3-YARN CIRCULAR KNITTED FABRIC AND THE PRODUCTION METHOD THEREOF

Description

The Related Art

[0001] The invention relates to knitted fabrics in the field of textiles. The invention particularly relates to a 3-yarn circular knitted fabric obtained by feeding of cotton yarn and water soluble yarn together as the rear yarn and the production method thereof.

The Prior Art

[0002] Knitted fabrics are flexible, elastic, firm and soft textile surfaces which are formed by making yarns into loops by means of needles.

[0003] Knitted fabrics are classified as single-plate knitted fabrics and double-plate knitted fabrics. Single-plate knitted fabrics consist of single jersey, two yarn, three yarn, towel, and pique fabrics. Double-plate knitted fabrics consist of rib, interlock, royal rib, and camisole fabrics.

[0004] These are relatively thick knitted fabrics, with front and rear sides differing from each other, having a front side with a single jersey appearance, and a rear side with usually thick and skip yarns. It is usually used for making sweat t-shirts, hooded cloaks, and upper and lower sweatpants in raised and non-raised form.

[0005] Two yarn knits are formed in four systems using two different numbers of yarns. Over the weaver's shuttle, first of all, the yarn to be seen on the fabric is passed, and then, from the rear hole, the yarn mostly seen from the rear surface is passed. The yarn that will be visible on the rear surface is the yarn that has the thicker number.

[0006] Two-yarn fabrics are produced in circular knitting machines equipped with one-plate platinum. The lining yarns are placed on the rear surface after having a strap form. In the first line, the yarns seen on the front surface are knitted with all needles. In the second line, these lining yarns take the form of lining by skipping three needles with the effect of the platinums. These lining yarns are not visible on the front surface, and normal loops are present. Meanwhile, on the rear surface, completely lining yarns are dominant. The stretching of the fabric across its length is rather limited. This characteristic is due to the strength provided to the knitting by the lining yarns. The fabric has a firm feel.

[0007] Three yarns are used in making of three-yarn fabric. Three-yarn knitting is a knitting type obtained by knitting three yarns separately (ground, lining and connecting yarn) so that a reverse surface will be obtained which would form a more solid structure. It is heavier and has higher basis weight than two-yarn. The most important characteristic of these fabrics is that the thick yarn is less visible on the surface and the surface appearance quality is provided in fabrics having two different coloured surfaces.

[0008] Three-yarn knitted fabrics are obtained in single-plate circular knitting machines. The difference of the three-yarn knitting machines from the single jersey machines is that the structure and arrangement of the shuttle, platinum, needles, and locks are special for the three yarns. Three-yarn knitting is a kind of knitting obtained by preparing platinum arrangements in different ways and feeding yarn from three different channels. One of the two yarns used in the knitting with the same number is the ground and the other is the connecting yarn. The third yarn is the pile yarn that is thicker than the connecting yarn and appears as a skipping in the reverse direction of the fabric. The fabric front surface has regular R-loop bars. On the rear surface, there is a net-like structure. This net-like appearance originates from the skipping of the lining yarn. This fabric has good transverse stability. Its elasticity is extremely limited.

[0009] Different from two-yarn knitted fabrics, three-yarn knitted fabrics are produced by incorporating a third yarn (connecting yarn) in addition to the ground and lining yarns. Generally, with the three yarns used differently from each other, the ground knitting is formed by the first ground yarn, the surface is formed by the second yarn (lining yarn) and the structure is strengthened by the third connecting yarn, and the lining yarn is prevented from appearing on the front surface of the fabric. These fabrics are heavier knitted fabrics.

[0010] In circular knitting machines, the needles are arranged next to each other and in the needle channels laid on circular needle beds to increase production speed. Generally, the yarn is fixed, and the needles are moving. The knitting occurs in a circular plane and forms a fabric tube. Fixed cams are placed around the cylinder and knitting is performed by means of rotating the cylinder on which the needles are placed. The knitted fabric is pulled down through the cylinder of the machine. The yarns are fed to the systems from above. Circular knitting machines work faster than tricot (flat knitting) machines.

