application of the solution to the damp material in the application step; to select the amount of solution to be added in the application step by the roll. This was achieved by selecting a solution that still held the solution under the winding tension.

る適用溶液の中へ入り得ないからである。 In the tests on which the present invention is based, surprisingly, the prejudice against "wet-medium-wet dyeing" that existed among experts in the art in the past
It has been found that if the dyeing (or any other application) is not carried out in the conventional manner by means of a Foulard dyeing machine, but is carried out purely in the form of additional applications of solution, no discoveries will be made. Such additional application of the solution can be carried out, in particular, by pouring, spraying or adding it in the form of a foam onto the material. The material is sent to the application step retaining the moisture achieved during water removal without intermediate drying. The purely additive application of the solution in the application step eliminates the risk of mixing or diluting the solution. This is because moisture in the material cannot enter into the application solution outside the material.

の染色の優れた一様性となる。 Surprisingly, this "wet-wet" application results in a considerable improvement in the quality of the application. The moisture still contained in the material after water removal ensures that the entire material is uniformly wetted with the application solution. As a result, the material absorbs, for example, applied application solutions completely uniformly, resulting in, for example, in the case of dyeing, an excellent uniformity of the dyeing of the material.
