DESCRIPTION 7749 FLAT I OVER DYE DENIM FABRIC Technical Area The present invention; It is about fabrics called denim or blue jeans.

The invention particularly focuses on knitwear fabrics obtained by the arrangement of warp and weft. or the formation of loops similar to a towel, and thus with denim fabric, which provides the appearance and wearing comfort of the fabric. is relevant. Thanks to this 'product, comfort in wearing, flexibility, knitwear or towel-like double Ply fabric feature is that the contact of indigo dyed yarns with leather or other clothing Prevention, convenience, comfort, etc. It provides many positive features such as

Description of the State of the Art Fabrics called denim or blue jeans are generally defined as cotton, in various unit weights, produced from yarns such as polyester, nylon, viscose, Iycra usually warp yarn dyed blue indigo, weft undyed (raw), various They are fabrics woven in braids.

Denim name comes from the Rhone valley of southern France “Tissu de Nimes”, the name Blue jeans On the other hand, it comes from the phrases “Blue de Genes” from the Italian Riviera. The diversity of demand in the 1950s, 1960s, manufacturers of different washing techniques and denim activated the colors that can be applied to the fabric. At the end of the 1980s, body-hugging skinny jeans made of Iycra blend denim fabric started to spread. Jean's popularity in all segments, haute couture also pushed its creators to new works. Yves Saint Laurent, in 1970, wearing his jeans took the podium. Fashion designers such as Calvin Klein, Armani and Valentino followed him.

Blue Jean is produced from denim fabric dyed with indigo. Jean, cut, sew, ready to be packed after going through the stages of washing, rinsing, drying and ironing becomes. Washing, which is one of the most important of these processes, is a different color to the fabric. and gives effects. Depending on the desired effect, jeans, after prewash Indigo is a dye produced from the leaves of the plant "Indigofera tinctoria".

Indigo, whose use dates back to MD 1600, is widely used in India, Indonesia, China and It has been found in Africa. Indigo, which is blue, has gray, green and red tones. Paint manufacturers of dyes in different colors with the properties of indigo they are doing. However, the attempts made so far have been unsuccessful, Fading could not be ensured and it could not be prevented from penetrating the fiber. Indigo at once Since it does not penetrate the thread, dipping the threads into the indigo boat can achieve the desired tone. continues until done. The more repeated immersion in the boat, the darker it becomes. color is obtained. After the paint process is finished, dead paint, thanks to washing techniques taken from the thread.

The fabric is first purified from the substances necessary for weaving and apparel. Next It has an abrasive effect and prevents the paint from adhering to the fabric again.

In the next step, the contrast between blue and white by chemical treatment is increased. In the bleaching process, the chemicals used are increased and the color changes to ice blue. returns. In addition, in the stage called “rodeo”, it will be done in special cabins made of fabric. It is ensured that certain areas are bleached by spraying. A solution for denim fabric and its production is given. However, in clothing to the user A flexible solution that offers comfort is needed.

As can be seen in Figure-1 and Figure-, the unit 'knitting report' of the fabric which is the subject of the invention (pattern) front and back views. 10 warp threads (1) and 15 wefts per unit thread (2) makes different movements. A1, A2, A3 Weft yarns in woven fabric (2) represents. 91, Ç2, 533 Representing the warp threads (1) in woven fabric It consists of cotton threads. The total number of warp wires is 7220 wires. warp threads (1) with deep blue indigo and sulfur dye mixtures in a warp dyeing machine. it is dyed, harvested and brought to weaving. Weft yarns (2) are 2 pieces of 30 combed 44 dtex It consists of Core Spun (3.5 elastane drawn) and 1 piece of 16 ring carded yarns. Flat process is applied to woven raw fabrics in finishing (Fabric brushing, incineration, causticisation, washing, neutralization, drying, widening, finishing and shrinkage operations). Warp density for reed: 37.5 ±2 pcs/cm, mechanical woven fabric weft Density: 33 ±2 pcs/cm, raw cloth weft density: 34 ±2 pcs/cm, manufactured fabric weft density: 39 ±2 pcs/cm, the weight of the finished fabric (3 times at 60 degrees) The elasticity of the washed fabric is 40 ±4 %. fabric knitting like knitted fabrics in the weft direction and diagonal directions due to its structure. there is yawning. Yarn counts, fiber types, weft or warp density, color or Shrinkage can be diversified without being limited to finishing processes.