[0011] Nowadays, 3-yarn circular knitted fabrics are manufactured by various companies. However, in the yarns used in the front and middle parts of said knitted fabric, a work has been carried out to improve the touch or increase the comfort of the user.

[0012] 3 yarn fabrics are heavy fabrics due to their structure. Therefore, the use of these heavy basis weight fabrics becomes quite difficult, if the surface formed by the rear yarn which touches the skin of the user is not formed in the desired softness. Works such as softening the rear yarn or using low twisted yarns in the contact area of the skin had been tried, but the desired softness could not be achieved. As a result, an improvement is required in the relevant technical field.

[0025] The structural and characteristic features of the invention and all of its advantages shall be understood better with the below given detailed description. Therefore, the assessment should be made by taking into account the detailed descriptions.

Detailed Description of the Invention

[0026] In this detailed description, the preferred embodiments of the 3-yarn circular knitted fabric and the production method thereof according to the invention are only disclosed for better understanding of the subject without forming any limiting effect.

[0027] The invention relates to a 3-yarn circular knitted fabric with softness providing extra comfort and the production method thereof. In the production of said yarn;

• front yarn with effect or plain (all yarns made of cellulosic and regenerated fiber types, cotton, tencel-lyocell, modal, viscon, lenpur, all synthetic fibers, pes, nylon 6, nylon6,6 and etc.)
• Middle yarn with effect or plain and S-twist (all yarns made of cellulosic and regenerated fiber types, cotton, tencel-lyocell, modal, viscon, lenpur, all synthetic fibers, pes, nylon 6, nylon6,6 and etc.)
• Rear yarn consisting of cellulosic, synthetic, or regenerated fibers and water soluble yarns (solvron yarn).

[0028] It is possible that the thicknesses of the front, middle, and rear yarns change according to fabric basis weight. The outer surface appearance of the fabric can be changed by optionally using front yarns which have effect or are plain. In this way, 3-yarn circular knitted fabrics having variety of different visuality can be obtained. The middle yarn being S-twisted contributes to the bulking operation at the rear surface of the fabric. The middle yarn twisted differently from the front yarn has the tendency to stay away from the front yarn. Some part of the rear yarn is formed of water soluble yarn.

[0029] The 3-yarn circular knitted fabric production method generally comprises the operation steps of:

• Preparing the front, middle, and rear yarns,
• Feeding of the front and middle yarns consisting of cellulosic, synthetic, or regenerated yarns, together with the rear yarn consisting of cellulosic, synthetic, or regenerated yarns and water soluble yarn, into a circular knitting machine,
• Performing 3 yarn knitting operations in the circular knitting machine,
• Bleaching,
• Tube cutting,
• Beating, and
• Fixing.

[0030] As the rear yarn, preferably, cotton yarn and 80/1 NE solvron yarn (water soluble yarn) are fed into the knitting machine during the knitting operation to form the rear surface of the fabric. After fabric knitting operation is performed in the circular knitting machine, bleaching operation is made at 130 °C for 4 minutes. With this operation, solvron yarn is melted. Following bleaching operation, beating is applied onto the fabric at 135 °C at a speed of 9 m/min. The piles are opened at 15 strikes. In the beating machine, 40 g/m² softener is given to the dry fabric. It is fixed by passing through ram at 80-110 °C. During fixing operation, the inlet mould would be 1100 mm, while the outlet mould is 1750 mm.

[0031] After the fabric is knitted, solvron yarn is melted and the cotton yarn forming the rear yarn is bulked even more with beating operation. In this way, softness providing extra comfort in 3-yarn circular knitted fabric is achieved.

[0032] The use of the 3-yarn circular knitted fabric according to the invention in all kinds of outerwear is possible. With the extra softness characteristic, it would please the user as man, woman, and especially kids wear material, especially where comfort and softness are of importance.

[0033] In the production method according to the invention, solvron yarn is combined with cotton yarn and used at the rear part of the fabric. Solvron yarn is melted with washing operations. The spaces left by the molten solvron yarn gives a loose style to the rear side of the fabric.
