A yarn is a fabric woven thinly (with large gaps between yarns). Since the yarn is a thin woven planar fabric, the thickness is thin even with multiple layers of yarn. Thus, the yarn lacks elasticity and softness. In particular, for a textile of yarn made from twisted yarn, elasticity and softness are lacking. The yarn lacks insulative properties because of the less dense weave.

Detailed Description

The following describes embodiments of the present invention. The first aspect of the invention is a scrim. The yarn fabric comprises surface layer yarns, middle layer yarns and back layer yarns. The surface layer yarn is composed of a twisted yarn. At least one of the intermediate layer yarns is formed of a twisted yarn. The back layer yarn is made of twisted yarn.

The surface layer yarn is composed of a twisted yarn having a twist multiplier of 3.3 or less. At least one of the intermediate layer yarns is composed of a twisted yarn having a twist multiplier of 3.5 or more. The back layer yarn is composed of a twisted yarn having a twist factor of 3.3 or less.

The above-described yarn fabrics are used in various fields. When the sewing machine is used in the field of sewing, the characteristics of the sewing machine can be exerted. For example, as a raw material for clothes (evening dress, pajamas, shirts, etc.). However, it is not limited to clothes. For example, it is used as a raw material for various products for infants. For example, it is used as a raw material for bed products.

The yarn fabric is an N-layer fabric (N is an integer of 3 or more). From the viewpoint of weight and cost, N is preferably 3, 4, 5. More preferably N is 3 (three-layer fabric). In the case of a three-layer fabric, the middle layer yarn has one layer.

The yarn fabric comprises surface layer yarns, back layer yarns and intermediate layer yarns. The intermediate layer yarn has, for example, 1 to 3 layers. In particular, it is preferable to have one layer.

The surface layer yarn is composed of a twisted yarn. The surface layer yarn is composed of a twisted yarn having a twist multiplier of 3.3 or less. The back layer yarn is made of twisted yarn. The back layer yarn is composed of a twisted yarn having a twist factor of 3.3 or less. A twisted yarn having a twist multiplier of 3.3 or less is not a non-twisted yarn. 0 < the twist coefficient of the twisted yarn of the surface layer yarn (back layer yarn) is less than or equal to 3.3. The twist multiplier is preferably 3.0 or less. The twist multiplier is preferably 0.3 or more. The twist multiplier is more preferably 0.5 or more. The twist multiplier is more preferably 1.0 or more. At least one of the intermediate layer yarns is composed of a twisted yarn having a twist multiplier of 3.5 or more. At least one of the intermediate layer yarns is preferably formed of a twisted yarn having a twist multiplier of 3.8 or more. In particular, the yarn is composed of a twisted yarn having a twist multiplier of 4.0 or more. The upper limit value is not particularly limited. Yarns without the above-mentioned features may also be used without prejudice to the characteristics of the invention. The twist of the yarn varies depending on the count. The strength of the yarn twist is not represented by the twist number but by the twist factor. For example, the value obtained by multiplying the square root of the count by the twist number is the twist factor per inch. The yarn having a twist multiplier of 3.5 to 5.0 is generally called a medium twist yarn. The yarn having a twist multiplier of 5.0 to 8.0 is generally called a hard twist yarn. A yarn having a twist multiplier of 8.0 or more is generally called an extremely strong twisted yarn.

The face layer yarns and the back layer yarns are bonded together directly and/or indirectly. For example, the surface layer yarn and the back layer yarn are directly bonded by a yarn. Alternatively, the surface layer yarn and the intermediate layer yarn are directly bonded to each other by a yarn (particularly, a twisted yarn constituting the intermediate layer yarn), and the back surface layer yarn and the intermediate layer yarn are directly bonded to each other by a yarn (particularly, a twisted yarn constituting the intermediate layer yarn). As a result, the surface layer yarn and the back layer yarn are indirectly bonded to each other through the intermediate layer yarn.

The twisted yarn having a twist multiplier of 3.5 or more is preferably formed by twisting two or more yarns. The twisted yarn is more preferably a double-ply yarn. The twisted yarn is preferably a yarn having a count of 25 to 80 (more preferably a count of 40 to 70). When the twisted yarn is a two-ply yarn, the twisted yarn is composed of a yarn having a count of 50 to 160 (preferably 80 to 140) and a yarn having a count of 50 to 160 (preferably 80 to 140).

