Description

The present invention relates to warp knitted fabric. More specifically, the present invention relates to a warp knitted fabric containing cellulose fibers, which is suitable for wearing in a hot environment even though it contains elastic fibers.

It is desirable that the underwear has stretchability from the viewpoint of ease of wearing and not hindering exercise. Further, underwear that is optimal in a hot environment is required to have excellent physical properties such as breathability, hygroscopicity, cool contact feeling, and heat dissipation as well as stretchability. However, in general, if the surface is roughened to improve the air permeability and the cool contact feeling is reduced, and if the stitch density is increased to improve the cool contact feeling, the fabric becomes thick and the heat dissipation is lowered, so that it is not suitable for a hot environment. In addition, there is a problem that it is difficult to obtain an elongation suitable for attachment / detachment.

Examples of fabrics suitable for wearing in a hot environment include fabrics containing cellulose fibers. However, since the strength of the cellulose fibers is low, an increase in the weight mixing ratio of the cellulose fibers leads to a decrease in the strength of the knitted fabric. In addition, if the fineness of the cellulose fiber or the mating yarn is increased to ensure the strength, the fabric becomes thicker, which makes the knitted fabric unsuitable for wearing in a hot environment.

The following Patent Document 1 discloses a dough having a cellulose content of 20% by weight or more, which is considered to be excellent in a hot environment. However, since the cellulose fibers have low elongation and the knitted fabric tends to be worn out and recoverable easily, there is a risk of causing discomfort such as tightness when stretching due to wearing. In addition, although there is a description that polyurethane fibers are contained in order to obtain elongation suitable for wearing, there is no description of any device for obtaining elongation and recovery rate.

Further, Patent Document 2 below discloses a knitted fabric containing 5 to 25% by weight of cellulose fibers and forming surface irregularities by projecting the cellulose fibers to the surface, as being suitable for a hot environment. The knitted fabric aims to improve comfort by reducing the sticky feeling when sweating by increasing the unevenness of the surface, but it is not excellent in cooling sensation performance and is not suitable for wearing in a hot environment. ..

On the other hand, knitted fabrics made of synthetic fibers, cellulose fibers, and elastic fibers knitted using three reeds are thick and have a reduced cool contact feeling and heat dissipation, so they are suitable as underwear to be worn in a hot environment. No. Further, when the cellulose fibers are completely passed through the reed, the weight mixing ratio tends to be large, which may lead to an increase in basis weight and insufficient strength. Therefore, some measures have been taken to reduce the mixing ratio of cellulose fibers, but if the runner length of the cellulose fibers is a small structure, it is difficult to obtain elongation suitable for wearing, and thread removal such as 1 in 1 out is performed. When the reed is passed through, the surface becomes uneven, the cool contact feeling is lowered, and the comfort is impaired, so that it is not suitable for wearing in a hot environment.

The following Patent Document 3 discloses a knitted fabric of three reeds composed of a leasable synthetic fiber, a cellulose fiber, and an elastic fiber, which contains a cellulose fiber and is suitable for wearing in a hot environment. However, since the knitted fabric has a structure that emphasizes bleedability, the knitted fabric structure is limited, and there is a description of measures to improve heat dissipation and breathability, which are important for wearing in a hot environment. No. Further, as described above, in the knitting with three reeds, the knitted fabric is usually thick and the cool contact feeling and heat dissipation are lowered, so that the knitted fabric is not sufficiently suitable for wearing in a hot environment.

Hereinafter, embodiments of the present invention will be described in detail.
The warp knitted fabric of the present embodiment is a warp knitted fabric containing cellulose fibers, synthetic fibers, and elastic fibers and containing the cellulose fibers at a content of 10 to 25% by weight, and is a warp knitted fabric of the needle loop surface of the warp knitted fabric. The surface occupancy of the cellulose fibers is 20% to 50%, and the average surface roughness of the needle loop surface is 10.0 μm to 50.0 μm.
Cellulose fibers are inelastic fibers and refer to fibers having a maximum elongation of less than 100%. The cellulose fibers are not particularly limited, and examples thereof include regenerated cellulose fibers such as rayon, cupra, and bamboo fibers, and short fiber threads of natural cellulose fibers such as cotton.
The thickness of the cellulose fiber is preferably 20 to 90 dtex, and by setting this fineness range, the fabric is excellent in bending softness, thin and has an excellent wearing feeling in a hot environment.

