Definitions

• the invention relates to yarns and fabrics used in the field of textile. More specifically, the invention relates to circular knitted fabric wherein the characteristics of flexibility and recovery wanted (the ability to return to its previous position after applying force to the fabric), and to yarns comprising core composed of filament yarn or yarns made of regenerated or synthetic materials with elastane yarn or yarns which are used for obtaining the said circular knitted fabric.
• elastane yarn has started to be used in circular knitting machines intensely. Especially it is common to use elastane yarn in fine circular knitting machines. These are single jersey, rib, interlock, ringel, electronic jacquard, mini jacquard circular knitting machines. Elastane yarn can be used both alone with ground yarn simply and as coated yarn in circular knitting machines.
• EP2762620B1 relates to "Stretch knitted fabrics and clothes".
• the invention comprises a stretch knitted fabric which shows a sudden temperature increase when stretched and has 1.0° or more temperature increase caused by the heat generation in 100% warp direction and/or stretching direction, and composed of an elastic yarn and inelastic yarn.
• TR 2015 16867 relates to "Method for producing elastic shirt fabric comprising spandex and hard yarn”.
• This invention comprises core composite elastic yarn and the method for producing stretch-woven shirt fabrics from this fabric.
• the present invention relates to a flexible and recovering fabric and a yarn used to produce this fabric which fulfils the abovementioned requirements, removes all the disadvantages and brings along some additional advantages.
• Primary objective of the invention is to provide the ability to recovery after applying force to the fabric, at the level desired by users in elastane fabrics.
• the invention aims to prevent appearance defects caused by loosening in stretch fabrics.
• An objective of the invention is to increase the usage performance of circular knitted fabrics containing elastane by use of plurality of core yarns.
• the invention also aims to enable to use core-containing yarns comprising filament yarn or yarns made of regenerated or synthetic materials, with elastane yarn or yarns in circular knitted fabrics.
• Another objective of the invention is to increase the lifetime of circular knitted fabrics including elastane.
• Another objective of the invention is to obtain ready wear product made of circular knitted fabric, which grips the body and does not get deformed after the grip.
• the invention is a yarn made of natural fiber, regenerated fiber, synthetic fiber or a combination thereof, comprising at least one filament yarn made of regenerated or synthetic materials and at least one elastane yarn in its core.
• the said yarn is obtained by feeding at least one filament yarn made of regenerated or synthetic materials with at least one elastane yarn together to the core part during the spinning process after the fibers made of natural fiber, regenerated fiber, synthetic fiber or a combination thereof is corded.
• the invention comprises a fabric obtained from a yarn including a core comprising at least one filament yarn made of regenerated or synthetic materials and at least one elastane yarn.
• the said fabric is a circular knitted fabric.
• the invention comprises a core yarn including filament yarn or yarns made of regenerated or synthetic materials and elastane yarn or yarns in its core and a circular knitted fabric produced by use of this yarn.
• filament yarns that are obtained by chemical methods or from natural materials. For example, while some filament yarn materials are produced from petrol derivative chemicals, some filament yarn materials are of cellulosic origin. In filament yarns, it is common to use nylon and polyester in particular. However, yarns such as pbt, viscose, floss may be preferred.
• the filament yarn type to be chosen depends on factors such as the cost of the final product, desired recovery value based on the usage field and user preferences.
• Method for producing core yarn which is the subject of the invention generally includes the steps of;
• the core yarn which is the subject of the invention is obtained by feeding of the filament yarn or yarns made of regenerated or synthetic materials and elastane yarn or yarns constituting the core part to the yarn core during the spinning process, after making a cord of a fibers made of natural fiber (like cotton), regenerated fiber, synthetic fiber or a combination thereof. Filament yarn or yarns made of regenerated or synthetic materials and elastane yarn or yarns are fed to the yarn core at the same time together.
• elastic core yarn is obtained by feeding only elastane to the yarn core. However, these yarns do not have sufficient elasticity and recovery properties.
• the fabric which is the subject of the invention is a type of fabric obtained by making knitted fabrics in circular knitting machines from the yarns obtained by feeding at least one filament yarn made of regenerated or synthetic materials and a least one elastane yarn to the yarn core during the spinning process of fibers made of natural fiber (like cotton), regenerated fiber, synthetic fiber or a combination thereof.
• Being knitted in knitting constructions designed appropriately for ready wear usage all circular knitting types like rib, interlock, single jersey
• desired circular knitting settings desired diameter, fine, needle frequency and plate settings
• the basis weight, elasticity and recovery properties that the inventive fabric has to have primarily are determined.
• the season in which the fabric is used, field of use and the ready-wear type to be designed are the factors determining the basis weight of the fabric.
• the final yarn number (Ne value) is determined to be used in obtaining the fabric according to the desired fabric basis weight. For example, while the basis weight of a fabric with 40/1 NE of final yarn is measured as 200 gr/m2, the basis weight of a fabric with 20/1 NE of final yarn is measured as 300 gr/m2.
• filament yarn type poly(polyester, nylon, floss, viscose etc.)
• the thickness of the filament yarn to be used and the number to be used in the core are determined.
• the flexibility (elasticity) value chosen according to the field of use the type of the elastane, its thickness and the number to be used in the core (depending on the desired recovery value, 1,2 or more elastane yarns are used) are determined.
• the number of the yarn to be used in the fabric production, types, thicknesses and usage numbers of filament yarn and elastane yarn to be used in said yarn core are determined, core yarn to be used in fabric production is produced.
• the yarns produced are made fabric in the fabric width, fabric basis weight and machine plate settings in accordance with the desired basis weight and construction desired in the circular knitting construction (interlock, rib, single jersey) properly for use in ready-wear and dyeing operations are carried out.
• the inventive core yarn is used in circular knitted fabrics in which the properties of elasticity and recovery after applying force to the fabric wanted.
• the inventive fabric which grips the body by its elasticity and returns its form before wearing by recovering from where it stretches may be used in every part of bottom clothing, top clothing, innerwear and outwear; in male, female, children's wear and in some home textile products.
• the inventive core yarn is fed to the circular knitting machine, knitting process is performed and circular knitted fabrics are obtained.
• the inventive core yarn is obtained by applying blending, fluffing, combing, traction, cording and spinning processes respectively to the fibers comprising natural fiber, regenerated fiber, synthetic fiber or a combination thereof; and feeding the filament yarn or yarns made of regenerated or synthetic materials and elastane yarn or yarns into the yarn core during spinning process.
