Problems solved by technology

However, the sticky substances between the fibers in the flax raw material, the flax bone after the flax is opened, the short pile and the ultra-long fibers contained in the hemp increase the difficulty of blending.
So far, no industrially applicable flax blended yarn process has been disclosed

Embodiment 1

[0034] (1) Raw materials

[0035] By weight: 55 parts of linen, 25 parts of cotton, 20 parts of cashmere;

[0036] (2) Yarn count: 32Nm / 2D;

[0037] (3) Process flow:

[0038] (1) Loose fiber, dyeing and oiling of flax;

[0039] In view of the characteristics of flax with many short piles, parallel threads, and many bones, the flax is degummed before dyeing, mainly to remove the hemp skin in the flax raw material and increase the fiber opening performance. The existing degumming enzyme is used to press the The prior art of enzymatic degumming in this field destroys the cohesive substances between fibers, makes the fibers into a single state, and increases the performance of spinning and carding. Add 4-5% flax special softener DT-150cp by weight during the health care treatment after dyeing to improve the hand feeling of dyed flax, make it soft and improve spinnability. Refueling and health preservation: According to the condition of dyed flax fiber, add an appropriate amou...

Embodiment 2

[0056] (1) Raw materials

[0057] Proportion by weight: 15 parts of flax, 45 parts of spun silk, 40 parts of tencel;

[0058] (2) Yarn count: 80Nm / 2D;

[0059] (3) Process flow:

[0060] Step (1) is with embodiment 1;

[0061] Step (2) Add antistatic agent to spun silk and tencel for health preservation; use FK-301 type antistatic agent, and control the antistatic agent between 0.7% and 1.4% by weight.

[0062] Step (3) Synthesize the flax, spun silk and tencel after health preservation; because the flax content is below 30%, the method of pseudo-synthesis should be adopted, first flax is mixed with 10% spun silk and 10% tencel, according to Mix evenly, mix 2-3 times, then use it as a group, and then mix it with the remaining silk and tencel so that the raw materials can be mixed evenly.

[0063] All the other steps are the same as in Example 1.

[0064] (4) main technological parameter, as embodiment 1, difference is:

[0065] Cleaning process: the weight of cotton laps...

Embodiment 3

[0070] (1) Raw materials

[0071] Proportion by weight: 20 parts of flax, 50 parts of viscose, 30 parts of acrylic fiber;

[0072] (2) Yarn count: 48Nm / 2D;

[0073] (3) Process flow:

[0074] Step (1) is with embodiment 1;

[0075] Step (2) dyeing viscose and acrylic fibers;

[0076] Step (3) blend the flax after health preservation and dyed viscose and acrylic fiber; because the flax content is below 30%, adopt the method of pseudo-synthesis, first flax is mixed with 10-20% viscose and acrylic fiber, according to Mix evenly, mix 2-3 times, then use it as a group, and then mix it with the rest of the viscose and acrylic fiber, so that the raw materials can be mixed evenly.

[0077] All the other steps are the same as in Example 1.

[0078] (4) main technological parameter, as embodiment 1, difference is:

[0079] Cleaning process: the weight of cotton laps is 9.5kg / piece, and the weight per meter is 380g.

[0080] Carding process: the cylinder-flat five-point gauge is 0...

Abstract

The present invention involves a processing method of semi-worsted flax blended yarn, and it belongs to flax blended yarn technical field. The counts of the semi-worsted flax blended yarn is 30-85 Nm / 2D, the raw materials consists of flax 10-60 and other fiber 40-90; degelatinizing, dyeing and preserving flax, pretreating other fiber, then putting together wool, blowing cotton, carding and drawing, then prespinning and shirting, last the products are prepared after cheese winding, twisting and double twisting processes. The invention combines the 'straight' of flax fiber and the 'softness' of other fibers effectively; the prepared semi-worsted flax blended yarn has many advantages of good textile strands and less granulite, it is suitable for the face fabric of thin summer inner wear and coat.

Description

technical field [0001] The invention belongs to the technical field of flax blended yarn, and in particular relates to a processing method of semi-worsted flax blended yarn. Background technique [0002] In recent years, as the domestic and foreign textile markets return to nature, green textiles have become the new favorite of the textile market. Natural fibers are favored by consumers for their good wearing comfort, health care functions and improved dyeing properties. Flax is a relatively noble fiber among natural fibers. It has good moisture absorption and release properties. Its fabric is crisp and comfortable to wear. Due to the characteristics of flax fiber itself, such as many flax particles, high rigidity, and low elasticity, the development of flax yarn is limited. Other fibers such as spun silk have the advantages of softness, silvery luster, good fiber elasticity, and good dyeability. Therefore, products blended with flax and other soft fibers can reduce some sho...