The cellulose fiber can be in the form of a single yarn as a raw silk or a twisted yarn, or may be in the form of a composite yarn with a synthetic fiber described below. The method for producing the composite yarn is not particularly limited, and a composite method suitable for the intended use, such as a composite by interlacing or a composite by twisting, may be selected. The fineness of the composite yarn with the synthetic fiber is preferably 20 to 90 dtex, which makes it possible to obtain a fabric having excellent bending softness, thinness and excellent wearing feeling in a hot environment.

The synthetic fiber contained in the warp knitted fabric of the present embodiment is an inelastic fiber and refers to a fiber having a maximum elongation of less than 100%. The synthetic fiber is not particularly limited, and examples thereof include polyester fibers such as polyester and polytrimethylene terephthalate, and synthetic fibers such as polyamide fibers and polypropylene, and these bright yarns, semi-dull yarns, full-dull yarns and the like can be arbitrarily selected. The cross-sectional shape of the fiber can be any cross-sectional shape such as round, elliptical, W-shaped, cocoon-shaped, hollow yarn, etc., and the form of the fiber is not particularly limited, and the crimped yarn such as raw yarn and false twist It may be.

The warp knitted fabric of the present embodiment is characterized by containing 10 to 25% by weight of cellulose fibers. Since the weight mixing ratio of the cellulose fibers in the knitted fabric is 10 to 25% by weight, it has a cold feeling suitable for a hot environment, and has consumer characteristics such as burst strength and wet friction fastness due to an increase in the weight mixing ratio of the cellulose fibers. The decrease can be suppressed. The weight mixture of cellulose is preferably 10 to 20% by weight, more preferably 12 to 20% by weight.

The warp knitted fabric of the present embodiment is characterized in that the surface occupancy of the cellulose fibers on the needle loop surface is 20 to 50%. The fact that the surface occupancy of the cellulose fibers is 20% to 50% while the weight mixing ratio of the cellulose is 10 to 25% by weight described above means that the cellulose fibers are efficiently arranged and knitted on the knitted fabric surface. Means that. This makes the knitted fabric suitable for wearing in a hot environment by achieving both a high contact cooling sensation and high heat dissipation while suppressing an increase in basis weight and thickness due to an increase in the cellulose fiber mixing ratio.
Further, since the surface occupancy of the cellulose fibers on the needle loop surface is 20% to 50%, the fastness to wet friction is high, and it is possible to suppress the consumption of the product due to repeated wearing such as rubbing. The above effect is further enhanced when the surface occupancy of the cellulose fibers on the needle loop surface is 20% to 40%, and further enhanced when the surface occupancy is 30% to 40%.

The warp knitted fabric of the present embodiment is characterized in that the average surface roughness (San) of the needle loop surface is 10.0 μm to 50.0 μm. The smaller the San, the smaller the unevenness of the needle loop surface. By reducing the unevenness of the needle loop surface, not only the cool contact feeling is improved, but also the contact area that comes into contact with the skin is increased and the amount of heat absorbed from the skin is increased. Become. The average surface roughness (San) of the needle loop surface is preferably 10 μm to 40 μm.

The warp knitted fabric of the present embodiment preferably has a cool contact value (hereinafter, also referred to as Q-max) of the needle loop surface of the warp knitted fabric of 120 W / m ² · ° C. or higher. When Q-max is 120 W / m ² ° C or higher, the cool contact feeling at the time of wearing and at the moment of picking up the product is sufficient. The Q-max of the needle loop surface is preferably 140 W / m ² ° C. or higher.

The warp knitted fabric of the present embodiment preferably has a heat dissipation amount (hereinafter, also referred to as DHL or dry heat loss) on the needle loop surface of the warp knitted fabric of 9.0 W / m ^2. ° C. or higher. If the DHL is 9.0 W / m ² ° C or higher, the knitted fabric will not feel the heat even if you continue to wear it. The DHL of the needle loop surface is preferably 10.0 W / m ² ° C. or higher.

The warp knitted fabric of the present embodiment preferably has a sinker loop surface with an average surface roughness (Sas) of 10 μm to 80 μm and a needle loop surface with an average surface roughness (San) or more. The average surface roughness (Sas) of the sinker loop surface is more preferably 15 μm to 50 μm, and the ratio of San on the needle loop surface to Sa on the sinker loop surface (Sas / San) is preferably 1.0 to 1. It is 5, more preferably 1.1 to 1.5. When Sas / San is 1.0 to 1.5, it achieves surface area improvement due to unevenness while maintaining high contact coldness of the needle loop surface, has higher heat dissipation, and is suitable for wearing in a hot environment. It will be a suitable knitted fabric.

The warp knitted fabric of the present embodiment is a knitted fabric suitable for wearing in a hotter environment by knitting cellulose fibers or cellulose fiber composite yarns by threading a reed. Reed threading for thread removal refers to knitting in a threading state including a thread guide needle that does not allow threading, such as pulling out one thread through a thread guide needle attached to a reed. In the field of warp knitted fabric, the term needle pulling is also used in the same meaning as thread pulling. In the present specification, for example, "1 in 1 out" if one thread is removed, "2 in 1 out" if one thread is removed, and "2 in 1 out" if one thread is removed. Notated as "1 in 3 out". Further, threading through all the thread guide needles is referred to as "All in". In the present embodiment, the method of thread removal is not particularly limited, and may be appropriately selected according to the application and the pattern, such as 1 in 4 out, 1 in 5 out, and 2 in 2 out.

In the warp knitted fabric of the present embodiment, by arranging synthetic fibers on the first reed and cellulose fibers or composite yarns thereof on the second reed, a flat stitch is formed on the needle loop surface and a constant surface area is formed. In order to ensure the above, it becomes easy to achieve both a feeling of cool contact that can be fully felt and consumer characteristics such as fastness of wet friction. In addition, by arranging cellulose fibers on the second reed and knitting in a state of 1 in 2 out or 1 in 3 out, unevenness is formed on the sinker loop surface to improve the surface area and contact with the outside air. The area becomes large, and it becomes easy to make a knitted fabric that efficiently dissipates the heat absorbed by the needle loop surface from the skin to the outside air, and since gaps are formed in the knitted fabric, high air permeability is maintained. It becomes easy to do.

In the warp knitted fabric of the present embodiment, the elongation force at the time of 80% elongation is preferably 90 cN to 800 cN in both the warp and weft directions, more preferably 100 cN to 600 cN, and further preferably 120 cN to 400 cN. preferable. If both the warp and weft directions of the knitted fabric are 90 cN to 800 cN, it becomes easy to achieve both soft stretch that stretches well with a small force and recoverability, which are required for elastic underwear.

The warp knitted fabric of the present embodiment preferably has an elongation recovery rate of 80% or more in both the warp and weft directions. When the elongation recovery rate is 80% or more, the shape of the underwear is not impaired by wearing, movement during wearing, washing, etc., and the knitted fabric is suitable for use as underwear. From the viewpoint of improving the elongation recovery rate when knitting the knitted fabric of the present embodiment, the runner length of the elastic fiber of the third reed is 350 mm / 480 course to 500 mm / 480 when the yarn elongation rate during pacing is 0%. The range of the course is preferable, and it is more preferably 400 mm / 480 course to 480 mm / 480 course. By knitting the elastic fibers in a stretched state as much as possible, the recoverability of the knitted fabric can be improved. Therefore, it is preferable to appropriately select the tension of the elastic fiber at the time of knitting according to the fineness and structure of the synthetic fiber, the cellulose fiber, and the elastic fiber.

The elastic fibers contained in the warp knitted fabric in the present embodiment are different from synthetic fibers and refer to fibers having a maximum elongation of 100% or more. The polymer of the elastic fiber and the spinning method are not particularly limited, and polyurethane-based or polyether ester-based elastic fibers can be used. For example, as the polyurethane-based elastic fiber, dry-spun or melt-spun can be used. It is preferable that the elastic fiber does not impair its elasticity at around 180 ° C., which is the normal treatment temperature of the presetting step during the dyeing process. Further, since the elastic fiber contains a special polymer or powder, an elastic fiber having high settability, deodorant property, and antibacterial property can also be used. The fineness of the elastic fiber is preferably 10 to 80 dtex, and more preferably 15 to 60 dtex from the viewpoint of ease of knitted fabric production.
The elastic fiber used in this embodiment can contain an inorganic substance, and can be a knitted fabric in which the performance of the contained inorganic substance is taken into consideration.

