Description

Warp knitting

The present invention relates to a warp knitted fabric. In more detail, the present invention relates to a warp knitted fabric that contains elastic fibers but still contains cellulose fibers suitable for wearing in hot environments.

From the viewpoint of ease of wearing and not hindering exercise, the undergarment is ideally stretchable. Furthermore, the underwear that is considered to be the best in a hot environment requires not only elasticity but also excellent physical properties such as breathability, moisture absorption, contact coldness, and heat dissipation. However, in general, if the aim is to improve the air permeability, the surface becomes rough, and the contact coldness decreases, and if the yarn density is increased to increase the contact coldness, the texture of the fabric becomes thicker, and the heat dissipation decreases. It is not suitable for hot environments, and there is a problem that it is difficult to obtain an elongation suitable for putting on and taking off.

As a fabric suitable for wearing in a hot environment, a fabric containing cellulose fibers can be cited. However, since the strength of the cellulose fiber is small, the increase in the weight mixing ratio of the cellulose fiber will cause the strength of the braid to decrease. In addition, if the fineness of cellulose fibers or tie yarns is increased to ensure the strength, the texture becomes thick, so it becomes a knitted fabric that is not suitable for wearing in a hot environment.

Patent Document 1 below discloses a fabric having a cellulose mixing ratio of 20% by weight or more in terms of excellent heat environment. However, due to the low elongation of cellulose fibers, the woven fabric tends to age, and the recovery tends to decrease, so there is a concern that discomfort such as tightness may occur when stretched due to wearing. In addition, although there is a description that polyurethane fibers are contained in order to obtain an elongation suitable for wearing, there is no description about studies conducted to obtain elongation or recovery.

In addition, Patent Document 2 below discloses a woven fabric containing cellulose fibers in an amount of 5 to 25% by weight and protruding the cellulose fibers toward the surface to form irregularities on the surface in terms of being suitable for a hot environment. The knitted fabric is aimed at reducing the sticky feeling during sweating by increasing the unevenness of the surface, thereby improving the comfort, but the cold feeling performance is not good, so it is not suitable for wearing in hot environments.

On the other hand, the braid composed of three pieces of reed woven with synthetic fibers, cellulose fibers, and elastic fibers is not suitable for use in hot environments due to its thickened texture and reduced contact coldness and heat dissipation. Wearing tight clothing. In addition, when all the cellulose fibers are passed through the reed, the weight mixing ratio tends to increase, which may cause an increase in weight per unit area and insufficient strength. Therefore, researches have been conducted to reduce the mixing ratio of cellulose fibers. However, if the run length of cellulose fibers is set to a smaller structure, it is difficult to obtain an elongation suitable for wearing. (1 in 1 out) When the draw-out is used for sleying, unevenness is formed on the surface, the cold feeling is reduced, and the wearing feeling is impaired, so it is not suitable for wearing in hot environments.

Patent Document 3 below discloses a three-piece reed knit fabric containing synthetic fibers, cellulose fibers, and elastic fibers that contains cellulose fibers and is suitable for wearing in a hot environment and can be directly cut. However, except that the structure of the knitted fabric focuses on direct tailoring, so the structure of the knitted fabric is limited, there is no description to improve the heat dissipation or breathability that is important for wearing in a hot environment. Research conducted. In addition, in the usual knitting using three reeds as described above, the texture becomes thicker, the contact cold feeling and the heat dissipation decrease, so it does not become a knit fabric suitable for wearing in a hot environment.

[Effect of invention]

Although the warp knit fabric of the present invention contains elastic fibers, the warp knit fabric is excellent in hot environment.

Hereinafter, the embodiments of the present invention will be described in detail. The warp-knitted fabric of this embodiment is characterized in that it contains cellulose fibers, synthetic fibers, and elastic fibers and contains the cellulose fibers at a content rate of 10 to 25% by weight, and the knitting needle yarn loop of the warp-knitted fabric The surface occupancy rate of the cellulose fibers on the surface is 20% to 50%, and the average surface roughness of the loop surface of the knitting needle is 10.0 μm to 50.0 μm. The so-called cellulose fiber refers to a non-elastic fiber and a fiber with a maximum elongation of less than 100%. The cellulose fiber is not particularly limited, and examples thereof include yarns of short fibers of regenerated cellulose fibers such as rayon, cuprammonium, and bamboo fibers, and natural cellulose fibers such as cotton. The thickness of the cellulose fiber is preferably a fineness of 20 to 90 dtex. By setting the fineness range, it is a fabric having excellent bending flexibility, thinness, and excellent wearing feeling in a hot environment.

