For the blended fiber dyeing of PTT fiber and cellulose fiber, the prior art needs to use two kinds of dyestuffs, disperse dye and reactive dye, to over-dye the two kinds of fibers respectively. At present, there is no literature report on the one-bath dyeing method of PTT fiber and cellulose fiber.

[0025] Color number: P016 navy blue, dyeing equipment: Jet hank dyeing machine
[0026] 1. Pre-treatment: first add the auxiliary agent in the dye bath, then raise it to 60°C at a speed of 2°C / min, keep it warm for 10 minutes, then raise it to 95°C at a speed of 1.5°C / min, keep it warm for 30 minutes, and then cool down. wash. Described auxiliary agent is by the scouring agent (Humectol LYS) of 1.5 gram / liter, the penetration agent (JFC) of 1.5 gram / liter, the hydrogenperoxide of 4 mol / liter and the oxygen drift stabilizer (Stabilizer FCB) of 0.4 mol / liter and The balance consists of water.
[0027] 2. Dyeing PTT fiber: Put the pretreated blended yarn into the jet-type skein dyeing machine, add 2.0% by weight of disperse blue SE-3RT, 1.0% by weight of disperse blue HGL, and 0.5 g / L of auxiliary dyeing Carrier (Dilatin POE), 1.0 g / L penetratin...
[0038] Pretreatment, reduction cleaning, neutralizationwater washing and aftertreatment are the same as in Example 1.
[0039] The PTT dye formula is 0.6% by weight (OWF) of Disperse Red ACE, and 0.1% by weight (OWF) of Disperse Scarlet 3G-FS.
[0040] Cotton fiber dyeing formula is 1.2% by weight (OWF) of reactive red M-2B, 1.5% by weight (OWF) of reactive red M-2BZ.
[0041] Dyeing quality index: After the blended fiber skein is dyed and finished by the above process, the product feels soft and elastic, and the color fastness index meets the requirements of the national standard for superior products. The specific properties are shown in Table 2.

Abstract
The invention discloses PTT and cellulose fibers one bath process dyeing method. It includes the following steps: adding dyeing assisted carrier into the bath; dying PTT fiber by disperse dyes; adding auxiliary agent to do reduction clearing; removing loose color; adding activated dye and auxiliary agent to dye cellulosefiber; soaping; washing; and fixing by fixing agent; mellowing; dehydrating; and drying. The invention solves the problem of blending PTT and protein fibers low temperature one bath process dyeing, and the production problem of no corresponding high temperature pressure dyeing device for enterprise, which is the key of deep processing for blending fiber product, the necessary condition for its market popularization and application.
Description
1. Technical field [0001] The invention relates to a one-bath dyeing technology of PTT fiber and cellulose fiber, belonging to the technical field of textile fiber dyeing and processing. 2. Background technology [0002] PTT fiber is polytrimethylene terephthalate, which is obtained by esterification and polycondensation of terephthalic acid (PTA) and 1,3-propylene glycol (PDO). PTT is a new product developed in recent years in the polyester family. PTT fiber combines the elasticity, wear resistance and good fatigue resistance of nylon; the bulkiness, softness, good dyeability and excellent color fastness of acrylic; the wrinkle resistance, dimensional stability and good color fastness of polyester Excellent heat resistance and other advantages, has broad application prospects. PTT polyester fiber is a kind of hydrophobic chemical fiber. Its dyeing performance is similar to that of PET polyester fiber. The dyeing temperature is lower than that of PET polyester fiber. It is ...
