Description

  The present invention relates to a cellulosic interwoven fabric that can be washed with domestic water and has excellent wearing comfort.

  Fabric made of cellulose fibers has many features such as high color development, unique texture, high moisture absorption and anti-static performance, and good slipperiness, but on the other hand, it tends to shrink or wrinkle during washing. Also, there is a disadvantage that it is inferior in strength. In order to improve these, various techniques for improving the shrinkage resistance and wrinkle resistance by applying resin cross-linking by post-processing have been studied. However, as far as the present inventors know, high-mixed cellulose fibers are washed with water at home. No one has reached the technical level at which washing (hereinafter simply referred to as water washing) is possible. On the other hand, fabrics made of synthetic fibers do not have the characteristics of cellulose fibers, but have excellent physical properties in terms of strength and shrinkage. In recent years, for the purpose of imparting the respective advantages of cellulose fibers and synthetic fibers, development of composite mixed yarns by air processing, false twisting, and the like has been advanced. However, it is not used for highly versatile applications because it is too costly to produce a composite blended yarn and the unique texture of cellulose fibers cannot be produced.

On the other hand, a woven fabric using cellulose fibers and synthetic fibers for either warp and / or weft is disclosed in, for example, Patent Document 1 as a woven fabric utilizing the characteristics of both. In the case of these fabrics, fabrics that can be washed with home water can be obtained. However, since the mixing ratio of cellulose fibers is around 50%, it is difficult to say that the fabrics are sufficiently satisfactory from the viewpoint of texture, hygroscopicity, and antistatic properties. is there.
As a method for increasing the mixing ratio of cellulose fibers in union woven fabrics, Patent Document 2 discloses a method in which a single synthetic fiber and synthetic filament are alternately used for warp yarns, and a thick yarn is used on the cellulose fiber side. ing. According to the embodiment, an example in which one weft side is alternate or mixed yarn is used is disclosed. Cellulose fiber mixing ratio is calculated to be 54.7% to 71.4%, which has good quality and texture, and the shrinkage rate of washing is 0% for both the background and the abrasion resistance is grade 5. . Although there is no specific description of washing performance such as washing wrinkles, it is estimated that the washing performance is at a level that allows washing. However, it is clear that there is almost no stretchability in the weft direction from the viewpoint of the amount of processability in the examples, particularly the change in warp density, and it is clear that the wearing comfort is low. In addition, according to the description of the patent document, the texture and physical properties of the fabric are more strongly affected by the warp. Therefore, even if the synthetic filaments and synthetic filaments are alternately arranged only on the wefts, the synthetic fibers It is said that the advantages of synthetic fiber cannot be fully extracted, and in the present invention, it is essential to use one warp alternately. In addition, the single warp alternating fabric has the disadvantage that warp preparation tends to occur locally due to the difference in wet and dry characteristics between the synthetic filament and the synthetic filament during the weaving process, because warp preparation is complicated. It does not have versatility.

JP-A-6-25937 Japanese Patent Laid-Open No. 7-42044

  As described above, in the prior art, there has never been a cellulosic interwoven fabric that can be washed in the home while maintaining the characteristics of cellulose fiber and has excellent wearing comfort. . In consideration of them, the present invention has an object to provide a cellulosic interwoven fabric that can be washed with water at home and that has an appropriate stretch in the weft direction and has improved wearing comfort.

As a result of intensive studies to solve the above problems, the present inventors have introduced a small amount of synthetic fiber into the cellulose fiber during weaving, and by performing appropriate width-filling treatment and epoxy-modified silicone treatment during dyeing finishing. The present inventors have found that it is possible to impart weft elongation and easy care properties without impairing the texture and physical properties of the cellulose fiber, and have reached the present invention.
That is, the configuration of the present invention is as follows.
[1] An unwoven fabric composed of cellulose fibers and warps composed of cellulose fibers and synthetic fibers, wherein the unwoven fabric is treated with epoxy-modified silicone during resin processing, and the following (1 A cellulosic union woven fabric satisfying the characteristics of (3) to (3).
(1) W & W property is 3.5 or higher (2) Stretch rate in the weft direction is 5% or higher (3) Hygroscopicity is 7.5% or higher

[2] The cellulose-based woven fabric according to [1], wherein the cellulose fiber is a regenerated cellulose fiber.
[3] The cellulose-based woven fabric according to [1] or [2], wherein the synthetic fiber is a polyester fiber.
[4] The cellulosic woven fabric according to the above [3], wherein the polyester fiber is a processed yarn of polytrimethylene terephthalate.
[5] The cellulosic interwoven fabric according to any one of [1] to [4], wherein a mixing ratio of the cellulose fibers is 70% or more.
[6] A cellulosic union lining comprising the cellulosic union fabric according to any one of [1] to [5] above.

