Embodiment 1

[0016] The processing method of a three-layer composite spunlace nonwoven material referred to in this embodiment is: the upper and lower layers are made of 100% polyester, and the 100% polyester is opened and then sent to a carding system to form an upper web of 17g / m 2 , 100% polyester is fully opened and sent to another carded web system to form the lower web of 17g / m 2 , The weight of the middle layer is 13g / m 2 , The fiber length is 2-15mm wood pulp paper after unwinding wet method. The three-layer material is superimposed on the bottom curtain, and the composite material formed is sent to the spunlace machine, where the three-layer composite material is repeatedly acted on by water needles in the spunlace machine to make it entangled and reinforced, and then the excess water is removed by the dryer. Finally wound into 45g / m 2 The spunlace composite nonwoven material, which is suitable for wiping cloth.

Embodiment 2

[0018] The processing method of a three-layer composite spunlace nonwoven material referred to in this embodiment is: the upper layer is fully mixed and opened with 50% viscose and 50% polyester and then sent to the web forming system. The web forming system is a cross-laid web. The cross web is drawn to form 20g / m 2 The upper web, the lower web is fully mixed with 50% viscose and 50% polyester, and then sent to the carded web system to form 25g / m 2 The fiber of the middle layer is 5mm, and the wet wood pulp paper is 16g / m after unwinding and wet process. 2 . The three-layer material is superimposed on the bottom curtain to form a composite material, and then sent to the spunlace machine. The three-layer composite material is repeatedly applied to the three-layer composite material by repeated water needles in the spunlace machine to make it entangled and strengthened, and then the excess water is removed by the dryer. Finally wound into 60g / m 2 The three-layer spunlace composite ...

Embodiment 3

[0020] The processing method of a three-layer composite spunlace nonwoven material referred to in this embodiment is as follows: the upper layer is made of 100% viscose as the raw material, and is fully opened and then sent to the cross-laid system to form 30g / m 2 The upper layer of fiber web, the lower layer is made of 100% viscose. After being fully opened, it is sent to the cross-forming system to form 30g / m 2 Fiber web, the middle layer is made of wet wood pulp paper with a fiber length of 10mm after unwinding and wet process 26g / m 2 . The composite material formed by superimposing the three-layer material on the bottom curtain is then sent to the spunlace machine, where the three-layer composite material is repeatedly applied by water needles in the spunlace machine to make it entangled and strengthened, and then the excess water is removed by the dryer. Finally wound into 85g / m 2 The three-layer spunlace composite material is suitable for beauty products.

Abstract

The invention discloses a process for preparing three-layer compound water-jetting unwoven material, which comprises firstly, respectively mixing raw material which is used as an upper layer and a lower layer, feeding fiber which is handled by an opening and mixing device into two sets of web forming systems, utilizing fiber sheets which are respectively formed by fiber raw material which is used as the upper layer and the lower layer in the web forming system to be the upper layer and the lower layer of a three-layer compound water-jetting unwoven product, utilizing an uncoil-stand device to withdraw a layer of wood-pulp paper between the upper layer and the lower layer to be raw material of a middle layer, superimposing material of the three layer at a bottom curtain, feeding the compound material in a water-jetting machine after superimposing, leading the compound material of the three layers through the repeat action of a water jet in the water-jetting machine for many times to tangle and reinforce, and then dying and winding to be a coil. The invention utilizes wet-process wood-pulp paper to be clipped between two-layer fiber sheets to jet, tangle and reinforce, which effectively solves the water absorbing performance, and has the advantages of rich handle feeling, big water absorbing amount, short water absorbing time, low flokkit property and excellent shielding property, and the invention can effectively lower the production cost of raw material of products.

Description

Technical field [0001] The invention relates to a processing method of a three-layer composite spunlace nonwoven material. Background technique [0002] At present, the sanitary materials such as wipes and wet wipes on the market are generally reinforced by spunlace after forming a web of ordinary fibers. This kind of products are mostly made of polyester and viscose by a simple mixture of two-layer materials, which makes the product low in water absorption and easy Fuzzing and loose hand feeling. Due to the high market price of viscose, the finished product price is high. Summary of the invention [0003] The purpose of the present invention is to provide a three-layer composite spunlace nonwoven material processing method, the product produced by this method has the use of wet wood pulp paper sandwiched between two fiber webs for hydroentanglement reinforcement, effective It solves the advantages of water absorption performance, rich hand feel, large water absorption, short wa...
