Embodiment Construction

[0013] The present invention relates to a kind of preparation method of acrylic fiber yarn, described method comprises following process:

[0014] Step 1, using 100% expanded acrylic fiber raw material to carry out single yarn spinning on ordinary spinning equipment, and the yarn produced is Z-twist single yarn with 12 to 16 public counts.

[0015] Step 2. Invert the finished single yarn into a skein with a frame length of 2±0.2 meters, then place it in a steam-type expansion box, inject steam to raise the temperature to 105°C, and keep it for 10 minutes to completely expand the expanded acrylic fiber. The yarn is dyed.

[0016] Step 3, the dyed yarn is dehydrated and dried, and the moisture regain is controlled at 4%±0.2%.

[0017] Step 4: Pour the dyed and dried skein yarn into a bobbin yarn with a capacity of no more than one kilogram, and then perform three-ply yarn paralleling and twisting, and the paralleling is performed according to the design requirements for one col...

Abstract

The invention relates to a manufacturing method of an acrylic yarn, which comprises the following processing steps: 1, carrying out single-yarn spinning on a 100% bulky acrylic material on spinning equipment to obtain a Z-twisted single yarn; 2, reversing the obtained single yarn into a skein of which the frame length is 2+/-0.2 m, placing the skein in a steam type bulking box, and dyeing the skein; 3, dewatering and drying the dyed yarn; 4, reversing the dyed and dried skein into a cone yarn of which the capacity is no more than one kilogram, and tripling and twisting the yarn; 5, carrying out steam shaping on the twisted yarn; and 6, finally napping the yarn which is subjected to tripling, twisting and steam shaping, and controlling acrylic fibers to extend 0.5-0.8 cm from the yarn main body. By improving the yarn-manufacturing process flow to realize deep control on the twist, the bulkiness and the strength of the yarn, the invention improves the various indices of the yarn, changes the yarn from the traditional low-end product to a higher-end product and enhances the substitutability of pure wool with the acrylic yarn.

Description

(1) Technical field [0001] The invention relates to a method for making acrylic yarn. It belongs to the technical field of chemical fiber production. (2) Background technology [0002] The appearance of acrylic fiber is white, curly, fluffy, and soft to the touch. It is very similar to wool. It is mostly used for blending with wool or as a substitute for wool, so it is also called "synthetic wool". At present, the physical index similarity between acrylic yarn and pure wool cannot meet the market requirements. The indicators and their controllability in the spinning process are low, and the style is limited in the use process, which cannot meet the higher comfort proposed by the market for acrylic yarn. sex, skin-friendly demand. Acrylic yarn is insufficient for wool yarn. (3) Contents of the invention [0003] The object of the present invention is to overcome above-mentioned deficiency, provide a kind of making method of the acrylic fiber yarn that makes yarn have mor...
