Definitions

  • the invention relates to an iron-on interlining nonwoven fabric, which consists of several layers of pile of pile and / or staple and / or continuous fibers arranged in parallel.
  • the layers are intrinsically and mutually exclusive with the help of binding fibers, e.g. bound by calendering.
  • An adhesive hot melt adhesive is patterned on at least one surface, e.g. in the form of dots.
  • Iron-on interlining nonwovens that are fiber-reinforced and e.g. Spot-welded hot-melt adhesive fibers as binding fibers are becoming increasingly important. They have a fabric-like character, are soft and drapable and therefore meet the modern line of interlinings in the clothing industry. Such interlining nonwovens are completely sufficient for many cases, but the resistance to dry cleaning and the abrasion of the very soft point-bound interlining nonwovens are in need of improvement. If the proportion of hot-melt adhesive fibers and the strength of the bond are increased, the abrasion and the resistance to dry cleaning are improved, but at the same time the hardness and rigidity of the nonwoven fabric increases undesirably.
  • the invention is based on the object of developing a particularly soft and nevertheless cleaning-resistant interlining nonwoven fabric which can also be used without complications for thin and soft modern fabrics and which nevertheless has the required resistance to dry cleaning.
  • the interlining nonwoven is intended to be used in men's and women's outerwear, especially for light and drapable fabrics.
  • the object according to the invention is achieved by the interlining nonwoven material reproduced in claim 1.
  • the sub-claims contain preferred designs.
  • the interlining nonwoven is therefore multilayered and is bound exclusively by hot-melt adhesive fibers as binding fibers. This affects both the floras themselves and among themselves.
  • the consolidation takes place e.g. by calendering with the help of heated smooth or structured calender rolls.
  • the top can also be coated with hot melt adhesive.
  • interlining nonwoven fabric With the interlining nonwoven fabric according to the invention, a fundamental improvement with regard to abrasion, dry cleaning and washing resistance of the stiffened textile fabric is achieved.
  • the interlining nonwoven fabric can also be used with very thin and soft outer fabrics that cannot be processed with conventional interlining fabrics.
  • Iron-on interlining nonwovens with the structure defined above are preferred, which contain an interrupted adhesive composition pattern and whose pile is laid crosswise. Only hot melt adhesive fibers in the specified proportions are used as binders. According to an expedient embodiment, only the uppermost pile layer contains hot-melt adhesive fibers in an amount of 30 to 60% by weight, based on the total weight of the fibers.
  • Bicomponent fibers made from polyethylene terephthalate / polybutylene terephthalate or from polyethylene terephthalate / copolyester are preferred as hot-melt adhesive fibers.
  • a bicomponent fiber made of nylon 66 / nylon 6 is also very suitable.
  • the multilayer structure is expediently constructed in such a way that 40 to 80% by weight, based on the total weight of the pile, consists of the pile layer or the pile layers with a lower proportion of hot melt adhesive.
  • an interlining nonwoven fabric made of several layers of fiber pile is already known, which is consolidated with a binder and which contains a preferably punctiform adhesive mass pattern.
  • this interlining nonwoven does not have the binder fiber distribution proposed according to the invention.
  • the known interlining nonwoven can likewise have different amounts of binder, these zones of different binder concentrations are arranged parallel to one another over the entire cross section of the nonwoven in the production direction.
  • the superimposed fiber pile are z. B. impregnated together with the binder, which is applied in different concentrations so that parallel tracks of different compositions are formed. In this way, for example, the shoulder or chest area of a jacket can be stiffened more than the lower edge of the garment.
  • Interlining nonwovens of various shapes have also become known from DE-A-25 50 253.
  • the problem according to the invention is not solved, since the known insert is a so-called “insert-plack combination”, which contains a conventional binder-fiber-bonded nonwoven with hot-melt adhesive fiber application and a shaping part called “Plack”. Both the insert and the plack are made of nonwoven and the combination is double-fixable and deformable with steam presses.
  • Such an insert is intended in particular for men's outerwear and does not affect the object of the invention.
  • the insert-plack combination replaces the previously sewn-in fabric combinations.
  • the interlining nonwoven fabric according to the invention consists of at least 2, but expediently at least 3 layers of pile, the proportion of binding fiber of which varies in the individual pile layers.
  • 2 pile layers only slightly, i.e. contain up to 30% by weight, based on the total weight of the hot-melt adhesive fibers, of binding fibers, it being possible for the pile layer facing the adhesive composition or both layers to be free of binding fibers.
  • These pile layers are just weakly bound and extremely soft.
  • this “underside” is not very resistant to dry cleaning, good ironing resistance is achieved after ironing onto the textile outer fabric.
