Three heddle-rods for weaving twill

The warp-weighted loom is a simple and ancient form of loom in which the warp yarns hang freely from a bar, which is supported by upright poles which can be placed at a convenient slant against a wall. Bundles of warp threads are tied to hanging weights called loom weights which keep the threads taut. [1]

Contents

Evidence of the warp-weighted loom appears in the Neolithic period in central Europe. It is depicted in artifacts of Bronze Age Greece and was common throughout Europe, remaining in use in Scandinavia into modern times. Loom weights from the Bronze Age were excavated in Miletos, a Greek city in Anatolia. [2]

The warp tension needed on a loom is roughly proportional to yarn diameter, and loom weights must be positioned in an even, level row, with all the threads hanging nearly straight down, for smooth weaving. This means that the shape of a loom weight limits a loom to certain thread counts, and the mass of the loom weight is related to the yarn used. This means that loom weights can be used to calculate the density and other properties of the fabric made on them. [3]

History

The warp-weighted loom may have originated in the Neolithic period. The earliest evidence of warp-weighted looms comes from sites belonging to the Starčevo culture in modern Serbia and Hungary from late Neolithic sites in Switzerland. [4] This loom was used in Ancient Greece, and spread north and west throughout Europe thereafter. [5] It was extensively used in the north among Scandinavian people. [6] For yet unknown reasons, the warp-weighted loom diminished in popularity and disappeared from common use. [7] The arrival of mechanized looms and industry may have contributed to this decline. It remained in use longest in Scandinavia; researcher Marta Hoffman found warp-weighted looms still in use on an isolated island off the coast of Norway and among the Sami of Norway and Finland in the 1950s. [8] Today, the warp-weighted loom is used as a hobby and in historic preservation societies. [9]

Elements of a warp-weighted loom

A warp-weighted loom has two upright posts (C); they support a horizontal beam (D), which is cylindrical so that the finished cloth can be rolled around it, allowing the loom to be used to weave a piece of cloth taller than the loom, and preserving an ergonomic working height. The warp threads (F, and A and B) hang from the beam and rest against the shed rod (E). The heddle-bar (G) is tied to some of the warp threads (A, but not B), using loops of string called leashes (H). So when the heddle rod is pulled out and placed in the forked sticks protruding from the posts (not lettered, no technical term given in citation), the shed (1) is replaced by the counter-shed (2). By passing the weft through the shed and the counter-shed, alternately, cloth is woven. [10]

The warp-weighted loom is used in a near-vertical position, and the fabric is woven from the top of the loom toward the ground. This allows the weaver to walk back-and-forth while working, so that wider cloth can be woven than is practical on a ground loom. On Ancient Greek vase paintings, two weavers, most often women, are shown working side-by-side on the warp-weighted loom. [9] This is unusual because most other looms require a resting position of standing or sitting. According to Artemidorus, if one dreams of a warp-weighted loom it means an upcoming journey. If one dreams of any other type of loom, one should expect rest. [11]

Additionally, extra warp thread can be wound around the weights. When a weaver has reached the bottom of the available warp, the completed section can be rolled around the top beam, and additional lengths of warp threads can be unwound from the weights to continue. This frees the weaver from vertical size constraints. [10]

<span class="mw-page-title-main">Loom</span> Device for weaving textiles

A loom is a device used to weave cloth and tapestry. The basic purpose of any loom is to hold the warp threads under tension to facilitate the interweaving of the weft threads. The precise shape of the loom and its mechanics may vary, but the basic function is the same.

<span class="mw-page-title-main">Weaving</span> Technology for the production of textiles

Weaving is a method of textile production in which two distinct sets of yarns or threads are interlaced at right angles to form a fabric or cloth. Other methods are knitting, crocheting, felting, and braiding or plaiting. The longitudinal threads are called the warp and the lateral threads are the weft, woof, or filling. The method in which these threads are interwoven affects the characteristics of the cloth. Cloth is usually woven on a loom, a device that holds the warp threads in place while filling threads are woven through them. A fabric band that meets this definition of cloth can also be made using other methods, including tablet weaving, back strap loom, or other techniques that can be done without looms.

<span class="mw-page-title-main">Woven fabric</span> Textiles formed by weaving

Woven fabric is any textile formed by weaving. Woven fabrics are often created on a loom, and made of many threads woven on a warp and a weft. Technically, a woven fabric is any fabric made by interlacing two or more threads at right angles to one another. Woven fabrics can be made of natural fibers, synthetic fibers, or a mixture of both, such as cotton and polyester.

<span class="mw-page-title-main">Power loom</span> Mechanised loom powered by a line shaft

A power loom is a mechanized loom, and was one of the key developments in the industrialization of weaving during the early Industrial Revolution. The first power loom was designed and patented in 1785 by Edmund Cartwright. It was refined over the next 47 years until a design by the Howard and Bullough company made the operation completely automatic. This device was designed in 1834 by James Bullough and William Kenworthy, and was named the Lancashire loom.

