Direct Counting Method The essence of the method is to unwind the twist in a yarn until the fibres are parallel to the yarn axis and to count how many turns are required to do his. A suitable instrument has two jaws at a set distance apart. One of the jaws is fixed and the other is capable of being rotated.[…]
Primary Motions In order to interlace warp and weft threads to produce fabric on any type of weaving machine, three operations are necessary: Shedding Separating the warp threads, which run down the fabric, into two layers to form a tunnel known as the shed. Picking Passing the weft thread, which traverses across the fabric, through the shed.[…]
Weaving and Woven Fabric In general terms, a textile fabric may be defined as an assembly of fibers, yarns or combinations of these. There are several ways to manufacture a fabric. Each manufacturing method is capable of producing a wide variety of fabric structures that depend on the raw materials used, equipment and machinery employed and the[…]
Definition of Hydrolysis Hydrolysis is a chemical process in which a molecule is cleaved into two parts by the addition of a molecule of water. One fragment of the parent molecule gains a hydrogen ion (H+) from the additional water molecule. The other group collects the remaining hydroxyl group (OH−). Hydrolysis of Reactive Dye During[…]

We understand behavior when we know that what is caused or made the person do it. We evaluate behavior when we approve or disapprove it. Both understanding and evaluation is a common[…]
Jute is a pure natural cellulosic fibre. Its staple length is so long. It is golden in color. So its processing system is different from other natural fibre like cotton or wool. Its processing mechanism is not so difficult. This process helps to pack the jute slivers properly. The packing arrangement step is crucial in[…]
