Sprang

Sprang is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Sprang rather than just read about it. In short: Sprang is an ancient method of constructing fabric that has a natural elasticity. Its appearance is similar to netting, but unlike netting, sprang is constructed entirely from warp threads.

Key takeaways

  • Sprang belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Sprang to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Sprang from memory before moving on to harder problems.

Reference excerpt

Sprang is an ancient method of constructing fabric that has a natural elasticity. Its appearance is similar to netting, but unlike netting, sprang is constructed entirely from warp threads. Archaeological evidence indicates that sprang predates knitting; the two needlework forms bear a visible resemblance and serve similar functions but require different production techniques. Although examples of sprang have been unearthed from as early as the Bronze Age, sprang was almost entirely undocumented in written records until the late nineteenth century when archaeological finds generated interest in Europe. Museum examples of sprang had been misidentified as knitting or lace until discoveries of ancient examples prompted reexamination of newer pieces. Subsequently, sprang has been identified in a variety of cultures and traditions across several continents. Its practice as a folk art waned during the twentieth century and sprang traditions have disappeared in most locales. Knitting has largely supplanted sprang.

Technique In principle, sprang may be regarded as a practical application of the fiber manipulation techniques used in the children's game known as cat's cradle. Sprang is made by preparing a set of warp threads either on a rectangular frame or between a pair of beams. The crafter then generates a fabric by interlinking the warp threads. Unlike most textile production techniques that add new rows at the end of completed rows, sprang works upon the center of a group of fibers and the material grows inward from both ends with symmetrical top and bottom halves. The crafter must maintain control of the center area or the structure unravels: most sprang worked upon has too many fibers to keep in hand, so rods or sticks maintain the appropriate fiber positions. The fiber manipulation itself is done by the crafter's fingers. Decorative patterns may be generated by regular variations in the fiber crossings. As crossings accumulate the crafter beats the material flat with a stick. Work continues with the material growing from both edges toward the middle until the center band becomes too tight to continue work. The completed fabric is either separated into two identical items or permanently secured at the middle to stabilize the contrary twists. In traditions where two halves of sprang are not severed by cutting, this center seam is a telltale sign of sprang manufacture.

History and uses While the word sprang is of Swedish origin, the technique has been practiced by many cultures around the world. The earliest surviving example of sprang is a hair net, c. 1400 BC, that was recovered from a bog in Denmark. Most archaeological finds of sprang fabric come from the later classical era and the start of the Early Medieval period: locations include Norway (third to fifth centuries AD), Switzerland, Egypt (possibly twenty-second dynasty, also early Coptic), and various Roman sites. Use of sprang has also been conjectured from archaeological recoveries of ancient looms and from depictions in period artwork.

Sprang is also an indigenous needlework technique among the peoples of South America, with the earliest known examples dating from before 900 AD among the Paracas culture and Nazca culture in present-day Peru. Recreation of archeological discoveries continue to inform about the presence and range of sprang in the Americas. Sprang has also been noted in the Middle East, Central Asia, the Indian subcontinent, and North America. Indigenous North American sprang includes woolen scarves by the Ho-Chunk of Wisconsin, and Hopi wedding sashes.

The natural elasticity of sprang makes it suitable for stockings, hair nets, sleeves, bags, scarves, and other purposes where pliant material is required. Most sprang needlework is utilitarian and hence was overlooked by scholars until late in its history, according to needlework historian Catherine Amoroso Leslie:In fact, it was not until the nineteenth century and the discovery of sprang at archaeological sites that it was recognized as a separate and distinct form of needlework. Many museum objects that were wrongly classified as knitting or lace have now been correctly identified as sprang.Following nearly simultaneous archaeological finds in Denmark and Egypt during the 1870s, an example of Coptic sprang brought to Austria in 1882 inspired the management of a factory near Vienna to manufacture sprang hammocks. The Paris World's Fair of 1889 included an exhibit that duplicated ancient sprang, which led to renewed interest in the technique. Traditionally, cultures that practiced sprang had not produced written records of its manufacture or use. Shortly after the Paris exhibition, living traditions of sprang began to be documented. During the 1890s Ukrainian villagers were identified as practicing sprang in the manufacture of women's caps. Soon afterward, local sprang production for various garments was also documented in parts of Eastern Europe and in Denmark. Local European traditions generally endured until the mid-twentieth century. Sprang is, however, largely a historical technique that has been supplanted for most purposes by the later invention of knitting, whose earliest known example dates from the third century AD. During the late eighteenth and early nineteenth centuries a military fashion of decorative sprang sashes in silk known as faja in Spain gained international popularity among generals as a distinguishing ornament of rank. The fashion spread to northern Europe and to North America. George Washington wore a sash made of red silk sprang around the year 1779.

Worked examples

Example 1 — a first encounter with Sprang

Start with the simplest possible case. Write down what Sprang claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Sprang before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Sprang ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Sprang

In research
Sprang appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Sprang in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Sprang is common in secondary-school and first-year university syllabi. It links to neighbouring topics Braids, Lace, Weaving, so understanding it makes those chapters shorter.
In everyday life
Look for Sprang outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
