Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

Example one

This embodiment will be described in detail with reference to fig. 1 and 2. The novel silk-like cotton related to this embodiment includes base layer 1, and bottom layer 2 and moisture absorption layer 3 that set up in base layer 1's both sides.

The base layer 1 is made of superfine hollow polyester fibers, and the hollow polyester fibers are sequentially a hollow part 101, a first skin layer 102 and a second skin layer 103 from inside to outside. The ratio of the cross-sectional areas of the hollow portion 101, the first skin layer 102, and the second skin layer 103 is 1: 1: 1.

in the present embodiment, the first skin layer 102 is conventional polyester fiber; the second skin layer 103 is low-melting-point fiber. The low-melting point fiber is specifically PE or low-melting point polyester, and is selected to be low-melting point polyester in this embodiment. The low-melting-point fibers can enable the fibers of the base layer 1 to be bonded with each other when the base layer is subjected to hot air, so that the non-woven fabric with a certain thickness is formed.

In the present embodiment, the bottom layer 2 is a conventional polyester fiber layer. After the carded conventional polyester fibers are laid into a net, the polyester fibers are mutually consolidated in a glue-spraying cotton production mode to form a non-woven fabric.

In the present embodiment, the moisture absorption layer 3 is a polyacrylate fiber. The polyacrylate fiber has high moisture absorption performance.

Example two

A detailed description will be given of the novel silk-like floss according to the present embodiment with reference to fig. 3. The difference between the novel silk-like cotton related to the embodiment and the embodiment I is that: the bottom layer 2 in this embodiment comprises a parallel ply 21 and a cross ply 22. The arrangement can improve the net forming speed of the layer of polyester fiber and improve the production efficiency.

EXAMPLE III

This embodiment will be described in detail with reference to fig. 4. The novel silk-like cotton related to the embodiment is different from the second embodiment in that: the microporous membrane 4 is provided outside the moisture absorption layer 3 in this embodiment.
