Problems solved by technology

This multi-step working method is costly and does not yield satisfactory results
During care treatments - especially after chemical washing - flap flaps bonded to hot-melt-coated linings are often not sufficiently stable in shape
It loses its three-dimensional configuration during chemical washing, which is detrimental to the appearance and quality of the finished garment

example 1

[0046] At room temperature, 290 g (56% by weight of the total weight of the undried adhesive including all ingredients) is based on self-crosslinking styrene with a glass transition temperature of Tg = 2°C, a solids content of 60%, and slightly viscous - Aqueous dispersion of polymer of acrylate-copolymer added as viscose to 150 g of water. To this mixture, 1.5 g of melanin based on carbon black and 60 g (11.6% by weight of the total weight of the undried adhesive including all components) of copolyamide (melting temperature range from 90 to 160° C.) were added with stirring. hot melt adhesive. Subsequently, 15 g of a polyacrylate / acrylic acid copolymer were introduced as an aqueous dispersion with a solids content of 33% as thickener. After a stirring time of 30 minutes and a maturation period of 24 hours, the paste was embossed onto the carrier material by means of a squeegee through a perforated template (CP180, hole diameter 0.43 mm) by means of the paste pressing method ...

[0048] At room temperature, 290 g (56% by weight of the total weight of the undried adhesive including all ingredients) was based on carboxyl-modified A polymer emulsion of acrylic polymer was added as viscose to 150 g of water. To this mixture, 60 g (11.6% by weight of the total weight of the undried adhesive including all components) of hotmelt adhesive based on copolyamide (melting temperature range 90 to 160° C.) are added with stirring. 15 g of a polyacrylate / acrylic acid copolymer were introduced into the mixture as a thickener as an aqueous dispersion with a solids content of 33%. After a stirring time of 30 minutes and a maturation period of 24 hours, the paste was embossed onto the carrier material by means of a squeegee through a perforated template (CP180, hole diameter 0.43 mm) by means of the paste pressing method (rotary screen printing), The carrier material is thermally cured by PS method with 24g / m 2 A man-made fiber nonwoven by weight per unit area consisti...

[0050] At room temperature, 145 g (accounting for 50% by weight of the total weight of the undried adhesive including all ingredients) based on acrylate (with a glass transition temperature (DSC) of Tg = -43 ° C, a minimum film formation temperature of about 2 A man-made fiber non-woven fabric with a weight per unit area consisting of 65% polyamide fibers and 35% polyester fibers. The printed nonwovens were dried at 130° C. for 90 seconds in an air-circulating oven. The layer of adhesive after drying can reach 20g / m 2 .

Abstract

The invention relates to an adhesive compound for a hot-sealing insert, to an insert that is equipped with said adhesive compound, and to a method for fixing the insert. The adhesive compound consists of a thermoplastic hot-melt adhesive (A) that is not adhesive at room temperature and a pressure sensitive adhesive (B) that is adhesive at room temperature.

Description

technical field [0001] The present invention relates to an adhesive for a thermocompression bondable liner, a liner with the adhesive, and a method for joining the liners. Background technique [0002] Bondable fabric lining materials, also known as fusible interlinings or thermobonded interlinings, are used primarily in all types of garments and are used in garments to hold and / or stabilize fabric planar configurations such as fabric fabric. [0003] The fusible interlining is a fabric planar configuration, such as a textile, knit or non-woven fabric coated with a thermoplastic adhesive that can be bonded by thermocompression, the adhesive and another fabric planar configuration according to the influence of temperature, pressure and time, A cohesive and long-lasting bond with corresponding in-use firmness is achieved. Therefore, bonding to garments joined by a fusible interlining should withstand typical care treatments, daily laundry and chemical washes, and adhere effe...