In the warp knitted fabric of the present embodiment, the fiber degree difference between the synthetic fiber of the first reed and the cellulose fiber of the second reed is set to 20 dtex or less, and the ratio of the runner lengths of the synthetic fiber of the first reed and the cellulose fiber of the second reed. (The synthetic fiber runner length of the first reed / the runner length of the cellulose fiber of the second reed) is preferably in the range of 1.0 to 1.3, and more preferably in the range of 1.0 to 1.2. preferable. Normally, when a warp knitted fabric is knitted with two or more reeds, the fineness of the entire loop becomes large at a portion where the threads threaded through the reeds at 1 in 2 out or 1 in 3 out form a loop. Therefore, unevenness is formed by mixing loops of different sizes in the knitted fabric, and it is generally difficult to maintain the smoothness of the surface. However, in the warp knitted fabric of the present embodiment, the first reed is used. By setting the ratio of the synthetic fiber runner length to the runner length of the cellulose fiber of the second reed to 1.0 to 1.3, it is possible to prevent the loop of the cellulose fiber from protruding significantly to the needle loop surface, and to reduce the thickness. Achieves an increase in cool contact feeling due to improved surface smoothness.

In the warp knitted fabric of the present embodiment, the stitch density is preferably 90 courses / inch to 130 courses / inch (2.54 cm), and 100 courses / inch, from the viewpoint of obtaining a feeling of cool contact and easy attachment / detachment elongation. Inches to 120 courses / inch are more preferred. When the stitch density is 130 courses / inch or less, sufficient elongation for wearing is likely to be obtained, and the knitted fabric is not thick, so that the knitted fabric is suitable for wearing in a hot environment. On the other hand, if it is 90 courses / inch or more, a sufficient cool contact feeling can be obtained.

Basis weight of the warp knitted fabric of the present embodiment ^is preferably ^{110g / m 2 ~190g / m 2} , 120g / m 2 ~180g / m 2 is more preferable. When the basis weight is 190 g / m ² , the fabric does not become too thick, so that it becomes difficult to get stuffy, heat dissipation is improved, and the knitted fabric is suitable for wearing in a hot environment. On the other hand, if the basis weight is 110 g / m ² , the burst strength is improved and the knitted fabric has no problem in actual wearing.

The thickness of the warp knitted fabric of the present embodiment is preferably 0.40 mm to 0.70 mm, more preferably 0.40 mm to 0.60 mm. If the thickness is 0.40 mm or more, there is no see-through or strength when worn, while if it is 0.70 mm or less, the basis weight does not become too large, and an air layer is included between the skin and the fabric. It is difficult and sufficient heat dissipation can be obtained.

In the warp knitted fabric of the present embodiment, the organization of the first reed, the second reed, and the third reed is not particularly limited, and may be an organization such as a cord, a denbi, or an atlas. However, if the structure of the first reed is a structure with two or more stitches, the basis weight becomes large and the material becomes thick, which makes it unsuitable for wearing in a hot environment. Tissue is preferred.

The warp knitted fabric of the present embodiment can be knitted by a tricot or Russell warp knitting machine, and can be knitted by these single warp knitting machines. The gauge of the knitting machine can be arbitrarily selected, but it is preferable to use a knitting machine of about 24 to 36 gauge, and if the gauge is coarse, the aesthetic appearance of the knitted fabric is not good, and if the gauge of the knitting machine is higher than 36. As the stitches become smaller, the knitted fabric density increases and the elasticity becomes poor, which makes the knitted fabric unsuitable for use in clothing worn in the stretched state. More preferred.

The warp knitted fabric of the present embodiment may be dyed. As a dyeing finish method, a normal dyeing finishing process can be used, the dyeing conditions are set according to the fiber material used, and the dyeing machine used can be any of a liquid flow dyeing machine, a wins dyeing machine, a paddle dyeing machine, etc. Is. In addition, a processing agent that improves water absorption and flexibility can be used.

Hereinafter, the present invention will be specifically described with reference to Examples. Of course, the present invention is not limited to these examples.
Hereinafter, the method for measuring the characteristic value used in the examples and the like will be shown. The knitted fabric used for the measurement is a knitted fabric cut out from clothing, but the present invention also includes a knitted fabric that is not clothing.

(1) Weight mixing ratio of each fiber constituting the knitted fabric (cellulose mixing ratio)
Make a cut in the horizontal direction for 100 wells on the knitted ground, unwind the yarn type and number of yarns constituting the knitted structure from the knitted fabric, and measure the weight of each. The ratio of each yarn weight to all those yarn weights is calculated.

