Embodiment 1

[0017] A kind of processing step of the production method of low-temperature polyester fiber two-color sliver cloth is:

[0018] (1) Weaving process of low-temperature polyester fiber sliver cloth spring and summer fabric gray cloth:

[0019] Select low-temperature polyester fiber yarn 75D / 72F and cationic yarn 75D / 72F with a dyeing temperature of less than 100°C, and weave the gray fabric on a 30″28G double-sided knitting large circular machine according to the type of double-sided acrylic fabric. Among them, the upper yarn of the gray fabric is made of low-temperature Polyester fiber yarn 75D / 72F and cationic yarn 75D / 72F are arranged circularly at equal distances according to the total number of machines. The bottom yarn of the gray cloth is made of conventional polyester fiber yarn DTY75D / 72F, and the unit weight of the gray cloth is 160g / m 2 . At this time, since the two-color stripes are arranged in an equidistant cycle, the weight percentages of the low-temperature pol...

Embodiment 2

[0023] This example dyes and finishes dark purple + light purple striped cloth.

[0024] (1) Weaving process, except that the following parameters are changed, its process is the same as Example 1:

[0025] The low-temperature polyester fiber yarn is 100D / 72F, the cationic yarn is 100D / 72F, the conventional polyester fiber yarn is DTY100D / 72F, and the unit weight of gray cloth is 180g / m 2 .

[0026] (2) Dyeing and finishing process, except that following parameters change, its processing step is identical with example 1:

[0027] Gray fabric degreasing temperature is 70°C, heat preservation for 22 minutes, disperse dyes are X-GRL red 0.14kg, X-BL blue 0.05kg, cationic dyes are FB red 0.22kg, F-4R blue 0.24kg, dye auxiliaries HAC 2.0 kg, cationic leveling agent 0.6kg, anti-precipitation agent 1.0kg, the dye liquor is raised from room temperature to 97°C and kept for 50 minutes, the water temperature for reduction washing is 70°C, and the washing time is 25 minutes.

Embodiment 3

[0029] This example dyes and finishes rose red + deep purple striped cloth.

[0030] (1) Weaving process, except that the following parameters are changed, its process is the same as Example 1:

[0031] The low-temperature polyester fiber yarn is 150D / 72F, the cationic yarn is 150D / 72F, and the conventional polyester fiber yarn is DTY150D / 72F. The weight percent of arrangement is 12.5%, 37.5%, 50%, and the unit weight of gray cloth is 200g / m 2 , According to the double-faced acrylic cloth, the gray cloth is woven on a 34″28G double-faced circular knitting machine.

[0032] (2) Dyeing and finishing process, except that following parameters change, its processing step is identical with example 1:

[0033] Gray fabric degreasing temperature 80°C, heat preservation for 20 minutes, disperse dyes are R-FB red 0.57kg, B-E / 4R blue 0.006kg, cationic dyes are R-X / GRL red 0.16kg, B-X / BL blue 0.12kg, dye auxiliaries HAC 2.0kg, anti-precipitation agent 1.0kg, the dye liquor is raised fr...

Abstract

The invention relates to a method for producing low-temperature polyester fiber double-color strip fabric. By the method, the production process flow of the strip fabric is optimized, energy resources are saved to the greatest extent and the emission of carbon dioxide is reduced. The method comprises the following steps of: 1, performing a weaving process, namely weaving grey cloth on a double-sided circular knitting machine by selecting a low-temperature polyester fiber yarn and a positive ion yarn as upper face yarns and an ordinary polyester fiber yarn as a bottom face yarn according to double-sided acrylic cloth; and 2, performing dyeing and finishing processes, namely removing oil from the grey cloth, placing in a vat, throwing disperse dye stuff and positive dye stuff in a dye vat, dyeing in a bath, raising the temperature of dye liquid in the dye vat from room temperature to between 96 and 99 DEG C, preserving temperature for 40 to 60 minutes, reducing and washing for 20 to 30 minutes at the temperature of between 60 and 80 DEG C, taking the cloth out, dewatering, drying, forming and obtaining a finished product.

Description

technical field [0001] The invention relates to the technical field of production of polyester fiber two-color slivers, in particular to a production method of low-temperature polyester fiber two-color slivers. Background technique [0002] The variety of clothing fabrics makes polyester fiber fabrics more and more widely used, and more and more polyester fiber two-color strips are used as clothing fabrics. At present, there are two methods for producing polyester fiber two-color slivers: one is to use printing; the other is to use high-temperature and high-pressure dyed yarn, and then yarn-dyed. The process flow of printed stripe cloth is: pattern design→plate making→color paste preparation→polyester fiber gray cloth treatment (130℃)→printing→drying→steaming→washing→finishing and finalizing. This kind of printing process is complicated, and the pollution is very serious. It needs 130 ℃ high temperature treatment of polyester fiber gray cloth, which consumes a lot of energy...
