<Industrial Application Field> The present invention relates to a multilayered spun yarn suitable as a material for clothing that is comfortable to wear against sweat, particularly as a material for sports clothing. <Relationship with conventional technology> Conventionally, natural fibers have been used as materials for sports clothing.
100% yarn, blended yarn of natural fiber and polyester fiber, and spun yarn of 100% polyester fiber have been widely used. By the way, there are various properties required for materials for sports clothing, and among these properties, the properties required such as wash resistance, abrasion strength, heat retention, and elasticity vary depending on the sport, but sweat resistance (Including insensible excretion and sweating during exercise and in hot environments; hereinafter used interchangeably) is a commonly required characteristic value. Comfort against sweat is determined by the stuffiness and stickiness of clothing, which are important elements in clothing design, and are also greatly influenced by the properties of the fabric that makes up the clothing. However, at present, the materials used are not determined from the viewpoint of comfort against sweat, but from the viewpoint of appearance, such as texture and color development, and durability, such as wear resistance. The above-mentioned materials for sports clothing that have been conventionally used are no exception; for example, the single yarn denier of the commonly used cotton/polyester blended polyester fiber is 1.2 to 2.5 denier. is used. For this reason, the capillary action between the fibers could not be exerted significantly, and sweat was not absorbed, making the garment uncomfortable to wear, which in turn caused health problems. In addition, in the case of yarn made from 100% natural fibers or hydrophobic fibers,
In the former case, it has the effect of absorbing water and moisture, but does not have the function of releasing moisture, and in the case of the latter, it does not have the effect of absorbing water and moisture, and both lack the comfort against sweat as a sports material. <Purpose of the Invention> The present invention was achieved based on the knowledge that in order to make clothes comfortable to wear, the structure of the yarn itself has a large influence in addition to the structure of the fabric. An object of the present invention is to provide a multilayered spun yarn suitable as a material for clothing with good properties, particularly as a material for sports clothing. <Configuration of the Invention> The present invention has the following configuration to achieve the above object. That is, in the present invention, staple fibers made of hydrophobic fibers having a fineness of 1.0 denier or less are arranged in the innermost layer, staple fibers made of hydrophilic fibers are arranged in the outermost layer, and between the innermost layer and the outermost layer. The multilayer spun yarn is characterized in that it is a spun yarn in which at least an intermediate layer consisting of staple fibers of hydrophobic fibers of more than 1.0 denier and 1.5 denier or less is present. The present invention will be explained in detail below. In the present invention, the multilayer spun yarn includes an innermost layer, an outermost layer, and at least one intermediate layer between the innermost layer and the outermost layer. This is to allow sweat to transfer smoothly. First, the staple fibers placed in the innermost layer are
The hydrophobic fiber must have a fineness of 1.0 denier or less, preferably less than 1.0 denier, and more preferably 0.1 to 0.8 denier. This utilizes the capillary action of the fine denier hydrophobic fibers in the innermost layer to transfer liquid sweat through the outermost skin-side layer, the middle layer, and into the innermost layer.
This is because liquid phase sweat absorbs its own heat and evaporates. In order to effectively generate capillary action, fineness must be adjusted.
Must be 1.0 denier or less. If it exceeds 1.0 denier, sweat transfer will be less likely to occur. Also,
Hydrophobic fibers are used because the fibers themselves do not retain sweat, but they retain sweat between the fibers, absorbing the heat of the sweat itself and vaporizing it. Here, hydrophobic fiber means 65%
RH, official moisture content at 20℃ (JIS L-1096)
is less than 5%, and has a difference in official moisture content of 1% or more from the hydrophilic fibers described below. Examples include polyester fibers, acrylic fibers, polyamide fibers, vinyl chloride fibers, and the like. Further, the reason why the fibers are limited to staple fibers is to generate more capillary phenomenon. From this point of view, it is preferable that the average fiber length of the staple fibers is in the range of 20 to 60 mm, and the form of the staple fibers is preferably a cut of equal length rather than a burr cut. The weight% of hydrophobic fibers of 1.0 denier or less is usually 10 to 45% by weight, preferably 30% by weight based on the entire spun yarn.
~45% by weight. This is because if it is less than 10% by weight, capillary action becomes difficult to occur, and if it exceeds 45% by weight, it becomes difficult to absorb sweat. Next, the staple fibers placed in the outermost layer must be hydrophilic fibers. This is because the hydrophilic fibers on the skin side quickly absorb a large amount of sweat (both gaseous and liquid) produced by the human body. In addition, the hydrophilic fibers in the outermost layer on the outside air side absorb the sweat (vapor phase) vaporized in the innermost layer,
This is because the sweat in the gaseous phase released from the human body and the sweat in the gaseous phase vaporized in the innermost layer are dissipated into the outside air using the water vapor pressure difference with the outside air. Here, hydrophilic fiber refers to the official moisture content (JIS L) at 65% RH and 20°C.
-1096) is 5% or more fibers, such as cotton,
These include natural fibers such as hemp and wool, and recycled fibers such as viscose, rayon, and polynosik. The finer the hydrophilic fiber, the better.
