Description

The present invention relates to a warp knitted fabric made of only synthetic fiber yarns having crimpability and having excellent free-cutting property, and clothing made by using the warp knitted fabric.

Fabrics that have excellent elasticity and have free-cutting properties that do not require cleaning up even after cutting are widely used in the clothing field, especially for clothing applications that fit the body such as sports and innerwear. As a knitted fabric having such excellent elasticity, a fabric having a free-cut property has been proposed, in which spandex is used as a part of the fabric and the spandex is fused to each other in the processing process to prevent fraying even after cutting. See Patent Document 1). However, since spandex has a strong elastic force, it is unsatisfactory in terms of wearability because it is tightened too much when worn and the fabric becomes heavy due to its high density. In addition, spandex has problems in handleability and durability, such as being brittle due to light or sweat.

Further, a fabric having excellent elasticity and recoverability has been proposed by using a warp-knit elastic fabric made of polyethylene terephthalate crimped yarn (see Patent Document 2). Since this fabric does not use spandex, the feeling of tightening when worn is reduced, an appropriate fit is obtained, wearing comfort is improved, and there is no concern about embrittlement or deterioration of toughness of spandex. Are better. However, when the fabric is cut, curling occurs at the edges of the fabric, making it difficult to sew, reducing the shape retention of the sewn product, and making the silhouette apt to deteriorate. There was a problem to use in.

In addition, in order to prevent the spread of fraying from the cut end of the warp knitted fabric without using spandex fibers, the cloth spring has a specific range of knitting density and stitch pitch of the ground structure and the ratio of stitch pitch to sewing. Materials have been proposed (see Patent Document 3). However, this cloth spring material has a problem in being used for clothing because the sewing thread is sewn into at least a part around the cut portion and the knitted fabric is not a knitted fabric in consideration of washing durability.

In addition, it has an edge that does not require edge termination, which is a cross-knitted elastic thread and inelastic thread, and the tear strength of the edge that does not require edge termination is improved, and the edge does not curl and expands and contracts to fit the body. Clothing having sex has been proposed (see Patent Document 4). However, since this garment contains elastic threads, it cannot have sufficient strength for hard-use applications such as sports, and the elastic threads deteriorate due to repeated wearing, washing, and storage for a long time. It had an easy task.

The present invention has been made in view of the above-mentioned current state of the prior art, and an object of the present invention is to have appropriate extensibility and elasticity even if the fabric does not contain spandex yarn, and the fabric is also made when cut. The purpose is to provide a comfortable knitted fabric that has the property that the edges are not easily frayed and curled, and that compensates for the shortcomings of the knitted fabric used for the specifications where the hem ends are left uncut.

As a result of diligent studies to achieve the above object, the present inventor has a crimping property of the expansion / contraction rate and the expansion / contraction restoration rate in a specific numerical range on the front reed and the back reed that form the ground structure of the warp knitted fabric. Using synthetic fiber threads, the fiber threads form needle loops on all courses and consist of a collateral structure accompanied by a sinker loop, with front reed total fineness / back reed total fineness and / or front reed. By setting the yarn expansion / contraction elongation rate / back reed yarn expansion / contraction ratio within a specific range, the evaluation of fabric damage after cutting is improved, curling in the warp direction is suppressed, and the free cut property is improved.

Hereinafter, the free-cut warp knitted fabric of the present invention will be described in detail.

The knitted fabric of the present invention is a warp knitted fabric knitted with two or more reeds consisting only of synthetic fiber threads having a stretch elongation rate of 20 to 150% and a shrinkage restoration rate of 15 to 100%. ..

The synthetic fiber yarn having a crimping property referred to here is a processed yarn in which long fibers are crimped by false twisting. In the present invention, by using the crimped yarn having the expansion / contraction rate and the expansion / contraction restoration rate in the above range, the crimping occurs due to the moist heat during the dyeing process, and the fabric can be apparently shrunk. The stretchability and stretch recovery of the fabric are further improved, and the part where the free loop is formed other than the crossed part intersects with the crossed part because the yarn becomes bulky due to high crimping. The thread in the loosened part becomes thinner, the loop is less likely to come off, and as a result, the loop is less likely to fray, and the filament end is less likely to come loose. If it is a synthetic fiber yarn that does not have crimping property, it is difficult to obtain elasticity because the yarn form is straight, and the yarn that constitutes the loop of the knitted fabric becomes slippery, so that the fabric is cut. It is not preferable because the thread tends to fray.

