Problems solved by technology

However, the hemp referred to covers a wide range, such as ramie and flax, which can be processed with traditional textile equipment without pre-flowering treatment, which will cause great damage to the hemp fiber and cause fracture. In addition, the calendering and shaping process adopted is also relatively complicated, resulting in rising production costs
[0006] Looking at the existing documents and materials, the hemp non-woven fabric material tends to be thick and heavy, and the hemp fiber used is mainly jute. Because jute exists in a state of bundled fibers, and the fiber length is uneven, it is difficult to spin with existing textile equipment. Yarn and weaving, when processing non-woven materials, it is also difficult to adopt the production method of making fine and soft spunlace non-woven fabrics, but mainly adopts the acupuncture processing method, which has the characteristics of thick and stiff The characteristics of its application are mainly in the field of automotive materials, and the application in the field of home textiles is limited

Embodiment 1

[0026] The main length of ramie combed noil fiber is 35mm, the fineness is 3.5dtex, the length of polylactic acid bicomponent fiber is 51mm, the fineness is 2.2dtex, and the mixing ratio of the two is 85:15. Firstly, the ramie nodding is pretreated, and the nodding is directly manually fed from the cotton box behind the old carding machine. The nodding is beaten into hemp rolls before the machine, and the hemp rolls are further sprayed with Taikoo oil. The amount of Taikoo oil is the weight of the hemp rolls. 5%, and then covered with plastic cloth for 24 hours for soft treatment, so that the moisture regain of the hemp roll can reach 15%. The treated hemp rolls and PLA bi-component fibers are manually fed into the cotton feeding box through the machine, and are softly opened, mixed, carded and spunlace reinforced. The main process parameters are: the cylinder speed is 710 m / min, The working roll speed is 41.6 m / min, the stripping roll speed is 135.3 m / min, the random roll spe...

Embodiment 2

[0036] The main length of ramie combed noil fiber is 40mm, the fineness is 4.0dtex, the length of polylactic acid bicomponent fiber is 51mm, the fineness is 4.4dtex, and the mixing ratio of the two is 80:20. According to the method of Example 1, the ramie nodding is pretreated, so that the moisture regain of the hemp coils reaches 18%. The main process parameters of spunlace processing are: cylinder speed is 680 m / min, work roll speed is 38.6 m / min, stripping roll speed is 126.5 m / min, random roll speed is 823 m / min, doffer speed is 14.9 m / min, using 6 spunlace processes, the pre-wet water pressure is 2bar, the second to sixth main spunlace pressures are: 25bar, 55bar, 75bar, 88bar, 66bar, and the production line speed is 24.3m / min. The dipping and rolling impregnation solution is used to form a surface modification layer, the rolling rate is controlled at 75%, and the drying temperature after padding is controlled at 130°C. The components in the finishing solution are: 99.5...

[0044] The main length of ramie combed noil fiber is 35mm, the fineness is 3.5dtex, the length of polylactic acid bicomponent fiber is 51mm, the fineness is 4.4dtex, and the mixing ratio of the two is 85:15. The ramie nodding is pretreated according to the method of Example 1, so that the moisture regain of the hemp coils reaches 15%. The main process parameters of spunlace processing are: cylinder speed is 790 m / min, work roll speed is 50.1 m / min, stripping roll speed is 141.9 m / min, random roll speed is 910 m / min, doffer speed is 18.9 m / min, using 6 spunlace processes, the pre-wet water pressure is 1bar, the second to sixth main spunlace pressures are: 20bar, 50bar, 68bar, 76bar, 56bar, and the production line speed is 31.8m / min. The dipping and rolling impregnation solution is used to form a surface modification layer, the rolling rate is controlled at 86%, and the drying temperature after padding is controlled at 120°C. The components in the finishing solution are: 99.5%...

Abstract

At present, natural fibrilia non-woven fabric materials are partial to a heavy type, and are mainly applied to the field of materials for automobiles, but the application of the natural fibrilia non-woven fabric materials to the field of home textiles is limited. The invention provides a semi-durable ramie nonwoven material for the home textiles, which comprises a matrix material and a surface modification layer formed by padding the matrix material in finishing liquid, wherein the matrix material comprises the following components in percentage by mass: 80 to 90 percent of ramie combed noil fibers and 10 to 20 percent of polylactic acid bi-component fibers; the finishing liquid comprises the following components in percentage by mass: 97.5 to 99.4 percent of polyacrylate bonding agent, 0.2 to 1.5 percent of hydrophilic organic silicon softening agent and 0.1 to 0.5 percent of penetrating agent; and the thickness of the ramie nonwoven material for the home textiles is between 0.5 and 1.5 millimeters, and the weight is between 60 and 120 grams / square meter. The semi-durable ramie nonwoven material has the functions of light weight, thinness, washability, antibacterium, acarid prevention, static resistance and ultraviolet light prevention, is soft in handfeel, and can be degraded completely after being discarded.

Description

technical field [0001] The invention relates to a non-woven material for home textiles, in particular to a fully degradable semi-durable ramie non-woven material for home textiles with functions of washability, antibacterial, anti-mite, antistatic and anti-ultraviolet light. Background technique [0002] Existing home textiles such as bed sheets, quilt covers, pillowcases, tablecloths and curtains are all made of woven fabrics (woven fabrics). Due to the long process of spinning, weaving into cloth and subsequent finishing, the woven fabrics are relatively strong. Durable and not easy to break, the service life is generally 3 to 7 years, but home textile products, especially bedding, are only washed by ordinary washing machines after use, and have not been sterilized by high-temperature cooking, especially after long-term use, they are prone to breed bacteria and mites, which bring great hidden dangers to human health, so the concept of semi-durable home textile products cam...
