Problems solved by technology

[0008] The newly developed suede fabrics on the market have excellent wool-like effects, but due to lack of better dyeing and finishing development, they often cannot overcome the shortcomings of polyester fibers:
[0009] 1) The air permeability is poor, and the moisture absorption and perspiration effect is incomparable with natural fibers;
[0010] 2) Poor antistatic effect;
[0011] 3) Poor color fastness cannot meet the clothing requirements;
[0012] 4) The hand feel is not soft enough
[0013] Most sea-island silk suede fabrics on the market are more used for decorative fabrics such as: sofas, shoe uppers, bags, etc., which limits the application in clothing

Embodiment 1

[0047] The preparation method of imitation suede fabric comprises the steps:

[0048] Step one, desizing:

[0049] The obtained polyester sea-island yarn is placed in a desizing agent for desizing to obtain a desizing gray cloth; the desizing agent includes the following components in terms of water volume: 0.5 g / L of NaOH, 0.3 g / L of benzyl alcohol, and 5 g of triethanolamine / L.

[0050] Step 2. Alkali weight reduction and fiber opening:

[0051] The desized gray cloth obtained in step 2 is opened by an overflow dyeing machine to obtain the opened fiber gray cloth; the auxiliary agent during the alkali weight reduction and fiber opening is NaOH 5g / L according to the water volume, the temperature is 110 ° C, and the time is 30 ~90min.

[0052] Step 3. Pre-ordering:

[0053] The pre-formed gray cloth obtained in step 2 is subjected to pre-setting treatment to obtain pre-shaped gray cloth; the temperature during pre-setting is 180° C., and the vehicle speed is 40 yards / min....

Embodiment 2

[0063] The preparation method of imitation suede fabric comprises the steps:

[0064] Step one, desizing:

[0065] The obtained polyester sea-island yarn is placed in a desizing agent for desizing to obtain a desizing gray cloth; the desizing agent includes the following components in terms of water volume: 0.6 g / L of NaOH, 0.4 g / L of benzyl alcohol, and 6 g of triethanolamine / L.

[0066] Step 2. Alkali weight reduction and fiber opening:

[0067] The desized gray cloth obtained in step 2 is opened by an overflow dyeing machine to obtain the opened fiber gray cloth; the auxiliary agent for alkali weight reduction and fiber opening is NaOH 6g / L based on water volume, the temperature is 112°C, and the time is 40min .

[0068] Step 3. Pre-ordering:

[0069] The pre-formed gray cloth obtained in step 2 was subjected to pre-setting treatment to obtain pre-shaped gray cloth; the temperature during pre-setting was 182° C., and the vehicle speed was 42 yards / min.

[0070] Step f...

Embodiment 3

[0079] The preparation method of imitation suede fabric comprises the steps:

[0080] Step one, desizing:

[0081] The obtained polyester sea-island yarn is placed in a desizing agent for desizing to obtain a desizing gray cloth; the desizing agent includes the following components in terms of water volume: 0.9 g / L of NaOH, 0.6 g / L of benzyl alcohol, and 8 g of triethanolamine / L.

[0082] Step 2. Alkali weight reduction and fiber opening:

[0083] The desized gray cloth obtained in step 2 is opened by an overflow dyeing machine to obtain the opened fiber gray cloth; the auxiliary agent for the alkali weight reduction and fiber opening is NaOH 12g / L based on the water volume, the temperature is 118°C, and the time is 80min .

[0084] Step 3. Pre-ordering:

[0085] The pre-formed gray cloth obtained in step 2 was subjected to pre-setting treatment to obtain pre-shaped gray cloth; the temperature during pre-setting was 188° C., and the vehicle speed was 48 yards / min.

Abstract

The invention discloses a preparing method of a chamois-imitation fabric, and belongs to the technical field of fabrics. The preparing method includes the following step of conducting desizing, alkali-peeling splitting, presetting, sanding, dyeing and postprocessing to obtain a polyester sea-island filament gray fabric so as to prepare the chamois-imitation fabric. The prepared chamois-imitation fabric is wide in application range, good in moisture absorption and sweat releasing performance, excellent in antistatic effect, high in softness and excellent in color fastness.

Description

technical field [0001] The invention belongs to the technical field of fabrics, and in particular relates to a method for preparing suede-like fabrics. Background technique [0002] Imitation suede (fǎng jǐ pí, English name suedette) in the textile industry refers to imitation suede hair style fabrics as imitation suede or imitation suede. However, in the textile industry, it is generally used to call suede or suede directly as suede. Suede can be divided into knitted and woven. Knitted suede is divided into warp-knitted suede (more common) and weft-knitted suede, and woven suede is divided into warp-knitted suede and weft-wise suede. [0003] Due to the demand for high-grade suede-like fabrics, sea-island silk suede-like fabrics came into being. Sea-island silk is a new type of composite fiber developed in recent years. The inner island of the fiber is composed of ultra-fine polyester, and the outer seawater-soluble polyester fiber is wrapped. During dyeing and finishing...
