BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-sided raised knitted fabric for warp knitting.

[0002]

2. Description of the Related Art Conventionally, a double raschel machine having two rows of needle beds has been used for a product such as a warp knitted double-sided raised cloth, for example, a blanket. After knitting so that the napped yarn extends between the two fabrics, the napped yarn of the obtained knitted fabric is cut from the center, and the knitted fabric having the napped yarn only on one side is 2 One piece is obtained, and the surfaces of the two knitted fabrics where the napped yarn is not exposed are inwardly aligned and the edges are sewn together to obtain a product (blanket) in which the napped yarn is exposed on both sides. In the product thus obtained, the napped yarns stand almost uniformly perpendicularly to the ground structure, and although it has an excellent surface that is voluminous and has good pilling property, it is an accent on the surface of the knitted fabric. Therefore, unless the surface of the knitted fabric is changed monotonously by printing or the like, there is a problem that a product having a high commercial value cannot be obtained.

Various warp knitted fabrics are also manufactured by a knitting machine having a single-row needle bed. The knitted fabric thus manufactured is a single-sided knitted fabric with a sinker loop raised. However, although the outstanding features are recognized, there is a possibility that the napped yarn may be a raised fabric lacking a feeling of thin volume in which the napped yarn falls, and the pinging property is poor. Further, in order to deal with the above problems of the warp knitted napped cloth by this single-row needle bed knitting machine, the sinker loop is lengthened and knitted, and after dyeing, the tip of the sinker loop is cut and the thick knitted fabric is cut. Attempts have also been made to make the ground, but even in this way the napped yarn became almost uniformly perpendicular to the ground tissue,
The velvet-like knitted fabric only gives a knitted fabric lacking a proper sheep tone. As is clear from the above, a sufficiently satisfactory double-sided raised fabric has not been obtained in the past.

SUMMARY OF THE INVENTION An object of the present invention is to provide a double-sided fluffed cloth which is lightweight, rich in volume, has an appropriate sheave-shaped raised surface, and is excellent in high-class feeling and pilling property.

Means for Solving the Problems As a result of intensive studies to solve the above problems, the present inventors succeeded in obtaining a knitted fabric in which the above-mentioned problems of the conventional double-sided brushed fabric are solved. The present invention has been completed. That is, the present invention provides a crimped non-entangled portion of a lower napped yarn, which is formed by raising napped tissues on one side or both sides of the ground fabric at an angle of less than 90 ° with respect to the ground fabric, and a napped state of the upper napped yarn. It is a tricot double-sided raised cloth characterized by comprising an interlaced part.

Hereinafter, the present invention will be described in more detail. The napped cloth in the present invention is a napped cloth in which both the front and back sides of the knitted fabric are napped. The thickness of the napped cloth of the present invention may be arbitrarily selected, but is preferably at least 3.0 mm or more, and if the thickness is less than this, the napped cloth obtained lacks the voluminous feel, and the unit It is not desirable because it becomes inferior in heat retention efficiency per weight. In order to obtain such a preferable thickness and to obtain a double-sided raised cloth capable of achieving the object of the present invention, the density of the knitted fabric is set to 60 courses / inch or more and 30 wales / inch or more, which is relatively dense. A knitted fabric is preferable, and moreover, it is more preferable that the yarn constituting the raised fabric is formed of a multifilament yarn having a single yarn fineness of 2d or more.

Surprisingly, when a yarn having a single yarn fineness of less than 2d is used as the napped yarn, the napped yarn of the napped fabric is likely to fall down, and the double-sided woven fabric capable of maintaining the properties sufficient to achieve the object of the present invention. There is a greater chance that you will find it difficult to make a blanket. The double-sided raised fabric according to the present invention comprises a ground tissue and a napped tissue formed on both surfaces thereof. The napped tissue will be described below with reference to FIG. FIG. 1 schematically shows an example of a cross-sectional view of a double-sided raised cloth according to the present invention. C of FIG. 1 is a ground fabric of a raised fabric, and A, B and D are napped tissues. The napped tissue located on the surface of the ground tissue (C) is
The upper entangled portion (A) and the lower entangled portion (B) are used.

In order to achieve the object of the present invention, it is important to form a raised fabric having a raised fabric composed of such entangled parts and non-entangled parts on one side or both sides of the ground structure. The entangled portions (A and D) in the present invention are in a disordered state as illustrated in FIG. This fluffed state is obtained by disturbing the tips of most of the napped yarns so that the adjacent or adjacent yarns are entangled with each other.

On the other hand, the non-entangled portion (B) of the present invention
The napped yarns in (1) can be crimped gently without being entangled with each other even if the napped yarns are in contact with each other. The crimped shape of the napped yarn may be arbitrary, but it is preferable that the napped yarn has a "no" shape or a "ku" shape. The napped tissue forming the non-entangled portion according to the present invention is napped at an angle of less than 90 ° with respect to the ground tissue. If this angle is 90 °, the thickness of the napped cloth is maximum and a napped cloth with an excellent volume feeling can be obtained, but it becomes a hard napped cloth with a poor touch feeling, particularly inferior resilience, and a feeling of hard texture. Is not preferable.

