At present, spunlace nonwoven fabric products are well favored by customers at home and abroad, and are widely applied to the fields of household life, personal care, medical sanitation, light industry, electronics, environmental protection and the like. With the rapid development and market segment of spunlace nonwoven fabrics, wet tissues for infants have become a main part of the wet tissue market for personal care and home life, and with the opening of the birth policy of the country, the wet tissues for infants will enter a stage of rapid development. In China, 3000 million babies are born every year, wherein 4500 million babies are born at 8-36 months of age, 312 hundred million children are born, and 8000 million consumers are born for 0-4 years old. It is seen that the baby wet tissue has a large target consumer group in China, but the market is developed by 20 percent at present. The domestic wet tissue for the babies can show a strong development prospect within 10-20 years in the future.

The infant time products in the market mainly use common spunlace non-woven fabrics as the main materials, the conventional spunlace non-woven fabrics are mainly made of short fibers such as terylene or viscose, the problems of poor water absorption, high raw material cost, insufficient handfeel flexibility and the like exist, the expansion of the product market is limited to a certain extent, and wood pulp composite products have the problems of chip falling and poor use thickness, so that a product which can solve the problems and has water absorption and use handfeel is needed at present.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects in the background technology and provide the CPC spunlace composite non-woven fabric which has good water absorption, soft hand feeling and fluffy and thick hand feeling experience in the use process and is an ideal infant wet tissue product.

The technical scheme adopted by the utility model for solving the technical problems is as follows: a CPC spunlace composite nonwoven fabric comprises three layers, namely a carding fiber net layer A, a wood pulp fiber net layer and a carding fiber net layer B, wherein the topmost layer is the carding fiber net layer A, the middle layer is the wood pulp fiber net layer, and the bottom layer is the carding fiber net layer B; and the carded fiber web layer A and the wood pulp fiber web layer are mutually entangled and connected to obtain a web layer, and the web layer and the carded fiber web layer B are mutually entangled and connected to obtain the CPC spunlaced composite nonwoven fabric.

Furthermore, the raw material of the carded fiber web layer A comprises one or more than two of viscose fiber, tencel, bamboo fiber or PLA fiber, the fiber length is 30-50mm, the titer is 1.5-1.7dtex, and the gram weight is 27-35 gsm.

Further, the wood pulp fiber net layer has the fiber length of 1-3mm and the gram weight of 11-25 gsm.

Furthermore, the raw material of the carded fiber web layer B is one or more than two of cotton fiber, viscose, terylene and bamboo fiber, the fiber length is 30-50mm, the titer is 1.5-1.7dtex, and the gram weight is 20-50 gsm.

The carding fiber web layer A and the wood pulp fiber web layer are planted between fibers of the carding fiber web layer A under the action of the high-pressure water jet, the fibers and the fiber web layer are mutually entangled and connected, the carding fiber web layer A provides soft hand feeling and better using strength for products, the wood pulp fiber web layer endows the products with better water absorption performance, and the carding fiber web layer B can effectively increase the thickness of the products, so that the products have fluffy and thick hand feeling experience in the using process.

Compared with the prior art, the utility model has the beneficial effects that:

the CPC spunlace composite nonwoven fabric provided by the utility model is simple in structure and divided into three layers, the carding fiber web layer A on the upper layer and the wood pulp fiber web layer on the middle layer are compounded through a wet spunlace process, namely, the fiber web formed by short fibers through the carding process and the wood pulp fiber layer formed by a pulp distributor are mutually entangled and connected under the action of a high-pressure water jet, are compounded through a one-time spunlace process, and are finally compounded with the carding fiber web layer B through a dry spunlace secondary entanglement process, so that the problem of chip falling of the wood pulp fiber web layer can be effectively solved, the strong use strength and fluffy and thick hand feeling experience of a product are ensured, and meanwhile, the product is endowed with excellent water absorption performance.
