Problems solved by technology

[0002] At present, the conventional wet wipe base fabric generally adopts spunlace non-woven fabric blended with viscose fiber and polyester fiber, and the polyester fiber in it cannot be degraded.
In order to ensure the barrier performance and heat sealing performance, the wet wipe film is generally made of multi-layer composite materials such as PP+PET+PE, and different plastic composites cannot be recycled.

Embodiment 1

[0031] [A production process of degradable wet wipes]

[0032] The production process includes:

[0033] The first part prepares the base cloth for wet wipes, which specifically includes the following steps:

[0034] A selects raw materials, B opens, mixes and combs fibers, C cross-laps and draws, D is pre-wetted and spunlaced, and E is dried; among them,

[0035] The selected raw materials in the step A are: screening wood pulp wt 50%, 8-10mm polylactic acid staple fiber wt 15% with a fineness of 1.5 dtex, and 8-10mm lyocell staple fiber wt 15 with a fineness of 2.0 dtex % and 9mm fineness of 1.67 dtex viscose staple fiber wt20% as the raw material of non-woven fabric;

[0036] The step B of opening, mixing and carding the fibers is as follows: polylactic acid staple fibers, lyocell staple fibers and viscose staple fibers are respectively opened by separate rough opening and fine opening equipment, and carded by a carding machine, Among them, the cylinder of the carding ma...

Abstract

The invention discloses a production process of degradable wet wipes, wet wipes, and a packaging film for the wet wipes. The wet wipe base fabric of the invention adopts degradable wood pulp, polylactic acid staple fiber, Viscose staple cellulose fibers are formed by wet laying and hydroentanglement curing and drying technology, and then dipping or spraying the solution to form a wet tissue product with a certain amount of liquid. The wet tissue in the present invention is degradable. In addition, in the present invention, a double-layer PE film is also proposed for the packaging of the degradable wet wipes as its envelope. The surface layer of the double-layer film PE is biaxially stretched PE, and the inner layer is a metallocene modified PE film. Polyethylene can be recycled due to its single thermoplastic material. The present invention obtains degradable wet wipes with good mechanical properties by screening suitable cellulose fiber types and proportions, and optimizing the fiber opening and carding process; meanwhile, the packaging film used for the wet wipes meets the requirements of barrier performance and heat-sealing performance. At the same time, it can be recycled and used, which meets environmental protection requirements.

Description

technical field [0001] The invention relates to a wet tissue product and the technical field of its production, in particular to a production process for a degradable wet tissue, a wet tissue, and a packaging film for the wet tissue. Background technique [0002] At present, the conventional wet wipe base fabric generally adopts a spunlace non-woven fabric blended with viscose fiber and polyester fiber, and the polyester fiber in it cannot be degraded. In order to ensure the barrier performance and heat sealing performance, the wet wipe film is generally made of PP+PET+PE and other multi-layer composite materials, and different plastic composites cannot be recycled. With the improvement of people's living standards and the increasing awareness of environmental protection, especially the release of the "plastic ban" in various places, the development of a degradable wet wipes, including the recyclable packaging film used for the degradable wet wipes, has become a market trend...
