Manmade /Artificial fibres

fiber Man-made fibres are fibres in which either the basic chemical units have been formed by chemical synthesis followed by fibre formation or the polymers from natural sources have been dissolved and regenerated after passage through a spinneret to form fibres. These fibre came to success when the researchers obtained a product by condensation of molecules presenting two reactive aminic groups with molecules characterised by two carboxylic reactive groups.

Pressing Equipments/Machinery

apparel It is possible to press samples of light clothing, such as dresses, blouses and night dresses, onversatile unit equipped with a hand iron. However, if the samples are of constructed garments,while most of the simple under pressing operations can be performed with a hand iron, there are still several operations which require the specialized machines in the factory. This is especiallyrelevant to top pressing where to most of the operations are performed on special purpose machines.

Warp let-off and fabric take-up

fabric weaving Warp let-off system has a frequency converter, which is intended for letting off from warp beam or feeding unit. The drive is mounted either on the weaving machine or on a frame positioned behind the weaving machine. The let-off starts with a machine running signal; the speed of the let-off motor is controlled by a proximity switch mounted on the whip roller system and an internal speed memory. An alarm signal switches the weaving machine off in case of over tightened warp or any other error.

Notches

apparel After all the pattern pieces are cut, you can begin marking each piece. It provides “road signs” showing where to sew and press. It will also speed your sewing time when done correctly. Marking will take only a little time and is not as tiring as using the tracing wheel or placing the pattern back on the fabric to look for a lost detail. There are 2 types of notches Pattern notches and centre notches.

Carton Strapping

apparel A wide variety of tool and machine systems are available to strap cartons, eventual choice often being determined by through put and/or cost. Generally the easiest way to strap cartons is with a semi automatic machine that has a cycle time per strap of just over 2.0 seconds. Automatic and automated machines are frequently used for continuous bulk usage. Polypropylene (PP) strapping is an economical packaging solution designed for light to medium duty unitizing, palletizing and bundling.

Pattern Grading

apparel Pattern Grading is the process where by patterns of different sizes are produced from the original master pattern. This process can be performed manually or automatically by a computerized system. Patterns are graded according to size charts which present the sizes and the average measurements of the population group for which the garments are intended.In order to produce garment that fits various body types and sizes, the pattern pieces must be increased or decreased geometrically to create a

Synthetic Fibers

fiber The synthetic man-made fibers include the polyamides (nylon), polyesters, acrylics, polyolefin, vinyl, and elastomeric fibers, while the regenerated fibers include rayon, the cellulose acetates, the regenerated proteins, glass and rubber fibers

Miscellaneous Fibres

fiber Fibres which do not logically "fit" under other classifications such as natural, manmade, mineral etc. such novaloid, carbon, poly-phenylenedibenzimidazole polyimide fibres etc. are categorized under miscellaneous fibres.
