Crepe fabric is schrunk by the wet treatment, such as washing and laundry. This property is a great fault of this fabric and owing to this, its use has been restricted. After scouring, crepe fabric makes a finish by the tenter to obtain the desired width of fabric and good appearance of the crepe effect. The above fault is due to the swelling property of fibre, the strong twist of yarn and, especially, to the influence stretching at the tentering finish. So, we expected to obtain a method of improvement by decreasing Crepe fabric is schrunk by the wet treatment, such as washing and laundry. This property is a great fault of this fabric and owing to this, its use has been restricted. After scouring, crepe fabric makes a finish by the tenter to obtain the desired width of fabric and good appearance of the crepe effect. The above fault is due to the swelling property of fibre, the strong twist of yarn and, especially, to the influence stretching at the tentering finish. So, we expected to obtain a method of improvement by decreasing the swelling property of fibre while stretching at the tentering finish and by settling the crepe effect. And, in this experiment, by the treatments of formaldehyde and urea-formaldehyde resine, we tried to find some finishing method to make silk crepe and silk-rayon union crepe unshrinkable. Thus we obtained the following result as we expected;(1) The formaldehyde treatment is suitable for silk crepe but not applicable to rayon crepe and rayon-silk union crepe for the reason that it decreases the tensile strength of rayon and its affinity for dyestuff. By this treatment, the initial shrinkage of silk crepe, i. e., 10% for warp, 7% for weft, was reduced to 2%. (2) The urea-formaldehyde resine finish is suitable for rayon crepe and rayon-silk union crepe. By this treatment, the initial shrinkage of rayon-silk union crepe, i.e., 36% for weft, 23% for warp, was reduced to 10%.
