Production Process Differences Between Kitchen Towel Paper and Ordinary Toilet Paper (Based on NRC1880 Rewinder Machine)

Обзор

Kitchen towel paper and ordinary toilet paper are both converted from jumbo parent tissue paper rolls on the NRC1880 fully automatic tissue rewinding production line. The front-end pulping and papermaking processes are basically the same, while the core differences focus on the rewinding and post-processing stage controlled by the machine’s gluing and laminating composite system. The flexible function switching of the NRC1880 toilet paper machine realizes two completely different production processes, forming functional differences in paper thickness, toughness, oil absorption and water resistance.

1. Core Process Difference: Gluing & Laminating Composite Procedure

Kitchen Towel Paper Production (Gluing & Laminating Function ON)

The most essential production step for kitchen towels is the multi-layer gluing and laminating composite process. After unwinding and preliminary embossing, the NRC1880 rewinder machine activates the closed glue spraying system. The stainless steel glue tank and anilox transfer roller evenly apply food-safe adhesive between multiple layers of parent tissue paper. Under precise pressure lamination, the multi-layer paper sheets are tightly bonded as a whole.

This exclusive process greatly improves the overall compactness, tensile strength and structural stability of the paper. The finished kitchen towel is thick, tear-resistant, oil-absorbent and waterproof, which will not break or leave paper scraps when wiping oil stains, water spills and food residues. This is the key craft that ordinary toilet paper does not have.

Ordinary Toilet Paper Production (Gluing & Laminating Function OFF)

When producing ordinary household toilet paper, the operator directly turns off the gluing and laminating composite system of the NRC1880 toilet paper machine. The equipment cancels all glue spraying and multi-layer bonding procedures, and only retains single-layer or simple multi-layer soft rewinding and embossing processes.

Without adhesive lamination, the paper maintains soft, lightweight and fluffy characteristics, with good water solubility. It is comfortable for body hygiene use and can dissolve quickly after flushing, avoiding pipeline blockage, fully meeting the daily bathroom use standards of ordinary toilet paper.

2. Embossing & Tension Control Process Difference

Kitchen Towel Embossing Process

For kitchen towel production, the NRC1880 machine adopts point-to-face deep embossing mode. The steel-to-rubber embossing structure forms large and deep textured lines on the paper surface. On the one hand, it increases the paper surface gap to enhance oil and water absorption efficiency; on the other hand, it further locks the multi-layer bonded structure to prevent layer separation. Meanwhile, the machine adopts high-tension winding to make the finished roll compact and wear-resistant.

Ordinary Toilet Paper Embossing Process

Toilet paper production adopts soft point-to-point shallow embossing, which only plays a decorative and fluffy effect without increasing paper hardness. The machine uses low-tension flexible winding to ensure the paper is soft and delicate, focusing on skin-friendly comfort rather than structural strength.

3. Finished Roll Cutting & Perforation Process Difference

Kitchen Towel Cutting & Perforation

Kitchen towel rolls requiresparse and high-strength perforation. The NRC1880 automatic band saw cutter sets longer perforation spacing and deeper indentation. The purpose is to ensure the sheet is not easy to tear accidentally during use, while ensuring manual tearing is neat. The cutting standard focuses on structural firmness to adapt to frequent wiping and scrubbing operations.

Ordinary Toilet Paper Cutting & Perforation

Ordinary toilet paper adopts dense and shallow perforation with short spacing. The process design focuses on easy and quick tearing for single-time hygiene use, pursuing lightweight and easy separation performance, and appropriately reduces the tensile resistance of the single sheet.

5. Summary of NRC1880 Machine Process Switching Logic

The fundamental reason why the NRC1880 dual-purpose toilet paper machine can switch between the two production processes lies in its adjustable gluing and laminating composite system:

1. Turn on gluing & laminating + deep embossing + high-tension winding = standard kitchen towel paper production process;
2. Turn off gluing & laminating + shallow soft embossing + low-tension winding = standard ordinary toilet paper production process.

This unique one-machine dual-process design saves equipment investment for South African tissue manufacturers, realizes flexible switching of product categories, and greatly improves market competitiveness.