  Since the cellulosic union woven fabric of the present invention has an appropriate stretch property, it has a high movement follow-up property when worn and is excellent in durability such as slipping. Moreover, since it is a woven fabric with a high cellulose mixing ratio, it is excellent in hygroscopicity and antistatic performance. Furthermore, it is excellent in W & W property and can provide a woven fabric having a high blending ratio of cellulose fibers having easy care properties that can be sufficiently washed with water at home, and in particular, a cellulose-based woven fabric lining having suitability for lining.

The present invention will be specifically described below.
The first structural feature of the present invention is a cross-woven fabric in which the warp is composed of cellulose fibers and the weft is composed of cellulose fibers and synthetic fibers, and the fabric is composed of a fabric that is treated with epoxy-modified silicone during resin processing. There is in point.
Among cellulosic woven fabrics, fabrics using cellulose fibers for either warp or weft and synthetic fibers for the other are generally known. For example, in plain fabric lining applications, most of these simple woven products are It is used. In the case of this simple union product, the mixing ratio of cellulose fibers is generally 40 to 60%. This unwoven product is characterized by the fact that the strength of the cellulose fiber is supplemented and the hue becomes chambray, but on the other hand, the texture becomes a synthetic fiber touch and the hygroscopic property is also halved, so the frictional voltage increases. However, it was not always excellent in wearing comfort.

In order to clear these drawbacks, it is necessary to increase the mixing ratio of cellulose fibers, but conversely, the water washing performance (which easily causes washing wrinkles), which is one of the objects of the present invention, decreases. Therefore, in the conventional concept, for example, in the case of a cellulosic interwoven fabric lining composed of cellulose fibers in either warp or weft and cellulose fibers and synthetic fibers on the other side, and a cellulose fiber mixture ratio of about 70% or more, Actually, it was considered difficult to combine the advantages of cellulose fibers with water washing performance.
However, as described above, in the present invention, it was discovered that the use of an epoxy-modified silicone in combination with finishing resin processing of a woven fabric significantly improves the washing performance of washing with less wrinkling and less texture change. This has led to overcoming difficult challenges. The greatest feature of the present invention is that this epoxy-modified silicone is used in combination to improve washing performance and texture durability.

The mixing ratio of the cellulose fibers in the woven fabric of the present invention is preferably 70% or more, more preferably 72% or more, and particularly preferably 80% or more. Although an upper limit is not specifically limited, It is preferable that it is 95% or less, More preferably, it is 90% or less.
The epoxy-modified silicone used at the time of resin processing in the present invention is a polymer having a number average molecular weight of 10,000 to 200,000 and means a dimethyl silicone derivative having an epoxy group which is a functional group that directly reacts with a hydroxyl group of cellulose. Epoxy groups include glycidyl type and alicyclic type, but any type may be used. These may be used alone or in a mixed system.
The concentration used is preferably in the range of 0.3 to 10% by weight, more preferably 0.5 to 5% by weight, although there is a balance with other resin processing agents. In the case of 0.3% by weight or less, wrinkles are likely to occur during washing and washing, and a desired washing performance cannot be obtained. On the other hand, when the amount is 10% by weight or more, the performance is satisfactorily satisfied, but it is not desirable because it is necessary to remove excess unreacted epoxy-modified silicone, which is wasteful in labor and agent cost.

As the catalyst for the epoxy-modified silicone, the catalyst for the non-hol type glyoxal resin described later can be used as it is. These may be used in a proportion of 10 to 30% by weight based on the epoxy-modified silicone. Further, a binder such as an aminosilane coupling agent may be used, and other softeners may be used in combination. The degree of epoxy modification (epoxy equivalent) should be selected in consideration of the efficiency of reaction with cellulose, but a commercially available epoxy equivalent having hundreds to thousands of epoxy equivalents is sufficient.
The effect of this epoxy-modified silicone on the texture hardening and washing wrinkles is that the epoxy-modified silicone has a large molecular weight, so it cannot penetrate into the inside of the cellulose fiber and reacts directly with the hydroxyl groups on the fiber surface, so that it is firmly fixed. It is inferred that the frictional resistance was reduced. Moreover, since it has many epoxy groups per molecule | numerator, if two or more of them react, it will play the role of bridge | crosslinking and it will be guessed that the form stability improved. It is presumed that this cross-linking action hardly causes texture hardening even when washing is repeated, or is reflected in wrinkle difficulty. For this reason, when the unwoven fabric constituting the present invention is not subjected to the epoxy-modified silicone treatment, the W & W property becomes 3.5 or lower, and the problem that the texture changes and becomes harder when washed is developed.

