Abstract

The utility model provides a core-spun yarn in which the core yarn is a two-for-one-twisted filament yarn. The two-for-one-twisted filament yarn obtained by two or more filaments through two-for-one twisting processing is used as the core yarn, and the outsourcing short fiber yarn is spun. Formed, wherein the twist direction of the filament two-for-one twisted yarn is opposite to that of the outer staple fiber yarn. This patent uses filament double-twisted yarn as the core yarn, which can effectively improve the overall strength of the yarn. At the same time, the twist direction of the filament double-twisted core yarn and the outer short fiber yarn is opposite, which can effectively reduce the overall twist of the yarn, making the yarn Soft to the touch.

Description

A kind of heart yarn is the cladded yarn of long filament times twist yarn

Technical field

The utility model relates to spinning new technical field, and a kind of heart yarn is the cladded yarn of long filament times twist yarn specifically.

Background technology

RING SPINNING technology is current domestic and international application the most a kind of spinning technique, this technology adds the generation of filoplume due to the existence of twist triangle zone, simultaneously in twist triangle zone because of the length of limit fiber and center fiber, percentage elongation and stress difference, the radially inside and outside transfer of fiber is made in twisting resultant yarn process, winding repeatedly, the yarn strength being is higher.But compared with various novel spinning mode, RING SPINNING spinning speed is lower, and therefore output is lower.

Cladded yarn is also known as composite yarn or wrap yarn, and it is by a kind of new type yarn of two or more fiber combinations.Generally with powerful and elastic force, synthetic fiber filament is for core silk all preferably for cladded yarn, and the yarn spinned twisted together by the staple fibres such as outsourcing cotton, hair, viscose.Cladded yarn has the premium properties of long filament heart yarn and outsourcing staple fibre concurrently.At present, general cladded yarn all adopts one filament as the feeding of core silk, and the entirety brute force of yarn is restricted.

For this, the utility model provides the cladded yarn that a kind of heart yarn is long filament times twist yarn, it adopts double joint or plurality of threads to process through double twisting the long filament times twist yarn obtained is heart yarn, and outsourcing short fibre yarn spinning forms, wherein long filament times twist yarn sth. made by twisting to the sth. made by twisting of outsourcing short fibre yarn to contrary.This patent adopts long filament times twist yarn as heart yarn, and the entirety that effectively can improve yarn is powerful, and the sth. made by twisting of long filament double twisting heart yarn and outsourcing short fibre yarn is on the contrary simultaneously, effectively can reduce the overall twist of yarn, make yarn soft.

Summary of the invention

The purpose of this utility model provides the cladded yarn that a kind of heart yarn with features such as brute force are high, feel is soft is long filament times twist yarn.

For achieving the above object, the technical solution adopted in the utility model is: a kind of heart yarn is the cladded yarn of long filament times twist yarn, comprise heart yarn and outsourcing yarn, described heart yarn is adopt double joint or plurality of threads to process the long filament times twist yarn obtained through double twisting, described long filament is spandex, chinlon filament or polyester filament, described outsourcing yarn is short fibre yarn, and described short fibre yarn is cotton yarn, terylene short fiber, polyamide fibre short fiber or wool fibre, Down Fiber, the sth. made by twisting of described heart yarn to the sth. made by twisting of outsourcing yarn to contrary.

The utility model heart yarn is the production method of the cladded yarn of long filament times twist yarn: first, continuous yarn two-for-one twister is produced long filament times twist yarn, secondly, ring spinning frame installs core-spun yarn device additional, a spinned long filament times twist yarn is fed as heart yarn, outsourcing staple fibre rove is fed by rear roller, and the long filament times twist yarn of feeding converges in front roller exit with the spun staple yam obtained after roller draft, jointly obtains required cladded yarn through spindle mechanical twisting.

The beneficial effects of the utility model are: adopt long filament times twist yarn as heart yarn, and the entirety that effectively can improve yarn is powerful, and the sth. made by twisting of long filament double twisting heart yarn and outsourcing short fibre yarn is on the contrary simultaneously, effectively can reduce the overall twist of yarn, make yarn soft.

Detailed description of the invention

As depicted in figs. 1 and 2, a kind of heart yarn is the cladded yarn of long filament times twist yarn, comprise heart yarn 2 and outsourcing yarn 1, heart yarn 2 is adopt double joint or plurality of threads to process the long filament times twist yarn obtained through double twisting, long filament is spandex, chinlon filament or polyester filament, outsourcing yarn 1 is short fibre yarn, and described short fibre yarn is cotton yarn, terylene short fiber, polyamide fibre short fiber or wool fibre, Down Fiber, the sth. made by twisting of heart yarn 2 to the sth. made by twisting of outsourcing yarn 1 to contrary.

Claims

1. a kind of core yarn is the core-spun yarn of filament two-for-one twisted yarn, comprises core yarn and outer covering yarn, is characterized in that: described core yarn is the two-for-one filament that adopts double or multiple long filaments to obtain through two-for-one twisting process Twisted yarn, the filament is spandex, nylon filament or polyester filament, the outsourcing yarn is staple fiber yarn, and the staple fiber yarn is cotton yarn, polyester staple fiber, nylon staple fiber, or wool fiber, velvet fiber, The twist direction of the core yarn is opposite to that of the outer covering yarn.
