Description
Technical field
The present invention relates to a kind of used for textiles compound silk, specially refer to a kind of terylene CATION extraordinary splendor compound silk and manufacturing approach thereof.Belonging to the chemical fibre field, is a kind of differential long filament, specifically a kind of CATION extraordinary splendor compound silk that is used for textiles.
Background technology
Polyester FDY (fullly drawn yarn (FDY)), POY (pre-oriented yarn) compound silk ITY (Intermingled textured yarn) are that a kind of feel is better, and crease resistance is excellent washs/wash compound silk, are mainly used in weaving process such as water spray, jet, circular knitting machine.
The manufacturing technique of ITY compound silk has two kinds: a kind of is the two-step method production that Chinese invention patent 201110263638.0 " the flat production method of leading the ITY silk of terylene " is introduced; Another kind of is the ITY one-step method production process that Chinese invention patent 200710301714.6 " one-step method is made the method and the device of full-drawn yarn/yarn/pre-oriented yarn stranding composite yarn " and Chinese invention patent 200610103920.1 " a kind of polyester fondant POY, FDY compound silk spinning process " are introduced.
Two-step method is to produce this plying network yarn by the process route that FDY and POY plying are incorporated into the power networks; The process route of producing like this is because of its production process route is long, the technology controlling and process link is many, and this plying network yarn energy resource consumption of production is big, cost is high, quality is unstable thereby cause.One-step method adopts spinning, traction, Split Down, network once moulding on a production equipment; This method technological process is short, and energy resource consumption is low, steady quality; But this method is FDY, the POY compound silk of normal polyester, can effectively not embody the double-colored extraordinary splendor effect of ITY.
Summary of the invention
The objective of the invention is a kind of terylene CATION extraordinary splendor compound silk of designing for the deficiency that solves ITY dyeing and finishing aspect in the prior art, can on the source, solve the problem of terylene ITY dyeing difficulty, beautify cloth, improve the cloth quality.Another object of the present invention provides a kind of manufacturing approach of above-mentioned terylene CATION extraordinary splendor compound silk.Method of the present invention is in the advantage that keeps the one step processing process flow, and short like flow process, energy resource consumption is low, beyond the steady quality etc., can also effectively embody the double-colored extraordinary splendor effect of ITY.
Technical solution of the present invention is: a kind of terylene CATION extraordinary splendor compound silk; Adopt two kinds of man-to-man being composited of different tow, it is characterized in that, said two kinds of different tow; Be respectively: FDY adopts the cationic polyester slice spinning, and POY adopts the normal polyester slice spinning; Perhaps FDY adopts the normal polyester slice spinning, and POY adopts the CATION slice spinning.
Because of two kinds of silks have the different dyeing performance, be mainly reflected in the otherness of ingrain and the otherness of thermal contraction, when presenting various colors through after the dyeing and finishing.
In the prioritization scheme of the present invention:
Said FDY fiber number is 15-100dtex, monofilament radical 13-70f; Said POY fiber number is 15-100dtex, and the monofilament radical is 17-80f.