The cellulose fiber can be in the form of a single yarn in the form of raw silk and twisted yarn, or it can be in the form of a composite yarn with synthetic fibers as described below. The production method of the composite yarn is not particularly limited, as long as the compounding method according to the application such as compounding by interweaving or compounding by twisting is selected. The fineness of the composite yarn with synthetic fibers is preferably set to a fineness of 20 to 90 dtex, whereby a fabric with excellent bending flexibility, thinness and excellent wearing feeling in a hot environment can be obtained.

The synthetic fiber included in the warp knitting of this embodiment refers to a non-elastic fiber and has a maximum elongation of less than 100%. The synthetic fiber is not particularly limited, and examples thereof include polyester-based fibers such as polyester and polytrimethylene terephthalate, synthetic fibers such as polyamide fibers, and polypropylene, and such bright yarns can be arbitrarily selected (bright yarn), semi-dull yarn, full-dull yarn, etc. The cross-sectional shape of the fiber can also be round, oval, W-shaped, cocoon-shaped, hollow fiber, etc. The shape of the fiber is also not particularly limited, and it may be a raw yarn, a false twist, or other crimped yarn.

The warp knitted fabric of this embodiment is characterized by containing 10 to 25% by weight of cellulose fibers. By making the weight blending ratio of cellulose fibers in the woven fabric 10 to 25% by weight, it is possible to provide a cold sensibility suitable for hot environments while suppressing the rupture strength or wet friction caused by the increased weight blending ratio of cellulose fibers Decreased consumption properties such as toughness. The weight mixing ratio of cellulose is preferably 10-20% by weight, more preferably 12-20% by weight.

The warp knitted fabric of this embodiment is characterized in that the surface occupancy rate of the cellulose fibers on the loop surface of the knitting needle is 20 to 50%. To make the weight mixing ratio of cellulose to 10 to 25% by weight and the surface occupancy of cellulose fibers to be 20% to 50% means that cellulose fibers are efficiently arranged on the surface of the knitted fabric and woven. By this, it becomes a knitted fabric suitable for wearing in hot environments while suppressing the increase in the weight per unit area and thickness caused by the increase in the mixing ratio of cellulose fibers, and taking into account the higher contact cold feeling and higher heat dissipation. In addition, by making the surface occupancy rate of the cellulose fiber on the loop surface of the knitting needle 20% to 50%, the wet friction toughness can also be improved, and the consumption of products caused by repeated wearing such as wear can be suppressed. The above effect is further improved by making the surface occupancy rate of the cellulose fiber on the loop surface of the knitting needle 20% to 40%, and further improved by 30% to 40%.

The warp knit fabric of this embodiment is characterized in that the average surface roughness (San) of the loop surface of the knitting needle is 10.0 μm to 50.0 μm. The smaller San is, the smaller the unevenness of the loop surface of the knitting needle. By reducing the unevenness of the surface of the knitting needle yarn, not only the contact cold feeling is improved, but also the contact area with the skin becomes larger, the heat absorption from the skin becomes larger, so it becomes a fabric more suitable for wearing in hot environments. The average surface roughness (San) of the loop surface of the knitting needle is preferably 10 μm to 40 μm.

Regarding the warp knit fabric of this embodiment, the contact coldness value (hereinafter, also referred to as Q-max) of the knitting needle loop surface of the warp knit fabric is preferably 120 W/m ² ·°C or more. If the Q-max is 120 W/m ² ·°C or higher, the contact coldness is sufficient when wearing and when the product is picked up by hand. The Q-max of the loop surface of the knitting needle is preferably 140 W/m ² ·°C or higher.

