Designs in which the ornament consists chiefly of small, detached spots or figures are employed in nearly all classes of yarn and yarn combinations, for dress fabrics, fancy vesting, and other textures in which elaborate figure ornamentation is not desired.
Loom is machine or device which is used to produce woven fabric. It is the central point of whole process of cloth production. In other word, a loom is a mechanism or tool used for weaving yarn and thread into textiles. Looms vary in a wide assortment of sizes. They come in huge free standing hand looms, tiny hand-held frames, to vast automatic mechanical tools. A loom can as well pertain to an electric line construction like that of a wiring loom. The main task of looms is to clutch the twist threads under pressure to enable the progress of interweaving of the woof strands. The loom's system and exact form can differ to some extent; however it still performs the basic application.
Twill weave is a kind of weave that repeat on three or more ends and picks and produces diagonal line on the face of fabric.
In a regular twill the diagonal line or twill line produces at 45 degree angle with the horizontal.
Concept:
The most characteristic of twill is that they have diagonal lines on the cloth.
In weft knitting, the loops are formed across width of the fabric Each weft thread is fed , more or less at right angles to the direction in which the fabric is produced.Weft-knit fabrics may also be knit with multiple yarns, usually to produce interesting color patterns.
Huckaback weave has a number of warp and weft threads with long float, making the fabric soft and moisture absorbent,and plain weave threads ensuring firmness of structure.
Hairiness is characterized by the quantity of freely moving fibre ends or fibre loops projecting from a yarn or textile fabric (woven, knitted or non woven fabrics).
In term of measurement Hairiness corresponds to the total length of the protruding fibres in unit length of one centimeter.
Bedford cord : this weave produces the longitudinal warp lines in the cloth with fine sunken lines between.
Name: Bedford cord, named after the town of Bedford in England.
Weave is the method or process of interlacing two yarn or similar material so that they cross each other at right angle to produce woven fabric . Traditionally, denim fabric are 3/1 warp-faced twill fabric made from a yarn dyed warp and an undyed weft yarn and the warp yarn is indigo dyed ,however this twill weave fabric is also available in textures, such as cross hatch and jacquard etc. The textures selected during the design development process for upcoming seasons are chosen with the wash treatment in mind, such as enzyme, acid etc and look & performance requirement of finish product.

Fancy yarns are special products of spinning, twisting, wrapping, texturing and knitting, etc. The demand for yarns with structural and/or optical effects is due to the special aesthetic and high decorative appeal to the woven, knitted materials, and other textiles as well. Textile materials that are produced using yarns with effects find applications in normal and high fashion clothing.
A woven cloth is formed by the interlacement of two sets of threads, namely, warp and weft threads.
These threads are interlaced with one another according to the type of weave or design. The warp
threads are those that run longitudinally along the length of the fabric and the weft threads are those that
run transversely across the fabric. For the sake of convenience the warp threads are termed as ends and
the weft as picks or fillings.

Weaving 2016-17 Industry in Bangladesh.Sadia Textile
The textile and clothing industries provide the single source of growth in Bangladesh's rapidly developing economy. Exports of textiles and garments are the principal source of foreign exchange earnings. By 2002 exports of textiles, clothing, and ready-made garments (RMG) accounted for 77% of Bangladesh’s total merchandise exports. In 1972, the World Bank approximated the gross domestic product (GDP) of Bangladesh at USD 6.29 billion, in 2014, the GDP stood at USD 173.82 billion, growing by almost 27 times in a matter of four decades. Bangladesh's exports industry alone comprised USD 31.2 billion in FY 2014-15, 81.69% of which was made up by ready-made garments. On its own, the knitwear sector encompasses 39.83% of total exports—a staggering USD 12.43 billion. Bangladesh is, second only to China, the world's second-largest apparel exporter of western brands. Sixty percent of the export contracts of western brands are with European buyers and about forty percent with American buyers. Only 5% of textile factories are owned by foreign investors, with most of the production being controlled by local investors.

