Embodiment 1

[0031] see figure 1 , a kind of polylactic acid fiber upright cotton material of the present embodiment, it is made by the polylactic acid fiber material of 100%, and the grammage of the upright cotton material of 1cm thickness is 40-60g / m 2 .

[0032] The polylactic acid fiber erecting cotton material of this embodiment includes an erecting cotton layer 3 in the middle, and the material of the erecting cotton layer 3 is polylactic acid fiber.

[0033] In some other embodiments, the upright cotton material also includes a first flat layer 1 above the upright cotton layer 3 and / or a second flat layer 2 below the upright cotton layer 3, such as figure 2 and image 3 . The material of the first flat layer 1 and the second flat layer 2 is also polylactic acid fiber.

[0034] Every 100g of polylactic acid fiber includes 20g-100g of two-component polylactic acid fiber, no more than 80g of single-component polylactic acid fiber and no more than 80g of three-dimensional polylacti...

Embodiment 2

[0058] The polylactic acid fiber erecting cotton material and its preparation method in this embodiment are basically the same as in the first embodiment, the difference is that all the polylactic acid erecting cotton materials in this embodiment are prepared from two-component polylactic acid fibers.

[0059] The two-component polylactic acid fiber in this embodiment: fineness 3.25dtex, average length 56mm.

Embodiment 3

[0061] The polylactic acid fiber upright cotton material and its preparation method in this embodiment are basically the same as in Example 1, the difference is that the polylactic acid upright cotton material in this embodiment consists of 20% by mass of two-component polylactic acid fibers and 80 The three-dimensional polylactic acid fibers of % mass parts are prepared, that is, 100g of polylactic acid upright cotton materials include 20g of two-component polylactic acid fibers and 80g of three-dimensional polylactic acid fibers.

[0062] Two-component polylactic acid fiber in this example: fineness 2.53dtex, average length 62mm, number of crimps 12 / 25mm; polylactic acid three-dimensional fiber: fineness 3.33dtex, average length 64mm, number of crimps 12 / 25mm.

Abstract

The invention discloses a polylactic acid fiber vertical cotton material. The vertical cotton material comprises a vertical cotton layer positioned in the middle, wherein the vertical cotton layer ismade of a polylactic acid fiber. According to the provided polylactic acid fiber vertical cotton material, the polylactic acid fiber is made into the vertical cotton material, so that the elasticity of a cotton sample is improved through a preparation process of vertical cotton while the characteristics of the polylactic acid fiber are kept, and the properties of a product are improved from all aspects. According to a preparation process of the polylactic acid fiber vertical cotton material, the polylactic acid fiber is prepared into the vertical cotton material according to a special raw material proportion and process parameters.

Description

technical field [0001] The invention relates to the technical field of nonwoven materials, in particular to a polylactic acid fiber upright cotton material and a preparation method thereof. Background technique [0002] As a new type of nonwoven material, erect cotton material has many advantages such as high elasticity, compression resistance, breathability and environmental protection, and has been widely used in people's daily life. [0003] Polylactic acid (PLA) is a new type of bio-based and renewable biodegradable material. It is made of starch raw materials proposed by renewable plant resources (such as corn). It has both the basic physical properties of synthetic fibers and natural fibers. biocompatibility and degradability. The biodegradability of polylactic acid fiber material is superior to other biodegradable fibers, and it has good hydrophilicity, curlability, dyeability, antibacterial and anti-mite properties, and UV resistance. The non-woven material made of...
