Description

  The present invention relates to a curtain interlining attached along an upper end portion of a curtain and a curtain to which the curtain interlining is attached.

  The curtain has not only a function of blocking light but also a function as an interior decoration. In many cases, pleats are devised in order to give the viewer a sense of beauty and calmness.

For this reason, conventionally, a so-called tack knob for pinching and sewing, for example, each of a plurality of upper portions of a curtain body has been provided (for example, the column of the prior art in Patent Document 1, paragraph 0004, FIGS. 12 to 14). See). FIG. 12 shows a curtain provided with this type of tack knob. The step of the tack knob will be described with reference to FIG.
(A) First, the upper end of the curtain fabric to be the curtain main body 11 is folded, and the interlining 12 is inserted and sewn. (B) Next, the upper end of the curtain main body 11 including the interlining 12 is pinched to form a ring. The pair of bent portions 13 formed at this time are sewn together almost by the width of the interlining, (c) furthermore, the loop is folded inward, and this time sewing around the underground end of the core, and (d) the hook 14 is attached at the end. (E) Hang the hook 14 on a runner 16 slidably attached to the curtain rail 15.

  However, a curtain provided with such a tack knob requires a lot of man-hours, and therefore takes a long time to work, and also has a drawback that the finished product also has a wider hem and cannot obtain a desirable pleat shape. .

  Conventionally, as shown in FIG. 14, a gather tape 17 is attached to the upper portion of the curtain body 11, and two strings provided on the gather tape 17 are pulled to generate pleats in the curtain. There is. However, according to this, there is a disadvantage that the pleats are not formed evenly (also see the section of the prior art in Patent Document 1).

  Further, for example, a pleat is formed on the entire curtain body by subjecting it to steaming heat treatment, and a belt-shaped one is attached to the upper part of the pleat, and a hook is attached to the pleat. 0049, FIGS. 1-11). However, according to this, since a process of pleating the entire curtain body is essential, the operation is not easy, and there is a disadvantage that the required device becomes large.

  Conventionally, in the case of a curtain provided with a tack knob, in order to improve the drawback that the folds of the curtain spread, a band-shaped core material having a wavy shape is attached to a lower edge or an intermediate portion of the curtain fabric. (See Patent Document 2, specification, page 4, lines 8 to 14).

  However, according to this, in addition to the work of the tack knob, the work of attaching the belt-shaped core material is further required, so that there is a drawback that more man-hours and work time are required.

The band-shaped core material is a cloth made of thermoplastic synthetic fiber, a net or thin plate made of thermoplastic synthetic resin, or a metal plate (Patent Document 2, specification, page 3, line 11 to line 13). Therefore, it is insufficient as a core material to be attached to the curtain.
JP-A-9-10094 International Publication WO 02/19874 A1

  As described above, in the related art, there is a disadvantage that the operation requires a long time or that the operation is not easy, and further, there is a disadvantage that the shape of the pleat is not good. The present invention has been made in view of such conventional drawbacks, and an object of the present invention is to provide a curtain in which a manufacturing operation is easy and requires a short time, and a formed pleated shape is also favorable.

The invention according to claim 1 has a belt-shaped curtain interlining attached along the upper end of the curtain body, which has elasticity, and has a shape bent so that peaks and valleys appear alternately in the longitudinal direction. Have.
The invention according to claim 2 is a belt-shaped curtain interlining attached along the upper end portion of the curtain main body, comprising an interlining main body formed of a fiber material, and impregnating the interlining main body with a thermosetting resin. And then dried.
The invention according to claim 3 is the curtain interlining according to claim 2, wherein the fiber material is a polyester-based or nylon-based material.
The invention according to claim 4 is characterized in that the interlining body is a knitted product or a woven product.
The invention according to claim 5 is characterized in that the interlining body has a hook insertion bag portion.
The invention according to claim 6 is the curtain interlining according to any one of claims 2 to 5, wherein the curtain interlining is bent in a shape in which ridges and valleys alternately appear in a longitudinal direction. It is hardened.
The invention according to claim 7 is a curtain in which the curtain interlining according to claim 1 or 6 is attached along the upper end.