Synthetic fibers having crimpability may be subjected to general false twisting. The false twisting method may be any method such as a pin type, a friction type, a nip belt type, an air twisting type, etc., but at least the yarn used for the back reed yarn is a pin type and / or a low speed friction type temporary twisting method. It is preferable to use a twisting method. As a method of heat fixing, there are a method of false twisting and fixing only the first heater (1 heater false twist) and a method of heating both the 1st heater and the 2nd heater and fixing the false twist heat (2 heater false twist). Either method may be used. The heater temperature varies depending on the false twisting speed and the heating method, but a generally adopted temperature may be adopted, and the yarn temperature immediately after the outlet of the first heater may be set between 170 and 220 ° C. When the second heater is used, it is preferably in the range of −70 ° C. to + 0 ° C. with respect to the thread temperature immediately after the outlet of the first heater.
In order to obtain false twisted yarn having high crimpability, it is preferable to adopt a false twisting coefficient (K1) of 20000 to 35000 in the following formula. More preferably, it is 21000 to 33000.
T1 = K1 / (D) ^1/2
T1 = false twist number (T / m), D = fineness of yarn supplied for false twist processing (dtex)
The specific number of false twists is preferably 3000 to 5500 T / m, more preferably 3500 to 5000 T / m. If the number of false twists exceeds the above range, double twists and the like are likely to occur, and the crimp grade is likely to deteriorate. If it is less than the above range, it becomes difficult to obtain the crimping characteristics required for the present invention.

The expansion / contraction rate of the synthetic fiber having crimpability is 20 to 150%, more preferably 25 to 110%. If the expansion / contraction ratio is less than the above range, the bulkiness of the processed yarn becomes poor, gaps are likely to be formed at the looped part of the knitted fabric, and the loop is freed without intersecting the intersecting part of the loop. It is not preferable because the difference in the apparent diameter area of the part to be made becomes small, and as a result, the loops tend to fray on the cut surface of the knitted fabric. The higher the expansion / contraction rate, the bulkier the processed yarn, which is preferable because the looping portion of the knitted fabric is less likely to fray, but if it exceeds the above range, the knitted fabric becomes too thick, which is not preferable.

The expansion / contraction restoration rate of the synthetic fiber having crimpability is 15 to 100%, more preferably 25 to 100%. If the expansion / contraction restoration rate is less than the above range, the kickback property of the knitted fabric is deteriorated, an appropriate fit cannot be obtained, and the crimping property is poor, so that the single yarn at the end of the yarn is easily loosened. It is not preferable because the fabric damage of the cut surface becomes worse.

The knitted fabric of the present invention is a warp knitted fabric knitted with two or more reeds. A warp knitted fabric knitted with a single reed is not preferable because the elasticity of the fabric is improved, but the loops of the knitted fabric become single and easily frayed in the cut surface. Further, if the number of reeds is too large, the loops of the knitted fabric are less likely to fray, but the binding force becomes too high, and the elasticity of the fabric is hindered and the fabric tends to be heavy. Therefore, 3 or less reeds are preferable, and 2 reeds are more preferable.

The knitting structure of the knitted fabric of the present invention is a warp knitted fabric. With a round knitted fabric, the elasticity of the fabric is high, but since the loops are all open and the knitted fabric is loose, loop drops occur, and therefore the threads on the cut surface are easily frayed and curling is likely to occur. Not preferred. Further, in a woven fabric, curling at the edges of the fabric does not occur, but since the threads are not looped, the threads are easily frayed from the cut surface and the elasticity is poor, which is not preferable.

The knitted fabric of the present invention is characterized in that the fiber threads of the front reed and the back reed constituting the knitted fabric form a needle loop on all courses and are composed of a directional structure accompanied by a sinker loop. Since the fibrous threads of the front reed and the back reed form needle loops on all courses, needle loops can be formed with two threads, and the loops are tighter and less likely to fray. Further, when the needle loop is not formed in a part, the thread constituting the loop becomes one, the restraint of the loop becomes weak and it becomes easy to fray, and the sinker loop of the thread becomes long, so that the thread is not restrained. , It becomes easy to fray from there at the time of cutting.

Further, the knitted fabric of the present invention is characterized in that the knitted fabric of the present invention is composed of the same direction structure accompanied by the sinker loops of the front reed and the back reed. If the sinker loops of the front reed and the back reed are in different directions, the balance will be lost when the fabric is stretched in the course direction, and the edges of the fabric will tend to curl.

