Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a flannel-like knitted fabric, and more particularly to a flannel-like knitted fabric using filament mixed yarn, in which the hot-water fiber yarn is raised and at least a portion thereof is cut.

In general, knitted flannelettes include knitted fabrics with a double-sided structure using full wool yarn or woolen yarn, with both sides raised and curled.

This kind of flannel has a high density, so it has excellent heat retention, and has a moderate amount of tension and elasticity.Furthermore, it is brushed and vertically woven to the extent that the structure (knits) is not visible in appearance. However, in order to maintain the above characteristics and strength, especially tear strength, the fabric weight is increased (heavier).
As a result, it becomes thick and loses its lightweight feel, as well as its drape properties, pleat retention properties, and wrinkle resistance. On the other hand, in order to compensate for the above-mentioned drawbacks with knitted fabrics having a flannel effect, blended yarns of synthetic fibers such as polyester or acrylic and wool are used, but they have poor pilling resistance, lack tension and elasticity, and Problems remain, such as the lack of visibility of the twill, which is unique to Upper Furano, and the inability to sufficiently express the heathered appearance. The inventors
This method eliminates the various drawbacks of flannel-like knitted fabrics made from blended yarns, and also reduces the fabric weight, which is a drawback of regular flannel, and increases the lightweight feel while providing high heat retention, moderate tension, and waist feel. As a result of intensive research, we have developed a double-sided structure made using a specific blended yarn, with the aim of providing a flannel-like fabric that is thin, has excellent drape and pleat retention, and has sufficient tear strength. The inventors have found that a knitted fabric in which the moat yarn is raised and at least partially cut can achieve the above object, and have completed the present invention.

That is, the present invention consists of a fine fiber East A with a single yarn weave of 0.05 to 1.5 denier, a basic dye beamable polyester fiber East B, and a fiber East C with a single yarn weave of 0.5 to 5 denier, and Fiber East A and B are knitted fabrics with double-sided textures using on at least one side of the moat weave yarns that have been aligned and false twisted, and the kaji weave yarns are raised and at least partially cut. It is a flannel style knitted fabric.

First, the fishing line used in the present invention will be explained.

The mud woven yarn contains fine fibers A to A having a single yarn weave of 0.05 to 1.5 denier, preferably 0.1 to 1.0 denier, and various basic dyes of preferably 1.0 to 5.0 denier. Dyeable polyester fiber East B and single yarn weave 0.5-5. The fine fibers A consist of fibers of 0.5 to 3.0 denier, and the fine fibers A consist of fine-grade polyester fibers, or the joints of each component are separated. Preferably, the fibrillated composite fibers are fibrillated.
Fiber East C consists of fiber-forming polymer fibers such as polyamide, polyester, polyolefin, polyacrylonitrile polymer, polyvinyl polymer (e.g. polyvinyl chloride, polyvinylidene chloride), among others, polyamide or polyester fiber. The material is preferably made of polyester fibers. As the above-mentioned fibrillated composite fibers, fibrillated composite fibers made of multiple types of fiber-forming polymers with low mutual affinity are suitable. It is preferable that the components have a cross section in which the components are joined.Please give a specific example. A component with a cross section in which two components repeat side-by-side and are joined to form a hollow part as shown in the figure, a component with a radial shape as shown in FIGS. 3 to 6, and a component with a shape that complements the radiant part. A component with a cross section joined to other components, a component with a radial shape as shown in FIG. Examples include a V-shaped component that complements the concave portion, or a cross section in which the same component as the radial-shaped component is joined.

Among these composite fibers, the third one is easy to obtain filaments with a uniform cross-sectional shape during composite spinning.
It is preferable to have a radial-shaped segment in the cross section as shown in FIGS. The polymers forming the fibrillated composite fibers may be any combination of fiber-forming polymers with low mutual affinity, but polyamides,
A combination of two or more selected from the group consisting of polyester and polyolefin is desirable.