  According to the present invention, since there is no complicated and time-consuming work such as attaching a tack knob or gather tape, a curtain having pleats can be manufactured in a short time.

  For example, in the case of a tuck knob, in the case of a curtain having a width of 1 m, eight to nine places are tucked, but the time required for the operation is 180 to 210 seconds. However, it takes 120 to 140 seconds to sew the pleated interlining as in the present invention. In this way, the time required for sewing the upper part of the curtain is greatly reduced.

  Moreover, since the pleats according to the shape of the interlining are formed on the curtain body, pleats having substantially the same shape are formed in the vertical direction, and furthermore, the upper part of the curtain has no tack or gather tape, so it has a neat appearance. . For this reason, a curtain different from the conventional one can be obtained.

Further, the curtain according to the present invention can reduce the storage width as compared with the tack knob method. Because the curtain according to the present invention is pleated in the interlining, it is attached to the window, and when it is biased, it takes a little width compared to a curtain without such interlining. In the case of the tack knob, since the knob portion is thick, the width when the entire curtain is biased is a larger storage width than the curtain according to the present invention. Therefore, the curtain according to the present invention is a curtain in which pleats are generated when the curtain is unfolded. However, when the curtain is stored on one side of the window, the storage width can be reduced, and the light from the window can be widely taken into the room. it can.
Furthermore, since the body of the interlining is impregnated with thermosetting resin and dried, the shape of the interlining maintains the original shape even in normal use, and it is excellent in durability and of course, it loses shape due to washing. It is difficult to remove.

  FIG. 1 shows an external view of a curtain using the curtain interlining of the present invention as viewed from the back side. A band-shaped interlining 2 is sewn to the curtain body 1 along the upper end of the curtain body 1. The interlining 2 is elastic and band-shaped, and has a shape in which the valleys 3 and the peaks 4 are bent in the longitudinal direction so as to alternately appear, and resemble the cross section of the cigarette holder of the cigarette case. It is formed in a shape (hereinafter, referred to as a cigarette case type). That is, the interlining 2 has the bent portions and the curved portions formed alternately. On the back side near the bottom of each valley 3 of the interlining 2, a bag portion 5 is provided along the bottom. The hook 6 is inserted into the bag portion 5.

Next, a method for manufacturing such a curtain will be described.
(1) Manufacture of interlining: As shown in FIG. 2, the interlining body 2a is formed by knitting a polyester-based yarn into a belt shape. This interlining body 2a is impregnated with a thermosetting resin and then dried. The interlining body 2a in this example has double-knitted portions at predetermined intervals as shown in FIG. The double knitted portion has an opening 5a at the lower end, and forms the bag portion 5 into which the insertion portion of the hook 6 is inserted.

Here, as the thermosetting resin, for example, a mixed solution having the following combination is used. The solvent of each solution is water, and these resins are dispersed in water.
(a) 7% solution of self-emulsifying polyester resin, 2% solution of melamine resin
(b) 5% solution of self-emulsifying polyester resin, 1% solution of blocked isocyanate-based crosslinking agent (c) 6% solution of self-emulsifying polyester resin, 2% solution of phenol resin
(d) Self-emulsifying polyester resin 7% solution, urea resin 2% solution
(e) Acrylic copolymer aqueous emulsion 7% solution, silicone resin 0.5% solution, urethane polymer 3% solution

  In each case, the interlining is impregnated with the mixed solution of the resin and dried. The method of impregnation and drying is described in detail.

