Abstract

The method for making a tie comprises gluing a lining to the outer tie material and cutting it to shape. It is then sewn into a tubular shape, turned right side out and creases (13, 14) are ironed into its edges. An Independent claim is included for the tie.

Description

The invention relates to a method for producing a tie, in which A interlining is connected to a tie fabric by at least one the tie fabric is cut to size with at least two parts, the parts of the blank are sewn together by at least one cross seam the raw tie, i.e. the sewn parts, if necessary on both Tips are provided with lining parts, and by a longitudinal seam to one tubular tie is sewn together and the tie on right is turned and ironed and a corresponding tie with one an interlining fabric connected to a tie fabric with at least two parts of one Cut at least from the tie fabric, in which the parts of the cut sewn together by at least one transverse seam, if necessary at both tips of the sewn together parts with lining parts, and by a longitudinal seam are sewn together in a tube and ironed from the right.

Most of the ties on the market have a roughly the finished one The shape of the tie has an inlay attached to a longitudinal seam. Such a tie is made by first of the tie fabric at least two parts, usually two or three parts, one at an angle to the course of the thread Cut and from the interlining fabric an inlay whose shape is slightly smaller than that of the finished tie, and lining parts for the tips of the tie be tailored. Then the parts of the blank are made Tie fabric sewn together by at least one cross seam and on the ironed out the transverse seams on the left side. At the tips of the raw tie, i.e. the parts sewn together, the lining parts are sewn on the left side and ironed the tips if necessary. Then in a special Machine a longitudinal seam attached, in which the insert at the same time Longitudinal seam is attached. After turning the tie to the right side the tie is inserted into the tips of the tie after inserting a template ironed with steam if necessary.

The disadvantage of such a tie is that the insert, except for the attachment on the longitudinal seam, loosely located in the tubular tie. While washing The tie can warp and twist, causing it to become No longer a function of specifying the tie's stiffness and external shape can meet. The tie is without steaming again with suitable templates no longer usable. Such ties are therefore practically not washable but can only be dry cleaned.

To achieve a stronger hold of the tie fabric and to improve the smoothing effect of deposits is from the one registered in 1957 DE-U 1 747 008 known to connect the inserts firmly to the tie fabric. For this, the inserts can be placed on the uncut or the cut Tie fabric to be pinned. Furthermore, dating from 1971 registered DE-A 2 156 396 to achieve a particularly beautiful case known for cleaning a tie, tie fabric with a lining to be spot welded.

Both of the above methods of making a tie use a Interlining fabric with a tie fabric for improved portability of the tie. As far as the applicant is aware, according to this Processed ties did not come on the market. Cause for that could be that at the seams by possibly from tie fabric and interlining formed seam allowances problems have occurred.

DE-A 42 03 181 describes a generic method for producing a Tie, in which an interlining is combined with a tie fabric, and a generic tie known. In this procedure, a knitted Intermediate fabric in the same shape and dimensions as the Tie fabric cut and after sewing the two parts of the Tie fabric cutting and ironing the executed seam (cross seam) on the left side of the tie fabric fastened by heat. After sewing the middle seam (longitudinal seam) this is ironed out and fastened. That at this procedure is the execution of the seams specifically to the Manufacturing process adapted. Only tie fabric is used for the cross seam sewn together. Both seams are ironed out and fixed, the fixation the cross seam is made by attaching the interlining.

Such a manufacturing process for a tie has the difficulty that Attachment of the intermediate fabric to the left side of the tie fabric of the raw tie the intermediate fabric exactly on the sewn parts of the raw tie must be hung up. Through this and through ironing and fastening the middle seam is more expensive than a conventional one Production method. There is also washing one after this Process manufactured tie the risk that the intermediate material adheres to the Seam allowances of the ironed cross seam of the sewn together parts of the Tie fabric cut loosens. This can lead to the tie being worn repeated washing can no longer be brought into shape and thus theirs Dimensional stability loses.

