Problems solved by technology

[0003] However, since the down comes from the feathers of geese and ducks, its main component is protein, and there is animal fat attached to the surface of the down, which is easy to get wet and breed bacteria during the long-term use of the down sleeping bag, which will not only reduce the quality of the down sleeping bag, but even endanger the quality of the down sleeping bag. People's health; at the same time, the waterproof and breathable performance of sleeping bags is also one of the factors considered when purchasing

Abstract

The invention discloses a highly waterproof antibacterial breathable sleeping bag and a preparation method thereof.The waterproof fabric is prepared by compounding bamboo charcoal fiber fabric, a polytetrafluoroethylene film and a hot melt adhesive, due to the existence of the polytetrafluoroethylene film, the fabric is excellent in waterproof and breathable performance, and the bamboo charcoal fiber fabric is good in antibacterial performance; therefore, by taking the waterproof fabric as a raw material, arranging the polytetrafluoroethylene film on the outer side, sewing the core sleeve and then filling the down feather filler into the core sleeve, the prepared sleeping bag is good in heat preservation performance and excellent in waterproof, antibacterial and air-permeable performance. The wool and a small amount of acrylic fibers are added, the fluffy feeling, the soft and comfortable feeling and the moisture resistance are improved, the surfaces of the wool and the acrylic fibers are treated through a stearic acid triethanolamine ester quaternary ammonium salt solution, and due to the charge attraction effect and the intermolecular hydrogen bond effect, the wool and the acrylic fibers are endowed with the high antibacterial property; the finally prepared sleeping bag has excellent antibacterial performance and good waterproof and moisture-proof performance, and is skin-friendly and comfortable.

Description

technical field [0001] The invention relates to the technical field of waterproof sleeping bags, in particular to a highly waterproof, antibacterial and breathable sleeping bag and a preparation method thereof. Background technique [0002] With the increase of people's outdoor activities, sleeping bags have become an essential equipment for outdoor camping. The existing sleeping bags on the market are generally filled with down or chemical fiber cotton to achieve the insulation effect of sleeping bags, and down sleeping bags have high warmth retention and elasticity. Well, it has high bulkiness, light weight and soft skin feeling, which is loved by people. [0003] However, since the down comes from the feathers of geese and ducks, its main component is protein, and there is animal fat attached to the surface of the down, which is easy to get wet and breed bacteria during the long-term use of the down sleeping bag, which will not only reduce the quality of the down sleeping...
