Problems solved by technology

Especially when the hemp is of average quality, there are many short hemp fibers due to less long hemp fibers after combing. In the traditional spinning process, especially in the scouring process, it is not possible to control the long and short fibers in the scouring process. Therefore, it is difficult to produce high-quality products after mixing long and short fibers. Therefore, flax and short hemp fibers can only be used to produce short hemp products, which improves the production of raw materials for spinning mills. cost

Embodiment 1

[0035] The manufacturing process of 24 public count linen yarn blending is as follows:

[0036] Selection of flax long hemp fiber raw material → combing machine → combing hemp → sliver frame → 0 draw frame → 1 draw frame → 2 draw frame → 3 draw frame → final draw frame → roving machine→scouring and bleaching pot→spinning frame→dryer→automatic winder→finished product packaging, its innovation lies in:

[0037] a. When the flax long hemp fiber raw material carding and manufacturing process passes through two drawing frame processes, the combed flax short hemp fiber slivers made by carding and finishing the flax short hemp fiber raw material production line are added to the flax long hemp spinning process , when adding, select the middle front position of each feeding hemp sliver to feed, and at the same time, the feeding guide sheet spacing is set as 35mm; the flax short hemp fiber raw material production line is the flax short hemp fiber raw material→combined carding machine→ ...

Embodiment 2

[0070] The different parts in the manufacturing process of the blended spinning of 28 common count flax yarns and the manufacturing process of embodiment 1 are as follows

[0071] In drawing process:

[0072] Number of channels Draft multiple Bar weight (g) Combined number Feeding guide piece width (mm) Remark Second draw frame 10.627 13.5 8 32 Add short hemp strips after this process machine Three draw frames 10.284 11.22 8 28 Four draw frame 9.159 4.9 4 22 Roving 9.94 0.5 1 18

[0073] The specific parameters of the pre-light bleaching process described in the boiling and bleaching process are: the pre-light bleaching solution contains sulfuric acid (H 2 SO 4 ) 2.7 g / L, sodium chlorite (N a CLOs 2 ) 1.7 g / L, sodium nitrate (NaNO 3 ) 1 g / L and penetrant (JFC) 1.3 g / L aqueous solution; keep warm for 50 minutes at 45°C;

Abstract

The invention provides a linen blend manufacturing process, comprising the following steps of using long linen flax fiber as raw materials, and subjecting long linen flax fiber to a hackling machine, hackling into long linen, subjecting to a strip forming machine, a zero drawing machine, a first drawing machine, a third drawing machine, a final drawing machine, a roving machine, a scouring and bleaching pot, a spinning machine, a dryer, and an automatic winder in sequence, and packaging of finished products. The linen blend manufacturing process is characterized in that the combed short linen flax fiber strips, which are combed and refined on a short linen flax fiber raw material production line, are added to a long linen spinning process; meanwhile, the pre-light bleaching and twice bleaching technology is adopted in the scouring and bleaching process; and the linen blended yarns spun produced by the linen blending manufacture process solve the long-standing problem that how the good short linen flax fibers hackled by the hackling machine return to the long linen flax fibers to be spun, thus not only reducing costs but also spinning high-quality linen blended products.

Description

technical field [0001] The invention belongs to textile manufacturing technology, in particular to a linen blending manufacturing technology. Background technique [0002] At present, in the production process of flax, the long and short hemp fibers follow different production process routes separately, and the produced long hemp fiber products and short hemp fiber products are also very different in quality and value. Generally, long hemp fiber products in the market The sales price of products produced separately from short fiber and short fiber is at least 5,000 yuan per ton. Especially when the hemp quality is average, there are many short hemp fibers due to less long hemp fibers after combing. In the traditional spinning process, especially the scouring process, it is not possible to control the long and short fibers in the scouring process. Therefore, it is difficult to produce high-quality products after mixing long and short fibers. Therefore, flax and short hemp fi...