Ikat is a dyeing technique from Southeast Asia used to pattern textiles that employs resist dyeing on the yarns prior to dyeing and weaving the fabric. In Southeast Asia, where it is the most widespread, ikat weaving traditions can be divided into two general groups of related traditions. The first is found among Daic-speaking peoples. The second, larger group is found among the Austronesian peoples and spread via the Austronesian expansion to as far as Madagascar. It is most prominently associated with the textile traditions of Indonesia in modern times, from where the term ikat originates. Similar unrelated dyeing and weaving techniques that developed independently are also present in other regions of the world, including India, Central Asia, Japan, Africa, and the Americas.

<span class="mw-page-title-main">Tablet weaving</span> Weaving technique

Tablet weaving is a weaving technique where tablets or cards are used to create the shed through which the weft is passed. As the materials and tools are relatively cheap and easy to obtain, tablet weaving is popular with hobbyist weavers. Most tablet weavers produce narrow work such as belts, straps, or garment trims.

<span class="mw-page-title-main">Warp and weft</span> Two constituent threads of woven cloth

In the manufacture of cloth, warp and weft are the two basic components in weaving to transform thread and yarn into textile fabrics. The vertical warp yarns are held stationary in tension on a loom (frame) while the horizontal weft is drawn through the warp thread. In the terminology of weaving, each warp thread is called a warp end ; a pick is a single weft thread that crosses the warp thread.

<span class="mw-page-title-main">Double cloth</span> Woven textile type

Double cloth or double weave is a kind of woven textile in which two or more sets of warps and one or more sets of weft or filling yarns are interconnected to form a two-layered cloth. The movement of threads between the layers allows complex patterns and surface textures to be created.

Another emerging silk producer is Tamil Nadu in the place in where mulberry cultivation is concentrated in Salem, Erode and Dharmapuri districts. Hyderabad, Andhra Pradesh and Gobichettipalayam, Tamil Nadu were the first locations to have automated silk reeling units.

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 it 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.

<span class="mw-page-title-main">Shed (weaving)</span>

In weaving, the shed is the temporary separation between upper and lower warp yarns through which the weft is woven. The shed is created to make it easy to interlace the weft into the warp and thus create woven fabric. Most types of looms have some sort of device which separates some of the warp threads from the others. This separation is called the shed, and allows for a shuttle carrying the weft thread to move through the shed perpendicular to the warp threads. Which threads are raised and which are lowered are changed after each pass of the shuttle.

Band weaving refers to the hand production of narrow woven fabric. This fabric may be called tape, band, inkle, strap, belt, back strap, trim, and more. It can be accomplished on a variety of types of looms, including inkle, band, tape, backstrap, and rigid heddle looms. Hole and slot heddles are also designed to weave bands. Depending on which loom is used, the material could be warp-faced or a balanced weave.

<span class="mw-page-title-main">Heddle</span> Loom component that acts as a weft passage

A heddle or heald is an integral part of a loom. Each thread in the warp passes through a heddle, which is used to separate the warp threads for the passage of the weft. The typical heddle is made of cord or wire and is suspended on a shaft of a loom. Each heddle has an eye in the center where the warp is threaded through. As there is one heddle for each thread of the warp, there can be near a thousand heddles used for fine or wide warps. A handwoven tea-towel will generally have between 300 and 400 warp threads and thus use that many heddles.

Textile manufacturing is one of the oldest human activities. The oldest known textiles date back to about 5000 B.C. In order to make textiles, the first requirement is a source of fibre from which a yarn can be made, primarily by spinning. The yarn is processed by knitting or weaving to create cloth. The machine used for weaving is the loom. Cloth is finished by what are described as wet process to become fabric. The fabric may be dyed, printed or decorated by embroidering with coloured yarns.

<span class="mw-page-title-main">Reed (weaving)</span> Part of loom

A reed is part of a weaving loom, and resembles a comb or a frame with many vertical slits. It is used to separate and space the warp threads, to guide the shuttle's motion across the loom, and to push the weft threads into place. In most floor looms with, the reed is securely held by the beater. Floor looms and mechanized looms both use a beater with a reed, whereas Inkle weaving and tablet weaving do not use reeds.

<span class="mw-page-title-main">Waffle fabric</span> Type of woven or knit fabric

Waffle fabric, also known as honeycomb fabric, has raised threads that form small rectangles. It can be made by either weaving or knitting. Waffle weave is a further exploitation of plain weave and twill weave which produces a three-dimensional effect. The combination of warp and weft floats creates the structure. It is woven partly on tabby areas surrounded by ridges of long floats. The weave consists of warp and weft floats arranged around a plain weave center. The warp and weft threads are interlaced and floating in a way that creates small square ridges and hollows in the fabric in a regular pattern.

<span class="mw-page-title-main">Leno weave</span> Weave in which two warp yarns are twisted around the weft yarns

Leno weave is a weave in which two warp yarns are woven around the weft yarns to provide a strong yet sheer fabric. The standard warp yarn is paired with a skeleton or 'doup' yarn; these twisted warp yarns grip tightly to the weft which causes the durability of the fabric. Leno weave produces an open fabric with almost no yarn slippage or misplacement of threads.
