Abstract
Till last decade manufactures were trying hard to inbuiltfundamental requirements like strength, abrasion resistance, elongation,evenness, imperfection, colour fastness, good sew ability, etc., Nowwith the passage of time and advancement on the technology front, usersrequirements have become more demanding. For life of apparel or any othertextile articles, fulfilling the fundamental and basic requirements are notgoing to serve the desired purpose. There is a need to protect the seamsfrom ultra- violet rays that can damage the threads. Once seam strength islost, stitched articles will no longer be able to survive.
Think of marine boats, awnings and articles serving in opensky for years. Under typical climatic conditions such articles are well takencare as far as quality and life at their fabric are concerned. In this paper wepresent a discussion on importance of UV repellency finishing on sewingthreads and application of UV repellence finish on sewing thread and itsdevelopments and testing of respective finishing.
Introduction
Sewing thread is considered to have been the first textilematerial. History tells us that some 25000 years ago sewing threads weremade by the persons living in caves and jungles by rubbing and twisting togetherthe long fur fibres pulled from animal skins. The crude threads, bymeans of needle, were used to join animal skins to form the primitive clothingof the early civilization. In the sewing thread one of the most revealingfactor is, responsible for degrading the strength of seams is theexposure of articles to sun, the main source of ultra-violet rays for throughdurability of seams. The sewing thread has to have excellent resistance toultra violet light. Ultra Violet Rays are a part of spectrums ofelectro-magnetic radiation emitted by sun. The severely damage the thread itexposed continuously for long periods.
