Abstract: A knitting machine and a method to be accomplished on said machine are described, which are suitable for the production of knitwear from hard, inelastic thread material, e.g. from metal threads. According to the invention, at knitting systems (8a, 8b) provided for this purpose, knitting needles (2) are raised to pick up threads, which are then preformed over the upper edges of knocking-over/holding-down sinkers (3) to form loops. Thereafter the stitch formation takes place by needle and sinker movements directed in opposite directions in the manner of the relative technique.
Abstract: An intarsia pattern knitting fabric which is not likely to cause thread jamming, eliminates the need of divided knitting, and provides a good productivity even when a cylindrical knitting fabric is to be knit. A two-piece-bed flat knitting machine, wherein a carriage and an intarsia carrier capable of knitting by two sets of cams are used to knit two courses of knitting fabric by moving a carriage six courses. An intarsia pattern is knit at a front needle bed (FB), and a knitting yarn between the intarsia carrier at rest near an interface portion and a knitting needle (F) is used to kick back the intarsia carrier by means of the third-course moving of the carriage, and a rear body is knit while the yarn is hooked on an unused knitting needle (F) in a rear needle bed (BB). The sixth-course moving of the carriage releases a knitting yarn from the knitting needle (F) in the rear needle bed (BB) while the rear body is being knit.
Abstract: A fabrics for producing jeans, in particular, a knitted fabric for producing indigo-dyed cotton denim jeans, which is suitable for producing four-season type jeans, is provided. Here, raw yarn obtained by dyeing 100% cotton yarn with natural indigo dyestuffs is knitted by a ring-type knitting machine, to thus provide a knitted fabric for producing four-season type indigo-dyed cotton denim jeans which possesses color tones such as blue and black peculiar to jeans as well as possesses functions such as flexibility, ventilation, warmth-keeping performance, and elasticity, and which can be also put on in midsummer and midwinter. Cotton denim jeans are not knitted by a cotton knitting machine which discriminates warp and weft to thus cause skin friction and creases, but are knitted with the knitted fabric by a ring-type knitting machine without discrimination of warp and weft.
Abstract: The invention concerns a method and a circular machine for manufacturing socks with closed toes with the use of picking-up means placed on several linked sectors, which are movable between an annular position corresponding to the cylinder with needles of the machine and a linear position on two parallel touching lines. The sock is picked-up from the cylinder by the pick-up means in the first position and transferred away from the machine, and while the machine can be restarted, the sock is turned upside down, the linked sectors supporting the pick-up means closed to form to parallel rows and the ends of the sock joined so as to close the toe.
Abstract: A knitted fabric having moisture management properties. The fabric is formed from filamentary yarns and spun yarns, both the filamentary and spun yarns having substantially the same weight per unit of length. The fabric is knitted with so that the courses alternate between a filamentary yarn and a spun yarn.
Abstract: Circular-knit, elastic, single-knit jersey fabric, of spun and/or continuous filament hard yarns with bare spandex plated in every course, has a cover factor in the range of 1.3 to 1.9, a basis weight from 140 to 240 g/m2, an elongation of 60% or more and low shrinkage. The circular knit, single-knit jersey fabric is produced by maintaining the draft of the spandex at or below 2× (100% elongation) and maintaining the finishing and drying temperature(s) below the spandex heat set temperature. The knit fabric meets the end-use specifications without heat setting.

The yarn is transmitted from yarn feeders to cylinders and then knitted to clothes and wound by the fabric winding system. The apparatus is characterized in that upper and lower cylinder mechanisms are all interchangeable so that the upper cylinder can be replaced with radial dust cleaning system. In addition, an upper support rack and a set of rings for feeding thread can be mounted on the base. Therefore, the present invention has multi-functions, wherein the upper and lower cylinders can be adjusted or replaced, or added with optional elements such as an upper support rack, rings for feeding thread and radial dust cleaning system in order to convert the model of producing fabric and offer a wide range of applications.
