Simplex Frame and its Parts

spinning spun-yarn yarn The chief function of simplex frame is the attenuation of sliver. Insertion of protective twist in order to hold the fine strand of sliver. Winding of roving into a package that can be transported, sorted, donned on ring spinning machine.After carding the cotton is passed through draw frames. The draw frame draws the cotton inot thick strands.These are then spun inot thinner strands on hte simplex frame spindles. The output of the simples frame is fed to the ring frame spindles which complete t

Establishing and Running a Proper Canteen

apparel spun-yarn Because a balanced diet plays an important role in improving employees’ health, and boosting productivity, maintaining a good canteen can contribute to a productive work environment. Factories are increasingly investing in this area to ensure that productivity levels remain high throughout the work day. An ILO study on workers in developing countries found that food of poor quality (e.g. iron deficient) causes a productivity loss of $ 5 billion per annum in South East Asia, while providing a goo

Staple Yarn Spinning

spinning spun-yarn yarn The larger part of staple fibre, approx. 33 mio tons are processed in short staple spinning. This part of the spinning industry therefore is of great significance in the world of textile production.

Ring Spinning

spinning spun-yarn yarn The Ring Spinning is the most widely used form of spinning machine due to significant advantages in comparison with the new spinning processes. The ring spinning machine is used in the textile industry to simultaneously twist staple fibres into yarn and then wind it onto bobbins for storage. The yarn loop rotating rapidly about a fixed axis generates a surface referred to as "balloon". Ring frame settings are chosen to reduce yarn hairiness and the risk of glazing or melting the fibre.

Sizing

fabric spun-yarn weaving Sizing is a complementary operation which is carried out on warps formed by spun yarns with insufficient tenacity or by continuous filament yarns with zero twist. It is done with an aim of improving yarn smoothness and tenacity during the subsequent weaving stage. The sizing methods change depending on the type of weaving machine used, on the yarn type and count, on the technician's experience and skill, on the kind of material in progress.

Garment Trimming

apparel finishing spun-yarn In total all the trimmings used for the garment cab be substantial cost item and so their selection and use require careful considerations. There is no point in improving materials utilisation if the savings made are thrown away by using expensive tapes as stay tapes. The professional approach is: sufficient for the intended purpose no more.

Blow Room Functions

spinning spun-yarn yarn Blow room is the starting of the spinning operation where the fibre is opened, cleaned, mixed , micro dust removed and evened thus passed to carding machine without increasing fibre rupture, fibre neps , broken seed particles and without removing more good fibres. The basic functions of blow room are opening, cleaning, dust removal, blending and evenly feeding the material on the card.

Functions of Carding

spinning spun-yarn yarn Carding is a mechanical process that breaks up locks and unorganised clumps of fibre and then aligns the individual fibres so that they are more or less parallel with each other. Carding can also be used to create blends of different fibres or different colours. Carding plays a crucial role in all spinning cycles particularly in the woollen spinning cycle, in which it incorporates different functions, all essential in order to obtain the level of quality required of the product.

Draw frame Functions

spinning spun-yarn yarn Carded Slivers are fed into the Draw-Frame and are stretched/Straightened and made in to a single sliver. Also fibre blending can be done at this stage. The cans that contain the sliver are placed along the draw-frame feeder rack, usually including eight pairs of cylinders (each pair is above the space occupied by a can),the lower cylinder is commanded positively, while the upper one rests on the lower one in order to ensure movement of the relative sliver that runs between the two.

Roving

spinning spun-yarn yarn The input of roving frame is silver that comes from draw frame section where only parallel of comber sliver. In roving section reduce the linear density of draw frame silver by drafting. After reducing the linear density the silver is transfer into roving (a thin form of rope). This is first stage where twist is inserted for making a yarn in spinning mill. The output of this section is roving which is wind on a bobbin and this is suitable for further process. Here in this section describes
