Problems solved by technology

[0003] Wool fiber generally used in textiles refers to sheep wool fiber. For goat hair, it is the leftovers of cashmere carding process. The carded cashmere is used for the production of high-end textiles, and the carded goat hair , except that a small amount is used to make brushes, most of them are discarded as waste, because: the goat hair fiber has high rigidity, thick diameter, large discrete length, smooth surface and almost no curl, etc., which leads to the use of traditional weaving It is very difficult for the equipment to carry out spinning processing, so goat hair is rarely used for spinning processing, which causes a waste of goat hair resources

Embodiment 1

[0065] Take clean goat hair (to remove impurities and oil stains), first add water and hair oil-spindle oil to the clean goat hair, and then open and mix the clean goat hair in sequence; wherein, the amount of water added is controlled to be able to Keep the moisture regain of goat hair on the machine at 20%, and the total oil content after kneading is 1%. In order to make the goat hair fully absorb water and oil, it can be stuffed after mixing. The time of stuffing is controlled as 8h, the temperature is normal temperature;

[0066] The obtained pretreated goat hair is carded by a roller carding machine with a fiber messy mechanism, and the fiber web is output from the carding machine doffer;

[0067] Carry out cross-laying on the obtained fiber web, so that the fiber layer after laying becomes thicker, and the square meter weight meets the requirements of carpet design, generally at 500g / m 2 above;

[0068] The fiber web formed by cross-laying is needle-punched to form a g...

Embodiment 2

[0070] Get clean goat hair (to remove impurities and oil stains), first add water and hair oil-castor oil to the clean goat hair, then open and mix the clean goat hair successively; wherein, the amount of water added is controlled to be able to Keep the moisture regain of goat hair on the machine at 22%, and the total oil content after blending is 1.5%. In order to make the goat hair fully absorb water and oil, it can be stuffed after mixing. The time of stuffing is controlled as 12h, the temperature is normal temperature;

[0071] The obtained pretreated goat hair is carded by a roller carding machine with a fiber messy mechanism, and the fiber web is output from the carding machine doffer;

[0072] Carry out cross-laying on the obtained fiber web, so that the fiber layer after laying becomes thicker, and the square meter weight meets the requirements of carpet design, generally at 500g / m 2 above;

[0073] The fiber web formed by cross-laying is needle-punched to form a goa...

Embodiment 3

[0075] Get clean goat hair (to remove impurities and oil stains), first add water and hair oil-castor oil to the clean goat hair, then open and mix the clean goat hair successively; wherein, the amount of water added is controlled to be able to Keep the moisture regain of the goat hair on the machine at 25%, and the total oil content after kneading is 2%; in order to make the goat hair fully absorb water and oil, it can be stuffed after mixing, and the time of stuffing is controlled as 15h, the temperature is normal temperature;

[0076] The obtained pretreated goat hair is carded by a roller carding machine with a fiber messy mechanism, and the fiber web is output from the carding machine doffer;

Abstract

The invention discloses a processing method of a goat hair needle-punched nonwoven carpet. The processing method comprises using goat hair or a goat hair main body added with a certain proportion of hot melt fiber as a processing raw material, adding water and wool oil to the processing raw material, and then successively performing opening, mixing and wool covering treatment on the processing raw material; performing carding by using a carding machine, and outputting fiber webs from a card doffer; performing cross lapping on the obtained fiber webs; performing needle-punched reinforcing on the fiber web formed by cross lapping, and forming a goat hair needle-punched nonwoven fabric; and disposing the goat hair needle-punched nonwoven fabric in a drying oven to perform drying treatment, naturally cooling the goat hair needle-punched nonwoven fabric to room temperature after drying is completed, and obtaining the goat hair needle-punched nonwoven carpet. According to the processing method, the goat hair fiber is processed and manufactured by using a needle-punched nonwoven technology, and the goat hair fiber can be well utilized.

Description

technical field [0001] The invention belongs to the technical field of non-woven textile processing, and in particular relates to a processing method of goat hair needle-punched non-woven carpets. Background technique [0002] Non-woven fabric, also known as non-woven fabric, is a kind of fabric formed without spinning and weaving. The formation process is generally as follows: firstly, the short textile fibers or filaments are oriented or randomly arranged to form a web structure, and then used Reinforced by mechanical, thermal or chemical bonding methods. Non-woven fabrics produced by non-woven technology have the advantages of short production process and low production cost. [0003] Wool fiber generally used in textiles refers to sheep wool fiber. For goat hair, it is the leftovers of cashmere carding process. The carded cashmere is used for the production of high-end textiles, and the carded goat hair , except that a small amount is used to make brushes, most of them...
