Complete garment knitting is a next-generation form of fully fashioned knitting that adds the capability of making a 3-dimensional full garment. Unlike other fully fashioned knitting, where the shaped pieces must still be sewn together, finished complete knitted garments do not have seams. The knitting machines' computerized instructions direct movement of hundreds of needles to construct and connect several tubular knitted forms to create a complete garment in a single production step.
The complete garment system's advantages lie in 1) a further reduction in materials beyond even fully fashioned production by eliminating seam allowances and 2) faster time to market by eliminating the need for sewing any components. These factors increases cost-effectiveness (especially important when using high-performance materials such as aramids for composites). One might also argue that cutting down on wasted by-product selvage makes complete garment better for the environment.
Two companies manufacture complete garment knitting machines: Shima Seiki and Stoll.
Examples of structures that are most often made with the complete garment technique are clothing (sportswear to sweaters) or technical textiles (car seat covers which also incorporate additional structural elements such as metal and plastic fasteners, composite preforms). The machines can produce a variety of topologies that were more difficult or impossible to create with knitting machines before, including: connected tubes, circles, open cuboids, and even spheres (for helmet shells and other preforms).
Complete garment knitting requires two needle beds for three-dimensional structures (such as clothing). As is the case with all fully fashioned knitting, machines require individual single needle selection (through electronic control) and presser feet (to hold down formed loops).
Note: Aspects of complete garment knitting such as changing the fabric width or diameter and connecting two sides of the structure together are also possible with a single needle bed for two-dimensional or 'flat' structures—and are achieved by:
Changing knit structure (e.g. rib to interlock)
Varying the structural elements (stitch length, weft insertion, knit, tuck, float)
Shaping through loop transfer
Wale fashioning by 'needle parking'
Segmented takedown for varying rates of takedown across the width of the fabric
Crochet is a process of creating textiles by using a crochet hook to interlock loops of yarn, thread, or strands of other materials. The name is derived from the French term crochet, meaning 'hook'. Hooks can be made from a variety of materials, such as metal, wood, bamboo, or plastic. The key difference between crochet and knitting, beyond the implements used for their production, is that each stitch in crochet is completed before the next one is begun, while knitting keeps many stitches open at a time. Some variant forms of crochet, such as Tunisian crochet and broomstick lace, do keep multiple crochet stitches open at a time.
Knitting is a method for production of textile fabrics by interlacing yarn loops with loops of the same or other yarns. It is used to create many types of garments. Knitting may be done by hand or by machine.
A knitting needle or knitting pin is a tool in hand-knitting to produce knitted fabrics. They generally have a long shaft and taper at their end, but they are not nearly as sharp as sewing needles. Their purpose is two-fold. The long shaft holds the active (unsecured) stitches of the fabric, to prevent them from unravelling, whereas the tapered ends are used to form new stitches. Most commonly, a new stitch is formed by inserting the tapered end through an active stitch, catching a loop of fresh yarn and drawing it through the stitch; this secures the initial stitch and forms a new active stitch in its place. In specialized forms of knitting the needle may be passed between active stitches being held on another needle, or indeed between/through inactive stitches that have been knit previously.
An overlock is a kind of stitch that sews over the edge of one or two pieces of cloth for edging, hemming, or seaming. Usually an overlock sewing machine will cut the edges of the cloth as they are fed through, though some are made without cutters. The inclusion of automated cutters allows overlock machines to create finished seams easily and quickly. An overlock sewing machine differs from a lockstitch sewing machine in that it uses loopers fed by multiple thread cones rather than a bobbin. Loopers serve to create thread loops that pass from the needle thread to the edges of the fabric so that the edges of the fabric are contained within the seam.
Fibre-reinforced plastic is a composite material made of a polymer matrix reinforced with fibres. The fibres are usually glass, carbon, aramid, or basalt. Rarely, other fibres such as paper, wood, boron, or asbestos have been used. The polymer is usually an epoxy, vinyl ester, or polyester thermosetting plastic, though phenol formaldehyde resins are still in use.
Knitting is the process of using two or more needles to pull and loop yarn into a series of interconnected loops in order to create a finished garment or some other type of fabric. The word is derived from knot, thought to originate from the Dutch verb knutten, which is similar to the Old English cnyttan, "to knot". Its origins lie in the basic human need for clothing for protection against the elements. More recently, hand knitting has become less a necessary skill and more of a hobby.
Nålebinding is a fabric creation technique predating both knitting and crochet. Also known in English as "knotless netting", "knotless knitting", or "single-needle knitting", the technique is distinct from crochet in that it involves passing the full length of the working thread through each loop, unlike crochet where the work is formed only of loops, never involving the free end. It also differs from knitting in that lengths must be pieced together during the process of nålebinding, rather than a continuous strand of yarn that can easily be pulled out. Archaeological specimens of fabric made by nålebinding can be difficult to distinguish from knitted fabric.
The term "gauge" is used in knitting to describe the fineness size of knitting machines. It is used in both hand knitting and machine knitting. The phrase in both instances refers to the number of stitches per inch rather than the size of the finished article of clothing. The gauge is calculated by counting the stitches or needles across a number of inches, then dividing by the sample's width in inches.
A knitting machine is a device used to create knitted fabrics in a semi or fully automated fashion. There are numerous types of knitting machines, ranging from simple spool or board templates with no moving parts to highly complex mechanisms controlled by electronics. All, however, produce various types of knitted fabrics, usually either flat or tubular, and of varying degrees of complexity. Pattern stitches can be selected by hand manipulation of the needles, push-buttons and dials, mechanical punch cards, or electronic pattern reading devices and computers.