The yarn woven fabric of the above embodiment has a soft hand. That is, since the surface layer yarn (back layer yarn) is made of a twisted yarn having a twist multiplier of 3.3 or less, the hand feeling is soft.

The yarn knitted fabric of the above embodiment has a surface layer yarn (back layer yarn) made of a twisted yarn having a twist multiplier of 3.3 or less, and an intermediate layer yarn made of a twisted yarn having a twist multiplier of 3.5 or more. Therefore, the stereoscopic impression is strong. This is because the shrinkage rate of the surface layer (back layer) yarn is different from that of the intermediate layer yarn. The thickness of the material is increased by the synergistic effect of the unevenness (three-dimensional property) caused by the difference in shrinkage rate and the expansion of the yarn caused by the small twist or the untwisting. As a result, the heat retaining property is excellent. Although thick, it is lightweight.

In the yarn woven fabric of the above embodiment, the twisted yarns are used for the surface layer yarn, the back layer yarn, and the intermediate layer yarn, and therefore, the strength is high. And the sewing property is good.

A second aspect of the invention is a garment (evening dress, pajamas, shirts, etc.) or bedding article (e.g. sheets, blankets, etc.). The product is made of the yarn fabric.

The following examples illustrate more specific embodiments. However, the present invention is not limited to the following embodiments. Various modifications and application examples are also included in the present invention without significantly impairing the characteristics of the present invention.

Fig. 1 is a sectional view of a gauze fabric (triple layer fabric) according to a first embodiment of the present invention.

Reference numerals 1, 2 denote yarns G constituting the first layer (surface layer: upper layer)₁Warp yarns (longitudinal yarns). Reference numeral A, B is a yarn G constituting the first layer₁Weft yarns (cross yarns). The warp yarns 1 and 2 and the weft yarn A, B are twisted yarns. First layer yarn G₁Consisting only of twisted yarns. The twist multiplier of the twisted yarn was 3.0.

Reference numerals 3, 4 denote yarns G constituting the second layer (intermediate layer)₂The warp yarn of (1). Reference numeral C, D is a yarn G constituting the second layer₂The weft yarn of (1). The warp yarns 3 and 4 and the weft yarn C, D are twisted yarns. Second layer yarn G₂Consisting only of twisted yarns. The twist multiplier of the twisted yarn was 4.0. The twisted yarn is a double-ply yarn formed using two yarns having a count of 120.

Reference numerals 5 and 6 denote yarns G constituting the third layer (back layer: lower layer)₃The warp yarn of (1). Reference numeral E, F denotes a yarn G constituting the third layer₃The weft yarn of (1). The warp yarns 5 and 6 and the weft yarn E, F are twisted yarns. Third layer yarn G₃Consisting only of twisted yarns. The twist multiplier of the twisted yarn was 3.0.

In the above yarn G₁、G₂、G₃In the laminated three-layer yarn woven fabric, the warp yarn 3 (or the warp yarn 4) and the weft yarn B (or the weft yarn a) are interwoven at an appropriate position (place) (see fig. 1). I.e. through the intermediate layer yarn G₂The yarn (warp yarn) 3 is twisted to form the yarn G of the second layer₂And the aboveYarn G of the first layer₁Are connected together.

In the above yarn G₁、G₂、G₃In the laminated three-layer yarn woven fabric, the warp yarn 4 (or the warp yarn 3) and the weft yarn F (or the weft yarn E) are interwoven at an appropriate position (place) (see fig. 1). I.e. through the intermediate layer yarn G₂The twisted yarn (warp yarn) 4, the yarn G of the second layer₂With yarn G of the third layer₃Are connected together.

The yarns of the present embodiment are combined by warp yarns (weft yarns).

Yarn G of the first layer₁The yarn G of the second layer₂And yarn G of the third layer₃The yarn may be produced by the same weaving method as that of the conventional three-layer yarn woven fabric, but is not limited thereto.

In a conventional N-layer (N is an integer of 2 or more) woven fabric, the warp yarns of each layer are all the same. In contrast, in the woven fabric of N-layer (N is an integer of 3 or more) yarns of the present invention, twisted yarns having a twist multiplier of 3.3 or less are used as the yarns of the first layer (front layer) and the N-th layer (back layer), and twisted yarns having a twist multiplier of 3.5 or more are used as the yarns of at least one layer of the intermediate layer. Therefore, when producing the N-layer (N is an integer of 3 or more) yarn web of the present invention, a device capable of supplying at least two kinds of yarns is used.