A seam is a joint of two pieces of fabric in producing a three -dimensional shape of a garment.
Properties of good seam are,
= Smooth fabric joints
= No Missed or Uneven stitches
= No damage to the material being sewn
= Achievement of strength, elasticity, Durability, security and comfort
= Comfortable while garment is in use
SEAMS DESIGNATION
Each stitched seam is designed numerically by five digits:
0.00.00 refers to the CLASS, 1-8;
0.00.00 refers to the material configuration,
01 to 99;
0.00.00 refers to needle penetrations, material configurations, 01-99.
Seam Classification:
According to British Standard 3870: 1991, seam is classified as-
Class 1- superimposed
Class 2- lapped
Class 3- bound
Class 4- flat
Class 5- decorative/channel
Class 6- edge neatening
Class 7- applied
Class 8- others
* Formed by lapping two pieces of component, they are produced with minimum of two pieces of component.
* One component is limited on one end and the other is limited on the other end. The limited edges of these two components are put in opposite directions.
* Used for: main seaming of denim jackets, jeans, and overalls. Fabrics that will not ravel, unlined garments, side seams of shirts, joining lace to another fabric, attaching patch pockets, decorative finish

Two major classes of warp knitting m/cs:-
1. Tricot warp knitting m/c
2. Raschel warp knitting m/c.
Features Tricot warp knitting m/c:
In the past, tricot m/cs mainly employed bearded needles with a pressure bar
Tricot m/cs have a gauge expressed in needle per inch and chain link numbering 0, 1, 2, 3, 4 etc. generally with three links per course
Their sinkers, which are joined to each other at the front and back, never move clear of the needles as they combine the functions of holding down, knocking over and supporting the fabric
The fabric is drawn-away towards the batching roller almost at right angles to the needles bar
Pilling is formation of little balls of fibers (pills) on the surface of a fabric which is caused by abrasion in wear.

Low power architecture of logic gates using adiabatic techniquesnooriasukmaningtyas
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.

The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
1. 3.2.10 Rearranged Twills
1. Concept
Rearranging a weave means taking single thread or
groups of threads from the base weave and
rearranging them in a different order. See Fig. 3.36
2. Base twill
Fig. b:
Fig. a:
Fig .a : the picks are rearranged in groups of
two in sateen
Fig .b :a different rearrangement in warp
direction in groups of two
3. 2. They are constructed as
follows:
a) Select base weave.
b) Determine a plan for rearrangement.
c) Rearrange threads: ends or picks.
4. 3. Example:
Base twill the new order of warp
threads is 7,8; 5,6; 3,4; 1,2.
Base twill rearranged twill in the given order
5. 4. Applications
Many characteristic fabrics can be made by
using rearranged twills due to its versatility.
6. 3.2.11 Shaded twill
1. Concept
The shaded twill represents a gradual transition
from the twill with weft effect to warp effect, and
vice versa. It is used mostly in Jacquard weaving
for large-pattern fabrics. See Fig.3.37
9. 2. Weave drawn
Formulae to calculate the repeats:
Ro = Rob (Rob-1 )
Ry = Ryb
Where: Ro---new weave repeat; Rob---the base
weave repeat.
10. 3.3 Satin/Sateen weaves
Derivatives
1. Reinforced sateen
It is constructed by using the original sateen
as the base and adding overlaps. See Fig. 3.38
Adding a warp float at the right of the original one
11. Example
Fig. 3.39 shows a 11/8
reinforced sateen which is
often used for worsted fabric
called satin back gabardine.
The face of the fabric has a
twill appearance and back
has a satin appearance.
12. 2. Shaded sateen
Like the shaded twill, the shaded satin represents
a gradual transition from the sateen with weft
effect to the satin with warp effect, and vice
versa. See Fig.3.40
Ry=Ryb=5
RO=Rob(Rob-1)=5×4=20