With this process, the type name becomes 7749 Fiat. If you over-dye this fabric If it is to be done, in the finishing process, at the washing stage or after various textile Dyeing processes are done with dyes (sulphur, indigo, etc.). With this process, the type name is 7749. it is over dyed. Here, color and finishing processes are not limited. can be diversified. warp numbered on top - warp number 94 on bottom, A2 weft 16 Ring carded weft Warps number 99 are placed on the bottom, A3 weft 30 combed 44 dtex core spun weft. 4. numbered warps are placed on the bottom, A4 weft 30 combed 44 dtex core spun weft. at step 5 warp numbered on top - warp number 92 on bottom, A8 weft 16 Ring carded weft Warps numbered 97 are placed on the bottom, A9 weft 30 combed 44 dtex core spun weft. 10. numbered warps are placed on the bottom, A1O weft 30 combed 44 dtex core spun weft. 11th. - Warps numbered Ç7 - Ç9 - Ç10 on the top - Warps numbered Ç3 - 98 on the bottom, weft A13 - Çs - Ç9 warp on top - Ç10 warp below, A14 weft 16 ring carded scarf is thrown. In step 15, T1 - T2 - T3 - T4- Çö - Ç? - Numbered Ç8 - Ç9 spun yarn is thrown.

As seen in Figure-3 Warp: 20 Combed Cotton + 20 Combed Cotton, Weft 1: 16 Ring Carded, Weft 2: 30 Combed Cotton 44 dtex Core Spun (3.5 elastane shot) Warp density: 37,5 pcs/cm reed density, Weft density: 34 pcs/cm raw fabric. It is given as 39 pcs/cm ready fabric.

As seen in Figure-41, respectively, warp thread (1), weft thread (2), warp, weft thread (1,2) connection, rigid/straight weft thread (2) passing under multiple warp threads (1) The loop appearance formed by the elastomeric weft thread (2) in connection with the warp thread (1) views are given.

A denim fabric consists of a front side and a back side. With weft threads (2) It consists of a knitting pattern in which the warp threads (1) are woven together. The warp threads (1) are dyed indigo and/or sulfur. Weft threads (2), at least one It should consist of a straight/rigid weft and/or an elastomeric weft.

In the example shown in figure-1 and figure-2, two elastomeric weft yarns (2) are combined with a rigid/flat yarn. is listed. But the yarns can be arranged in different ways without going out of the concept.

For example; The ratio of elastomeric yarn to rigid/straight yarn can be 221 or 12. 1:3 or 3:1 etc. preferable. The proportions of the threads must be regular or throughout the fabric. it doesn't have to be the same.

The weave of the fabric is from the lower part of the warp thread (1) to the upper part. Lower parts of it are shaped by the rigid/straight yarn passing behind its warp and the loop is defined as. Loop formation is seen in figure-3 and figure-4. tops, the rigid/straight yarn is shaped by passing over its warp and the connected parts is defined as. Solve threads on top (X) and weft threads on top (.). is indicated. Number of warp threads (1) 5-50 Ne (British Numbering system fineness unit) can be chosen between The number of all the warp threads through which the loops pass, It is not necessary that the color or the slub effect be the same. Warp through each loop The number of threads is at least 5 Ner. Warp number without changing the concept it can change.

The number of wefts in which the rigid threads pass through the back surface should be at least 5 pieces. in the figure In the example, the loops pass under 9 warp threads and one warp thread (1) being passed over. Rigid/flat yarns (16 ring carded) of 9 warp yarns (1) passes under and over one warp. This layout concept can be changed without breaking.