It is preferably 10 to 20 deniers, more preferably 1.01 to 1.5 deniers. The reason why the hydrophilic fibers in the outermost layer are limited to staple fibers is to provide a suitable amount of fluff to improve the texture. The amount of hydrophilic fibers is preferably 50 to 80% by weight based on the entire spun yarn. If it is less than 50% by weight, it will be difficult to absorb a large amount of sweat, and if it exceeds 80% by weight, it will be difficult for capillary action to occur. Further, between the innermost layer and the outermost layer there must be at least an intermediate layer made of hydrophobic fibers, preferably hydrophobic synthetic staple fibers, having a denier of more than 1.0 denier and less than 1.5 denier. The intermediate layer serves as a cushion and appropriately suppresses the transfer of liquid phase sweat. The intermediate layer mainly consists of 100% hydrophobic staple fibers having a fineness of more than 1.0 denier and less than 1.5 denier. Here, if the fineness is less than 1.0 denier, it is not preferable because more liquid phase sweat will transfer to the innermost layer than the innermost layer absorbs the heat of sweat and evaporates. On the other hand, if it exceeds 1.5 denier, the degree of utilization of capillary action will be reduced and the transfer of liquid phase sweat from the intermediate layer to the innermost layer will be reduced, which is not preferable. The hydrophobic fibers refer to those already mentioned above. A first boundary layer between the innermost layer and the intermediate layer includes the staple fibers of the innermost layer and the staple fibers of the intermediate layer, and the staple fibers of the intermediate layer and the staple fibers of the intermediate layer exist between the intermediate layer and the outermost layer. There may be a second boundary layer in which the staple fibers of the outermost layer are present. This is because if there is a capillary gradient in the innermost layer, first boundary layer, middle layer, second boundary layer, and outermost layer, liquid phase sweat will migrate to the innermost layer. The first boundary layer and the second boundary layer are usually thin layers.
Furthermore, the proportion of hydrophobic fibers having a diameter of more than 1.0 denier and less than 1.5 denier relative to the entire multilayer spun yarn of the present invention is preferably 5 to 20% by weight.
More preferably, it is 5 to 10% by weight. Barefoot,
This is to allow the capillary phenomenon to occur smoothly.
If it is less than 5% by weight, the role of the cushion is lost, while if it exceeds 20% by weight, capillary action will be impaired. The twist coefficient (inch system) of the multilayered spun yarn of the present invention is preferably 3.0 to 4.0. Next, to briefly describe the mechanism of sweat absorption and wicking in the multilayer spun yarn of the present invention, the hydrophilic fibers in the outermost layer on the skin side quickly absorb a large amount of sweat (both gas phase and liquid phase) from the human body. Due to the capillary action of the fine denier hydrophobic fibers in the innermost layer, liquid sweat passes through the middle layer and moves to the innermost layer, and the liquid sweat in the innermost layer absorbs its own heat and evaporates, turning into a gas phase. Due to the difference in water vapor pressure between the skin side and the outside air side, water gradually passes through the middle layer,
The sweat in the vapor phase is absorbed by the hydrophilic fibers in the outermost layer on the outside air side, and then, due to the difference in water vapor pressure between the skin side and the outside air side, the sweat in the vapor phase passes through the hydrophilic fibers in the outermost layer, moves to the outermost layer on the outside air side, and is further absorbed into the outside air. The hydrophilic fibers in the outermost layer quickly wick away sweat in the vapor phase. <Effects of the Invention> As described above, according to the present invention, a multilayer spun yarn suitable as a material for clothing, particularly a material for sports clothing, can be obtained, and this multilayer spun yarn has a fabric structure and can provide a comfortable material for sports clothing. A good climate can be obtained even when used for thin knitwear that is difficult to wear. Example 0.7 denier x 32 mm (equal length) polyester fiber sliver (70% by weight) and 1.4 denier x 38
Using a sliver (30% by weight) of cationic dyeable polyester fiber (30% by weight) that can be dyed under normal pressure,
A 0.7 denier polyester fiber sliver is placed in the center, and 1.4 denier cationic dyeable polyester fiber slivers are arranged on both sides of the sliver, which is then fed to the cross roller of a drawing machine and given a draft to produce a mixed sliver. Using the mixed sliver (33% by weight) and a separately spun 100% cotton sliver (67% by weight), a roving machine was set so that the mixed sliver was in the core and the 100% cotton sliver was in the sheath. A roving is produced, and then a spinning machine is used to produce a 40/1′S (twist coefficient 3.2) multilayer spun yarn (the weight percentage of the innermost layer, middle layer, and outermost layer is 23.1:
9.9:67) was produced. The physical properties of this multilayered spun yarn were as shown in Table 1 below. For comparison, a blended yarn with a weight percent ratio of 33:67 was produced using 1.4 denier x 38 mm polyester staple fibers and cotton fibers and is also listed in Table 1. These yarns were then used to knit smooth using a 30 inch 26 gauge knitting machine. The knitted fabric
