Embodiment 1

[0030] A kind of mechanical finishing method of woolen fabric:

[0031] Select 46Nm / l primary color 45 / 55 wool polyester yarn to weave on the circular knitting machine of 24G 30 ":

[0032] (1) In order to make the fabric bonded more closely and have a wool feeling after acupuncture finishing, choose 46Nm / l primary color 45 / 55 wool polyester yarn;

[0033] (2) 24G 30″ circular knitting machine is used for weaving. In order to make the fabric softer, the length of the loop is appropriately increased to 1.2mm, and weaving is carried out with flat needles;

[0034] (3) After the gray cloth is off the machine, it is boiled to remove impurities. The temperature of the boiled cloth can be controlled at about 50°C, and then rinsed with water at room temperature, then water is added at a bath ratio of 1:10-1:20, and then 1.5%- 4% (o.w.f) of silicone softener and 0.5%-2% (o.w.f) of antistatic agent, after 10-20 minutes of treatment, dehydration and drying;

[0035] (4) Acupuncture fi...

Embodiment 2

[0038] Select 32Nm / l navy blue 30 / 70 wool acrylic yarn, 46Nm / l royal blue 50 / 50 wool acrylic yarn to weave on the circular knitting machine of 22G 30 ":

[0039] (1) select 32Nm / l dark blue 30 / 70 wool acrylic yarn, 46Nm / l royal blue 50 / 50 wool acrylic yarn to arrange in a mode of one by one, and weave on the circular knitting machine of 22G 30 ";

[0040] (2) In order to make the fabric softer, the length of the coil is appropriately increased to 1.2mm, and the beaded weave is used for weaving;

[0041] (3) After the gray cloth is off the machine, it is boiled to remove impurities. The temperature of the boiled cloth can be controlled at about 60°C, and then rinsed with water at room temperature, then water is added at a bath ratio of 1:10-1:20, and then 2%- 4% (o.w.f) of silicone softener and 0.5%-2% (o.w.f) of antistatic agent, after 10-20 minutes of treatment, dehydration and drying;

[0042] (4) Acupuncture finishing is performed on the fabric after soft finishing; three ...

Abstract

The invention discloses a mechanical finishing method for a wool fabric. The mechanical finishing method for the wool fabric is characterized by comprising the following steps: selecting a yarn, wherein the quantity of the yarn is 32 Nm / l to 58 Nm / l and the wool content of the yarn is 7%-100%; determining the type of a weaving machine and the weaving parameter according to the selected yarn; feeding a gray fabric into the weaving machine, boiling the fabric, removing an impurity, washing with water, conducting softening finishing by adding a silicone softener and an antistatic agent; mechanically finishing by using the combination of three needling machines; and finally shearing the fabric. The provided wool fabric finished through the needle punching technology adopts the combination of three needling machines in the needling processing process, the first needling machine chooses a thinner felting needle to slantly needle downwards, the second needling machine chooses a thicker felting needle to vertically oppositely needle on the same site, and the third needling machine chooses a thinner felting needle to vertically needle upwards, so that the fabric is more sufficiently needled and is higher in air permeability while the processing efficiency is improved.

Description

technical field [0001] The invention relates to a method of finishing gray cloth containing wool by using a needle-punching process to form a fabric with a shrinking effect, which belongs to the technical field of woolen clothing fabrics. Background technique [0002] In recent years, with the development of social economy and the improvement of living standards, people's requirements for textiles are gradually developing in the direction of high quality, modernization, comfort and technology. Because people have various requirements for individualization and diversification of textiles, the speed of textile replacement is getting faster and faster, and new fibers, new yarns, and new processes have been developed rapidly. [0003] Wool is a kind of natural animal protein fiber. Due to the disulfide bonds and more hydrophilic groups between the macromolecular chains, the fiber has large curls, is soft and elastic, has strong hygroscopicity and good warmth retention. The use ...
