Compared with the prior art, the invention has the following beneficial effects:
1. based on the characteristic that the hot air non-woven fabric needs to use the bicomponent fiber, the invention realizes the preparation of different colored fibers by adding the color master batch into different layers (surface layers and/or core materials) of the sheath-core structure bicomponent fiber; when the non-woven fabric is prepared by utilizing core layer single-color fibers with various colors, the core layer fibers are only subjected to point bonding instead of regional bonding by controlling the temperature and the air quantity of hot air consolidation, so that the core layer single-color fibers can keep the original colors and do not generate color matching phenomenon, thereby preparing the multi-color hot air non-woven fabric.
2. According to the invention, the temperature and the air quantity of hot air consolidation are controlled, so that the surface layer single-color hot air non-woven fabric can realize regional adhesion rather than point adhesion during hot air consolidation, a non-woven fabric with a new color can be produced through a color mixing principle (the new color is obtained through color matching by adopting single-color surface layer double-component fibers, and is different from the original color of the adopted single-color surface layer double-component fibers after color matching, for example, the combination of green and red can generate yellow according to the color mixing principle, the combination of green and blue can generate cyan, red and blue can generate purple), and therefore, when raw material purchase and storage are carried out, hot air non-woven fabrics with various colors can be produced through the color mixing principle only by purchasing color bases of red, green and blue basic colors, the raw material types of a supply chain are simplified, and meanwhile, the material damage and the increase of the cost caused by frequent color replacement of the production line in the traditional technology are avoided.
3. According to the invention, the temperature and the air quantity of hot air consolidation are strictly controlled, so that the temperature and the air quantity are in a change trend of rising and then reducing, and the purposes of strictly controlling the bonding state of surface fibers and core fibers, enabling the color of the hot air non-woven fabric to be uniform and stable and avoiding color errors among batches are achieved.
4. When the hot air is solidified, the hot air temperature of the first section of oven is controlled to be 130-134 ℃, and the hot air temperature of the last section of oven is controlled to be 133-140 ℃; the maximum temperature in the middle of hot air consolidation is less than or equal to 142 ℃; the hot air volume of the first section of oven is 44-50%, the hot air volume of the last section of oven is 44-50%, and the maximum middle air volume of hot air consolidation is less than or equal to 59%; therefore, the prepared non-woven fabric has good performance, and the softness and wear-resistant grade reach the standard, and the color of the non-woven fabric is bright, uniform and stable.
Detailed Description
The present invention will be described in further detail with reference to examples.
Example 1
Taking a single-color non-woven fabric with a color on surface layer fibers and a purple coloring color as an example, a coloring process of hot air non-woven fabric is introduced, and the coloring process comprises the following steps:
step 1, selecting materials: PE is adopted as a surface layer material of the bicomponent fiber, and PET is adopted as a core material; the dosage of the surface layer material and the core layer material is 1:1;
step 2, preparing colored fiber yarn: according to the color requirement of the final product and the principle that the color of the surface layer is mixed according to the color mixing principle, but the color of the core layer is not mixed, the core layer color and the surface layer color of the colored bicomponent fiber are determined, and the color expression form of the needed colored bicomponent fiber is determined; then adding red masterbatch and blue masterbatch into the surface layer material according to the adding amount of 1.3%, taking the surface layer material added with the red masterbatch and the core material without the color masterbatch as raw materials, and carrying out melt spinning to ensure that the core material is completely wrapped by the surface layer material, thereby preparing the surface layer single-color bicomponent fiber with the red surface layer; taking a surface layer material added with blue masterbatch and a core material without the masterbatch as raw materials, and carrying out melt spinning to ensure that the core material is completely wrapped by the surface layer material, so as to prepare surface layer monocolor bicomponent fiber with a blue surface layer for standby;
Because the coloring color of the non-woven fabric prepared in the embodiment is on the surface layer fiber, the step needs to prepare the bicomponent fiber with the color on the surface layer, and the core layer is the natural color (white) of the fiber, and no color master batch is added; in addition, as the non-woven fabric of the embodiment is required to be purple, the purple is obtained by combining red and blue according to the color mixing principle, and therefore, the step is required to prepare surface layer single-color double-component fibers with red color and surface layer single-color double-component fibers with blue color;
step 3, opening, mixing and carding to form a net: according to the color requirement and the color mixing principle of the final product, selecting surface layer single-color double-component fibers with red and blue colors, then opening and mixing the surface layer single-color double-component fibers with the two colors according to the mass ratio of 1:1, and carding to form a net;
step 4, hot air consolidation: carrying out hot air consolidation on the carded fibers in a hot air oven to obtain colored hot air non-woven fabrics;
the hot air oven adopted in the embodiment is provided with 4 sections of ovens which are arranged in sequence, the carded fibers uniformly pass through the 4 sections of ovens, and the total time for passing through the 4 sections of ovens is controlled to be more than or equal to 0.06min;
setting the temperature of the first section of oven to be 133 ℃ and the air quantity to be 47%; setting the temperature of the second section of oven to be 141 ℃ and the air quantity to be 53%; setting the temperature of the third section of oven to be 141 ℃ and the air quantity to be 54%; setting the temperature of the fourth section of oven to be 138 ℃ and the air quantity to be 48%;
Under the above parameter setting of hot air consolidation, the surface layer fiber realizes 'regional bonding', the core fiber realizes 'point bonding', and after the red and blue colors of the surface layer fiber are uniformly fused together, the color is mixed into a new color purple, so the colored hot air non-woven fabric prepared by the embodiment is a purple colored hot air non-woven fabric with only a single color on the surface layer.
Example 2
Taking a prepared multi-color hot air non-woven fabric with colors being in a core layer and being in blue-green mixed colors (multi-color patterns of blue-green uniform mixed tiling) as an example, the coloring process of the hot air non-woven fabric is introduced, and comprises the following steps:
