Embodiment Construction

[0024] Before introducing the present invention, we should at first understand the fiber cotton production technology, and fiber cotton production mostly adopts glued cotton process or hot-melt cotton process, and these two processes are different.

[0025] Spray-bonded cotton is made of ordinary fibers using glue or surface layer netting to bond the surface structure. For example, the production process of spray-bonded cotton made of polyester (PET) fibers usually needs to go through a bale opener, a cotton opener, and an opening machine. After that, it is sent to the cotton feeder, and then combed into a thin layer by a carding machine, that is, the fibers are distributed in two dimensions, and then the polyester (PET) fiber layer in a two-dimensional distribution is folded with a forming machine It is made into the required thickness, sprayed with adhesive, and combined with layers of fibers, and dried.

[0026] The hot-melt cotton process uses the low-melting point composi...

Abstract

The invention discloses a cellucotton pad and a preparation process thereof and particularly relates to a preparation process for preparing a cellucotton pad from low-melting-point fibers and plant fibers serving as main raw materials by means of mixed heat treatment and the cellucotton pad prepared by the process. The preparation process includes: preparing, based on the total weight of the fiber raw materials, 5%-85% of the low-melting-point fibers and 15%-95% of the plant fibers or renewable fibers into the raw materials sequentially by weighing, compounding, coarse opening, fine opening, netting, heat bonding sizing and sizing so that a bended cellucotton block is prepared, wherein a chemical cellucotton layer is adhered on the periphery of the cellucotton block. The cellucotton pad and the preparation process have the advantages that the problems of broken layer shedding and the like due to the fact that the plant fibers and the renewable fibers substitute for most of chemical fibers in the prior art are well solved, infestation of external bacteria and pest and disease damage is isolated, uncomfortableness caused by prickle of crude fibers such as the plant fibers is also avoided, raw material selection range is wide, and a great quantity of resources are saved effectively.

Description

Technical field [0001] The present invention relates to a kind of fiber cotton pad preparation technology, specifically, the present invention relates to a kind of preparation technology of fiber cotton pad by adopting low-melting point fiber (hot-melt fiber) and plant fiber mixed heat treatment as main raw material to prepare fiber cotton pad, the present invention also relates to Fiber cotton pads produced using this process. Background technique [0002] Fiber cotton products produced by chemical synthetic fibers have been widely used in mattresses, sofas and other household items, car seat cushions, sound-absorbing and heat-insulating materials for buildings, and industrial air pre-filtering and industrial filter material insulation materials. However, due to the existing The widely used synthetic fibers using by-products in the petrochemical industry and coking industry are expensive, limited in resources, and are facing the threat of depletion of petroleum and coal res...