(2) Surface occupancy of cellulose fibers (cellulose surface exposure rate)
The knitted fabric is reactive dyed (dark reactive dye 1% owf, sodium carbonate, sodium sulfate, bath ratio 1:40, 60 ° C. x 30 minutes) so that the cellulosic fibers and other threads can be distinguished by color. Heat set to the density before dyeing. Place the knitted fabric in the non-stretched state on the measuring table so that there are no wrinkles, and take a picture with a digital microscope VR-3000 manufactured by KEYENCE CORPORATION at an arbitrary magnification to acquire 3D data. The depth at which 3D data is acquired shall be the entire detectable depth. With the analysis application VR-H1A manufactured by KEYENCE CORPORATION, 3D data is opened, the range of the dyed cellulose fibers is specified, and the surface area of the cellulose fibers is calculated. The total surface area is calculated by setting the entire 3D data as the analysis area. From the surface area of the cellulose fibers obtained as described above and the total surface area, the following formula:
Cellulose fiber surface occupancy (%) = Cellulose fiber surface area / total surface area x 100
The surface occupancy of the cellulose fiber is calculated by the above method, and the value obtained by rounding off the second decimal place of the calculated value is obtained.
When the knitted fabric is dyed, the cellulose fibers are decolorized and then heat-set to the density before decolorization for measurement.

(3) Average surface roughness Sas and San
Place the unstretched knitted fabric on the measuring table so that there are no wrinkles, take a picture with a digital microscope VR-3000 manufactured by KEYENCE Co., Ltd. at an arbitrary magnification, and in the measurement mode, 3D of the knitted fabric surface. Take a picture of the data. The surface roughness (arithmetic mean height = Sa) is analyzed from 3D data by the analysis application VR-H1A manufactured by KEYENCE CORPORATION. At this time, the surface area for analyzing 3D data is set as the photographing area. The depth region for analyzing 3D data is the entire detectable depth.

(4) Thickness (mm)
With a PEACOCK knitted fabric thickness gauge, three arbitrary positions of the knitted fabric are measured, and the average value of the three locations is calculated.

(5) Runner length and runner length ratio Synthetic fibers, cellulose fibers, and elastic fibers in the knitted fabric were extracted with the same course length. For the synthetic fiber and the cellulose fiber, the length in which a load of 0.1 g was applied to each of the extracted threads was defined as the runner length. As for the elastic fiber, the runner length was defined as the length in which the elastic fiber became a straight line due to its own weight without applying a load to the extracted elastic fiber.
The runner length ratio is calculated by dividing the runner length of the synthetic fiber measured by the above method by the runner length of the cellulose fiber and rounding off to the second decimal place.

(6) Maximum heat transfer amount (Q-max)
The knitted fabric cut to 8 cm x 8 cm was humidity-controlled in an environment of 20 ° C. x 65%, and the hot plate of the device heated to the environmental temperature + 10 ° C. was knitted using KES-F7-II manufactured by Katou Tech Co., Ltd. Place it on the measurement surface and measure it.
Maximum heat transfer amount ^{(W / m 2 · ℃)} = measured value ^{(W / cm 2 · 10 ℃} ) × (10000/10)
The maximum heat transfer amount (W / m ² · ° C.) ^{per 1 m 2} of the dough area at a temperature difference of 1 ° C. is measured.

(7) Heat dissipation amount (DHL)
The knitted fabric cut to 15 cm x 15 cm is humidity-controlled in an environment of 20 ° C. x 65%, and using KES-F7-II manufactured by Katou Tech Co., Ltd., the hot plate temperature is 30 ° C. and the air volume is 0 by the dry contact method for heat retention measurement. Measured at 3 m / sec, the following formula:
Heat radiation amount ^{(W / m 2 · ℃)} = measured value ^{(W / 100cm 2 · 10 ℃} ) × (100/10)
Therefore, the amount of heat released per ^{1 m 2} of the dough area at a temperature difference of 1 ° C. is calculated. At this time, the knitted fabric is set so that the hot plate and the measurement surface of the knitted fabric face each other.

(8) Stretching force at 80% stretching A knitted fabric cut into a width of 2.5 cm and a length of 15 cm is gripped at both ends of the knitted fabric with a width of 2.5 cm using a tensile tester. At this time, the grip is gripped so that the distance between the grips is 10 cm, stretching and recovery are repeated three times at a tensile speed of 300 mm / min, and the outward stress and the return stress up to an elongation rate of 80% are measured to recover the stretch. A curve was drawn, and the stress at the elongation rate of 80% at the first elongation was used as the elongation force.

(9) Stretch recovery rate measurement From the stretch recovery curve drawn in (8), read the residual stretch (%) after three stretch recovery, and use the following formula:
Elongation recovery rate (%) = {(80-residual elongation) ÷ 80} × 100
Calculated by
