Embodiment 1

[0054] A kind of preparation technology of wool-like fabric, such as figure 1 shown, including the following steps:

[0055] S1, warping: Warping FDY polyester and DTY polyester respectively;

[0056] S2, warp knitting: use FDY polyester as the upper yarn and DTY polyester as the base yarn to weave a three-layer gray fabric, with DTY layers on both sides and FDY layer in the middle;

[0057] S3, cloth cutting: cut the gray cloth from the middle to obtain two semi-finished fabrics;

[0058] S4, pre-shaping: transfer the semi-finished fabric in the tunnel furnace, the heating temperature of the tunnel furnace is 220°C;

[0059] S5, modification by immersion:

[0060] S5.1 Put the pre-shaped fabric into a dye vat without dye, add pretreatment agent, soak at 80°C for 60 minutes, and dry after two dips and two rollings;

[0061] S5.2, put the pretreated fabric into a dye vat without dye, add a modifying agent, soak for 50 minutes at 90°C, adjust the pH to neutral, and then dry ...

Embodiment 2

[0070] The difference with embodiment 1 is:

[0071] In parts by weight, per 100 parts of water, the raw material components of the pretreatment agent are shown in Table 1.

[0072] In parts by weight, per 100 parts of water, the raw material components of the modified treatment agent are shown in Table 1.

Embodiment 3

[0074] The difference with embodiment 1 is:

[0075] In parts by weight, per 100 parts of water, the raw material components of the pretreatment agent are shown in Table 1.

[0076] In parts by weight, per 100 parts of water, the raw material components of the modified treatment agent are shown in Table 1.

Abstract

The invention discloses a preparation process of wool-like fabric, and relates to the technical field of artificial fur. The preparation process comprises the following steps of S1, warping; S2, warpknitting; S3, cloth cutting; S4, presetting; S5, soaking modification; S6, dyeing; and S7, after finishing; and the modified treating agent comprises the following components of, in parts by weight inevery 100 parts of water, 35-40 parts of sericin, 1-2 parts of tween 80, 8-10 parts of epichlorohydrin, 2-4 parts of sodium hydroxide, and 2-4 parts of catalyst. The main component of the sericin isamino acid, and the molecular structure of the sericin contains hydrophilic groups such as hydroxyl and carboxyl, so that the sericin has excellent moisture absorption performance. Active C-Cl bonds in epichlorohydrin molecules and amino groups in the sericin are subjected to nucleophilic substitution reaction for condensation, or the amino groups in the sericin and benzene rings in epichlorohydrin are subjected to ring-opening reaction to prepare a glue-containing epoxy compound, epichlorohydrin serves as a carrier, the sericin is grafted to polyester fibers, and the moisture absorption performance of polyester fabric is further improved.

Description

technical field [0001] The invention relates to the technical field of artificial fur, more specifically, it relates to a preparation process of a wool-like fabric. Background technique [0002] Wool fabrics have excellent warmth retention and beauty, and are widely used in blankets, clothing and various decorative materials. At present, the trend of caring for animals is increasing all over the world. At the same time, artificial fur that does not sacrifice animals has gained popularity. Great attention. [0003] The Chinese patent with publication number CN104480612A discloses a production method of an antistatic wool-like fabric, which includes the following steps: (a) weaving: using 72f semi-dull or full-dull yarn as the face yarn, 72f filament and conductive yarn blended yarn As a base yarn, the above-mentioned silk thread is woven into a gray cloth with a circular weft machine, and the conductive thread accounts for 20-30% of the total mass of the gray cloth; (b) pret...
