Description

  The present invention relates to a skin-friendly knitted fabric or a garment made of the knitted fabric, particularly an undergarment, which is difficult to feel unevenness, a tingling feeling, a rough feeling, a rubbing feeling, etc. during wearing, attaching / detaching, and wearing operation.

  Clothing that directly touches the skin, particularly underwear, is the clothing closest to the skin, and a highly elastic knit fabric is used so as to follow the elongation of the skin during the wearing operation. Milling, smooth, tempura, and more recently Kanoko are examples of fabrics for underwear.

Among them, organizations such as milling, smooth, and tengu are common from the viewpoint of production equipment, productivity, versatility, and consumption performance. Especially for tengu, a bare knitted fabric with polyurethane elastic fibers inserted into the tenji with a single knitting machine can be finished into a knitted fabric that fits the body thinner than bare mill and bare smooth. .
Tendon tissue including a bare tenon is generally arranged with the side corresponding to the outer side of the knitted fabric at the time of knitting, and the stitches of the needle loop are regularly arranged like a V-shape. On the other hand, the side that hits the inside when knitting is the back, and the sinker loop and a part of the needle loop are arranged in a semicircular shape (arch shape) in the weft direction of the fabric. The back is generally sewn on the skin side from the viewpoint of appearance.

  By the way, in the case of clothing that directly touches the skin with the back side as the skin side, the back in which the semicircular stitches are arranged in the weft direction and the table in which the V-shaped stitches are regularly arranged in the warp direction are completely soft to the touch. Different. The reason for this is that the friction coefficient in the back warp direction is higher than that in the front and slipping is poor (for example, see Non-Patent Documents 1 and 2 below). That is, it is considered that the friction coefficient in the longitudinal direction of the back also leads to worsening the touch when attaching / detaching or raising the arm.

  Conventionally, there are reports of fabrics that focus on reducing friction between skin and fabric. For example, focusing on reducing the stickiness with the skin that occurs when the fabric is wet by sweating, a method of imparting irregularities with a certain height difference or more on the surface of the fabric that contacts the skin (for example, the following patent document) 1), a method of reducing stickiness by reducing the contact area with the skin, reducing frictional resistance with the skin, and simultaneously sucking up sweat from the skin (for example, see Patent Document 2 or 3). . Fabrics made from these methods have been developed from the idea of imparting irregularities to make the skin side point contact, and reducing the physical coefficient of friction even when the fabric is wet. However, it has not been taken into account how the uneven fabric affects human touch.

  The problem to be solved by the present invention is to pay attention to the tactile sensation that occurs when people actually wear it regardless of the presence or absence of sweat on the skin or the wetness of the fabric. It is to provide a knitted fabric with a reduced feel.

  In order to develop a knitted fabric that can enhance the tactile sensation when actually worn by humans, the inventor passes the sleeve when wearing, slides the clothing on the skin, stretches the hand during operation, stands up, etc. Focusing on the need to consider the tactile sensation caused by the warp movement of the back side of the knitted fabric, as a result of intensive studies and experiments, in order to improve the feel, the positional relationship between the loops appearing on the back side is controlled. This has led to the development of a knitted fabric with a good feel during wearing operation.

When the back side of the knitted fabric of this embodiment is folded in half with respect to the wale direction (warp direction) as the axis, and observed with a microscope, attention is paid to the adjacent needle loop and sinker loop, and the inclination aN of the center portion of the needle loop with respect to the vertical direction It is a photograph replacing a drawing for explaining a procedure for reading ° and the inclination aS ° of the center part of the sinker loop with respect to the vertical direction. Drawing for demonstrating the procedure of reading the distance D of the center part of an adjacent needle loop and a sinker loop when observing with the microscope which folds in half with the wale direction (warp direction) on the back of the knitted fabric of this embodiment as an axis | shaft This is an alternative photo. In order to explain the procedure of reading the height difference ΔH between the center portions of adjacent needle loops and sinker loops when observing with a microscope that is folded in half with the wale direction (warp direction) on the back of the knitted fabric of this embodiment as an axis It is the photograph replaced with drawing of.

