Permanently folded and pinched fabrics and

Process for their manufacture

The invention relates to textile fabrics with improved properties and to an improved method of manufacture permanently pinched and creased fabrics and garments. In particular, the invention relates to treatment textile, cellulose-based materials with polymerizable Materials, in particular thermosetting, polymerizable Synthetic resins and catalysts using an improved process to make durable, chemically treated textile To produce materials that are particularly suitable for the manufacture of garments that have twists and folds granted and made permanent through subsequent follow-up treatment.

then processed into a garment. After completion of the clothes will be the desired gaps and Tricks inserted in the desired shape in this. The garment is then placed in a dedicated oven brought in for curing. The one used for curing in the oven The temperature is sufficient to complete the polymerization reaction of the polymerizable, thermosetting synthetic resins and serves to make the existing synthetic resin insoluble on the spot * and thus the gaps and / or twists in the garment to make it permanent in the desired configuration. Creases and creases imparted to a garment in this way are generally removed by repeated laundering not significantly affected. In general, the above described sequence of treatment steps for the issue of permanent wrinkles and creases on textile fabric postponed or called delayed curing. Attention is drawn to U.S. Patent 2,974,432 which details this process is described.

In practical application depends on the ability of the delayed Curing process to bring about the desired results, by and large of the stability of the polymerizable sub-

Thus it is allowed during the time in which

the fabric is stored, transported and processed into the finished garment, for the synthetic resin there is no way in which it can take place in a conversion. It is essential that during the entire process a premature conversion of the polymerizable material on the tissue before the final stage of the curing process is avoided.

It is known to the person skilled in the art that the temperatures required for the polymerization and curing reaction of polymerizable, thermosetting synthetic resins which are used in the treatment of textiles, be considerably above tree temperature and that such reactions take place at elevated temperatures. Ss kick however, some reactions already occur at moderate temperatures and even at tree temperatures, especially over a long period of time. As the textiles treated with polymerizable, thermosetting synthetic resins and catalysts often are stored for a long period of time, the stability of such fabrics is accordingly seriously impaired, and so is results in significant limitations in the industrial applicability of such methods as described in the US patent 2,974,432.

Days included. From the point of view that emerges from practice, it must be taken into account that the process of making clothes, i.e. cutting, sewing, fitting, etc., takes place in a branch of industry that is different from the Branch of industry that deals with the finishing of textiles is separate and clearly different. In general is It is not even possible on a large technical scale to do the above outlined process steps from impregnation to final curing of the finished garment in quick succession to be carried out one after the other. As a direct consequence of this In connection with the methods used up to now, there arises a problem that must be seriously considered, such as the premature one Implementation of the synthetic resin applied to the fabric during storage, transport or further processing in can be effectively prevented.

Accordingly, the invention has the object of providing an improved method for the production of permanently pinched and to provide pleated cellulosic textile fabrics which obviate the deficiencies and disadvantages of heretofore known methods and compositions.

Another object of the invention is to improve the stability of textile cellulose materials that are thermosetting synthetic resins and catalysts impregnated bind, to improve to the point of final curing and to prevent premature conversion of the polymeric synthetic resin present on the textile material.

Furthermore, it is an object of the invention to provide improved cellulosic textile fabrics which are impregnated with polymerizable, thermosetting synthetic resins and catalysts, and which are resistant to premature polymerisation of the resin during the intermediate processing stages before the final curing step

To solve these problems, a feature of the invention is based on that a selected, inorganic or organic agent is added to the treatment solution which serves to remove moisture to absorb and causes an improvement in the avoidance of premature reactions of the polymerizable material.

Another feature of the present invention is to provide a selected organic or inorganic agent on the chemically impregnated cellulosic textile fabric which effectively reacts the polymerizable, thermosetting synthetic resin to those normally encountered during shipping, storage, and processing of the fabric moderate temperatures prevented.

Another feature of the invention is the manufacture of permanently pinched and folded textile garments or theirs Parts such as sleeves, collars, lapels or trouser legs made of cellulosic textile materials that are coated with a polymerizable, thermosetting resin, a catalyst and a selected one inorganic or organic agents are impregnated, which gives the treated textile material stability and the premature

These selected compounds, which will be described in detail later, are particularly effective in preventing the reaction of the polymerizable, thermosetting synthetic resins at the moderate temperatures normally prevailing in the storage, transport and processing of the treated cellulosic textiles. Due to the improvement achieved by the present invention, it is possible to produce permanently pinched and folded pieces of clothing while avoiding the disadvantages and limitations inherent in the previously known methods »

Another advantage of the invention is based on the fact that the Selected compounds used in conjunction with the resin do not affect the course of the reaction at elevated temperatures ^ 'influence in a more elegant way and therefore the effectiveness of the

it is desirable to report everything that the final Step of curing could seriously inhibit or adversely affect its effectiveness. There is also an advantage of the invention in that the added substances are not recognizable Have an effect on the properties of the fabric after curing and not adversely affect the completion of the product or damaging it.

The inorganic and organic compounds used according to the invention serve to be included in the fabric or in the fibers Absorb water and prevent premature conversion and polymerization of the polymerizable, thermosetting Synthetic resins present on the textile fabric. This result is achieved without affecting the fabric or the finished garment is affected.

According to one aspect of the invention, there is a suitable group Means of neutral or essentially neutral, deliquescent inorganic salts, the halides of calcium, such as Include chlorides, bromides and iodides, cobalt (II) halides, maganium chloride, niokel haloids, nickel nitrate and strontium halides. In general, the colorless, neutral ones become deliquescent Salts preferred. Weakly acidic fluids.

For example close they non-volatile acids, magnesium chloride, zinc chloride, zinc nitrate, aluminum chloride, salts of the Lewis acids, for example Zinc fluoroborate and the like.

When, in conventional processes, cellulosic fabrics are treated with the above-mentioned resins and suitable catalysts and are partially dried without curing, their kink recovery values are essentially unchanged, which is indicative this is due to the fact that only a very slight or even no networking occurs. If then this tissue or the garments made from it are cured immediately after these process steps or a short time afterwards, the kniff recovery is greatly increased, and creases and folds can be incorporated in a permanent way as - * 'after implementation, which goes on during curing.

The consequence of this is that pinch retention the fabric or the garments made from it, which consists of it, which will be given to him at a later date and wrinkles and wrinkles made permanent by hardening to hold, significantly reduced and. the desired pinch retention values are reduced accordingly.

The gradual increase in the kink recovery values for a given fabric, and the corresponding decrease in the kink retention values, which can be determined during the subsequent hardening of the textile material, are clearly evident, even if it is only a matter of hours, if the fabric before the Curing stored at temperatures, d ^ B. above 43 - 52 ⁰ C.