Regarding the warp knit fabric of the present embodiment, the heat dissipation amount (hereinafter, also referred to as DHL or dry heat dissipation) of the knitting needle loop surface of the warp knit fabric is preferably 9.0 W/m ² ·°C or more. If the DHL is 9.0 W/m ² ·°C or higher, it becomes a knitted fabric that does not easily feel hot even if it is worn continuously. The DHL of the loop surface of the knitting needle is preferably 10.0 W/m ² ·°C or higher.

The average surface roughness (Sas) of the sinker loop surface of the warp knit fabric of this embodiment is 10 μm to 80 μm, and preferably the average surface roughness (San) of the knitting needle loop surface. The average surface roughness (Sas) of the sinker ring surface is more preferably 15 μm to 50 μm, and the ratio (Sas/San) of the San of the knitting needle ring surface to the Sas ring surface is preferably 1.0 to 1.5 , More preferably 1.1 to 1.5. If Sas/San is 1.0 to 1.5, it becomes a knitted fabric that maintains a high contact coldness of the loop surface of the knitting needle, and achieves an improved surface area utilizing irregularities, has higher heat dissipation, and is suitable for hot environments Next dress.

The warp-knitted fabric of this embodiment is formed by weaving cellulose fiber or cellulose fiber composite yarn using a drawing reed, thereby becoming a knitted fabric more suitable for wearing in a hot environment. The so-called threading reed refers to knitting in a threading state including a threading needle that does not allow the yarn to pass, such that one thread passes one thread with respect to the thread guiding needle attached to the thread reed. In the field of warp knitting, the term drawing needle is also used to mean the same as drawing yarn. In this specification, for example, if one is drawn through one, it will be described as "one in and one out", if two are drawn through one, it will be described as "2 in 1 out" if If one is drawn through three, it is recorded as "one entry and three exits". In addition, the case where all yarn guide needles pass the yarn is described as "All in". In this embodiment, the method of drawing is not particularly limited, as long as it is one in four out (1 in 4 out), one in five out (1 in 5 out), two in two out (2 in 2 out), etc., It can be selected according to the purpose or pattern.

With regard to the warp knit fabric of this embodiment, by arranging synthetic fibers in the first reed and cellulose fibers or their composite yarns in the second reed, a flat yarn loop is formed on the loop surface of the knitting needle, and a certain The surface area makes it easy to balance consumable physical properties such as contact coldness and wet friction strength that can be fully felt. In addition, by arranging cellulose fibers in the second reed, and weaving in the state of one in two out or one in three out, it is easy to make irregularities on the surface of the sinker ring, and the surface area becomes larger The contact area of the atmosphere becomes larger, and the knitting surface of the knitting needles efficiently dissipates the heat absorbed from the skin to the outer atmosphere of the knitted fabric. Furthermore, due to the formation of gaps in the knitted fabric, it becomes easy to maintain high air permeability.

The elongation force of the warp knitted fabric of this embodiment at 80% elongation is preferably 90 cN to 800 cN in the warp and weft directions, more preferably 100 cN to 600 cN, and still more preferably 120 cN to 400 cN . If the warp and weft directions of the woven fabric are both 90 cN to 800 cN, it becomes easy to take into account the soft stretch and resilience that can be significantly extended with a small amount of force required by the stretchable close-fitting clothing.

The elongation recovery rate of the warp knit fabric of this embodiment is preferably 80% or more in both the warp and weft directions. If the elongation recovery rate is 80% or more, it will be in a form that will not damage the undergarment due to wearing or movement and washing in the wearing state, and is suitable for use as a knitwear for undergarment. When knitting the knitted fabric of the present embodiment, from the viewpoint of improving the elongation recovery rate, the stroke length of the third reed elastic fiber is preferably 350 when the yarn stretch rate at warping is 0% The range of mm/480 latitude circle (course) to 500 mm/480 latitude circle is more preferably 400 mm/480 latitude circle to 480 mm/480 latitude circle. By weaving the elastic fiber as far as possible, the recovery of the knitted fabric can be improved, but excessive stretching of the elastic fiber will make the elongation force too large, so in order to become a suitable extension force for wearing Preferably, the tension of the elastic fiber at the time of weaving is appropriately selected according to the fineness or structure of the synthetic fiber, cellulose fiber, and elastic fiber.

