Embodiment Construction

[0032] Before introducing the present invention, we should first understand the production technology of fiber cotton hot-melt cotton process. This process utilizes the fiber cortex of low-melting point composite short fiber to have low-temperature melting performance, and melts at a low temperature of 110-180 degrees (some products are melted at 100 or Fibers that can be melted and bonded under dry heat conditions of 120 degrees Celsius, while the melting point of ordinary polyester staple fibers is above 255 degrees), the melted peripheral part is like glue, bonded with other fibers, and has the function of an adhesive. There are many types of low-melting fiber, including LMF (4080 low-melting fiber), low-melting polyolefin thermal bonding fiber, low-melting fiber produced by polyester composite spinning, low-melting polyester, polypropylene, and polyamide thermal bonding. Melt glue, random copolymerized modified polyester with low melting point, etc. Two or more specially p...

Abstract

The invention discloses a fiber cotton cushion and preparation process thereof and particularly relates to preparation process for preparing a fiber cotton cushion and the fiber cotton cushion manufactured according to the preparation process, wherein main raw materials are formed by blending heat treatment of low melting point fibers and other fibers. A cellucotton block manufactured according to hot melt cotton preparation process is slit into a plurality of cellucotton sub-blocks, the cellucotton sub-blocks are placed and attached side by side, or cellucotton blocks or a cellucotton block are or is laid on the upper face and the lower face or one of the faces after the process of attaching, then attaching forming is carried out through a heat bonding device, and the fiber cotton cushion is manufactured. According to the fiber cotton cushion and the preparation process thereof, the synthetic cellucotton block manufactured by heat bonding forming and slitting is slit and recombined, the fiber cotton cushion can be adjusted and controlled according to needs, in addition, density, fiber upright degree and surface evenness can be adjusted and controlled according to needs, then hot melting forming process is carried out, and quality of the fiber cotton cushion can be greatly improved.

Description

Technical field [0001] The present invention relates to a kind of fiber cotton pad and preparation technology thereof, 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 other fiber mixing heat treatment as main raw material to prepare fiber cotton pad, the present invention It 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 products, car seat cushions, sound-absorbing and heat-insulating materials for buildings, and industrial air pre-filtering and industrial filter materials for thermal insulation materials and other fields. We know that the production of fiber cotton mainly adopts the spray-bonded cotton process or the hot-melt cotton process, and these two processes are different. [0003] Spray glued...
