Description
The technical field is as follows:
the utility model belongs to the technical field of the non-woven fabrics, concretely relates to dry process papermaking non-woven fabrics who contains china-hemp fibre.
Background art:
the traditional dry-method papermaking non-woven fabric is formed by bonding wood pulp fibers and hot-melt fibers through a thermal bonding method and is generally used for a packaging layer of a feminine hygiene product, the dry-method papermaking non-woven fabric is applied to the ultrathin core body of the baby diaper after 2010, and the application field of the dry-method papermaking non-woven fabric is greatly expanded. In recent years, many functional studies on dry-process papermaking nonwoven fabrics have been made, for example, chinese patent CN201220714931.4 discloses a composite dust-free paper having a structure of: the first layer is a bottom lining layer which is made of non-woven materials, the second layer comprises cellulose fibers, bonding materials and high polymer absorbing materials, the third layer comprises high polymer water absorbing materials, the cellulose fibers and optional double-component composite fibers, and the fourth layer can comprise the cellulose fibers, the double-component composite fibers and the high polymer water absorbing materials; chinese patent CN201320025185.2 discloses a differential liquid-absorbing type solid water composite dust-free paper, which is characterized in that: the dust-free paper comprises top dust-free paper with liquid permeability and wet strength, a second high-molecular water-absorbing resin layer with lower water absorption rate, a third fluffy non-woven fabric or hydrophilic fabric with liquid diffusibility, a fourth high-molecular water-absorbing resin layer with high water absorption rate and bottom dust-free paper with liquid permeability and wet strength, wherein the layers are bonded together through bonding layers, and the lower high-molecular water-absorbing resin layer is subjected to liquid absorption locking in advance by utilizing the difference of the liquid absorption rates of the upper high-molecular water-absorbing resin layer and the lower high-molecular water-absorbing resin layer, so that the liquid absorption amount of the upper high-molecular water-absorbing resin layer is relatively small; the surface liquid of the sanitary products such as diapers and the like adopting the composite dust-free paper has small back-seepage amount, so that the skin of a wearer feels dry and not moist. However, these prior arts are still deficient in bacteriostatic function, and it is necessary to develop a dry-process papermaking nonwoven fabric which is bacteriostatic and naturally harmless.
The utility model has the following contents:
the utility model aims at solving the problem in the prior art, providing a dry process papermaking non-woven fabrics that contains china-hemp fibre, can improve non-woven fabrics's antibacterial effect, prevent red butt and the anaphylactic phenomenon because of bacterial growing leads to.
In order to realize the purpose, the utility model provides a dry papermaking non-woven fabric containing hemp fibers, the main structure of which comprises a hemp fiber layer, a hot melt fiber layer and a wood pulp fiber layer, wherein the hot melt fiber layer is positioned between the hemp fiber layer and the wood pulp fiber layer; the China-hemp fiber layer and the hot-melt fiber layer as well as the hot-melt fiber layer and the wood pulp fiber layer are bonded by a hot bonding method.
Furthermore, the dry method papermaking nonwoven containing hemp fiber has the thickness of 0.1-0.5mm, the gram weight of 30-60 g/square meter, the longitudinal breaking strength of more than 15N/cm and the transverse breaking strength of more than 5N/cm.
Further, the hemp fiber layer is composed of hemp fibers obtained from industrial hemp.
Furthermore, the fiber length of the hemp fiber is 6-9mm, and the fineness is 15-30 μm.
Further, the hot-melt fiber layer is composed of low-melting polyolefin fibers.
Further, the wood pulp fiber layer is composed of wood pulp fibers.
Compared with the prior art, the utility model, through adopting china-hemp fibre, hot melt fibre, wood pulp fibre as the raw materials with the non-woven fabrics, through the preparation of hot bonding legal process, no adhesive, through the thermal bonding form non-woven fabrics surface and three-dimensional direction on intensive distribution a large amount of gaps, strengthened its adsorption efficiency, can effectively absorb human body fluid, china-hemp fibre layer can restrain bacterial growing, be fit for being applied to women's health supplies wrapping layer and the ultra-thin core of baby diaper; the novel antibacterial agent has the advantages of simple structure, low cost, natural bacteriostasis, no chemical agent, good bacteriostasis effect, wide market prospect and good application environment.
