により構成される。According to the present invention, oxalic acid is dissolved in a mixed solution of alcohol and water for a fiber structure containing at least a part of a fibrillated composite filament composed of a polyamide component and a polyester component. It is constituted by a method for treating a fibrous structure composed of fibrillated composite filaments, which is characterized in that a liquid-flow kneading treatment is carried out in a chemical liquid.

It refers to the filaments that are joined together.

が、効果は大きい。The fiber structure of the present invention refers to woven fabric, knitted fabric, non-woven fabric and the like. It is sufficient that at least a part of the fiber structure contains a fibrillated composite filament composed of a polyamide component and a polyester component. However, the fact that a fiber structure having a high density, a swelling, and a span-like texture is obtained depends on peeling and shrinking of the fibrillated composite filament.
The greater the amount of fibrillated composite filaments, the greater the effect.

になるので望ましくない。The alcohol in the present invention is not particularly limited. Specific examples include methanol, ethanol, propanol, butanol, ethylene glycol and butanediol. The propanol may be isopropyl alcohol or 1-propanol. The mixing weight ratio of alcohol and water needs to be 0.10 or more when the weight ratio is expressed by the value of alcohol / water. When it is less than 0.10, the shrinkage rate and shrinkage stress of the polyamide are insufficient, and the effect of peeling and shrinking the fibrillated composite filament cannot be obtained. Further, when it is 0.40 or more, the peeling / shrinking effect is large, and peeling unevenness is less likely to occur, which is preferable. However, if the weight ratio is 2.50 or more, handling becomes very difficult, which is not desirable.

When the concentration is t% or more, the peeling / shrinking effect is large, and peeling unevenness is less likely to occur, which is preferable. However, when a high concentration of oxalic acid is used, the yarn quality of the polyamide is significantly deteriorated, so the content is preferably 40 wt% or less.

When the temperature is at least ° C, the shrinkage / peeling effect is large, which is preferable. However, since polyamide deteriorates at high temperatures, it must be treated at 110 ° C or lower. When it is carried out at a relatively low temperature within the above temperature range, it is necessary to perform a long-time treatment.

It has a slight swelling effect, but has a small effect of peeling and shrinking the fibrillated composite filament. However, by dissolving oxalic acid in a mixed solution of alcohol and water, the polyamide swelling effect is significantly increased, and the fibrillated filament can be peeled and shrunk.

いが得られる。The liquid-flow kneading treatment of the present invention specifically means a liquid-flow kneading treatment by a liquid-jet dyeing machine. In the method of immersing the fiber structure in a chemical solution consisting of alcohol, water and oxalic acid, by adding a liquid-flow rubbing treatment, the composite filaments are easily split, and the fibers after splitting are mixed. Are likely to fall apart. Therefore, even if the concentration of oxalic acid and alcohol is low, it not only has sufficient shrinkage and peeling properties, but it can be processed in a short time, and furthermore, the characteristics of the ultrafine fibers are exhibited in the fiber structure after processing. It is easy to be applied and a better texture is obtained.

The nozzle may be a span nozzle or a filament nozzle, but the filament nozzle is more preferable because of its massaging effect. Further, the soft flow type or the circular type may be used, but the circular type is preferable because the kneading effect is large because the nozzle pressure is easily increased and turbulent flow is easily generated. The bath ratio may be 1: 4 to 1:50, more preferably 1: 8 to 1:15.
