Problems solved by technology

[0006] The purpose of the present invention is to provide a dual modulus triple that can not only meet the requirements of small deformation, but also meet the requirements of large deformation, and improve the tightness, shape retention and comfort of clothing. Component composite yarn to overcome the problem that the existing composite yarn does not have a double modulus of elasticity, so that the fabrics made are not very versatile for clothing making

[0020] Example Manufacture of Composite Yarn

[0021] Combined with ZL02104397.3, on the FA506 ring spinning machine, the staple fiber strands as the outsourcing fibers are fed to the cradle drafting mechanism through the bell mouth of the machine for drafting, and the network yarns (PET DTY77dtex / 36f+PU 44dtex / 1f) is drawn out from the filament unwinding device, filament tension control device and filament positioning guide device, and then fed into the nip of the front roller from the rear of the front roller. twisting zone. Before entering the composite twisting zone, the tension of the filament is controlled by a specific tension device, so that the tension value of the filament is kept stable and within a reasonable range during spinning; at the same time, the filament is controlled by a positioning guide device to be aligned with the center of the staple fiber. Entering the twisting triangle area ensures the coaxial composite twisting of staple fiber strands and filamen...

Abstract

The invention provides three-component composite yarn which is formed by combined machining of 5%-30% of inner-layer core yarn and 70%-95% of outer-layer chopped fiber based on weight ratio via a ring spinning frame, wherein, the inner-layer core yarn of the composite yarn is formed by air texturing and machining of polyester filament yarn or polyamide filament yarn and polyurethane. The composite yarn of the invention has double modulus of elasticity and can improve generality of materials on garment after being made into fabrics, thus meeting the requirement for the modulus of elasticity in case of small deformation as well as the requirements for the modulus of elasticity and shape recovery ratio in case of large deformation, and improving close-fitting property, shape retention property and comfort while wearing clothes.

Description

technical field [0001] The invention relates to a fabric fiber, in particular to a three-component composite yarn and a yarn forming method. Background technique [0002] Composite yarns made of a variety of fibers have been used in the current textile industry, and there are many types. According to the various fiber types that make up the composite yarn, these composite yarns can be roughly divided into: composite yarns composed of short fibers and short fibers, composite yarns composed of chemical fiber filaments and short fibers, and composite yarns composed of chemical fiber filaments and chemical fiber filaments. Three categories of yarn. At present, more composite yarns are generally made of chemical fiber filaments as the core yarn, and a composite yarn with a unique structure formed by outsourcing various short fibers. The commonly used chemical fiber filaments for its core yarn include polyester filaments, nylon filaments, spandex filaments, etc. Outsourced shor...
