Embodiment 1

[0044] A kind of preparation technology of blended wool fabric, such as figure 1 shown, including the following steps:

[0045] S1, combined wool: wool, FDY polyester filament and acrylic fiber are evenly mixed by a combined wool machine to obtain wool tops, in which wool accounts for 60%, FDY polyester filament and acrylic fiber account for 20% respectively;

[0046] S2, preparing gray cloth: using a weft knitting machine to weave wool tops and TDY polyester filaments to obtain gray cloth;

[0047] S3, soaking modification: put the gray cloth into a dyeing vat without dye, put in hydrogen peroxide (15ml / L), sodium silicate (1g / L), fatty alcohol polyoxyethylene ether (1g / (L)) at 45-50°C Soak for 50-60 minutes under the same conditions, wash and dry, use low-temperature plasma equipment with a discharge frequency of 13.7MHz to treat the fabric, put it into another dye vat without dye, and put chitosan (3g / L) and acetic acid ( 0.1mol / L) solution at 40-45°C for 80-90min, the ba...

Abstract

The invention discloses a preparation process of a blended wool fabric, which relates to a preparation process of fur. The preparation process of the blended wool fabric comprises the following steps:S1, wool mixing: using a wool mixing machine to mix wool, FDY polyester filament yarns and acrylic fibers evenly to obtain wool tops; S2, grey cloth preparing: using a weft knitting machine to knit the tops and TDY polyester filament yarns to obtain a grey cloth; S3, soaking and modifying: putting the grey cloth into a dyeing tank without dyestuff and putting an anti-shrinkage agent to soak; S4,dyeing: putting the grey cloth into the dyeing tank, adding the dyestuff, performing dip dyeing at 120 to 130 degrees centigrade for 30 to 80 min, and drying; and S5, finishing: brushing and buffing the fabric. The FDY polyester filament yarns, acrylic fibers and wool fibers have high similarity; and through adding the two types of chemical fibers, the overall similarity can be high, and the goodperformance is ensured, so that the dosage of wool is reduced. Then through dyeing and finishing, the consistency among wool, FDY polyester filament yarns and acrylic fibers is further improved, and the overall sensory effect of the fabric is improved.

Description

technical field [0001] The invention relates to the field of fur preparation, more specifically, it relates to a preparation process of a blended wool fabric. Background technique [0002] Wool has always been loved by consumers, but wool is expensive and its annual output is very limited. Acrylic fiber is widely used in clothing, decoration and other fields because of its wool-like appearance and low cost. [0003] The Chinese patent publication number CN107956015A discloses a blended yarn containing wool. The raw materials include 6-8% wool, 20-40% acrylic fiber, 15-25% Persian fiber and the balance by weight. nylon. The specific preparation method includes the following steps: (1) The wool raw materials are sprayed with an antistatic agent and water in a ratio of 1:10, and after spraying, they are sealed in plastic bags and left for more than 24 hours before they can be put into use; (2) Bleeding In the process, the processed wool and the acrylic fibers that do not need...
