Embodiment 1
[0028] The warp yarn is made of ramie fiber and bamboo fiber blended yarn with a mixing ratio of 40:60, that is, the ramie fiber accounts for 40% of the warp yarn proportion in the warp yarn, and the bamboo fiber accounts for 60% of the warp yarn proportion; the weft yarn adopts cotton R10 S ; Warp and weft density: 300×220 threads / 10cm; Width: 152 cm. Warp shrinkage≦-2.0% Weft shrinkage≦-5.0%.
[0029] The weaving method of ramie fiber and bamboo fiber denim in this embodiment, the weaving process is formed by interweaving warp yarns and weft yarns, the warp yarns go through the processes of winding, warping, sizing, drafting, weaving, and gray fabric inspection, and the weft yarns go through bobbins After the yarn is twisted, it enters the weaving process with the warp yarn; the main production process points are:
[0030] In the winding process, the loose winding machine generally adopts a linear speed of 800-850m / min. The pressure of the loose package arm is selected at ...
Embodiment 2
[0038] In the sizing process, ethylenediamine is used as a modifier, the concentration of ethylenediamine is 15g / l, the concentration of potassium hydroxide is 18g / L, the temperature is 60°C, and the time is 70min. The other procedures of the weaving method are the same as in Example 1. The ramie fiber and bamboo fiber blended yarn with a mixing ratio of 50:50 is used, that is, the ramie fiber accounts for 50% of the warp yarn proportion in the warp yarn, and the bamboo fiber accounts for 50% of the warp yarn proportion. Weft density: 300×220 pieces / 10cm; width : 152 cm. Warp shrinkage≦-2.0% Weft shrinkage≦-5.0%.
Embodiment 3
[0040] In the sizing process, ethylenediamine is used as a modifier, the concentration of ethylenediamine is 30g / l, the concentration of sodium hydroxide is 15g / L, the temperature is 50°C, and the time is 90min. The weaving method is the same as in Example 1, and the warp yarn is Ramie fiber and bamboo fiber blended yarn with a mixing ratio of 60:40, that is, in the warp yarn, ramie fiber accounts for 60% of the warp yarn proportion, bamboo fiber accounts for 40% of the warp yarn proportion, and the weft yarn uses cotton RSB12 S / 20D; Weft density: 300×220 threads / 10cm; Width: 152cm. Warp shrinkage≦-2.0% Weft shrinkage≦-5.0%.
