Embodiment 1

[0015] Spin 15% of LPET (modified polyester with low melting point) and 85% of PET (conventional polyester) into sheath-core composite fiber, wherein the core layer is PET and the skin layer is LPET. After conventional processes such as drawing and crimping, the chenille core yarn with low-temperature fusion bonding characteristics is formed.

[0016] In the process of spinning chenille yarn, the core yarn is twisted, the outer yarn guide rotates along the inner yarn guide, and the velvet yarn is continuously wound on the inner yarn guide, and the velvet yarn formed The circle is cut regularly by a knife driven by a cam, and the velvet yarn circle is cut into two and a half circles, and the short section of velvet yarn fiber is sandwiched in the twist of the core yarn to form a chenille yarn. Then through the twisting machine, the chenille yarn is twisted on the scaffold by a certain weight or a certain length, and then the twisted chenille yarn is sent into an oven for baking...

Embodiment 2

[0018] Spin 30% LPET (modified polyester with low melting point) and 70% PET (conventional polyester) into sheath-core composite fiber, wherein the core layer is PET and the skin layer is LPET. After conventional processes such as drawing and crimping, the chenille core yarn with low-temperature fusion bonding characteristics is formed.

[0019] In the process of spinning chenille yarn, the core yarn is twisted, the outer yarn guide rotates along the inner yarn guide, and the velvet yarn is continuously wound on the inner yarn guide, and the velvet yarn formed The circle is cut regularly by a knife driven by a cam, and the velvet yarn circle is cut into two and a half circles, and the short section of velvet yarn fiber is sandwiched in the twist of the core yarn to form a chenille yarn.

Abstract

This invention provides paper line-core composite fiber materials of Chenille Yarn and a technology for spinning not-shed Chenille yarn, in which, according to this invented plan, the skin-core composite fibers used as the core-yarn of the Chenille yarn are spun with 15-30% low melting point modified polyester and 70-85% ordinary polyester, and the core-layer is the ordinary polyester and skin layer is the low melting point modified polyester, and the core-yarn is ring twisted with soft yarn to become Chenille yarn, which is baked under a certain temperature, and part of skin of low melting point is melted to be coated on the joint point of the core and the soft yarn to increase the joint force of them.

Description

technical field [0001] The invention relates to the field of textile products and technology, in particular to provide a sheath-core composite fiber material suitable for use as chenille core yarn and a process for spinning non-shedding chenille yarn with it, which belongs to fancy yarn Improvement of thread quality and spinning process. technical background [0002] In the existing products, the raw materials used as chenille core yarn mainly include polyester, acrylic, viscose, cotton yarn, etc., and a low-temperature thermal fusion yarn is also added to the core yarn together as the core yarn to spin chenille yarn. , to play the role of strengthening and fixing the velvet yarn, but the effect is not obvious, and it has not been popularized and applied. The shedding problem of the velvet yarn of the existing chenille thread products has become a major technical problem restricting the development of the industry. [0003] On the other hand, from the spinning method of ch...