The cellulose fibers used for the warp and weft of the fabric of the present invention include regenerated cellulose fibers such as cupra ammonium rayon and viscose rayon, saponified acetate fibers, purified cellulosic fibers represented by lyocell, and spinning of these short fibers. Yarn is included. In addition, natural fibers represented by cotton and hemp are also included. Regenerated cellulose long fibers are preferred. If necessary, it may be twisted or mixed and used. A single yarn fineness of 0.5 to 5.5 dtex, 20 to 100 filaments, and a total fineness of about 30 to 167 dtex are preferably used. In the case of spun yarn, yarns 20 to 80 can be used. In some cases, silk or wool having high hygroscopicity may be blended with cellulose fibers and used.
As synthetic fibers used for the wefts of the woven fabric of the present invention, polyester fibers such as polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polylactic acid fibers, nylon 6, polyamide fibers represented by nylon 66, polyacrylonitrile fibers, Examples thereof include acetate fibers, polyurethane-containing yarns, and fibers made of the aforementioned synthetic resin copolymer. The total fineness of these fibers is 33 to 167 dtex, preferably 33 to 110 dtex, and the single yarn fineness is 0.5 to 10 dtex, preferably 1 to 5 dtex. These fibers can be used in the form of a composite yarn such as false twisting, twisted yarn, mixed fiber, covering, or the like, if necessary. Of course, a side-by-side type conjugate yarn is also included. As the yarn configuration in which the wefts are composed of cellulose fibers and synthetic fibers, the alternate use is preferable, but the ratio of cellulose fibers to synthetic fibers may be in the range of 3: 1 to 1: 3 depending on the yarn configuration (fineness).

In producing the unwoven fabric of the present invention, it can be woven under normal weaving conditions (weaving machine, weaving density, etc.). Examples of the fabric structure applied to the present invention include a plain structure, a twill structure, a satin structure, and a deformed structure thereof. The weaving density is in the range of warp density of 90 to 160 yarns / 吋 and weft density of 70 to 120 yarns / 吋, and may be appropriately selected according to the material and fineness of the yarn used. Basis weight of the fabric, but are not there is no problem as long as the range of 40 to 120 g / m ² particularly limited. A range of 40 to 90 g / m ² is particularly preferred as the backing. Typical examples of the method for weaving the union woven fabric of the present invention include ordinary looms, rapier looms, air jet looms, water jet looms, gripper looms, and multiphase looms, but are not limited thereto. .
The woven fabric of the present invention can be obtained by treating a woven raw machine by conventional refining, dyeing and finishing. For example, the refining can be performed using an open soap type continuous refining machine, a softener refining machine, a liquid flow type dyeing machine, a suspended in-bath type continuous refining machine, or the like. In addition, the dyeing process may be appropriately selected together with the dye according to the fabric configuration such as a cold pad batch method, a pad steam method, a pad roll method, a jigger method, a liquid dyeing method, a wins method, and a beam method.

Subsequent resin processing is not particularly limited as long as it is performed so as not to impair the shrinkage and fastness to wet friction of normal cellulosic fibers. In the present invention, the above-described epoxy-modified silicone may be used in combination at a desired concentration at the time of resin processing, and finished with a normal formulation. In addition to the resin processing agent, an antistatic agent, a water repellent agent, a softening agent, an antislip agent, an antiperspirant, an ultraviolet absorber, a photocatalyst, or the like may be added as necessary. Moreover, in order to improve the gloss, smoothness, texture, etc. of the fabric surface, a calendar process may be applied.
Examples of the resin processing agent other than the epoxy-modified silicone that can be used in the present invention include glyoxal resins, epoxy resins, urethane resins, ester resins, acrylic ester resins, and polycarboxylic acid resins. The catalyst may be appropriately determined depending on the combination with the resin, and an acidic catalyst or a latent acidic catalyst that is a catalyst for a glyoxal resin may be used. Examples of acidic catalysts include inorganic acids such as hydrochloric acid and sulfuric acid, organic acids, lactic acid, tartaric acid, citric acid, glycolic acid and other oxyacids, amine hydrochlorides, etc., and latent acidic catalysts include aluminum chloride and nitric acid. Examples thereof include inorganic metal salts such as aluminum, aluminum sulfate, zinc chloride, zinc nitrate, zinc borofluoride, magnesium chloride, and magnesium borofluoride.

