Spunlace composite technology can be reinforced through the tangles of the layers of material prepared with a high-performance, multi-functional new materials. Wood pulp fiber is a natural cellulose fiber, biodegradable, wide variety of sources, is an ideal green raw fiber. The topics chosen green raw materials, the use of new non-woven spunlace technology research and development CPC composite, both to meet the performance requirements of the material, they can resolve the sources of raw materials used disposable items. This article describes the CPC into a network and reinforcement technology, based on deep understanding of raw performance, the analysis of the wood pulp paper ease in the the water needle role under tangled with each other as well as with chemical fiber mechanism groping the CPC production of optimum process configuration parameters as well as the solution of the technical problems, and CPC spunlace composites mechanical properties, absorption properties and permeability can be carried out test analysis. Contrast and ordinary kraft paper, wood pulp wrinkles facial tissue tensile strength is low, water absorption, and the cross-section was flat, the moment of inertia of small, the water needle role under easy ease and polyester, viscose fibers tangled with each other, it is the most suitable the spunlace process of fiber one. The experimental single-factor experimental methods, the use of all technology program of the fuzzy decision Borda number method. Analysis available more than viscose, polyester fiber suitable for the preparation of CPC, and to control the quality of the wood pulp paper in the CPC percentage of 20% to 30%; process should be used on the low-pressure multi-channel, two positive and two anti-alternating the spunlace the way CPC molding pre-wet technique is very important and should be controlled pre-wet the spunlace head to the first spunlace head running time ≥ 0.5s; production requires the use of the tension control device to unwinding, composite synchronization requirements, and microporous network The curtain is more suitable than the braid CPC molding and reinforcement. Formula derivation and calculation, when the the spunlace pressure 100bar, water injection speed 135.77m / s, water pin impact only 0.215N energy coefficient of 9.6 × 10 ~~ 4. The impact of the water for the fiber network is an extremely flexible, impact, small fiber damage. Spunlace increased energy spunlace composites CPC tangles coefficient BI and fiber strength utilization factor to QLV followed first increase and then decreased, and significant linear relationship between QLV and BI. Wood pulp paper ease in the water jet under broadly divided into five processes: theoretical analysis, surface contact, dissolution of chemical additives, fiber swelling, fiber further swelling and kraft paper ease. Kraft paper of the slurry formed by the water needle, the congestion factor N 42.46 LT; 60, but are subject to certain limitations can occur translational rotation DOF maximum. Wood pulp fiber and chemical fiber mainly rely on hydrogen bonding, the tangles form of addition to the cross-cutting, entanglement, \The relatively ordinary spunlace material is not wood pulp paper composite, the CPC feel more fluffy and plump capillary wicking and moisture water retention is also good, but both permeability little difference. The tensile strength of CPC mainly rely on chemical webs, pulp paper to join the MD / CD ratio can be greatly reduced. CPC tensile fracture process is roughly divided into three stages: First, chemical fiber straight and slip; second phase of chemical fiber tensile fracture stage; Finally, some of the wood pulp fiber fracture stage.
