Problems solved by technology

Although the domestic spunlace nonwoven production line occupies a relatively large proportion in the domestic market, my country's spunlace nonwoven industry started late, and our country does not yet have advanced material processing technology and manufacturing precision. At present, domestic spunlace nonwoven equipment is still in the In the imitation stage, the core components of the equipment still rely on imports, such as card clothing for carding machines, carbon curtains for net-laying machines, net curtains for spunlace machines, and jet plates, etc.

Embodiment 1

[0034] A control process for the production of nonwovens, characterized in that:

[0035] (1) grabbing step;

[0036] (3) Pre-opening step

[0037] The main function of the pre-opening step is to decompose the larger fiber bundles into smaller fiber bundles, which is beneficial to the removal of impurities and lays the foundation for the mixing equipment to improve the mixing effect;

[0038] (3) Mixing step

[0039] In the processing flow of non-woven fabrics, there are two commonly used mixing equipments: large bin blender and multi bin blender, and users can choose the appropriate model according to actual needs;

[0040] (4) Fine opening and loosening steps

[0041] The main function of the fine opening equipment is to decompose the fiber bundles into small and uniform fiber bundles suitable for the feeding requirements of the carding machine, and remove part of the impurities according to the impurities in the fibers;

[0042] (5) Finishing cotton box steps

[0043] ...

Embodiment 2

[0059] A control process for the production of nonwovens, characterized in that:

[0060] (1) grabbing step;

[0061] (4) Pre-opening step

[0062] The main function of the pre-opening step is to decompose the larger fiber bundles into smaller fiber bundles, which is beneficial to the removal of impurities and lays the foundation for the mixing equipment to improve the mixing effect;

[0063] (3) Mixing step

[0064] In the processing flow of non-woven fabrics, there are two commonly used mixing equipments: large bin blender and multi bin blender, and users can choose the appropriate model according to actual needs;

[0065] (4) Fine opening and loosening steps

[0066] The main function of the fine opening equipment is to decompose the fiber bundles into small and uniform fiber bundles suitable for the feeding requirements of the carding machine, and remove part of the impurities according to the impurities in the fibers;

[0067] (5) Finishing cotton box steps

[0068] ...

Embodiment 3

[0084] A control process for the production of nonwovens, characterized in that:

[0085] (1) grabbing step;

[0086] (5) Pre-opening step

[0087] The main function of the pre-opening step is to decompose the larger fiber bundles into smaller fiber bundles, which is beneficial to the removal of impurities and lays the foundation for the mixing equipment to improve the mixing effect;

[0088] (3) Mixing step

[0089] In the processing flow of non-woven fabrics, there are two commonly used mixing equipments: large bin blender and multi bin blender, and users can choose the appropriate model according to actual needs;

[0090] (4) Fine opening and loosening steps

[0091] The main function of the fine opening equipment is to decompose the fiber bundles into small and uniform fiber bundles suitable for the feeding requirements of the carding machine, and remove part of the impurities according to the impurities in the fibers;

[0092] (5) Finishing cotton box steps

Abstract

The invention relates to the technical field of spunlace non-woven devices, in particular to a control process for producing a non-woven fabric. The control process is characterized by including the following steps of firstly, grabbing; secondly, pre-loosening; thirdly, mixing; fourthly, fine-loosening; fifthly, processing by a final hopper; sixthly, processing by a pneumatic hopper; seventhly, spunlacing; eighthly, drying; ninthly, winding. An automatic winding machine has a quite high automation level and can realize continuous online production of automatic repiecing, lap changing and lap falling.

Description

technical field [0001] The invention relates to the technical field of spunlace nonwoven equipment, in particular to a control process for nonwoven fabric production. Background technique [0002] The raw spunlace nonwoven process originated in the United States, but its further development is in Europe. At present, Europe is ahead of the United States in terms of spunlace nonwoven equipment. European countries focus on the research and manufacture of industrial equipment, while the United States focuses on the added value research of spunlace products. After more than 30 years of development, European spunlace equipment has become the most advanced level in the world. Its spunlace equipment has the characteristics of wide width, high speed and high output, high degree of mechanical and electrical integration, automation, and intelligence, and its process is becoming more and more targeted. Strong, the capacity utilization rate of its equipment can reach more than 70%, and s...
