Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a towel. More specifically, the present invention relates to a towel fabric that is made of a two-layer spun yarn with a synthetic fiber staple in the core and cotton fiber in the sheath, and has high strength, energy saving properties, excellent washing resistance, and a flexible texture.

[Prior Art] Conventionally, the majority of towels have been made of 100% cotton, reflecting consumers' strong preference for moisture absorption.

However, 100% cotton towels have the disadvantage that they are not very strong, and their texture changes significantly after washing, making them hard and easily torn.

Especially in rental applications where functionality is sought after, there is a strong desire to develop towels that are durable, quick drying (energy saving in the drying process during washing), and wash resistant.

On the other hand, as a countermeasure to this problem, attempts have been made to use blended yarns of synthetic fibers and natural 3I/miscellaneous yarns.

However, towels using homogeneously blended yarns have the functionality of synthetic II miscellaneous materials, but there is a problem in that the properties of natural fibers are diluted to that extent.

[Problems to be Solved by the Invention] The present invention was devised in view of the various drawbacks of the prior art, and its purpose is to provide a material that is flexible, has water absorption/hygroscopicity, is bulky, and has durability, energy saving, etc. The idea is to offer a towel that also serves as a gift.

[Means for Solving the Problems 1] The object of the present invention is to provide a towel mainly composed of a core and sheath type two-layer spun yarn, in which the sheath part is made of a group of cotton fibers, and the core part is made of a cotton fiber group. This is achieved by a towel made of synthetic fiber staples and characterized in that the sheath portion accounts for 50 to 80% by weight of the entire two-layer spun yarn.

In other words, the towel of the present invention is synthetic! It is important to have a two-layered spun yarn consisting of a core made of IN staples and a sheath made of cotton fibers, or to be composed mainly of the spun yarn, which gives the towel excellent texture and water absorption. sex,
It can provide functionality such as durability, quick-drying properties, and washing resistance as well as hygroscopicity.

The proportion of the cotton fiber group for forming the sheath in the two-layer spun yarn is preferably 50 to ao% by weight, so that the synthetic 11i11 of the core is covered with the fibers of the sheath as much as possible, and the core It is possible to prevent uneven dyeing and changes in appearance that occur due to the appearance of carbon dioxide on the surface in places, and to take advantage of the characteristics of cotton fibers and synthetic fibers. When the proportion of cotton 1Iit4 exceeds 80% by weight, functionality such as durability, drying performance, and washing resistance decreases,
I can't find anything suitable for rental use. If it is less than 50%, it is not preferable because properties necessary for the towel, such as water absorption and hygroscopicity, may deteriorate or uneven dyeing may occur due to poor coverage.

The towels of the present invention may be woven or woven.

That is, in the present invention, if the above-mentioned two-layer spun yarn is used for all the pile yarns, ground warp yarns, weft yarns, etc. that make up the woven towel, a woven towel with high strength, wash resistance, and improved energy-saving effect can be obtained. However, it is desirable to use 100% cotton yarn only for the pile warp, especially for fields that require water absorption, moisture absorption, and wash resistance, such as barber shops.

On the other hand, in the case of woven towels, the above-mentioned two-layer structure yarns can be used for all of the front pile yarns, back pile yarns, chain yarns, and overlock yarns to make knitted towels, and compared to woven towels, the towels do not shed pile easily. You can get things that are difficult.

In the case of knitted towels, they are usually knitted using a double raschel machine, but the knitting efficiency is generally better with filament yarn than with spun yarn, and with a smaller basis weight than with a larger one.
If knitting efficiency is important, only chain yarn can be synthesized! It is better to use lt4 filament.

In addition, filament yarns generally have higher heat shrinkability than spun yarns, and if high shrinkage type filament yarns are used in particular, the fabric weight can be increased during dyeing after knitting, so the fabric weight can be reduced during knitting. Efficiency can be increased.

In addition, since the chain yarns hardly appear on the surface of the knitted fabric, they do not have a major effect on the towel properties, and knitted fabrics generally have better water absorption than woven fabrics, but even so, the proportion of filaments is 10% of the towel weight. It is best to do the following.

In the present invention, the synthetic gA fibers refer to polyester, polyamide, acrylic fibers, etc. Among them, in the case of polyester, the effects of the present invention can be particularly exhibited, and a towel with high commercial value can be produced.

The two-layer spun yarn used in the present invention can be easily obtained, for example, by the method described in Japanese Patent Publication No. 56-11776.

[Example] High shrinkage type polyester staple 1.5dX 38
208 two-layer structured yarn (twist coefficient = 4.1) was made by blending n++n (boiling water shrinkage rate 9%) and cotton card sliver at blending ratios T'C and T''C, respectively. 208 spun yarns made of cotton card sliver (
K=4.1> was made.

Next, we used T”C, T40G two-layer structure yarn and 100% cotton spun yarn, each with a vertical density (ground warp + pile yarn) of 65 yarns/1nch and a horizontal density (horizontal yarn) of 55 yarns/l.

Table 1 shows the tear strength of towels prepared according to the present invention and 100% cotton towels. What is clear from Table 1 (the present invention;
It can be seen that the pruning towel is more than twice as strong in the horizontal direction and 1.3 times as strong in the vertical direction as a 100% cotton towel.

Table 1 Next, a woven towel using T4″C2WJ structural yarn and cotton 1oO
When the washing resistance of 100% cotton towels was compared, as shown in Figure 1, the 100% cotton towels were almost torn after 100 washes and could not withstand further use. A satisfactory towel did not tear even after being washed 150 times, and exhibited burst strength comparable to that of a new 100% cotton towel.

Furthermore, when we compared the dehydration and drying properties of the above three types of samples, as shown in Figures 2 and 3, the towel fabric according to the present invention could significantly shorten both the dehydration time and the drying time compared to the comparative towel fabric. Ta.

In addition, in FIG. 2 and FIG. 3, the water retention rate is determined by the following formula.

However, the towel weight ω after soaking is 1 after soaking the towel in water for 30 seconds, taking it out and hanging it for 15 seconds to drain, and the weight of the towel after drying is 80 After drying for 20 minutes in a tumble dryer at
This refers to what is taken out and measured.

Figure 4 shows the water absorbency of the three types of towel fabric samples mentioned above placed on a sufficiently hydrated cloth. Although the towels that meet the requirements of the present invention are not as good as 100% cotton towels, they are sufficient for practical use. It has water absorbency that can withstand.

In addition, Figures 5 to 7 show the relationship between the number of washings, thickness, compression ratio, and compressive elastic modulus.The towels of the present invention are bulky and flexible both when new and after washing. It is excellent.

Here, the compressibility and compression modulus were determined by the following methods.

Compression rate: Measure 3 (applying a load of J10+f to the towel, its thickness T1), then measure the towel (applying a load of 300C]/a (applying a load of 300C) and measuring its thickness T2), and calculate the opening using the following formula. do.

After measuring (T2) at the compressive modulus of elasticity 2, remove the load,
The thickness T3) is measured and determined by the following formula.

[Effects of the Invention] The present invention is configured as described above, and has excellent texture, bulk, water absorption, and hygroscopicity, as well as durability and
It was possible to obtain a towel with quick drying properties and washing resistance.
