Problems solved by technology

[0002] At present, the disposal of waste fabrics has become an important issue for environmental protection every year. In Shanghai alone, about 100,000 tons of clothes are discarded every year. With the development of the economy, this number will continue to rise. Cotton, etc., and most of them have been incinerated, causing environmental pollution and waste of resources; on the other hand, with economic development, the demand for plates in my country has shown a substantial increase, reaching 76 million cubic meters in 2013
At present, in the process of making fiberboard by mixing waste fabrics and ES fibers, the ES fiber consumption is more than 30%, which increases the cost and reduces the consumption of waste fabrics. In addition, the fiber web needs to be needled in the prior art, Cannot manufacture thick fiberboard

Embodiment 1

[0029] A kind of manufacturing process of regenerated fiber board, comprises the steps:

[0030] (1) Crushing and opening: First, the waste fabrics are broken into cloth pieces of about 5cm×10cm. The waste fabrics include: polyester, cotton fiber, wool, nylon, polypropylene fiber, polyester fiber viscose fiber, spandex, silk, etc. Sorting to remove non-fabric foreign matter, and then opening the cloth to obtain recycled staple fibers;

[0031] (2) Opening and mixing: 1-10 parts of ES fiber and 100 parts of regenerated staple fiber obtained in step (1) are respectively opened, and then rough opening, cotton blending, and fine opening are carried out successively to obtain fully mixed and loosened fibers. Completely blended fibers, low consumption of ES fibers, saving costs and increasing the consumption of waste fabrics;

[0032] (3) Carding into a web: the mixed fibers obtained in step (2) are clustered into a continuous cotton net, and then repeatedly carded, the fibers are ...

[0037] A kind of manufacturing process of regenerated fiber board, comprises the steps:

[0038] (1) Crushing and opening: waste fabrics are first broken into 5cm×10cm pieces of cloth through a crusher, and the waste fabrics include: polyester, cotton fiber, wool, nylon, polypropylene fiber, polyester fiber viscose fiber, spandex, silk, etc. , sorting and removing foreign matter such as buttons, and then use a flowering machine to open the cloth to obtain recycled staple fibers;

[0039] (2) Opening and mixing: 1 part of ES fiber and 100 parts of regenerated staple fiber obtained in step (1) are respectively opened with a bale opener. The chartered machine performs rough opening, and then goes through large warehouse blending and fine opening to obtain fully mixed and completely opened mixed fibers. The consumption of ES fibers is low, which saves costs and increases the consumption of waste fabrics;

[0040] (3) Carding into a web: the mixed fibers obtained in step (2) are s...

Abstract

The invention discloses a manufacturing process of a regenerate fiber board. The manufacturing process of the regenerate fiber board includes following steps of breaking and fiber splitting, opening and mixing, carding and net formation, segmented heating, hot rolling and cold rolling. The regenerate fiber board is prepared from raw materials of 1-10 parts of ES fibers and 100 parts of regenerate fibers obtained by opening waste fibers. According to the manufacturing process of the regenerate fiber board, a needling technology is not used, a multilayer fiber net is heated at temperature segments, an upper and lower clamping mode is adopted in the upper half segment, the fiber net is clamped in an environment at temperature of 100-150 degree centigrade, the ES fibers mixed in the multilayer fiber net are fused, circulating hot air along the vertical direction is used to heat the multilayer fiber net at the rear segment, blast capacity below the multilayer fiber net is larger than blast capacity above the multilayer fiber net, temperature is controlled to range from 200 degree centigrade to 250 degree centigrade, chemical fiber ingredients in the multilayer fiber net are fused, and then a fused fiber net is obtained. The manufacturing process of the regenerate fiber board saves cost, simplifies working processes, reduces energy consumption, and can obtain the regenerate fiber boards good in performance and different in thickness.

technical field [0001] The invention relates to the field of building materials, in particular to a manufacturing process of regenerated fiberboards. Background technique [0002] At present, the disposal of waste fabrics has become an important issue for environmental protection every year. In Shanghai alone, about 100,000 tons of clothes are discarded every year. With the development of the economy, this number will continue to rise. Cotton, etc., and most of them have been incinerated, causing environmental pollution and waste of resources; on the other hand, with economic development, the demand for panels in my country has shown a substantial growth trend, reaching 76 million cubic meters in 2013. At present, in the process of making fiberboard by mixing waste fabrics and ES fibers, the ES fiber consumption is more than 30%, which increases the cost and reduces the consumption of waste fabrics.