  • the outward facing pile layer with one-sided adhesive mass sample application always contains the higher binder fiber content. This must contain at least 30% by weight of binding fibers, based on the total weight of the fibers of this pile layer. However, up to 100% binding fibers can also be contained in this layer. This results in a margin within the range of approximately 30 to 100% by weight.
  • the low-binder pile layers are very soft, they determine the overall character of the interlining nonwoven. Compared to a conventional multi-layer interlining nonwoven, e.g. According to DE-A-22 60 677, which contains an evenly distributed percentage of binding fibers over all 3 pile layers, completely new product properties result.
  • Suitable hot-melt adhesive fibers which have a lower melting point than the fibers to be bonded are suitable as binding fibers.
  • binding fibers there are good blends of Perlon @ mixed with polyester fibers or nylon 66 fibers.
  • Polyethylene terephthalate fibers are easy to bind with copolyester fibers.
  • bicomponent fibers are preferred, such as are commercially available, for example, as core sheath fibers made of nylon 6 / nylon 66. So-called side by side fibers are also well suited.
  • nylon 66 / nylon 6 bicomponent fibers preference is given to those made from polyethylene terephthalate / polybutylene terephthalate or polyethylene terephthalate / copolyester, it being possible for these fibers to be built up according to the core / sheath or side by side principle.
  • bicomponent fibers are also suitable, provided they are made up of two different melting components.
  • Suitable as co-fibers are all synthetic fibers with a higher melting point than the binding fibers, in particular polyamide 66 or polyethylene terephthalate. For some purposes it is desirable to mix cellulose, cotton or wool.
  • Crosswise or randomly laid nonwovens are preferred, although longitudinally oriented nonwovens can also be used or combinations of the two.
  • the multi-layer interlining nonwoven is coated with hot-melt adhesive.
  • the hot melt adhesive pattern can be adapted to the respective purpose. However, spot coating is preferred in most cases.
  • Suitable hotmelt adhesive compositions are conventional products, but in particular those made from terpolyamides with a melting range around 120 ° C., from copolyesters or low-pressure polyethylene. The adhesive must always be applied to the side that contains the lower proportion or no proportion of hot melt adhesive fibers.
  • the iron-on interlining nonwovens according to the invention are used in men's and women's outerwear and are suitable, for example, for light, soft and drapable fabrics. However, they can also be used especially in men's suits and women's costumes as well as in coats, wherever a soft, yet abrasion-resistant and very dry-cleaning-resistant insert is desired.
  • Nonwovens are carded on a system with 3 cards, the first card being laid with a fiber web with a fiber mixture consisting of 45% by weight, based on the total weight of the fibers, of a 3.3 dtex nylon 66 homophile fiber and 55% by weight of a bicomponent core jacket fiber (3.3 dtex) made of 50% nylon 66 and 50% nylon 6.
  • a fiber pile is laid on the other two cards, which consists of 10% by weight of the bicomponent core jacket fiber and 90% by weight of said 3.3 dtex nylon 66 homophile fiber.
  • the sheets are placed on top of each other with the help of a cross layer. The weight of each pile is the same and so high that the final weight of the bonded nonwoven is 60 g / m 2 .
  • the fleece is consolidated with a calender at 225 ° C, one of the steel rollers being smooth and the other engraved (0.55 x 0.8 x 0.65 mm dot dimensions, 30 dots / cm 2 , dot spacing in horizontal rows 2.1 mm, in vertical rows 1.6 mm).
  • the rollers are arranged that the fleece with the high proportion of the bicomponent fiber is in contact with the engraved roller.
  • the take-off speed is 10 m / min.
  • a hot-melt adhesive made of a terpolyamide nylon 66-nylon 6-nylon 12 with a melting point around 120 ° C. are applied in a dot form to the side consolidated with the smooth calender roll, which contains the smaller proportion of bicomponent fibers.
  • the interlining nonwoven fabric produced in this way has a soft, pleasant feel, textile case and an unusually good resistance to abrasion in the dry and wet state.
  • the interlining nonwoven is resistant to wet washing and dry cleaning. It is suitable as an iron-on interlining for outerwear of all kinds.
  • Example 2 On the same system as in Example 1 and in the same way, 3 piles with a homogeneous composition are carded. All fabrics contain 25% by weight of the specified bicomponent fiber and 75% nylon 66 with 3.3 dtex. The average fiber composition thus corresponds to that of Example 1.
  • the cross-laid nonwoven is consolidated as in Example 1 and then coated with 20 g / m 2 hot melt adhesive. The base material weight is again 60 g / m 2 .
  • the interlining nonwoven obtained has the same handle and textile case as the interlining nonwoven according to Example 1.
  • the resistance to dry and wet abrasion as well as to laundry and dry cleaning is considerably poorer. The difference becomes even clearer after 5 washes and 5 dry cleanings.