Sweater design is a specialization of fashion design in which knitted sweaters are designed to fulfill certain aesthetic, functional and commercial criteria. The designer typically considers factors such as the insulating power of the sweater ; the fashion of its colors, patterns, silhouette and style lines, particularly the neckline and waistline; the convenience and practicality of its cut; and in commercial design, the cost of its production and the profitability of its price point. Sweater designs are often published in books and knitting magazines. Sweater design is an old art, but continues to attract new designers such as Nicky Epstein and Meg Swansen.
Warp knitting is defined as a loop-forming process in which the yarn is fed into the knitting zone, parallel to the fabric selvage. It forms vertical loops in one course and then moves diagonally to knit the next course. Thus the yarns zigzag from side to side along the length of the fabric. Each stitch in a course is made by many different yarns. Each stitch in one wale is made by several different yarns.
Flat knitting is a method for producing knitted fabrics in which the work is turned periodically; that is, the fabric is worked with alternating sides facing the knitter. Another method of achieving the same result is to knit alternately from right to left and left to right without turning; this back-and-forth technique requires either innate or learned ambidextrous motor skills. The two sides of the fabric are usually designated as the right side and the wrong side.
Knitted fabric is a textile that results from knitting, the process of inter-looping of yarns or inter-meshing of loops. Its properties are distinct from woven fabric in that it is more flexible and can be more readily constructed into smaller pieces, making it ideal for socks and hats.
The manufacture of textiles is one of the oldest of human technologies. To make textiles, the first requirement is a source of fiber from which a yarn can be made, primarily by spinning. The yarn is processed by knitting or weaving, which turns yarn into cloth. The machine used for weaving is the loom. For decoration, the process of colouring yarn or the finished material is dyeing. For more information of the various steps, see textile manufacturing.
Fully fashioned stockings (FFS), are stockings with characteristic reinforcements on the heel and top, a so-called keyhole at the back of the top, and a stitched back seam in between. They are made to be worn with a garter belt and are today considered a vintage design of hosiery after largely having been replaced by seamless stockings and pantyhose from the 1960s onwards. Fully fashioned stockings are usually made from nylon and thus have very little stretch compared with modern stockings and pantyhose.
Jersey is a knit fabric used predominantly for clothing manufacture. It was originally made of wool, but is now made of wool, cotton and synthetic fibers.
In the textile arts, a stitch is a single turn or loop of thread, or yarn. Stitches are the fundamental elements of sewing, knitting, embroidery, crochet, and needle lace-making, whether by hand or machine. A variety of stitches, each with one or more names, are used for specific purposes.
Sewing is the craft of fastening or attaching objects using stitches made with needle and thread. Sewing is one of the oldest of the textile arts, arising in the Paleolithic Era. Although usually associated with clothing and household linens, sewing is used in a variety of crafts and industries, including shoemaking, upholstery, sailmaking, bookbinding and the manufacturing of some kinds of sporting goods. Sewing is the fundamental process underlying a variety of textile arts and crafts, including embroidery, tapestry, quilting, appliqué and patchwork.
Dimensional stability is the change of dimensions in textile products when they are washed or relaxed. The change is always expressed relative to the dimensions before the exposure of washing or relaxing. Shrinkage is also called residual shrinkage and measured in percentage. The major cause of shrinkages is the release of stresses and strains introduced in manufacturing processes. Textile manufacturing is based on the conversion of fiber into yarn, yarn into fabric, includes spinning, weaving, or knitting, etc. The fabric passes through many inevitable changes and mechanical forces during this journey. When the products are immersed in water, the water acts as a relaxing medium, and all stresses and strains are relaxed and the fabric tries to come back to its original state. The dimensional stability of textile materials is an important quality parameter. Failing and unstable materials can cause deforming of the garments or products. Shrinkage is tested at various stages, but most importantly before cutting the fabric into further sewn products and after cutting and sewing prior to supplying the products to buyers and consumers. It is a required parameter of quality control to ensure the sizes of the products to avoid any complaints regarding deformation or change in dimensions after domestic laundry. The tests are conducted with provided specifications of buyers imitating the same conditions like washing cycle time, temperature and water ratio and fabric load and sometimes top loading and front loading washing machines are chosen to authenticate the test and assurance of the results. This procedure provides standard and alternate home laundering conditions using an automatic washing machine. While the procedure includes several options, it is not possible to include every existing combination of laundering parameters. The test is applicable to all fabrics and end products suitable for home laundering.
3D textiles are three-dimensional structures made with different manufacturing methods such as weaving, knitting, braiding, or nonwoven, or made with alternative technologies. 3D textiles are produced with three planar geometry, opposed to 2D textiles that are made on two planes. The weave in 2D textiles is perpendicular. The yarn is fed along two axis: length (x-axis) and width (y-axis), while 3D textiles also have a perpendicular weave, but they have an extra yarn with an angular feeding (z-axis) which creates thickness. 3D weaves are orthogonal weave structures, multilayer structures, and angle interlocks. 3D textiles have more manufacturing opportunities, various properties, and a broader scope of applications. These textiles have a wide range of applications, but they are most commonly used where performance is the primary criterion, such as technical textiles. Composite materials, manufacturing is one of the significant areas of using 3D textiles.
