The invention relates to a manufacturing technique of fabrics of polyester-cotton plisse warp knitting western-style clothes, comprising the steps of the preparation of raw materials, warping, complete hair-coiling, the fabric manufacture of grey cloth, unwinding, dyeing and the typing of finished products. The step of the fabric manufacture of the grey cloth adopts four stripping combs for weaving, wherein, the first stripping comb adopts polyester filament in a way of 6 being penetrated and 3 being hollow, and crossband plisses are formed by a manner of combining woven flatness and pad lack; the second stripping comb adopts compact spinning cotton yarn in the way of 1 being penetrated, 6 being hollow, 1 being penetrated and 1 being hollow, and straight strips are formed in a manner of woven flat double stranded weaving; the third stripping comb adopts polyester low stretch yarn in the way of 1 being hollow, 6 being penetrated, 1 being hollow and 1 being penetrated, the blank penetrating part of the second stripping comb is filled up in the manner of woven flat weaving, and straight twin color effect is formed after dyeing; the fourth stripping comb also adopts the polyester low stretch yarn in the manner of symmetrical double needle woven flat weaving, mainly playing the role of solidification so as to cause the fabrics to be more compact. The fabrics have compact texture, novel style, and stereoscopic impression, and are rough while maintaining softness, and the application of the cotton yarn causes the fabrics to have the twin color effect, and enhances the wearing comfort of the fabrics.
