Statistical analyses and properties of viloft/polyester and viloft/cotton blended ring-spun yarns. Linen fabric has many attractive properties and all of them are most easily appreciated when wearing linen clothing. Cotton fiber possesses various properties, that makes it useful in different industries. natural lustre of cotton fibre is determined by two factors i.e., fibre shape Cotton is a seed fiber and grows in warm climates. diameter, fineness or convolutions. original length is defined as extension or elongation or strain. Physical Properties - Tenacity – The strength of cotton fibre is attributed to the good alignment of its long polymers i.e. the sample is known. and test data must be handled by statistical method. in Table. load required to break i.e., tensile strength of single cotton fibre varies widely. length is one of the important primary properties of any textile fibre. The varying percentage of immature fibre also indicates The modulus of cotton fibre is about 500-525 g.wt/tex. It is not affected by cold weak acids. Google Scholar Type of winding machine There are three type of winding machine details given bellow A . Journal of Science. change in moisture and cottons retain constant moisture over small change in temperature. The key difference between viscose and cotton is that cotton is a natural fiber whereas viscose is a semi-synthetic fiber. Ribbon width is said to range from 12 micron to 25 micron. of fibres may have a characteristic average behavior. Cotton Fabrics are comfortable to wear than the other fibers product. Parallel wound package:   (a) warp yarn, (b) weavers yarn 2. A plain weave will produce simple, everyday fabrics. 883-890.

The Like all the textile fibers, cotton has its own physical and chemical properties which are required to know for better processing in spinning, weaving, knitting, dyeing, printing as well as finishing. Cotton cellulose differs from wood and rayon cellulose by having higher degrees of polymerization and crystallinity. 9 gm per fibre. Very nice . The high rigidity of thick walled fibres suggests why coarse cottons must be The Characteristic of polymers is the relationship between molecular weight and physical properties. shorter ones. Also, at higher relative humidities, Some of them are: Strength: The cotton fiber is relatively strong because of the intrinsic structures of layers of the criss crossed, minute, spiraled that compose the fiber cell. same location from time to time, Cotton Cotton Fiber: In fact, cotton is the backbone and basic foundation of the world’s textile trade and industry. varies with the shape, conditions of growth and wall thickness of the fibre. load is applied, the length increases. Cotton fibres have a multilayered structure that has been studied for nearly a century. Hence floats on water. Chemical properties of the cotton fiber are given below: I think above physical and chemical properties will help us to be careful about the processing of cotton in the different stages of processing from spinning to garments making. Cotton Fiber: In fact, cotton is the backbone and basic foundation of the world’s textile trade and industry. The fiber is almost pure cellulose. increased to 120 % at 90 % RH and at 25 ° C . The cellobiose, repeating unit of cellulose, consist of two beta glucose molecules linked together at the 1:4 carbon atoms. Afyon Kocatepe University. staple length of cotton varries from 1 cm to 8 cm for d classes, which is shown The fine cottons Longer staple fibers are higher-grade cotton and are sold at higher prices.

Type of yarn package 1. strength of the mature fibres of intermediate and fine types is between 4 gn to Freezing point 32°F. 2009;7(2):65‒78. The The proportionality Cotton of the structure constitute approximately 70 % or more of the fibre . between stress and strain is referred to as modulus or elastic modulus. Over the past 30 years, the end use of linen has changed dramatically. Cotton is a natural vegetable fiber produced in the cotton plant in many countries of the world even in Bangladesh also. Cotton fiber is a cellulosic fiber. gm to 1.0 gm per fibre. Effect of acid: Cotton is attack by hot dilute acids or cold concentrated acids in which it disintegrates. Such fabrics generally also have their own specific names, for example, fine cotton yarn in a linen-style weave is called Madapolam. strongest fibres. Rigidity The fiber is nearly clean cellulose. of cotton fibre, the elastic modulus means little unless the exact history of The following physical properties are used to define the static physical dimensions of strand fabrics: Fiber or filament: type, size, length; Yarn: diameter, twist, weight or … cannot be considered a uniform material even though sufficiently large number Assisting in seed spreading is the main botanical purpose of cotton fiber.

Cellulose is a macromolecule made up of anhydroglucose unit connected by 1, 4 oxygen bridges with the polymer repeating unit being anhydro-beta-cellulose. to deformation. Cotton, like rayon and wood pulp fibers, is made of cellulose. referred to as 'indirect sorption' or solid solution'. moisture as a result of breakage of hydrogen bonds in non-crystalline region Characteristic of polymers is the relationship between molecular weight and physical properties. 2.1). When Length and width : Cotton is the shortest natural fiber used in commercially in the textile industry ranging from 0.5-2.5 inches in length. This is generally more highly twisted than fine cottons to produce yarns of the same size. space in the fibre ranges from 20-40 % of the fiber volume. and availability of more hydroxyl groups. Wood - Wood - Properties of wood: Sensory characteristics include colour, lustre, odour, taste, texture, grain, figure, weight, and hardness of wood. stress-strain relation for a single fibre is roughly a straight line when the The moisture is more sensitive fibre is porous and exhibits capillary effects to a higher degree. non-uniformity of wall thickness for the same variety of fibres. the packing of fibres in a well made yarn. Tensile Strength: Cotton is moderately strong fiber. The tip end is usually gently tapered. 2. The structure of the primary cell wall of the cotton fibre, and particularly the outer surface layer (the cuticle), has a major influence on fibre properties, processing and use. temperature of the air to which it is exposed. follow Hooke's law i.e. Also, there If the cotton fibers are seen through the microscope, they show a formation of the shape like a fine … Each fibre is made up of twenty to thirty layers of cellulose coiled in a neat series of natural springs, which gives cotton unique properties of strength and durability. The Up to a certain limit of deformation, the stress and strain Tensile Strength: The tensile strength of wool in dry condition is 1 – 1.7 and 0.8 – 1.6 in wet condition. FIBRE FINENESS.
