Linen/polyester filament self-adhesive core-spun yarn production equipment and method

Abstract

The invention discloses linen / polyester filament self-adhesive core-spun yarn production equipment and method. The linen / polyester filament self-adhesive core-spun yarn production equipment comprisesa linen staple roving, a dope dyeing polyester filament yarn and a low-melting-point polyester filament yarn; the linen staple roving is transported to a front roller in front through a back roller and a roving stretch apron; the dope dyeing polyester filament yarn is unwound from a bobbin and bypasses a guide wire tension wheel upwards, and passes through a low-melting-point polyester filament yarn bobbin bracket and a bobbin core of a low-melting-point polyester filament yarn bobbin; the low-melting-point polyester filament yarn is unwound from the bobbin and meets with the dope dyeing polyester filament yarn above the bobbin and bypasses a yarn guide, and a low-twist combined filament yarn is formed; and the low-twist combined filament yarn meets with fibers that are stretched by the linen staple roving at the front roller, a linen / polyester filament core-spun yarn is formed under the action of a twisting triangular space, and the linen / polyester filament core-spun yarn passes through a steel collar on a linen spinning frame steel collar and is wound on a ring bobbin. According to the linen / polyester filament self-adhesive core-spun yarn production equipment provided by the invention, the effect of improving the yarn strength and reducing the yarn hairiness falling off can be achieved, the dyeing depth of linen blended yarn fabrics can be improved, the color fastness of thefabrics can be improved, and the good settability and conformality of the fabrics can be improved.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a linen / polyester filament self-adhesive core-spun yarn production equipment and method. Background technique [0002] Core-spun yarn, also known as composite yarn or covered yarn, is a new type of yarn composed of two or more fibers. The original core-spun yarn is short fiber and short-fiber core-spun yarn developed with cotton fiber as the skin and polyester spun yarn as the core. [0003] Core-spun yarn is generally a yarn made of synthetic fiber filaments with good strength and elasticity as the core yarn, and short fibers such as cotton, wool, and viscose fibers are twisted and spun together. The core-spun yarn combines the excellent properties of the filament core yarn and the outer staple fiber. The more common core-spun yarn is polyester-cotton core-spun yarn, which uses polyester filament as the core yarn and is covered with cotton fibers. There is also spandex core-...

Problems solved by technology

[0011] However, the current core-spun yarn production process cannot reasonably control the tension gradient due to the different tensions of the raw materials used to make the core-spun yarn. Serious loss of thread hairiness