In addition, from DE-C 30 39 878 in a method for producing lined ties made from an outer fabric blank and a lining fabric blank known to stick a tip reinforcement element on a carrier lining and with sew the two blanks.

The object of the invention is a generic method for producing a Develop a tie and a generic tie, the manufacture the tie simplified and the shape retention of the tie after the Washing is improved.

The object is solved by the features of claims 1 and 17. The Subclaims describe advantageous developments of the invention.

According to the invention in a method for producing a tie, in which an interlining is connected to a tie fabric, first one Composite made of tie fabric and interlining and from this the Cut to size with at least two parts.

In contrast to the generic method, the manufacturing step Cutting the interlining completely saved. Also the exact placement of the Insert blank on the raw tie, i.e. the sewn together parts of the Tie fabric cut, omitted.

The production of a composite before cutting can be done on a larger scale on a technical scale and thus carried out more cost-effectively and technically better are used as attaching a fabric blank to sewn together Part of a tie fabric cut with ironed cross seams. The Production of a composite material according to the invention essentially enables more durable connections between the tie fabric and the interlining than one Attaching an interlining blank to sewn-together parts of one Tie fabric placement.

Another advantage of using composite is that it is better than one Tie fabric can be processed. The production of the blank and the Seaming is easier because the composite is more resistant to sliding. The The strength of the seams is higher.

Surprisingly, a special execution of the seams is not necessary, i.e. neither ironing and fastening the transverse seams nor ironing and Fastening the longitudinal seam is required.

Creases with which the tie attaches to the materials of the composite adapted ironing conditions, ensure the dimensional stability of the Tie after washing. Ironing the washed tie is not more necessary. The creases extend along the edges of the tie over their entire length or at least almost over their entire length.

To produce the crease, the composite is deformed during ironing by compared to known ironing, for example in a flat ironing device, one or more of the sizes, temperature of the ironing device, internal pressure, Contact pressure and, preferably, the exposure time, is increased slightly. Will one like that manufactured tie, e.g. when washing, wrinkled, so find subsequently the tie is automatically reshaped into the shape fixed by ironing instead of.

The tendency of a composite to recover is due to the interlining much better than that of a tie fabric, since the crease recovery forces of the interlining fabric to that of the tie fabric. For the production Ties made of composite materials according to the invention are preferred interlinings used with a high crease recovery angle, resulting in a high Dimensional stability of the tie is achieved.

A tie manufactured according to a method according to the invention Claim 17 from a composite of washable tie fabric and washable interlining is washable without the interlining from Tie fabric loosens and without warping or twisting. The tie keeps its shape even after washing and is again without ironing usable.

When ironing steam can be used according to claim 2. Ironing with Steam, i.e. with the supply of heated steam, in itself is in the Known manufacture of ties. To create the crease in the composite When using steam, the steam temperature and Vapor pressure can be increased. By using steam, the ironing folds can more trained and / or the exposure time can be reduced.

The use of itself over the entire length or at least almost templates extending over the entire length of the tie according to claim 3 makes it possible to tie the ties with the appropriate ironing conditions To provide creases.

When laminating a tie fabric and an interlining fabric according to claim 4, the tie fabric and the interlining fabric are in the full range of the Tie fabric to a composite by gluing, needling, sewing, ultrasound or high-frequency welding connected together. Through the flat Laminated composites are particularly suitable for production washable ties.

When laminating a tie fabric and an interlining fabric with one Coating made of thermoplastic material according to claim 5, the both substances by heat and possibly pressure over a certain time Production of the composite glued together. This way of making the Composite is also called heat sealing or fixing. The bonding leads for a functional connection of the interlining on the tie fabric with a high separation resistance, which makes this composite suitable for washable ties further increased. The lamination parameters temperature, pressure and time are designed in such a way that little or no changes to the Occur on the surface of the tie fabric.

