《天工开物·上篇·乃服》
素罗上不需要织花纹，要想在软纱、绫、绢这些织料上织出波浪、梅花等样式的小花纹，机器上只要比织素罗时多加两片综框和踏板，由一个人边踏边织就行了。
其素罗不起花纹，与软纱绫绢踏成浪梅小花者，视素罗只加桄二扇。
Plain Luo does not need to be woven with patterns. If you want to weave small patterns like waves and plum blossoms on soft gauze, silk, and satin, you only need to add two more heddle frames and treadles to the machine than when weaving plain Luo, and one person can weave while stepping on the treadles.
