 DIFFERENCE BETWEEN COMBED AND CARDED YARNS: Combing and carding are two ways to prepare the raw fiber for spinning. In order to make yarn, the raw fibers need to be fluffed up and aligned prior to spinning. -Carding creates a slightly fuzzier yarn as not as many of the fibers are aligned. -Combing creates a smoother yarn as the fibers are more aligned. Combing is the more expensive process as you have higher waste involved than with carding.

Combed yarn: A yarn that produced from fibers that have been carded (or prepared) & combed. Objects:                 -Combing action is done here.                -Short fiber % is low.                -Quality is better than carded yarn.                -Strength high than carded yarn.                  -Regular structure.                 -twist distribution uniform. Because short fiber % is low than carded yarn its strength high and structure is regular. Combed Yarn

Carded Yarn :   A yarn that produced from fibers that have been only carded but not combed.   Objects:                -Combing action is not done here.                -Short fiber % is high.                -Quality is not better than combed yarn.                -less strength.                -Irregular.   Because short fiber % is high carded yarn strength low and its is irregular. Carded Yarn

                        Classification of yarn: 

            Classification of spinning:

                                           Spinning The process of producing yarn or filaments from fibers or monomers respectively is called spinning.

                                                 Yarn Manufacturing Yarn Manufacturing Technology ========== Spinning Yarn may be defined as a product of substantial length and relatively small cross-section consisting of fiber or filament with or without twist. Yarn Wool

Difference between Natural fiber and man-made fiber: Natural fiber Man-made fiber The fiber which are obtain/got from nature. The fiber which are developed by man. Most of natural fiber Hygienic in nature. Most of man-made fiber are not Hygienic. Length and structure is control by nature. Length and structure is control by man. Or, can be produce as our wish. Production cost is high. Production cost is low than natural fiber. High absorbency. Low absorbency. Its plants depend on natural climates. ...

                                   Cotton Fiber A short description about cotton fiber: Ginning: Ginning is the process by which cotton fiber separate from seed. On based of ginning cotton fiber is two types: 1. Lint 2. Linters Lint : The fiber which are obtained or got after 1 st ginning. These fibers are spinable. Length: >.5” {.5”-2.5”}   Quality: Better. Used for producing yarn. Linters: The fabric which are obtained or got after 2 nd or 3 rd ginning.              -Short, seedy.              -Fibers are can be Broken              -Length: < .5”               -Quality: Inferior    ...

Difference between Hydrophilic & Hydrophobic fiber: Hydrophilic Hydrophobic The fibers which is absorb water is known as Hydrophobic fibers. The fibers which is not absorb water is known as Hydrophobic fibers. Most of natural fibers are Hydrophilic fiber. Most of man-made fibers are Hydrophilic fiber. These are less sustainable. These are more sustainable. This types of fibers attract moisture of the body. This types of fibers repel moisture of the body. This types of fibers are more comfortable than Hydrophobic fibers. This types of fibers are less comfortable than Hydrophilic fibers. These fibers has low intermolecular force. These fibers has high intermolecular force.

Desirable properties of fiber: -Crimp -Luster -Resiliency -Elasticity -Durability -Absorbency -Color -Flexibility -Conductivity -Softness -Pliability -Abrasion Resistance

Essential properties of Textile fibers: -Staple length -Tensile strength -Fineness -Cohesiveness -Uniformity Staple length: Length is an important parameter which is determined the usefulness of textile fiber. When a continuous yarn is to be made out of individual fibers. It should process a considerable length reference to its diameter, otherwise it would not be possible to make a yarn that would hold together the constituent fibers. This is referred to as the length to breadth ratio. The most useful] all fiber should have the length to diameter/breadth ratios of more than 100:1. Tensile strength:  The strength indicates the resistance sustained by fibers, the yarns or the fabrics to break when force is applied to them. Normally strength of a textile fiber is measured in tencion when the fiber is loaeld along its long and ids designated as “Tensile Strength”. The tensile strength of the textile fiber is measured as the maximum tensile stress in force per...

"All fiber are not textile fiber but all textile fiber are fiber". It is true that all fiber are not textile fiber but all textile fiber are fiber. At first we have to know that what is fiber and textile fiber? A materials which is several times as long as its thickness as one of the dedicated hair like portions of the tissues of a plant, animal or other substances is called fiber. On the other hand, the materials or artificial which can be converted into yarn or fabric for clothing & also for domestic & industrials purpose by interlacing or inter-looping are known as textile fiber. Such as catkin and human hair these are fibers but not textile fiber because these cannot be converted into yarn and fabric for clothing and also for domestic & industrials purpose by interlacing or inter-looping that’s why we cannot say all fiber are not textile fiber but all fiber are fibers.

                          Textile fiber The materials at naturals or artificial origin which can be converted into yarn & fabric for clothing and also for domestic and industrial purpose by interlacing or interloping are known as textile fiber. Example: Cotton, asbestos, wool, jute etc. Cotton

                                        Fiber A materials which is several hundred times as longest its thickness as one of the delicate hair like portions of the tissues of a plant, animal or other substance is called fiber. Example: wool, cotton, catkin, human hair, jute etc. coconut husk fiber
