Abstract

The invention discloses a method for producing dyed linen yarns by using roves, which is characterized by comprising the following production steps: (1) putting roves into a boiler kier to perform continuous boiling, bleaching, dyeing and drying so as to obtain dyed roves; and (2) directly spinning the dyed roves on a flax spinning frame to obtain the dyed linen yarns. The method has the advantages of low production cost and high qualification rate of the dyed linen yarns.

Description

A kind of method of producing dyed linen yarns with rove

Technical field

The utility model relates to a kind of production method of producing dyed linen yarns with rove.

Background technology

Traditional production dyed linen yarns generally is to spin the finished product yarn earlier must be processed into reeled yarn through other source mill then, dyes or become loose formula bobbin and then cross dyeing cotton mill to dye through winder earlier on the finished product yarn in last cross dyeing cotton mill.The cost that above-mentioned production technology has not only increased operation but also increased production cost greatly and had enough to meet the need repeatedly and transport, so production cost height, simultaneously because the shortcoming of technology is difficult to accomplish solid colour, so product percent of pass is not high.

Summary of the invention

Purpose of the present invention is exactly to solve with rove to produce dyed linen yarns production cost height, problem that product percent of pass is not high.

The technical solution used in the present invention is: a kind of method of producing dyed linen yarns with rove is characterized in that it comprises following production stage:

(1) rove is put into boil to float and carried out continuous kiering, bleaching, dyeing, drying in the pot, make the dyeing rove;

(2) the dyeing rove is directly spinned on flax spinning frame, promptly make dyed linen yarns.

Adopt technique scheme, it is opposite with normal yarn dyeing flow process, it is to dye earlier to spin then, owing to be very loose rove directly to be carried out dyeing earlier afterwards spin, so the characteristics of dyed yarn are solid colours inside and outside the yarn, COLOR FASTNESS is good, and gloss is soft, and colour stability is good, and can be mass-produced (because the pot capacity of flax is big, every pot of yarn can dye 1.1 tons of yarns), reduced the color distortion between each batch yarn, look is knitted more oversimplified, greatly reduce the cost of producing and transporting, reduced a lot of production links, it is simple changing complexity, achieves many things at one stroke.

The invention has the beneficial effects as follows: because adopting to dye afterwards earlier, the present invention spins, so the inside and outside solid colour of the inside and outside color yarn of yarn, COLOR FASTNESS is good, and gloss is soft, and colour stability is good, the qualification rate height of product; Because invention greatly reduces the cost of producing and transporting, and reduced a lot of production links, so production cost is lower.The present invention also can be mass-produced.

The specific embodiment

A kind of method of producing dyed linen yarns of the present invention with rove, it comprises following production stage:

(1) rove is put into boil to float and carried out continuous kiering, bleaching, dyeing, drying in the pot, make the dyeing rove;

(2) the dyeing rove is directly spinned on flax spinning frame, promptly make dyed linen yarns.

Claims (1)

1. method of producing dyed linen yarns with rove is characterized in that it comprises following production stage:

(1) rove is put into boil to float and carried out continuous kiering, bleaching, dyeing, drying in the pot, make the dyeing rove;

(2) the dyeing rove is directly spinned on flax spinning frame, promptly make dyed linen yarns.
