[0004] In the textile factory, a large amount of short fibers will be scattered on the ground during the process of spinning various fiber materials such as cotton yarn into threads. It is difficult for these scattered short fibers to be used for spinning again after cleaning. The general treatment is to dispose of them Discarding not only increases the production cost, but also causes a waste of resources

Embodiment 1
[0025] A kind of environment-friendly cardboard formula that utilizes papermaking sludge and textile fiber waste to regenerate, by weight percentage, consists of the following components:
[0026] Paper sludge 70%
[0027] Textile fiber waste 30%
[0028] Among them, the moisture content of the papermaking sludge is 85%, and the fiber length of the textile fiber waste is 5-7 mm, and the diameter is 0.001-0.002 mm. The lightness of the 2cm thick cardboard produced is only 0.25Kg / m 2 , good impact resistance, good sound absorption and heat insulation.

Abstract
The invention belongs to the technical field of environment-friendly paperboard, in particular relates to a formulation of environment-friendly paperboard regenerated by papermaking sludge and waste textile fibre material. The formulation comprises the following components by weight percentage: 70-95% of papermaking sludge and 5-30% of waste textile fibre material, the water content of the papermaking sludge is 85-95%, the content of long fibre is less than 30%, the length of the fibre in the waste textile fibre material is 5-15mm and the diameter thereof is 0.001-0.01mm. The papermaking sludge is the papermaking sewage from paper industry and used as one raw material of the invention, and the waste textile fibre material is mainly from the waste fibre of spinning mills and used as the other raw material of the invention, so as to change the waste into the valuable. The prepared paperboard has light weight, good shock resistance, good sound absorption effect and heat insulation effect. The invention not only saves social resources, but also protects the ecological environment, and solves the big problems of the paper industry and the textile industry. The formulation is a new technique with environmental benefit, economic benefit and social benefit.
Description
Technical field: [0001] The invention belongs to the technical field of environment-friendly cardboard, in particular to an environment-friendly cardboard formula regenerated by utilizing papermaking sludge and textile fiber waste. Background technique: [0002] In the papermaking industry, the pollution of papermaking sewage has always been one of the main pollution sources of environmental protection. It is reported that my country's papermaking volume reached 38 million to 40 million tons in 2005. In 2005, the national total consumption of paper and paper products will reach 50 million tons, and the total pollution will reach 3.6 billion tons per year. How should we deal with and control such a large amount of pollution, so as to minimize the total investment in pollution control? , Recycling and recycling, and taking the path of sustainable development have always been the guidelines we advocate. The papermaking sewage is turned into papermaking sludge after physical an...
