Description

A kind of covering yarn structure

Technical field

The utility model belongs to textile industry, and in particular to a kind of covering yarn structure.

Background technology

Covering yarn is that, using long filament as core, chopped fiber is the yarn of the clad structure of skin, belongs to composite yarn.Common yarn core long filament has Dacron thread, Polyamide Yarns and spandex thread etc., outer wrapping fiber is often with cotton, polyester-cotton blend, acrylic fibers, wool etc..Covering yarn be mainly used as sewing thread, Shirt fabric, burnt-out fabric and stockinette etc..Sewing thread is generally that high tenacity polyester filament does yarn core with covering yarn, outsourcing cotton fiber, Core filaments provide strength, elasticity, and outer layer fiber bears high temperature and the heat setting temperature produced with pinprick friction；Shirt fabric is conventional to be washed Cotton covering yarn, cotton content is higher outside, makes fabric both well-pressed, have again moisture absorption, it is ventilative, without electrostatic, it is comfortable and easy to wear the features such as；Wash After cotton covering yarn woven into fabric, using the different solubility property of fiber, handled with chemical reagent, make part cotton fiber on fabric molten Solution, retains polyester filament, as " etching " fabric with part translucent decorative pattern；It is yarn core with spandex, with cotton, polyester-cotton blend, washs Synthetic fibre or acrylic fibers etc. are the covering yarn that outer wrapping fiber is made, and stockinette processed can be knitted, as swimming suit, anorak, jean etc..

A difficulty for being difficult to capture, i.e. covering yarn are still had in current chopped fiber filament core-spun yarn properties of product " Rose " phenomenon.Often there is substantial amounts of spot fault in the dyed rear cloth cover of covering yarn fabric, and these spots are due to spin bag The covered effect of heart yarn is too poor to be caused, especially core filaments ratio is higher and dyeabilities of core filaments and Cortical fiber dyeability When having larger difference, core filaments degree of exposure is serious, the limitation that traditional ring spinning is produced in itself, it is impossible to fundamentally solve this One problem.

Utility model content

The purpose of this utility model is exactly to provide a kind of covered effect strong covering yarn structure to solve the above problems.

The purpose of this utility model is achieved through the following technical solutions：

A kind of covering yarn structure, by the long filament yarn core of internal layer, the first short fiber layers being wrapped in outside long filament yarn core and bag It is rolled in the second short fiber layers composition outside the first short fiber layers, the first described short fiber layers and the weight ratio of the second short fiber layers For 2-4：6-8, described the first short fiber layers and the second short fiber layers are that Z is twisted with the fingers, the first described short fiber layers and second short The English twist multiplier of fibrous layer is 410-430.

Preferably, the English twist multiplier of the first described short fiber layers and the second short fiber layers is 420.

Preferably, described long filament yarn core is the yarn core long filament using dacron thread, Polyamide Yarns or spandex thread, and fibre fineness is 70-100D, it is further preferred that the fibre fineness of described long filament yarn core is 75D.

Preferably, the first described short fiber layers are the chopped fiber using cotton, viscose glue, Modal or polyester-cotton blend, fiber finer Spend for 1-2D, length is 35-60mm, it is further preferred that the fibre fineness of the first described short fiber layers is 1.2D, length is 38mm。

Preferably, the second described short fiber layers are the chopped fiber using cotton, viscose glue, Modal or polyester-cotton blend, fiber finer Spend for 1-2D, length is 35-60mm, it is further preferred that the fibre fineness of the first described short fiber layers is 1.2D, length is 38mm。

The specific manufacture craft of the utility model covering yarn structure is, after process of roving, and two groups of rove are fed carefully together Yarn machine, meanwhile, the corresponding front roller feeding long filament yarn core of a chopped fiber rove, then converged jointly with another chopped fiber rove thereto Close twisting and obtain covering yarn.The weight ratio of first short fiber layers and the second short fiber layers is 2-4：6-8, because two chopped fibers are thick The quantitative difference of yarn, when common twisting, suffered drafting force is different from centrifugal force, and weight is first wrapped than the first low chopped fiber rove Long filament is covered, weight is coated on outside the first short fiber layers again than the second high chopped fiber rove, so that it is stronger to form covered effect Yarn texture.

The beneficial effects of the utility model are：By feeding two quantitative different rove, and it is common with light basis weight rove With the long filament introduced, two layers of outsourcing chopped fiber is formed, a long filament yarn core is wrapped up, reaching is not influenceing the situation of fineness of yarn Under, the strength of covered effect and yarn is improved, long filament yarn core is wrapped up using two groups of chopped fibers, increases covered effect, reduction is knitted Fault is made, the exposed situation of yarn core can be substantially reduced, makes follow-up woven fabric more smooth, the problem of solving aberration.
