Grotex Texstar for Sizing
Textile warp sizing, also known as tape sizing, of the warp yarn is essential to reduce breakage of the yarn and thus production stops on the weaving machine. On the weaving machine, the warp yarns are subjected to several types of actions i.e. cyclic strain, flexing, abrasion at various loom parts and inter yarn friction.
grodex Texstar (for sizing),inproves the strength — abrasion resistance — of the yarn and the hairiness of yarn decreases. The degree of improvement of strength depends on adhesion force between fiber and size, size penetration as well as encapsulation of yarn.
Woven fabrics are two-dimensional bodies consisting of fibers in the form of threads intersecting at right angles (the warp and weft), produced using the shed-forming method. The warp threads undergo repeated stress during each insertion of the weft and at each change of shed.
The warp threads undergo stress in the form of yarn - metal abrasion when the weft thread is pushed by the reed, by yarn - yarn abrasion during the change of shed, and by cyclic stretching processes. The warp threads are normally unable to withstand these extreme stresses, and must therefore be provided with a protective coating. - the siting agent - that adheres to the fiber, forming an abrasion-resistant, elastic film.
Adavantages
grodex Texstar Sz provides protective coating - the siting agent - that adheres to the fiber, forming an abrasion-resistant, elastic film.It makes the yarn resistant to the frictional processes that take place during weaving.
Improves Protruding of fibers to adhere to the main body of the yarn, thereby preventing neighboring warp threads from catching or entangling. grodex Texstar over all increases the tensile strength of the thread of about 20 % and increases the crucial strength at the weakest points
