Problems solved by technology

However, because the fine denier modal fiber is very fine, only 0.9 denier, the strength of the fiber itself is very small, and it is easy to damage the fiber by traditional dyeing and finishing methods. Because the fineness is very fine during dyeing, it is not suitable for ordinary dyes. The quantity is not high, and the dyeing fastness is not very good. Therefore, the yarn color structure produced by conventional methods is single, which cannot meet the needs of individualized consumption.

Embodiment 1

[0055] Select 160 kilograms of fine denier modal loose fibers, put them into a solution with a bath ratio of 1:8 at room temperature, and contain 1% chelating dispersant, 1% biological enzyme scouring agent, heat up to 55 ° C for 30 minutes, let go Foot water, clean with water overflow.

[0056] Using reactive dyes, according to different color requirements and dye ratios, pour the dye and 1 / 5 Yuan Ming powder into the dyeing vat chemical material for 20 minutes, and add 1% fiber protective agent and 2 / 5 Yuan Ming after 10 minutes of normal temperature operation Add the remaining 2 / 5 yuan Mingfen after continuing to operate for 10 minutes, then heat up to the temperature required for dyeing at 1°C / min, select the appropriate alkali addition rate curve according to the characteristics of different dyes, add baking soda and soda ash, a small Add soda first and run for 5 minutes, such as image 3 As shown, the rate of adding alkali should be slow first and then fast, and the alk...

Embodiment 2～3

[0058] The specific steps of spinning are as follows:

[0059] 1. After pre-opening fine denier modal fibers and other chemical fibers or cotton fibers, carry out dyeing treatment, including scouring or bleaching, dyeing, post-treatment and other steps.

[0060] 2. According to the color requirements of the product, match the proportion of fibers of different colors, and weigh various fibers according to the proportion.

[0061] 3. Lay and mix the weighed fibers of different types and colors according to regulations, and lay 1 to 3 layers for each color. If the batch is large, divide it into several small batches for mixing.

[0062] 4. After the raw materials are mixed, they are further mixed in the cleaning process and quantitatively rolled. The dry weight of the lap is 300-550 g / m; the length of the lap is 33-45 meters.

[0063] 5. Card the lap into strips on the carding machine (FA201B). Raw sliver weight is 12-22g / 5m; stripping speed is 45-65m / min.

[0064] 6. Perform...

Abstract

The fine-dentier modal fiber mixed-color spinning yarn comprises two or more fibers with different color special with 40-100% fine-dentier modal fiber that has bright and variable color, soft hand feeling, and well warmth retention property. Compared with prior art, this invention needs no special device, solves the color-float and other problems and special the reduction of high tenacity.

Description

technical field [0001] The invention relates to a melange spinning yarn purely spun with fine denier modal fiber or blended with other fibers and a production method thereof, which belongs to the technical field of spinning engineering in textile industry production. Background technique [0002] Both fine denier modal fiber and ordinary modal fiber are cellulose regenerated fibers with high wet modulus produced by Austrian Lenzing Company. The fiber fineness is 0.9D and the length is 38mm. The raw materials of this product are all natural materials, which are harmless to the human body, can be decomposed naturally, and are harmless to the environment. They are green ecological fibers. Fine denier modal fiber is thinner and softer than ordinary modal fiber, so it has better uniformity, high gloss, softer and smoother properties, good hand feeling and drapability; its silk texture is stronger and more comfortable to wear. Fine denier modal fiber yarn can be woven into high-g...
