Problems solved by technology

However, first of all, the cloth processing machine is expensive and the production cost is high; secondly, the cloth processing machine is used for chlorination treatment, deepening, etc., and the coloring uniformity of the fabric is different.
At the same time, the cloth processing machine is limited to the processing of wool gray cloth, which is used to develop and produce all-wool piece-dyed extra-black worsted fabrics, but it cannot process chemical fibers and other varieties, so it is difficult to develop and produce wool-chemical fiber blended piece-dyed extra-black worsted fabrics
Therefore, the piece dyed extra-black worsted fabric produced by the above method has very unstable dyeing depth, uniformity, color fastness, etc., the qualified rate of finished products is low, the production is difficult, or even impossible to produce, the variety is limited, and the production cost is high.

Embodiment 1

[0104] The piece-dyed extra-black worsted fabric produced in this embodiment is all-wool extra-black gong, and is subjected to three-proof and antistatic functional finishing. The whole wool piece dyed special black tribute cloth of the above specifications is produced through the production processes such as preparation→spinning→weaving→dyeing and finishing.

[0105] 1. Preparation: select all 19.5um (micron) Australian wool fiber tops as raw materials.

[0106] 2. Spinning: spinning warp and weft, warp: 64 s (Public count) / 2, single yarn 710 twists / m, twist direction Z, strands 820 twists / m, twist direction S; weft yarn: 40 s / 1, single yarn 850 twists / m, twist direction S.

[0107] 3. Product specifications: Manufacture of variable twill weave tribute fabric: warp density 380 threads / 10cm, weft density 350 threads / 10cm, cloth width 156cm, fabric weight 220g / square meter.

[0108] 4. Dyeing and finishing:

[0109] (1) Pretreatment: the process steps are as follows:

Embodiment 2

[0152] In this embodiment, weaving and weaving all-wool Lycra machine washable piece dyed extra black serge, the specifications are as follows:

[0153] All-wool Lycra machine washable piece-dyed super black serge fiber raw material blending ratio of 97.5% 18.5um Australian wool fiber and 2.5% Lycra fiber, warp 78 s / 2, single yarn 780 twists / m, twist direction Z, strands 920 twists / m, twist direction S twist, weft yarn 50 s / 1, single yarn 1050 twists / m, twist direction S, 2 / 1 twill weave, warp density 360 threads / 10cm, weft density 350 threads / 10cm, fabric width 152cm, fabric weight 185g / square meter, and Carry out three-proof, machine washable functional finishing.

[0154] This example is similar to Example 1 in the production process of preparation→spinning→weaving→dyeing and finishing. The difference from Example 1 is that the selected 18.5um Australian wool fiber is changed in the preparation process. Raw tops are subjected to chlorination, which comprises the followi...

Embodiment 3

[0194] This example is basically similar to Example 2. It is made of wool-polyester conductive three-proof piece dyed black veritin. The specifications of different fabrics are as follows:

[0195] The blending ratio of fiber raw materials is 70% of 20.5um mercerized wool, 29.2% of 3D (denier) polyester and 0.8% of conductive fiber, warp yarn 56 s / 2, single yarn 620 twist / m, twist direction Z, strand 660 twist / m, twist direction S twist, weft yarn is the same as warp yarn, 1 / 1 plain weave, warp density 240 / 10cm, weft density 220 / 10 cm, cloth width 152 cm. The weight of the fabric is 170 grams per square meter, and it must be finished with three anti-functions.

[0196] The difference between the production process of this example and Example 2 is: the production method of wool-polyester conductive three-proof piece dyed special black veritin, including production processes such as combing, spinning, weaving, dyeing and finishing, and the selection ratio of the preparation pr...

Abstract

The invention discloses a piecedyed jet black fine-spun facing and a preparation method thereof, and relates to the technical field of wool spinning. Raw fiber used comprises natural wool fiber. The preparation method comprises steps of preparation, spinning, weaving, dyeing, finishing and the like. The method is characterized in that the raw fiber used further comprises wool natural fiber, and non-wool natural fiber or / and chemical fiber blended spinning material. The preparation method comprises a step of wool top chlorination treatment in the preparation step, or fabric chlorination treatment in the step of dyeing and finishing, further comprises steps of low-temperature plasma treatment in the steps of preparation, spinning or dyeing and finishing to generate obvious dyed color to enhance effect, so even jet black wool and blended-spun and fine-spun facing without dyeing defect can be obtained. Detection by a computer color photometer shows that blackness of the facing is deep, L value is up to 3.5-9.5, chromatic aberration between pieces is small, and delta E is equal to or less than 0.5. No expensive piece goods treating machine is needed, and the method has the advantages oflow cost, simple process and stable quality.

Description

technical field [0001] The invention relates to the technical field of wool textiles, in particular to a piece-dyed ultra-black worsted fabric and a manufacturing method thereof. Background technique [0002] Worsted woolen fabric has good overall wearing performance, and is welcomed as a high-end clothing fabric in the international and domestic markets. The special black worsted fabric in the above products is a worsted fabric with a black depth far exceeding the black depth of normal dyeing. It is very popular in Europe, America, South Korea, and especially in the Japanese market. Black worsted fabric has great market demand and prospect. For extra-black worsted fabrics, the prior art generally adopts cloth processing machines and corresponding processes to chlorinate wool fabrics, etc., to produce all-wool dyed extra-black worsted fabrics. However, first of all, the cloth processing machine is expensive and the production cost is high; secondly, the cloth processing ma...
