Description

[Technical field]

[0001] The present invention relates to the technical field of wool yarns and their products, and more particularly to machine washable wool yarns and fabrics having a sheath-core structure. [Background technology]

[0002] As a high-quality fabric, wool yarn has the advantages of short fibers, softness, thinness, lightness, and comfortable wear, but it also has some obvious disadvantages. First, wool yarn has average strength, which means that its durability is relatively low, it cannot withstand strong friction and pressure well, and it is easy to wear during use. Second, wool yarn is prone to shrinkage. Although mercerized wool yarn has good shrinkage resistance, it is necessary to pay attention to the appropriate washing method and temperature when machine washing, and it is not suitable for all woven fabrics. Therefore, there is a demand for the development of wool yarn with high strength, high shrinkage resistance, and machine washable.

[0003] Chinese Utility Model No. 220318067 discloses a shrink-proof wool yarn, which includes a shrink-proof wool core-spun yarn and a wool worsted yarn, and the wool worsted yarn is twisted with the shrink-proof wool core-spun yarn, and the shrink-proof wool core-spun yarn is composed of a core yarn made of flax fiber yarn and a covering fiber layer made of mercerized wool. The shrink-proof wool yarn according to the utility model can effectively exert a shrink-proof effect because the surface scale of the mercerized wool employed is removed, and the dimensional stability of the woven fabric can be improved by adopting the flax fiber yarn. In addition, the twisted wool worsted yarn can suppress the phenomenon of fluffing and pilling of the wool yarn. Although the wool yarn based on the utility model has a reduced shrinkage rate, it still suffers from serious shrinkage after repeated machine washing, and there is a need to improve the machine washing performance.

[0004] [Patent Document 1] China Utility Model No. 220318067 Summary of the Invention [Problem to be solved by the invention]

[0005] In order to solve the problems existing in the prior art, the present invention provides machine washable wool yarn and fabric with a sheath-core structure, thereby solving the problems of wool yarn having average strength, low shrink resistance, and poor machine wash performance. [Means for solving the problem]

[0006] The technical solution of the present invention to solve the above problems is a machine washable wool yarn having a core-sheath structure, characterized in that the wool yarn includes a core fiber having a sheath fiber fitted around its periphery and formed by winding several long fiber yarns, and the sheath fiber includes a short fiber yarn having a reinforcing layer disposed around its periphery.

[0007] Furthermore, the above-mentioned staple fiber yarn contains wool as a main component, and contains staple fibers such as cotton, polylactic acid, hemp, cotton, modified acrylic, lyocell, rayon, and modal as other components.

[0008] Furthermore, the proportion of wool in the above staple fiber yarn is 2 to 90%.

[0009] Furthermore, the reinforcing layer is a polyfunctional aliphatic oxygen compound, which is any one of ethylene glycol diglycidyl ether, diethylene glycol diglycidyl ether, and triethylene glycol diglycidyl ether.

[0010] Further, the filament yarns may include one or more of filaments such as polycarbonate, polymethylmethacrylate, polyester, polyethylene, polypropylene, polyurethane, polyamide (nylon), cellulose acetate, rayon filaments, lyocell filaments, and the like.

[0011] Furthermore, the above-mentioned long fiber yarn is two pieces.

[0012] Furthermore, the sheath fibers account for 2 to 98% by weight of the wool yarn.

[0013] The fabric is made from the machine washable wool yarn. Effect of the Invention

[0014] The present invention has the following beneficial effects over the prior art: The long fiber yarns are wound around each other, improving the elasticity and strength of the core fiber; The short fiber yarns are reinforced with a multifunctional aliphatic oxygen compound to form a reinforcing layer that fixes the wool and the core fiber, improving the strength, strength and elongation of the wool and significantly improving performance; The overall performance, elasticity, pilling and pilling performance, and recovery of the wool yarn are significantly improved, making the wool yarn bounce back better in machine washing and improving shrink resistance.
