Abstract
The utility model discloses a sandwich formula by core structure, include by jacket layer, wadding layer and intermediate course, the quantity on wadding layer be more than two, and the quantity of intermediate course be more than one, presss from both sides between two wadding layers and is equipped with the intermediate course, and the intermediate course be the composite construction of well high density fabric OR function film, and the wadding layer more than two and more than one's intermediate course superpose and form insulation construction, and insulation construction's both ends are the wadding layer, and insulation construction outside is adopted by the jacket layer parcel and intermediate course and passed through to sew the stitch by the mode of jacket layer adoption large needle foot and fix. This product simple structure, reasonable in design, low in production cost, the safety in utilization is good, intermediate course be equipped with through pressing from both sides between the wadding layer, under the same thermal insulation performance's prerequisite, the whole thickness and the weight of quilt can be reduce, wadding level in upper and lower two sides, the sense of touch is soft, uses the travelling comfort good, is convenient for foldingly and deposits.
Description
Technical field
This utility model relates to a kind of by cored structure, a kind of sandwich style by cored structure.
Background technology
Quilt isBeddingOne, be that a kind of area be enough to cover human body, rectangularCloth, it is typically used as during sleep protectingWarmWith.Quilt is typically constituted by three layers: middle batt layer, outmost by cap layer, and centre by jacket layer.The most outmost by cap layer generally as independent commodity selling, user freely configure, change, wash.Quilt in selling in traditional sense is the most only constituted by batt layer with by jacket layer, and batt layer and quilt cover lamination claim quilt core.Traditional quilt core, its batt layer is typically made up of one pack system or the multicomponent of natural fiber with synthetic fibers, it is desirable to consistency of thickness everywhere.The heat preservation principle of quilt is: density and thickness with material block heat radiation and thermal convection current, reduce conduction of heat with the low thermal conductivity of material, so general materials the most (i.e. quilt core thickness is the biggest) then heat-insulating property is the best.In conventional monolayers batt layer structure, heat insulation effect to be improved, the thickness of batt layer can only be increased, on the one hand can increase the weight of the overall weight of quilt, and cost can be increased, on the one hand quilt then can be made to be inconvenient to fold and deposit because of thick and heavy causing.
Utility model content
The purpose of this utility model be to provide a kind of sandwich style by cored structure, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of sandwich style by cored structure, including by jacket layer, batt layer and intermediate course, the quantity of described batt layer is two or more, the quantity of intermediate course is more than one, it is folded with intermediate course between two batt layer, intermediate course is the composite construction of middle-high density fabric or function film, plural batt layer and more than one intermediate course are overlapped forming insulation construction, the two ends of insulation construction are batt layer, insulation construction outside uses is wrapped up by jacket layer and intermediate course and used the mode of big stitch to be fixed by sewing stitch by jacket layer, low-density fabric is used to constitute by jacket layer, the function film of intermediate course is PTFE film or PU film.
Compared with prior art, the beneficial effects of the utility model are: this product structure is simple, and reasonable in design, production cost is low, and safety in utilization is good；By being folded with intermediate course between batt layer, on the premise of identical heat-insulating property, integral thickness and the weight of quilt can be reduced；Batt layer is positioned at upper and lower surface, soft-touch, and comfort is good, it is simple to folds and deposits.
Accompanying drawing explanation
Fig. 1 be sandwich style by a kind of structural representation of cored structure.
Fig. 2 be sandwich style by the another kind of structural representation of cored structure.
Wherein: 1-is by jacket layer, and 2-batt layer, 3-intermediate course, 4-sews stitch.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical scheme of this patent is described in more detail.
Refer to Fig. 1-2, a kind of sandwich style by cored structure, including by jacket layer 1, batt layer 2 and intermediate course 3, the quantity of described batt layer 2 is two or more, the quantity of intermediate course 3 is more than one, it is folded with intermediate course 3 between two batt layer 2, intermediate course 3 is the composite construction of middle-high density fabric or function film, plural batt layer 2 and more than one intermediate course 3 are overlapped forming insulation construction, the two ends of insulation construction are batt layer 2, insulation construction outside uses is wrapped up by jacket layer 1 and intermediate course 3 and used the mode of big stitch to be fixed by sewing stitch 4 by jacket layer 1, low-density fabric is used to constitute by jacket layer 1, the function film of intermediate course 3 is PTFE film or PU film.
Operation principle of the present utility model is: between this product utilization batt layer 2, sandwiched has the intermediate course 3 of the composite construction of middle-high density fabric or function film, for more single batt layer 2, this product can reach single batt layer 2 to thermal convection current and thermal-radiating blocking ability with the least thickness, thus on the premise of identical heat-insulating property, can reduce by the integral thickness of cored structure and weight, or on the premise of same thickness, can improve largely by the heat-insulating property of cored structure.Simultaneously as batt layer 2 is at upper and lower surface, remain the advantage that tradition quilt core textural feel is soft.This product structure is simple, and reasonable in design, production cost is low, and safety in utilization is good；By being folded with intermediate course 3 between batt layer 2, on the premise of identical heat-insulating property, integral thickness and the weight of quilt can be reduced；Batt layer 2 is positioned at upper and lower surface, soft-touch, and comfort is good, it is simple to folds and deposits.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art is possessed, it is also possible to make a variety of changes on the premise of without departing from this patent objective.
