Description

Pineapple fiber and anti-pilling acrylic blend fabric

technical field

The invention relates to a fabric, in particular to a fabric blended with pineapple fiber and anti-pilling acrylic fiber.

Background technique

Pineapple fiber is pineapple leaf fiber, also known as pineapple hemp, which is a fiber extracted from pineapple leaves and belongs to leaf hemp fiber. Pineapple fiber is tightly combined by many fiber bundles, and each fiber bundle is composed of 10-20 single fiber cells. The fiber surface is rough, with longitudinal gaps and holes, and horizontal branches without natural distortion. The monofilament cells are cylindrical, with pointed ends, smooth surface, and a linear lumen. Pineapple fiber is white in appearance, soft and smooth, and feels like silk, so it is also called pineapple silk. After deep processing, the pineapple fiber has a white appearance, soft and smooth. The specific raw material can be the pineapple fiber provided by Qimen Tianan Textile and Garment Co., Ltd.

The performance of anti-pilling acrylic is very similar to that of wool. It has good elasticity. When it is stretched by 20%, the rebound rate can still maintain 65%. It is fluffy, curly and soft, and its warmth retention is 15% higher than that of wool. The strength is 22.1-48.5cN/dtex, which is 1-2.5 times higher than that of wool. It has excellent light fastness. After being exposed to the open air for one year, the strength will only decrease by 20%. moth and other advantages.

Most synthetic fibers suffer from the phenomenon of "pilling" during use. Since the strength of acrylic fiber is much higher than that of natural fibers and regenerated cellulose fibers, and the formation rate of fiber pellets on the surface of its products is greater than the rate of shedding, these fiber pellets formed when friction cannot eliminate the fiber pellets The particles will remain on the surface of the fabric for a long time, thus affecting the appearance and wearing comfort of the fabric. The anti-pilling acrylic fiber uses physical modification methods to change the fiber structure and properties by adjusting the production process. On the premise of ensuring good spinnability, the fabric achieves the effect of anti-pilling. The specific anti-pilling acrylic fibers can be selected from the anti-pilling acrylic fibers produced by China National Petroleum Corporation, Jilin Qifeng Chemical Fiber Co., Ltd., and Sinopec Shanghai Petrochemical Co., Ltd., with a fineness of 0.8-2.2dtex and an average length of 38mm. Series 3.5-4.

The present invention attempts to blend pineapple fiber with anti-pilling acrylic 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 pineapple fiber and anti-pilling acrylic fiber.

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

The invention relates to a blended fabric of pineapple fiber and anti-pilling acrylic fiber, which is made of 20-40wt% pineapple fiber and 60-80wt% anti-pilling acrylic fiber blended fabric.

Preferably,

The invention discloses a blended fabric of pineapple fiber and anti-pilling acrylic fiber, which is made of 20-40wt% pineapple fiber and 60-80wt% anti-pilling acrylic fiber, 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, methyl coconut oil 5-15 parts of sodium acyl taurate, 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.

Sodium Methyl Cocoyl Taurate, CAS No.: 12765-39-8.

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 the surfactant methyl cocoyl taurate sodium, the antibacterial effect is significantly enhanced.

Compared with the prior art, the significant progress of the technical solution of the present invention is mainly reflected in the following: the present invention mixes two fibers with different properties, pineapple fiber and anti-pilling acrylic fiber, learn from each other, and the fabric is soft, smooth, bulky, easy to dye, Bright color, light fast and not afraid of insects. Furthermore, through antibacterial finishing, the fabric has a high antibacterial rate, which can effectively protect human health.

Detailed ways

Example 1

Commercially available pineapple fiber and anti-pilling acrylic fiber are selected, and the mass ratio is 30:70.

The pineapple fibers weighed according to the above ratio are opened and pretreated, and carded into raw sliver on the carding machine; the anti-pilling acrylic fibers weighed according to the above ratio are opened and pretreated, and carded into raw sliver on the carding machine; Then the pineapple fiber raw sliver and the anti-pilling acrylic raw sliver are combined on the drawing frame to make mature sliver; drafting and twisting are carried out on the roving frame, and finally further drafting and twisting are carried out on the spinning frame to make anti-pilling acrylic fiber and Pineapple fiber blend yarn. Then the anti-pilling acrylic fiber and pineapple fiber blended yarn is woven by a large circular machine weft knitting method, and finally the pineapple fiber and anti-pilling acrylic fiber blended fabric 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.
