Embodiment 1

[0146] An embodiment of insulating material of the present invention is as follows:

[0147] Prepare a fiber mix by mixing the following materials:

[0148] -20%, 2.2 denier × 51MM low melting point binder fiber,

[0149] -60%, 2.0 denier × 51MM bicomponent self-adaptive fiber--nylon / polypropylene

[0150] -20%, 1.4 denier x 51MM siliconized fiber w / standard twist

[0151] After blending / fusion, the fiber mixture is processed into web form on a conventional card to form a nonwoven web. The web is then sent through a crosslapper to obtain the desired weight and thickness. The cross-lapped webbing is then thermally bonded and subsequently sprayed with a resin solution. Cut a C-shaped slit into the material, creating the flap. Such as figure 1 Final insulating material example shown.

Abstract

The invention provides insulation which comprises a plurality of reactive flaps that react to one or more external stimuli, e.g., humidity. The flaps are made up of a fiber mixture that includes: 20-80 wt % reactive bicomponent fibers that are reactive to an external stimulus, and have a first configuration in an unactivated state and a second configuration in an activated state, and wherein the bicomponent fibers can reversibly transform between the unactivated and activated states; 5-0 wt % synthetic binder fibers having a denier of 1.5 to 4.0 denier; 0-75 wt % of a first population of synthetic fibers, being synthetic polymeric fibers having a denier of less than 2.0 denier; and 0-75 wt % of a second population of synthetic fibers, being synthetic polymeric fibers having a denier of 4.0to 10.0 denier. Related articles and methods are also provided.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 62 / 448,182, filed January 19, 2017, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] The present invention generally relates to insulating materials, articles comprising said insulating materials and methods of making said insulating materials. Background technique [0004] People often find themselves in environments that can change rapidly. For example, people can quickly transition from a state of relative inactivity to a state of hyperactivity during exercise, or even while going about their daily activities. Likewise, people often move from controlled indoor climates to vastly different outdoor climates. In addition, climate change causes weather conditions to become unpredictable and vary significantly even during short periods of the day. Given that people regularly experience various humid...