An interlining with a coating of grid-like, thermoplastic coating points according to claim 6, ie through spaced circular surfaces, for example with fine points with a diameter of about 0.3 to 0.5 mm, made of thermoplastic material, is particularly good for producing a Composite with a tie fabric suitable. In the case of a composite material in which the connection between the tie fabric and the interlining is made by means of grid-shaped, thermoplastic coating points, the look and feel of the tie fabric are retained. The tie fabric side is not, or at least not visibly, changed by the coating points attached to the left side (rear side) of the tie fabric, also called adhesive spots, since the choice of the diameter of the coating spots and the number of coating spots per cm ^{2 enables} an optimal adaptation to the tie fabric is possible. Points with a larger point diameter are arranged in a smaller grid and those with smaller point diameters are arranged in a larger grid.

The coating points can be in the form of microdots with more than 100 coating points per cm ² , for example in a grid of 25 or 30 mesh with 120 or 160 points per cm ² , and correspondingly small diameters, in the form of fine points with 50 to 100 coating points per cm ² , for example in a grid of 17 or 21 mesh with 52 or 76 points per cm ² , and diameters of for example approx. 0.5 or 0.3 mm or in the form of coarse points with 50 to 20 coating points per cm ² , for example in a grid of 15 or 11 with 35 or 22 points per cm ² , and correspondingly larger diameters. Micropoints are particularly well suited for coating the interlinings for very fine tie fabrics, fine dots for many of the common tie fabrics and coarse dots for example for coarse wool tie fabrics. The grid-like arrangement of the coating points can be designed as a linear arrangement or as a random arrangement. The coating points can be designed as simple powder points or preferably as paste points. Single points are used with closed interlinings, for example with dense fabrics, knitted fabrics or nonwovens.

Through the use of interlinings with two-layer coating points, i.e. with colons, according to claim 7, influencing the surface the tie fabric further reduced by the connection with the interlining. The colon coating of the interlining can be designed in such a way that on an inner, thin, thermosetting base layer, an outer, flat one sits thermoplastic layer, the outer layer after the Laminating process thanks to its delicacy the tie fabric side of the composite unaffected. Coating points designed as colons are especially for open interlinings, i.e. loose fabrics, knitted fabrics or fleeces suitable.

The outer thermoplastic layer can e.g. made of polyamide or copolyamide consist.

As mentioned, the inner base layer can be made of a thermosetting material or also from a thermoplastic material with a higher melting point or lower melt index than the thermoplastic material of the outer layer consist.

The base layer prevents thermoplastic material when laminating strikes back, i.e. that thermoplastic material through the interlining on the uncoated side of the interlining material flows and possibly other Treatments at higher temperatures or ironing processes for gluing, z. B. with lining parts leads. The tie fabric side retains, even with light ones Tie fabrics, the original structure of the surface of the tie fabric. The look and feel of the tie fabric are retained.

A method of making a colon coated Interlining is e.g. known from EP-B 0 731 151.

The usual tie fabrics, e.g. Jacquard are woven or printed and made of synthetic man-made fibers, such as Polyester, from cellulosic man-made fibers, such as viscose, from silk or from Mixtures of these materials with each other or with other native fibers, such as Wool or cotton are used.

The choice of interlining for a composite is of a type and type Depending on the severity of the tie fabric. It will also depend on what you want influences the external appearance of the tie. Is a rather voluminous looking tie is desired, so more voluminous, possibly heavier Interlinings used. If a rather delicate-looking tie is desired, then so lighter, flatter interlining fabrics are used. The following Examples 1 to 3 of composites described are for the preparation of a suitable for ties with little volume.

Insert materials made of synthetic are preferred according to claim 8 Man-made fibers, e.g. made of polyester, polyamide, polyacrylic or mixtures thereof, especially made of mixed fibers made of polyester and polyamide.

By using textured synthetic man-made fibers according to claim 9 the interlinings have a high elasticity and thus high Crease recovery angles and show strong self-smoothing effects that are reflected on transfer the composite. These interlinings enable the production of Ties with a particularly high dimensional stability, especially with a strong tendency to reform after deformations e.g. B. by binding, by Wash or in high humidity.

Fabrics with a basis weight of 40 to 120 g / m ² according to claim 10 can be used particularly well for the production of composite materials with all the usual tie fabrics, such as printing fabrics or jacquard fabrics, with a basis weight of 70 to 190 g / m ² .

