Problems solved by technology

[0003] At present, the existing gloves are made of materials such as leather, rubber and cloth, especially the leather and cloth have a limited fit with the hand, which will restrict the movement of the hand to varying degrees, and the style is relatively monotonous
Especially for sports such as golf, the golf gloves currently on the market are too loose and loose, which affects the wearer's grip and strength, which in turn affects the performance.

Embodiment 1

[0028] (1) Cut corn stalks into pieces, sieve, and grind to obtain corn fiber powder with a length of 0.1-0.3mm, add the corn fiber powder into a solvent, stir and let it stand for 4 hours, after the corn fiber is fully swollen, add a starter, Mix evenly, high-temperature fermentation, hydrolysis, purification and polycondensation to obtain a polylactic acid high polymer with a viscosity of 280mPas.

[0029] (2) Transfer the polylactic acid polymer to the 3D printing device, adjust the orientation of the 3D printing according to the analysis and added hand data, and extrude the polylactic acid polymer from the port at 190°C at a speed of 0.6m / s Then, an integrated corn glove is formed on the three-dimensional receiver covered with a layer of conductive material.

[0030] (3) The corn glove was trimmed and cured at 110°C for 30 minutes to obtain a 3D printed corn glove with a thickness of 3 mm and a micro-nano structure on the surface.

Embodiment 2

[0032] (1) Shred, sieve, and grind corn stalks to obtain corn fiber powder with a length of 0.1-0.3mm, add the corn fiber powder to a solvent, stir and let stand for 6 hours, after the corn fiber is fully swollen, add a starter, Mix evenly, high-temperature fermentation, hydrolysis, purification and polycondensation to obtain a polylactic acid high polymer with a viscosity of 460mPas.

[0033] (2) Transfer the polylactic acid polymer to the 3D printing device, adjust the orientation of the 3D printing according to the analysis and added hand data, and extrude the polylactic acid polymer from the port at 220°C at a speed of 0.9m / s Then, an integrated corn glove is formed on the three-dimensional receiver covered with a layer of conductive material.

[0034] (3) The corn glove was trimmed, cured at 110°C for 60 min and other post-treatments to obtain a 3D printed corn glove with a thickness of 5 mm and a surface containing micro-nano-scale structures.

Embodiment 3

[0036] (1) Cut corn stalks into pieces, sieve, and grind to obtain corn fiber powder with a length of 0.1-0.3mm, add the corn fiber powder into a solvent, stir and let it stand for 4 hours, after the corn fiber is fully swollen, add a starter, Mix evenly, high-temperature fermentation, hydrolysis, purification and polycondensation to obtain a polylactic acid high polymer with a viscosity of 360mPas.

[0037] (2) Transfer the polylactic acid polymer to the 3D printing device, adjust the orientation of the 3D printing according to the analysis and added hand data, and extrude the polylactic acid polymer from the port at 200°C at a speed of 0.75m / s Then, an integrated corn glove is formed on the three-dimensional receiver covered with a layer of conductive material.

[0038] (3) The corn glove was trimmed and cured at 110°C for 50 minutes to obtain a 3D printed corn glove with a thickness of 3.6 mm and a micro-nano-scale structure on the surface.

Abstract

The invention provides a corn glove based on 3D printing and a preparation method of the corn glove. The preparation technique of corn fibers is combined with the 3D printing technique to prepare the corn glove; corns are screened and ground, and swelled and fermented to obtain a polylactic acid high polymer; the high polymer is transferred into a 3D printing device, and the corn glove can be printed according to the scanned hand data. The corn glove prepared by use of the method is capable of fitting with the hand of a human body just like skin, and is capable of achieving the effects of keeping warm and preventing the hand without limiting the movement of the hand; besides, the glove is comfort and flexible, moisture and air permeable, high in strength, good in elasticity, and especially suitable for golf sports. The method is flexible and changeable; a special surface can be added to the outer surface of the glove according to the requirement of a customer, so that the holding force of the glove can be improved and the corn glove can better conform to the requirements.

Description

Technical field: [0001] The invention belongs to the technical field of textile materials, and in particular relates to a 3D printing-based corn glove and a preparation method thereof. Background technique: [0002] With the rapid development of technology, 3D printing technology is not only used in traditional manufacturing fields, but also successfully applied in medicine and biomedical engineering. 3D printing, also known as three-dimensional printing and additive manufacturing, uses layered processing, superposition forming, etc. to divide the model into layers of tens of microns to hundreds of microns, and alternately add liquid, powder, wire or blocks layer by layer. After the solid model is formed, it is cured, peeled off, polished, drilled and electroplated, etc., and finally a 3D printed model with a smooth surface is obtained. [0003] At present, the existing gloves are made of materials such as leather, rubber, and cloth. In particular, the degree of fit between...
