Description
Technical Field
The invention belongs to the field of textile material processing, and relates to a preparation method of a spun-bonded non-woven fabric, in particular to a double-component self-crimping high-fluffiness fiber spun-bonded non-woven fabric and a preparation method thereof.
Background
The spun-bonded non-woven fabric in the prior art is widely applied to the fields of baby diapers, adult sanitary products, medical clothing, filtering materials and the like due to short process flow, high yield and good mechanical properties of products. With the increasing living standard of people, the requirements on the performance of non-woven fabrics, such as softness, bulkiness, strength and adsorption performance, are higher and higher. The hot air non-woven fabric is prepared by mechanically crimping short fibers and penetrating hot air on drying equipment through a fiber web to be heated to realize bonding and fluffing, but the process route is long, the mechanical property of the product is poor, and the high-demand application of the product cannot be met.
The Chinese patent application with the application number of 201410023549.2 discloses a double-component coarse denier spunbonded filament non-woven fabric. The skin-core composite spinning is used for preparing a two-component non-woven fabric material which has no surface prickling points, large air permeability and is fluffy, but the unit mass of the non-woven fabric is heavier, and the thickness of the fabric is increased to a certain extent due to the fact that the fluffy degree is improved;
the Chinese patent application with the application number of 201811016920.7 discloses a preparation method of high-bulkiness non-woven fabric. The raw materials used are PP and PE, and a nonionic surfactant and a nucleating agent are added into one of the components, and the high crimp of the fiber is caused by utilizing the different crystallization temperatures and crystallization speeds of the two components, so that the high-loftiness non-woven fabric is prepared, but the preparation method related to the patent has the advantages that because the crystallization speeds of the PP and the PE are higher, the space which can be improved by increasing the difference of the crystallization speeds of the components by adding the nucleating agent is smaller, so that the crimp rate of the material is lower;
the Chinese patent application with the application number of 201811415911.5 discloses a double-component crimped spun-bonded filament non-woven fabric, crimped spun-bonded filaments are obtained by adopting a parallel composite spinning method, then the spun-bonded filaments are bonded by hot air to prepare spun-bonded non-woven fabric, and the potential crimping potential energy of the double-component fibers directly prepared by a spinneret plate can not be completely released without any heat treatment process, so that the formed crimped fibers have low crimping rate and unstable structures;
the application number of 201820020878.5 of the Chinese utility model discloses a high-fluffy super-soft parallel double-component spunbonded nonwoven production line.
Said invention patent utilizes the difference of shrinkage stress of two components to make the fibre be bent toward one side and at the same time the fibre be twisted along the axial direction so as to form natural crimp of fibre and can be used for preparing fluffy non-woven fabric.

EXAMPLE 163 comparison of the Properties of a two-component self-crimped high loft fiber spunbond nonwoven
In this embodiment, the copolyesters used for preparing the spunbonded nonwoven fabric by using the conventional spunbonded nonwoven fabric preparation process are the copolyesters prepared in embodiments 1 to 6, respectively, and are sliced, dried, fed, melt-extruded and spun, and then are subjected to drawing, splitting and lapping after cooling, and finally the fiber web is reinforced, so that the conventional spunbonded nonwoven fabrics C1 to C6 are obtained.
It should be noted that the performances of the two-component self-crimped high-loft fiber spunbonded nonwovens B7-B162 in the embodiments 7-162 are not much different from those of the two-component self-crimped high-loft fiber spunbonded nonwovens B1-B6, so that the two-component self-crimped high-loft fiber spunbonded nonwovens B1-B6 are selected for comparative experiments.
Intercepting two-component self-crimping high-loft fiber spunbonded nonwovens B1-B6 and traditional spunbonded nonwovens C1-C6 with the same length and area, and respectively carrying out performance tests (such as crimping number, unit mass, loft, thickness and air permeability) on the B1-B6 and the C1-C6, wherein the obtained results are shown in Table 2.
Table 2: data sheet for performance of spunbonded nonwoven
The data in table 2 show that, under the condition of using the same raw material, the roll curvature, the unit mass, the thickness and the air permeability of the spunbond nonwoven fabric prepared by the conventional spunbond nonwoven fabric preparation process are all lower than those of the bicomponent self-crimping high-loft fiber spunbond nonwoven fabric provided by the invention, and although some data such as the roll curvature are not different greatly, the unit mass and the air permeability of the conventional spunbond nonwoven fabric are obviously not utilized under the similar roll curvature, and the spunbond nonwoven fabric prepared by the preparation method provided by the invention has the advantages of light unit mass and large air permeability.
In conclusion, the bicomponent self-crimping high-loft fiber spunbonded nonwoven provided by the invention has excellent performance.
Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described above, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