The polyamide referred to in this) includes nylon 6 and nylon 60.
Examples include aliphatic polyamides such as nylon 6 and 10, aromatic polyamides such as polyxylylene adivamide, and polyhexamethylene phthalamide. Examples of polyesters include polyethylene terephthalate, polyethylene isophthalate, copolymer polyethylene terephthalate, and polypropylene. Tylene terephthalate, etc., and polyolefins such as polyethylene and polyp. Examples include pyrene and polybutene-1, but the most desirable combination is polyamide and polyester, which cause few problems in processes such as composite spinning and stretching, which are easily fibrillated during false twisting, and which have good dyeability.
Use of such fibrillated conjugate fibers is preferable since it is possible to very easily give the knitted fabric the heathered texture unique to flannelette fabrics. By specifying the single yarn weave of the three types of fibers A, B, and C as described above, the fabric weight of the product (knitted fabric) can be reduced and the knitted fabric can have a high degree of heat retention and a flannel texture while increasing the lightweight feel. It is possible to provide a unique tension and stiffness based on the original effect of different woven yarn mud weaving, and also to create a mild heathered appearance based on the contrast of several color tones unique to flannel.

Further, in the present invention, since the fiber east B is made of polyester fiber dyeable with basic dyes, the mild heathered tone unique to the above-mentioned flannelette is extremely excellent. Furthermore, Textile East A
, B and C are expressed by the following formulas 1 and □ with respect to the weave of the blended yarn, respectively.

indicates the weave of the fibers A, B, and C, and D indicates the weave of the mixed twill yarn.

], the total density ratio of each fiber forming the mixed yarn and the weave of each single yarn will be balanced, and the above-mentioned lightweight feel of the knitted fabric will be increased and the heat retention and This is preferable because the features of the knitted fabric of the present invention, such as being able to maintain the original tension and stiffness of a flannelette and giving it an extremely flannel-like appearance, are particularly noticeable.

The dark twill yarn used in the present invention consists of the above three types of fibers
, B and C, and moreover, it consists of Fiber East A and Fiber East B.
(In this case, the threads may be tied in advance.)

) False twisting may be applied, and both fibers A and B may be interlaced and in a state of interlacing. Note that the interlace may be applied either before or after false twisting. Furthermore, when the above-described fibrillated conjugate fiber Higashi is used by undergoing the above-mentioned false twisting, the joints of each component of the conjugate fiber are separated and substantially fibrillated, resulting in fine fiber Higashi A. . The fiber east C is pulled together or combined or twisted together with the fiber east A and B to suppress the bulkiness of the fiber east A and B in the mixed state, and to improve the knitted fabric. By reducing the thickness of the fabric and improving its drape, pleat retention, and pilling resistance,
It gives knitted fabrics a suitable amount of tension, a sense of elasticity, and the unique flannel appearance, and the most effective method for imparting these characteristics is plying. In addition, the hot water shrinkage rate of Textile East C,
That is, for example, the shrinkage rate when treated with 98 oo hot water is:
It is preferable that the hot water shrinkage rate is higher than that of the false-twisted fiber east A and B, since bulkiness of the fiber east A and B can be further suppressed. When interlacing is applied as described above, the number of entangles representing the degree of entanglement of single filaments may normally be 10 to 120 times/m, but it may be 20 to 120 times/m.
60 times/m is preferred, particularly 30 to 50 times/m.

Further, when the fiber east A and B and the fiber east C are twisted together, the number of twists is preferably 50 to 400 T/m, and 100 to 30
More preferably, it is 0 T/m. The outer shape of the fibrillated composite fiber that can be used in the present invention may be circular or non-circular, and the single fibers constituting the fiber east B and C may be hollow fibers or irregularly shaped hollow fibers as necessary. Can be used.

The flannel-like knitted fabric of the present invention is a double-sided knitted fabric in which the blended yarn is used on at least one side, and the blended yarn is present on at least 30%, preferably at least 50%, of the surface where the blended yarn is present, and more preferably at least 50%. It is desirable for the appearance and feel of the knitted fabric that 65% or more of the fabric be made of the fishing fiber yarn.

Of course, the mixed yarn may be used on both sides of the knitted fabric. The fibers other than the moat yarn constituting the knitted fabric of the present invention are not particularly limited, but normal polyester or polyester false-twisted yarns are preferable.

The double-sided knitted fabric of the present invention includes Mocklodgea,
Examples include circular knitted fabrics such as double fleece and double pique, warp knitted fabrics such as half, back half, satin, back satin, inserted pile, and knitted pile.

