Protein Fibre Properties Natural protein fibres are of animal origin. These are those fibres in which the fundamental chemical structure is composed of amino-acids joined in poly peptide chain. All protein fibres comprise the elements, carbon, hydrogen, oxygen, and nitrogen. Wool comprises sulphur as well. In each protein fibre these elements are combined in diverse[…]
Definition of Drying After leaving the size box, the wrap sheet gets impregnated with wet size paste to the extent of about 90% – 140% of its own weight. The process of drying involves complete removal of the moisture from the size paste and at the same time retaining the water in the yarn. This[…]
Definition of Pirn A pirn or quill is a weft bobbin that is placed inside a shuttle in shuttle weaving. As the shuttle travels back and forth across the width of the shuttle loom, the weft yarn is unwound from the pirn through the eye (for ordinary shuttle) or slot (for automatic shuttle) of the[…]
Polyester is defined as a manufactured fibre in which the fibre forming substance is any long-chain synthetic polymer made of at least 85% by weight of an ester of a sub-aromatic carboxylic acid comprising, but not confined to dimethyl terephthalate units and parasols hydroxyl benzoate units. Physical Properties of Polyester Tenacity Polyester filaments and staple[…]
Cellulose acetate is prepared by heating cellulose with acetyl anhydride, glacial acetic acid and sulphuric acid at low temperature. It is a continuous filament and can be made desired diameter staple, length and crimp. To make staple fibre is cut by cutting unit and crimped.

This method is universally adopted and is suitable for large-scale operations. In this method, many warp yarns as per requirement are assembled in the form of a continuous sheet, sized and then wound onto a weaver’s beam. These operations are supported by auxiliary operations such as separation of ends, measuring warp length, marking into cut[…]
Definition of Silk Silk is called the queen of fibres. It is a natural fibre (Protein) obtained from the cocoons of the silk silkworm. It is a continuous natural filament fibre. Definition Of Wool Wool is also a natural fibre obtained from sheep and other animals like goats, rabbits, camels, etc. It is 100% natural,[…]
Definition of Textile Sizing Sizing is the intermediate process of weaving preparation. The yarn after being warped is sized or coated with a thin film of adhesive. The purpose of sizing the yarn is to improve its weave-ability. A single unsized yarn is incapable of withstanding the strains of weaving and also affects the loom production and efficiency. Hence[…]
Definition of Sizing Ingredients The sizing’s fundamental objectives can be achieved only by impregnating the yarn with the appropriate size mixture consisting of various ingredients in suitable proportion. Each ingredient should impart a particular property to the yarn. Accordingly, there are two types of ingredients, namely the primary and secondary ingredients. The primary ingredients are essentially[…]
Simplex Machine is used in the spinning mills. For Ring yarn Simplex machine is necessary. Simplex machine is the machine which converts the drawn sliver into roving form. Simplex process is the previous process of ring spinning process. A slight twist is given onto the roving. We can find different faults in the speed/roving/simplex frame. They[…]
