Description

1 Jacquard Denim Velvet Fabric Technical Area The invention relates to fibers based on cellulose, primarily cotton, and / or mixtures thereof. formed from warp yarn dyed with indigo dye and dyed or undyed weft yarns 5 Velvet is made by cutting additional weft yarns after weaving, woven in different weave patterns. It is related to the production of jacquard indigo velvet fabric, which also ensures its formation. State of the Art Sportswear is in demand from all segments of society because it is comfortable and can be worn in many different settings. It is being developed and its use is increasing day by day. In recent years, 10 in our country and in the world After disasters that occurred, some of which required staying at home and others requiring not entering homes, this Demand for stylish clothing has increased even further. Clothing made from denim fabrics is among the leading examples of sportswear. Denim products are made from indigo-dyed warp yarn and raw weft yarn, which are composed of cellulose fibers. formed by the weaving of yarn and subjected to various chemical and / or mechanical processes after garment manufacturing. 15 These products are characterized by the creation of various effects through different processes. This product group... Although it is primarily made of cotton fiber and indigo dye, recently different dyes and different materials have been used. Fibers and colored weft yarns have also started to be used. Generally with a 3 / 1 Z weave pattern. Denim fabrics are mostly used to produce trousers. After indigo dye, the most commonly used dye in denim fabric production is 20. These are sulfur dyes. Both of these dyes bind weakly to cellulose fibers using van der Waals and... They are connected by hydrogen bonds. The warp yarn is continuous as a rope or open width. During dyeing, care is taken to ensure that the dye does not penetrate to the center of the yarn. diameter of the dyed part, pre-treatment before dyeing, twist of the yarn, contact with the dye The duration depends on factors such as subsequent processing, dyeing conditions, and the pH level of the float, etc. 25 It varies. If desired, the yarn can also be dyed all the way to the center. It can be provided. As mentioned earlier, different effects can be achieved through various mechanical and / or chemical post-processing steps. Denim products, which can experience color fading, can be used in different garments or in different areas. It should be usable. Some sections believe denim fabric can be used in home textiles, outerwear, and more stylish designs. They want it to be used, or used more frequently, in visible upper or lower garments. Current approaches or product styles are not adequately addressing many of these needs. In previous years, it was mostly classic-cut products, but recently it has become more sporty. One of the fabrics used in cut products is warp velvet fabric. Warp velvet fabrics 2 The weft consists of ground, weft pile, and warp yarns. In weft velvet fabric, the weave repeat is... yarn thickness used in warp and weft, number of warp yarns skipped by the weft pile yarn, weft and The number of threads per inch varies depending on the density of the warp yarn. Weft velvet. In fabrics, cord cutting (cutting the weft / pile yarn) is performed after weaving. 5 processes carried out between the cord cutting process and the garment manufacturing stage or afterwards. The weft yarns cut during the processes merge with other cut weft yarns by distributing them into their fibers, and It forms the velvet (fuzzy surface). The most important post-weaving process for velvet fabrics is cutting the weft pile yarns. This is the process of cord cutting (or wick cutting). The cutting is done using needles and a blade appropriate for the wick width. If it were possible for the needle to pass a few wick lengths without a gap in the machine where the process takes place, 10 This is not possible over longer distances. The wick is either continuous or discontinuous along its entire length. They can be formed and it is possible to continuously cut their warp length. Additional weft It is not possible to create different fuzz patterns by cutting the threads with existing methods. It is not. One type of fabric that is considered elegant and aesthetically pleasing is jacquard fabric, and these 15 These fabrics are mostly used in home textile products such as curtains, covers, and towels. They are durable. It is the most preferred because it retains its shape and is comfortable to use. It is one of the fabrics. Jacquard terry and velvet fabrics are also produced with additional warp yarn. It is common. This type of weaving or knitting uses different colored yarns to create intricate and detailed designs. By creating patterns and images, it provides aesthetic and visual richness, but this 20 The use of these fabrics, especially in sportswear, is quite limited. Recently, there has been a significant increase in demand for sporty-style products, but the type of fabric used for these products... This is not enough to make the group even richer. What is requested and / or designed The type of fabric is insufficient for producing some models, so several different fabrics are used together. Its use is attempted through increased labor and increased resource consumption. 