According to the example in the figure, the loops of the rigid / flat yarns are compared to the elastomeric weft yarns (2). is less tense. loops make the fabric look like a knit fabric. it provides. If these loops are made of soft cotton threads, they will be soft and fabric with a comfortable back surface is obtained. This is the back surface of the fabric. Another benefit of the loops is to prevent the warp threads (1) from coming into contact with the skin. This is important as the warp threads (1) are indigo dyed. Indigo dyed yarns If it comes into contact with the wearer, the dye may come off the skin or clothing. the loops extend in the cross direction to the warp and weft threads (1,2). Similarly, the connection Its parts extend in the cross direction to the warp and weft threads (1,2). in your template rigid/flat yarns may be different from elastomeric yarns. For elastomeric yarns Knitting pattern and/or yarn selection weft and warp with other kinds of selected pattern With respect to the threads (2,1), stretching in the cross direction is allowed. Many benefits can be obtained by using a cross template. First, the warp thread when dyed with indigo, using cross pattern weaving classic denim to fabric It gives the look and at the same time, it preserves the touch and feel of the knitted fabric. Adds more knit fabric properties. In addition to the arrangement and order of the warp and weft threads (1,2) look, feel, weight, stretch, etc. of the fabric. other defining features is the cyclicity of the warp threads (1) or the weft threads (2) with each other. The cyclic values of the warp threads (1) before drawing are approximately 20-60 warp threads. / cm. After the fabric has been treated and after home washing, the preferred The warp density obtained is approximately 25-75 warp threads/cm. House wash at 60 °C It is made, then dried and left to condition for eight hours. These tests are ASTM D. approximately 25-70 warp threads /cm (3 house) before drawing, even if later after demolition). If desired even more, the warp density after weaving is 28- It can be 80 threads/cm, (after 3 house washes) it will be 30-85 threads/cm.

In general, weft yarn (2) and warp yarn (1) density measurements are 65% humidity ( ± 5% ) and It is done in °C (± 2%) conditions. We can define the weft density in a similar way to the warp density. After weaving before pulling the weft density is approximately 28-80 threads/cm. 30- After 3 house demolitions It becomes 96 threads/cm. Preferred weft density before drawing after weaving 35-85 yarn/cm. After 3 home washes, it is 40-90 threads/cm. If more requested after weaving, 35-75 threads/cm before spinning, 40- after 3 home washes It is 80 threads/cm. Warp and weft yarn density is only knitted fabric behavior. it does not give the feature, but also gains different weights.

In the concrete example, the average number of warp threads passing through the loop is one its ratio to warp frequency is approximately between 0.1-1.0. Also from the loop part The ratio of the passing warp yarns (1) to the average weft number is between 1-25.

Another point is the thickness of the weft and warp threads (2,1). Because elastomeric yarns It will be synthetic or Core spun. Synthetic yarn fineness as denier fineness unit are defined, warp and rigid weft yarns are defined with Ne. Figure-1, figure-2 and figure-3r such as warp, rigid weft and elastomeric weft yarns (2) may have different thicknesses and elastomeric yarns may have smaller thickness than rigid/flat yarns.

In the example; The warp thread number is preferred between Ne 5 - Ne 50. in the example rigid/flat yarns are preferred between Ne 8 - Ne 80. Example: elastomeric yarns It can be preferred between approximately 15 - 50 Ne or 40 - 200 denier. if desired 60 - 100 denier can also be selected. the thickness of the yarns in the original concept. We can gain many benefits by choosing For example; thickness of rigid/flat yarn If it is greater than the thickness of the elastomeric thread, we will better hide the loop sections and We reduce the feeling. Choosing the right thread thickness also feel like classic denim or knit fabric, and its weight feature, shrinkage affects their values etc.

Figure-1 and figure-2 are two different aspects of the original concept. fabric two woven can be thought of as having. The first weaving is generally from the front of the fabric, the warp tightly knitted from yarns (1) and elastomeric weft yarns (2) occurs. The second weaving generally consists of the back surface and the warp threads (1) and the It consists of rigid weft yarns (2) woven in the same way. This rigid weft yarn (2) has a lower part and consists of the upper part. Bottom part, behind the rigid weft thread (2) warp thread (1) occurs by passing. The upper part is rigid when the weft thread (2) passes over the warp. occurs. As seen in the figure, each loop passes under 9 warps, but different In one example, this number may change.