Hereinafter, embodiments of the present invention will be described in detail.
The knitted fabric of this embodiment is composed of a tengu structure, and the positional relationship between a sinker loop disposed adjacent to the waling direction on the back of the knitted fabric (the side that contacts the inside when knitting down) and a semicircle of a part of the needle loop There is a feature. Regarding the angle between the loops, the inclination aN ° with respect to the vertical direction of the center part of the needle loop and the sinker loop with respect to the adjacent needle loop and sinker loop when the back surface of the knitted fabric is folded in two with respect to the wale direction as an axis. It is necessary that the sum of the inclinations aS ° of the central portion with respect to the vertical direction be aN + aS ≦ 40 °, and more preferably 35 ° or less. Regarding the distance between the loops, similarly, the distance D between the center portions of the adjacent needle loops and sinker loops when observed by folding in two with the wale direction on the back of the knitted fabric as an axis needs to be D ≦ 350 μm. Yes, more preferably 300 μm. The smaller the angle and the distance, the easier it is to feel smoothness when stroking the knitted fabric in one direction against the wale.

Further, when the back surface of the knitted fabric is folded in two with the wale direction as the axis and observed, the difference ΔH in height between the center portions of adjacent needle loops and sinker loops is further smooth if ΔH ≦ 110 μm is satisfied. Is more preferably 90 μm or less.
If this positional relationship is maintained, even when the fabric is bent or slid on the skin, no bad tactile sensation such as tingling or roughness is given.

In order to reduce the angle and the distance between the loops, it is necessary that the yarn bend is soft. Therefore, it is preferable to select a thin constituent yarn and a single constituent yarn.
In the case of long fiber yarns, the total fineness is 122 dtex (decitex) or less, more preferably 84 dtex or less, and the single yarn fineness constituting it is preferably 2 dtex or less. The constituent yarn may be either a raw yarn or a processed yarn. In addition, since the section of the constituent yarn reduces friction with the skin, a shape such as a circle or an ellipse having no corner is more preferable than a cross-sectional shape having a corner such as a triangle or a cross. Examples include polyamide-based, polyester-based, acrylic-based, regenerated cellulose long fibers, etc., but if you want to combine two or more types of long fiber yarns, combine them into one yarn in advance with air, heat, and twisting device. It is preferable to keep it. The reason is that differences such as fiber-specific shrinkage differences, fiber-specific shrinkage differences, swelling differences, crimp characteristic differences, and the like affect the loop shape of the back surface.

As a method of compounding into one yarn, for example, regenerated cellulose long fiber and synthetic long fiber such as polyamide, polyester, and acrylic are intertwisted, interlaced, interlaced mixed after false twist, interlaced mixed Examples of the method include compounding by methods such as post false twisting, interlace mixed post-twisting, and fluid mixing by fluid disturbance processing.
As a composite combination, from the viewpoint of wearing comfort described later, a composite yarn of regenerated cellulose long fiber and polyester long fiber is used. From the viewpoint of wearing comfort, particularly hygroscopicity and bending softness, regenerated cellulose is used. A composite yarn of long fiber and polyamide long fiber is preferable, and a half (partial) drawn yarn (POY) may be used as the synthetic fiber.

  As the short fiber yarn, a fine count such as 40 or more, more preferably 50 to 80 is preferable. It is preferable that the single yarn which comprises it also consists of 2 dtex or less. In order to eliminate fiber fluff as much as possible, the fiber length is preferably 25 mm or more, and more preferably 38 mm or more. Examples of the material include cellulosic staples, polyester staples, acrylic staples, nylon staples, and composite staples thereof. In any case, fibers having a cross-sectional shape without corners are preferable. At this time, the number of twists of the constituent short fibers is preferably 18 / inch or more and 30 / inch or less from the viewpoint of yarn hardness and texture. This short fiber can be combined with the above-mentioned long fiber on the machine, but in order to simplify the control of the loop shape, a single yarn is preliminarily formed by a fine spinning and twisting technique, and the fluff of the short fiber is long fiber. It is preferable to wrap with.

For the purpose of imparting elongation and stretch recovery as a constituent yarn and improving the fit and movement following ability, it is also possible to barely insert polyurethane elastic fiber, the above-mentioned long and short fiber yarns are sheath yarn, polyurethane elastic It is also possible to perform knitting after previously processing into a covering yarn having fibers as core yarns. The thickness of the polyurethane elastic fiber is preferably 33 dtex or less, more preferably 22 dtex or less in order not to stretch and harden the fabric. The polyurethane elastic fiber is more easily adapted to the tissue if it is composed of two or more filaments than monofilaments.
The mixing ratio of the polyurethane elastic fibers is preferably 30% or less of the fabric weight, but is preferably 5% or more and 20% or less in consideration of an appropriate fit when worn.

