Description

True silk/synthetic fiber wick silk and manufacturing technique thereof

The invention belongs to a kind of looping silk thread and manufacturing technique thereof.

Real silk before the present invention/close fine two component silk thread generally adopts two-step process to make, and as in 1984 second phase of " silk " magazine 23 pages of disclosed technology, the first step becomes raw silk to the silk cocoon reel silk from cocoons earlier.Second goes on foot some raw silk loopings to the fiber-synthesizing filament heart yearn.The weak point of making bag core silk in this way is: operation is many, only is suitable for the heavy denier product, and the heart yearn of this bag core silk has the twist.Surface coating layer is coarse, and screw thread is more obvious, and the coverage rate of real silk is lower.Disclose one-step method on 23 pages of Soviet Union's " silk " magazine in 1982 third phases and produced real silk/the close technology of fine compound silk.Promptly in silk reeling process directly real silk with to close fibril compound.But the product that this method obtains is a kind of real silk/close, and fine two components mix filature.Real silk can not form clad around closing fibril.

At in the past real silk/close the deficiency on fine looping silk and the manufacturing technique thereof, the present invention proposes a kind of is clad by some real silk single fibers.Fiber-synthesizing filament is bag core silk and its one-step method manufacturing technique of heart yearn.

The said bag core of the present invention silk, its skin is made up of the real silk single fiber.Because the diameter of real silk single fiber and bending stiffness are all little than raw silk, so can be used for the coating of more fine-titred heart yearn, help improving looping density, on technology, be convenient in silk reeling process, directly make bag core silk as clad with the real silk single fiber.For making the real silk single fiber can around fiber-synthesizing filament, form clad.Mainly taked following measure on technology, fiber-synthesizing filament is done continuously the widely different motion of revolving in output procedure.By silk collection thread device the time and the silk combination.The widely different speed and the output speed ratio of revolving of control fiber-synthesizing filament.Guarantee that silk reels out length and exports length greater than fiber-synthesizing filament, make the real silk single fiber be wrapped in fiber-synthesizing filament widely different the revolving under the effect of fiber-synthesizing filament wire body.The formation spiral coats.Regulate the bag core silk that this speed ratio can obtain different coverage rates.When making clad with a single fiber, the unwinding of more easily loosening, the coating fastness is low.So generally adopt three above single fibers looping together.Make and form interlaced covering between each single fiber naturally.Guarantee to coat fastness.Revolving motion owing to the looping motion dependence fiber-synthesizing filament of real silk single fiber is widely different finishes.So revolving motion, fiber-synthesizing filament widely different be absolutely necessary.In order to guarantee that fiber-synthesizing filament is not twisted in technical process, in the whole service process of fiber-synthesizing filament, adopted the mode of rolling and carrying, hold characteristics with elimination.

Accompanying drawing is a process flow diagram of the present invention.Move back and separate spindle [1], winding spindle [16], fiber-synthesizing filament delivery roller [5] and silk collection thread device [9], bag core silk converyer [11] is respectively by the transmission mechanism transmission.Fiber-synthesizing filament [3] is separated bobbin [2] and is withdrawed from from moving back under the effect of delivery roller [5], because bobbin [2] rotates with spindle [1].Make fiber-synthesizing filament that widely different revolving also be taken place.Fiber-synthesizing filament withdraws from after traveller [4] from bobbin, and delivery roller [5] and hollow pipe [6] enter collection thread device [9], and the real silk single fiber [8] on the silk cocoon [7] is inserted collection thread device [9] and fiber-synthesizing filament combination.Because the widely different of fiber-synthesizing filament revolves, the real silk single fiber forms the spiral looping on fiber-synthesizing filament.And dissociate from silkworm cocoon continuously, forming bag core silk, bag core silk [10] is wound up on the bobbin [15] through bag core silk converyer [11], hollow pipe [12], traveller [13], shaping thread guide [14], and winding bobbin [15] rotates with spindle [16].The direction of rotation of bag core silk converyer [11], spindle [16] should keep consistent with the widely different direction of revolving of strand.Can guarantee that like this strand is not twisted in the whole service process.When changing the rotating speed of delivery roller [5] or spindle [1], [16], or increase the grain number of silk cocoon [7], can change the fine content ratio of the looping density of real silk and real silk/close.Change the direction of rotation of spindle [1], spindle [16], collection thread device [9] bag core silk converyer [11].The outer real silk looping hand of spiral of bag core silk is changed, obtain " S " to or " Z " to the bag core silk of spiral looping.If spindle [1] is stopped the rotation.The widely different commentaries on classics under the effect of bag core silk converyer [11] of fiber-synthesizing filament heart yearn locates to form bag core silk at collection thread device [9].The bag core silk that is wound in this case on the bobbin [15] has the twist.

The outer field coating density of its real silk of bag core silk of the present invention can reach 100%, and the looping fastness is good, not only has the outward appearance and the sense of touch of real silk.And its brute force, the wrinkle resiliency is better than common real silk.Can save the real silk raw material with this bag core silk weaving fabric, reduce product cost.

Be one embodiment of the present of invention below.The fiber-synthesizing filament heart yearn is the polyester filament at 30 dawn, and the clad real silk is 12 real silk single fibers, promptly uses 12 silk cocoons.Spindle [1] and spindle [16] are by the tengential belt transmission, and its rotating speed is 9000 rev/mins, and the speed of delivery roller [5] is 12 meters/minute.The rotating speed of bag core silk converyer [11] is 150 rev/mins.Bag core silk is behind bag core silk converyer, under the effect of shaping thread guide, be wound up into the finished product bobbin, the fiber number of the bag core silk that this obtains was 60 dawn, brute force was 4.6 gram/dawn, the real silk clad ratio is 100%, real silk/close fine content ratio is 55: 45, and this bag core silk can be used for the various woven fabrics of weaving, knitted fabric.
