Provided is a spiral membrane element that has a restricted outer diameter and is capable of being decreased in operation energy therefor. The element is a spiral membrane element including plural membrane leaves in each of which a permeation-side flow-channel member is interposed between opposed separation membranes a supply-side flow-channel member interposed between any two of the membrane leaves a perforated central pipe on which the membrane leaves and the supply-side flow-channel member are wound and a sealing part that prevents a supply-side flow-channel member from being mixed with a permeation-side flow-channel member. This element has an efficiency index E of 0.005 to 0.10, and the thickness of the supply-side flow-channel member is from 10 to 110 mil.

A knitted component may include a first portion, where the first portion at least partially forms an underfoot area of an article of footwear. A second portion may be included, where the second portion at least partially forms an outer surface of a medial or a lateral side of an article of footwear. A forward portion may extend from an end of the first portion and may include a toebox area in a toe region of the knitted component. A knitted connection structure may be located between the toebox area of the forward portion and the second portion, where the second portion includes a first course, where the toebox area of the second portion includes a second course, and where the first course is secured to the second course through the knitted connection structure.

A knitting method for a warp knitted jacquard three-color figured fabric comprising: (1) defining the basic traverse information of a jacquard bar in non-offset state; (2) A-color pattern area is composed of jacquard pattern texture and jacquard pattern needle supplement texture; (3) B-color pattern area is composed of jacquard pattern texture and jacquard pattern needle supplement texture; (4) a mesh structure of C-color ground net area is composed of jacquard mesh texture and ground bar texture; (5) a pattern contour area is formed by using two jacquard bars to bar the outer contour of the A-color pattern area or the outer contour of the B-color pattern area; (6) the elastic area is composed of a ground bar texture, and a ground bar is used to knit the elastic area texture.

A method for designing a knitted textile or fabric, the method includes receiving graphical input from a user regarding a knit pattern comprised of different types of individual stitches to be included in a textile or fabric design. The method further includes graphically displaying a representation of the textile or fabric design. The method further includes merging sections of continuous stitches of the same type into at least one block. The method further includes graphically displaying the textile or fabric design as a pattern of the at least one block. The method further includes applying edge rolling indicators and/or folding indicators to the displayed pattern of the at least one block, where the edge rolling and/or folding indicators respectively and graphically illustrate predicted edge rolling and folding behaviors of a physical textile or fabric.

A woven textile for shoe upper includes a main body. The main body includes a woven portion and at least one braiding portion. The main body defines a horizontal direction and a longitudinal direction. The woven portion includes a plurality of longitudinal threads aligned along the horizontal direction. Each of the longitudinal threads extends along the longitudinal direction. Two ends of the woven portion along the longitudinal direction are a first end and a second end. At least one of the longitudinal threads extends and is knotted itself from the first end or the second end of the woven portion away from the woven portion to form the at least one braiding portion.

An auxetic polygonal cell may have a plurality of chiral structures capable of rotation. The plurality of chiral structures may at least partially enclose a volume. Each of the chiral structures may include a first cross member having a first set of distal ends and a second cross member intersecting the first cross member, the second cross member having a second set of distal ends. The chiral structures may also include a first set of legs, wherein each leg of the first set of legs extends from at least one distal end of the first set of distal ends and a second set of legs, wherein each leg of the second set of legs extends from at least one distal end of the second set of distal ends.