Difference in height between adjacent needle loop and sinker loop height ΔH
In order to reduce the length, it is necessary to select a knitting machine with a fine knitting machine gauge and increase the C number and W number, depending on the trial knitting conditions of the constituent yarn thickness. The C number is preferably 60 or more and 90 or less, and the W number is preferably 40 or more and 70 or less. The knitting machine is preferably a machine capable of knitting fine loops such as 28, 32, 36, 40, 44, 48, 52, 56, 60G. Considering balance with physical properties such as consumption performance and burst strength, 28G or more and 48G or less are preferable. Further, it is preferable that the stitch loop is smooth so as not to project three-dimensionally from the knitted fabric plane. For this purpose, the knitting length R of 100 wales described later is preferably 310 mm or less, more preferably 300 mm or less, and even more preferably 280 mm or less and 120 mm or more. When R is 120 mm or more and 310 mm or less, the loop is difficult to jump out from the knitted fabric back plane. If it is less than 120 mm, the stretchability is reduced and the paper is like paper. R can be basically adjusted by the yarn supply amount and tension at the time of knitting, and the draft rate of the polyurethane elastic fiber, but can also be finely adjusted at the time of presetting before dyeing or drying after dyeing. .

  It is preferable that the constituent yarns are made of yarns having the same thickness and the same yarn bending characteristics because the difference in loop angle, distance, and height can be easily controlled. Further, when compared with the same thickness, the long fiber yarns tend to be softer than the short fiber yarns, which are a collection of twisted yarns. Accordingly, it is preferable that at least one kind of long fiber yarn is included in the knitting.

  In the knitted fabric of the present embodiment, it is preferable that 20% or more of cellulose fibers, particularly cellulose fibers belonging to the cellulose II type and having high moisture absorption / release properties are mixed. The reason is that cellulose fiber belonging to cellulose type II has a very high moisture absorption / release speed, absorbs insensitive moisture from the skin, and releases it to the outer layer to control the temperature and humidity in the vicinity of the skin. Because. This humidity control function is realized when the mixing ratio of cellulose fibers is 40% or more, and the effect can be greatly exerted when the mixing ratio is 60% or more. Cellulose fibers are even more preferable from the viewpoint of reducing friction with the skin as long fiber yarns with few fiber fluff. Examples of the cellulose fibers include cotton, and cellulose fibers belonging to cellulose type II include cupra, viscose rayon, polynosic rayon, purified rayon, and high-strength rayon.

Dyeing of the knitted fabric of this embodiment is performed in the order of scouring, dyeing, finishing, and final set.
When polyurethane elastic fibers are included in the knitted fabric, it is advisable to appropriately perform a pre-setting treatment before scouring. A processing machine used for scouring and dyeing is preferably a low-tensioning machine such as a generally used liquid dyeing machine or a continuous scouring machine.
Prior to dyeing, a step of increasing whiteness by bleaching and bleaching may be added. As the dye, the dyeing assistant, and the finishing agent, those developed for dyeing synthetic fibers and / or cellulose fibers that are commercially available can be arbitrarily selected. Prior to dyeing, treatment such as alkali treatment for improving the dyeability of the regenerated cellulose fiber and alkali weight reduction processing for polyester fiber for improving the texture may be performed. It is also possible to use a water-absorbing agent or a softening agent in a dye bath, and pad these after soaping. The use of a softening agent is effective for enhancing the touch and flexibility. At the time of final setting, the dough may be appropriately drawn out in order to make the dough flat. As smoothing of the dough, calendaring with paper, felt, plast, etc. may be performed.

  The knitted fabric of this embodiment is preferably used for apparel such as underwear that directly touches the skin. In particular, it can be used for underwear such as undershirts, camisole, shorts, briefs, body cloths for bras, arm covers, spats and the like. It is also suitable for those who are sensitive to touch, such as infants, women and the elderly.

Although the basis weight of the knitted fabric of the present embodiment is not particularly limited, but is preferably about 100 g / ^{m 2} ~ about 200 g / ^{m 2,} more preferably about 110g / ^{m 2} ~ about 170 g / ^{m 2.} If the basis weight is too small, the sweat treatment function is inferior, the bursting strength is small, and there is a problem in consumption performance. On the other hand, if the basis weight is too large, the thickness becomes too thick, the wearing operability is inferior, and the outer appearance is affected.