The knitting structure of the knitted fabric of the present invention may be a looping structure accompanied by a sinker loop, and the needle loop may be a combination of closed stitches and open stitches, but the front yarn is closed stitches and the back yarn is open stitches. It is preferable to have. This is because when the back yarn is opened, the curl in the vertical direction is further reduced as compared with the case where the back yarn is closed.

The knitted fabric of the present invention has a front reed yarn expansion / contraction / extension ratio / back reed yarn expansion / contraction / extension ratio of 0.1 or more and 1.1 or less. When the expansion / contraction ratio of the front reed yarn / the expansion / contraction ratio of the back reed yarn exceeds 1.1, the elongation ratio of the fabric is lowered and the fabric is easily curled. The expansion / contraction rate of the front reed thread / the expansion / contraction rate of the back reed thread is preferably 1.0 or less. The expansion / contraction rate of the front reed thread / the expansion / contraction rate of the back reed thread is preferably 0.2 or more. The reason why the elongation rate of the fabric is lowered is that the yarn of the back reed has a great influence on the elasticity of the fabric, so it is effective to arrange the yarn having a large expansion / contraction ratio of the yarn on the back reed. In addition, the curl of the fabric is affected by the balance of elasticity between the back reed thread and the front reed thread. Therefore, if the expansion / contraction rate of the front reed thread forming the sinker loop is larger than the expansion / extension rate of the back reed thread, the balance of the elasticity of the front and back of the fabric is lost, and it becomes easy to curl.

Further, in the knitted fabric of the present invention, the total fineness of the front reed yarn / the total fineness of the back reed yarn is preferably 0.1 or more and 1.1 or less. When the total fineness of the front reed yarn / the total fineness of the back reed yarn exceeds 1.1, the front yarn with a large swing of the sinker loop has a large loop and is easily frayed. Will get worse. In addition, the stretch kickback property of the fabric has a greater influence on the crimping force of the back reed than that of the front reed. Is improved. The total fineness of the front reed yarn / the total fineness of the back reed yarn is more preferably 1.0 or less. However, if the total fineness of the front reed yarn becomes extremely fine with respect to the total fineness of the back reed yarn, the balance between the front and back of the knitted fabric becomes poor and it becomes easy to curl. Therefore, the total fineness of the front reed yarn / the total fineness of the back reed yarn is more preferable. Is 0.2 or more, more preferably 0.3 or more.

In the knitted fabric of the present invention, it is preferable that the front reed has a plain cord structure, the back reed has a denby structure, and the front reed and the back reed accompany the same-direction half structure. By using a plain cord for the front reed, the fabric can be easily stretched, and the threads can be swung by two stitches, so that the threads overlap, the tear strength is stable, and the texture is soft. If the front reed is swung by one stitch, the fabric is likely to tear. In addition, the back reed can form a stable ground structure with a small amount of yarn by using a denby structure. If the back reed is a plain cord with two stitches, the fabric will be too thick. In addition, the half structure in which the front reed and the back reed accompany the fabric stabilizes the fabric and makes it difficult for the edges of the fabric to curl.

In the knitted fabric of the present invention, it is desirable that the elongation rate under a load of 490 cN is 20 to 50% in the vertical direction and 25 to 100% in the horizontal direction, and the recovery rate is 85 to 100% in both the vertical and horizontal directions. If the elongation rate is less than the above range, the product becomes cramped when worn as a product, and the wearing comfort is impaired. Further, if the recovery rate is less than the above range, cracks are generated on the surface of the fabric when the fabric is stretched during wearing, which impairs the appearance and deteriorates the fit.

When producing the knitted fabric of the present invention, it is preferable that the raw machine is dyed without undergoing a dry heat treatment step. Usually, in the case of dyeing a synthetic fiber knitted fabric, especially a polyester knitted fabric, a dry heat setting step is often included before dyeing. By setting it in the dry heat treatment process before dyeing, the dimensional stability is improved and it has the effect of preventing wrinkles. It becomes difficult to demonstrate. In addition, it is not possible to give sufficient shrinkage to the crimped yarn, and the yarn is easily pulled out from the loop of the fabric or the single yarn is easily frayed by being heat-set without sufficiently developing crimping. Further, when the crimping is reduced, it becomes impossible to obtain sufficient extensibility for the dough.

