Problems solved by technology

However, the ultra-black worsted wool fabrics currently sold in the market are always unsatisfactory, because they are all dyed with cloth, that is, the wool strips are combed, spun and woven to make wool cloth fabrics, and the fabrics are then dyed by cloth. Picklaoy (wool mercerized anti-shrink treatment), dyeing and finishing process to produce ultra-black wool worsted fabric; because the cloth cannot be completely treated in the same way when the wool mercerized anti-shrink treatment, so that the dyed fabric It is easy to have cylinder difference, piece difference and color difference on a piece of cloth. After the computer color measurement system test, the value fluctuates greatly, which makes the color of the garments made have differences; and the color difference between batches of fabrics is also large; As a result, the first-class rate of ultra-black wool worsted fabrics produced by piece dyeing is relatively low, generally 60-70%.

example 1

[0022] The following steps are taken to produce ultra-black worsted wool fabrics with 80S Australian wool strips:

[0023] (1) The wool sliver is subjected to wool mercerizing and anti-shrinking treatment, the process is: wool chlorination and dephosphorization→dechlorination→neutralization→cleaning→wool acidification→softening→drying;

[0024] (2), use the leveling agent Pingpingjia to carry out the pretreatment of wool strips, the dosage is 0.5% (o.w.f), and the treatment temperature is 80°C; the wool strips are dyed, and the process is to add the dye Da Aiman ​​black PLC at 40°C, The dosage is 10% (o.w.f), the pH value is 3.5-4.5, heat up to 100°C, keep warm for 25 minutes, add acetic acid, keep warm for 20 minutes, then cool down to 65°C, add oxidant sodium dichromate, and then heat up to 100°C to keep warm Rinse after 50 minutes; wool strips are processed after dyeing, the detergent is detergent 209, and the leveling agent is Pingpingjia;

[0025] (3) The wool sliver is ...

example 2

[0027] Use 80S Australian wool strips to produce ultra-black wool worsted fabrics, the dye is medium black PV, and its dosage is 10% (o.w.f); the darkening agent is darkening agent 2002P, and other production processes are the same as Example 1.

[0028] Example 1 and Example 2 are tested and their numerical values ​​are as follows:

Abstract

The present invention relates to a kind of super black wool spun material and features that the warp and weft of the material are made of wool ribbons after their dyeing and through the re-combing process, and the spun yarns. The invention also relates to a preparing method for the material. By applying to this invention, the material has an even color and luster, and the same batch of cloth cover materials has no difference one from the other; the same is true with different batches of cloth cover materials. The first-rate product of this material accounts for over 98%.

Description

1. Technical field [0001] The invention relates to a worsted wool fabric, in particular to an ultra-black worsted wool fabric and a preparation method thereof. 2. Background technology [0002] As a natural fiber, wool has always been a relatively high-end textile raw material and is deeply loved by consumers because of its soft feel, firm texture, good curl elasticity and warmth retention, and natural and soft luster. Super black wool worsted fabric is currently the best-selling color in the market, and it is often used as a formal dress fabric. Especially in the Japanese market, almost every adult has two sets, and its demand is very high. However, the ultra-black worsted wool fabrics currently sold in the market are always unsatisfactory, because they are all dyed with cloth, that is, the wool strips are combed, spun and woven to make wool cloth fabrics, and the fabrics are then dyed by cloth. Picklaoy (wool mercerized anti-shrink treatment), dyeing and finishing process...