The elastic fiber included in the warp knitting in this embodiment refers to a fiber different from synthetic fiber and having a maximum elongation of 100% or more. The polymer or spinning method of the elastic fiber is not particularly limited. Polyurethane-based and polyetherester-based elastic fibers can be used. For example, if it is a polyurethane-based elastic fiber, dry spinning can be used. Yarn or melt spinning. The elastic fiber is preferably at a normal processing temperature of about 180°C in a predetermined step in the dyeing process without impairing stretchability. Furthermore, functional elastic fibers having high stereotypes, deodorizing properties, and antibacterial properties by containing elastic polymers containing special polymers or powders can also be used. The fineness of the elastic fiber is preferably from 10 to 80 dtex, and more preferably from 15 to 60 dtex from the viewpoint of ease of manufacturing the knitted fabric. The elastic fiber used in this embodiment may contain an inorganic substance, and can be made into a woven fabric having the property of containing an inorganic substance.

Regarding the warp knit fabric of the present embodiment, the difference in fiber degree between the first reed synthetic fiber and the second reed cellulose fiber is 20 dtex or less, preferably the first reed synthetic fiber and the second reed fiber The ratio of the stroke length of plain fibers (stroke length of synthetic fiber of the first reed/stroke length of cellulose fiber of the second reed) is set in the range of 1.0 to 1.3, more preferably in the range of 1.0 to 1.2. Normally, when two or more reeds are used to weave into a warp knit fabric, at the portion where the yarn is threaded through the reed with one entry, two exits, or one entry and three exits, the overall denier of the yarn loop becomes larger. Therefore, it is generally difficult to form irregularities by mixing yarn loops of different sizes in the braid, and maintain the smoothness of the surface. However, in the warp knitting of the present embodiment, by combining the first reed The ratio of the stroke length of the synthetic fiber to the stroke length of the cellulose fiber of the second reed is set to 1.0 to 1.3, and the yarn loop of the cellulose fiber is suppressed from protruding greatly toward the loop surface of the knitting needle, and the thickness is reduced and the surface is achieved. Increased contact coldness caused by improved smoothness.

In the warp knitting fabric of the present embodiment, from the viewpoint of obtaining an actual contact cold feeling and an elongation that facilitates putting on and taking off, the loop density is preferably 90 wefts/inch to 130 wefts/ Inch (2.54 cm), more preferably from 100 weft circles/inch to 120 weft circles/inch. If the yarn loop density is 130 wefts/inch or less, it is easy to obtain sufficient elongation for wearing, and the thickness does not become thick, so it becomes a knitted fabric suitable for wearing in a hot environment. On the other hand, if it is more than 90 laps/inch, sufficient contact coldness can be obtained.

The weight per unit area of the warp knit fabric of this embodiment is preferably 110 g/m ² to 190 g/m ² , and more preferably 120 g/m ² to 180 g/m ² . If the weight per unit area is 190 g/m ² , the fabric will not become too thick, so it will not become sultry and the heat dissipation will be improved, and it is suitable for wearing in hot environments. On the other hand, if the weight per unit area is 110 g/m ² , it will become a woven fabric with improved fracture strength and practically no problem.

The thickness of the warp knitted fabric of this embodiment is preferably 0.40 mm to 0.70 mm, and more preferably 0.40 mm to 0.60 mm. If the thickness is 0.40 mm or more, there is no see-through and hard feeling when wearing it. On the other hand, if it is 0.70 mm or less, the weight per unit area will not become too large, and the air layer is not easily included between the skin and the fabric. Can obtain sufficient heat dissipation.

In the warp knitting fabric of the present embodiment, the structure of the first reed, second reed, and third reed is not particularly limited, and may be warp, warp, warp, and warp. However, when the tissue of the first reed is a tissue above the double-needle ring seam, the weight per unit area becomes larger and the texture becomes thicker, which is not suitable for wearing in hot environments. Therefore, the tissue of the first reed is preferred. It is a warp satin weave with flat or single-needle loop stitching.

