A method of manufacturing leggings having a leg portion and a waistband portion, using a fabric is disclosed. The method includes brushing an outside surface of the fabric once to form a single-brushed surface. The method includes brushing an inside surface of the fabric multiple times to form a multiple-brushed surface. The method includes cutting the fabric into a plurality of pieces for the leg portion and a plurality of pieces for the waistband portion and sewing the pieces together, the waistband portion having a top edge and a bottom edge, the top edge of the waistband portion being narrower than the bottom edge of the waistband portion, the single-brushed surface of the fabric forming an inside legging surface configured to contact a wearer, and the multiple-brushed surface of the fabric forming an outside legging surface. The method includes sewing an elastic band to the top edge of the waistband.

A fabric processing method and component (e.g., a vehicle component) includes providing and/or arranging a first fabric charge and a second fabric charge. A multi-piece fabric assembly is formed for single stage draping by stitching together the first and second fabric charges along a neutral stitching path. The multi-piece fabric assembly is formed into a three-dimensional shape and is then impregnated with a polymeric material to form the component.

Disclosed are cooling materials for clothing and other body gear that may use a discontinuous pattern of highly absorbent polymers coupled to a base fabric that has a low resistance to moisture spread (e.g., a high wicking rate) and lower absorption properties compared to the highly absorbent polymer elements, to manage moisture (e.g., sweat) and body heat. The absorbance of the highly absorbent polymers is greater than that of the base fabric, such as at least two times greater, and the highly absorbent polymer elements may be non-endothermic.

A sewing machine of the present embodiment comprises a movement amount detector which detects a movement amount of fabric, a sewing machine motor serving as a rotary drive source of an upper shaft which applies vertical movement to a needle bar, a shaft angle detector which detects a shaft angle of an output shaft of the upper shaft or the sewing machine motor, and a controller which controls the sewing machine motor based on the detection of the movement amount detector and performs controls of maintaining a constant stitch length. The controller performs controls of maintaining the constant stitch length, by a movement amount of the fabric detected by the movement amount detector in a shaft angle section where a sewing needle is not stuck into a cloth, based on the detection by the shaft angle detector.

An interior part of vehicle capable of improving in design property is manufactured by joining a plurality of pieces of a layered cloth having at least a skin material and a cushion material. The plurality of pieces to be joined are processed with continuous stitches, and the pieces joined with the stitch processing are sewn up, with the front surfaces put together, along ends to be joined. One of the joined plurality of pieces is folded, thus the plurality of pieces are provided, with the front surfaces facing vehicle interior space.
