ERD vertical-striped trousersMultiple complex processes are combined, the fabric is aligned, and three-dimensional shaping is achieved. The final garment is carefully controlled through multiple layers of quality checks. The overall production process has a much higher threshold than the conventional plain-colored casual pants available on the market. The fabric is made of a vertical color-spliced twill weave of navy blue and olive green. The width and spacing of the stripes are precisely calibrated. The twill fabric is stiff and well-shaped, with good draping and stability. However, the cutting loss is extremely high. The biggest challenge in the finished product is achieving precise alignment of the vertical stripes throughout the entire area. The front piece has double pleated sections, side seams, back piece, waistband, and trouser leg. All the joint positions must have vertical and continuous stripes without any breaks. During the cutting process, the fabric's warp tension is locked throughout the layout stage to prevent any tearing or stretching that could cause the stripes to be skewed. The fabric loss is 30% higher than that of ordinary plain-colored pants. The silhouette is a classic carrot-shaped figure. The core shaping process is the double-layer symmetrical pleating on the front piece. Two sets of live pleats are fixed at specific points and sewn. The depth of the pleats, the width of the pleat closure, and the execution of the unified standards are all standardized. During sewing, the fabric is layered and sent through the cutting machine to control the fabric's slip, ensuring natural and undistorted draping. There is no twisting or folding. The waistband uses the same stripe fabric for full-seam stitching. The waistband flap is fixed at equal intervals with the waistband. Each joint seam requires seamless connection of the vertical stripes. Any slight misalignment of the stripes will be identified as defective. The side seams and crotch of the finished garment are reinforced with a high-density double-line sandwiching process. The twill fabric is sewn with a lowered feeding pressure to avoid sewing tension that could damage the stripe regularity. After all the sewing processes are completed, it enters the three-dimensional steam setting process. The vertical stripes are aligned vertically and the vertical degree of the trouser body is corrected through segmented ironing and adjustment. The pre-shrinkage ratio of the fabric is locked to avoid distortion and collapse of the stripes after washing. From the control of the woven fabric, high-precision stripe cutting, three-dimensional pleating sewing to the final garment shaping, dozens of processes are closely linked. Any deviation in any step will directly damage the overall texture of the finished garment. The quality control and selection standards for this product are extremely strict.
