Problems solved by technology

[0002] The traditional non-woven yarn production process is cotton blending-pre-opening-main opening-carding-laying-drying-winding. The above-mentioned non-woven yarn preparation process can only form a variety of fibers through single-line carding and laying. The single-layer bulky structure filling cannot layer different fibers, and there are defects in its bulkiness, warmth retention and independent layering of different fibers

preparation example Construction

[0105] The present invention also provides a method for preparing the above layered structure filling, comprising the following steps:

[0106] A) mixing and stirring the fibers and pre-opening to obtain the first mixed fibers;

[0107] Mixing, stirring and pre-opening the fibers to obtain the second mixed fibers;

[0108] B) performing main opening, carding and laying of the first mixed fiber in sequence to obtain the first fiber flake precursor;

[0109] Performing main opening, carding and laying of the second mixed fibers in sequence to obtain a second fiber flake precursor, and laying on the first fiber flake precursor to obtain a layered structure filler precursor;

[0110] C) The layered structure filler precursor is sequentially drawn, dried, ironed and cooled to obtain a layered structure filler.

[0111] see image 3 , image 3 The process flow diagram for the preparation of the layered structure filler provided by the present invention. Specifically, in the pre...

Embodiment 1～28

[0200] Embodiments 1-28 are the preparation methods of two-layer structure fillers, specifically:

[0201] According to the raw material formula in Table 1, various baled fibers of different specifications used to prepare the first fiber flakes were uniformly stirred and mixed in a cotton mixing box according to a set ratio to obtain a mixed raw material.

[0202] The obtained mixed raw material is decomposed in the opener, so that the mixed raw material is in a fluffy state, no longer agglomerated, and the first mixed fiber is formed, and the first mixed fiber is transported to the next process through the cotton conveying fan .

[0203] At the same time, according to the raw material formula in Table 1, various baled fibers of different specifications used to prepare the second fiber flakes were uniformly stirred and mixed in the cotton mixing box according to the set ratio to obtain the mixed raw material.

[0204] The obtained mixed raw materials are preliminarily decompo...

Embodiment 29～56

[0226] Examples 29-56 are the preparation methods of two-layer structure fillings, specifically:

[0227] According to the raw material formula in Table 3, various bundled fibers of different specifications used for preparing the first fiber flakes were uniformly stirred and mixed in a cotton mixing box according to a set ratio to obtain a mixed raw material.

[0228] The obtained mixed raw material is decomposed in the opener, so that the mixed raw material is in a fluffy state, no longer agglomerated, and the first mixed fiber is formed, and the first mixed fiber is transported to the next process through the cotton conveying fan .

[0229] At the same time, according to the raw material formula in Table 3, various baled fibers of different specifications used to prepare the second fiber flakes were uniformly stirred and mixed in the cotton mixing box according to the set ratio to obtain the mixed raw material.

[0230] The obtained mixed raw materials are preliminarily dec...

Abstract

The invention provides layered structure filler which comprises first fiber wadding (1) and second fiber wadding (2) combined to the first fiber wadding (1). Through layered arrangement of the fiber wadding, the filler has excellent bulkiness and thermal insulation property, and independent and flexible layering and diversified combination of different composition fibers can be realized. A result shows that the provided layered structure filler is 1-10 cm thick and has a clo value larger than or equal to 5.0.

Description

technical field [0001] The invention belongs to the technical field of fillers, and in particular relates to a layered structure filler and a preparation method thereof. Background technique [0002] The traditional non-woven yarn production process is cotton blending-pre-opening-main opening-carding-laying-drying-winding. The above-mentioned non-woven yarn preparation process can only form a variety of fibers through single-line carding and laying. The filler of the single-layer block structure cannot layer different fibers, and there are defects in its bulkiness and warmth retention and the independent layering of different fibers. Contents of the invention [0003] In view of this, the technical problem to be solved by the present invention is to provide a layered structure filling and its preparation method and application. The layered structure filling provided by the present invention has good bulkiness and warmth retention, and can realize different composition Ind...
