Abstract

The present invention relates to a drum treatment method of elastic yarn or fibre before which is dyed or bleached. Sid method includes the following steps: using cone winding machine to make elastic yarn or fibre roll to be dyed or bleached be winded on a large bobbin, then using mechanical equipment to take out said large bobbin and replace it with small bobbin covered with eyelet all over so as to make the yarn or fibre roll with elasticity obtain natural constraction to meet required tightness and density for dyeing or bleaching.

Description

Rotary drum treatment method before elastomeric yarn or stock-dye or the bleaching

Technical field

The present invention relates to a kind of yarn or stock-dye or bleaching processing method before, especially a kind of to the processing method before rubber-like yarn or fiber roll dyeing or the bleaching.

Background technology

At present textile industry to the processing method before yarn dyeing or the bleaching is: will wait the yarn or the fiber roll that dye or bleach, turn around with bobbin winder and to be covered with on the bobbin of eyelet, then it is enclosed within the dying on the post of dyeing machine yarn carrier, puts into cone dyeing machine and dye.Because dyeing machine is during to bobbin yarn or stock-dye, yarn or fiber bobbin are actionless, and dye liquor relies on the conveying of main pump constantly to circulate between yarn or fiber, makes on the dyestuff and dyes.Therefore, yarn or fiber turn around on bobbin must degree of tightness and density suitable, just can make dye liquor be penetrated into yarn or fiber roll inside, make the inside and outside even dyeing of yarn or fiber roll.Some special yarn or fiber use bobbin winder when the method for tube is handled such as rubber-like yarn or fiber, just are difficult to make yarn or fiber roll to reach suitable tightness.Because elastomeric yarn or fiber roll are shunk very tightly, dye liquor is not easy infiltration, does not reach the effect of inside and outside even dyeing.Though abroad some loose type coning machine can reach the effect of suitable degree of tightness to the winder of elastomeric yarn or fiber,, this loose type coning machine can not equally with common bobbin winder run up, and equipment complex operations difficulty height, and production efficiency is very low.

Summary of the invention

Coil of wire tension when overcoming common bobbin winder to rubber-like yarn or fiber winder, the dye liquor infiltration is inhomogeneous; Use the low deficiency of loose type coning machine production efficiency.The invention provides the rotary drum treatment method before a kind of production efficiency height, dye liquor permeate uniform elastomeric yarn or stock-dye or bleaching.

The present invention adopts following technical scheme to realize purpose of the present invention: at first with common bobbin winder rubber-like yarn or fiber are turned around on a big bobbin, with mechanical device big bobbin is taken out from yarn or fiber roll then, small bobbin is inserted in yarn or the fiber roll, rubber-like yarn or fiber roll will be shunk naturally with small bobbin and be cooperated again.Make elastomeric yarn or fiber roll reach desirable tightness, will be according to elastomeric yarn or elongation of fiber rate, calculate yarn on the big bobbin or fiber roll diameter and the diameter ratio that takes out after yarn behind the big bobbin or fiber roll are shunk naturally, shrink the recently definite big bobbin of diameter and the corresponding diameter of small bobbin of front and back according to yarn or fiber roll again, realize the dyeing of elastomeric yarn or fiber roll or bleach needed tightness, reach dye liquor and permeate uniform purpose.Must be covered with eyelet on the small bobbin, be convenient to the dye liquor circulation.

The invention has the beneficial effects as follows: because the processing method that has adopted big bobbin to change small bobbin before elastomeric yarn or stock-dye or the bleaching makes rubber-like yarn or fiber roll obtain natural contraction, tightness has obtained adjusting.Therefore, dye liquor can permeate evenly during to rubber-like yarn or stock-dye or bleaching, and dyeing or bleaching effect are good especially.Since used processing method of the present invention, rubber-like yarn or fiber, and dyeing or bleaching production efficiency have obviously improved, and have reached basically with common yarn dyeing or bleaching to produce same efficient.

Description of drawings

The present invention is further described below in conjunction with drawings and Examples.

Fig. 1 is the schematic diagram of embodiment 1.

Fig. 2 is the schematic diagram of embodiment 2.

The implication of each Reference numeral is among the figure: 1. manipulator, 2. yarn or fiber roll, 3. big bobbin, 4. small bobbin, 5. baffle plate, 6. push rod.

The specific embodiment

Embodiment 1:

Rotary drum treatment method is achieved in that and at first will waits the yarn or the fiber that dye or bleach before a kind of elastomeric yarn shown in Figure 1 or stock-dye or the bleaching, turns around on bobbin (3) greatly with common bobbin winder.The outer round surface of big bobbin (3) has many grooves, goes up when forming yarn or fiber roll when yarn or fiber are wrapped in big bobbin (3), between yarn or fiber roll (2) and the surperficial groove of big bobbin (3), the space will be arranged.Use manipulator (1) to insert that (manipulator is a kind of mechanical device as paw in yarn or fiber roll (2) and the space between the bobbin (3) greatly then, paw can open under dynamic action, also can close up), paw on the manipulator (1) power with under outer, strut rubber-like yarn or fiber roll (2), so just big bobbin (3) can be taken out from yarn or fiber roll (2), the small bobbin (4) that again surface is covered with eyelet is put into yarn or the fiber roll (2) that struts with manipulator, then manipulator (1) is closed up, and it is extracted out from yarn or fiber roll (2), at this moment yarn or fiber roll (2) are just shunk naturally and are cooperated with the small bobbin that is covered with eyelet (4).Owing to changed the big bobbin (3) in elastomeric yarn or the fiber roll into be covered with eyelet small bobbin (4), elastomeric yarn or fiber roll (2) have obtained natural contraction, and the diameter of big bobbin (3) and small bobbin (4) calculates according to elastomeric yarn or elongation of fiber rate, therefore, the degree of tightness of elastomeric yarn or fiber roll and density can reach required requirement.During like this to rubber-like yarn or stock-dye or bleaching, dye liquor can permeate evenly, can realize dyeing preferably or bleaching effect.

Embodiment 2:

Rotary drum treatment method is achieved in that and at first will waits the yarn or the fiber that dye or bleach before a kind of elastomeric yarn shown in Figure 2 or stock-dye or the bleaching, turns around on bobbin (3) greatly with common bobbin winder.The big surperficial smoother of bobbin (3), and certain tapering is arranged.Then, the big bobbin (3) that is wound with yarn or fiber roll is leaned against on the baffle plate (5), the bigger end of diameter is inserted in the circular hole on the baffle plate (5), be against the less end of big bobbin diameter with push rod (6), push rod (6) is released yarn or fiber roll (2) with big bobbin (3) under the effect of power.Be with the small bobbin (4) that is covered with eyelet on the push rod (6), when big bobbin (3) when being pushed out, push rod (6) is sent into small bobbin (4) in yarn or the fiber roll (2) simultaneously.At this moment yarn or fiber roll (2) are just shunk naturally and are cooperated with the small bobbin that is covered with eyelet (4), owing to changed the big bobbin (3) in elastomeric yarn or the fiber roll into be covered with eyelet small bobbin (4), elastomeric yarn or fiber roll (2) have obtained natural contraction, and the diameter of big bobbin (3) and small bobbin (4) calculates according to elastomeric yarn or elongation of fiber rate, therefore, the degree of tightness of elastomeric yarn or fiber roll and density can reach required requirement.During like this to rubber-like yarn or stock-dye or bleaching, dye liquor can permeate evenly, can realize dyeing preferably or bleaching effect.
