Description

Wool blended yarn and preparation method and application thereof
Technical Field
The invention belongs to the field of textile materials. In particular, the invention relates to wool blended yarns and a preparation method and application thereof.
Background
The blended yarn refers to a yarn blended by two or more different fibers according to a certain ratio, such as a polyester-cotton blended yarn, a polyester-viscose blended yarn, and the like. The performance can be complemented by adopting the blending of various fibers, the wearability of the fabric is further provided, the functional characteristics of the product are enhanced, and the added value of the product is improved.
The wool fiber is animal protein fiber, has good elasticity, rich hand feeling, good heat preservation performance, strong moisture absorption capacity and soft luster, and can be made into products with different styles. However, wool fibers have lower strength, and the wool market is constantly searching for more durable materials to help improve the strength, abrasion resistance, etc. of wool and high performance materials to provide cooling, fast drying, reduced pilling, and other related properties.
CN106048804A discloses a blended yarn of spun silk, wool, A tencel, normal temperature cationic polyester and combed cotton, wherein the spun silk accounts for 5-40 parts by weight, the wool accounts for 5-40 parts by weight, the A tencel accounts for 10-80 parts by weight, the normal temperature cationic polyester accounts for 10-70 parts by weight, and the combed cotton accounts for 10-70 parts by weight. The blended yarn has the characteristics of fineness, softness and smoothness of spun silk products, has the function of warming and comfort of wool, and also has the advantages of smoothness and comfort of tencel fibers, color, draping, stiffness and smoothness of normal-temperature cationic terylene and moisture absorption and sweat releasing of combed cotton.
CN104711729A discloses an Yilun and mercerized wool fiber blended yarn and a spinning process thereof, wherein in the blended yarn, the Yilun fiber accounts for 50% -90% of the total mass of the blended yarn, and the mercerized wool fiber accounts for 10% -50% of the total mass of the blended yarn. The blended yarn has the characteristics of the nylon and super cotton-like fiber and the characteristics of the mercerized wool fiber, and the spun yarn is uniform in evenness, high in strength and low in cost.

Compared with pure raw material yarns, the blended yarns have better balance in the aspects of yarn strength, air permeability and heat retention.
The existing wool blended yarn also has the defects of poor skin feel due to too low wool content, low strength due to low content of reinforced fibers, low wear resistance, easy pilling and the like.
At present, no wool blended yarn with 60 wt% of wool content, high strength and good wear resistance is reported. Accordingly, there remains a need in the art for such wool blended yarns.

i) cutting 1600D/960f ultra-high molecular weight polyethylene filament into short fibers, wherein the length of the short fibers is 52mm, and the number of crimps is 8/25 mm;
ii) spraying an emulsion comprising 1.5% by weight of an antistatic agent and 1.5% by weight of a soft smoothing finish ontoThe emulsion is fully permeated into the fiber on the ultra-high molecular weight polyethylene short fiber, so that the water content of the fiber before carding is 12 weight percent and the volume specific resistance value of the fiber is 109Ω · cm or less, wherein the weight percentages of antistatic agent and soft and smooth finish are based on the weight of the emulsion, the fiber moisture content is based on the weight of the fiber;
and iii) combing the pretreated ultra-high molecular weight polyethylene fibers (the on-machine moisture regain is 10%) into raw slivers through combing (a B272 type combing machine) → a first channel comb (a B302 type combing machine) → a second channel comb (a B306 type combing machine) by adopting a semi-combing process, wherein the combing steps are carried out at the temperature of 28 ℃ and the relative humidity of 65%, the water content of the fibers is 6 wt%, and the speed ratio between a cylinder and a working roller is controlled so as to enable the speed ratio to be 10-20% higher than that used for processing the conventional slivers.
The carding process and the needle carding process are as shown in example 1 below.
The weight unevenness rate of the obtained raw slivers is controlled to be less than or equal to 1 percent, the Cv value of the slivers is less than or equal to 5 percent, and the wool grains are less than or equal to 1.5/g. The raw short velvet, the hair grain, the single fiber state and the wool top cohesive force are all better.
II) spinning: the method comprises the following steps of processing polyethylene fiber vitamin strips and wool raw strips into the plied wool blended yarns through a strip mixing process, a combing process, a needle combing process, a roving process, a spinning process and a yarn doubling process.
Wherein the technological parameters of each procedure are as follows:
the procedures of sliver mixing, combing, gilling, roving and spinning are the same as those in the embodiment 1;
and a yarn doubling procedure: and (3) reversely twisting the 2 strands of spun yarns, doubling, wherein the metric twist coefficient is 90, and the winding speed is 800 m/min.
The mechanical properties of the resulting wool blended yarns (No. 4) were tested and compared with 100% wool (No. 5), 50/50 wool/anti-pilling acrylic (No. 6), 50/50 wool/polyester blended yarns (No. 7) of the same count, and the results are summarized in table 3.

Figure BDA0002431087010000131
As can be seen from the results in table 3, the single yarn breaking strength of the wool blended yarn of the present invention is much higher than that of the 100% wool yarn, 50/50 wool/anti-pilling acrylic blended yarn, 50/50 wool/polyester blended yarn of the same count.
Respectively weaving the yarns 4-7 on a 18GG circular knitting machine to form single-sided knitted fabrics (corresponding to the yarns 4-7), wherein the gram weight of the fabrics is 150g/m2。
The obtained single-sided knitted fabric was evaluated for burst strength, abrasion resistance and pilling property, and the results are summarized in table 4.
Table 4: comparison of single-sided knitted fabric performance test data
Figure BDA0002431087010000132