  Here, an apparatus as shown in FIG. 15 is used. The apparatus includes a container 30 containing the mixed solution, a roller 31 for immersing the band-shaped member serving as the interlining body in the mixed solution, a squeezer 32 including a pair of rubber rollers, and a dryer. 33 are provided. In this apparatus, the band-shaped member serving as the interlining body is passed under the roller 31 so as to be sandwiched between a pair of rollers by the squeezing device 32, and then disposed so as to pass through the dryer 33. Then, the belt-shaped member is pulled from the outlet side of the dryer 33. In this way, the belt-shaped member is first immersed in the mixed solution of the thermosetting resin contained in the container 30 and then squeezed from both sides by the squeezer 32 to be uniformly coated. The above impregnation process is performed at normal temperature (15 to 20 ° C.). Next, the belt-shaped member is dried at 100 to 110 ° C. for 1 minute by the dryer 33. Thus, the belt-shaped member is continuously processed, impregnated with the thermosetting resin, and dried. Next, the strip-shaped member is cut to a desired length to complete the interlining.

  (2) Pleating of interlining: Next, the interlining 2 containing a thermosetting resin is subjected to pleating. Here, as shown in FIG. 3, a cigarette case type pleat is formed. The pleating process will be described as follows. First, a pair of kraft papers (patterns) formed in the same pleated shape are prepared, the interlining 2 is sandwiched between them, and then the pleats are fixed in a state where the pleats are brought closer to each other. After steaming and cooling, it is removed from the paper pattern. Here, steaming heat treatment conditions of 100 ° C. to 120 ° C. for 15 minutes to 30 minutes are appropriate. As shown in the plan view of FIG. 4 (a) and the side view of FIG. 4 (b), the interlining with the cigarette case-type pleats formed on the back side near the bottom of the valley 3 of each pleat is illustrated in FIG. The bag part 5 shown in FIG. The width of the interlining 2 is about 10 cm (8 to 12 cm), and the width of each pleat is about 10 to 25 cm.

Here, the pleated retention of the pleated interlining impregnated and cured with the thermosetting resin of the specific examples (a) to (e) described in paragraph 018 and the pleated interlining not containing the thermosetting resin Table 1 shows the differences.
Note that the original interlining is common to polyester interlining having the same knitting structure.

  Here, the test method of the pleat retention is performed by an immersion method determined by The Woolmark Company, which is well known in the pleat industry. That is, after immersion in 70 ° C. warm water containing 0.2% of a nonionic surfactant for 30 minutes, dehydration and drying. After drying, the degree of opening of the pleats is determined.

For reference, a photograph of the criterion (manufactured by The Woolmark Company) is shown in FIG. A pass is judged to be a grade 3-4 or higher (grade 3-4 is on the pass / fail line).
Class 5 --- The folds before and after immersion are exactly the same.
Grade 4 --- The crease peak is lower than before immersion.
Class 3 --- The fold peak disappears, and only the line remains.
Class 2 --- A slight fold line remains.
Class 1 --- The fold completely disappeared.

  This test method has an experimental value that is comparable to the pleat retention after repeated washing 30 times at room temperature (usually 20 ° C. or lower) in a home washing machine. In general, the retention of pleated curtains after two years of use is much better than the retention of 30 repeated washes.

  As shown in Table 1, according to the interlinings impregnated with the thermosetting resins of the above specific examples (a) to (e), all the test results were grade 4 or higher, and the pleat durability was excellent.

  (3) Attaching the interlining: Next, the pleated interlining 2 is cut to a required length, and is sewn to the curtain main body along the upper end portion of the curtain main body while being stretched linearly. The sewing method will be described. As shown in FIG. 5, after a predetermined length of the upper part of the curtain cloth to be the curtain body 1 is folded, the interlining 2 is placed on the outer surface of the folded portion, and Are sewn to the curtain body 1 together with the folded portions. 5A is a plan view, and FIG. 5B is a side view. Here, as shown in FIG. 1, the interlining 2 is sewn such that the valley 3 formed by the bent portion of the pleat is on the opposite side (outside) of the curtain body 1.

(4) Attachment of Hook: Next, as shown in FIG. 6, the insertion portion 6a of the hook 6 is inserted into the bag portion 5 of the interlining 2, and the hook 6 is attached to the interlining 2. The curtain hook 6 formed as described above is hung on the runner 8 of the curtain rail 7.
Thus, the curtain of the present invention is hung on the curtain rail 7.

