Problems solved by technology

However, after the textiles treated with chemical reagents are washed several times, the one-way moisture transfer effect is easy to deteriorate, it is difficult to directly contact with the human body and use for a long time, and there is a problem of reagent pollution during the treatment process.

Embodiment 1

[0026] Select the viscose fiber with a fiber fineness of 1.5d and a fiber length of 38mm to be processed by acupuncture to a weight of 40g / m 2 Hydrophilic nonwoven batting layer 1. The cross-section polyester fiber with a fiber fineness of 1.68d and a fiber length of 38mm is selected and processed by acupuncture to a weight of 40g / m 2 Water-conducting nonwoven batting layer 2. Select polyester fibers with a fiber fineness of 3d and a fiber length of 64mm to be processed by acupuncture to a weight of 40g / m 2 Hydrophobic nonwoven batting layer 3. The specific preparation steps of the hydrophilic non-woven flake layer 1, the water-conducting non-woven flake layer 2 and the hydrophobic non-woven flake layer 3 are firstly to initially open the fibers through the coarse opener, and then pass them into the fine opener. The secondary opening is carried out, so that the large fiber clusters and blocks are torn into fiber bundles, and then the fiber bundles are combed into single fib...

Embodiment 2

[0028] Select bamboo fibers with a fiber fineness of 1.5d and a fiber length of 38mm to be processed by acupuncture to a grammage of 60g / m 2 Hydrophilic nonwoven batting layer 1. Select the Coolmax fiber with a fiber fineness of 1.68d and a fiber length of 38mm, which has a four-pipe hollow cross-section, and process it with a needle punching process so that the grammage is 50g / m 2 Water-conducting nonwoven batting layer 2. Select polyester fibers with a fiber fineness of 1.4d and a fiber length of 64mm to be processed by acupuncture to a weight of 50g / m 2 Hydrophobic nonwoven batting layer 3. Others are the same as embodiment one.

Embodiment 3

[0030] Select silk with a fiber fineness of 1.5d and a fiber length of 38mm to be processed by acupuncture to a weight of 60g / m 2 Hydrophilic nonwoven batting layer 1. Select Cooldry fiber with fiber fineness of 1.68d and fiber length of 38mm to be processed by needle punching process so that the grammage is 50g / m 2 Water-conducting nonwoven batting layer 2. The polypropylene fiber with a fiber fineness of 3d and a fiber length of 64mm is selected and processed by acupuncture to a weight of 30g / m 2 Hydrophobic nonwoven batting layer 3. Others are the same as embodiment one.

Abstract

The invention discloses a one-way moisture wicking needled composite multilayer wadding and a preparation method thereof. The one-way moisture wicking needled composite multilayer wadding comprises ahydrophilic nonwoven wadding layer, a water-conducting nonwoven wadding layer and a hydrophobic nonwoven wadding layer which are sequentially overlapped and are needled and compounded through a needling mechanism; fibers in the hydrophilic nonwoven wadding layer are hydrophilic fibers; fibers in the water-conducting nonwoven wadding layer are profiled-section hydrophobic fibers with micropores orgrooves; fibers in the hydrophobic nonwoven wadding layer are hydrophobic fibers; a plurality of tangling parts formed by fibers which extend out and entangle with each other along with the needling action of the needling mechanism are arranged between adjacent ones of the hydrophilic nonwoven wadding layer, the water-conducting nonwoven wadding layer and the hydrophobic nonwoven wadding layer; one-way moisture wicking is achieved by reasonably arranging the three layers of wadding with different water absorbing properties, a good damp-heat environment is maintained When a human body is in contact with the wadding, the wadding is suitable for direct contact with the human body, and the one-way wicking effect cannot be influenced by washing.

Description

【Technical field】 [0001] The invention relates to the technical field of wadding, in particular to the technical field of a unidirectional moisture-conducting needle-punched composite multi-layer wadding and a preparation method thereof. 【Background technique】 [0002] Flocks refer to sheet-shaped sponges made of plant fibers, animal fibers or chemical fibers for warmth, heat insulation or shock resistance. When traditional textile filling flakes are in contact with the human body, it is usually difficult to maintain the thermal and moisture comfort of the human body. The flakes made of chemical fibers have poor hygroscopicity, so the water vapor produced by the human body is not easily absorbed by the flakes, which easily makes people feel stuffy. It can absorb the water vapor produced by the human body, but because the binding force between the fiber macromolecules and the water is too strong, the water is easily stored in the flakes and is not easy to evaporate into the ...