For printed materials, e.g. B. with a basis weight of 80 g / m ² , heavier fabrics, for. B. with a basis weight of 70 to 100 g / m ² , in particular 80 to 90 g / m ² , are used as interlinings. For jacquard fabrics with a basis weight of 100 to 175 g / m ² , somewhat lighter fabrics, for example with a basis weight of 50 to 90 g / m ² , in particular of 70 g / m ² , can be used as interlinings. Tissue with z. B a plain, cross-twill and Panama weave are suitable for use with composites.

Fabrics, in particular those with a coating with colons according to claim 7, are particularly well suited for the production of composites with jacquard tie fabrics with launches that change in quick succession due to the good adhesion of these coated fabrics. Lighter fabrics, for example with a basis weight of 70 g / m ² , are used for this purpose.

To achieve a high elasticity of the tie, fabrics with textured, synthetic man-made fibers are used, the warp or weft threads textured, synthetic man-made fibers can exist. Preferably, the Warp and weft threads of the textured synthetic synthetic fibers, which makes the fabrics elastic in both directions, warp and weft are.

Fabric with textured weft and warp threads and with a weight ratio Warp / weft from 40/60 to 50/50 according to claim 11 lead to one in both Directions in approximately the same elasticity and thus to further increased Wrinkle recovery angles and an improved self-recovery effect. To cross-twill fabrics are preferred.

Interlining fabrics made of a fabric, the uncoated side of which 12 has a roughened surface can improve the grip of the tie make them appear more voluminous.

Elastic interlinings with a roughened surface are e.g. in DE-A 199 04 265 described; the roughening process is also called the peach skin process.

Knitted fabrics made of the above-mentioned synthetic, optionally textured chemical fibers, which are designed as warp knitted fabrics with weft insertion, Raschel knitted fabrics or knitted knitted fabrics, can be used as interlinings. The use of knitted fabrics according to claim 13 with a basis weight of 25 to 120 g / m ² enables less expensive composites and thus less expensive ties.

Warp knitted fabrics with weft insertion in open or closed leotard according to claim 14.

Nonwovens can be used as interlinings, with all nonwovens under the term nonwovens according to ISO 11224: 1993 are to be understood from the above synthetic, if necessary, textured chemical fibers can be used. The fleeces can be thermal be bound, i.e. be formed as a thermobond fleece. You can also use it as a Needle fleece can be formed.

The use of nonwovens with a basis weight of 25 to 90 g / m ² according to claim 15 enables particularly inexpensive composites and inexpensive ties made therefrom. Nonwovens are particularly well suited for the production of composites with heavy tie fabrics.

Water jet nonwovens are particularly suitable, in particular as pilling resistant designated water jet fleece, in which the formation of fine Fiber beads are suppressed by friction. Water jet fleeces stand out through good crease recovery values.

The advantages of the features of claims 18 to 19 correspond to those of Claims 3 to 16.

The invention is illustrated schematically in the drawing Example of a tie according to the invention and based on three material examples further explained.

In Figures 1 and 2 is a raw tie and a tie together with Templates shown, wherein Figure 1 is a longitudinal section through the tie above the templates and Figure 2 with a cross section through the tie Show template. Since the view in Figure 1 from above of the templates and the part of the tie that falls below is the part above the tie Longitudinal seam is not visible, it is dashed located. In FIG. 3, a cross section corresponding to FIG. 2 is without Template and in Figure 4 an enlarged section of the composite with a Colon shown.

In a method for producing a tie according to the invention, in which an interlining material is connected to a tie fabric, is first a Composite made of a tie fabric and an interlining.

Made of the composite with a tie fabric side A and an interlining fabric side B a cut obliquely to the thread course of the tie fabric of three parts 1, 2, 3 produced. The three parts 1, 2, 3 are made by two transverse seams 4, 5 sewn together and the sewn parts 1, 2, 3 on their two Tips 6, 7 on the interlining material side B of the composite with lining parts 8, 9 provided and by a longitudinal seam 10 to a tubular tie closed. The interlining material side B of the composite is on the outside. The The course of the transverse seams 4, 5 and the longitudinal seam 10 is shown in FIG dashed lines and the ends of the Lining parts 8, 9 shown by dotted lines.

