BACKGROUND OF THE INVENTION

The untwisted yarns are being limited greatly, because the untwisted yarns are used for making the towels in the present field. Varies fabrics, which have been authorized preliminarily in the market, are woven by untwisted yarns, since the applicant developed the untwisted yarns fabric these years. From further research we found: the production of the untwisted yarns needs vinylon, then vinylon should be removed at last, so, the method of producing the untwisted yarns will pollute environment seriously. The cost of solving the kind of the pollution is high, which increases the cost of the fabrics.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide one kind of ply yarns and the ply yarns fabric, the ply yarns are composed by untwisted yarns and twisted yarns. The vinylon needn't stranded to produce the ply yarns when we produce the ply yarns, so that the production processes, the waste and the cost can be reduced, the pollution can be removed. The ply yarns have good softness, hygroscopicity and structure stability. The fabrics, which are woven by the ply yarns, have good crisp aesthetics and softness.

The present invention concerns the ply yarns. Said ply yarn being made by intertwisting one piece of untwisted yarn and one piece of twisted yarn or filament in a direction of the length. The twist factor of the untwisted yarn is below 200, and the fibers of the untwisted yarn are parallel.

In the ply yarns, the untwisted yarns and the twisted yarns are linear, the twisted yarns intertwist the untwisted yarns linearly.

The present invention adopts the ply yarns to make the ply yarns fabric. The fabric contains the warp yarns and the weft yarns which form the noumenon of the fabrics. One piece of the ply yarn is made by intertwisting one piece of untwisted yarn and one piece of twisted yarn or filament in the direction of the length. The twist factor of the untwisted yarn is below 200, and the fibers of the untwisted yarn are parallel, the untwisted yarns are linear, so that the bulgy parts could be formed on the surface of the fabric.

The ply yarns of the fabric have good program for arranging the ply yarns: the ply warp yarns are arranged one by one, and the ply weft yarns are arranged one by one. The ply warp yarns and the ply weft yarns are arranged vertically; the ply warp yarns are arranged one by one, and the ply weft yarns are arranged one by one. The ply warp yarns and the ply weft yarns are arranged slantways.

In the present invention, the density of the ply fabric is between 60 and 800 pieces per 10 cm. One of the optimally selected schemes is: the density of the fabric is between 220 and 500 pieces per 10 cm. Another optimally selected scheme is: the density of the fabric is between 60 and 200 pieces per 10 cm.

The advantages of the present invention: we can produce the ply yarns without the vinylon, that we needn't inertwist the vinylon to form the ply yarns and remove the vinylon. So, the production processes, the waste and the cost can be reduced, the environment pollution can be removed. The ply yarns fabric has high tensile strength, good crisp aesthetics and it maintains softness, air porosity, hygroscopicity, the heat retention and the stronger affinity for our skin as the untwisted yarns fabrics have.

DETAILED DESCRIPTION OF THE INVENTION

In FIG. 1, said ply yarn being made by intertwisting one piece of untwisted yarn 1 and one piece of twisted yarn or filament 2 in a direction of the length. The twist factor of the untwisted yarn 1 is below 200, and the fibers 3 of the untwisted yarn 1 are parallel. The ply yarns have many combined arrangements, for example, the untwisted yarn 1 and the twisted yarn 2 are linear, the untwisted yarn 1 intertwistes the twisted yarn 2 linearly; the untwisted yarn 1 is curvilinear, the twisted yarn 2 is linear, the untwisted yarn 1 intertwistes the twisted yarn 2 in the direction of the length; the circularity is set on the untwisted yarn 1, the circularity is set on the twisted yarn 2, the untwisted yarn 1 intertwistes the twisted yarn 2 in the direction of the length; the circularity is set on the untwisted yarn 1, the twisted yarn 2 is linear, the untwisted yarn 1 intertwistes the twisted yarn 2 in the direction of the length. The twisted yarns as described above also can be replaced by filaments.

The ply yarns fabric, which is described as the present invention, contains the warp yarns 8 and the weft yarns 9. The warp yarns 8 and the weft yarns 9 compose the fabric noumenon. The warp yarns 8 or the weft yarns 9 are the ply yarns which are made by intertwisting the untwisted yarns 6 and the twisted yarns or filaments 7 in the direction of the length. The twist factor of the untwisted yarns 6 is below 200, and the fibers 10 of the untwisted yarn 6 are parallel. So, the bulgy parts could be formed on the surface of the fabric. The bulgy parts can increase the third dimension of the fabric. The hygroscopicity can be increased when the shape of the bulgy part is circularity.

In the present invention, the density of the fabric is between 60 and 800 pieces per 10 cm, with which we will produce the fabrics having good crisp aesthetics. One of the optimally selected schemes is: the density of the fabric is between 220 and 500 pieces per 10 cm; another optimally selected scheme is: the density of the fabric is between 60 and 200 pieces per 10 cm, in this case, the crisp and softness of the fabric will be increased.

In the present invention, the warp yarns 8 and the weft yarns 9 have the following arrangements: the ply warp yarns 8 are arranged one by one, the ply weft yarns 9 are arranged one by one, the ply warp yarns 8 and the ply weft yarns 9 are arranged vertically. This is one of the optimally selected schemes, with which we can accomplish the purpose of the present invention better; another scheme is: the ply warp yarns 8 are arranged one by one, the ply weft yarns 9 are arranged one by one, the ply warp yarns 8 and the ply weft yarns 9 are arranged slantways. This is anther optimally selected scheme, with which we can also accomplish the purpose of the present invention better.

In the present invention, the warp yarns 8 or the weft yarns 9 are the ply yarns, also the warp yarns 8 and the weft yarns 9 are all the ply yarns. For example, the warp yarns 8 and the weft yarns 9 are all the ply yarns which are made by intertwisting the untwisted yarns 6 and the twisted yarns or filaments 7, the twist factor of the untwisted yarns 6 is below 200; in order to decrease fluffs of the fabric and increase the crisp aesthetics, we can use the ply yarns in the warp yarns or the weft yarns. For instance, we can use one piece of the single yarn and the ply yarn to compose the fabric, the single yarn is the warp yarn 8 or the weft yarn 9, the single yarn can be the twisted yarn or filament 7. There are many arrangement schemes: in the fabric, the warp yarn 8 is the twisted yarn 7 (the single yarn), the weft yarn 9 is the ply yarn; in the fabric, the weft yarn 9 is the twisted yarn (the single yarn), the warp yarn 8 is the ply yarn; the warp yarn 8 and the weft yarn 9 are arranged vertically, or the warp yarn 8 and the weft yarn 9 are arranged slantways. Another scheme is: in the fabric, the warp yarn 8 is the untwisted yarn (the single yarn), the weft yarn 9 is the ply yarn; in the fabric, the weft yarn 9 is the untwisted yarn (the single yarn), the warp yarn 8 is the ply yarn; the warp yarn 8 and the weft yarn 9 are arranged vertically, or the warp yarn 8 and the weft yarn 9 are arranged slantways; the warp yarns 8 are arranged by the single yarns and the ply yarns, the weft yarns 9 are arranged by the ply yarns; the weft yarns 9 are arranged by the single yarns and the ply yarns, the warp yarns 8 are arranged by the ply yarns.
