Color The color of cotton fiber could be white, creamy white, bluish white, yellowish white or grey. Tensile Strength Cotton is moderately strong fiber. It has a tenacity of 3-5 gm/den. The strength is greatly affected by moisture; the wet strength of cotton is 20%, which is higher than dry strength.
RE Tensile strength of Cotton, Nylon, Polyester fiber? btrueblood (Mechanical) 9 Aug 13 10:54 Fiber ultimate strength is called "tenacity", and is usually quoted in grams/denier or g/d.Fiber ultimate strength is called "tenacity", and is usually quoted in grams/denier or g/d. Denier is a linear mass density. Wikipedia has data for typical cotton fibers, and you should be able to find the others with a bit of googling (I'm being more vague also, because there are about as many types/kinds of nylon as there are kinds of wood, and expect you will find even more variation from the generic term "polyester"). The tenacity for manufactured fibers will actually go up as the fiber denier is decreased (i.e. smaller fibers), just like with spring wire.You will find useful information in these links tensiontech/papers/papers/deep_mor/... nap.edu/openbook.php?record_id=11268&am...1Googling Technora fiber strength took me to the manufacturers website (first hit in list) one click on "comparing aramids" too me here teijinaramid/aramids/comparing-aram... which gives the tensile strength as 3.4 GPa. Chris DeArmitt Expert consulting & training phantomplastics1The same table gives polyester (PET) as 1.1 GPa and nylon (PA6 and PA6,6) as 0.9 GPa. Chris DeArmitt Expert consulting & training phantomplasticsHuh. So nylon is 4x weaker than Kevlar and Technora. Pretty impressive. I still can't find any data for cotton fibers.Wikipedia gives tensile strengths for cotton fiber. Just enter cotton in the search box. But, it will give you figures in grams/denier, so you will have to convert.Nice article here http://cp.literature.agilent/litweb/pdf/5991-0...1A Google search for "strength cotton fiber MPa" gives the answers you want in the first hit. http://cp.literature.agilent/litweb/pdf/5991-0... Answer 1.1 GPa. Really, can people at least make a real effort to use Google before asking? Chris DeArmitt - PhD FRSC Materials Consulting & Training phantomplasticsI already Googled it about twenty times before using different keywords. Sorry, but I guess you're better at Googling stuff than I am. And thanks :)No worries! Googling may be more of an art than I'd suspected.

Cotton Fiber Strength. Fiber strength is measured by breaking the fibers held between clamp jaws. It’s reported as grams per tex, which is the force in grams required to break a bundle of fibers one tex unit in size. A tex unit is equal to the weight in grams of 1000 meters of fiber. Nep. A …
The strength is greatly affected by moisture; the wet strength of cotton is 20%, which is higher than dry strength. Nylon The high tensile strength of nylon makes it ideal for heavy fabrics used in home decor.Tensile Strength, Ultimate 82.7 MPa,Elongation at break is 50 %.Tensile Modulus 2.93 GPa.
The main focus of this chapter is on the tensile failure of cotton fiber, or the reaction of the fiber to an axial force that can ultimately cause fiber breakage. The tensile behavior of a cotton fiber is manifested in all aspects of cotton handling such as cotton ginning, spinning, weaving, and knitting.Cited by 2
A wide variety of tensile strength of cotton options are available to you, such as tensile testing machine, universal testing machine, and strength testing machine. You can also choose from free samples, paid samples. There are 769 tensile strength of cotton suppliers, mainly located in Asia.
Cotton fabrics have the lowest tensile elongation, since the cotton yarn itself also has the lowest tensile elongation of only 4.45%. The tensile elongation of cotton fabrics is 16%. The highest elongation is observed in the fabric in twill 2/2 weave.Cited by 12
Key aspects related to cotton fiber strength testing. In this section of the chapter, the two main critical aspects related to cotton fiber tensile behavior are 1. The type of testing single-fiber strength versus bundle (beard) strength. 2. The moisture–strength relationship of cotton fibers. 7.11.2.Cited by 1
Statistical models have been developed for the prediction of tensile strength of polyester/cotton (52:48) blended woven fabrics. The models have been developed based on the empirical data obtained from carefully developed 234 fabric samples with different constructions using 15, …Cited by 1
Physical Properties of Cotton Physical properties of wool fibers are given below Color The color of wool fiber could be white, near white, brown and black. Tensile Strength The tensile strength of wool in dry condition is 1 – 1.7 and 0.8 – 1.6 in wet condition. Elongation at break Standard elongation is 25 – 35% and 25 – 50% in wet condition.
The staple fiber properties of TEIJINCONEX are shown in Table 3. A high tenacity (HT) type with greatly improved tensile strength is also available. Table 3 Fiber Properties of TEIJINCONEX

1.1 This test method covers the determination of ( 1) the tensile strength or breaking tenacity of cotton fibers as a flat bundle using a nominal zero gauge length, or ( 2) the tensile strength or breaking tenacity and the elongation at the breaking load of cotton fibers as a flat bundle with 1/8 …
Tensile properties of cotton fibers are influenced by the internal structure of the fibers. Cotton fiber is 98% cellulose. Cellulose molecule is synthesized from sucrose, the major type of sugar which can be found in the sap of cotton plant.

Comparison of tensile properties of textile fibre. Rayons made until the 1950s had a micellar structure, which results in a low-wet-modulus and a low strength. The modal rayons, which include polynosic fibres, are fibrillar in texture, and are stiffer, and closer to cotton in properties, than earlier rayon fibres.
Tensile strength and tearing strength are discussed separately. A relation between cloth tensile strength, yarn strength and the parameters of cloth construction and yarn construction is suggested. Tearing strength is shown to be dependent mainly on the spacing and strength of the threads being torn ...
Tensile Strength of fibers. To determine the tensile strength of nay fiber, it is tied to a hook at one end and weights are slowly added to the other end until the fiber breaks. Since peptide bonds are more easily hydrolyzed by bases than by acids, therefore wool and silk are affected by bases and not by acids.
Transport testers. It is observed that the static tensile test overestimates tensile strength and breaking elongation. The static tensile strength and breaking elongation decrease after winding but the dynamic elongation of cotton, polyester and 67:33 polyester/cotton yarn increases after winding.
