A Design of a Cyclic Universe (I)

Authors: Harry Fitié
Comments: 16 Pages.

The model of the universe is defined as an isolated system. It is represented by a coherent, directed, random network. The network consists of nodes, connections and a demiurge who randomly modifies these connections according to the urns model. We show that is possible to manipulate the entropy in this isolated system by changing the protocol by which the demiurge modifies connections. Two protocols result in expansion with increasing entropy. Four protocols result in contraction with decreasing entropy. A combination of these protocols results in a cyclic universe. What is further demonstrated is that - in spite of the random behavior of the demiurge - there is a form of self-organization in the network. The structure of the expansion protocols triggers the so called Matthew Effect. Even at a level of maximum entropy the network is relatively more populated by complex structures (measured by the number of connections) than by simple ones. Finally, it is shown that a state of "omniscience" is impossible. The information content of the model universe is much lower than the information that is needed to describe its state. Within this universe an entity that is omniscient cannot occur.

Effect of Stitch Length on Physical and Mechanical Properties of Single Jersey Cotton Knitted Fabric

Authors: Elias Khalil, Md. Solaiman
Comments: 4 Pages.

The physical and mechanical properties of knitted fabric can be changed due to use of various count of yarn, type of yarn (ring, rotor, and compact), quality of yarn, stitch length / loop length, structural geometry, fiber composition of yarn etc. This study focused on the various stitch length effect of grey single jersey. With an increase in stitch length, the dimensional properties like CPI, WPI, GSM, thickness & tightness factor will be decreased for all the structures; while comfort properties like air permeability & water absorbency will be increased. Again shrinkage & spirality will be decreased with increased stitch length at grey stage. Other properties such as bursting strength, abrasion resistance & pilling resistance improved with increased stitch length. Though all the tests for fabric properties were carried out for grey stage, there properties can considerably vary after further finishing of the fabrics. As finishing is mandatory for fabric production, so now-a-days, these kinds of tests are carried out after finishing stage & proper controlling is done according to desired quality. Sometimes, controlling of some properties of finished fabrics are beyond our trial. In that case, analysis of fabric properties at grey stage can help us to take various control & corrective actions when necessary.

Consequences of Enzyme Rinse on Physical Properties of Knit Garments

Authors: Md. Solaiman, Md. Mostafizur Rahman, Elias Khalil, Joy Sarkar
Comments: 5 Pages.

The use of enzymes in the textile chemical processing is rapidly gaining globally recognition because of their non-toxic and eco-friendly characteristics with the increasingly important requirements for textile manufactures to reduce pollution in textile production. Furthermore, the use of enzymes results in reduced process times, energy and water savings, improved product quality and potential process integration. Variation of knit fabric and enzyme concentration is taken to do this project. The aim is to know the effect of enzyme concentration on the physical properties of knit garments of various constructions. In this project 0.4 g/l and 0.5g/l enzyme concentration is taken to wash Single Jersey and Rib fabric. Then to see the effect of enzyme concentration on the physical properties of Single Jersey and Rib fabric some tests like GSM, Bursting strength,Dimensional Stability and Pilling are done. The results of before and after enzyme wash is compared to know the effect of concentration of enzyme on the physical properties of Single Jersey and Rib fabric. After enzyme wash GSM of the fabric increases, Dimensional Stability and Bursting strength decreases and pilling formation on the fabric surface also decreases.

Effect of Gauge Variation of Circular Knitting Machine on Physical and Mechanical Properties of Cotton Knitted Fabrics

Authors: Faisal Abedin, K. M. Maniruzzaman, Ahmad Saquib Sina, Elias Khalil
Comments: 6 Pages.

This paper deals with the results of an investigation of various gauges of circular knitting machines with a view to producing same single jersey fabric with different parameters. All parameters including machine diameter, stitch length, yarn count, yarn lot, yarn tension etc. but gauges are used for this work is different. Even dyeing has been done at the same time on the same machine by stitching one with other, finishing parameters and processes are also same and done at same time as well to minimize the effects of other variable which can be responsible for changing the physical and mechanical properties like finished width of the fabric, finished GSM (Grams per Square Meter), shrinkage, spirality, bursting strength etc. This is done for finding only the effects which actually affects the fabric properties. Finally the findings or results are as expected with some variations with the results that are thought theoretically.

Efficiency Losses Calculation and Identify Causes of Losses of Circular Knitting Machine During Knit Fabric Production

Authors: Md Solaiman, Elias Khalil, Mostafizur Rahman, Joy Sarkar
Comments: 4 Pages.

This thesis deals with a major problem of production loss of a knitting industry. The knitting machine has to stop when defects occurred and then faults are corrected, which results in time loss and efficiency loss. Not only that the knitted fabric may be rejected if quality requirements are not met. An effective monitoring is required to avoid defects and to avoid productivity and quality losses. The study identifies two main categories of defects (average time required for correcting defects and machine down time) are responsible for reducing productivity. The thesis reflects that due to yarn breakage machine stopped for seen minutes per days, for maintaining machine stopped for two hours per month, for needle breakage six minutes per day and for technical problem machine stopped for several times

Evaluation of Physico-Mechanical Properties of 1×1 Interlock Cotton Knitted Fabric Due to Variation of Loop Length

Authors: Elias Khalil, Md Solaiman, Joy Sarkar, Md Mostafizur Rahman
Comments: 5 Pages.

The Physico-Mechanical properties of knitted fabric can be changed due to use of various count of yarn, type of yarn (ring, rotor, and compact), quality of yarn, Loop length / Stitch length, structural geometry, fibre composition of yarn etc. This study focused on the various Loop length effect of grey interlock knit structure. With an increase in Loop length, the dimensional properties like CPI, WPI, GSM, thickness & tightness factor will be decreased; while comfort properties like air permeability & water absorbency will be increased. Again shrinkage & spirality will be decreased with increased Loop length at grey stage. Other properties such as bursting strength, abrasion resistance & pilling resistance improved with increased Loop length. Though all the tests for fabric properties were carried out for grey stage, there properties can considerably vary after further finishing of the fabrics. As finishing is mandatory for fabric production, so now-a-days, these kinds of tests are carried out after finishing stage & proper controlling is done according desired quality.

Line Balancing for Improving Apparel Production by Operator Skill Matrix

Authors: Md. Mazharul Islam, Md. Tanjim Hossain, Mohammad Abdul Jalil, Elias Khalil
Comments: 6 Pages.

In this modern world, fashion & styles are changing frequently. The emergence of fast changes in fashion has given rise to shorten production cycle time in the garment industry. To meet the dynamic customer demands of momentous quantities in shorten lead time, assembly line production systems are used, where the garment components are assembled into a finished garment through a sub-assembly process. So in the era of product customization, the optimal usage of resources especially the available facilities & operators who are adding the value of product is important. Therefore the assembly line has to be planned in much more flexible way. This paper deals with the maximum utilization of manpower in labor intensive assembly lines. The objective is to accurately delegate workers to the various operations required to complete the product based on their skill & experience so as to achieve the highest level of productivity and delivery as per planned target. The experimental result showed meaningful improvement in productivity as compared to the existing system.