The warp-knitted fabric of this embodiment can be knitted by Tricot and Raschel warp knitting machines, and can be knitted by these single needle bed warp knitting machines. The gauge of the knitting machine can be arbitrarily selected, but it is preferable to use a knitting machine with a pitch of about 24 to 36. If the gauge is thicker, the aesthetics of the braid is not good. With a high gauge of 36, the yarn loop becomes smaller, so the density of the knitted fabric increases, and the stretchability becomes poor. Therefore, it is not suitable for use as a woven fabric to be worn in an extended state, so it is more preferable to use 28 to 36 gauge. Warp knitting machine.

The warp knit fabric of this embodiment can also be dyed. As the dyeing and finishing method, the usual dyeing and finishing steps can be used, and the dyeing conditions corresponding to the fiber material used can be used. The dyeing machine used can also be a jet dyeing machine, a rope (wince) dyeing machine, a coating solution Any one of the dyeing machine. In addition, a processing agent that improves water absorption or flexibility can be used. [Example]

Hereinafter, the present invention will be specifically described by examples. Of course, the present invention is not limited to these embodiments.

Calculate the ratio of the weight of various yarns to the weight of all the yarns.

(2) Surface occupancy rate of cellulose fibers (cellulose surface exposure rate) Reactive dyeing of the knitted fabric (dark color reactive dyes 1% owf, sodium carbonate, sodium sulfate, bath ratio 1:40, 60°C×30 minutes), so that the cellulose fiber and other yarns can be identified by color And heat-set in such a way as to become the density before dyeing. The non-stretched woven fabric is arranged on the measuring table without wrinkles, and the digital microscope VR-3000 manufactured by KEYENCE Co., Ltd. is used to shoot at an arbitrary magnification to obtain 3D data. The depth at the time of acquiring 3D data is set to a depth range that can be detected. Using the analysis application VR-H1A made by KEYENCE Corporation, open the 3D data, specify the range of dyed cellulose fibers, and calculate the surface area of the cellulose fibers. In addition, the overall surface area is calculated by using the entire 3D data area as the analysis area. The surface area of the cellulose fibers obtained in the above manner and the overall surface area are based on the following formula: Cellulose fiber surface occupancy (%) = Cellulose fiber surface area/total surface area × 100 The surface occupancy rate of the cellulose fiber is calculated, and the value obtained by rounding the second digit after the decimal point of the calculated value is obtained. In the case where the knitted fabric is dyed, after decolorizing the cellulose fiber, heat setting is performed again in such a manner as to be the density before decolorization, and the measurement is performed.

For synthetic fibers and cellulose fibers, the length of the state where a load of 0.1 g is applied to the drawn yarn is taken as the stroke length. In addition, with respect to the elastic fiber, the load is not applied to the drawn elastic fiber, but the length of the state where the elastic fiber becomes a straight line due to its own weight is defined as the stroke length. The stroke length ratio is calculated by dividing the stroke length of the synthetic fiber measured by the above method by the stroke length of the cellulose fiber, and rounding off the second digit after the decimal point.

(7) Heat dissipation (DHL) The woven fabric cut into 15 cm × 15 cm is subjected to humidity control at 20°C × 65%, using KES-F7-II manufactured by Kato Tech Co., Ltd., using dry contact measured by thermal insulation The method is measured at a hot plate temperature of 30°C and an air flow of 0.3 m/sec, based on the following formula: Heat dissipation (W/m ² ·°C) = measured value (W/100 cm ² ·10°C) × (100/10), Calculate the heat dissipation of 1 m ² per fabric area under the temperature difference of 1℃. At this time, the braid is placed in such a way that the measurement surface of the hot plate and the braid face to face.

(8) Elongation force at 80% elongation The braid cut into a width of 2.5 cm × a length of 15 cm was used to hold both ends of the braid with a width of 2.5 cm using a tensile testing machine. At this time, the holding portion was held so that the distance between the holding portion became 10 cm, and it was repeatedly stretched and recovered 3 times at a tensile speed of 300 mm/min, and the forward stress and return stress up to 80% elongation were measured. Draw an elongation recovery curve, and set the stress at 80% elongation of the first elongation as elongation force.

(9) Determination of stretch recovery rate From the elongation recovery curve depicted in (8), read the residual elongation (%) after 3 elongation recovery, according to the following formula: Elongation recovery rate (%) = {(80-residual elongation rate) ÷ 80} × 100 And figure it out.
