Problems solved by technology

[0002] The traditional technology of raising agent and penetrating agent needs to be dried and pre-shaped at a temperature of about 200°C after being loaded on the gray cloth to achieve the effect. The process consumes a lot of energy and the production cost is high.
Among them, conventional penetrants are not washable and must be dried to achieve the effect

Embodiment 1

[0035] A one-bath dyeing one-bath method for warp knitted fleece fabrics omits a pre-shaped feeding process, and the process comprises the following steps:

[0036] (1) Weaving of the white blank: choose the warp knitted fleece made of pure polyester chemical fiber as the white blank (28 needles). During the weaving of grey fabrics, the weaving loops are adjusted by adjusting the bottom yarn and the veil. Taking the production of elastic fleece as an example, the existing process parameters before adjustment were 2480mm / R for veil and 1430mm / R for bottom yarn. Now it is required to loosen the coils during production, and the parameters are changed to: 2490mm / R for veil and 1485mm / R for bottom yarn. mm / R is the unit of the yarn feed amount of the blank length.

[0037] (2) Dyeing of warp knitted woolen cloth: put the white blank into the high temperature and high pressure overflow dyeing machine, add SP-083 penetrant → 717E refining agent → RS-8 leveling agent → pH adjuster an...

Embodiment 2

[0046] A process for producing flannel by dyeing one-bath method of warp knitted fleece cloth, the process comprises the following steps:

[0047](1) Weaving of the white blank: choose the warp knitted fleece woven from pure polyester chemical fiber as the white blank. During the weaving of grey fabrics, the weaving loops are adjusted by adjusting the bottom yarn and the veil. Taking the production of elastic fleece as an example, the existing process parameters before adjustment were 2480mm / R for veil and 1430mm / R for bottom yarn. Now it is required to loosen the coils during production, and the parameters are changed to: 2490mm / R for veil and 1485mm / R for bottom yarn. mm / R is the unit of the yarn feed amount of the blank length.

[0048] (2) Dyeing of warp knitted woolen cloth: put the white blank into the high temperature and high pressure overflow dyeing machine, add SP-083 penetrant → 717E refining agent → RS-8 leveling agent → pH adjuster and dyes of corresponding color...

Embodiment 3

[0061] A process for producing flannel by dyeing one-bath method for warp knitted fleece cloth, the specific steps of the process are the same as those in Example 2, the difference is: the rolling liquid is composed of the following raw materials in mass fractions: sulfated castor oil 0.008%, alkane succinate Sodium sulfonate 0.012%, hydroxy silicone oil emulsion 0.02%, coconut oil fatty acid diethanolamide 0.01%, glacial acetic acid 0.001%, and the balance is water. Using the brushing process of this embodiment, the thickness of the grey cloth reaches 85-90 filaments, and the raising effect is good.

[0062] The techniques of the above embodiments have achieved:

[0063] 1. Raising effect: Through the adjustment of the weaving coil, the raising effect can be achieved by wet drawing process without raising agent;

[0064] 2. By adjusting the effect of the penetrant with clear water, the penetrant is added to the same bath for dyeing under the condition of washing resistance, ...

Abstract

The invention relates to a dyeing method, and particularly relates to a warp-knitting terry fabric dyeing-bath preshaping-omitted charging process. The process comprises the following steps: (1) whitebody weaving, to be more specific, according to different styles of customer products, selecting different yarns and different coils for weaving to obtain a white body before dyeing; and (2) warp-knitting terry fabric dyeing, to be more specific, putting the white body into a high temperature high pressure overflow dyeing machine, sequentially adding a penetrant, a refining agent, a leveling agent, a pH regulator and a dye, adding water for mixing to obtain a dying liquid; and heating a dye vat to 130-140 DEG C, holding for 30-40 minutes to complete the warp-knitting terry fabric dyeing-bathpreshaping-omitted charging process.

Description

technical field [0001] The invention relates to a dyeing and finishing method, in particular to a one-bath dyeing method for warp knitted fleece fabrics, which omits the pre-shaped feeding process. Background technique [0002] Raising agent and penetrating agent in the traditional process can only achieve the effect by drying and presetting at a temperature of about 200 ℃ after the grey fabric is loaded, and the process energy consumption is high and the production cost is high. Among them, conventional penetrants are not resistant to washing and must be dried to achieve the effect. SUMMARY OF THE INVENTION [0003] The invention mainly solves the deficiencies in the existing traditional technology, replaces the traditional high-temperature pre-formed feeding process, thereby achieving energy saving and consumption reduction, improving production efficiency and reducing production cost. The method of pre-type feeding is omitted. [0004] The technical scheme adopted by ...
