AI Technical Summary

Problems solved by technology

On the one hand, the disadvantage here is that the availability of products with the necessary properties is still limited, for example, the melting point and viscosity of common spreading powders, and on the other hand, they are made from renewable raw materials compared to conventional products made from fossil raw materials products are typically significantly more expensive
Therefore, these products cannot be used for low-cost mass-produced items, such as clothing linings

Embodiment 1

[0054] The following adhesive compositions were prepared.

[0055] Composition of points under grid coat:

[0056] Polyelectrolyte composite composition 46.88% by weight.

[0057] (OC-Biobinder TM OAK-Organoclick-100% renewable raw materials:

[0058] Chitosan, Carboxymethyl Cellulose, Citric Acid, Water).

[0059] Modified starch (monophosphate modified) 15.62% by weight

[0060] (Aric 4574-Agrana->95% renewable raw material)

[0061] Vegetable Propylene Glycol 25.00% by weight

[0062] (Radianol 4710-Oleon-100% Renewable Raw Material)

[0063] Water 12.50%

[0064] Dynamic viscosity: 13Pas

[0065] Compositions for upper spots are used as dispersing powders:

[0066] Copolyamide (80-200 μm) (Platamid 2667 - Arkema - 60% by weight of renewable raw material) Ratio of upper / lower points: 5 / 5 by weight

[0067] Proportion of renewable raw materials in the total adhesive composition: 80%.

[0068] The adhesive composition was applied to a basis weight of 58 g / m 2 on ...

Embodiment 2

[0114] Coat 25 g / m with the paste spot composition of example 1 and conventional copolyamide powder (melting point 118-128°C - Schaettifix 5130) 2 PES nonwoven fabric

[0115] Adhesion:

[0116] Application weight: 10g / m 2 - Melting temperature: 127°C, 15s, 20N / cm 2 (Kannegiesser CV 1000 CF Tape Bonder)

[0117] Adhesion to 100% cotton test fabric (as shown in Example 1):

[0118] 5N / 5cm – non-woven fabric tear

[0119] Adhesion to 97 / 3 Wool / Elastane Test Fabric:

[0120] 5N / 5cm – non-woven fabric tear

[0121] Washing resistance:

[0122] Adhesion to 100% cotton test fabric after three washes at 40°C:

[0123] 5N / 5cm – non-woven fabric tear

[0124] Adhesion to 97 / 3 wool / elastic test fabric after three washes at 40°C:

[0125] 5N / 5cm – non-woven fabric tear

[0126] This example shows that the adhesion of the paste dots to the cotton test fabric was higher than the liner or the coated PES nonwoven fabric itself.

Embodiment 3

[0128] Coat 50 g / m with the paste spot composition of Example 1 and copolyamide powder (80-200 μm) 2 Organic cotton nonwoven fabric (Platamid 2667-Arkema-proportion of renewable raw materials 60% by weight)

[0129] Applied Weight: 13g / m 2 – Ratio of upper / lower point: 4 / 6 (weight) – Melting temperature: 150°C, 15s, 20N / cm 2 (Kannegiesser CV 1000CF Belt Bonder)

[0130] Proportion of renewable raw materials in the total adhesive composition: 75% by weight.

[0131] Adhesion to 100% Cotton Test Fabric (as in Example 1):

[0132] 15N / 5cm – non-woven fabric tear

[0133] Adhesion to 97 / 3% Wool / Elastane Test Fabric (as in Example 1):

[0134] 12N / 5cm – non-woven fabric tear

[0135] Washing Resistance:

[0136] Adhesion to 100% Cotton Test Fabric (as in Example 1) after three washes at 40°C:

[0137] 11N / 5cm – non-woven fabric tear

[0138] Adhesion to 97 / 3% wool / elastic test fabric after 3x40°C washes:

[0139] 12N / 5cm – non-woven fabric tear

Abstract

The invention relates to a hot-sealable textile sheet material having a support on the basis of a woven fabric, knitted fabric, optionally with weft insertion, or nonwoven fabric and an adhesive coating applied to the surface thereof, characterized in that 70-100% by weight of the adhesive coating consist of renewable raw materials.

Description

technical field [0001] The present invention relates to a heat-sealable textile sheet having a substrate based on a woven, knitted (optionally with weft inserted) or nonwoven fabric and an adhesive coating applied to its surface , and also relates to a method of producing the textile sheet. Background technique [0002] Linings are the invisible frames of various garments and have been known for a long time (cf. DE 10 2014000417 A1) and are also used to reinforce the front of garments or to reinforce collars and cuffs. These liners generally consist of a substrate, which may be in the form of a woven, knitted or even non-woven fabric, and an adhesive composition, usually thermoplastic, applied thereto, usually in the form of a grid, wherein when heat and pressure are applied, The adhesive composition provides good adhesion to garment fabrics. Common grids use 1-200 points / cm 2 , preferably, 20-150 dots / cm 2 . [0003] Such linings are designed to give shape and stabilit...