25 Denim products can be used for various purposes, especially in sportswear. In appearance, it is partly fluffy (velvet), elegant and aesthetically pleasing, and resistant to wear and tear. It is not possible to produce high-quality fabric with existing production methods or processes. In conclusion, the problems mentioned above necessitate innovation in the technical field. has brought. 30 3 Brief Description of the Invention The invention aims to eliminate the problems and disadvantages mentioned above and to contribute to the relevant technical field. making improvements, increasing product variety, especially classic and sportswear cuts producing denim fabric with a rich pattern that can be used in many areas. to provide. 5 The purpose of the invention is to create jacquard looms capable of weaving with diverse and rich patterns, using warp yarn. and / or by weaving fabrics where the weft and warp yarns are dyed with indigo dyes, denim Similar to the effects achieved with post-garment processing in fabrics, however... By providing richer visuals during the weaving process, the area is rich in effects and patterns. The goal is to produce denim fabric with a velvet weft. 10 One aim of the invention is to create jacquard weft velvet fabric where the warp yarn is dyed with indigo dye. It is the ability to produce. Another purpose of the invention is to dye weft yarn and / or additional weft yarn with indigo dyes. It is possible to produce dyed jacquard weft velvet fabric. One aim of the invention is to cut the additional weft threads that run along the warp and weft, thus reducing the weft to 15 Beyond creating velvet fabric, it involves creating patterns other than velvet in some areas and adding extra weft in others. The process involves cutting the threads to create velvet. Another purpose of the invention is to perform mechanical and / or chemical post-processing after garment manufacturing. The goal is to reduce the labor and energy required to enhance the product. Another purpose of the invention is to create a blend of cellulose-based fibers and / or other natural and / or synthetic fibers. yarns made from a mixture of fibers and dyed with indigo dye, weft and / or additives Jacquard fabric with additional weft yarn and pattern, using warp and / or weft yarn. One of the aims is to ensure the production of some or all of the additional weft yarns. The goal is to increase product variety by cutting back on yield. Another purpose of the invention is to utilize warp yarn, preferably primarily warp yarn. and / or weft yarn and / or additional weft yarn dyed with indigo and / or sulfur dyes. In jacquard woven fabric, the additional weft threads are either not cut at all, or some of them are cut, or cutting the entire thing to create different aesthetic looks in the denim product group to provide. Another aim of the invention is to enable the production of three-dimensional velvet denim fabric. 30 4 Another purpose of the invention is to use yarn dyed with indigo and / or sulfur dyes. Jacquard with different color fadings and effects due to various mechanical and chemical aftereffects. Our ability to produce denim velvet fabric. Another aim of the invention is to increase the variety of fibers we will use in warp, weft and additional weft yarns. Fabric production, garment manufacturing, or post-garment processes to achieve your desired weight, 5 The aim is to provide a selection that will bring richness of image and color. Another purpose of the invention is to create a fabric dyed with indigo and / or sulfur and / or other dyes. the creation of patterns with or without additional weft yarns and / or the addition of additional weft yarns By cutting irregularly, a three-dimensional jacquard denim velvet fabric is created, with areas of varying textures, both fluffy and smooth. to put. 10 Another purpose of the invention is to create warp and / or fibers of different colors and / or different fiber blends. Jacquard velvet, with its rich variety of products thanks to the regular or irregular arrangements of the weft yarns. The goal is to enable the production of fabric.

