Abstract
The invention discloses a masterbatch used for manufacturing PPT (polytrimethylene terephthalate) fiber. The weight percentages of all components of the masterbatch are that: 65 to 80 percent of resin carrier and 20 to 35 percent of paint. The manufacturing method includes the steps: (1) PPT polymers are smashed and ground into powder; (2) the paint is infiltrated and dispersed and then is equally and thoroughly mixed with the powder of PPT polymers obtained from the step (1); (3) the mixed powder obtained from the step (2) is cut, fused, dispersed and homogenized through a double-screw fusing-extruding machine specially used for the masterbatch, and finally grains are extruded out from the machine to get the masterbatch. The application of the masterbatch is that: the masterbatch can be added according to the proportion of 1.0 to 4.0 wt percent into PPT slices for blending and spinning. The PPT fiber is characterized in that the spinnability is better; the color of fiber is equal without color difference or colored patches; the capability of the fiber is excellent, etc.
Description
Technical field
Dye technology field before the present invention relates to fiber and spinning relates in particular to a kind of Masterbatch of producing the polytrimethylene terephthalate black fiber and its production and application that is used to.
Background technology
Polytrimethylene terephthalate is the emerging a kind of macromolecular material that grows up of 21st century, this kind fiber combines the flexibility (and better look is spent always) of nylon, the bulkiness (and having avoided liability fraying) of acrylic fibers and the pollution resistance (good feel is arranged) of terylene, add intrinsic superior elasticity and elastic recovery itself, the excellent wearability of various fibers is integrated in one, fast-developingly in recent years becomes that tool is used and the synthetic fiber of DEVELOPMENT PROSPECT.
Though the polytrimethylene terephthalate fiber can boiling dyeing at normal pressure, the dye level of dye level, particularly dark series of products, also there is deficiency at present in aspects such as look old degree.The manufacture method of also coloured polytrimethylene terephthalate fiber in the prior art, patent as publication number CN 1766185A, introduced a kind of production method of coloured polytrimethylene terephthalate staple fibre, but be not specifically related to the concrete prescription and the manufacturing processing technic of color grain, in implementation also lay special stress on must adopt the defective of the temperature that differs lower more than 10 ℃ when using this kind method to produce the look silk.The patent of publication number CN 101168860A has also been delivered a kind of preceding painted coloured PTT memory fiber that spins, set forth a kind of technology of the terylene look silk that follows conventional lines, the method that adopts the addition manner of Masterbatch to produce coloured polytrimethylene terephthalate fiber does not relate to the prescription and the technology characteristics of coloured polytrimethylene terephthalate master batch.
Because the hot property of polytrimethylene terephthalate is poor than PET, polymer is easy to generate thermal degradation, in the master batch process, on the one hand owing to added pigment or various dispersants of dye well and auxiliary agent, the mixed melting process of master batch processing causes the degraded of polymer support on the other hand, make that the coloured polytrimethylene terephthalate master batch viscosity that makes is low, fusing point is low, and is poor with the spinnability of polytrimethylene terephthalate blend, also occurs problems such as color spot easily.For this reason, some master batch manufacturers select polybutylene terephthalate (PBT) or other copolyester with low melting point to produce the color grain of polytrimethylene terephthalate as the master batch carrier at present, this to a certain degree can influence the compatible uniformity of both blend, also can have influence on final fiber intrinsic some performance indications and application characteristic.
