Description

  The present invention relates to a bath towel using synthetic fibers.

  Bath towels are also said to be body towels, rubs, and scrapes, and there have been many proposals. For example, Patent Document 1 proposes a body towel made of a fabric using monofilament yarns for both warp and weft yarns. Patent Document 2 proposes a body-washing towel using thick yarn spun yarn, synthetic fiber crimp yarn and bulky yarn as the weft yarn. Patent Document 3 proposes a body towel in which a design twist yarn including hemp is woven into a weft yarn. Patent Document 4 proposes a body towel made of a woven fabric using acrylic fibers for warp yarns and pineapple fibers for weft yarns.

  However, a conventional bath towel using a monofilament (Patent Document 1) is liable to damage the skin and can only be used for a short period of time, and has a problem in durability. Further, the bath towel disclosed in Patent Document 2 has a problem that the surface of the towel is smooth and has a problem in cleaning effect, and the spun yarn has a problem that fibers are easily dropped. Also, bath towels (Patent Documents 3 to 4) using natural fibers such as hemp and pineapple fibers are prone to mold and have a hygienic problem.

Japanese Patent No. 4385029 JP 2004-160080 A JP 2002-191527 A JP-A-9-131276

  In order to solve the above-mentioned conventional problems, the present invention provides a bath towel that has a strong woven structure and high durability, has a rough surface on the surface of the towel, has a high cleaning effect, and is less prone to mold.

  The bath towel of the present invention is a bath towel composed of a woven fabric in which the warp yarn and the weft yarn are filament yarns. The warp yarn has a high density portion and a low density portion, and the weft yarn is a synthetic fiber multi-fiber. A yarn including a knitted knitted yarn made of a filament and a real twisted yarn made of a synthetic fiber multifilament, wherein the knitted knitted yarn expresses crimp, and the real stranded yarn has a surface and / Or it protrudes in the state bent in the back surface, It is characterized by the above-mentioned.

  Since the bath towel of the present invention is entirely composed of synthetic fibers, draining is good, it is easy to dry, and mold is not easily generated. Moreover, by using the thread | yarn which has a real twist as a horizontal thread, the textile structure is firm and durability is high. Furthermore, the actual twisted yarn of the weft yarn protrudes in a state where the twisted yarn is bent on the front surface and / or the back surface at the portion where the warp yarn density is low, and the surface of the towel is uneven, and the cleaning effect is high. As a result, it is possible to provide a bath towel that has a firm fabric structure and high durability, and has an uneven surface, a high cleaning effect, and is less prone to mold.

FIG. 1 is a plan view of a bath towel of Example 1 according to the present invention. FIG. 2 is a sectional view of the same. FIG. 3 is a plan view of a bath towel according to the second embodiment of the present invention. FIG. 4 is a plan view of a bath towel of Example 3 according to the present invention. FIG. 5 is a cross-sectional explanatory view of a loom according to an embodiment of the present invention. FIG. 6 is an explanatory view of a main part for driving the weft yarn into the warp yarn.

  The bath towel of the present invention is composed of a woven fabric of warp and weft filament yarns. The fabric structure may be any structure such as a plain structure or a twill structure. The warp yarn may be monofilament or multifilament, but it is preferable to use a monofilament. Warp yarn is provided with a high density part and a low density part. The warp yarn does not have to exist in the low density portion. Specifically, a portion for inserting the warp yarn into the weave of the loom and a space portion where the warp yarn is pulled out and not inserted into the reed (osm) are provided, and the warp yarn is inserted into a normal woven fabric. The portion to be made is a high density portion, and the space portion is a low density portion.

  At least the knitted knitted yarn A and the actual twisted yarn B are used for the weft yarn. The knitted knitted yarn A is obtained by knitting, heat setting, and knitting. Preferably, it is substantially untwisted. Here, “substantially untwisted” does not include positive twisting, but includes twisting during winding and unwinding of the yarn. Of course, it may be completely untwisted. The ratio of the knitted knitted yarn A and the actual twisted yarn B is preferably 1/9 to 9/1, more preferably 3/7 to 7/3 in terms of weight ratio. The knitted knitted yarn A expresses crimps uniformly throughout. On the other hand, the actual twisted yarn B protrudes in a state where the twisted yarn is bent on the front surface and / or the back surface at a portion (space portion) where the warp yarn density is low.

