Technical Field

The invention relates to the technical field of ball liner manufacturing, in particular to a manufacturing method of a delaminating yarn liner.

Background

At present, a glue-bonded leather ball consists of an inner tube, a framework layer, an adhesive coating layer and leather from inside to outside. The inner tube has the functions of storing gas and keeping certain air tightness; wrapping or winding a proper amount of chemical fiber fabric or yarn on the surface of the inner tube to form a framework layer, then encapsulating, putting into a mold, and vulcanizing to obtain a semi-finished product, namely a middle tube; the surface of the middle tyre is sequentially polished, powdered and coated with solvent glue, the back of the leather is also coated with solvent glue, and finally, the surfaces are mutually bonded to prepare the final finished product. However, in the manufacturing process of the inner tube in the prior art, the finished ball manufactured by the common yarn winding bladder has poor softness, poor elasticity and unsatisfactory hand feeling and foot feeling of the ball body.

Disclosure of Invention

The invention aims to provide a method for manufacturing a delaminating yarn liner, which adopts a rubber liner to be separated from yarn to form delaminating, effectively improves the softness of a product, stabilizes the balance performance of the product, and achieves the aim of achieving the same effect as a full hand sewn ball in hand and foot feel.

In order to solve the technical problem, the invention provides a method for manufacturing a delaminating yarn liner, which comprises the following steps:

firstly, inflating a rubber liner;

secondly, performing circumference measurement on the inflated rubber liner;

thirdly, brushing a separating treatment agent on the outer wall of the inflated rubber liner to facilitate the separation of the rubber liner from the outer layer yarns;

fourthly, dry winding yarn on the outer wall of the rubber liner of the brushing off treatment agent;

fifthly, strong glue is applied to the dry winding yarn to independently fix the peripheral winding yarn;

sixthly, dispensing glue on the dry winding yarns which are subjected to the strong glue, so that the dry winding yarns have the effects of sticking, filling and sealing and fixing and smooth surfaces;

seventhly, performing constant-pressure drying on the yarn winding layer;

and eighthly, carrying out degassing and delaminating on the inflated rubber liner to obtain the delaminating yarn liner.

Preferably, the super glue is formed by mixing white latex, a curing agent, super glue and a mildew preventive.

Further preferably, the time for dry winding the yarn is 2 minutes.

More preferably, the time for super glue is 2 minutes.

The invention has the beneficial effects that: after the circumference of the rubber liner is measured, the shape-separating treatment agent is brushed firstly, then the yarn is wound for 2 minutes in a dry mode, and then the yarn is wound for 2 minutes in a strong glue mode, so that the inner liner is separated after the yarn is wound, the appearance yarn is tightly combined, the softness of the product is effectively improved, the balance performance of the product is stabilized, and the hand feeling and the foot feeling can achieve the same effect as those of a full-hand seam ball.

Detailed Description

The present invention will be described in further detail with reference to examples.

A method for manufacturing a delaminating yarn bladder comprises the following steps:

firstly, inflating a rubber liner;

secondly, performing circumference measurement on the inflated rubber liner, and performing measurement on corresponding specification and size according to the requirements of different balls, so as to ensure the size requirement and achieve the specified standard circumference range of the finished yarn winding liner;

thirdly, brushing a separation treatment agent on the outer wall of the inflated rubber liner to facilitate the separation of the rubber liner and the outer layer yarns, so that the softness of the yarn winding liner is improved, and the impact strength of the yarn winding liner is ensured;

fourthly, dry winding yarns on the outer wall of the rubber liner brushed with the shape separating treatment agent, enabling the rubber liner and the outer layer yarns to be in a separated state through the shape separating treatment agent, enabling the rubber liner and the yarns to be isolated and not stuck, and forming delamination;

fifthly, glue water which is formed by mixing white latex, a curing agent, super glue and a mildew preventive is added on the dry winding yarn to independently fix the peripheral winding yarn, and the roundness and the strength of a yarn winding liner are ensured by the super glue;

sixthly, dispensing glue on the dry winding yarns which are subjected to the strong glue, so that the dry winding yarns have the effects of sticking, filling and sealing and fixing and smooth surfaces;

seventhly, performing constant-pressure drying on the yarn winding layer;

and eighthly, carrying out degassing and delaminating on the inflated rubber liner to obtain the delaminating yarn liner.

The ball product made of the delaminating yarn liner has stronger bouncing force, softer ball body and better balance degree; the hand feeling and foot feeling of the ball body are the same as those of hand-sewn football and volleyball, and the ball body can be used for manufacturing match-grade football, volleyball, basketball, handball, football and the like.

The above description is only a preferred embodiment of the present invention, and for those skilled in the art, the present invention should not be limited by the description of the present invention, which should be interpreted as a limitation.
