Abstract | ||||||||||||||||||||||
Finally, the weft delivery of the RIEMCHENTRANSPORT was replaced by FOUMISSEUR. In order to find a solution of this problem is investigating the factors affecting the width fabric in the direction of warp and weft. The study of the weft direction has a significant impact on this characteristic, namely weft yarn tension and the weft yarn length in weft feeder. The methodology of this research depends on experimental and analytical approach. It is found that there exists an inverse relationship of weft yarn tension and direct relationship of weft delivery length with tape width. Moreover there is an inverse relationship between warp yarn tension and tape width. This research involves the study of the problem that exists in most of the factories, which produce narrow fabrics, especially on the Needle Narrow Weave Machines (NFRQ). This is problem that the width fluctuation for these fabrics. This sector is considered one of the most important sectors of industrial fabric because of its multiple uses that affect industrial economy, whether linked to the textile or other industries. These tapes are used in the manufacture of medical bandages, normal or adhesive, apparel requirements of elastic tape, tapes of the process of decorative embellishment clothing or other uses like special types of electric cables and so on. | ||||||||||||||||||||||

And the width of the narrow fabrics is one of the most important factors affecting on optical quality defects on machines. For example wear of the fabric edges, inadequate safety guidance, incalculable change in the mechanical properties like tensile strength and elongation and other properties. The narrow fabric (tape width) is affected by other factors like from warp direction as weft yarn tension and weft delivery length and from the weft direction as warp yarn tension as revealed in figure (1-1).

3 - OBJECTIVES OF RESEARCH: 1- To study the Weft Delivery Length as an effect property of Tape Width. 2- To study the Weft Yarn Tension as an effect property of Tape Width. 3- To study the warp Yarn Tension as an effect property of Tape Width. 4-FACTORS EXAMINED THROUGH THE RESEARCH 4-1: Constant Specifications: 4-1-1: Warp Material: (polyamide 6.6) - 67 dtex. 4-1-2: Weft material: (polyamide 6.6) - 67 dtex. 4-1-3: Machine: Needle narrow weave machine (NFRQ). 4-2: Variable Specifications: 4-2-1: Weft Yarn Direction. 4-2-1-1: Weft yarn tension. 4-2-1-2: Weft Delivery length. 4-2-2: Warp Yarn Direction. 4-2-2-1: warp yarn tension. 5- RESULTS & DISCUSSION 5-1: Relationship between The average warp yarn tension (cN) and Tape width (mm). Figure (1-5) showsRelationshipbetweentheaveragewarpyarntension (cN) andtapewidth(mm). When the average warp yarn tension increases, the width tape also decreases. This implies that there exists an inverse relationship between the average warp yarn tension and tape width. Through the following in Equation (1). Y=50.6-0.03X r =-0.9 Equation (1) When the average warp yarn tension is increased by increasing the weight of gravity on the warp beam, it leads to the decrease the tape width as figure (1-4). It is attributed to the decrease the average warp yarn tension and this will lead to increase warp crimp and thus increase the width tape.

Figure (1-6) shows Relationship between the weft delivery length (m.min-1) and tape width (mm). When the average weft delivery length increases, the width tape also increases. A direct relationship is found between the weft delivery length and tape width. Through the following in Equation (1). Y= 7.22+0.63X r= 0.96 Equation (1). Width tape = the weft delivery length – weft crimp. Sincetheamountweft crimp isfixed, thiswilltoincreasetheweftdeliverylengthandultimatelyincreasethewidthtapealso.

5-3: Comparison Between the average weft yarn tension (cN) and Tape width (mm). Figure (1-7) shows Relationship between the average weft yarn tension (cN) and Tape width(mm). When the average weft yarn tension increases, there is a decrease in width tape. Through the following in Equation (1). Y= 50.3 -0.05X r = -0.98 Equation (1). Aninverserelationshipisconsideredtobepresentbetweentheaverageweftyarntensionandtapewidth.Whentheaveragewarpyarntensionincrease, attributedtoincreasewarp crimp, thiswilldecreasetheweft crimp andthuscausethedecreaseinthetapewidth.

5-4: Comparison Between Machine speed (min-1) and Tape width (mm). Figure (1-8): shows the comparison between Machine speed (min-1) and Tape width (mm). When Machine speed increases, the Tape width also increases which shows a direct relationship. Through the following in equation (1). Y= 49.2 +0.0009X r = 0.99 Equation (1). But this result reveals that the machine is incorrectly set because with the increase in the machine speed the tape width should not change, this implies that this result is due to a defect on a weft delivery.

Figure (1-9) shows the relationship between the crank shaft rotation angle machine (min-1) and warp yarn tension (cN) and weft yarn tension (cN). It is found that fixed relationship between the crank shaft rotation angle Machine and warp yarn tension.