As for the number of twists of the actual twisted yarn B, the twist coefficient K represented by the following mathematical formula is preferably in the range of 1000 to 15000.
K = T × √D
However, T is the number of twists per meter, and D is the fineness: deci tex (weight per 10000 m length: g).

  When the twist coefficient K is in the above range, the bent state of the actual twisted yarn B becomes a loop pile shape. The twist coefficient K is a sweet twist, but when the bath towel of the present invention is woven and then heat-treated and contracted to a predetermined width, there is no warp yarn in the portion where the warp yarn density is low (space portion). The bent state of the actual twisted yarn B becomes a loop pile shape. Thereby, an uneven part is formed on the surface of the towel, and the cleaning effect is enhanced. The actual twist can be added using a twisting machine such as a double twister, an Italian twister, a single balloon twister, a multiple balloon twister, or a ring twister.

  The synthetic multifilament yarn having real twist is preferably continuous crimped fiber (BCF) nylon. BCF nylon is generally used for carpet pile yarns and the like, and is a material that is durable and hard to loosen.

  It is preferable that the part (flat part) with high warp yarn density of the bath towel of the present invention is 0.2 to 20 mm, and the part with low warp density (uneven portion) is 1 to 5 mm. The part with high warp yarn density can be controlled widely because the fabric is made by vertically moving two warp yarns and inserting a weft thread between them in the same way as for normal fabrics. Since this portion is pulled out, this portion does not become a woven fabric and the strength is weakened, so the range that can be formed is limited.

  Next, a method for producing the bath towel of the present invention will be described. Prepare a large number of warp yarns in one direction with a warping machine, and wind them around a warping beam. As shown in FIG. 5, the warp yarns 12 fed from the warp yarn body 14 wound around the warp beam are passed through the wire healds 15a and 15b for opening one by one, and then passed through the barb 16. The weft yarn 13 is driven into a space (also referred to as a front part of the heel) formed between the heel 16 and the final end 18a of the fabric 18, and the heel 16 is pressed against the final end 18a of the woven fabric to form the woven fabric. The formed woven fabric 18 is taken up by a take-up roller to become a fabric 19.

  An example of the relationship between the warp yarn and the weft yarn is shown in FIG. The same reference numerals as those in FIG. A total of six warp yarns 12, three of which are upper yarns of the opening and three of which are lower yarns, are inserted into the stitches 17 of the heel 16. While the six warp threads 12 are inserted, the third eye is kept in a space. A portion where a total of six warp yarns 12 are inserted is a portion having a high warp yarn density, and a space portion is a portion having a low warp yarn density (a space portion). In this way, the high yarn density portion and the low warp portion (space portion) are regarded as one unit, and a large number of units are repeatedly threaded.

  As a means for driving the weft yarn 13, a water jet type, an air jet type, a gripper type, a rapier type, a shuttle type, etc. can be used. The arrangement and order of the knitted knitted yarn and the actual twisted yarn can also be arbitrary. When the weft yarn 13 is driven, if it is entangled with the warp yarn at the end, fraying of the end is prevented. The woven fabric 18 woven in this way has a pattern in which a portion 20a having a high warp density and a portion (space portion) 20b having a low warp density are repeated.

  The woven fabric 18 woven in this way is dyed, heat set, and contracted to a predetermined width. For example, the weaving width is 50 cm and the finishing width is 30 cm. At this time, the real twist yarn protrudes in a bent state on the front surface and / or back surface of the woven fabric at a portion (space portion) where the warp yarn density is low. The knitted knitted yarn develops crimps uniformly throughout. Dyeing may be performed by a conventional method, for example, dyeing with hot water at 80 to 100 ° C. for 1 to 5 hours. The heat setting is preferably a heat treatment condition of 1 to 10 minutes at a temperature not lower than the glass transition point and not higher than the softening point of the polymer constituting the knitted knitted yarn.

  Next, the woven fabric is cut into a predetermined length (for example, 1 m). At this time, if necessary, the cut portion is frayed and the cut portion is sewn to form a bath towel product.

  Hereinafter, the present invention will be described more specifically with reference to examples. In addition, this invention is not limited to the following Example.