  As a most suitable example when using the curtain, the elasticity of the interlining 2 is determined by the shape of the interlining 2 formed at that time when the curtain main body 1 is spread and there is no horizontal force. When pleats 1 are formed and the curtain main body 1 is shifted, the spread is slightly larger than the case where the interlining 2 is not provided, but the spread does not change much as it looks.

  According to the curtain of the present embodiment, a cigarette case-type pleat is formed in the curtain body 1. Further, since the interlining 2 is attached to the outside of the folded back portion of the curtain fabric and the bag 5 for hooking is provided, the attaching work of the hook 6 is extremely simple. The bag portion 5 is knitted together with the interlining body 2a when the interlining body 2a is manufactured, and is integrally manufactured as shown in FIG. Therefore, the interlining body 2a with the bag portion itself can be easily manufactured.

  The bag portions 5 formed on the interlining body 2a as described above are arranged one by one near each valley portion 3 of the pleats. However, as shown in FIG. If the interlining body 2a in which a large number of the pleats 5 are arranged is manufactured, the hook 6 can be mounted at an appropriate position, regardless of how the interval between the peak and the valley of the pleat is determined.

  In the above example, the interlining 2 is sewn on the outside of the folded portion of the curtain body 1, but as shown in FIG. 8, the interlining 2 may be sewn on the inside of the folded portion of the curtain body 1. . However, in this case, the hook attached to the curtain body 1 uses a snap-type hook 9 composed of a male part 9a and a female part 9b as shown in FIG. This is penetrated and attached to the upper part of the curtain main body 1 as shown in FIG. Of course, in the case of such a configuration, it is not necessary to provide a bag portion in the interlining. FIG. 9C is a view as seen from the front side of the curtain, and FIG. 9D is a view as seen from obliquely above the back side of the curtain.

  Instead of a curtain rail, a runner and a hook, as shown in FIG. 10, an overhead wire 20 and a wire with a slidable clip 21 are used, so that the upper part of the curtain is picked up and suspended. You may do it. In this case, since the structure for attaching the hook to the curtain body 1 is unnecessary, the structure of the curtain itself is simplified.

  In the above description, the interlining 2 is provided with cigarette case-type pleats. This may be a so-called corrugated type as shown in FIG. 11A or a mutual type as shown in FIG. A so-called shell type in which the tip of the peak and the bottom of the valley are widened, or a so-called accordion type in which both the peak and the valley are bent as shown in FIG. Also in these, similarly to the cigarette case type described above, the interlining width is about 10 cm (8 to 12 cm), and the width of each pleat is about 10 to 25 cm.

  Further, in the above example, the interlining body was formed using a polyester material, but this may be a thermoplastic material, and may be formed using, for example, a nylon material. The reason why the interlining body is made of a thermoplastic material is that shaping (shaping into a cigarette type, shell type, or the like) can be easily performed.

  Further, the interlining body may be a woven product instead of a knitted product. In any case, the following effects can be obtained by impregnating the above-mentioned thermoplastic interlining body with a thermosetting resin, drying, and then heat-treating the main body into a predetermined shape and shaping.

  When shaping is performed on the interlining formed without performing the above-described treatment with the thermosetting resin and provided on the upper part of the curtain, the shape of the upper part of the curtain loses its own weight below it and is easily collapsed. However, the interlining formed by performing the above-described treatment with a thermosetting resin, when subjected to shaping by heat, since the interlining body is thermoplastic, the shaping is easily performed, Since it contains a thermosetting resin, the shape after shaping is firm, and the shape is well maintained. For this reason, when such an interlining is provided on the upper part of the curtain, it does not lose its own weight of the curtain below it and does not collapse, thereby preventing collapse of the shape of the entire curtain. Therefore, such interlinings are optimal for pleats in curtains.

  Further, in the above example, the curtain body itself is not pleated, but pleats corresponding to the pleat shape of the interlining may be applied to the curtain body and attached to the interlining. This provides a curtain with more pronounced pleats.
