Abstract
The invention provides a double-component non-woven spinning and a production method thereof. The double-component non-woven spinning is produced by the following steps of: adopting triple lobe type COPET (low melting point polyester)/PET (polyethylene terephthalate) fibers as raw materials, wherein the fibers comprise the following components in percentage by weight: 15-25 percent of COPET, and 85-75 percent of PET; and carrying out polyester chipping, crystallization and drying, melt spinning, cooling, air drafting, wet forming, hot air bonding, trimming and rolling, and other processes. The double-component non-woven spinning and the production method thereof have the advantages that: hot rolling and impregnation are not needed, the process flow is optimized, the production speed is quickened, and simultaneously, the energy conservation and the consumption reduction are realized; and the product has good air permeability, good wet permeability and good stiffness, and the application range of non-woven fabrics is enlarged.
Description
Technical field
The present invention relates to the manufacturing approach of a kind of pair of component nonwoven fabric spinning, especially a kind of two component C OPET (low-melting point polyester)/PET (PET) fiber is a raw material with trilobal cross, the nonwoven fabric spinning of processing through hot blast adhesion.
Background technology
Nonwoven fabric is claimed non-weaving cloth again, or Nonwovens.Because it is a kind of need not spinning cotton and weaving cloth and the fabric that forms; Just textile staple or long filament are carried out orientation or support row at random; Forming fibre net structure, adopt machinery then, heat is sticking or method such as chemistry is reinforced and formed. non-weaving cloth has been broken through traditional weaving principle, and has that technological process is short, speed of production is fast; Characteristics such as output is high, cost is low, purposes is wide, raw material sources are many, it is widely used in industries such as medical and health industry, home decoration, rag trade, industry, agricultural.
The present domestic instance that does not also have the production PET filament non-woven fabric spinning of COPET, PET coupling; And the nonwoven fabric spinning is a raw material with one pack system staple fibre (water-soluble poval staple fibre) mainly; With the polyvinyl alcohol adhesive is that binding agent production makes, like CN1461850A soluble non-woven fabrics and preparation method thereof.
Chinese invention patent CN101525811A on September 9th, 2009 disclosed production technology be raw material with the water-soluble poval staple fibre, process through the procedure of processing of fiber shredding just, smart shredding, combing, lapping, air lay, rolling and molding, calendering, arrangement rolling, rewinding check.The nonwoven fabric of method production has good water solubility than the product among the CN1461850A thus, fugitive color distortion; Color and luster is attractive in appearance; And having cancelled with the polyvinyl alcohol adhesive in process of production is binding agent, has both reduced environmental pollution, has saved the energy and the water consumption of production process again.But because single, the complex production process of this production method raw material, cause product to have still that gas permeability is weak, deflection is bad, speed of production waits defective slowly.
And the production of traditional PET filament non-woven fabric is that single PET is cut into slices through crystallizing and drying, melt spinning, cooling forming, drawing-off, hot rolling, HEAT SETTING, dipping, rolling finished product.Its technological process is long, and speed of production is low, and cost is high.
Summary of the invention
The deficiency that exists to above-mentioned prior art, for adapting to vast production demand, the present invention aims to provide that a kind of production technology is simple and direct, speed of production is accelerated, product quality is excellent, the production method of the nonwoven fabric spinning of environmental protection and energy saving.
The two component C OPET/PET fibers of the trilobal cross that the present invention adopts, its raw materials quality percentage is: COPET is 15% ~ 25%, PET is 85% ~ 75%; Its cross section is a trilobal cross, and the leaf rib at leaf top adopts the COPET of low temperature fusing point, and the middle part is conventional PET, and three such leaf silks are to adopt the United States Patent (USP) technology to produce to obtain; Mingle mutually together when the leaf rib receives hot blast adhesion, need not the high temperature hot rolling, need not impregnation.
The two component C OPET/PET fibers of the trilobal cross that the present invention adopts make product increase than the enhancing of traditional processing technology product gas permeability, deflection.
The spinning of of the present invention pair of component nonwoven fabric is a raw material with the two component C OPET/PET fibers of trilobal cross, and its production technology comprises:
(1) polyester slice; (2) crystallizing and drying; (3) melt spinning, cooling; (4) air drawing; (5) become net; (6) hot blast adhesion; (7) side cut rolling.
Two component C OPET (water-soluble polyester)/PET (PET) fiber is a raw material with trilobal cross in the present invention; Adopt the hot blast adhesion method to produce the nonwoven fabric spinning; Compared with prior art, outstanding advantage is: the bicomponent fibers that the present invention adopts becomes silk speed fast, becomes net spee fast; Need not the high temperature hot rolling in the production process, need not impregnation, the optimization production flow process shortens the production time; The nonwoven fabric spinning product good permeability of producing, deflection is good.
