Beneficial effects of the present invention: compared with prior art, a kind of pro-skin lateral leakage protection amenities table provided by the invention Layer, uses the hot-wind nonwoven cloth being made of ES fiber for upper layer, and non-woven cotton is lower layer, compound by spun lacing, and ES is fine The intertexture of peacekeeping cotton fiber can promote liquid is quickly lower to seep, and ensure that the dry and comfortable of hot-wind nonwoven cloth pro-skin face, meanwhile, cotton fiber The liquid of absorption can orient the moisture absorption layer for being transferred to amenities, further ensure the absorption efficiency to liquid, it is ensured that defend The dry and comfortable of articles surface layer pro-skin face is given birth to, while preventing the side leakage of liquid, the present invention also passes through two-sided spun lacing reinforcement process and carries out It is compound, it ensure that the entanglement strength of hot-wind nonwoven cloth and non-woven cotton, while improving the uniformity of non-woven fabrics, and adopt With soft drying twice, the soft skin affinity of non-woven cloth ensure that.
Feature and advantage of the invention will be described in detail by embodiment combination attached drawing.
[Detailed description of the invention]
Fig. 1 is a kind of stratiform schematic diagram on pro-skin lateral leakage protection amenities surface layer of the embodiment of the present invention.
In figure: 1- hot-wind nonwoven cloth, 2- non-woven cotton.
[specific embodiment]
In order to make the objectives, technical solutions and advantages of the present invention clearer, below by accompanying drawings and embodiments, to this Invention is further elaborated.However, it should be understood that the specific embodiments described herein are merely illustrative of the present invention, The range being not intended to restrict the invention.In addition, in the following description, descriptions of well-known structures and technologies are omitted, to keep away Exempt from unnecessarily to obscure idea of the invention.
Refering to fig. 1, the embodiment of the present invention provides a kind of pro-skin lateral leakage protection amenities surface layer, is answered by upper layer and lower layer non-woven fabrics It closes, upper layer is the hot-wind nonwoven cloth 1 of pro-skin, and lower layer is non-woven cotton 2, the hot-wind nonwoven cloth 1 and cotton Spunlace non-woven cloth 2 is complex as a whole by spun lacing.
Further, the grammes per square metre of the hot-wind nonwoven cloth 1 is 12~20g/m2, the non-woven cotton 2 Grammes per square metre is 23~35g/m2；The hot-wind nonwoven cloth 1 uses ES fiber for raw material, and the sandwich layer of the ES fiber uses Gao Rong The PP or dystectic PET of point, cortex use the PE of low melting point, and the fineness of the ES fiber is in 1.2D or less；Described is complete Cotton fiber used in cotton spunlace non-woven cloth 2 uses the white cotton of normal mature, normal blow-of-cottons.
In embodiments of the present invention, the hot-wind nonwoven cloth 1 on upper layer uses ES fiber, and ES fiber itself has certain hydrophilic Property, and ES fibrous crimpness is high, and the non-woven cloth of production has many advantages, such as that fluffy, soft, pro-skin, elasticity is good, fiber it is fluffy Pine, the characteristics of elasticity is good, ensure that the dry-ness of amenities surface layer；The use of non-woven cotton 2 normal mature of lower layer, The natural plants cotton fiber of normal blow-of-cottons, it is non-stimulated to skin safe, and also cotton fiber can quickly absorb water, and prevent urine side leakage.
The embodiment of the present invention also proposed a kind of processing technology on pro-skin lateral leakage protection amenities surface layer, including walk as follows It is rapid:
S1, using dystectic PP or dystectic PET as core layer raw material, the PE of low melting point is as cortex raw material, warp Melt spinning obtains ES fiber, selected after cooling drawing-off fineness 1.2D ES fiber below according to this laying, hot blast adhesion at heat Wind non-woven fabrics 1, it is spare.
S2, the white cotton for selecting normal mature, normal blow-of-cottons, successively through shredding twice, height mixed and disorderly processing, networking, lapping It is spare by obtaining non-woven cotton 2 after spun lacing reinforcement process and soft drying at cotton fibre web.
Wherein, shredding twice is handled using first thick shredding, the mode of rear essence shredding；The mixed and disorderly processing of height is using high speed The mixed and disorderly mechanism of combined type on mixed and disorderly carding machine carries out the mixed and disorderly processing of height, and the mixed and disorderly mechanism of the combined type is using double mixed and disorderly rollers The combining form of+two pairs of husband of+two pass cohesion rollers；It is used at net mode and combs networking or airlaid；Lapping is using parallel One of lapping, semidecussation lapping or cross lapping.
In embodiments of the present invention, the mixed and disorderly processing of height is carried out using the mixed and disorderly mechanism of combined type, it is good miscellaneous meets throughput rate The requirement of random effect, and the uniformity after networking is high, reduces vertical and horizontal quality ratio, anisotropy is small.
S3, hot-wind nonwoven cloth 1 and non-woven cotton 2 are combined into compound nonwoven cloth by spun lacing reinforcement process.
Wherein, spun lacing reinforcement process uses two-sided spun lacing reinforcement process, and spun lacing pressure is 80~100bar, improves non-woven fabrics Entanglement strength and uniformity.
S4, compound nonwoven cloth are dried using soft drying and processing twice, obtain compound nonwoven cloth finished product.
Wherein, soft drying and processing uses first cylinder hot wind to penetrate drying cylinder formula drying after drying, the cylinder heat twice Wind penetrates the temperature control of drying at 140~150 DEG C, and the temperature of drying cylinder formula drying is controlled at 120~130 DEG C, and use is soft twice And drying and processing, it ensure that the soft skin affinity of non-woven cloth.
Further, after the drying, punching processing can be also carried out according to actual selection, compound nonwoven cloth or does not punch place Reason.
S5, compound nonwoven cloth finished product are wound into a roll by up- coiler.
A kind of pro-skin lateral leakage protection amenities surface layer of the present invention, uses the hot-wind nonwoven cloth 1 being made of ES fiber for upper layer, Non-woven cotton 2 is lower layer, compound by spun lacing, and the intertexture of ES fiber and cotton fiber can promote liquid is quickly lower to seep, It ensure that the dry and comfortable of hot-wind nonwoven cloth pro-skin face, meanwhile, the liquid that cotton fiber absorbs can orient the moisture absorption for being transferred to amenities Layer, further ensures the absorption efficiency to liquid, it is ensured that amenities surface layer pro-skin face it is dry and comfortable, while preventing liquid Side leakage, the present invention also by two-sided spun lacing reinforcement process carry out it is compound, ensure that hot-wind nonwoven cloth 1 and non-woven cotton 2 entanglement strength, while the uniformity of non-woven fabrics is improved, and use soft drying twice, it ensure that the softness of non-woven cloth Skin affinity.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention Made any modification, equivalent replacement or improvement etc., should all be included in the protection scope of the present invention within mind and principle.
