Embodiment 1

[0066] According to the double-point method known per se to have 100g / m 2 An areal density 100% polyester ("PES") nonwoven base fabric provides the coating. Here a paste with the addition of usual auxiliaries such as emulsifiers, thickeners and processing aids is used for the lower point. The paste comprises as polymer component HDPE having a melting point of 130° C. and an MFI value of 10 (g / 10 min, 190° C. under a load of 2.16 kg), applied with a melting point range of 145-155° C. and greater than 200 A polyurethane powder with an MFI value of (g / 10 min, 190° C. / load of 2.16 kg) was used as the spreading powder for the upper points.

[0067] During the coating process 12g of the under spot paste was applied and 25g of the spreading powder was laid down.

[0068] The interlining made in this way can be set at a temperature of 175°C with very good adhesion to various fabrics, and can withstand washing at 95°C.

[0069] After styling (175°C / 20s / 2bar-Gygli shirt press), the s...

Embodiment 2

[0073] Pretreatment of fabrics made of 100% cotton and for use with 130 g / m 2 It is equipped with a shirt interlining with a certain surface density, and it is coated by the double-point method. Here a paste with the addition of usual auxiliaries such as emulsifiers, thickeners and processing aids is used for the lower point. The paste contained as polymer component polypropylene having a melting point of 160° C. and an MFI value of 50 (g / 10 min at 190° C. and a load of 2.16 kg). Polypropylene with a melting point of 160° C. and an MFI value of more than 150 (g / 10 min at 190° C. and under a load of 2.16 kg) was applied as a spreading powder for the upper point. 10 g of under spot paste were applied during coating and 19 g of spreading powder were laid down.

[0074] The interlining made in this way can be set at a temperature of 180°C with very good adhesion to various fabrics, and can withstand washing at 95°C.

[0075] After styling (180°C / 20s / 2bar-Gygli shirt press), the...

Abstract

The invention concerns a textile fabric with a coating consisting of two layers of thermoplastic hot-seal adhesives of differing compositions applied one on top of the other, the second hot-seal adhesive, which is applied to the first, having a melting point of > 135 DEG C and a melt flow index (MFI) value of 50 to 250 g / 10 minutes (190 DEG C / 2,16 kg). The invention also concerns a method for producing a textile fabric comprising the following steps: a) producing a textile fabric using a textile fabric manufacturing technique; b) applying a layer of a first hot-seal adhesive to the textilefabric; and c) applying a layer of a second hot-seal adhesive to the textile fabric so as to d) form a layer of the second hot-seal adhesive over the layer of first hot-seal adhesive, the second hot-seal adhesive used having a melting point of > 135 DEG C and a melt flow index (MFI) value of 50 to 250 g / 10 minutes (190 DEG C / 2,16 kg). The textile fabrics can be used as interlining or lining material that can withstand stress during care treatment.

Description

technical field [0001] The invention relates to a textile planar structure which is particularly suitable as interlining (Einlage) material or lining (Futter) material It is characterized by improved application properties and improved processability, and also relates to the production of said textile flat structures and their use as textile interlinings. Background technique [0002] It is known to use various thermoplastic materials for backing fabrics or lining materials as adhesive medium for thermal bonding. Copolyamides, copolyesters and polyolefins are generally used here. [0003] Various methods are known from the prior art (Ansatz) for improving the processing and use properties of lining fabrics. [0004] For example, in US-A-3893883, a textile surface structure coated with a hot-melt adhesive (Schmelzkleber) is described, wherein a mixture of selected polyethylene and terpene resins is used as the hot-melt adhesive. mixture. [0005] In EP-A-110454, an inter...
