Abstract

The invention discloses a preparation method of wool fiber core spun yarn. Filaments are mainly taken as core yarn, wool fiber coating is performed on the surface of the core yarn twice, the twisting direction of wool fibers during the first coating is opposite to the twisting direction of the wool fibers during the second coating, the content of filament core yarn in the wool fiber core spun yarn produced through the method is 20%-35%, and the content of wool fibers is 65%-80%. According to the preparation method of the wool fiber core spun yarn, the filament is coated by the wool fibers twice and twisting directions of coating are opposite, so that sliding of the wool fibers on the surface of the filament core yarn is reduced or avoided, exposed filament core yarn on the surface of fabric is reduced, and the coating effect is good.

Description

A kind of wool fibre cladded yarn preparation method
Technical field
The invention belongs to textile technology field, be specifically related to a kind of wool fibre cladded yarn preparation method.
Background technology
Generally all synthetic fiber filament is as the core silk preferably take powerful and elastic force for cladded yarn, and the staple fibres such as outsourcing cotton, hair, viscose are twisted and the yarn that is spun into together.More common cladded yarn has the polyester-cotton blend cladded yarn, take polyester filament as heart yarn, and the outsourcing cotton fiber; Also have spandex core-spun yarn, take spandex filament as heart yarn, the yarn that other fibers of outsourcing are made.To be staple fibres only coat once in long filament heart yarn outside the shortcoming of these cladded yarns, and the yarn middle short fiber at silk slippage can occur, and causes long filament to come out in some fragment of yarn, produces fault at fabric face, and covered effect is poor.
Summary of the invention
The purpose of this invention is to provide a kind of wool fibre cladded yarn preparation method, solved existing cladded yarn staple fibre in the poor problem of long filament heart yarn outside covered effect.
The technical solution adopted in the present invention is: a kind of wool fibre cladded yarn preparation method, and, to carry out twice wool fibre on the heart yarn surface and coat as heart yarn with long filament, the sth. made by twisting of wool fibre is to the sth. made by twisting of wool fibre when the 2nd time coats to opposite when coating for its 1st time.
Concrete steps are as follows:
Step 1: on three roller drafting mechanisms of the two-region of ring frame, wool fibre rove yarn is fed by horn mouth, and through the drawing-off of reel cage drafter; The front roller nip feeding of polyester filament from gripping converges with drafted wool fibre rove yarn;
Step 2: the twisting area of being carried feeding wool fibre rove yarn through polyester filament by front roller, polyester filament transmits by the accurate feed carrier of making, and the center of aligning wool fibre rove yarn, after converging with wool fibre rove yarn, jointly enter the twist triangle zone twisting of RING SPINNING;
Step 3: by the tension force of filament yarn tension control device control long filament, the fibre bundle in the wool fibre rove yarn after long filament and the drawing-off is at the coaxial composite twist of yarn twist triangle zone, long filament carried out the 1st wool fibre coat and twist;
Step 4: the cladded yarn to step 3 forms, carry out the 2nd wool fibre according to step 1~3 and coat twisting, namely obtain the wool fibre cladded yarn.
Characteristics of the present invention also are,
Wherein, the tension value of long filament is controlled at 20cN~40cN in the step 3.
Wherein, the 1st wool fibre coating and the 2nd wool fibre coat the twist factor of twisting and are 220~280.
Wherein, the content of long filament heart yarn is 20%~35% in the wool fibre cladded yarn of making in the step 4, and the wool fibre content of coating is 65%~80%.
The invention has the beneficial effects as follows, wool fibre cladded yarn preparation method of the present invention, mainly with long filament as heart yarn, carrying out twice wool fibre on the heart yarn surface coats, and the sth. made by twisting of twice coating is on the contrary, so that the slippage of wool fibre on long filament heart yarn surface reduces or disappears, reduce the long filament heart yarn in the exposed phenomenon of fabric face, covered effect is better.
The specific embodiment
The present invention is described in detail below in conjunction with the specific embodiment.
A kind of wool fibre cladded yarn preparation method, carries out twice wool fibre and coats as heart yarn with long filament on the heart yarn surface, the sth. made by twisting of wool fibre is to the sth. made by twisting of wool fibre when the 2nd time coats to opposite when coating for its 1st time.
Concrete steps are as follows:
Step 1: on three roller drafting mechanisms of the two-region of ring frame, wool fibre rove yarn is fed by horn mouth, and through the drawing-off of reel cage drafter; The front roller nip feeding of polyester filament from gripping converges with drafted wool fibre rove yarn;
Step 2: the twisting area of being carried feeding wool fibre rove yarn through polyester filament by front roller, polyester filament transmits by the accurate feed carrier of making, and the center of aligning wool fibre rove yarn, after converging with wool fibre rove yarn, jointly enter the twist triangle zone twisting of RING SPINNING;
Step 3: by the tension force of filament yarn tension control device control long filament, tension value is controlled between 20cN~40cN, fibre bundle in the wool fibre rove yarn after long filament and the drawing-off is at the coaxial composite twist of yarn twist triangle zone, long filament is carried out the 1st wool fibre coat twisting, its twist factor that coats twisting is 220~280;
Step 4: the cladded yarn that step 3 is made, carry out the 2nd wool fibre according to step 1~3 and coat twisting, namely obtain the wool fibre cladded yarn, the twist factor that coats twisting is 220~280, and the 2nd wool fibre coats the sth. made by twisting that cladded yarn applied with the 1st wool fibre coating to opposite.
Utilize polyester filament Core Yarn Percentage 20%~35% in the wool fibre cladded yarn that said method makes, the outsourcing wool fibre is 65%~80%.
From the principle aspect inventive point of the present invention is described:
It is exposed that the outsourcing staple fibre of non-resilient cladded yarn produces long filament at fabric face easily, affects appearance of fabrics.The process that the present invention forms be mainly at long filament as heart yarn, pass through spinning technique, carrying out twice wool fibre on the heart yarn surface coats, and the sth. made by twisting that coats wool fibre for the 1st time to the sth. made by twisting that coats wool fibre for the 2nd time to opposite, to increase covered effect, reduction or elimination long filament heart yarn are in the exposed phenomenon of fabric face.