The second feature of the structure of the present invention is that the cellulose-based interwoven fabric having a mixing ratio of cellulose fibers constituting the woven fabric of 72% or more has a W & W property of 3.5 or higher, a hygroscopicity of 7.5% or higher, The stretch rate in the weft direction satisfies all the conditions of 5% or more.
Only by satisfying all these conditions, it becomes a woven fabric that can be washed with home water and has excellent wearing comfort, but as far as the inventors know, there are those that satisfy two of these constituent requirements, There is no fabric that meets all these requirements.
First, although it is W & W property, the level that can be judged as being wearable without taking care of ironing etc. by looking at the fabric after washing is grade 3.5, and ironing is not done below grade 3.5 It is generally judged that it is a level that is not worried about wearing. In the present invention, a little synthetic fiber is inserted into the weft to reinforce the softness / easiness of deformation of the cellulose fiber, and it also reduces the deformation caused by washing by improving the lubricity accompanying the addition of epoxy-modified silicone. It is presumed that the W & W property higher than the grade could be expressed. The W & W property when the epoxy-modified silicone treatment is performed without inserting any synthetic fiber into the weft is 3.0 grade. Similarly, the W & W property when the epoxy-modified silicone treatment is not performed without inserting any synthetic fiber is 2.25 grade, W & W property when epoxy-modified silicone treatment is not performed even if a synthetic fiber is inserted is 3.2 grade, and it is confirmed that neither can satisfy the 3.5 grade of the present invention. is doing. That is, in the present invention, the yarn configuration of the unwoven fabric and the treatment with the epoxy-modified silicone are essential requirements, which contribute to the expression of hygroscopicity and stretchability described later.

  Next, hygroscopicity is mentioned as a characteristic of cellulose fiber. Here, hygroscopicity means the official moisture content in an environment of 65% RH at 20 ° C. This hygroscopicity is very important for cellulose fibers and leads to the characteristic of absorbing and discharging moisture (absorbing and releasing properties) according to the environment. For example, normally, cellulose fibers take in about 12% gaseous moisture in an atmosphere of 65% RH at 20 ° C., but when the environment changes to a humid environment such as 90% RH, the moisture content of gas around 25%. Can be imported. Therefore, the environment in the clothes, particularly the humidity in the clothes, can be lowered compared to a synthetic fiber that does not absorb and release moisture at all. In order to fully utilize these characteristics, it is considered that 7.5% or more is necessary as the hygroscopicity. In addition, the skirts in winter are manifested by static electricity, but hygroscopicity is an important factor here. Although the hygroscopicity of the cellulose fiber itself decreases when it is in a low-humidity environment, 7.5% or more is sufficient for the hygroscopicity of the fabric because it can take in moisture from the gas evaporated from the body when worn. It is done. From experience, it is not preferable that the hygroscopicity is 7.5% or less because the wearing comfort in the rainy season or summer is inferior and the antistatic performance is also lowered. On the other hand, the upper limit of hygroscopicity is about 12% maximum even when a 100% cellulose fiber woven fabric is not subjected to special chemical processing, and the upper limit of the woven fabric of the present invention can be basically considered to be 12%. However, for midsummer and rainy seasons, chemical processing that increases hygroscopicity may be applied.

  The next feature of the present invention is that the stretch rate in the weft direction is 5% or more. A recent survey of stretch rates for general clothing outerwear has shown that many are in the range of 8-10%. It is presumed that this is because the stretch of the skin during human movement is quite large, and even if the allowance is taken into account, there is a risk that wearing comfort may be impaired if the fabric does not have a stretch rate of about 8 to 10%. On the other hand, it has been empirically found that the stretch ratio of the lining is about half. The reason for this seems to be that the knots and seams correspond to the stretch of the outer material and are related to the shape retention of the outer material. Regarding the stretch, in the case of the outer material, it is possible to stretch to this extent because of the use of the span, but in the case of using the filament, it is difficult, and as far as the present inventors know, only the description of WO 99/31309 is known. However, in this patent document, there is no suggestion of the use of textile yarn or the use of epoxy-modified silicone that can be used for washing and washing at home.

Hereinafter, the present invention will be described more specifically with reference to examples, but the present invention is not limited to these examples. In the present invention, measurement methods, evaluation methods, and the like are as follows.
(1) Evaluation of Weft Stretch Rate Using KES-FB1 manufactured by Kato Tech Co., Ltd., a 20 cm × 20 cm woven fabric was stretched in the weft direction at a pulling speed of 0.2 mm / sec, and under a stress of 500 g / cm. Elongation E (%) was calculated by the following formula.
E (%) = (ΔL / L) × 100
Here, ΔL is the length (cm) stretched under a load of 500 g / cm, and L is the grip length of the fabric, which is 5 cm.
