in the main drafting field, aprons are used to guide the fibres drafting limits fibre type drafting limit carded cotton >= carded blend >= combed cotton and blended yarns medium fineness >= fine yarns>= synthetic fibers >= spindle arrangement the spindle arrangement consists of the following parts tread...
ring spinning is the oldest of the present day spinning processes. the fibre material is supplied to the ring-spinning machine in the form of roving. the fibre mass of the roving is reduced by a drafting unit. the twist inserted moves backwards and reaches the fibres leaving the drafting unit. the fibres...
length. the reason is that longer fibres are not only soft to touch but also last longer. the best way to estimate if the cotton material you want to purchase is made with long-staplefibres is by holding it up to light. ideally, it should not be transparent and there should be no gaps standing out...
properties of textile fibres . length and length variation length is an important parameter which determines the usefulness of a textile fibre. when a continuous yarn is to be made out of individual fibres, it should possess a considerable length with reference to its diameter, otherwise, it would not...
