Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

The first embodiment is as follows:

a high-strength antistatic cashmere sweater is knitted by high-strength antistatic cashmere yarns. As shown in fig. 1 and 2, the high-strength antistatic cashmere yarn includes spandex filament 1, high-strength polyester fiber yarn 2, and cashmere fiber yarn 3; the spandex filament 1 and the high-strength polyester fiber yarn 2 form a covering yarn structure, the spandex filament 1 is a core yarn, and the high-strength polyester fiber yarn 2 is a covering yarn; the cashmere fiber yarn 3 is spirally wound outside the high-strength polyester fiber yarn 2 in a double-strand manner; and an antistatic filament yarn 4 is arranged between the high-strength polyester fiber yarn 2 and the cashmere fiber yarn 3, the antistatic filament yarn 4 is spirally wound on the outer surface of the high-strength polyester fiber yarn 2, and the winding direction of the antistatic filament yarn 4 is opposite to that of the cashmere fiber yarn 3.

Preferably, the cashmere fiber yarn 3 is completely wrapped and wound outside the high-strength polyester fiber yarn 2. The hand feeling of the cashmere fiber yarn 3 can be kept to the maximum extent by complete wrapping and winding. Avoid the contact of inside high-strength polyester fiber yarn 2 and human body to influence the wearing experience of cashmere yarn.

Preferably, the cashmere fiber yarn 3 is an anti-pilling high-quality cashmere yarn. The pilling is one of the most common problems of the cashmere sweater, and the look and the experience of the cashmere sweater are influenced very much, so that the anti-pilling high-quality cashmere yarn is adopted in the embodiment, the pilling on the surface of the cashmere sweater can be reduced and avoided, and the texture of the cashmere sweater is improved. Specifically, the preparation steps of the anti-pilling high-quality cashmere yarn are as follows: a, averagely dividing original cashmere fibers with the average length of 15-40mm into three parts, namely cashmere A1, cashmere A2 and cashmere A3; step B, carding the cashmere A1, the cashmere A2 and the cashmere A3 respectively, wherein short fibers with the length within 1mm are removed from the cashmere A1 to obtain cashmere B1; removing short fibers with the length within 10mm from cashmere A2 to obtain cashmere B2; removing short fibers with the length within 25mm from cashmere A3 to obtain cashmere B3; step C, carrying out antibacterial treatment on cashmere B1 to form a porous antibacterial film on the surface of cashmere B1 to obtain cashmere C1; step D, soaking cashmere B2, cashmere B3 and acrylic fibers in a mixed solution of an antistatic agent and an anti-pilling agent to obtain cashmere D2, cashmere D3 and acrylic fibers D4; e, mutually twisting cashmere D2 and cashmere D3 to obtain a yarn E1; mutually twisting cashmere C1 and acrylic fibers D4 to form a yarn E2; step F, softening the yarn E2, and soaking the yarn E2 in a protective solution to form a protective film on the surface of the yarn E2 to obtain a yarn F; step G, coating the yarn E1 on the surface of the yarn F to obtain a yarn G; and h, performing antibacterial treatment on the yarn G to form a porous antibacterial film on the surface of the yarn G to obtain a finished product.

The acrylic fiber is called by artificial wool, has the characteristics of softness, fluffiness, light resistance, bacteria resistance, moth resistance and the like, and can be perfectly blended into high-strength antistatic cashmere yarns. Preferably, the preparation steps of the acrylic conductive filament are as follows: a. shaping and twisting the untwisted acrylic filaments on a shaping machine to form a shaped and twisted acrylic filament yarn bobbin, wherein the boiling water shrinkage of the filaments after shaping and twisting is less than or equal to 1.5%, and the twist is 90-100 t/m: b. after the acrylic filament yarn barrel after shaping and twisting is processed by a bobbin winder, the acrylic filament yarn is placed on a yarn loosening pipe to be made into a yarn loosening barrel, and the weight and the external dimension of the yarn loosening barrel are completely consistent: c. placing the yarn loosening barrel in a closed container, then deoiling in a bidirectional pressure washing mode, and centrifugally dewatering after deoiling to form a dewatered and deoiled yarn loosening barrel; d. c, placing the dehydrated and deoiled loose yarn barrel prepared in the step c into a closed container, and performing impregnation deposition on aniline monomers on the surface of the fiber by a pressurized impregnation method to form an aniline-impregnated loose yarn barrel; wherein, the components of the impregnation liquid applied in the pressure impregnation comprise: aniline,

Hydrochloric acid, a fiber swelling agent, an adsorption catalyst and deionized water; e. placing the pine cone soaked by aniline in a closed container, and realizing oxidative polymerization of aniline monomer adsorbed on the surface of the fiber by a bidirectional pressure soaking method to form a pine cone with a conductive function; wherein, the components of the oxidative polymerization liquid used in the bidirectional pressure impregnation in the step include: ammonium persulfate, hydrochloric acid, toluenesulfonic acid and deionized water; f. and (3) pressing and washing, dehydrating, drying and oiling the yarn loosening barrel with the conductive function, and finally processing the yarn loosening barrel by a winding machine to obtain the finished product acrylic conductive filament.

Example two:

as shown in fig. 3, the present embodiment is different from the first embodiment in that: the polylactic acid filament 5 is spirally wound outside the high-strength polyester fiber yarn 2; the polylactic acid filament yarns 5 and the cashmere fiber yarns 3 are alternately arranged and wound outside the high-strength polyester fiber yarns 2. The polylactic acid filament 5 has the characteristics of crease resistance, rebound, flame retardance, bacteriostasis, soft and smooth hand feeling and the like, can change the hand feeling of the cashmere yarn, enables the cashmere yarn to be smoother, can prevent the cashmere yarn from breeding bacteria, and improves the safety and the sanitation of the cashmere yarn.

Example three:

as shown in fig. 4, in this embodiment, in addition to the first embodiment, a cuprammonium rayon yarn 6 and an acrylic fiber yarn 7 are crossly wound outside the cashmere fiber yarn 3, and the pitches of winding the cuprammonium rayon yarn 6 and the acrylic fiber yarn 7 are both 1-3mm, and in this embodiment, 1.5 mm. The cuprammonium fiber yarn 6 and the acrylic fiber yarn 7 both have good hand feeling, and can improve the structural strength and the wear resistance of the cashmere yarn on the basis of not influencing the hand feeling of the cashmere yarn, and can prolong the service life of the cashmere sweater. Specifically, the copper ammonia fiber yarn 6 and the acrylic fiber yarn 7 have the same fineness and are wound outside the cashmere fiber yarn 3 in a crossed manner.

The foregoing has described in detail preferred embodiments of the present invention.