By adopting the above processing method, the knitted fabric of the present invention has high elasticity and is finished at high density. The density of the finished knitted fabric is preferably 50 vertical lines / inch or more, 40 horizontal lines / inch or more, and the basis weight is ^{preferably 80 to 250 g / cm 2.} More preferably, it is 60 vertical lines / inch or more and 45 horizontal lines / inch or more. More preferably, it is 65 vertical lines / inch or more and 50 horizontal lines / inch or more. If the density of the knitted fabric is less than the above range in the vertical and horizontal directions, the sinker loop of the fabric becomes long, and there are many parts where the yarn is not restrained in the cut surface of the fabric, so that the fabric is easily frayed. On the other hand, the higher the density of the knitted fabric, the more difficult it is for the cut surface at the edge of the fabric to fray, but on the contrary, the fabric becomes heavier. Therefore, the density of the knitted fabric is preferably 100 vertical lines / inch or less and 70 horizontal lines / inch or less. More preferably, it is 90 vertical inches / inch or less and 60 horizontal inches or less. If the basis weight of the knitted fabric exceeds the above range, it may feel heavy when worn or the fabric may become thicker, making it impossible to layer.

The crimpable synthetic fiber used for the knitted fabric of the present invention is preferably made of polyester. Polyester material is used in many clothing items and has excellent weather resistance and handleability. Polyester fibers consist of polyesters in which at least 80% or more of their constituent units are ethylene terephthalates, in particular polyethylene terephthalates made from terephthalic acid or functional derivatives thereof and ethylene glycol or ethylene oxide. It is preferable that it consists of ethylene. 2. Isophthalic acid, adipic acid, sepatic acid, azelaic acid, naphthalic acid, P-oxybenzoic acid, which are less than 20 mol%, preferably less than 10 mol%, in addition to terephthalic acid or a functional derivative thereof as an acid component. Add 5-dimethylterephthalic acid, bis (P-carboxyphenoxy) ethane, 2.6-naphthalenedicarboxylic acid, 3.5-di (carbomethoxy) benzenesulfonate or functional derivatives thereof, or glyco A copolymer in which divalent alcohols such as diethyleneglycol, propyleneglycol, 1.4-butanjiol, and 1.4-pyroxymethylcyclohexane are added as components of ethylene glycol. May be. Further, for example, it may be a copolymer to which an aromatic polyphosphonate is added to impart flame retardancy. Further, an antioxidant, a matting agent, a coloring agent, a dyeability improving agent, a flame retardant improving agent, an antistatic agent and the like may be added to these polymers.

Further, as the cross-sectional shape of the polyester filament (single fiber), any of a normal round cross-section, a polygonal cross-section, a multi-leaf cross-section, a flat cross-section, a hollow cross-section, and other special irregular cross-sections can be adopted.

Nylon may be used as the synthetic fiber having crimpability. Nylon material is used in many clothing, and has excellent weather resistance, soft texture, and excellent hygroscopicity. Examples of the nylon fiber include those made of polyamides such as nylon 6, nylon 66, nylon 46, nylon 12, nylon 610, nylon 612, or a copolymer thereof. Of these, nylon 6 and nylon 66 are preferably used.

The synthetic fiber having crimpability may be a semi-synthetic fiber as long as it is a long fiber. For example, a thread obtained by crimping rayon, tencel, Bemberg, or the like may be used. Further, yarn dyed yarn may be used, yarns mixed with fibers having different polymer types or dyeability may be used, or yarns may be mixed or knitted. As the synthetic fiber having crimpability, one or two or more yarns can be used as a combined twist, a pre-twisted yarn, a tail twist, and a pulling alignment.

By constructing the knitted fabric of the present invention as described above, the evaluation of the fabric damage after cutting described later is 1 to 7 at the beginning and the end of the knitting, and the curl property in the vertical direction described later is 0 to 20%. Can be achieved. The fabric damage evaluation after cutting here refers to the degree of fraying and curling of the end face of the fabric after washing by washing a knitted fabric cut into a rectangle of a certain size with a further cut of 45 degrees. It is an index compared with before washing. If the degree of damage to the fabric after cutting exceeds 7, the loops on the end faces of the fabric are frayed and the appearance quality is inferior, which is not preferable. Further, if the curl property of the cloth edge exceeds 20%, the cloth edge does not adhere to each other when the product is worn, and the fit is deteriorated and the appearance is impaired, which is not preferable.

When the knitted fabric of the present invention is used as a garment, it is preferable that the knitted fabric is used for a part or all of the garment in a state where the edges of the knitted fabric are left as they are cut. If the fabric is folded back at the edge of the product, it will be less likely to fray, but the fabric will be thicker only at the edges of the product, resulting in poor wearing comfort and appearance.

Next, the effects of the present invention will be specifically described with reference to examples, but the present invention is not limited thereto. The evaluation of the characteristic values in the examples was based on the following method.

<Evaluation of fabric damage after cutting>
