The resultant fibers with the protein surface layer divided in particles by cracks affords bulky textile products with an improved texture.

Abstract: Pattern data for at least two sizes are converted to knit data, regarding knitted products to be graded. Regarding the knit data for at least two sizes, characteristic points specifying shapes of the knitted products and intermediate shapes specifying shapes of the knitted products between the characteristic points are generated. By interpolating or extrapolating the characteristic points and the intermediate shapes, according to a desired size of the knitted products, characteristic points and intermediate shapes for the desired size are generated. Closed loops are generated by connecting the characteristic points and the intermediate shapes, and knit data for the desired size is generated by allocating knitted stitches within patterns specified by the closed loops. Without pattern data for intermediate sizes, knit data for the intermediate sizes are generated from the two size knit data.

Remaining stitches at the first fabric upper end are held on one needle bed, and remaining stitches at the second fabric upper end are held on the other needle bed. Fabrics that follow the remaining stitches at the first fabric upper end and the remaining stitches at the second fabric upper end are knitted toward the heel of the footwear.

Abstract: The virtual shape of knit product comprising plural parts and mutually divided in the knit data is simulated. The connection information regarding how said parts are mutually connected is obtained based upon the knit data or the pattern data of the knit product, and the plural parts are mutually based upon the obtained connection information. The virtual shape of the knit product is deformed by deforming the plural parts according to the forces acting on the plural parts. At least one of the plural parts is stretched automatically or according to at least an instruction by a user, and then, the virtual shape of the knit product is re-deformed to a natural shape by re-deforming the plural parts according to the forces acting on the plural parts. Then, stitches are allocated within the plural parts, and the allocation of the stitches is smoothed within the plural parts.

Abstract: Initial pattern data (50) and gauge data are stored, the pattern data is converted into knitting data based on the gauge data, and a knitted product is test-knitted. Sizes of the test-knitted product are compared with sizes indicated by the initial pattern data (50), and the pattern data or the knitting data is corrected. The correction amounts for the pattern data or for knitting data for two sizes are stored, and interpolation or extrapolation is performed based on the stored correction amounts to correct pattern data or knitting data for other sizes.

Abstract: A method for knitting a shoe upper capable of forming a new stretch preventing section different from a conventional stretch preventing section, and a shoe upper obtained through such knitting method are provided. The shoe upper including a base knitted fabric portion (1F) that covers a foot of a wearer is knitted. In the knitting, a stretch preventing section (20) configured by a knitted fabric of a plain structure is knitted, where one end in a wale direction is connected to the base knitted fabric portion (1F) and another end in the wale direction is not connected to the base knitted fabric portion (1F). The stretch preventing section (20) in which one end is fixed and the other end is not fixed is curled to a tubular shape. The curled stretch preventing section (20) is thicker than the other portions, thus suppressing the stretch of the shoe upper.