The fabric weight of the knitted fabric is preferably 320 g/or less, preferably 290 g/or less.

If the basis weight is too large, it is not preferable because it becomes a thick knitted fabric and loses its lightweight feel, as well as the excellent drapability and pleat retention properties characteristic of knitted fabrics. The flannel-like knitted fabric of the present invention is obtained by raising at least one side of the knitted fabric and then usually shirring the fabric. Further, dyeing or sanding can be applied as necessary. Examples of the raising methods include loop raising and cut raising, but it is preferable to at least perform cut raising. In this way, a flannel knitted fabric having a double-sided weave using the blended yarn of the present invention on at least one side, and in which the blended yarn is raised and at least partially cut is obtained. still,
When an elastic polymer or a soft synthetic resin is attached to the structure of the knitted fabric of the present invention (the base material that supports the fluff below the surface fluff), it increases the fullness of the knitted fabric and makes the texture more flannel-like. It is preferable because it also improves pilling resistance.

Further, the amount of adhesion is preferably 0.1 to 1% by weight, preferably 1 to 7% by weight based on the weight of the knitted fabric. The step of applying the polymeric elastic material or soft synthetic resin may be carried out at any stage of the flannel type knitted fabric manufacturing process.

However, when napping or sanding is carried out in the manufacturing process, it is preferable to carry out the napping or sanding before the napping or sanding. Polymer elastomers include polyurethane, acrylonitrile-butadiene rubber, styrene-butadiene rubber, etc., and synthetic resins include polyamide, polyvinyl chloride, etc. Among them, polyurethane, especially water-soluble polyurethane, is the most practical. , Texture surface (soft).

) is also suitable. Therefore, according to the present invention, the material is thin and feels lightweight, has a high density and has excellent heat retention, has a moderate tension and waist feel, has excellent pilling resistance, and has no visible tissue in appearance. The result is a knitted fabric with a mild heathered texture unique to flannel.

Moreover, it goes without saying that such a knitted fabric has excellent strength, especially tear strength, which is not found in ordinary flannel or flannel products using blended yarns, considering the characteristics of the materials used.
Furthermore, the knitted fabric of the present invention has excellent drape properties, pleat retention properties, and excellent drape properties that are not found in ordinary flannelettes due to the unique effects of knitted fabrics.
It has wrinkle resistance, and has an extremely low washing shrinkage rate in terms of washing resistance, so there is no need to worry about it shrinking when washed like normal flannel, and it can be washed with water.

Further, from the viewpoint of the purpose of the present invention, it is preferable that the thickness of the knitted fabric of the present invention is about 0.6 to 1.1.

The knitted fabric of the present invention has a flannelette-like appearance and texture because the moat yarns are raised and at least a portion of the knitted fabric is cut.

Furthermore, the processed yarn was subjected to interlacing treatment to obtain a mixed fiber entangled processed yarn with an entangle number of 65/m. After that, the mixed woven entangled yarn and 3/13 fiber TOC made of polyethylene terephthalate and having a hot water shrinkage rate of 9.0% are combined and combusted at a twist number of 200 T/M to obtain a three-way mixed woven yarn. I got it. The thus obtained three-way dark twill yarn was supplied to the front part, and the polyethylene terephthalate of 3-12 was supplied to the back part.
A warp knitted fabric with a rudder 1/3 satin structure was obtained.

Next, the surface of the greige fabric was subjected to loop raising twice and cut raising six times, followed by relaxation treatment, and two-stage dyeing with basic dye and disperse dye.

After that, water-resistant urethane was impregnated and cured to a solid content of 4% by weight, and the surface was sanded and raised, then finished set with 15000 and shirred to give a fabric weight of 31 female. / Obtained 150 warp-knitted blankets from Ayanaka. The resulting warp-knitted fabric is relatively lightweight, has a texture that is difficult to obtain with ordinary raised fabrics made of polyester filaments, and has a moderate tension and waist feel, as well as a mild heather that is unique to Furano and has a moist feel to the touch. It had a textured appearance and also had excellent pleat retention and wrinkle resistance that cannot be obtained with ordinary wool flanno or wool-acrylic blend flanno.
