Abstract

The invention discloses novel heat preservation cotton for an outdoor exploration garment. The cotton is prepared from superfine glass fiber cotton and an acrylic resin adhesive with the mass ratio being (1.5-4):1. The average fiber diameter of the superfine glass fiber cotton is 0.1-0.8 micrometer, the number-average molar mass of the acrylic resin adhesive is 2,000-3,500 g / mol, and the acrylic resin adhesive evenly wraps the surface of the glass fiber to form an acrylic resin protection layer with the thickness being 20-150 micrometers; the superfine glass fiber cotton is distributed layer by layer, the layer thickness is 10-300 micrometers. The cotton has the advantages that due to the heat preservation cotton layered structure, the heat bridge effect of staple in the thickness direction is lowered, the heat conductivity coefficient is quite low, the heat preservation performance is excellent and the weight is low; the acrylic resin adhesive of the certain thickness evenly wraps the glass fiber, the strength of the heat preservation cotton is high, and the heat preservation cotton is not likely to be blocked or broken; the flame retardant property is excellent, the glass fiber overcomes the defect that a large amount of smoke is released during combustion of common cotton; the heat preservation cotton has the hydrophobic performance, the garment does not absorb sweat, and the breathability is good.

Description

technical field [0001] The invention relates to a thermal insulation cotton for clothing, in particular to a novel thermal insulation cotton for outdoor adventure clothing. Background technique [0002] Expedition clothing needs to adapt to extremely harsh environments, such as polar temperatures that are more than ten degrees below zero or even tens of degrees all the year round. Generally, cotton materials cannot meet the thermal insulation performance of this extreme cold weather. At present, there are two main types of thermal insulation materials for clothing. Types: One type is chemical fiber materials such as hot velvet flakes and acupuncture flakes; the other type is natural materials such as cotton, down, and silk. Natural materials keep warm and have good bulkiness, but they are not resistant to moths, easy to breed bacteria, strong hygroscopicity and easy to form blocks during use, making their thermal insulation poor; chemical fiber materials are relatively bulky...
