Claims (6)

  1. A towel cloth comprising a ground weave including a warp ground yarn (2a, 2b) and a weft ground yarn (3) crossing each other therein, and a pile yarn (1a, 1b) locked to the ground weave, wherein at least one of the warp ground yarn (2a, 2b), the weft ground yarn (3), and the pile yarn (1a, 1b) is formed of a twisted union finished yarn, and the twisted union finished yarn including a twisted union yarn, characterised in that the twisted union yarn includes two or more rovings twisted in a primary twisting direction as a single yarn, one of the rovings having an even twist, and at least another of the rovings partially having a twist with irregular strand length and twisting angle, the twisted union yarn having undergone fiber opening and being puffy.
  2. The towel cloth according to claim 1, wherein the twisted union finished yarn comprises a cotton and a synthetic fiber with mixing ratios of 40 wt% or more of the cotton and less than 60 wt% of the synthetic fiber.
  3. The towel cloth according to any one of claims 1 to 2, wherein a yarn count of the twisted union finished yarn is 118.1 tex (a count of 5) to 2 tex (a count of 300).
  4. The towel cloth according to any one of claims 1 to 3, wherein a basis weight of the towel cloth is 80 to 1000 g/m 2 .
  5. A method for manufacturing a towel cloth comprising a ground weave including a warp ground yarn (2a, 2b) and a weft ground yarn (3) crossing each other therein, and a pile yarn (1a, 1b) locked to the ground weave, at least one of the warp ground yarn (2a, 2b), the weft ground yarn (3), and the pile yarn (1a, 1b) being formed of a twisted union finished yarn, characterised in that the twisted union finished yarn is manufactured by the steps of: paralleling two or more rovings in the same direction, and primarily twisting the rovings as a single yarn, thereby forming a twisted union yarn; and untwisting the twisted union yarn in the opposite direction to a primary twisting direction within the range of 5 to 80% based on the number of primary twists, and forming a twisted union finished yarn wherein one of the rovings has an even twist, and at least another of the rovings partially has a twist with irregular strand length and twisting angle, the twisted union yarn undergoing fiber opening and being puffy.
  6. The method for manufacturing a towel cloth according to claim 5, wherein the step of forming the twisted union finished yarn includes scratching the twisted union yarn simultaneously with untwisting of the twisted union yarn.

Description

Technical Field The present invention relates to a towel cloth and a manufacturing method thereof. More particularly, it relates to a towel cloth which has a bulky and fluffy texture, is less likely to undergo fluff dropping, and is excellent in water absorbency, and a manufacturing method thereof. Background Art In recent years, with diversified consumer preferences, the texture and high functionality of a towel have been demanded. Out of these, for the texture, there is a high need for a high quality towel which is especially bulky, and has a fluffy feel. In order to allow such a fluffy feel to be exhibited, with a towel woven fabric having a cross sectional structure in which a pile yarn is locked to the ground weave including a warp ground yarn and a weft ground yarn crossing each other therein, there are the method in which the pile length of the pile yarn is increased, thereby enhancing the softness of the pile; and the method in which softening is achieved by using a yarn of a fine count for a pile yarn. However, with either method, although a soft touch can be obtained, the resilience is poor, and a bulky and fluffy texture cannot be obtained. Further, for fluff dropping of a towel, for example, when the towel is washed together with other clothes, or the laundry is folded up, fluffs of the towel are attached. This may cause the experience that the fluffs stand out when the clothes are worn. In contrast, there is the method in which, during manufacturing processing of the towel cloth, the fluffs on the surface of the woven fabric are singed, thereby reducing dropping of fluffs. However, the fluffs of the pile yarn are reduced, resulting in a rough texture of the towel cloth, which is difficult to cope with. Further, the water absorbency is one of the large features of a cotton towel. However, for example, when the moisture is wiped off upon sweating or right after taking a bath, the moisture may not be wiped off sufficiently. The tendency is often observed particularly for the one including a thin towel cloth, and having a less bulky and flat texture. This is due to the fact that the towel is poor in wiping water absorption function performance of quickly absorbing a large amount of moisture attached on the skin, which is the problem to be solved. Against such a problem, there have been proposed various types of twist yarn processing using a ring spun yarn which has gone common mainstream from the technical viewpoint. As the method for imparting the bulkiness, there is the method in which a hard twisted yarn of a cellulose type fiber is starched, and is subjected to a liquid ammonium treatment and a steam treatment; then, to the hard twisted yarn, a water-soluble yarn twisted in the opposite direction to the direction of twisting of the hard twisted yarn is plied; and then, the water-soluble yarn in the hard twisted yarn is dissolved and removed, resulting in a bulky cellulose type fiber (Patent Document 1). Whereas, there are the spun yarn and the woven/knitted fabric of this method (Patent Document 2). Further, there has been proposed processing of a spun yarn in which a single yarn of a spun yarn is starched without using the water-soluble yarn for reduction of costs, and is dried, followed by untwisting in the opposite direction to that of the spun yarn (Patent Document 3). Further, in order to obtain a beautiful stitch style knitted fabric, there has been proposed a high twist tone processed yarn of a synthetic fabric including one single yarn continuously fuse-bonded with the S twist and Z twist alternately twisted along the yarn axis (Patent Document 4). Furthermore, for obtaining a cool contact feeling, a twisted union yarn has been proposed obtained in the following manner: to a single yarn of a spun yarn of a natural fiber or a synthetic fiber, a thermoplastic synthetic fiber multifilament yarn is subjected to false-twist crimp processing in the opposite direction to that of the spun yarn single yarn; then, the false twisted yarn and the spun yarn are combined, and twisting is performed in the same direction as that of the spun yarn single yarn (Patent Document 5). Further, conventionally, in contrast to the ring spun yarn for which a single yarn is formed by twisting one cotton roving as conventionally widely performed, there is a twisted union yarn (Sirospun) for which one roving and another roving are aligned in parallel with each other, and the two yarns are combined and twisted, thereby forming a single yarn. The following is introduced: the twisted union yarn is higher in strength elongation of yarn than the ring spun yarn; for this reason, yarn breakage of a warp is not caused, so that the weavability can be improved (Non-Patent Document 1). However, the technology of plying and dissolving and removing the water-soluble yarn twisted in the opposite direction to the direction of twisting of the hard twisted yarn of Patent Document 1 or Patent Document 2 involves the dissolution remov