EXAMPLES Hereinafter, the present invention will be specifically described with reference to examples, but the present invention is not limited only to these examples. First, the measurement method and the evaluation method used in the examples will be described.
(1) Sum of angles between loops (aNS °)
Cut the back of the knitted fabric into a size that is easy to observe and fold it in half with the wale direction (warp direction) as the axis. With a microscope, more preferably with a microscope provided with a 3D analysis function, the dough folded in half is placed on a stage, and a slide glass is gently placed from above. Focus on the highest curvature of the knitted fabric. The magnification is preferably 100 to 200 times, particularly 130 to 150 times because it is easy to observe. Focusing on the adjacent needle loop and sinker loop, the inclination aN ° of the center portion of the needle loop with respect to the vertical direction and the inclination aS ° of the center portion of the sinker loop with respect to the vertical direction are read, and their sum aNS ° = aN ° + aS. Determine ° (see Figure 1). The inclination can be easily obtained by using an image analysis function provided to the microscope. If there is no function, the image may be read after printing after reading the image. The angle between 20 loops of the needle loop and sinker loop is read at random in the same knitted fabric, and aNS ° is averaged.

(2) Distance between loops D (μm)
Cut the back of the knitted fabric into a size that is easy to observe, and fold it in half with the wale direction (warp direction) as the axis. With a microscope, more preferably with a microscope provided with a 3D analysis function, the dough folded in half is placed on a stage, and a slide glass is gently placed from above. Focus on the highest curvature of the knitted fabric. The magnification is preferably 100 to 200 times, particularly 130 to 150 times because it is easy to observe. Read the distance D between adjacent needle loops and the center of the sinker loop (see FIG. 2). The distance D can be easily obtained by using an image analysis function provided to the microscope. If there is no function, the image may be read after printing after reading the image. The distance between 20 loops of the needle loop and sinker loop is read and averaged at random in the same knitted fabric.

(3) Height difference between loops ΔH (μm)
Cut the back of the knitted fabric into a size that is easy to observe and fold it in half with the wale direction (warp direction) as the axis. With a microscope, more preferably with a microscope provided with a 3D analysis function, the dough folded in half is placed on a stage, and a slide glass is gently placed from above. Focus on the highest curvature of the knitted fabric. The magnification is preferably 100 to 200 times, particularly 130 to 150 times because it is easy to observe. Read the height difference ΔH between the center portions of the adjacent needle loop and sinker loop (see FIG. 3). The difference in height can be easily obtained by using the image analysis function provided to the microscope. If there is no function, the image may be read after printing after reading the image. The height difference between 20 loops of needle loops and sinker loops is randomly read and averaged in the same knitted fabric.

(4) Weaving length R (mm)
The basis weight (g / m ² ), the number of courses (C number) (pieces / inch), and the number of wales (W number) (pieces / inch) are measured.
Subsequently, the number of loops per 1 m ² is calculated. The fineness (dtex) of the yarn A used for knitting and the material mixture ratio (%) are examined. From the basis weight, the fineness of the yarn A, and the mixing ratio of A, the length existing in 1 m ^{2 of} the yarn A is calculated. By dividing this length by the number of loops per 1 m ² described above and multiplying by 100, the knitting length R in 100 wales is calculated.
For example, the weight per unit area is 150 g / m ² , C / W = 60/50, yarn A fineness: 84 dtex, polyurethane elastic fiber B: 22 dtex, and knitted by a 28G knitting machine. , B: When 10%,
60 × (100 / 2.54) × 50 × (100 / 2.54) = 4650009 (pieces), 150 g × (90/100) = 135 (g),
(135 g / 84 dtex) × 10000 = 1607.429 (m),
1607.429 / 4650009 × 1000 = 3.46 (mm)
The braiding length R = 3.46 × 100 = 346 (mm) is obtained.

In the case of a knitted fabric knitted with a composite yarn in advance, it can be calculated using the fineness of the composite yarn.
For example, with a basis weight of 140 g / m ² , C / W = 70/60, yarn C fineness: 56 dtex, yarn D fineness: 56 dtex, interlace false twist, polyurethane elastic fiber B: 22 dtex When the material mixture ratio is C: 45%, D: 45%, B: 10%
70 × (100 / 2.54) × 60 × (100 / 2.54) = 6510013 (pieces)
140 g × (45 + 45) / 100 = 126 (g),
(126 g / 112 dtex) × 10000 = 111250 (m),
From 11250/6510013 × 1000 = 1.73 (mm),
The braiding length R = 1.73 × 100 = 173 (mm) is obtained.
When knitting every other piece or two-to-one on the machine, it is possible to calculate each constituent yarn thickness and blend ratio for each yarn.
All weights are measured in a temperature-controlled room at 20 ° C. and 65% RH.
