Problems solved by technology
[0003] The existing full-cure products are not thorough enough to remove impurities, which will cause the finished products to be heavy and contain more impurities, and the toughness of waste materials when they are reused is too poor, and the service life will be greatly shortened, so While causing environmental pollution, it also affects the service life of the finished products produced

Embodiment Construction
[0018] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0019] The present invention provides a kind of preliminary molding process of fully solidified felt, and its steps are as follows:
[0020] First loosening: Put the waste fiber group into the loosening machine for loosening; this can remove the impurities in the waste fiber, promote more uniform cotton production in the later stage, and make cotton production easier, saving the time for cotton production. Steam: transfer the aforementioned loosened materials to a steam device for steam blowing, and the time is 0.5 to 1 hour, and the wind speed is 1 to 1.5m / s; in this way, the waste fiber can be steam sterilized and softene...

The invention provides a process for preliminarily molding an all-solid-state felt. The process for preliminarily molding the all-solid-state felt comprises steps: primary slackening, steam blowing, hot dry air blowing, secondary slackening, cotton carding, adhesive spraying, spraying and heating. The process for preliminarily molding the all-solid-state felt can clear away impurities in waste fibers, prevents static electricity from producing to affect quality of products during the production process of the products, also prevents the products from fluffing simultaneously, and more promotes adhesive to permeate by forming a layer of protective layer on the surface of the adhesive, thereby enabling formed cotton to be more uniform, being easy to form cotton, and saving cotton forming time.
Description
technical field [0001] The invention relates to the field of felt production, in particular to a preliminary molding process of a fully cured felt. Background technique [0002] my country is a big country that produces and uses fibers. It produces and imports a large amount of various fibers every year, among which polyester fiber consumes the most, accounting for about 35% of the market. The total fiber consumption in my country exceeds 10 million tons every year. The amount of leftover waste of textiles and old clothes is very considerable. If they are discarded, it will not only cause huge waste, but also cause pollution to the environment. Reasonable use of these materials not only solves the pressure of environmental protection, but also can be made into high value-added products such as porous materials for automotive interior decoration. [0003] The existing full-cure products are not thorough enough to remove impurities, which will cause the finished products to b...
