Cellulose fiber is a substance that is excellent in reproducibility and at the same time is naturally decomposable. In addition, cellulosic fibers have good hygroscopicity, water absorption and texture, and have excellent properties such as ease of processing. However, on the other hand, it has drawbacks such as shrinkage due to washing and hardening of texture due to repeated washing. In addition, fabrics made from cellulosic fibers that have been subjected to wrinkling or pleating have the disadvantage that wrinkles and pleats are gradually lost during repeated washing.

地にホルマリンが残留するという問題がある。[0003] In order to eliminate these drawbacks and to impart morphological stability (shrinkage resistance, durable wrinkling, pleating retention, etc.) to cellulose, various improvements have been conventionally studied. Conventional improvement methods include a resin processing method, a chemical method using a chemical such as formalin, a high-temperature heat treatment method, and a steam treatment method. However, these conventional methods have some problems or are ineffective.
For example, fabrics that have been subjected to resin processing have problems that the strength is reduced and the texture is hard. In the chemical treatment, there is a problem that formalin remains in the dough.

This is where the fibers contain a percentage by weight of water. As a result, it was revealed that an excellent shape stabilizing effect which could not be obtained conventionally can be obtained. The liquid ammonia treatment can be performed, for example, by impregnating the cellulosic fibers with liquid ammonia maintained at a temperature of −33 ° C. or lower under normal pressure. As the impregnation method, a method of dipping in a liquid ammonia bath, a method of spraying or coating liquid ammonia, or the like can be used. Generally, the liquid ammonia impregnation time is suitably from 5 to 40 seconds. After the liquid ammonia treatment, the ammonia adhering to the cellulosic fiber is removed by heating. In the present invention, as the chemical used for the liquid ammonia treatment, in addition to liquid ammonia, methylamine and ethylamine may be used in some cases.

0% by weight or more, preferably 20 to 50% by weight of water is contained. In order to impart this amount of water, the fiber may be immersed in water and then taken out and squeezed with a mangle or the like until a predetermined amount of water is reached, or the measured water may be sprayed on the fiber with a spray. By making the fibers contain the above-mentioned water content in the steam treatment, remarkably excellent morphological stability can be obtained as compared with the case where they are not. Further, by applying a predetermined amount of water in advance, yellowing caused by steam treatment can be prevented. Water content is 20% by weight
Less than that is not preferable because yellowing occurs.

Cellulose-based fibers of 4 kg / cm 2 or more, preferably 4 kg / cm 2 or more
It is performed in high-temperature and high-pressure steam of 10 to 10 kg / cm 2 . The treatment time with the high-temperature and high-pressure steam depends on the pressure of the steam, and cannot be unconditionally determined, but is usually 1 to 60 minutes, preferably 5 to 3 minutes.
0 minutes. If the water vapor pressure is less than 4 kg / cm 2 , the shape stability is insufficient and it is not practical. In performing the high-temperature and high-pressure steam treatment, it is necessary to use a device capable of imparting shrink resistance to the fiber to be treated or of maintaining wrinkles or pleats in a desired state and performing the high-temperature and high-pressure steam treatment. Preferred but not particularly limited. As such an apparatus, for example, a high-pressure container such as a high-pressure cheese dyeing machine, a high-pressure beam dyeing machine, or a high-pressure liquid jet dyeing machine can be used. The drying of the cellulose fibers after the steam treatment is not particularly limited, and is performed in a usual drying step.

度に抑えることができる。[0011] Shrink resistance is usually a problem for textile products. In the case of cellulosic fibrous products, if the shrink-proofing process is not performed sufficiently, the product shrinks due to repeated washing and drying, resulting in a change in form. Although it depends on the conditions such as the woven or knitted structure of the product, the yarn density of the woven or knitted fabric, and the shape of the product, in the case of a cellulose fiber product, the washing shrinkage after washing 10 times generally reaches 3 to 10%. According to the method described above, it is possible to suppress the amount to about 0.5 to 2% without performing resin processing.

This makes it possible to impart excellent washing durability to wrinkles or pleats.

した。The present invention will be described below in more detail with reference to examples. Example 1 A plain woven fabric having a 20th count single yarn warp density of 117 yarns / inch and a 10th count single yarn weft density of 52 yarns / inch was woven using cotton fibers. This was refined and bleached in a conventional manner, and was impregnated with liquid ammonia at −34 ° C. for 10 seconds to be treated. Pants (sewn products) were made using the fabric treated with liquid ammonia, and pleated with a press machine. The pants were sprayed with water at 20% of the weight of the pants, placed in a high-temperature and high-pressure treatment device, and subjected to high-temperature and high-pressure steam treatment at a pressure of 6 kg / cm 2 for 10 minutes. The treated pants were subjected to a washing-drying cycle, and the relationship between the number of washing cycles and the remaining state of the pleats was evaluated. The washing was carried out in accordance with the household washing of No. 103 in the handling picture display described in JIS L0217, and the drying was carried out using a tumble. In the case of applying wrinkles instead of pleats, the relationship between the number of washing cycles and the residual wrinkle state was similarly evaluated. The wrinkle application was performed by packing the above-mentioned cloth treated with liquid ammonia into a tubular body. Further, in order to evaluate the shrink resistance, the cloth was set in a non-tensioned state, subjected to the same high-temperature and high-pressure treatment, and the dimensional change after washing 10 times was measured. The evaluation of residual pleats or wrinkles was performed visually. The results are shown in Table 1.