PROCESS STEPS: Warp threads (1): The first step of the process is the warp yarn (1). This step is the choice of thickness or warp. may include frequency. Generally, the choice is indigo dyed solvent yarn (1). Drawn warp The yarns (1) are dyed as warp or rope.

Rigid / straight weft yarns (2): In this step, rigid/d'unless weft yarn (2) is supplied. This step can involve all aspects of the yarn.

Yarn fineness, shrinkage ratio, elasticity, color, weft density, twist value, fiber type, etc. not angry with.

Elastomeric weft yarns (2): This step represents the step associated with the elastomeric weft yarn (2). This step of each thread may include aspects. Thread fineness, shrinkage, elasticity, elastane number, color, weft density, twist value, fiber type etc. not angry with.

Knit, pattern: This step is to determine the template. The template is selected, at least one rigid/d-free yarn is at least one elastomeric thread is set. Rigid/flat yarns are 'upper and lower' according to the determined pattern. wicker formation behind/over warps to create rows of sections like it passes.

Weaving: According to the determined pattern/pattern, in the cycles determined with ç'ozg'u and weft yarns weaving is done.

Fabric shrinkage and finishing processes: This step is about shrinkage of the fabric after weaving. Elastomeric yarns, rigid/d pulls more than yarns (loop with rigid/straight weft yarns on the bottom of the fabric) to create shapes). Do not Pull; from fabric loom occurs when removed. In addition, the shrinkage process also affects the fabric throughout the finishing process. applicable. If the finishing process of the fabric will be over-dye dyeing in various colors The finishing process goes through various dyeing and shrinkage processing steps accordingly.

A fabric has a first weave and a second weave. The first woven fabric is the front side, includes warp threads (1) and tightly woven elastomeric weft threads (2). Second is the back side of the woven fabric, again with warp threads (1) and loosely woven consists of rigid threads. The second weaving warp and elastomeric on the back of the fabric it covers the threads, it is difficult to see and feel these threads on the back.

A woven fabric with weft and warp threads (2.1), the upper part of the weft threads (2) It is stretched over the selected warp threads (1) to form extended below. The second weft threads (2) have more shrinkage than the first weft threads (2). has the ratio. The first weft threads (2) are knitted more tightly than the second weft threads (2). has.

The method of producing a fabric; It is like figure-1 and figure-2. Here is the unit report of the pattern It is explained according to the order of the weft. Unit report to all warp and weft threads (1,2) is being implemented. Connection types of warp threads (1) and weft threads (2), side their appearance and loop formation are shown in figure-3 and figure-4. Loose threads on top (X) and weft threads are indicated as (.) at the top. Here, rigid weft or elastomeric The connection of the wefts with the warp threads (1) is given as an example.

In addition, fabric production includes one of the water applications; mercerized, caustic, over dyeing, bleaching, hand stripping, sandblasting, stone washing, printing, embroidery, brushing, etching etc. It also includes the tailoring stage in ready-to-wear. At least one warp yarn dyed into warp or rope (1), rigid/straight weft yarns (2) and/or elastomeric weft yarns (2), according to the determined pattern, wicker formation behind/over the warps to form the row at least one rigid/straight Yarn, rigid/straight over at least one elastomeric yarn Yarns, loops determined running crosswise to the warp and weft yarns (1,2) created according to the template/pattern determined to be weaving in the frequency The ratio of warp and weft yarns (1,2) and/or average number to one warp density Warp threads (1) passing through the loop part between 0,1-1,0 and/or pulling The frequency values before the warp yarns are approximately 20-60 warp yarns / cm. (1) and/or after weaving the weft density is about 28-80 threads/cm before pulling An over dyed denim fabric is formed, which contains weft yarns (2) between

Warp allowing stretching in the cross direction in relation to the weft and warp threads (2,1) and the weft threads (1,2) extending in the transverse direction.
