Description

Cashmere and Lyselle blended fabric

technical field

The invention relates to a fabric, in particular to a fabric blended with cashmere fiber and Lisa fiber.

Background technique

Cashmere is a thin layer of fine velvet that grows on the outer skin of goats and covers the roots of goats' coarse hair. It grows out when it is cold in winter to resist the wind and cold. It falls off after the warming of spring and naturally adapts to the climate. It is a rare special animal fiber. The reason why cashmere is very precious is not only due to the scarcity of output (accounting for only 0.2% of the world's total animal fiber production), but more importantly, its excellent quality and characteristics. "Fiber Queen" is incomparable to all the textile materials currently available to human beings, so it is also called "soft gold".

Cashmere has irregular thin and deep curls, composed of scale layer and cortex layer, without medulla layer, the scale density is about 60-70/mm, the fiber cross section is approximately circular, and the diameter is thinner than fine wool. The average fineness is mostly 14-16um, the fineness unevenness is small, about 20%, and the length is generally 35-45mm. It is thin, light, soft, smooth and warm. The fibers are moderately strong, elastic and have a natural soft color.

Richcel fiber, also known as Richcel fiber, is a Polynosic fiber produced by Japan Toyobo's proprietary technology and raw material system. It is a plant cellulose fiber with excellent comprehensive properties. The raw material of Lisai fiber comes from the refined wood pulp of natural coniferous trees imported from Japan. The resources are renewable, and the waste can be degraded naturally, which is safe and environmentally friendly. Lisai fiber has high strength, high wet modulus, high degree of polymerization and appropriate elongation, good hygroscopicity, and is close to Tencel fiber in performance; while the market price is much lower than Tencel fiber, and is closer to Modal. Lisai fiber fabric has better dimensional stability, less shrinkage, more washable and durable; bright color, good drape; Lisai fiber has good alkali resistance, and can be mercerized with cotton blended fabrics to improve fabric Feel and gloss. Therefore, Lisai fiber not only meets the requirements of "sustainable development", but also meets the fashion needs of people's increasing pursuit of nature, comfort, beauty and health care, and has a very good market prospect.

The present invention attempts to blend cashmere fibers and Lisa fibers by providing a new blended fabric.

Contents of the invention

Aiming at the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a fabric blended with cashmere fiber and Lisa fiber.

In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions:

A blended fabric of cashmere fiber and Lisa fiber is made of 20-40wt% cashmere fiber and 60-80wt% Lisa fiber.

Preferably,

A cashmere fiber and Lisa fiber blended fabric is made of 20-40wt% cashmere fiber and 60-80wt% Lisai fiber blended fabric, and then finished after antibacterial finishing.

The antibacterial finishing step is to immerse in the antibacterial finishing solution at room temperature for 10-30 minutes, the amount of antibacterial finishing agent in the antibacterial finishing solution is 0.5-1.5% o.w.f, and the bath ratio is 1:15-1:25.

The antibacterial finishing agent is composed of the following components by weight: 5-15 parts of protamine sulfate, 50-70 parts of 2,4,4'-trichloro-2'-hydroxydiphenyl ether, 50-70 parts of dodecyl 5-15 parts of dimethyl betaine, 15-25 parts of polyhexamethylene biguanide hydrochloride. The antibacterial finishing agent can be prepared by stirring and mixing the above-mentioned components evenly.

Specifically, in the present invention:

Protamine sulfate, pinyin name: Liusuan Yujingdanbai, English name: ProtamineSulfate, page number: Chinese Pharmacopoeia 2005 Edition II-742, this strain is a kind of basic protein sulfate extracted from fresh mature sperm of suitable fish . Calculated as dry product, it is white or off-white powder, odorless, hygroscopic, soluble in water, insoluble in ethanol, chloroform or ether.

2,4,4'-Trichloro-2'-hydroxydiphenyl ether, alias: Yujiexin, Triclosan, abbreviated as DP300, English name: 5-chloro-2-(2,4-dichlorophenoxy), CAS number : 3380-34-5.

Lauryl dimethyl betaine, CAS number: 683-10-3.

Polyhexamethylenebiguanide hydrochloride, English name: Poly(hexamethylenebiguanide) hydrochloride, CAS accession number: 32289-58-0.

o.w.f, the full name is On weight the fabric, a term for textile dyeing and finishing. The concentration in the textile dyeing and finishing process is based on the weight of the fabric, relative to the percentage of the fabric.

Bath ratio, liquor ratio, a term used in textile dyeing and finishing, refers to the ratio of fabric to dye liquor in the dipping method.

It should be noted that, unless otherwise specified in the present invention, the content of each raw material is 100%.

In the present invention, protamine sulfate, a raw material commonly used in medicine and food industry, is applied to textile antibacterial treatment. Further, in the present invention, protamine sulfate and antibacterial agent 2, 4, 4'-tri Chloro-2'-hydroxydiphenyl ether and polyhexamethylene biguanide hydrochloride are used in combination, and under the synergy of surfactant dodecyl dimethyl betaine, the antibacterial effect is obviously enhanced.

Compared with the prior art, the remarkable progress of the technical solution of the present invention is mainly reflected in the following: the present invention mixes cashmere fiber and Lisai fiber with different properties to complement each other, and the fabric is slender, light and thin, warm and elastic, and comfortable to wear . Furthermore, through antibacterial finishing, the fabric has a high antibacterial rate, which can effectively protect human health.

Detailed ways

Example 1

Select commercially available cashmere fiber and Lisa fiber, and the mass ratio is 30:70.

The cashmere fiber weighed according to the above ratio is opened and pretreated, and carded into a raw sliver on the carding machine; the Lisa fiber weighed according to the above ratio is opened and pretreated, and carded into a raw sliver on the carding machine; Combining cashmere fiber raw sliver and Lisa fiber raw sliver on the drawing frame to make mature sliver; drafting and twisting on the roving frame, and finally further drafting and twisting on the spinning frame to make Lisa fiber and cashmere fiber blend spinning. Then, the blended yarn of the Lisai fiber and the cashmere fiber is woven by a large circular machine weft knitting method, and finally a fabric blended with the cashmere fiber and the Lisai fiber is obtained.

Obviously, the above-mentioned preparation techniques of blended yarns and fabrics are common methods in this industry and are well known to those skilled in the art.

Example 2