Detailed Description of the Invention This detailed description applies to cellulose-based fibers, primarily cotton, and / or fibers derived from these fibers. composed of a mixture, with warp yarn dyed with indigo dye and additional weft yarn, and It relates to the production method of jacquard weft velvet and denim fabrics woven with different patterns, Example 5, to facilitate a better understanding of the subject, without creating any limiting effects. This is explained through applications. Dyeing of warp yarns with indigo and / or sulfur dyes in the denim industry. It is made as continuous open-width (Slasher) or rope. The open-width continuous threads... To be dyed, the yarns are wound from bobbins onto spools, and then continuously... They are dyed and sized, making them ready for weaving. The yarns are then processed into ropes of 10... To be dyed, the threads are transferred from bobbins to form ropes, which are then dyed. The rope is unwound, wound onto the beam, sized, and made ready for weaving. If continuously dyed yarns are to be used as weft yarns, The dyed yarns are wound onto small beams and then formed into bobbins. This This method is Bossa's registered patent number 2012 04669. This method is suitable for denim fabric 15 warp yarn used in its production and continuously dyed with indigo dyes Besides being used as weft yarn in weaving, it is also used in knitted fabric production and in various other fields. It enables its use. The invention relates to a denim product group, consisting of cellulose fibers, woven in jacquard with additional weft yarns, and After weaving, all or part of the additional weft threads are cut to create weft velvet fabric 20 By ensuring its formation, denim fabrics with different patterns and effects can be produced. to provide. In Figure -1, consisting of warp yarns (10), weft yarns (20) and additional weft yarns (30), It shows a jacquard fabric with a rectangular pattern (60) and a dominant pattern on the surface (50). Figure 2 shows the additional weft yarns cut in addition to those in Figure 1, and their dry and / or wet post-treatment. 25 the velvet wicks formed as a result (70) and the ground connection seen between two velvet wicks (80) It is seen. The width of corduroy (70) is the warp yarn (10) over which the additional weft yarn (30) jumps. It varies according to the number and quantity. The distance between the two wicks (80) is also the warp yarn. According to the thickness and the ground connection weave report of the weft yarn (20) with the warp yarn, 30 It varies. 6 This production method is widely used in denim fabric, corduroy fabric, and jacquard weaves. It will lead to wealth. In Jacquard weaving, each warp thread can move independently. The number of warp threads that the additional weft threads skip over, the width and length of the fabric. It may vary. Thus, the width and length of the fabric may differ in weft velvet fabric 5 It can be produced. However, velvet fabric with different widths and lengths can also be produced. We can see fabrics with different patterns, but none of which are velvet, together. It is obtained by dyeing with indigo dye and by post-processing after garment manufacturing. By producing fabrics woven on jacquard looms in patterns that closely resemble the desired effect and visuals. In conventional denim product manufacturing, chemicals, energy, and 10% of the post-garment waste is used. As the need for manual labor is eliminated, the effects and visuals in the designs will last longer. will be. The warp yarn, weft yarn, and additional weft yarn will create a velvety weft in places, and in other places it will be different. some of the additional weft threads of jacquard fabric woven to form patterns or All of them are cut on cord cutting machines and then subjected to different dyeing and / or finishing. 15 treated with one or more of the following processes (burning, brushing, washing, desizing, top dressing) (painting, etc.) are processed into finished products. The weave pattern of the jacquard fabric, which has areas of weft velvet, includes yarn counts and additional weft yarns. the number of warp threads skipped, the cutting of regular or irregular additional weft threads, Data such as frequency are relevant for determining the pile height and appearance of plain or patterned denim velvet fabric. These are important parameters. Different patterns, different widths of weft velvet, and their regularity on the surface. In addition to being irregular, denim velvet can also be enhanced by adding patterns in printing to this variety. and / or the variety of velvet with denim patterns will increase. With our invention, in addition to the production of jacquard denim velvet fabric, we can also produce jacquard non-denim weft velvet. Fabric production will also be involved. The weft yarn, warp yarn, and additional weft yarn will be one or 25 It consists of more than one natural and / or synthetic fiber, these fibers or compositions made from these fibers. Whether the yarns are dyed or undyed, up to the post-weaving or garment stage There is a great deal of variety in denim and non-denim products through the dyeing of fabric at any stage. wealth will be generated.
