Multinucleus yarn with improved fibre distribution and terry fabric produced from the yarn

Abstract

The present invention provides for a multinucleus yarn manufactured with uniform or substantially uniform distribution of packing density throughout the cross-section of the yarn. The present invention also provides for Terry fabrics (e.g.) towels produced from the manufactured yarn which exhibits enhanced stability of loop structures formed in the towel. Further, the yarn manufactured in accordance with various embodiments of the present invention may also be used for other fabrics for apparels, denims, bed sheets and other end uses as a superior yarn is produced in terms of strength, evenness, hairiness and imperfections.

We claim: 
     
         1 . A process for manufacturing a multinuclueus yarn comprising:
 drawing at least three or more rovings parallelly in a spinning frame such that distance between the extreme right, middle and extreme left rovings is maintained at a first predetermined distance and a separation distance between at least two rovings is maintained at a second predetermined distance;   partially twisting the parallelly drawn three or more rovings such that at least three primary spinning triangles are formed for each of the parallelly drawn three or more rovings, wherein the three primary spinning triangles are disposed within a first predetermined range of angles respectively; and   combining and twisting the partially twisted three or more rovings such that a fourth resultant spinning triangle is formed within a predetermined distance from each of the three primary spinning triangles, the fourth resultant spinning triangle disposed at a second predetermined range of angles,   wherein the twisting of the partially twisted yarn results in a yarn with multiple nucleus formed at three or more zones throughout the cross-section of the resultant yarn.   
     
     
         2 . The process of  claim 1 , wherein the at least three primary spinning triangles are formed with two or more different spinning triangle geometries having at least two different shapes and dimensions. 
     
     
         3 . The process of  claim 1 , wherein the first predetermined distance is less than or equal to 30 mm. 
     
     
         4 . The process of  claim 1 , wherein the second predetermined distance is at least 4 mm. 
     
     
         5 . The process of  claim 1 , wherein the first predetermined range of angles is between 9 degrees and 20 degrees. 
     
     
         6 . The process of  claim 1 , wherein the second predetermined range of angles is between 15 degrees and 44 degrees. 
     
     
         7 . The process of  claim 1 , wherein the fourth resultant spinning triangle is formed within a predetermined distance of 16 mm from vertices of each of the three primary spinning triangles. 
     
     
         8 . A multinucleus yarn comprising multiple distinct nuclei having fibres distributed across the multiple distinct nuclei throughout the cross-section of the yarn, wherein the fibres are recessed within the yarn. 
     
     
         9 . The multinucleous yarn of  claim 8 , wherein the multinucleus yarn has three or more distinct nuclei having fibres distributed across the three or more distinct nuclei throughout the cross-section of the yarn. 
     
     
         10 . The multinucleous yarn of  claim 8 , wherein the multinucleus yarn has uniform packing density throughout the cross-section of the yarn. 
     
     
         11 . A multinucleus yarn formed by the process of  claim 1 . 
     
     
         12 . A terry fabric obtained from a multinucleus yarn manufactured by the process of  claim 1 .
