[Industrial applications]

 The present invention is a curtain fabric formed by connecting net textures, more specifically, a flat knitted fabric with excellent dimensional stability in the weft and weft directions, good ventilation and transparent net knitting, and good shading / shielding properties. The present invention relates to a curtain fabric in which the thick portion is continuously knitted, and is suitable for curtain fabrics that are suspended around beds in hospitals, nursing homes, and recreation facilities.

[0002]

[Prior art]

 In large rooms such as hospitals, nursing homes, and other recreation facilities, many people, such as patients, the elderly, and guests, wake up in an array of beds, but a curtain is suspended between each person's bed. It is common to take measures to partition the surrounding areas and protect each person's privacy. In such a curtain, it is necessary to have a shielding property so that it cannot be seen by a person next to it, and a shielding property for shielding strong light, but on the other hand, it must have good ventilation to prevent suffocation. In addition, the water of the sprinkler can be sprayed when there is a misfire due to sleeping cigarettes, etc., and in hospitals, etc., there is also a fluoroscopic function that allows the nurses to easily see the state of the sleeping person (patient) during the night patrol. Requested.

[0003] Accordingly, in response to such a request, a sewn product obtained by stitching a thick cloth and a mesh net cloth has come to be used as a cloth for a curtain. Sewing with a full-blown net material has the drawback that it is difficult to sew automatically and the seams are easily unraveled.

The applicant of the present invention had previously conducted various trial researches in order to continuously knit a partition curtain material for large rooms such as hospitals by a warp knitting technique in view of the above-mentioned problems. In that case, it is difficult to knit with a needle of 18 gauge or less, and since the thick part of the obtained fabric does not have sufficient light-shielding properties, and the part of the net that can be knitted can only be knitted with the insertion structure, tear strength and tensile strength It was low, but productivity was poor due to the maximum number of formations.

Next, the applicant of the present invention tried to knit a thick warp knitted fabric having a net structure portion using a tricot warp knitting machine having a needle of 18 gauge or more. It is easy to expand and contract in the longitudinal direction and has poor dimensional stability, and there are only a few types of stitches such as diamond shape and hexagonal shape that can also knit the structural part that composes the net. The dimensional stability was poor.

[0006]

[Technical issues to be solved]

 The present invention was made in view of the above-mentioned drawbacks of the conventional curtain fabric having the net fabric portion, and has a transparent net knitted fabric portion and a good light-shielding / shielding property. A technical problem is to provide a curtain fabric that is a continuous continuous knitted fabric portion having a flat knitted fabric portion that is excellent in dimensional stability in the direction, and that is formed by coupling a practical curtain net knitted fabric portion.

[0007]

[Means adopted for solving the problem]

 Means adopted by the present inventor to solve the above technical problems will be described below with reference to the accompanying drawings.

That is, the present invention uses a warp knitting machine having a dense needle of 18 gauge or more, and the ground yarn Y ₁ is looped at a required pitch along each wale and is non-stretchable in the warp direction. Loop warp structure W and connecting ground yarn Y ₂ are looped to the ground yarn Y ₁ of the wale located at the outermost end and folded back to be formed by uniformly connecting the ground yarn Y _{1 of} each wale. A plain knit thick ground portion G formed by integrally knitting a non-stretchable loop weft structure C in the weft direction; and a ground yarn Y arranged in a predetermined width selected from the ground yarns Y forming the loop warp structure W in each course. The warp cord portion S _{1 in} which each loop is looped and a required course is knitted, and all or a part of the ground yarn Y that composes the warp cord portion S ₁ is formed by looping over two or more stitches. A net knitted fabric portion N formed by integrally knitting the weft cord portion S ₂ ; The point is that a continuous knitting means with a non-stretchable structure that warps a series of is adopted.