A three-layer woven yarn (comparative example 1) was produced in which the warp yarns 1, 2, 3, 4, 5, and 6 and the weft yarn A, B, C, D, E, F were twisted yarns (twist multiplier: 3.0).

A three-layer woven yarn (comparative example 2) was produced in which the warp yarns 1, 2, 3, 4, 5, and 6 and the weft yarn A, B, C, D, E, F were twisted yarns (twist multiplier 4.0).

A three-layer woven yarn was produced in which the warp yarns 1, 2, 5, and 6 and the weft yarn A, B, E, F were twisted yarns (twist multiplier of 4.0), and the warp yarns 3 and 4 and the weft yarn C, D were twisted yarns (twist multiplier of 3.0) (comparative example 3).

A three-layer woven yarn was produced in which the warp yarns 1, 2, 3 and 4 and the weft yarn A, B, C, D were twisted yarns (twist multiplier of 4.0) and the warp yarns 5 and 6 and the weft yarn E, F were twisted yarns (twist multiplier of 3.0) (comparative example 4).

The three-layer woven fabric according to the first embodiment and the three-layer woven fabrics according to comparative examples 1, 2, 3, and 4 were compared in terms of the sewing properties. As a result, the three-layer knitted fabric of comparative example 1 was inferior in sewing. The sewn portion of the three-layer scrim garment of comparative example 1 was split with only a small pulling force applied. In contrast, the three-layer scrim of the first embodiment is well sewn. That is, the sewn portion of the three-layer scrim fabric of the first embodiment is not split. The three-layer yarn fabrics of comparative examples 2, 3 and 4 were also satisfactory in sewing.

The hand was compared between the triple-layer woven fabric of the first embodiment and the triple-layer woven fabrics of comparative examples 1, 2, 3 and 4. As a result, the three-layer woven yarn of the first embodiment (the warp and weft yarns of the surface layer yarn and the warp and weft yarns of the back layer yarn are twisted yarns having a twist multiplier of 3.0) has an excellent hand. In contrast, the triple layer yarn fabrics of comparative examples 2, 3 and 4 had poor hand. The flexibility was also poor. The twisted yarns 3 and 4 are rarely exposed from the surface (see fig. 1). However, the exposure ratio of the twisted yarns 3 and 4 is almost 0. Therefore, the hand feeling is poor.

In the three-layer woven yarn of the first embodiment, the surface layer yarn (back layer yarn) is formed of a twisted yarn having a twist multiplier of 3.0, and the intermediate layer yarn is formed of a twisted yarn having a twist multiplier of 4.0, so that the three-dimensional effect is strong. The heat retaining property is excellent because of the strong three-dimensional effect. And is also flexible. Also, although thick, it is lightweight.

The foregoing describes a three layer scrim fabric. However, the present invention may be an N-layer (N is an integer of 4 or more) yarn woven fabric. In this case, the yarns of the front and back layers are made of twisted yarns having a twist multiplier of 3.3 or less, and the yarn of at least one layer of the intermediate layer is made of twisted yarn having a twist multiplier of 3.5 or more. All the yarns in the intermediate layer may be twisted yarns having a twist multiplier of 3.5 or more. In the case where the intermediate layer is two or more layers, the yarn of at least one layer may be a twisted yarn having a twist multiplier of 3.5 or more. However, if the middle layer is a woven fabric of two or more N layers (N is an integer of 4 or more) and a woven fabric of three layers, the woven fabric of three layers is more preferable from the viewpoint of weight saving and cost.

Fig. 1 is a cross-sectional view of a yarn fabric in which warp yarns (lengthwise yarns) are combined. Fig. 2 is a cross-sectional view of a yarn fabric incorporating weft yarns (cross-yarns). The yarn fabric of figure 1 differs from that of figure 2 only in the use of warp yarn bonding or weft yarn bonding. Since other points are the same, detailed description is omitted. The above combination may also use both warp and weft yarns.

The scrim of FIG. 1 being yarn G₂And yarn G₁Connecting yarn G₂And yarn G₃Examples of linking. However, the surface layer yarn G may be the surface layer yarn G₁And back side layer yarn G₃Intermediate layer yarn G directly joined so as to be sandwiched therebetween₂The indirect connection mode.

In fig. 1, 2, the yarns are of different sizes. However, in the above embodiment, the warp yarns and the weft yarns have substantially the same size. However, the dimensions may also be different.
