Embodiment 1

[0020] When polyester filaments are placed in a water steamer, the water temperature is 90°C, and the others are the same as above.

Embodiment 2

[0022] Polyester filaments are placed in the natural state for 15 hours to pre-set, and the others are the same as above.

[0023] The present invention first measures the stretchable maximum of rayon, that is, the maximum pressure value that can be applied to it. Since the tensile strength of rayon is weaker than that of polyester filament, the maximum pressure value that can be applied to rayon is used for blending. It can ensure that the tension of rayon and polyester filaments is within its acceptable range, and they are not easy to break; further, before the mixed spinning, the polyester filaments are pretreated, so that the rayon and polyester filaments The characteristics are more consistent, which is conducive to the subsequent process.

Abstract

The invention relates to rayon and polyester filament blended spinning technology. The technology is characterized by including the following steps: 1) placing polyester filaments in a water steaming box for steaming at the water temperature of 85-100 DEG C for 80 minutes; 2) disposing the polyester filaments treated in the step 1) under the natural state for presetting for 10-20 hours; 3) measuring high limit in stretchability of rayon, namely a value of the maximum appliable pressure to the rayon; 4) adopting a water-jet loom for performing blended spinning on the rayon and the polyester filaments with the maximum pressure value. The high limit in stretchability of the rayon, namely the value of the maximum appliable pressure to the rayon, is measured firstly, and stretching resistance capability of the rayon is lower than that of the polyester filaments, so that tension of the rayon and the polyester filaments can be guaranteed within a bearable range by blending with the value of the maximum appliable pressure to the rayon, and both the rayon and the polyester filaments are less prone to breakage.

Description

technical field [0001] The invention relates to a blended textile process of rayon and polyester filament. Background technique [0002] When using different raw material yarns for mixed spinning, the tension of various raw material yarns and suitable processing temperature are important parameters that affect the quality of the final product. Therefore, it is necessary to take into account the characteristics of different raw material yarns when designing the textile process. When rayon and polyester filament are mixed to weave fabrics, due to the large difference in the characteristics of rayon and polyester filament, a specific process is required for weaving. Specifically, rayon has poor water resistance, is easy to break when exposed to water, and has weak tensile strength and is easy to break under force; while polyester filament has high twist and strong tensile strength. In order to take care of the characteristics of different raw materials and ensure the quality o...