Then the tie is turned to the right so that the Tie fabric side A of the composite is on the outside.

Before steaming, two will total over the entire length of the Tie-extending templates 11, 12 from both tips 6, 7 of the tie inserted. Then the tie is steamed so much that it turns on their two edges form creases 13, 14 over their entire length.

Steam is used for steaming. When used e.g. one flat Ironing device with steam addition is a temperature at the base of the device e.g. 150 ° C to 160 ° C, a vapor pressure of e.g. 5 bar leading to a Steam temperature of approx. 160 ° C, and an exposure time of e.g. 2 to 10 s, in particular from 4 to 5 s. The exposure time in this example is 1 to 2 s longer than with steaming without embossing of creases 13, 14 arise briefly in the crease 13, 14, i.e. on the edges of the tie, Temperatures of e.g. approx. 110 to 120 ° C. The exposure time becomes all the shorter selected, the higher the temperature and the higher the vapor pressure. The one there The pressure exerted corresponds to the pressure of when steaming ties 1.4 to 1.5 bar, e.g. 1.4 bar. The steaming conditions are based on the respective Composites matched.

The stencils 11, 12 are spaced a short distance apart into the Tie inserted. Alternatively, the templates 11, 12 can Touch steam in the tie.

For certain composites it is alternatively possible to cut vertically to use for the thread course of the tie fabric.

Alternatively, a cut from two parts or, in special cases, from more can be used as three parts.

Neither the transverse seams 4, 5 nor the longitudinal seam 10 are ironed out. alternative such ironing can take place. There may be other, usual steps, such as e.g. ironing the syringes 6, 7 provided with lining parts 8, 9, locking the longitudinal seam 10 or applying labels.

To produce a composite material, a tie fabric and an interlining fabric are laminated with a coating of thermoplastic material, that is to say they are connected over a large area. The coating has grid points on the interlining which are designed as colons, ie which consist of an inner thermosetting layer 15 located directly on the interlining and an outer thermoplastic layer 16 located thereon. In this example, the colons are designed as fine points. They can have a diameter of, for example 0.3 mm with a grid of 21 mesh, ie approx. 76 dots / cm ² , and of 0.5 mm with a grid 17 mesh, ie approx. 52 dots / cm ² .

When laminating, a tie fabric web is combined with one coated interlining certain lamination parameters, i.e. a increased temperature and pressure for a period of time, exposed, with the left side of the tie fabric on the coated side of the interlining. The fabric panels are, for example, with the help of a Print ribbon led around a printing roller. The pressure of the pressure roller is e.g. 2 bar. The external temperature is e.g. 130 ° to 140 ° C, resulting in a Joint temperature between tie and interlining of about 120 ° C leads. This treatment leads to a functional connection of the tie fabric with the interlining with a high separation resistance. The lamination parameters are designed in such a way that no or only slight changes on the surface of the Tie fabric occur.

For tie fabrics that are only exposed to temperatures below 100 ° C can be interlining with a coating that is used in a Glue joint temperature below 100 ° C, used.

A tie according to the invention has a blank made of a composite a tie fabric side A and an interlining fabric side B of three parts 1, 2, 3 on, the three parts 1, 2, 3 being sewn together by two transverse seams 4, 5 their tips 6, 7 are provided with lining parts 8, 9 and by a longitudinal seam 10 are closed to the tubular tie.

The tie has creases 13, 14 on its lateral edges.

The composite consists of a tie fabric and an interlining, whereby the left side of the tie fabric with an outer, thermoplastic layer of arranged on the interlining, arranged in a grid Coating points is connected. The coating points are as Colons with an additional to the outer, thermoplastic layer 16 existing inner thermosetting layer applied to the interlining 15 trained.
