Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of glove lining material production, and specifically relates to a production process of a bio-based waterproof and breathable glove lining material. Background Art
[0002] In the research and development of bio-based polyamide materials (bio-based PA), commonly used renewable raw material resources include castor oil, oleic acid and linoleic acid, and glucose, etc. Among them, as the raw material of castor oil, castor beans are a fast-growing crop with a quarterly stem growth rate of up to 2m. They can be planted on barren land without competing with food crops for land. The yield of castor beans per hectare can reach about 10t, which is an excellent renewable raw material.
[0003] The technology of developing bio-based polyamide materials using castor oil is already very mature. For example, the bio-based PA610 developed by BASF uses 60% of sebacic acid from castor oil; the bio-based PA11 developed by Arkema uses castor beans as raw materials to produce 11-aminoundecanoic acid, which is polymerized in three stages to obtain poly-11-aminoundecanoic acid. According to the research and test results of the French Textile and Clothing Institute (IFTH), PA11 fibers and their fabrics have many characteristics, including high wear resistance, good chlorine resistance, good fiber flame retardancy and quick drying.
[0004] The present invention aims to apply bio-based PA11 materials to the field of waterproof and breathable glove lining materials, wherein the waterproof and breathable glove lining material refers to a glove lining material in which water does not penetrate into the glove lining material under a certain pressure, while the sweat emitted by the human body can be conducted to the outside world through the glove lining material in the form of water vapor. The waterproof and breathable glove lining material can prevent sweat from accumulating and condensing between the body surface and the glove lining material, thereby achieving the purpose of maintaining the comfort of clothing. It is a high-tech, unique functional glove lining material. The application of bio-based PA11 materials in the field of textile glove lining materials has positive application prospects. Summary of the invention
[0005] The purpose of the present invention is to provide an application method of bio-based PA11 material in the field of waterproof and breathable glove lining materials. At the same time, through the improvement of process methods and process parameters, as well as directional modification of materials, a production process of bio-based waterproof and breathable glove lining materials is finally formed.
[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0008] The PP non-woven fabric and the bio-based fiber film are laminated by high-temperature hot pressing through a laminating machine, and then cooled, shaped, cut and sewn to obtain the bio-based waterproof and breathable glove lining material;
[0009] The bio-based fiber membrane is obtained by melt spinning of bio-based polyamide material to obtain bio-based fibers; the bio-based fibers are modified by sizing with a hydrophobic modified slurry and then plain weaving to obtain the bio-based fiber membrane.

[0011] Furthermore, the gram weight of the PP nonwoven fabric is 15-25 g / m 2 The bio-based fiber membrane has a gram weight of 15-25 g / m 2 .
[0012] Furthermore, the bio-based fiber membrane is prepared by the following steps:
[0013] Step S1: putting the dried pretreated bio-based polyamide into a spinning machine for melt spinning, the temperature range of the melt spinning machine is: the temperature of the first zone is a preheating temperature of 100-105°C, the temperature of the second zone is a compression temperature of 125-130°C, the temperature of the third zone is a compression temperature of 150-155°C, and the temperature of the fourth zone is an extrusion temperature of 185°C. The screw speed of the spinning machine is controlled to be 50rpm, the drafting speed is 10m / min, and the extrusion pressure is 2MPa. After the extrusion is completed, the bio-based fiber is obtained;
[0014] Step S2: Use hydrophobic modified slurry to size the bio-based fiber by high-pressure sizing, control the bio-based fiber delivery tension to 60-65mN, and the winding tension to 65-70mN. After slurrying, dry it in sections, the temperature of the first section is 136-138°C, the temperature of the second section is 130-132°C, the temperature of the third section is 98-110°C, and the temperature of the fourth section is 90-92°C. Control the sizing rate to ensure that the sizing rate is 4.8-5.2%. After sizing, plain weave is performed at a weaving speed of 520-550rpm / min. After weaving, place it at 70-80°C for shaping treatment. After treatment, a bio-based fiber membrane is obtained.
[0015] Furthermore, the preprocessing process in step S1 includes the following steps:
[0016] The bio-based polyamide material was placed in a vacuum oven at 60°C for drying pretreatment for 6 hours, taken out and cooled to room temperature for standby use.
[0017] Furthermore, in the melt spinning process in step S1, the outlet diameter of the melt spinning machine is 0.30 mm.
[0018] Furthermore, the bio-based polyamide material is bio-based PA11.
[0019] Furthermore, the hydrophobically modified slurry for high pressure sizing is prepared by the following steps:
[0020] Add 5-difluoromethoxy-2-mercapto-1H-benzimidazole to anhydrous ethanol, stir to dissolve, then add dichloromethane and vinyltrimethoxysilane, stir to mix, add initiator and catalyst, react under 30W ultraviolet light for 20 minutes to obtain a fluorine-containing silane solution, add polypropylene resin to the fluorine-containing silane solution, stir at high speed to obtain a hydrophobically modified slurry.
[0021] Furthermore, the usage ratio of anhydrous ethanol, 5-difluoromethoxy-2-mercapto-1H-benzimidazole, dichloromethane, vinyltrimethoxysilane, initiator, catalyst and polypropylene resin is 40mL: 0.22-0.23g: 60mL: 11.5-12.0mL: 0.02g: 0.01g: 3.1-3.2g.
[0022] Furthermore, the initiator is 2,2-dimethoxyphenylacetophenone; and the catalyst is triethylenetetramine.
[0023] Beneficial effects of the present invention:
[0024] (1) The bio-based waterproof and breathable glove lining material prepared by the present invention is formed by hot-pressing a PP non-woven fabric and a bio-based fiber film. In the double-layer composite structure, the bio-based fiber film is the outer layer and the PP non-woven fabric is the inner layer. The outer layer of the bio-based fiber film is obtained by melt spinning, hydrophobic modification and weaving of a bio-based PA11 material. The bio-based fiber film has a fine and uniform microporous structure, and the pore size and distribution are uniform. At the same time, the prepared bio-based glove lining material has excellent waterproof, breathable and antibacterial properties.
[0025] (2) The bio-based fiber membrane prepared by the present invention is modified by a hydrophobic modified slurry. The fluorinated silane solution in the hydrophobic modified slurry has good hydrophobicity. At the same time, the imidazole ring structure of the silane side chain in the fluorinated silane solution has excellent antibacterial properties, which helps to improve the antibacterial effect of the glove lining material. Then, the PP non-woven fabric of the inner layer of the bio-based fiber membrane is water-absorbent. After being made into the glove lining material, the outer bio-based fiber membrane has excellent waterproof properties. The inner PP non-woven fabric can absorb the heat and sweat generated by the human body, and then diffuse through the outer layer to promptly remove the excess heat and sweat generated by the human body during activities, maintain a relatively comfortable and suitable condition inside, and have excellent waterproof and breathable properties. In addition, the bio-based PA11 material is made of 100% castor oil bio-based. The present invention provides a modification and application direction of a bio-based PA11 material.