The napped tissue of the non-entangled portion in the present invention is raised so that it is less than 90 ° with respect to the ground tissue, particularly preferably 60 to 85 °. By raising the hair in this manner, it is possible to obtain a raised cloth which is soft and rich in volume, and which is excellent in touch and repulsion. The tricot double-sided raised fabric of the present invention has a surface covered with a messy entangled portion in which napped yarns are entangled with each other, and the entangled portion occupies 10 to 40% in the thickness direction of the napped yarn on at least one surface. Things are preferred. When the thickness of the entangled entangled portion is more than 40%, the napped surface tends to be superior to the sheep shape, the quality is deteriorated, and the pilling property is deteriorated, which is not desirable. On the contrary, the thickness of the entangled part is 10%.
When the amount is less than the above, the raised surface is formed only in the portion which is hardly entangled, and the pilling property is good, but the high-class feeling, which is one of the most important factors as a product, is lost. On the other hand, the entangled portion is 1 in the thickness direction of the napped yarn.
The double-sided raised fabric, which accounts for 0 to 40%, is preferable because it can be a tricot double-sided raised fabric that has a high-grade sense as a product and is excellent in pilling property.

The thickness of the tricot double-sided raised cloth referred to in the present invention is A + B + C + D as illustrated in FIG. 1, and the entangled portion has a thickness A and the non-entangled portion has a thickness B. The ratio (%) occupied by is calculated by the following formula. In addition, the thickness of each portion in the present invention is a value obtained by using an enlarged cross-sectional photograph of the side surface (horizontal direction) of the tricot double-sided raised cloth. That is, the average position of the leading end of the napped yarn may be obtained as the thickness, and the thickness of the entangled portion and the non-entangled portion may be similarly obtained from the respective average positions.

The thread (ground thread) of the ground structure used for the tricot double-sided napped cloth of the present invention may be any thread such as polyester, nylon, polypropylene, cupra, rayon, cotton, hemp, wool and polyurethane. It may be used in any form such as twisted yarn and false twist. Further, it is preferable to use a multifilament yarn having a single yarn fineness of 2 to 5d as the napped yarn, and long fibers such as polyester, nylon, polypropylene, acrylic, cupra and rayon can be used. Further, as the ground yarn and the napped yarn, it is preferable to use a yarn having a thickness suitable for the gauge of the tricot knitting machine. For example, in a 28 gauge tricot knitting machine, a yarn having a total denier of 150 to 300 d is suitable. It is also possible to use the napped yarn thicker than the ground yarn.

Further, the tricot double-sided raised cloth according to the present invention is preferably a multifilament yarn having a single yarn fineness of 2-5d as mentioned above. When the single yarn fineness is less than 2d, the napped yarns of the napped fabric obtained tend to fall, and the thickness becomes thin, resulting in insufficient volume feeling, and a napped fabric with poor pilling properties is obtained, which is not preferable. Further, when the single yarn fineness of the napped yarn is thicker than 5d, the feel is hard, and it is not possible to obtain a product which is particularly satisfactory in touch feeling. Therefore, in the present invention, a multifilament yarn having a single yarn fineness of the napped yarn of 2 to 5d is preferably used, and by doing so, a tricot double-sided fluffed cloth which is rich in volume, excellent in pilling property and excellent in texture. You can get it.

Ordinary yarn is most suitable for the napped yarn used in the present invention, but if it is a false twisted yarn and the crimp elongation is 9% or less, a feeling of volume can be secured. It can be used because the decrease in pilling property is not so noticeable. The crimp extension ratio in the present invention is defined by JIS. Determined by L-1015. Next, a method for forming a napped tissue of the tricot double-sided raised cloth of the present invention will be described. First, for example, in a greige state after knitting, the needle cloth is caused to act from the knitting start direction of the sinker loop to nap. Then, the needle cloth is applied from the knitting end direction to raise the hair, and at this time, the sinker loop is completely raised so that the sinker loop is in a full cut state. After that, dyeing is performed by a jet dyeing machine, and a needle cloth is applied from the knitting start direction to raise the needle loop. Finally, the tricot double-sided raised fabric of the present invention can be manufactured by raising the sinker loop from the knitting start direction. At this time, the napped state before dyeing greatly affects the napped condition after dyeing, but by adjusting the napped state before napping so that the napped amount after dyeing is large, the thickness of the messy entangled part is increased. You can In addition, the raised hair after dyeing may use emery paper in addition to the needle cloth. Further, shirring is performed to adjust the thickness of the entangled entangled portion, and the entangled entangled portion is cut to reduce the thickness. You can adjust it.

Regarding the method of threading on the warp knitting machine when manufacturing the tricot double-sided raised cloth of the present invention, for example, the front reed and the back reed are polyester threads, and the middle reed is spun polyester thread. The front and back reeds are nylon, the middle reeds are cotton, the front reeds are polyester, and the middle reeds are wool.
The back reed thread may be formed by any method such as alternating one polyester thread and one cupra thread.

The tricot double-sided brushed cloth of the present invention absorbs moisture,
It may be a tricot double-sided brushed fabric with added value by imparting functionality such as water absorption, antibacterial, deodorant, quick-drying, and flame-retardant. As a method of applying the same, a pad dry method is used, or, for example, in the case of imparting water absorbency, a water absorbent fiber such as cotton yarn or cupra yarn is knitted to form a tricot double-sided raised fabric having water absorbency.

Further, in order to prevent the napped yarn of the tricot double-sided napped cloth from coming off, it is preferable to use spun yarn, processed yarn, yarn having a high boiling water shrinkage ratio, highly elastic yarn, etc. in the middle reed. By doing so, it is possible to obtain a raised cloth with less falling of the napped yarn. The tricot double-sided raised cloth of the present invention is preferably used for beddings such as boa sheets and blankets, and can be expected to be used for clothing such as winter clothes.
