Problems solved by technology

There are several problems in flocking non-woven fabrics in this way: 1. Flocking equipment (such as flocking machines), adhesives and flocking fluff must be equipped to realize flocking of non-woven fabrics, which increases equipment costs and Material cost; 2. The quality of the equipped flocking fluff directly affects the flocking effect. Once the flocking fluff is damp, it will not be able to flock, so it is necessary to prepare a dry and ventilated place to store the flocking fluff; 3. Adhesive The selection also has a great influence on the flocking effect. If the water resistance and bonding strength of the selected adhesive do not meet the requirements of non-woven fabrics and equipment control, the fluff on the manufactured non-woven fabrics will easily fall off; 4. The equipped flocking machine greatly increases the production line of non-woven fabrics, and the required floor area and space are relatively increased.

Embodiment 1

[0022] Embodiment 1: with reference to attached figure 1 , 2 , with processing attached figure 2 Take the non-woven fabric 5 with fluff 50 as an example. A spunlace flocking method, comprising the following steps,

[0023] ①Using fine denier fiber as raw material, the fiber web 8 formed in the forming net is transported to the spunlace machine through the transmission device, and the high-pressure spunlace head 4 is used for spunlace entanglement on the front and back sides;

[0024] ②After the spunlace reinforcement is completed, the fiber web 8 is transferred to the flocking drum 1 with tiny holes under the action of the transition drum 3;

[0025] ③ A plurality of high-pressure flocking spunlace heads 2 installed on the outside of the flocking drum 1 spray high-pressure fine water flow, and flush one end of the fiber on the fiber web 8 into the tiny holes of the flocking drum 1;

[0026] ④ Separate the flocked fiber web 8 from the flocking drum 1. At this time, the fib...

Embodiment 2

[0028] Embodiment 2: with reference to attached figure 2 , 3 , 4, with processing attached figure 1 Take the finished flocking non-woven fabric as an example. A spunlace flocking device, comprising a flocking drum 1, a plurality of high-pressure flocking spunlace heads 2 installed on the outside of the flocking spun drum 1, and a plurality of high-pressure flocking spunlace heads 2 arranged in a ring around the The outer side of the flocking drum 1; the flocking drum 1 has a plurality of tiny holes 7; the flocking drum 1 is composed of an outer layer nickel mesh 102 and an inner layer steel mesh 101; the outer layer nickel mesh 102 and the inner steel mesh 101 are uniformly arranged with a plurality of tiny holes 7; a transition drum 3 is provided between the hydroentanglement head 4 and the flocking drum 1 in the hydroentanglement process; 8 After the hydroentanglement and reinforcement of the hydroentanglement head 4, it is transported to the flocking drum 1 through the ...

Embodiment 3

[0029] Embodiment 3: with reference to attached figure 2 , 5 , with processing attached figure 1 Take the finished flocking non-woven fabric as an example. A spunlace flocking device, comprising a flocking trawl curtain 6, a plurality of high-pressure flocking spunlace heads 2 installed on the outside of the flocking trawl curtain 6, and a plurality of high-pressure flocking spunlace heads 2 evenly arranged on the The outer side of the velvet trawl curtain 6; the flocking trawl curtain 6 has a plurality of tiny holes 7; the flocking trawl curtain 6 is composed of an outer layer nickel mesh 601 and an inner layer nickel mesh 602 combined structure; the outer layer nickel mesh 601 and the inner nickel mesh 602 are evenly arranged with a plurality of tiny holes 7; a plurality of transition drums 3 are arranged between the hydroentanglement head 4 and the flocking trawl curtain 6 in the hydroentangling process; After the fiber web 8 is entangled and strengthened by the hydroen...

Abstract

The invention relates to a spunlace flocking device and a spunlace flocking method. The spunlace flocking device comprises a flocking wheel drum or trawl curtain and a high-pressure flocking spunlace head, wherein the high-pressure flocking spunlace head is arranged on the outer side of the locking wheel drum or trawl curtain; the locking wheel drum or trawl curtain is provided with a plurality of fine holes; after a fiber net is tangled through front spunlace, one ends of fine fibers extend into the fine holes through the flocking wheel drum or trawl curtain under the action of the spunlace of the high-pressure flocking spunlace head, and the ends of the fibers extending into the concave holes are taken out when non-woven fabric is separated from the flocking wheel drum or trawl curtain, so that flocks are formed on one face of the non-woven fabric to finish a flocking process for flocking the non-woven fabric. By using the spunlace flocking method, the flocking process of the non-woven fabric is simplified, the used device has the characteristics of simple structure, reduction in floor space and reduction in equipment and material cost, and the flocking effect of the non-woven fabric is also effectively guaranteed.

Description

technical field [0001] The invention relates to a non-woven fabric production technology, in particular to a spunlace flocking method and device for processing non-woven fabric surface fluff, and belongs to the technical field of non-woven fabric processing. Background technique [0002] In the current field of non-woven fabric manufacturing, in order to produce non-woven fabrics with fluff on the surface, they are all processed by electrostatic flocking technology. For example, the Chinese patent No. ZL201120537140.4 utility model patent discloses a flocking non-woven fabric, which is to coat a layer of adhesive layer on the surface of the non-woven fabric, and then use the electrostatic flocking process to plant the fluff. It is inserted into the non-woven fabric, and the fluff layer is combined with the non-woven fabric body by the adhesive force of the adhesive layer. There are several problems in flocking on non-woven fabrics in this way: 1. Flocking equipment (such as...
