Modification of weaving process by integrated sizing-weaving loom Mohammad Zakaria, Md. Shakhawat Hossain, S.M. Bin Rafat Hasan Chowdhury, M.A. Sakib, Ronju Miah Abstract Typical weaving system has been introduced a number of difficulties of fabric manufacturing. Some faults such as hard sizing, light sizing, excessive warp strain, warp crossing etc. is occurred by typical sizing which could not be identified before weaving. If the sizing process is carried out on loom, sizing parameters would be adjustable according to demand. A miniature sizing unit was integrated with an ordinary power loom. The miniature sizing box was made of wood which consist of electric heater. A hot air dryer was used to dry the warp yarn after sizing. A conventional loom was used to weave the fabric of specification with PPM (Picks Per Minute) near to 160. Satisfactory weaving efficiency (about 90%) was achieved for weaving with proposed integrated sizing-weaving loom. Here warp yarn entered in weaving zone just after sizing, thus ends breakage rate would be reduced. This study also proposed a new weaving process which abolish sizing machine from typical weaving flow chart. Keywords: Sizing, Tensile strength, Weaving, Loom, Weavers beam etc. 1. Introduction It is good news for Bangladesh that the textile industry have a stable position on knit sector in the world market. It is predictable that knit sector will bloom in large scale for country within near future. This success may be possible due to its lower initial invest and no back process complexity. Small entrepreneur capable to run a small project with a few number of machine and a narrow floor space using a lower amount of power supply. This is known that, many Bangladeshi entrepreneur already established large weaving project, but due to lack of power supply (electricity and gases) it has not able to run successfully. At present country already suffering for gas and electricity crisis [1] . In modern weaving industry to support a sizing machine at least 150 looms is required which causes huge amount of electricity consumption. Some industrial area in India, many investor have lost their least profit and business due to shortage of power supply [2] . Weaving process has been introduced chronological development from its beginning [3] . A lot of research works was completed on elimination of sizing process. Most of the attempts was use of high qualified warp (high strength, U% etc.) and modification on shedding system [4 , 5] . But none of them successfully run being today. Sizing is a very complex process and difficult to maintain accuracy. A lot of parameters affecting the sizing performance of warp yarn during weaving [6] . If improper and uneven sizing is applied on yarn, they are considered as wastage which is not recoverable [7] . It is possible to minimize the typical sizing complexity, by individual machine parameter setting system. Sizing parameter can be change according to fabric quality demand, which is not possible by weaving as well as typical sizing process. This property may be facilitating the production of diversifying product. Online quality control cannot be possible by typical weaving system. If any fault is occurs in the production process, it is require terminating the whole system. But in integrated sizing-weaving system, individual machine may be responsible for individual problem, remaining are unaffected. Modification of weaving process by on-loom sizing is an assembly, where the sizing is carried out just before weaving. It means that one miniature sizing unit for one loom. It will be possible for a small entrepreneur to establish a small weaving plant with a few numbers of integrated sizing- weaving looms.
