Abstract

One kind of short flame-resistant viscose fiber: the raw material and percent by weight are: Cellulose filament 66.7-76.9%, flame-resistant 15-20%, aqueous8-13%, oil emulsion 0.10-0.30%. With the technique of fermenting , soaking, squeezing, smashing, experienced, alkali filament cooling and transportation, etiolution, dissolution, filtration, ripening, deaeration, filtration, spins inpouring, spinning, two baths, one draft, two drafts, three roller beaming, cutting-off, concise (rough steam boiling, sour laundering, one laundering, desulphurization, two laundering, blanching, three and four laundering and PH value regulation, oil bath), drying( wet pine, wet drying delivers, A section drying, blooms pine, B section drying, dry delivery), fine blooms pine, packing, the system results in the non-toxic environmental protect, non spontaneous combustion, non burning without flames, evacuation extinguished without fire hazard, and low burning smoking density. It has good spinnability, stable permanent being flame-resistant, fine soft performance.

Description

technical field [0001] The invention relates to a flame-retardant viscose staple fiber used as a raw material in the non-woven industry and the textile industry and a production method thereof, in particular to a flame-retardant viscose staple fiber used in the non-woven industry and the textile industry and a production process thereof. Background technique [0002] Ordinary viscose staple fiber has been developed for about 100 years. Its quality index requirements and inspection methods can be found in the GB / T14463-1993 "Viscose staple fiber" standard. It is not flame-retardant and can only be used in the traditional ordinary textile industry. Flame-retardant fibers are generally used in special operating environments and household items, as clothing, decoration, industrial fabrics, etc. It is mainly divided into two categories, one is permanent flame retardant fiber, currently more permanent flame retardant polyester fiber, although the flame retardant performance is goo...
