Defects in dyeing printing and finishing

High viscosity of printing paste, improper profile of squeeze blades, improper cleaning of screens, deposition of thickening agent under or over the screens and frequent stoppages of printing are the normal reasons for choking of screens. Misfitting of the design: Improper tension of screens, worn out thermoplastic coating, deviations in blanket guide controlling system, loose end rings, and pressure roll not working, insufficient quantity of colour in the screen, defective working of printing head, magnetic clamps and inadequate temperature are the normal reasons for misfit of the design. Stains on the garment can be caused by a variety of factors.

This word history has given rise to a number of other terms: Linederived from the use of a linen thread to determine a straight line Liningbecause linen was often used to create an inner layer for wool and leather clothing Lingerievia French, originally denotes underwear made of linen Linseed oilan oil derived from flax seed Linoleuma floor covering made from linseed oil and other materials History[ edit ] A bag of white linen, unopened.

Contains rolls of linen. The discovery of dyed flax fibers in a cave in Georgia dated to thirty-six thousand years ago suggests that ancient people used wild flax fibers to create linen-like fabrics from an early date.

It was used mainly by the wealthier class of the society, including priests. It opens with briefly listing the steps of preparing linen from flax, in a form of questions and answers between Inanna and her brother Utu.

In ancient Egypt, linen was used for mummification and for burial shrouds. It was also worn as clothing on a daily basis; white linen was worn because of the extreme heat. The use of linen for priestly vestments was not confined to the Israelites; Plutarch wrote that the priests of Isis also wore linen because of its purity.

Linen fabric has been used for table coverings, bed coverings and clothing for centuries. The significant cost of linen derives not only from the difficulty of working with the thread, but also because the flax plant itself requires a great deal of attention.

In addition flax thread is not elastic, and therefore it is difficult to weave without breaking threads. Thus linen is considerably more expensive to manufacture than cotton. There is a long history of the production of linen in Ireland.

The Living Linen Project was set up in as an oral archive of the knowledge of the Irish linen industry, which was at that time still available within a nucleus of people who formerly worked in the industry in Ulster.

In Decemberthe General Assembly of the United Nations proclaimed to be the International Year of Natural Fibres in order to raise people's awareness of linen and other natural fibers.

Antiquity[ edit ] When the tomb of the Pharaoh Ramses IIwho died in BC, was discovered inthe linen wrappings were in a state of perfect preservation after more than years. Earliest linen industry[ edit ] Diocletian 's 4th century maximum prices edict showing prices for 3 grades of linen across the Roman Empire The earliest records of an established linen industry are 4, years old, from Egypt, The earliest written documentation of a linen industry comes from the Linear B tablets of PylosGreecewhere linen is depicted as an ideogram and also written as "li-no" Greek: It is not until the twelfth century that we can find records of a definite attempt to systematize flax production.

When the Edict of Nantes was revoked, inmany of the Huguenots who fled France settled in the British Isles, and amongst them was Louis Crommelinwho settled in the town of Lisburnabout ten miles from Belfast.

Basic methods and processes

Belfast itself is perhaps the most famous linen producing center throughout history; during the Victorian era the majority of the world's linen was produced in the city which gained it the name Linenopolis.

Although the linen industry was already established in Ulster, Louis Crommelin found scope for improvement in weaving, and his efforts were so successful that he was appointed by the Government to develop the industry over a much wider range than the small confines of Lisburn and its surroundings.

The direct result of his good work was the establishment, under statute, of the Board of Trustees of the Linen Manufacturers of Ireland in the year Several grades were produced from the coarsest lockram to the finest sasheen. Religion[ edit ] In Judaismthe only law concerning which fabrics may be interwoven together in clothing concerns the mixture of linen and woolcalled shaatnez ; it is restricted in Deuteronomy And that such commands serve both a practical as well as allegorical purpose, perhaps here preventing a priestly garment that would cause discomfort or excessive sweat in a hot climate.Aug 20,  · Finishing Faults/Defects | Different Types of Textile Finishing Faults/Defects with Their Causes.
