  1. YARN INTRODUCTION:<\/strong><\/li>\r\n<\/ol>\r\n\u00a0<\/strong>\r\n

    Yarn <\/strong>is a long continuous length of interlocked fibres <\/a>preferably using twist, suitable for use in the production of textiles, <\/a>sewing, <\/a>crocheting, <\/a>knitting, <\/a>weaving, <\/a>embroidery, <\/a>and rope<\/a> making.<\/a><\/p>\r\n \r\n

    A textile yarn<\/strong> <\/a>is an assembly of substantial length and relatively small cross section of fibers and\/or filaments with or without twist\u201d.<\/p>\r\n \r\n

    Thread is a type of yarn intended for sewing by hand or machine. <\/a>Modern manufactured sewing threads may be finished with wax <\/a>or other lubricants to withstand the stresses involved in sewing. Embroidery threads <\/a>are yarns specifically designed for hand or machine<\/a> embroidery.<\/a><\/p>\r\n\"\"<\/a>\r\n

    The most common plant fiber is cotton, <\/a>which is typically spun into fine yarn for mechanical weaving or knitting into cloth.<\/a><\/p>\r\n\"\"<\/a>\r\n

    1. SSpun Yarn Or Staple Yarn<\/strong><\/li>\r\n<\/ol>\r\n \r\n\r\nSpun-staple yarns consist of staple fibers assembled and bound together by various means (usually twist) to produce the required characteristics such as strength, handle and appearance.\r\n\r\n \r\n\r\nShort Staple Yarn: <\/strong>Yarn produced using less than 60mm fibres are called short staple yarn.\r\n\r\n \r\n\r\ni) <\/strong>Ring Spun Yarn:<\/strong>\r\n

      These are produced on the ring and traveller twistsystem from a wide variety of fibre types<\/p>\r\nlength ranges from 15 mm to 50mm.\r\n\r\n \r\n

      The softness changes with respect to twist. Used to produce woven fabrics, knitted fabrics, home textile materials and industrial fabrics.<\/p>\r\n \r\n\r\nIt is of mono-structure, has hairy fibres on its surface. Highly cohesive in structure.\r\n
